An argument in favor of long terms for central bankers

Drawing on the canonical New Keynesian model, we assess the impact of central bankers’ term duration on governments’ appointment choices. We show that longer terms induce the government to appoint more conservative central bankers, which is socially desirable.     

Organizational Performance Consequences of Age Diversity: Inspecting the Role of Diversity‐Friendly HR Policies and Top Managers’ Negative Age Stereotypes

This paper seeks to advance the diversity literature by investigating organizational performance consequences of age diversity. Drawing from social‐identity and social‐categorization theory, we theoretically argue that, in age‐diverse companies, age‐based subgrouping processes occur, favouring a shared perception of a negative age‐discrimination climate. This perceived negative age‐discrimination climate in turn negatively relates to organizational performance. As the main contribution, top managers’ negative age‐related stereotypes and diversity‐friendly HR policies are introduced as organizational‐level moderators that increase and attenuate, respectively, the social categorization processes affecting performance in age‐diverse companies. We utilized structural equation modelling (SEM) to test the proposed hypotheses using a multisource dataset comprising 147 companies. The results supported all hypotheses, indicating that low negative top managers’ age stereotypes as well as high diversity‐friendly HR policies are potential organizational factors that can prevent the negative relation of age diversity with organizational performance transmitted through the negative age‐discrimination climate. These results are discussed in light of their contribution to the diversity literature and social‐categorization theory as well as their implication for practitioners.     

Tear down this wall: on the persistence of borders in trade

Abstract Why do borders still matter for economic activity? The reunification of Germany in 1990 provides a unique natural experiment for examining the effect of political borders on trade. With the fall of the Berlin Wall and the rapid formation of a political and economic union, strong and strictly enforced administrative barriers to trade between East Germany and West Germany were eliminated completely within a very short period of time. Remarkable persistence in intra‐German trade patterns along the former East‐West border suggests that border effects are neither statistical artefacts nor driven by administrative barriers to trade, but arise from economic fundamentals.     

Optimal Social Insurance and Health Inequality

This paper integrates into public economics a biologically founded, stochastic process of individual aging. The novel approach enables us to quantitatively characterize the optimal joint design of health and retirement policy behind the veil of ignorance for today and in response to future medical progress. Calibrating our model to Germany, our analysis suggests that the current social insurance policy instruments are set close to the (constrained) socially optimal levels, given proportional contribution rates for health and pension finance, the equivalence principle in the pension system, and a common statutory retirement age. Future progress in medical technology calls for a potentially drastic increase in health spending and a higher retirement age without lowering the pension contribution rate. Interestingly, from an ex ante point of view, medical progress and higher health spending are in conflict with the goal to reduce health inequality.     

Same Same But Different: Dialects and Trade

Language is a strong and robust determinant of international trade patterns: Countries sharing a common language trade significantly more with each other than countries using different languages, holding other factors constant. In this article we present the first analysis of the effect of language on trade in an intra‐national context. Analyzing unique data for a single‐language country, Germany, we find that similarities in the local dialect have a significantly positive impact on regional trade. We interpret this finding as evidence for the trade‐promoting effect of culture, because linguistic similarities likely reflect cultural ties across regions, rather than lower costs of communication or similar institutions.
