In a number of very influential publications, Epstein and Hoover (among other authors) have recently argued that a thoroughly micro-foundationalist approach towards economics is unconvincing for metaphysical reasons. However, as we show in this article, this metaphysical/social ontological approach to the debate fails to resolve the status of micro-foundations in the practice of economic modelling. To overcome this, we argue that endogenizing a model—that is, providing micro-foundations for it—correlates with making that model more complex. Specifically, we show that models with (...) more micro-foundations tend to have more parameters or variables. This matters, as there are well-established methodological reasons for preferring models with fewer parameters or variables—ceteris paribus. We therefore conclude that, from a practice-based point of view, micro-foundations are only defensible to the extent that they significantly improve the ability of the relevant model to fit the data of interest. In this way, we arrive at a practice-based, methodological reconceptualization of the debate surrounding the need for micro-foundations in economics. (shrink)

This thesis is an experimental study to investigate the operationalisability of the theory of social norms provided by Cristina Bicchieri. In Chapter 1 I critically summarise a main theme from recent literature and distinguish the accounts of norms based on social preferences from accounts based on social structure. I also summarise different theorists’ accounts of social norms as a social construct, in addition to surveying some issues scholars have raised empirically. Chapter 2 reviews the conceptual analysis of social norms by (...) Bicchieri as a social structure based account. Bicchieri’s conceptual analysis introduces three kinds of condition for norm identification. I review these in detail, and suggest hypothesis testing corresponding to each kind of condition. Chapter 2 briefly analyses a critical problem for Bicchieri’s theory. Chapter 3 provides philosophical background that supports the intentional concepts applied in Bicchieri’s analysis of social norms. I suggest that the Dennettian account of Intentional Stance is the best philosophical framework for Bicchieri’s account of social norms. I also argue that Revealed Preference Theory from economics is an application of the Intentional Stance. I conjecture that adopting the Intentional Stance and applying Revealed Preference Theory to empirical data can allow for improved operationalisation of Bicchieri’s conceptual analysis. In Chapter 4 I provide critical review of some key experimental work by Bicchieri and co-authors applying her conceptual analysis of social norms. I then provide a critical review of a widely used toolbox from the current economic literature for norm elicitation. Then I introduce a more rigorous experimental protocol for investigating social norms understood following Bicchieri’s analysis. The toolbox suggested in my thesis addresses limitations identified in Bicchieri’s empirical work. Chapter 5 presents design of the experiment administered as the core element of the thesis. Chapter 6 shows and analyses the results from the experiments described in Chapter 5. It also introduces the statistical models used in my thesis to assess the extent to which Bicchieri’s analyses successfully guides experimental identification of social norms. Chapter 7 offers concluding theoretical reflections, and discusses possible extensions of the research presented in this thesis. (shrink)

Agent-based models are increasingly important in social science research. They have two obvious apparent virtues: they can model complex macrosociological phenomena without strong assumptions about agents and without analytic solutions for models, and they seem to instantiate the methodological individualist program in a concrete way. We argue that the latter claim is false. After providing schematic accounts of ABM models and a first introduction to ways in which to characterize individualist explanations, we work through six conceptions of individualist explanations that (...) are decreasingly "less individualist" and argue that ABM-based explanations in the social sciences are not inevitably individualist in any of these senses. ABMs allow for explanatory relations among social entities and properties in the model environment and they are silent on what basic agents are, allowing social entities and properties to play basic explanatory roles.

It is currently common to conceive of the classic methodological individualism–holism debate in level terms. Accordingly, the dispute is taken to concern the proper level of explanations in the social sciences. In this paper, I argue that the debate is not apt to be characterized in level terms. The reason is that widely adopted notions of individualist explanations do not qualify as individual-level explanations because they span multiple levels. I defend this claim relative to supervenience, emergence, and other accounts of (...) the social world as levelled. Moreover, I discuss the consequences of this finding for the ongoing methodological individualism–holism debate. (shrink)

(1968 [1922]). It amounts to the claim that social phenomena must be explained by showing how they result from individual actions, which in turn must be explained through reference to the intentional states that motivate the individual actors. It involves, in other words, a commitment to the primacy of what Talcott Parsons would later call “the action frame of reference” (Parsons 1937: 43-51) in social-scientific explanation. It is also sometimes described as the claim that explanations of “macro” social phenomena must (...) be supplied with “micro” foundations, ones that specify an action-theoretic mechanism (Alexander, 1987).

A central argument for non-reductive accounts of group agency is that complex social entities are capable of exerting causal influence independently of and superseding the causal efficacy of the individuals constituting them. A prominent counter is that non-reductionists run into an insuperable dilemma between identity and redundancy – with identity undermining independent higher-level efficacy and redundancy leading to overdetermination or exclusion. This paper argues that critics of non-reductionism can manage with a simpler and more persuasive reductio strategy called mapping: allow (...) that group agents are causally efficacious in their own right and chart how their causal efficacy is carried out; how it relates to the causal efficacy of individual determiners; how it connects to the causal relevance of background structural factors. The focus exclusively on whether groups are or are not causally efficacious black-boxes implementation, while close attention to how causation is wired increases the visibility of individualist arguments and countenances structure-oriented explanations.

Recent efforts in a range of scientific fields have emphasised research and methods concerning individual differences and individualisation. This article brings together various scientific disciplines—ecology, evolution, and animal behaviour; medicine and psychiatry; public health and sport/exercise science; sociology; psychology; economics and management science—and presents their research on individualisation. We then clarify the concept of individualisation as it appears in the disciplinary casework by distinguishing three kinds of individualisation studied in and across these disciplines: Individualisation ONE as creating/changing individual differences (the (...) process that generates differences between individuals: intrapopulation or intraspecific variation/heterogeneity); Individualisation TWO as individualising applications (the tailoring or customising of something—information, treatment, a product or service, etc.—for an individual or specific group of individuals); and Individualisation THREE as social changes influencing autonomy, risk, and responsibilities (the process discussed under the rubric of sociological individualisation theory). Moreover, we analyse conceptual links between individualisation and individuality, and characterise different sorts of individuality that the disciplines study. This paper aims to promote interdisciplinary research concerning individualisation by establishing a common conceptual-theoretical basis, while leaving room for disciplinary differences. (shrink)

I argue that there are liberal reasons to reject what I call “Global Individualism”, which is the conjunction of two views strongly associated with liberalism: moral individualism and social individualism. According to the first view, all moral properties are reducible to individual moral properties. The second holds that the social world is composed only of individual agents. My argument has the following structure: after suggesting that Global Individualism does not misrepresent liberalism, I draw on some recent insights in social ontology (...) to show that it is inconsistent with the satisfaction of an important liberal principle related to the protection of individual rights over time. As I hold, to solve this problem we need to accept group agents acting as moral agents, which in turn commits us to the weaker notion of normative individualism (a view that is consistent with the existence of some group moral properties). I conclude with the suggestion that even this solution is costly for liberalism, for the conjunction of group moral agency and normative individualism makes the latter unstable and compels liberals to a much less individualistic stance than expected.
