     In the neoclassical theory of the firm the profit motive suffices to induce optimal behavior of the firm with respect to its environment. In real firms, viewed as multi-agent organizations, there are a variety of principal-agent type problems and usually little clear consensus concerning what constitutes optimal behavior. Thus, it is common wisdom that real firms depart significantly from the neoclassical ideal, but the extent of such departures and their importance are the subjects of considerable differences of opinion. These competing perspectives are important in a variety of contexts (e.g., antitrust) but are particularly well-defined when it comes to environmental regulatory policy. Economists commonly assert that market forces are sufficient to get firms to behave in ways the improve social welfare, and that appropriate pollution prices can be depended upon to remedy pollution problems. Against this view industrial ecologists have provided substantial empirical evidence that firms often fail to adopt technologies and practices that are in their own self-interest, and thus market mechanisms provide weak foundation for well-functioning environmental policies.
    We apply agent-based modeling techniques to a model of firm formation and evolution in an attempt to better understand the origin of sub-optimal behavior on the part of business firms. Specifically, we treat several incentive problems that exist in typical corporate organizations in an attempt to rationalize the behavior of purposive agents with empirical data on the failure to adopt cost saving technology. We utilize data from various pollution emission databases in the construction of our models. This is work in progress and preliminary results will be reported.
