This comparative field study evaluated the choices made by U.S., Portuguese, and Hong Kong Chinese evening MBA and graduating university business students when resolving business-related moral dilemmas. The authors developed hypotheses at the country level based on Hofstede’s ratings of each country’s national culture dimensions of power distance, uncertainty avoidance, individualism, and masculinity. The more individualistic U.S. respondents resolved the dilemmas with choices indicating less self-interest and more concern for unidentified others than did their Portuguese and Hong Kong Chinese counterparts, (...) who are from more collectivist societies. The authors discuss implications for future cross-cultural research on business dilemmas and for cooperative interactions among managers from these and other countries. (shrink)
