The effects of EMU on euro area unemployment

The author analyzes the likely impact of EMU and the associated changes in the monetary, economic, and institutional environment on European labor markets in an open economy model. He shows that in this model, the formation of a monetary union (MU) has no effect on unemployment if the participating countries were part of a fixed exchange rate regime before entering the MU and if the monetary policy of the common central bank resembles that of the former anchor bank. In addition, he discusses various cases in which this conclusion does not hold and where one can expect an impact of EMU on structural unemployment.     

A microeconometric evaluation of rehabilitation of long‐term sickness in Sweden

In this study the effects of various types of rehabilitation programmes on labour market outcomes are estimated. A main feature of this study is that it jointly evaluates multiple treatments by nonparametric matching estimators. The study is based on a large sample of persons in western Sweden who are long‐term sick and could participate in rehabilitation programmes. Our results suggest that workplace training is superior to the other rehabilitation programmes with respect to labour market outcomes, but compared to non‐participation no positive effects are found.

The Economic Impact of AIDS Treatment: Labor Supply in Western Kenya

Using longitudinal survey data collected in collaboration with a treatment program, this paper estimates the economic impacts of antiretroviral treatment. The responses in two outcomes are studied: (1) labor supply of treated adult AIDS patients; and (2) labor supply of individuals in patients' households. Within six months after treatment initiation, there is a 20 percent increase in the likelihood of the patient participating in the labor force and a 35 percent increase in weekly hours worked. Young boys in treated patients' households work significantly less after treatment initiation, while girls and adult household members do not change their labor supply.

Keeping Up With the Joneses: Analyzing the Effect of Income Inequality on Consumer Borrowing

Household debt relative to disposable income increased from 60% in 1980 to 104% at the end of 2003. ‘Buying on credit’ has become so popular that an increasing number of firms generate more profit from financing than from selling their products. In this paper, we show that rising income inequality has substantially contributed to increased consumer borrowing. Income inequality affects all components of total household debt, but the impact is strongest on non-revolving debt (installment loans), which is used to finance the purchase of consumer durables. We argue and provide evidence that the income inequality effect on consumer borrowing is a result of conspicuous consumption. Rising income inequality has forced households with smaller income gains to use debt to keep up their consumption level relative to households with larger income gains.JEL Classification: D12, G29, J31, M30     

Optimal Self-Reporting Schemes with Multiple Stages and Option Values

We consider a model of optimal law enforcement where sanctions can be reduced for self-reporting individuals. We distinguish between a first self-reporting stage before the case is investigated and a second one where the criminal is detected, but not yet convicted. Since we assume that violators have private information in both stages, fine reductions for self-reporting individuals lead ceteris paribus to a higher violation frequency. Nevertheless, we show that fine reductions should be granted in both stages. We characterize the connection between the two fine reductions in the optimal policy and relate our results to self-reporting schemes observed in reality.
