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.

Characterizations of bivariate distributions using concomitants of record values

In this paper, we consider a family of bivariate distributions which is a generalization of the Morgenstern family of bivariate distributions. We have derived some properties of concomitants of record values which characterize this generalized class of distributions. The role of concomitants of record values in the unique determination of the parent bivariate distribution has been established. We have also derived properties of concomitants of record values which characterize each of the following families viz Morgenstern family, bivariate Pareto family and a generalized Gumbel’s family of bivariate distributions. Some applications of the characterization results are discussed and important conclusions based on the characterization results are drawn.     

Social identity salience: Effects on identity‐based brand choices of Hispanic consumers

The purpose of this study was to examine the combinatorial effects of enduring and momentary mechanisms of cultural identity salience on identity‐based apparel brand choices of three Hispanic acculturation segments (Hispanic‐dominant, mainstream‐dominant, and balanced‐bicultural). The hypotheses were empirically tested among Hispanic students at a midwestern university in the U.S. employing a two‐session online experiment. Results revealed that the influence of cultural primes (momentary salience of the cultural identity) on subsequent brand choices of Hispanic consumers is moderated by their bidimensional acculturation (enduring salience of the cultural identity). As posited, the current study found that the same cultural primes had differential effects among the three Hispanic acculturation segments, with the largest effect size among the balanced‐bicultural segment. Specifically, the results indicated that Hispanic‐dominant and mainstream‐dominant consumers were less responsive to cultural cues in the environment and were less likely to demonstrate significant preference shifts in response to cultural primes. However, balanced‐bicultural consumers demonstrated significant shifts in their attitudes and purchase intent for Hispanic and mainstream apparel brands when exposed to cultural primes, such that their brand choices assimilated toward the primed identity. Results are discussed in the context of social identity theory, the self‐stereotyping process, cultural frame shifting, and the bidimensional acculturation model. © 2010 Wiley Periodicals, Inc.     

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.     

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).
