Five studies examined the effect of breadth and depth of foreign experiences on generalized trust. Study 1 found that the breadth (number of countries traveled) but not the depth (amount of time spent traveling) of foreign travel experiences predicted trust behavior in a decision-making game. Studies 2 and 3 established a causal effect on generalized trust by experimentally manipulating a focus on the breadth versus depth of foreign experiences. Study 4 used a longitudinal design to establish that broad foreign travel experiences increased generalized trust.

A longitudinal study found that the psychological approach individuals take when immersed in a general multicultural environment can predict subsequent career success. Using a culturally diverse sample, we found that "multicultural engagement" — the extent to which students adapted to and learned about new cultures — during a highly international 10-month master of business administration (MBA) program predicted the number of job offers students received after the program, even when controlling for important personality/demographic variables.

Recent years have seen extensive investigation of the information aggregation properties of markets. However, relatively little is known about conditions under which a market will aggregate the private information of rational risk averse traders who optimize their portfolios over time; in particular, what features of a market encourage traders to ultimately reveal their private information through trades? We consider a market model involving finitely many informed risk-averse traders interacting with a market maker.
