Future generations and economic activities: The case of the social discount rate

The objective of this article is to show the difficulties economists have when they try to answer the following question: What can economists do to promote a fair and “safe” economic development? Or otherwise said: what should we do to promote more equity between generations in an environmental perspective? The purpose of this article is not to develop new tools or policies but to give an overview of some theoretical and practical problems linked to the connection between environment, intergenerational justice and economic activities. The first section focuses on the reasons for the need to develop a reflection about intergenerational equity in the economics of the environment. The second section investigates some related theoretical problems, and the third section shows the practical difficulties economists have when dealing with intertemporal economic decisions; that is, trying to take intergenerational equity into account—in particular the choice of a discount rate for public investments.     

Venture capitalists, investment appraisal and accounting information: a comparative study of the USA, UK, France, Belgium and Holland

The differences between the information used for the pre‐investment valuation and the valuation methods used by venture capital investors in five countries (USA, UK, France, Belgium and Holland) are empirically studied. The analysis is based on postal questionnaire surveys of representative samples of senior venture capitalists in each country. Differences are found, which may be attributed to the dominant corporate governance mechanism or the level of development of the venture capital market. Between‐country differences persist even after taking into account between‐country differences in the relative importance of investment stages and venture capital types. Apparently similar systems and venture capital markets place varying emphases on different valuation methods, with theoretically 'correct' methods not always being preferred in practice. The findings of the study highlight the need for venture capital firms entering non‐domestic markets to invest considerable effort in understanding the operation of these markets if they are to exploit fully their perceived competitive advantages and minimize the likelihood of repeating the problems experienced by venture capital entrants into foreign markets in the late 1980s.     

Resale Markets and the Assignment of Property Rights

The consumption of an indivisible good causes identity-dependent externalities to non-consumers. We analyse resale markets where the current owner designs the trading procedure, but cannot commit to future actions. We ask the following questions: (1) Does the identity of the initial owner matter for the determination of the final consumer? (2) Is the outcome always efficient? The major conclusion of our paper is that the irrelevance of the initial structure of property rights arises in resale processes even if there are transaction costs that hinder efficiency. This result complements the Coasian view where the irrelevance of the assignment of property rights is a consequence of efficiency.     

Recognizing Business Ethics: Practical and Ethical Challenges in Awarding Prizes for Good Corporate Behaviour

There seems to be a proliferation of prizes and rankings for ethical business over the past decade. Our principal aims in this article are twofold: to initiate an academic discussion of the epistemic and normative stakes in business-ethics competitions; and to help organizers of such competitions to think through some of these issues and the design options for dealing with them. We have been able to find no substantive literature – academic or otherwise – that addresses either of these two broad topics and audiences. Our modest aim, therefore, is to suggest an agenda of issues, and to begin to explore and analyse some of the possible arguments for and against various philosophical or practical solutions. Part I explores the challenges facing a prize-organizing committee, including problems derived from what Rawls calls the “fact of pluralism” in democratic societies (reasonable people will always disagree over some basic values, including those relevant to evaluating business practices), and epistemic issues about how we can justify qualitative judgments on the basis of incomplete quantitative data. We also try to identify risks and opportunity costs for ethics-prize granters. In Part II we spell out (a) a range of design options and (b) some advice about how any particular prize-awarding committee might select among these options to best achieve its goals (which typically involve highlighting and publicizing best practices for ethical business).     

SALARY INEQUALITY,TEAM SUCCESS,LEAGUE POLICIES,AND THE SUPERSTAR EFFECT

Using a simple model of a team's salary distribution and data from the recent Collective Bargaining Agreement between players and owners in the National Hockey League, I examine the relationship between a team's salary distribution and its winning percentage. I find that teams with higher relative payrolls and lower salary inequality have higher winning percentages. I also find evidence of a superstar effect, in that teams with a higher maximum player salary have higher winning percentages. The results are sensitive, however, to the particular measure of salary inequality used as well as the endogeneity of the salary distribution. (JEL Z22, L83, J52, C33, C26)     

REMOVING THE “VEIL OF IGNORANCE”: NONLINEARITIES IN EDUCATION EFFECTS ON GENDER WAGE INEQUALITIES

A large literature studies the mean gender wage gap in developing countries and finds mixed evidence about the role of education policies in closing gender earnings inequalities. We contribute to this literature by exploring two types of nonlinearities in wage earning regressions: (1) nonlinearities on the effects of education on expected earnings along the distribution of education endowments; and (2) heterogeneities on the contributions of education to the gender wage gap at different quantiles of the wage distribution. Our analyses provide new insights on how these nonlinear effects can be used to set up better targeted gender and development policies. (JEL I26, C14)     

Searching Pareto Optimal Solutions for the Problem of Forming and Restructuring Coalitions in Multi-Agent Systems

Coordination is one of the fundamental research issues in distributed artificial intelligence and multi-agent systems. Current multi-agent coalition formation methods present two limits: First, computation must be completely restarted when a change occurs. Second, utility functions of the agents are either global or aggregated. We present a new algorithm to cope with these limits. The first part of this paper presents a coalition formation method for multi-agent systems which finds a Pareto optimal solution without aggregating the preferences of the agents. This protocol is adapted to problems requiring coordination by coalition formation, where it is undesirable, or not possible, to aggregate the preferences of the agents. The second part of this paper proposes an extension of this method enabling dynamic restructuring of coalitions when changes occur in the system.     

The European sectoral social dialogue: questions of representation and membership

In the debates on the European social dialogue as a potential level of supranational industrial relations, the key questions of representations and mandates are often neglected. To what extent can the European sectoral social dialogue act for national constituencies across 27 Member States in the perspective of collective action by European associations? This article addresses this question by the means of three dimensions: the representation of heterogeneous members, the various degrees of national players' commitment in the European committees and finally, the definition of a common agenda among members.     

Multivariate models with dual cycles: implications for output gap and potential growth measurement

Structural time series models applied to the factor inputs of a production function often lead to small output gaps and to erratic measures of potential growth. We introduce a dual cycle model which is an extension to the multivariate trend plus cycle model with phase shifts à la Rünstler. The dual cycle model is a combination of two types of model: the trend plus cycle model and the cyclical trend model, where the cycle appears in the growth rate of a variable. This property enables hysteresis to be taken into account. Hysteresis is likely to show up in unemployment, but it can also affect the capital stock due to the existence of long investment cycles. In the proposed model, hysteresis may affect all the factor inputs of the production function and phase shifts are extended to the dual cycles. Genuine measures of potential growth can be computed that are hysteresis-free and less prone to volatility. A complementary measure of the output gap that takes hysteresis into account can be derived.     

Generalized measures of wage differentials

This paper considers measures of wage differentials not solely determined by mean comparisons but summarizing differences across complete wage distributions. The approach builds on considerations of risk or inequality aversion and on standard expected utility concepts. In an application to the gender pay gap in Luxembourg the disadvantage of women persists according to the proposed measures: lower mean wages for women are not compensated by differences in higher moments of wage distributions (e.g., by less dispersion) at least for realistic assumptions about women preferences toward risk and inequality. The paper also illustrates an original empirical model for wage distributions in the presence of covariates and under endogenous labour market participation.
