Current Projects:

Laboratory for Experimental Economics and Political Science

The Laboratory is devoted to the development and applications of a laboratory experimental methodology for a broad range of disciplines. Laboratory experimental research began at Caltech in 1972 with the early experiments of Professor Charles R. Plott, who is the current Director of the Laboratory. Laboratory research is focused on basic research issues, applied research issues, and the development of supporting technology. Basic science includes the principles of behavior of single and multiple market systems in relation to parametric and institutional settings; the principles of behavior in relation to voting and political institutions; and the strategic behavior of game theory. Applied research includes policy related research, the development of prototype markets, smart markets, and the actual implementation of new forms of markets.

Social Science Experimental Laboratory

This facility represents the state of the art in experimental social sciences. It is dedicated to research in: Experimental Economics, Experimental Game Theory, Experimental Political Science, Experimental Finance, Market Design, Computational Economics.

The Turing Project

The Turing Tournament is a two sided tournament designed to find, on the one hand, the best computer programs to mimic human behavior, and on the other hand, the best computer programs to detect the difference between machine and human behavior.

Caltech Laboratory for Experimental Finance

This laboratory is dedicated to the study of financial markets. Its goal is to understand the basic principles, if there are any, behind the pricing, trading and information aggregation in financial markets. It challenges the pessimism expressed in Bachelier's quote that such markets defy scientific inquiry.
