LINKED RECURSIVE PREFERENCES AND OPTIMALITY

We study a class of optimization problems involving linked recursive preferences in a continuous‐time Brownian setting. Such links can arise when preferences depend directly on the level or volatility of wealth, in principal–agent (optimal compensation) problems with moral hazard, and when the impact of social influences on preferences is modeled via utility (and utility diffusion) externalities. We characterize the necessary first‐order conditions, which are also sufficient under additional conditions ensuring concavity. We also examine applications to optimal consumption and portfolio choice, and applications to Pareto optimal allocations.     

A Framework for Assessing Immorally Manipulative Marketing Tactics

A longstanding debate exists in both academic literature and popular culture about whether non-informative marketing tactics are manipulative. However, given that we tend to believe that some marketing tactics are manipulative and some are not, the question that marketers, their critics, and consumers need to ask themselves is that of how to actually determine whether any particular marketing tactic is manipulative and whether a given manipulative tactic is, in fact, immoral. This article proposes to operationalize criteria that can be used by marketers for making such determinations and attempts to provide some clarification toward our under- standing of the concept of manipulation and the conditions for the moral acceptability of manipulative marketing practices. It argues that a marketing tactic is manipulative if it is intended to motivate by undermining what the marketer believes is his/her audience’s normal decision-making process either by deception or by playing on a vulnerability that the marketer believes exists in his/her audience’s normal decision-making process. Such a tactic is morally objectionable on several grounds, which make it morally impermissible unless outweighed by sufficient “redemptive” moral considerations.     

Using the Capital Assets Pricing Model for risk management—A tool for multinational corporation managers

In this article, using a theoretical model and empirical analysis, we show how multinational corporations (MNCs) can utilize the fundamentals of the Capital Assets Pricing Model (CAPM) to formulate a strategic risk management in a global economy. We show that MNCs with branches all over the world, specifically those that specialize in nontradable goods (e.g., McDonald's), should consider each country's beta as the appropriate measure of the relevant risk attached to the location in the country. Finally, using data from the most recent world economic crisis (the subprime crisis), we show that during a world economic crisis the loss of growth will be significantly higher in countries with higher betas, and lower in those with lower betas. © 2011 Wiley Periodicals, Inc.

Decomposing World Income Distribution: Does The World Have A Middle Class?

Using the national income/expenditure distribution data from 111 countries, we decompose total inequality between the individuals in the world, by continents and regions. We use Yitzhaki's Gini decomposition which allows for an exact breakdown of the Gini. We find that Asia is the most heterogeneous continent; between-country inequality is much more important than inequality in incomes within countries. At the other extreme is Latin America where differences between the countries are small, but inequalities within the countries are large. Western Europe/North America is fairly homogeneous both in terms of countries' mean incomes and income differences between individuals. If we divide the world population into three groups: the rich (those with incomes greater than Italy's mean income), the poor (those with incomes less than Western countries' poverty line), and the middle class, we find that there are only 11 percent of people who are "world middle class"; 78 percent are poor, and 11 percent are rich.     

Voluntary formation of communities for the provision of public projects

In this paper we examine a group formation problem, where heterogeneous individuals partitioned themselves into communities, each choosing its own public project from the given space of feasible projects. The model is that of “horizontal product differentiation” where individuals display distinct preferences over the policy space. We consider the notion of “efficient” configuration that minimizes the total project-related costs and aggregate personalized costs of all individuals, and “sustainable” configurations, those are immune against breakaways by subgroups of individuals. Our main result is that, with a unidimensional project space and single-peaked personalized costs, every efficient partition is sustainable.     

Is higher variance necessarily bad for investment?

We consider decision-making under risk in which random events affect the value of the portfolio multiplicatively, rather than additively. In this case, a higher variability in the rate of return not only is associated with a higher risk, a bad property, but also engenders a higher expected return, a good property. As a result, certain expected utility maximizing investors, namely those with the lowest risk aversion, will prefer some portfolios with higher variances in the rate of return over others with lower ones. This is demonstrated, and implications are considered.     

Human resource practices and performance of mergers and acquisitions in Israel

An extensive body of literature has investigated financial and strategic variables as predictors of mergers and acquisitions (M&A) performance without finding clear relationships. This paper proposes a knowledge-based view of acquisitions and suggests that to enhance M&A performance acquirers must use human resources (HR) practices that develop integration capabilities during post-merger integration. The paper explains the specific effects of HR practices in M&A in Israel, a country that serves as a microcosm for developed Western countries.     

The effect of leadership style on talent retention during Merger and Acquisition integration: evidence from China

Leadership and talent retention are critical HR-related components in post-merger and acquisition (M&A) integration, but the extent to which these factors interact with each other and eventually contribute to the success of post-M&A integration is under-explored. The present study investigates the effect of leadership styles on talent retention strategies and on the effectiveness of post-M&A integration in a Chinese context. Based on in-depth examination of an M&A case study, we propose that an authoritative, coaching, task-focused and relationship-focused approach has a positive influence on talent retention and effective post-M&A integration in a Chinese context. As far as talent retention strategies are concerned, authoritative leaders use communication, whereas leaders adopting a coaching style use an incentive structure to positively influence talent retention. Furthermore, task-focused leaders use position and performance in order to identify and retain talented employees. By contrast, relationship-focused leaders emphasize the guanxi network, communication and an incentive structure in their strategies of talent retention.
