Two questions about european unemployment

Abstract: A general equilibrium search model makes layoff costs affect the aggregate unemployment rate in ways that depend on equilibrium proportions of frictional and structural unemployment that in turn depend on the generosity of government unemployment benefits and skill losses among newly displaced workers. The model explains how, before the 1970s, lower flows into unemployment gave Europe lower unemployment rates than the United States and also how, after 1980, higher durations have kept unemployment rates in Europe persistently higher than in the United States. These outcomes arise from the way Europe's higher firing costs and more generous unemployment compensation make its unemployment rate respond to bigger skill losses among newly displaced workers. Those bigger skill losses also explain why U.S. workers have experienced more earnings volatility since 1980 and why, especially among older workers, hazard rates of gaining employment in Europe now fall sharply with increases in the duration of unemployment.

A theory of Markovian time-inconsistent stochastic control in discrete time

Abstract: We develop a theory for a general class of discrete-time stochastic control problems that, in various ways, are time-inconsistent in the sense that they do not admit a Bellman optimality principle. We attack these problems by viewing them within a game theoretic framework, and we look for subgame perfect Nash equilibrium points. For a general controlled Markov process and a fairly general objective functional, we derive an extension of the standard Bellman equation, in the form of a system of nonlinear equations, for the determination of the equilibrium strategy as well as the equilibrium value function. Most known examples of time-inconsistent stochastic control problems in the literature are easily seen to be special cases of the present theory. We also prove that for every time-inconsistent problem, there exists an associated time-consistent problem such that the optimal control and the optimal value function for the consistent problem coincide with the equilibrium control and value function, respectively for the time-inconsistent problem. To exemplify the theory, we study some concrete examples, such as hyperbolic discounting and mean–variance control.

A randomized trial of the effect of estrogen and testosterone on economic behavior

Abstract: Existing correlative evidence suggests that sex hormones may affect economic behavior such as risk taking and reciprocal fairness. To test this hypothesis we conducted a double-blind randomized study. Two-hundred healthy postmenopausal women aged 50–65 years were randomly allocated to 4 weeks of treatment with estrogen, testosterone, or placebo. At the end of the treatment period, the subjects participated in a series of economic experiments that measure altruism, reciprocal fairness, trust, trustworthiness, and risk attitudes. There was no significant effect of estrogen or testosterone on any of the studied behaviors.

The Role of Management Games in Education and Research

Abstract: This paper is intended to be a broad survey of both the present and the potential role of management games in education and research. Against a background of the history of business games, we first try to characterize the present development of these games. A few management games are described in some detail, and a number of others are mentioned only briefly. The differences between general and functional business games are discussed. Present uses of management games as a teaching device are surveyed and evaluated. Some hypotheses regarding the relations between the design and administrative characteristics of a business game and its educational properties are also formulated. What might be a major improvement over existing management games, here named the “game case,” is then suggested. In the concluding portion of this paper, the potential use of management games as a laboratory for business and social science research is surveyed. Some methodological problems which would arise from research uses of business games are also discussed.

The Effects on Sick Leave of Changes in the Sickness Insurance System

Abstract: To get a more complete picture of how labor supply is affected by economic incentives, the effects on absenteeism should be taken into account. In particular, absenteeism due to sick leave can be considerable. We examine whether the level of sick leave compensation affects sick leave behavior. Using long time series data (1955–99) for Sweden with numerous changes of the compensation level, we generally find strong effects. Reforms implying more generous compensation for sick leave tend to be associated with permanent increases in sick leave, and vice versa. These findings are reinforced in a panel study covering the 1983–91 period.
