The Effects of Expanding the Generosity of the Statutory Sickness Insurance System

This article evaluates an expansion of employer-mandated sick leave from 80% to 100% of forgone gross wages in Germany. We employ and compare parametric difference-in-difference (DID), matching DID and mixed approaches. Overall workplace absences increased by at least 10% or 1 day per worker per year. We show that taking partial compliance into account increases coefficient estimates. Further, heterogeneity ...

Parental Leave and Domestic Work of Mothers and Fathers: A Longitudinal Study of Two Reforms in West Germany

Following two parental leave reforms in West Germany, this research explores how child care and housework time changed among couples who have just had a child. The reform in 1992 extended the low paid or unpaid parental leave period, whereas the 2007 reform introduced income-dependent compensation and two "daddy months". This study contributes to the literature by examining different mechanisms on ...

Generating Skilled Self-Employment in Developing Countries: Experimental Evidence from Uganda

We study a government program in Uganda designed to help the poor and unemployed become self-employed artisans, increase incomes, and thus promote social stability. Young adults in Uganda's conflict-affected north were invited to form groups and submit grant proposals for vocational training and business start-up. Funding was randomly assigned among screened and eligible groups. Treatment groups received ...

Self-Esteem across Adulthood: The Role of Resources

It is still not well understood how and why developmental trajectories of self-esteem change, particularly in late life. We investigated the role of resources for self-esteem change across adulthood. In detail, we explored between-person differences in self-esteem levels and change in relation to resources with participants who ranged in age from 17 to 100 years. Study 1 consisted of a cross-sectional ...

A Note on Networks of Collaboration in Multi-market Oligopolies

In this note, we extend the Goyal and Joshi’s model of collaboration networks in oligopoly to multi-market situations. We examine the incentive of firms to form links and the architectures of the resulting equilibrium networks in this setting. We then present some results on efficient networks.

Effort and Performance: What Distinguishes Interacting and Noninteracting Groups from Individuals?

We study how group membership affects behavior both when group members can and cannot interact with each other. Our goal is to isolate the contrasting forces that spring from group membership: a free-riding incentive leading to reduced effort and a sense of social responsibility that increases effort. In an environment with varying task difficulty and individual decision making as the benchmark, we ...

Trade and the Environment: The Role of Firm Heterogeneity

In this paper, we derive a new effect of trade liberalization on the quality of the environment. We show that in the presence of heterogeneous firms, the aggregate volume of emissions is influenced by a reallocation effect resulting from an increase in the relative size of more productive firms. The relative importance of this reallocation effect and the scale effect well-known from the literature ...

Assessing Energy Price Induced Improvements in Efficiency of Capital in OECD Manufacturing Industries

To assess how capital stocks adapt to energy price changes, it is necessary to account for the impacts on different vintages of capital and to account separately for price-induced and autonomous improvements in the energy efficiency of capital stock. The results of econometric analysis for five manufacturing industries in 19 OECD countries between 1990 and 2005 indicate that higher energy prices resulted ...

Collusion through Joint R&D: An Empirical Assessment

This paper tests whether upstream R&D cooperation leads to downstream collusion. We show that a sufficient condition for identifying collusive behavior is a decline in the market share of RJV-participating firms. Using information from the U.S. National Cooperation Research Act, we estimate a market share equation correcting for the endogeneity of RJV participation and R&D expenditures. We find robust ...
