At LEEPS we emphasize the laboratory study of learning processes within various institutions, and focus on their equilibrating tendencies. In the laboratory the institution can be varied in a systematic manner and information and payoffs can be observed, permitting sharp tests of learning models. Field evidence usually is not as sharp but is required to check for external validity and to observe social evolution at work. New model construction will certainly be in order as evidence accumulates on current models. Computer simulation will become an increasingly important part of model construction and analysis. Thus our work at LEEPS is complementary to that of many other researchers.
