Ethics Counselors as a New Priesthood

The aim of this paper is to critically evaluate the thesis that ethics counselors constitute a new priesthood in the pejorative sense of this term. In defense of the thesis, an account is given of the diverse variety of fundamental ideas about ethics or morality. The underlying argument is simply that there is such a diversity of opinion about so many fundamental issues that most ethical appraisals, especially in committees, are probably very shallow and barely warranted. Following this negative work, an attempt is made to try to find some positive benefits from the work of ethics counselors. Some potential benefits are identified, but there is a need for empirical research in order to construct a more persuasive case for such work. In the penultimate section of the paper I addressed some of my own second thoughts about the discussion and some provocative suggestions that friends gave me about earlier drafts.     

Education for the masses? The interaction between wealth,educational and political inequalities

This paper presents a simple model of distribution dynamics, in which the distributions of wealth, education and political power are circularly endogenous. Different levels of education translate into different income and wealth levels. Political power may (or may not) vary with wealth, and in turn affects decisions on the level of public expenditure on education. Since the market for education credit is imperfect, some people might need to rely on public schooling, the quality of which depends on those expenditure levels. As a result, educational opportunities differ along the wealth distribution. The dynamic system displays multiple equilibria, some of which are characterized by a vicious circle of interaction between educational, wealth and political inequalities. These particular equilibria, which are more unequal, are also shown to be inefficient in terms of aggregate output levels. Switching equilibria may be achieved through redistribution of political power.

International convergence and divergence of material input structures: an industry-level perspective

This article analyses whether international material input structures have converged or diverged over time. Pooled variances for 25 industries were obtained from OECD input–output tables in constant prices for nine countries over the period 1971–1990. It is found that high-tech industries were mainly characterized by divergence of material input structures, whereas convergence was found for many low-tech, more mature industries. In line with studies on (labour) productivity growth rates, convergence of material input structures was prevalent in the 1970s, while divergence dominated in the 1980s.     

The strategic Marshallian cross

We prove existence and uniqueness of non-autarkic equilibria in bilateral oligopoly assuming only that preferences are binormal and satisfy a weakened version of gross substitutes. We permit complete heterogeneity of preferences and our analysis exploits the fact that payoffs depend only on own strategy and two universal aggregates. This allows us to define strategic versions of supply and demand curves such that non-autarkic Nash equilibria are in 1–1 correspondence with intersections of these curves. The same approach can be used to establish comparative statics under the assumptions above. As examples, we focus on adding players and changing endowments. This competitive approach also allows us to conclude that much of conventional Marshallian analysis is robust to strategic manipulation.     

Conform or rebel: when does keeping to the rules enhance firm performance?

This paper examines whether there are economic rewards to mimicking strategic actions of other firms. The strategic behaviour we study is the formation of technology collaborations with MNEs by Indian firms. We argue that conforming to the behaviour of other firms has differential performance effects across different classes of firms and suggest that the benefits of conformity accrue more to small than large firms. To test this, we measured each Indian firm's conformity to the average tendency of other similar firms to collaborate with an MNE and then regressed its performance on conformity. Results were consistent with our expectations that small firms gain more from conformity than do their larger counterparts. Copyright © 2009 ASAC. Published by John Wiley & Sons, Ltd.

Corporate financial policies and the exchange rate regime: Evidence from Brazil

This paper analyzes the relationship between companies' financial policies and the exchange rate regime for a sample of non-financial Brazilian companies from 1996 to 2006. The adoption of a floating exchange rate regime is shown to improve the match between the currency composition of companies' assets and liabilities. The paper also shows that this reduction in companies' currency mismatches is more pronounced for companies in the highest quantile of foreign exposure; therefore the results confirm that the exchange rate regime plays an important role in the determination of companies' foreign vulnerability.     

Optimal search,learning and implementation

We characterize the incentive compatible, constrained efficient policy (“second-best”) in a dynamic matching environment, where impatient, privately informed agents arrive over time, and where the designer gradually learns about the distribution of agents? values. We also derive conditions on the learning process ensuring that the complete-information, dynamically efficient allocation of resources (“first-best”) is incentive compatible. Our analysis reveals and exploits close, formal relations between the problem of ensuring implementable allocation rules in our dynamic allocation problems with incomplete information and learning, and between the classical problem, posed by Rothschild (1974) [20], of finding optimal stopping policies for search that are characterized by a reservation price property.
