    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 ...

    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 ...

    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 ...

    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 ...

    Individual Differences in Social Comparison and Its Consequences for Life Satisfaction: Introducing a Short Scale of the Iowa-Netherlands Comparison Orientation Measure

    Research in social psychology has shown individual variation in the tendency to compare one's own opinions and abilities with those of other people, raising the question of whether social comparisons are psychological dispositions. To test the empirical validity of this proposition, Gibbons and Buunk (1999) created an instrument, the Iowa-Netherlands Comparison Orientation Measure (INCOM), that measures ...

    The Determinants of Anti-trafficking Policies: Evidence from a New Index

    We develop an index measuring the three main dimensions - prosecution, protection, and prevention - of the anti-trafficking policies of the governments of up to 180 countries over the 2000-2010 period. Overall, developed countries perform better than the rest of the world; compliance with prosecution policy is highest, while governmental efforts to protect victims of human trafficking remain weakest. ...

    On the Variability of Hybrid Discrete Choice Models

    It is well-known that not all the variables affecting decisions in a discrete choice situation are objective characteristics of the alternatives. Some of them are associated with difficult to measure attributes which may be represented as latent variables. Since this type of variables cannot be directly observed by the analyst, they must be estimated through a special model (typically a MIMIC model), ...
