Nea presidential address, 1993: Why black economists?

This article looks, with humor, at the role of black economists in academia and in the economics profession.     

Herd Behaviour in Adoption of Network Technologies

In technology adoption, herd behaviour can lead to a suboptimal outcome as shown, among others, by Choi (1997). However, empirics find little support for the idea that a less efficient technology can conquer the market and lock out a more efficient one. Accordingly, we improve and generalize Choi's results, by introducing an additional source of uncertainty: the economic environment. We investigate how the economic environment can affect herding and consequently the efficiency of the technology choice. The result is a smaller adoption bias. In the limit, firms may optimally experiment with the new technology that turns out to be social welfare improving.     

Pensions reforms,workforce ageing and firm-provided welfare

This paper investigates the impact of an exogenous increase in the legal retirement age on the firms’ propensity to provide welfare services voluntarily to their employees. To this purpose we exploit a unique information derived from the Rilevazione su Imprese e Lavoro (RIL), a survey conducted in 2015 on a large and representative sample of Italian firms. Applying different regression models we show that firms which were forced to give up previously planned hirings because of the Law 201/2011 (the so-called ‘Fornero pension reform’), increased the probability of providing welfare services at workplace. By referring to the sociological, human resource management and economic literature we then argue that a sudden increase in the legal retirement age may motivate the employers to establish welfare schemes as a way to cope with an ageing workforce. Our findings also hold when propensity score matching methods are used in order to control for sample selection issues.     

Income Inequality and Macroeconomic Volatility: An Empirical Investigation

We explore the impact of macroeconomic volatility on the distribution of income. Using a cross‐section of developed and developing countries, we find that greater output volatility, defined as the standard deviation of the rate of output growth, is associated with a higher Gini coefficient and income share of the top quintile. The coefficients suggest that a strong effect on inequality resulting from a reduction in volatility: the Gini coefficient of a country like Chile would fall by 6 points if it were to reduce its volatility to the same level as Sweden or Norway. Our results seem not to be driven by the high‐inequality/high‐volatility Latin American countries.     

Who Has the Time? Community College Students’ Time-Use Response to Financial Incentives

We evaluate the effect of performance-based scholarship programs for post-secondary students on student time use and effort and whether these effects are different for students we hypothesize may be more or less responsive to incentives. To do so, we administered a time-use survey as part of a randomized experiment in which community college students in New York City were randomly assigned to be eligible for a performance-based scholarship or to a control group that was only eligible for the standard financial aid. This paper contributes to the literature by attempting to get inside the “black box” of how students respond to a monetary incentive to improve their educational attainment. We find that students eligible for a scholarship devoted more time to educational activities, increased the quality of effort toward and engagement with their studies, and allocated less time to leisure. Additional analyses suggest that students who were plausibly more myopic (place less weight on future benefits) were more responsive to the incentives, but we find no evidence that students who are arguably more time constrained were less responsive to the incentives.

     

Bridging Business and Society: The Abrinq Foundation in Brazil

This article presents the process of creation and expansion of the Fundação Abrinq pelos Direitos da Criança et do Adolescente (Abrinq Foundation for Rights of Children and Adolescents). Established in 1990 by a group of entrepreneurs from the Brazilian Toy Manufacturers’ Association (ABRINQ), the Fundação Abrinq has been successful at raising the issue of children in Brazilian society by bridging business and several other sectors of society. This article more particularly examines (1) the societal challenges related to the situation of children in Brazil; (2) the creation and development of the Abrinq Foundation; and (3) the achievements of this innovative bridging organization over 15 years.     

对丹尼尔·伯恩鲍姆的访问

茜茜:此次主题展的题目《制造世界》从何而来?丹尼尔·伯恩鲍姆:这个题目源于美国哲学家纳尔逊·古德曼(Nelson Goodman)的一本很棒的书《构造世界的多种方式》,它试图传达出一种信息而不是试图做出规定。"制造"这一理念涉及的是工作室环境下的艺术,同博物馆中的艺术有很大差别。     

Negotiating Effectively: Justice in International Environmental Negotiations

Are negotiators who rely on justice principles in the process of bargaining and drafting agreements more—or rather less—effective than others? This article examines whether adherence to principles of procedural and distributive justice in negotiations contributes to more effective results, with a focus on international environmental negotiations. Effectiveness is defined in terms of the extent of agreement (among parties and on issues), time to reach agreement, and comprehensiveness of the agreement. A set of hypotheses is evaluated on a selection of bilateral and multilateral cases of environmental negotiations, using statistical methods. The analyses reveal that adherence to principles of procedural justice contributes to more effective results in multilateral environmental negotiations. These principles are found to hinder effectiveness in the bilateral cases. On the other hand, adherence to principles of distributive justice is only moderately related to effectiveness in both the bilateral and multilateral cases.
