AN ANALYSIS OF BEHAVIOR AND PERFORMANCE IN THE FOOD RETAILING INDUSTRY USING EXPERIMENTAL BUSINESS GAMING

This research tested hypotheses concerning the effects of organizational affiliation, differences among managers nested within organizational affiliation, degree of price competition and selected demographic and psychological traits of managers on economic behavior and performance. Experimental gaming in a behavioral science laboratory was used with a group of 60 subjects who were managers of Indiana supermarkets. The results support the influence of economic factors on the behavior and performance of managers. Degree of price competition imposed by the researchers significantly affected pricing decisions. At the same time, factors not usually considered in the static theory of the firm, such as organizational affiliation, had a significant influence on behavior and performance. While psychological and demographic traits generally did a poor job of explaining manager behavior, their effect may have been masked by the main treatments to which subjects were exposed. Realism in the experiment was not as high as expected, but the approach used was judged to be superior to alternative approaches.     

Investment and Competitive Matching

We study markets in which agents first make investments and are then matched into potentially productive partnerships. Equilibrium investments and the equilibrium matching will be efficient if agents can simultaneously negotiate investments and matches, but we focus on markets in which agents must first sink their investments before matching. Additional equilibria may arise in this sunk‐investment setting, even though our matching market is competitive. These equilibria exhibit inefficiencies that we can interpret as coordination failures. All allocations satisfying a constrained efficiency property are equilibria, and the converse holds if preferences satisfy a separability condition. We identify sufficient conditions (most notably, quasiconcave utilities) for the investments of matched agents to satisfy an exchange efficiency property as well as sufficient conditions (most notably, a single crossing property) for agents to be matched positive assortatively, with these conditions then forming the core of sufficient conditions for the efficiency of equilibrium allocations.     

Production System Development for Expert Systems Using a Recursive Partitioning Induction Approach: An Application to Mortgage,Commercial, and Consumer Lending

The concepts of expert systems and decision support systems have received considerable attention recently. While systems have been proposed for various problem areas in business, difficulties still exist in the knowledge acquisition phase of development. This paper presents a recursive partitioning analysis (RPA) approach to knowledge acquisition. The RPA production system approach was applied to data sets representing the mortgage, commercial, and consumer lending problems. Comparison of the classification rates across these problems to the results of a generalized inductive inference production system (Quinlan's ID3 algorithm) and across the mortgage and commercial lending problems to traditional statistical modeling approaches indicated that the RPA approach provided superior results while using fewer variables.
