As the world’s population grows and urbanization continues, the global waste crisis is becoming more severe, especially in developing countries. Without proper waste management, they may encounter various environmental and health risks. Biological technologies are regarded as promising waste management and recycling approaches in developing countries due to their cost-effectiveness and capability to handle diverse waste categories. One prominent technology in this aspect is the vermicomposting of organic waste utilizing the black soldier fly larvae. Nevertheless, significant financial resources are still (...) necessary to advance and expand biological waste treatment, which requires the participation of businesses. By examining waste management companies listed on the Vietnamese stock market, we highlight two challenges that hinder the adoption and scaling of the waste treatment system using black soldier flies and potentially other biological technologies in Vietnam. Specifically, the business regards the environmental services they offer primarily as a means to generate profit rather than as a genuine commitment to environmental preservation, and the values of companies operating in the environmental sector, particularly in waste management, have been significantly undervalued by the Vietnamese investing public. Therefore, we advocate for societal shifts toward the eco-surplus culture and apply the semiconducting principle of monetary and environmental values exchange to address the problem. (shrink)

For many years, the relationship between the financial system and economic growth has attracted the attention of scholars intending to uncover the direction of the relationship. The stock market is a part of the financial system and plays an essential role in channelling equity funds into the economy and creating liquidity for the equity instruments. A substantial empirical study postulates that the stock market can boost the economic growth of an economy. However, other studies assert that, (...) at best, the stock market is an unimportant economic driver. (shrink)

This paper aims at answering the question whether the VN30 index futures introduction has an impact on stock market volatility in Vietnam. Apply GARCH model of volatility with additive dummy variable from 28/7/2000 to 10/9/2020, the result shows that when the first listed index futures contract appears, it makes the volatility of VNIndex increases. The result is still robust after excluding the turmoil period of Vietnam stock market. This paper implies that policy maker should be more (...) careful in promoting derivatives market in Vietnam.

As one of the most contagious diseases in history, Corona Virus (COVID-19) spread rapidly around the world infecting millions of people in the year 2020. Besides killing huge number of persons, the calamity not only ignited severe panic and chaos among them, it even affected vast businesses and stock markets around the globe. This study was undertaken to investigate those determinants, which affected the extent of stock market investors’ behavior in Pakistan during spread of COVID-19. Data was (...) collected from various individual investors, representing a high response rate of about 86.5% from 167 respondents. From the analysis it was indicated that most important and significantly influencing determinants on investment decisions in Pakistan Stock Markets are pertinent to: ‘getting rich quickly, loss aversion, fear of losses, expected corporate earnings and dividends, gut feelings on the economy, previous performances of firm’s stock and opinions of its majority shareholders, and eventually, the recommendations of brokers and family/friends. Our findings would first, assist in understanding the most common behavioral patterns of investors and secondly, determine to show the adequate paths, which lead towards the growth of Pakistan Stock Market.

This thesis consists of three substantive studies about the Vietnam stock market. In particular, I study the asymmetric information, corporate governance (CG) practices, and foreign investment of publicly listed companies in Vietnam, presented in Chapters 2, 3, and 4, respectively. In Chapter 2, I investigate the effectiveness of a market surveillance system (MSS) on improving the market quality of the Vietnam stock market, as measured by liquidity and informed trading level. I find that (...) class='Hi'>market liquidity decreased after the introduction of the MSS, and that the effect is more pronounced for small firms. Although informed trading, on average, does not change significantly after the MSS, subsample analysis indicates a significant decrease in informed trading among large and liquid firms. In Chapter 3, I investigate the relationship between firms’ CG practices and informed trading. I find a negative relationship between the two variables. Firms with better CG practices have a lower level of informed stock trading. Moreover, a natural experiment on a shock of firms’ CG practices generated by the CG policies shows that the negative relationship between CG practices and informed trading is a causal one, in which a change in the former causes a change in the latter. In another analysis around the implementation of the MSS, I find that the implementation of the surveillance system affects the relationship between the two variables, and this effect is driven by large and liquid firms. In Chapter 4, I investigate whether foreign investors in the Vietnam stock market are informed about firms’ performance. Using the residuals of foreign investor ownership as a measure of the abnormal foreign investor holding, I find that the abnormal foreign investor holding is positively correlated with firm performance in the following one year. I also find a positive correlation between abnormal foreign investor holding and the stock returns in the next three quarters. These findings indicate that foreign investors are informed about the firms up to a one-year period. (shrink)

The stronger the level of economic integration between countries, the greater the need to study the formation patterns of the stock market reaction to the financial information signals. This concerns the Ukrainian stock market, which is now in its infancy, and which reaction to financial information signals is sometimes ambiguous. The research aims to identify the formation patterns of return and volatility indicators of the Ukrainian stock market reaction to the US financial information signals. (...) To assess the direct nature of US financial information signals effect on the PFTS stock index, the GARCH econometric modeling toolkit was applied. The research information base is the PFTS stock index and the Federal Reserve System financial information signals at the discount rate for 2000–2019. The fetch is divided into intervals corresponded to the ascent and decline phases of the financial cycle. It was found that an unforeseen increase in the discount rate at the financial cycle decline phase by 25 basis points decreases the PFTS stock index return, on average by 2.9%. Besides, the hypothesis about the general change stabilizing effect in the discount rate on the Ukrainian stock market volatility at the financial cycle growth phase was confirmed. Nevertheless, for investors, the most essential is the regulator’s monetary signals in the discount rate at the financial cycle decline phases rather than at the ascent phases because there is a more significant increase in the volatility level.

The subprime mortgage crisis in the United States (U.S.) in mid-2008 suggests that stock prices volatility do spillover from one market to another after international stock markets downturn. The purpose of this paper is to examine the magnitude of return and volatility spillovers from developed markets (the U.S. and Japan) to eight emerging equity markets (India, China, Indonesia, Korea, Malaysia, the Philippines, Taiwan, Thailand) and Vietnam. Employing a mean and volatility spillover model that deals with the U.S. (...) and Japan shocks and day effects as exogenous variables in ARMA(1,1), GARCH(1,1) for Asian emerging markets, the study finds some interesting findings. Firstly, the day effect is present on six out of nine studied markets, except for the Indian, Taiwanese and Philippine. Secondly, the results of return spillover confirm significant spillover effects across the markets with different magnitudes. Specifically, the U.S. exerts a stronger influence on the Malaysian, Philippine and Vietnamese market compared with Japan. In contrast, Japan has a higher spillover effect on the Chinese, Indian, Korea, and Thailand than the U.S. For the Indonesian market, the return effect is equal. Finally, there is no evidence of a volatility effect of the U.S. and Japanese markets on the Asian emerging markets in this study. (shrink)

This study examines the effects of ownership structure on firm performance in the Vietnamese stock market using a sample of 76 manufacturing companies listed on the Ho Chi Minh Stock Exchange (HOSE) during 2007-2015. Firm performance is measured by Tobin’s Q, and ownership structure is investigated in three different aspects: managerial ownership, block ownership and state ownership.

The Ukrainian PFTS stock index volatility reaction as a whole and its constituent economic sectors (“Basic Materials”, “Financials”, “Industrials”, “Oil & Gas”, “Telecommunications”, “Utilities”) to seven non-monetary US information signals (“Consumer price index”, “Personal spending”, “Unemployment rate”, “Gross domestic product”, “Industrial production”, “Consumer confidence”, “Housing starts”) was carried out for the period 2000–2017 on the basis of closing stock quotations in the trading day format. To assess the “surprise” component direct influence nature of the USA selected non-monetary information (...) signals on the PFTS stock index, an AR-GARCH econometric modelling device was used. The results achieved clearly indicate the presence of some PFTS stock index economic sectors heterogeneous reaction to the United States individual non-monetary information signals announcement. For example, such economic sectors as “Basic Materials”, “Financials”, and “Oil & Gas” volatility response to the US non-monetary information signal “Consumer price index” “surprise” components the opposite of the overall PFTS stock index reaction. It can also be concluded that the United States non-monetary information signals influence on the Ukrainian stock market volatility depends not only on the financial cycle phase and data frequency, but also on the PFTS stock index economic sector.

In this study, we examine the own- and cross-effects of the return and volatility spillover between the equity markets of Vietnam and the two ASEAN countries, namely, Singapore and Thailand using monthly stock returns. In attempt to explore the level and magnitude of the spillover effects of the other markets on the Vietnamese stock market, we apply the multivariate generalized autoregressive conditional heteroskedasticity (MGARCH) framework. By utilizing the time-varying conditional volatility and conditional correlations between the stock (...) markets which are resulted from estimation of the GARCH-BEKK model, the study also further shed light on the issues of portfolio diversification. In general, the study found the weak return linkages among the markets. Specifically, the study found no return linkages between Vietnam and Thailand and the unidirectional relationship between Vietnam and Singapore. However, the volatility linkages are highly significant for the three stock markets. It is found that the shock transmission relationship between emerging markets (i.e. Vietnam, Thailand) and developed market (i.e. Singapore) is unidirectional in direction to the emerging markets and the volatility transmission relationships between those are bidirectional. Besides, the variation in Vietnamese stock volatility is found to be more strongly influenced by the past own-shock effects than the past cross-shock effects. This indicates the low level of financial integration of Vietnam into the regional markets and implies the potential rooms for the international portfolio diversification gains. The findings on the return and volatility linkages have several important implications for both investors and policy makers. Firstly, because of the low correlations between the stock markets found, the investors can earn the gains from the portfolio diversification in the three markets. Secondly, the Vietnamese policy makers should be concerned with the harmful volatility spillover originating in the Thailand market that can affect the stability of the stock market. Thirdly, the implication is related to the monetary policy. The finding that the own shock transmissions have the strongest impact on the Vietnamese market’s volatility suggest that the policy makers should pay more attention to the domestic shocks so that the adequate and timely policy can be made.

A failed market, or asymmetric information, is a well-known economic concept. This phenomenon can be witnessed in a variety of markets. However, the repercussions of information asymmetry are thought to be more substantial in the stock market. Because, in addition to measurable economic impact, knowledge asymmetry harms trust. The Vietnamese stock market has experienced several successes since its creation, yet it still has many restrictions typical of a young market. The numerous violations of the (...) subjects on the market in recent years reflect those restrictions. Information issues, or more broadly, information asymmetry, are primarily responsible for these errors. The goal of this study was to analyze and assess the degree of information asymmetry in the Vietnamese stock market during a five-year period (2018 – 2022). The author tests the information asymmetry effect using GARCH models for VN-Index data and measures Adverse Selection Component (ASC) using the Glosten & Harris model for the 100 largest capitalization companies on the Ho Chi Minh City Stock Exchange (HOSE). The findings demonstrate information asymmetry, and the ASC value for the entire study period is 89.53%. This empirical finding serves as the foundation for formulating suitable policy recommendations for every market participant, aiding in the growth of a productive, equitable, open, and transparent Vietnamese stock market.

In the boiling atmosphere of the Vietnamese stock market, it is time to mention a few misconceptions from Vietnamese investors. (Vietnam Investment Review, 27-6-2007).

The novel coronavirus (COVID-19) has imperatively shaken the behavior of the global financial markets. This study estimated the impact of COVID-19 on the behavior of the financial markets of Europe and the US. The results revealed that the returns of the S&P 500 index have been greatly affected by a lockdown in the US owing to COVID-19. However, the health crisis generated due to the novel coronavirus significantly decreased the stock returns of the Nasdaq Composite index. The results also (...) showed that the economic crisis generated from the pandemic in Spain has had more impact on the IBEX 35 as compared to the health crisis itself. On the other hand, in the long-run, Italy’s stock markets are more affected by the health crisis as contrasted with the economic crisis, while, in the short-run, both lockdown conditions and economic instability lower the stock returns of FTSE MIB. The UK stock markets witnessed that in the short-run, deficiency of health management systems imperatively damaged the stock returns of the London Stock Exchange. The investigation revealed that deficiency of health systems and lockdown conditions have imperatively damaged the structure of financial markets, inferring that sustainable development of these nations is at risk due to COVID-19. The study suggested that governments should allocate more of their budget to the health sector to overcome a health crisis in the future. (shrink)

The paper deals with the topical issue of studying cyclic patterns in the economy and their practical application for the forecasts on the development of financial markets. The work aims to establish the features of the seasonal-cyclic patterns "The January barometer" and "The first five days of January" in the international financial markets in current conditions and to develop recommendations for the practical application of these patterns in the investment activities. The US stock market as an integral part (...) of the World financial market was chosen as a basis for research. The research was conducted by statistical processing of data on the values of the broad market index Standard & Poor's-500 for the period from 1950 to 2019. The study showed that the formation of forecasts about the annual growth or decline of the stock market index using the seasonal-cyclic patterns "The January barometer" and "The first five days of January" can show a high result in cases where the growth of the Standard & Poor's-500 index by the results of both the first five days of January and the results of the entire month of January of this year is a positive value. Otherwise, forecasting based on these instruments is not advisable. The best results (the forecast efficiency was 93.3%) were achieved with the joint application of both cyclic patterns. The practical application of the research results makes it possible to improve the efficiency of investment activities in international financial markets. (shrink)

The main goal of the article is a further development of the usage of income and comparable approaches to company valuation aimed at defining market capitalization sensitivity to value changing in the conditions of dynamization of internal and external business parameters. The relevance of the researched topic is determined by the importance of establishing the factors influencing the change in company market capitalization based on the synthesis of approaches to company valuation. To obtain the results of the study, (...) the following methods were used: structural and logical analysis – to improve the process approach to company valuation in the context of determining the impact of its change on market capitalization; discounted cash flow method (DCF-model) – to determine the value of the enterprise based on the income approach; comparable companies method – to determine the value of the company on the basis of a market approach; factor analysis method – to assess the impact of changes in value on company market capitalization; generalization and logical analysis – in conclusions building. The results of critical analysis of publications of domestic and foreign scientists on the application of company valuation methods identified the need of improvement the process approach to company valuation in the context of determining the impact of its change on the company market capitalization. To adequately assess company value, the use of a synthesis of income and market approaches is proposed. The implementation of the DCF-model and comparable companies valuation method while valuation of Private Joint-Stock Company “SKF Ukraine” allowed to establish that the greatest impact on the target metric (company market capitalization) has an average industry multiplier EV/EBITDA, terminal growth rate and weighted average cost of capital – 5.9 %, 3.2% and 2.7% respectively. The practical value of the results of the study is determined by the importance of forming a full analytical basis for establishing the attractiveness of the performance of joint-stock companies in the market and consolidating management decisionsin order to increase market capitalization.

Market crises amplify fear, disrupting rational decision-making of stock investment. This study examines the relationship between investors’ information priorities—such as intuition, company performance, technical analysis, and other factors—and their fear responses (freeze, flight, and hiding) during market crashes. Using the Bayesian Mindsponge Framework (BMF) to analyze data from 1,526 investors in China and Vietnam, the findings reveal complex dynamics. We found positive associations between investors’ prioritization of social influence and intuition for investment decision-making with being freeze (i.e., (...) not knowing what to do with the owned stock), between prioritization of professionals’ evaluation and intuition with fleeing (i.e. giving up stock investment permanently), and between prioritization of professionals’ evaluation and social influence with hiding (i.e., stopping investing in stock for a while). In contrast, prioritization of companies’ performance metrics (e.g., net profit, debt, etc.) was negatively associated with being freeze, fleeing, and hiding. Meanwhile, prioritization of professionals’ evaluation, technical analysis, and liquidity was negatively associated with being freeze, fleeing, and hiding, respectively. The study highlights the importance of disseminating transparent, accurate information through government and media channels, along with implementing financial education programs, to promote rational investment decisions and reduce fear-driven behaviors.

The article examines the process of formation inventory of the enterprise and determines the optimal volume of commodity resources for sale. A generalization of author’s approaches to the formation and evaluation of inventories of the enterprise is carried out. The marketing-logistic approach was applied for the purpose of distribution groups of commodity resources due to the risk of non-fulfillment the order for the supply of goods of the enterprise. In order to ensure an effective process of commodity provision of the (...) enterprises, the costs associated with the formation of inventories are determined. The formalized scheme of the formation commodity provision and the process of optimization inventory of the enterprise is offered. The analysis the structure of the company’s inventory is carried out, the volume of goods turnover is defined, the stocks are grouped for various clustering characteristics. To conduct the study, statistical information was used on commodity resources of the enterprises, statistical methods (grouping, structure analysis, estimation of dynamic series), tools for assessing the efficiency of inventory use, HML-FMR clustering were used. The necessity of using XYZ and ABC analysis is indicated in order to obtain more reliable results and forecast values of the product support of the enterprise. Economic-mathematical modeling is applied and graphically shown the difference in the formation of commodity resources by various features of HML-FMR clustering. The calculations allow the enterprise to determine the optimal amount of commodity resources in accordance with the needs of consumers and their solvent demand, to plan financial resources for the formation of inventories, to develop assortment policy in accordance with demand for products and their implementation. The results of calculations the volume of merchandising of the enterprise, taking into account the HML-FMR clustering affect the formation of final financial performance of the enterprise — income and profits.

This study investigated the impact of investor psychological bias on a firm’s market value. In detail, we examined the effect of investor overconfidence (optimism) and loss aversion (pessimism) on firm market value. We also aimed to investigate the moderating effect of corporate governance on the relationship between investor behavior biases and firm market value. This study used a sample of 143 firms listed on the Saudi Stock Exchange over the period from 2012 to 2021. The results (...) suggest that investor overconfidence affects a firm’s value positively. On the other hand, loss aversion is negatively associated with the firm’s market value. Furthermore, we find that corporate governance (measured by board size and board independence) enhances the positive association between overconfidence and firm market value. In contrast, we find that corporate governance seems to marginally mitigate the negative effect of loss aversion. (shrink)

Periodical reports are important information sources for investors and society to monitor, contribute to, and allocate resources to listed companies contributing to environmental sustainability. This article provides a preliminary investigation into environment-related information disclosure in annual reports of 61 representative companies in Vietnam, a country that has a rapidly developing stock market and is highly vulnerable to the impacts of climate change. It was found that although most of the companies’ reports disclosed the goals to pursue sustainability and (...) environmental protection (over 93%), only one-third of them genuinely reported investment in or research on environmental directions. The proportion of companies reporting detailed information on greenhouse gas emissions, energy consumption, water consumption, and waste production is relatively low; even among leading companies in sustainable development, the reporting rates for these indicators remained below 60%. We suggest that a separate mandatory annual report on environmental issues will increase businesses’ and society’s consciousness of environmental impacts. Transparent disclosure of environmental information will also offer an avenue to empower society to monitor, participate, and steer businesses toward sustainable development, thereby fostering an eco-surplus culture throughout the economic system.

An outstanding group of leaders left evidence that a richer and more sustainable democracy could be achieved with American independence and democratic principles integrated into a new republican form of government. They were moved by principles that are the very spirit of democracy. These principles are needed to enhance democracy and improve well-being. Using the constructivist tradition of grounded theory and Aristotle’s conception of abstraction, the article proposes a theory of the first principles of democracy based on substantive data: the (...) Declaration of Independence, the Articles of Confederation, The Federalist Papers, and the United States Constitution. Knowledge, fairness, human dignity, hope, unity, and security are the first principles of democracy and are regarded as the bedrock of democracy and a government framework for the people. This theory contributed to a formal model of democratic social change. It also contributes a conceptual framework that supports Solum’s semantic originalism, a theory of constitutional interpretation. The principles of democracy can revitalize democracy and provide new possibilities by protecting education as an innate human right, abolishing capital punishment, criminalizing private prisons on the stock market, and reevaluating the proportionality of prison sentences.

Purpose ‐ The purpose of this paper is to explore the "resource curse" problem as a counter-example of creative performance and innovation by examining reliance on capital and physical resources, showing the gap between expectations and ex-post actual performance that became clearer under conditions of economic turmoil. Design/methodology/approach ‐ The analysis uses logistic regressions with dichotomous response and predictor variables on structured tables of count data, representing firm performance as an outcome of capital resources, physical resources and innovation where appropriate. (...) Findings ‐ Key findings relevant to economic and business practice follow. First, a typical characteristic of successful Vietnamese firms in the transition period is their reliance on either capital resources or physical asset endowments. Second, poor performers exhibit evidence of over-reliance on both capital and physical assets. Third, firms that relied on both types of resources tended to downplay creative performance. Some evidence suggests that firms face more acute problem caused by the law of diminishing returns in troubled times. Fourth, the "innovation factor" has not been tapped as a source of economic growth. Research limitations/implications ‐ This study has some limitations. The size of the survey sample is approximately 150 firms, while the potential sample of > 300 should be possible in the future. When the size increases, the research could be expanded to include further variables that will help investigate more deeply into the related issues and business implications. With regard to the implications of the study, the absence of innovations has made the notion of "resource curse" identical to "destructive creation" implemented by ex-ante resource-rich firms, and worsened the problem of resource misallocation in transition turmoil. The Vietnamese corporate sector's addiction to resources may contribute to economic deterioration, through a downward spiral of lower efficiency leading to consumption of more resources. Practical implications ‐ Insights obtained from this study could save transition economies' resources which have almost always been considered sine qua non before any critical major policymaking, while this is not necessarily true, and in many cases, even counterproductive. Originality/value ‐ Original data set on Vietnam stock market are collected, processed, prepared and used by the authors. Original design by the authors for regression equations with dichotomous predictor variables: dependence on endowed physical assets, reliance on capital resources and significant signs of creative performance/innovations. Original idea of viewing "resource curse" as absence of innovation and due to uncreative "destructive creation" of poor-performing commercial operations by resource-rich firms is used in the paper. We have searched the literature in business research and found that the empirical results have not been previously reported. (shrink)

In this paper I argue that Christopher Kutz misapplies his theory of joint action when he attributes shareowners responsibilities on the basis of their intentional participation in the corporations in which they invest. Instead I propose that his theory of joint action should be used to attribute shareowners responsibilities on the basis of their intentional participation in the stock market. If shareholders’ accountability is grounded in their intentional participation in the stock market, then shareholders cannot take (...) responsibility for corporation’s individual actions. Instead they are solely responsible for the benefits they gain from holding shares if these are a result of moral wrongdoing and for this they should be held accountable. (shrink)

One famous scene in The Wolf of Wall Street (2013) is the dialogue between the young Jordan Belfort (Leonardo DiCaprio) and the expert trader Mark Hanna (Matthew McConaughey). Hanna is complaining that the stock market is unpredictable; it’s “fugazi … it’s fairy dust. It doesn’t exist. It’s never landed. It is not matter. It’s not on the element chart. It’s not real”. But the fact that something is unpredictable and non-physical does not imply that it does not exist. (...) On the other hand, its unpredictability, non-physicality, and the fact that the stock market trend is largely determined by investors’ beliefs, do make its nature difficult to grasp. -/- This special issue of Rivista di Estetica aims to explore the financial sector from an ontological point of view. While the ontology of money has been extensively studied, few scholars have focused on the stock market and, more generally, on those entities belonging to the investment landscape. Matters are made more complicated by the fact that the financial sector is characterized by an ever-increasing use of digital technology, including software elements that trade in the market themselves. We believe that a careful study of this phenomenon may help us better to understand the role of artificial agents in the social world. (shrink)

The coronavirus has affected almost all sectors of the economy. Some areas have suffered and declined, while others have developed and benefited from the pandemic. Due to the COVID-19 pandemic, economies around the world have experienced a downturn. The effects of the pandemic will undoubtedly reverberate around the world for decades to come. The global threat of the COVID-19 epidemic has greatly affected people, families, communities and businesses. Countries have begun implementing a wide range of measures both within and between (...) countries to combat the humanitarian and commercial impact of COVID-19. The effects of the worldwide epidemic and the emergency situations to be taken in this context were felt more and more in business life. Considering that the epidemic progressed very quickly, it was observed that it caused constant negative pressure on business and stock markets. This situation is interpreted as a harbinger of a global crisis. On the other hand, issues such as disruptions in supply and distribution channels, closure of workplaces and ports, disruption of customs processes, lack of manpower and decrease in consumption, operations in the stock market continued in a negative direction day by day. The consistent exposure of COVID-19 around the world, especially in developing economies, suggests that developing economies are seen as a major driver of macroeconomic instability compared to developed countries. After the initiation of economic reforms, with the increase of national income, aggregate production and employment, the trend of increasing economic volatility in developing economies has also been observed. Considering all this, it can be noted that the topic of the article is quite relevant. In the article, the negative impact of the pandemic on the economy of the world, as well as Azerbaijan, is examined in a broad aspect, and the methods of eliminating the damage caused by it are determined.

[1] You have a crystal ball. Unfortunately, it’s defective. Rather than predicting the future, it gives you the chances of future events. Is it then of any use? It certainly seems so. You may not know for sure whether the stock market will crash next week; but if you know for sure that it has an 80% chance of crashing, then you should be 80% confident that it will—and you should plan accordingly. More generally, given that the chance (...) of a proposition A is x%, your conditional credence in A should be x%.

Despite the numerous benefits of natural solutions, potential challenges and limitations impede their widespread adoption. A recent paper suggests these obstacles may include financial issues through the stock market and eco-deficit of environmental companies and investors. Specifically, natural solutions, such as biological waste management methods utilizing organisms like black soldier flies, face challenges due to financial considerations and the prevailing eco-deficit culture within the business and investment sectors.

Limitless is a movie (released in 2011) as well as a novel (published in 2001) about a tormented author who (plagued by a writer’s block) becomes an early user of an experimental designer drug. The wonder drug makes him highly productive overnight and even allows him to make a fortune on the stock market. At the height of his career, however, the detrimental side-effects become increasingly noticeable. In this article, Limitless is analysed from two perspectives. First of all, (...) building on the views of the French novelist Emile Zola, the novel is seen as the report of a closely monitored experiment. Subsequently, building on the phenomenology of Ludwig Binswanger, I will show how the cognitive enhancement drug not only boosts the protagonist’s information processing capacities, but also modifies his experience of space and time, his sense of spatiality, his way of being-in-the-world. On the basis of these (complementary) analyses I will indicate how genres of the imagination (such as movies and novels) may play a significant role in assessing the societal implications of emerging technological developments such as neuro-enhancement, especially during the preparatory or anticipatory stage.

A generalized information theory is proposed as a natural extension of Shannon's information theory. It proposes that information comes from forecasts. The more precise and the more unexpected a forecast is, the more information it conveys. If subjective forecast always conforms with objective facts then the generalized information measure will be equivalent to Shannon's information measure. The generalized communication model is consistent with K. R. Popper's model of knowledge evolution. The mathematical foundations of the new information theory, the generalized communication (...) model , information measures for semantic information and sensory information, and the coding meanings of generalized entropy and generalized mutual information are introduced. Assessments and optimizations of pattern recognition, predictions, and detection with the generalized information criterion are discussed. For economization of communication, a revised version of rate-distortion theory: rate-of-keeping-precision theory, which is a theory for datum compression and also a theory for matching an objective channels with the subjective understanding of information receivers, is proposed. Applications include stock market forecasting and video image presentation. (shrink)

In the last 10 years, after becoming the official member of WTO in 2007, Vietnam has made commitments to the comply with the US-Vietnam Bilateral Trade Agreement and other international economic agreements. Vietnam has also become a member of the AEC and entered into important free trade agreements, notably the Trans-Pacific Partnership. The financial integration of Vietnam in the global economy has been increasing rapidly. However, Vietnam also witnesses the unexpected economic fluctuations domestically and internationally. The global financial crisis, especially (...) the US financial crisis, exerts a major impact on Vietnam’s economy and its banking system. Accordingly, the real estate market, stock market and banking system in Vietnam have fluctuated remarkably. This article discusses the causes of the US financial crisis and analyses the US government’s solutions. The causes of the US financial crisis are distributed to lax lending standards, failures in regulations of derivates financial instruments, and lack of state control of banking systems. In this respect, recommendations are made for Vietnam’s case. (shrink)

The article analyses the impact of the sanctions of civilized countries on the Russian economy. Particular attention is paid to sectoral sanctions on the markets of oil and oil products, in the banking and financial sectors, as well as on the market of transport services. The authors analysed the prospects for expanding sanctions on the oil market for Russia in the context of setting a maximum price for the export of Russian oil by the main buyers. Conclusions are (...) drawn not only about the impact of sanctions on Russian oil production, but also about a possible decrease in prices for oil and other energy resources in the region. The authors positively assessed the US and EU anti-Russian sanctions in the financial sector. The impact of sanctions on the Russian banking system, insurance, and stock markets was studied. Particular attention was paid to the impact of disconnecting the banking system of the Russian Federation from the international payment system SWIFT. The authors also focused on the gradual division of the Russian economy under the influence of sanctions and trends in the energy market into the energy sector and the rest. It was found that the most affected by the sanctions were air transportation, mechanical engineering, and ferrous metallurgy sectors. Conclusions are drawn about the need to continue sanctions pressure on the Russian economy. High energy prices during the 200 days of the war with Ukraine allowed the Russian Federation to subsidize economic sectors that suffered from the war at the expense of the energy sector. A market reduction of the oil prices or their correction with the help of the sanctions policy should cause significant and irreversible damage to the Russian economy. (shrink)

This paper responds to recent developments in the field of sensory augmentation by analysing several technological devices that augment the sensory apparatus using the tactile sense. First, I will define the term sensory augmentation, as the use of technological modification to enhance the sensory apparatus, and elaborate on the preconditions for successful tactile sensory augmentation. These are the adaptability of the brain to unfamiliar sensory input and the specific qualities of the skin lending themselves to be used for the perception (...) of additional sensory information. Two devices, Moon Ribas’ Seismic Sense and David Eagleman’s vest, will then be discussed as potential facilitators of aesthetic experiences in virtue of the tactile sensory augmentation that these devices allow. I will connect the experiences afforded by these devices to the Kantian categories of the mathematical and the dynamical sublime, and to existing accounts of tactile sublimity. Essentially, the objects these devices make sensible, earthquakes for the Seismic Sense and digital information for the vest, produce pleasurable feelings of potential danger, awe, and respect. The subsequent acclimation to this new way of sensing and the aim to comprehend its sensed object are then discussed as possible objections to the interpretation of these experiences as sublime, and as aesthetic in general. To exemplify these issues and concretise my thesis of tactile sensory augmentation as a trigger of the sublime, I will outline an experiment to use the vest as an aid for faster decision making on the stock market.

The book consists of 16 chapters divided into three main parts, emphasizing the market system and financial-monetary control mechanisms. The book provides readers with significant economic advances. Thanks to a relatively extensive system of materials collected, chosen and computed over a long period of time from various domestic and international sources since Vietnam's independence. The book has highlighted the unresolved concerns and proposals based on examinations of the changing process of mechanisms and policies in general and for the financial (...) industry, banks and markets in particular. The study also focuses on Vietnam's real estate market, gold, stock market and US dollar market. (shrink)

In his book The Sensory Order, Hayek anticipates many of the central ideas behind what we now call the connectionist paradigm, and develops on this basis a theory of the workings of the human mind that extends the thinking of Hume and Mach. He shows that the idea of neural networks is can be applied not only in psychology and neurology but also in the sphere of economics. For the mind, from the perspective of The Sensory Order, is a dynamic, (...) relational affair that is in many respects analogous to a market process. The mind, as Hayek puts it, is a 'continuous stream of impulses, the significance of each and every contribution of which is determined by the place in the pattern of channels through which they flow' , so that the flow of representative neural impulses can be compared 'to a stock of capital being nourished by inputs and giving a continuous stream of outputs'.

This paper tackles the asymmetry of economic interests and geopolitics between developed and developing countries. Currently, the geopolitics presupposes that the majority of novel technologies are devised and designed in developed countries with their subsequent transfer to the developing countries. Moreover, in the context of the global crisis, the issue of de-dollarization is relevant from the political and economic points of view. Our specific focus is on the small oil countries and the issue how to get off the oil needle (...) in the painless way. Furthermore, the paper analyzes the rise of cryptocurrency that is envisaged as the substitute of the U.S. dollar which has been the world most dominating currency for the last several decades. This paper considers the global asymmetry which has the greatest impact on countries with economies dependent on energy exports. In the light of the diminishing returns from the sale of oil, we examine the ways for escaping this asymmetry. The authors consider the geopolitical asymmetry stemming from the dominance of the U.S. dollar, analyze the political situation and offer the pathways for the development of those economies where oil become an obstacle for economic development. The paper examines the ways of solving the above-mentioned problem by other states in detail and conduct the comparative analysis of the above issues in relation to the economy of Azerbaijan. From this case study we conduct a comparative analysis of the developed and developing countries taking into account the economic asymmetry and global economic and financial security. (shrink)

This chapter aims at describing the role of housing in the ageing population, on the example of Poland, which is one the fastest ageing country in the world. This issue is significant because housing well suited to the needs of older people means lower expenses in medical and social care. Seniors living in proper conditions remain not only longer healthy, but they may also stay longer active in the labor market. Housing adoption to the needs of an older population (...) means a particular challenge for Poland, where the majority of the housing stock was created in socialism and is inhabited by large by older people. It is crucial to raise awareness of age-friendly housing among the seniors, their relatives, architects, and policymakers. This purpose serves the first model apartment for seniors in Poland, which was created by the chapter's authors. (shrink)

In the given article the problems of choice as for the types and forms of debt and share financing on the developing and “frontier markets” with high interest rates have been considered, the definition of what kind of interest rates can be viewed as high and under which circumstances nominal interest rate and in which ones – the real interest rate is important for business. Also, the classification of debt and sharing financing is given and the comparative analysis of such (...) financing is made. Some close attention has been paid to the calculation of the real interest rate according to the inflation forecast. Recommendations concerning attracting of relatively cheap trade financing including international financial and credit organizations, development of operation factoring, financing from captive financial institutions of the exporters of the materials and equipment from the EU and the US have been grounded. The opportunity of relatively free of charge share financing through the mechanism of placing shares IPO/SPO is emphasized, exemplified by the results of placing shares on stock exchanges and their alternative platforms of issuing banks with businesses in Ukraine in 2005 – 2013. As a result, the conclusion concerning the necessity of thorough analysis of financial conditions on the developing and frontier markets before gaining such financing has been made. High interest rates within the average indicators even on the basis of prime rates do not necessarily mean absence of attractive conditions of financing. (shrink)

This paper argues that the reduced-form jump diffusion model may not be appropriate for credit risk modeling. To correctly value hybrid defaultable financial instruments, e.g., convertible bonds, we present a new framework that relies on the probability distribution of a default jump rather than the default jump itself, as the default jump is usually inaccessible. As such, the model can back out the market prices of convertible bonds. A prevailing belief in the market is that convertible arbitrage is (...) mainly due to convertible underpricing. Empirically, however, we do not find evidence supporting the underpricing hypothesis. Instead, we find that convertibles have relatively large positive gammas. As a typical convertible arbitrage strategy employs delta-neutral hedging, a large positive gamma can make the portfolio highly profitable, especially for a large movement in the underlying stock price.

I defend an account of sexual orientation, understood as a reflexive disposition to be sexually attracted to people of a particular biological Sex or Sexes. An orientation is identified in terms of two aspects: the Sex of the subject who has the disposition, and whether that Sex is the same as, or different to, the Sex to which the subject is disposed to be attracted. I explore this account in some detail and defend it from several challenges. In doing so, (...) I provide a theoretical framework that justifies our continued reference to Sex-directed sexual orientation as an important means of classifying human subjects. (shrink)

My topic is a certain view about mental images: namely, the ‘Multiple Use Thesis’. On this view, at least some mental image-types, individuated in terms of the sum total of their representational content, are potentially multifunctional: a given mental image-type, individuated as indicated, can serve in a variety of imaginative-event-types. As such, the presence of an image is insufficient to individuate the content of those imagination-events in which it may feature. This picture is argued for, or (more usually) just assumed (...) to be true, by Christopher Peacocke, Michael Martin, Paul Noordhof, Bernard Williams, Alan White, and Tyler Burge. It is also presupposed by more recent authors on imagination such as Amy Kind, Peter Kung and Neil Van Leeuwen. I reject various arguments for the Multiple Use Thesis, and conclude that instead we should endorse SINGLE: a single image-type, individuated in terms of the sum total of its intrinsic representational content, can serve in only one imagination event-type, whose content coincides exactly with its own, and is wholly determined by it. Plausibility aside, the interest of this thesis is also in its iconoclasm, as well as the challenge it poses for the diverse theories that rest on the truth of the Multiple Use Thesis. (shrink)

This paper concerns the familiar topic of whether we can have genuinely emotional responses such as pity and fear to characters and situations we believe to be fictional1. As is well known, Kendall Walton responds in the negative (Walton (1978); (1990): 195-204 and Chapter 7; (1997)). That is, he is an ‘irrealist’ about emotional responses to fiction (the term is Gaut’s (2003): 15), arguing that such responses should be construed as quasiemotions (Walton (1990): 245), of which their possessor imagines that (...) they are genuine emotions. This is not to deny that an experience in response to a fiction may have a phenomenology very like a given emotion, but to insist that, nonetheless, such responses are not real instances of the emotions which they resemble (Walton (1997)). So, in his most famous example, Charles, who experiences fear-like emotion in relation to a film which depicts the approach of evil slime, does not, despite appearances, experience genuine fear towards the slime, but only quasi-fear (Walton (1990): 195-204)2. Walton’s view presupposes the following view about the nature of emotion3. (shrink)

Against the backdrop of these works (Mitchell/Snyder and others), we propose an analysis of films with and about blind or visually disabled individuals that aims at exploring different modes of world perception. In our view, such an examination should not only discuss the question of “giving voice” and visibility to those who were formerly only represented in or by the media, or the fact that films belonging to what might be considered a “new disability documentary cinema” are dedicated to the (...) experience of disability from the point of view of those who deal with it. Rather, we examine films that do not restrict their field of vision to institutional context as cultural productions. These films allow the viewer to get to know different practices of seeing in the daily life of both blind or visually disabled and sighted people. In approaching these productions, we are interested in focusing on how the audio-visual regimes produce and structure our visual experience, translate it into a filmic grammar and thus not only create filmic patterns of blind perception but, at the same time, the cinematographic aesthetic of a so-called normal sightedness.

Abstract: The aim behind analyzing Google Stock Prices dataset is to get a fair idea about the relationships between the multiple attributes a day might have, such as: the opening price for each day, the volume of trading for each day. With over a hundred thousand days of trading data, there are some patterns that can help in predicting the future prices. We proposed an Artificial Neural Network (ANN) model for predicting the closing prices for future days. The prediction (...) is based on these features (date, opening price, highest price, lowest price, volume), which were used as input variables and (closing price) as output variable for our ANN model. Our model was created, trained, and validated using data set in JNN environment, which its title is “Google-Stock-Prices”. The model evaluation showed that the ANN model is able to predict correctly 99.48% of the validation samples. (shrink)
