Career Concerns and Resource Allocation in Conglomerates

We investigate resource allocation decisions in conglomerateswhen managers are motivated by career concerns. When divisionalcash flows are differentially informative about managerial ability,we show that it is in the managers' interest to overallocateunobservable intangible resources to the more informative divisions.Anticipating this bias, it is optimal for the firm's ownersto also overallocate observable capital to the more informativedivisions. The model provides rationale for corporate socialismand corporate hedging. It also highlights a cost of segmentreporting and tracking stocks, namely, that they allow managersto distort their perceived ability at the expense of investors.     

Market exit of firms: Does corruption act as grease or sand?

This paper examines whether corruption acts to “grease” or “sand” firms' exit. Corruption could facilitate exit when it is a tax that distorts markets, or it might retard exit when it empowers firms to obtain undue favors. Results, using panel data across US states and considering market exit and firms' death rates as dependent variables, show that greater corruption acts as grease rather than sand in that it facilitates firms' exit/death. In other findings, larger states, greater regulations, and more unemployment contributed to exit, as did some demographic aspects. Higher state minimum wages resulted in firms' death but not exit.

Fair welfare maximization

We consider the general problem of finding fair constrained resource allocations. As a criterion for fairness we propose an inequality index, termed “fairness ratio,” the maximization of which produces Lorenz-undominated, Pareto-optimal allocations. The fairness ratio does not depend on the choice of any particular social welfare function, and hence it can be used for an a priori evaluation of any given feasible resource allocation. The fairness ratio for an allocation provides a bound on the discrepancy between this allocation and any other feasible allocation with respect to a large class of social welfare functions. We provide a simple representation of the fairness ratio as well as a general method that can be used to directly determine optimal fair allocations. For general convex environments, we provide a fundamental lower bound for the optimal fairness ratio and show that as the population size increases, the optimal fairness ratio decreases at most logarithmically in what we call the “inhomogeneity” of the problem. Our method yields a unique and “balanced” fair optimum for an important class of problems with linear budget constraints.     

An Assessment of Privatization

Mounting empirical evidence of privatization's benefits coincideswith increasing dissatisfaction and opposition among citizensand policymakers. This dissatisfaction reflects the growingquestioning of the benefits of privatization, the general downturnof global markets in the past few years and the resulting swingof the pendulum back toward increased governmental supervision,the overselling of privatization as a panacea for all economicproblems, and the concern that privatization does not producemacroeconomic and distributional gains equivalent to its microeconomicbenefits. This article takes stock of the empirical evidenceand shows that in competitive sectors privatization has beena resounding success in improving firm performance. In infrastructuresectors, privatization improves welfare, a broader and crucialobjective, when it is accompanied by proper policy and regulatoryframeworks. The article argues that despite the growing concernsprivatization should be neither abandoned nor reversed. Rather,there should be a strengthening of efforts to privatize correctly:by better tailoring privatization to local conditions, deepeningefforts to promote competition and regulatory frameworks, enforcingtransparency in sales processes, and introducing mechanismsto ensure that the poor have access to affordable essentialservices.      

A note on the consistency of maximum likelihood estimators

Abstract

A sequence of maximum likelihood estimators based on a sequence of independent but not necessarily identically distributed random variables is shown to be consistent under certain assumptions. Some examples are given to show that these assumptions are easy to verify and not very restrictive.     

R&D Strategy in International Mixed Duopoly with Research Spillovers

This paper examines the international mixed duopoly behaviour with research spillovers. Using a two‐stage game with Research and Development (R&D) and output, we investigate the effects of imperfectly appropriable R&D on optimal R&D strategies of a domestic public firm and a foreign private firm across different market interactions: (i) international R&D competition, (ii) only the foreign firm conducts R&D, (iii) only the domestic public firm conducts R&D, (iv) no firm conducts R&D, and (v) research joint venture. The results show that firms' research performances are determined by the degree of spillovers and the optimal R&D strategies involve R&D competition. Spillovers are shown to be socially beneficial and their absence can prove to be a strategic deterrent, with the public firm monopolising the market. Some of these findings contrast with the traditional models of oligopoly (with or without R&D) and mixed oligopoly (without R&D).     

Unemployment,insurance and smoking

Using recent state-level data from the United States, this article examines new influences on cigarette demand. In particular, we uniquely focus on the effects of unemployment and health insurance coverage on smoking. Results show that higher cigarette prices, a lack of health insurance and restrictions on smoking at home, all lead to reduced smoking. On the other hand, literacy, income, unemployment, workplace smoking restrictions, smokeless tobacco taxes and tobacco-producing states do not seem to have an appreciable impact. The magnitude of the price elasticity of demand is greater than that found in the pre-MSA era. Policy implications are discussed.
