Organizational economics examines how economic logic applies to transactions within firms and the costs and benefits of different organizational structures, compensation plans, and management decisions. It includes the study of transaction cost theory, agency theory, and contract theory. The Chicago School of Economics influenced organizational economics, particularly the work of George Stigler who developed the Economic Theory of Regulation which argues that interest groups will shape laws and regulations to their benefit, something known as regulatory capture. Public choice theory also informs organizational economics by using economic tools to analyze political behavior and interactions between self-interested political actors.
