MONITORING IN TEAMS: USING LABORATORY EXPERIMENTS TO STUDY A THEORY OF THE FIRM

Alchian and Demsetz’s influential explanation of the classical business firm (The American Economic Review, 1972, 62, 777–795) argues that there is need for a concentrated residual claim in the hands of a central agent, to motivate the monitoring of workers. We model monitoring as a way to transform team production from a collective action dilemma with strong free riding incentives to a productivity‐enhancing opportunity with strong private marginal incentives to contribute effort. In an experiment, we have subjects experience team production without monitoring, team production with a central monitor, and team production with peer monitoring. Then subjects vote on whether to employ the central monitor, who gets to keep a fixed share of the team output, or to rely on peer monitoring, which entails a coordination or free riding problem. Our subjects usually prefer peer monitoring but they switch to the specialist when unable to successfully self‐monitor. We provide evidence for situations in which team members resist the appointing of a central monitor and succeed in overcoming coordination and free riding problems as well as for a situation in which an Alchian–Demsetz‐like firm grows in the laboratory.     

How does homeland security affect U.S. firms' international competitiveness?

This paper frames the issue of homeland security and its relationship to the international competitiveness of U.S. firms in general. This is largely a conceptual statement, identifying the areas of national security (homeland security) that are key to business, and exploring the management concerns of business to the new threats and opportunities that have arisen.We establish the point that homeland security is a purposeful, conscious, and rational response to terrorist events that is an emergent and evolving systems phenomenon. This systems approach is an especially useful way to look at the implications of homeland security in its relation to business. We then look specifically at the kinds of costs and risks that are generated for U.S. international business (exports, imports, incoming and outgoing investments) as a result of this phenomenon. Management strategies for dealing with these costs and risks are explored for U.S. firms.Our conclusion is to demonstrate the scope of analysis that is needed to understand and to managerially cope with the homeland security problem. We show the value of using theory from various disciplines for analyzing a multi-dimensional problem like this. And finally we are able to recommend some policy dimensions for both companies and the U.S. Government toward mitigating the negative impacts of the homeland security problem.     

Computational methods for local regression

Local regression is a nonparametric method in which the regression surface is estimated by fitting parametric functions locally in the space of the predictors using weighted least squares in a moving fashion similar to the way that a time series is smoothed by moving averages. Three computational methods for local regression are presented. First, fast surface fitting and evaluation is achieved by building ak-d tree in the space of the predictors, evaluating the surface at the corners of the tree, and then interpolating elsewhere by blending functions. Second, surfaces are made conditionally parametric in any proper subset of the predictors by a simple alteration of the weighting scheme. Third degree-of-freedom quantities that would be extremely expensive to compute exactly are approximated, not by numerical methods, but through a statistical model that predicts the quantities from the trace of the hat matrix, which can be computed easily.     

跨国企业如何迎击跨文化经营的挑战

不同市场的文化差异经常困扰着企业海外经营的决策及其执行。即使企业奔赴海外开拓业务的决策是正确的，也不一定能保证获得预期的经营结果。公司本部如何选择合适的员工，派赴海外任职？从公司本部派赴海外的经理人，如何同当地员工进行有效的沟通，从而使经营决策得到贯彻落实？在海外业务运作过程中，如何利用第三方资源，减缓甚至消除不同文化所引起的企业内部冲突？这些问题，都是海外经营企业必须直面的挑战。
