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.

Applications of Business Theatre in New Service Development

Applying business theatre can not only make a contribution in the context of change management, learning and development processes in companies, but also in the new service development (NSD) process. The authors show how business theatre can be applied in each step of NSD and present insights that they gained from a students’ and a research project. As service theatre addresses the “emotional side”, it is an ideal complement to a systematic NSD approach that addresses the “rational side” of a service.     

The Galileo Project put to the test of European competition and public procurement law

The following article throws some light on the (fragile) legal foundations of the Galileo Project, the European Satellite Navigation System, and gives an interpretation of the normative procurement rules of the EU. Additionally it tries to reveal the practical problems of upholding the principle of free competition and an open market in as much as the procurement of high technology concerns a highly olipolistic market.     

Shifting frontier dynamics in Latin America

The concepts of resource frontier and commodity frontier are often treated interchangeably. This article suggests the benefits of clarifying these concepts because frontiers remain important analytics for understanding drastic land‐use changes and other socio‐environmental transformations. Based on long‐term field research in different parts of South and Central America, we use frontier concepts as heuristic devices to analyze heterogeneous frontier situations and make broader generalizations. Our synchronic and diachronic analyses of frontier dynamics elucidate different frontier modalities and shifting frontier expansions. The concept of commoditizing resource frontier is introduced to explain recent frontier‐makings in Brazilian Amazonia and Cerrado and in the Nicaraguan Río San Juan. Although earlier frontier research took a short‐term time perspective and created conceptualizations based on a single modality of a particular period, our longitudinal analysis shows that drastic changes and complex overlappings are the hallmarks of frontier dynamics.     

Time-Varying Betas of German Stock Returns

The market model assumes stock returns to be a linear function of the market return. However, there is considerable evidence that the beta stability assumption commonly used when estimating the market model is invalid. In this paper we account for beta instability in German stock returns by allowing the coefficients to vary over time in estimation. For time-varying beta estimation we rely on the Flexible Least Squares approach, the Random Walk Model and Moving Window Least Squares. Due to our results time-varying estimation fits the data considerably better than time-invariant estimation and, hence, increases the efficiency of beta based risk measurement.Acknowledgements: The authors thank Stefan Mittnik, Christian Pigorsch, an anonymous referee and the editor for constructive comments.
