THE COST OF THE U.S. SUGAR PROGRAM REVISITED   总被引:1,自引:0,他引:1  
The article analyzes the welfare cost of the U.S. sugar program using a multimarket model of U.S. sweetener markets. The latter includes raw crops, sugar extraction and refining, and sweetener users (food-processing industries and final consumers). The authors address the industrial organization of food industries using sweeteners and treat the United States as a large importer. With the removal of the program, this article estimates (all figures in 1999 dollars) that in 1998 cane growers, sugar beet growers, and processors would have lost $307, $650, and $89 million, respectively; sweetener users would have gained $1.9 billion. World prices would have increased by 13.2%. The deadweight loss of the program is estimated at $532 million.  相似文献

What's In It for Me? CEOs Whose Firms Are Acquired   总被引:3,自引:0,他引:3  
We study benefits received by target chief executive officers(CEOs) in completed mergers and acquisitions. Certain targetCEOs negotiate large cash payments in the form of special bonusesor increased golden parachutes. These negotiated cash paymentsare positively associated with the CEO's prior excess compensationand negatively associated with the likelihood that the CEO becomesan executive of the acquiring company. Regression estimatessuggest that target shareholders receive lower acquisition premiain transactions involving extraordinary personal treatment ofthe CEO. Target CEOs experience very high turnover rates bothat the time of acquisition and, for those who remain employed,for several years thereafter.  相似文献

We analyse additive regression model fitting via the backfitting algorithm. We show that in the case of a large class of curve estimators, which includes regressograms, simple step-by-step formulae can be given for the back-fitting algorithm. The result of each cycle of the algorithm may be represented succinctly in terms of a sequence of d projections in n-dimensional space, where d is the number of design coordinates and n is sample size. It follows from our formulae that the limit of the algorithm is simply the projection of the data onto that vector space which is orthogonal to the space of all n-vectors fixed by each of the projections. The formulae also provide the convergence rate of the algorithm, the variance of the backfitting estimator, consistency of the estimator, and the relationship of the estimator to that obtained by directly minimizing mean squared distance.  相似文献

This paper develops a simple model of sequential innovations with a diversity of research lines. Competitive strategies of firms for R&D are analyzed at each stage in a sequence of innovations. We compare two alternative regimes of enforcing patent law, as a mechanism to provide adequate incentives for R&D at each stage. The regime that protects the research line gives monopoly rights to an entire line of research, hence limiting the utilization of the previous knowledge and retarding subsequent innovations. The other regime protects the product, which facilitates the use of previous knowledge at the expense of providing inadequate protection to the ideas embodied in the product, and results in underinvestment in the first stage.  相似文献

In a two-country model, we consider the implications of monetary and fiscal policy coordination for macroeconomic stabilization. We show that the optimal regime is one of monetary and fiscal policy coordination under flexible exchange rates. In the context of the European Community, this suggests that the desire to fix exchange rates may not be costless. In addition, we show that fiscal coordination requires a relatively high degree of flexibility in fiscal policy. This result suggests that limits on the flexibility of fiscal policies, as suggested in the Delors Report, may hinder macroeconomic stabilization.  相似文献

In many organizations people need to locate colleagues with knowledge and information to resolve a problem. Computer-based systems that assist users with finding such expertise are increasingly important to industrial organizations. In this paper we discuss the development of Expertise Finders suitable for use within the engineering design environment, as illustrated through the use of a scenario. A key feature of this work is that the Expertise Finder returns both recommended contacts and supporting documentation. The Expertise Finder bases its results on information held within the organization, e.g. on-line publications repositories, human resource records, and not on individually compiled Curriculum Vitaes or other forms of user-maintained records. The recommendations are presented to the user with due regard to the social context, and are supported by the documents used to make the recommendation.

Marketing decisions are particularly vulnerable to legal rulings made in both the courts and the legislatures. The effective management of those legal implications challenges the modern marketing professional. Grasping marketing’s overall legal environment, including its governing case law, regulatory statutes and future trends, is essential. This review will provide analysis of recent court cases and legislation with particular emphasis on creatively assisting the marketer’s management of the legal factor.  相似文献
