The paper comments on the economic effects of the German unification. Apart from discussing the unification in an international perspective, analyzing the distributional consequences, and pointing to structural adjustment problems, it emphasizes the distinction between the frequently cited money...

We develop a model of firm learning in volatile markets with noisy signals and test its predictions using historical data from the Ifo Institute's Business Climate Survey. We find that firms' forecasts improve as they age. We also exploit German Reunification as a natural experiment where firms...

Over the last twenty years the wage-education relationships in the US and Germany have evolved very differently, while the education composition of employment has evolved in a surprisingly parallel fashion. In this paper, we propose and test an explanation to these conflicting patterns. The...

Greater job creation in the US than in Germany has often been related to greater wage dispersion coupled with less regulated labour and product markets in the US. Based on the Comparative German American Structural Database and the International Adult Literacy Survey we find that employment of...

Urban public transit agencies spend billions of dollars each year on workers, durable capital and energy to supply transportation services. During a time of rising concern about climate change, the urban public transit sector has not significantly reduced its carbon footprint. Using data for the...

This paper investigates challenges of aging for long-term care. Our analysis proceeds in three steps. In the first step, we estimate the prospective care demand for 30 developed countries based on projected aging and disabilities among the elderly. In the second step, we outline challenges for...

This chapter provides new evidence on educational inequality and reviews the literature on the causes and consequences of unequal education. We document large achievement gaps between children from different socio-economic backgrounds, show how patterns of educational inequality vary across...

We evaluate the impact of government mandated proof of vaccination requirements for access to public venues and non-essential businesses on COVID-19 vaccine uptake. We find that the announcement of a mandate is associated with a rapid and significant surge in new vaccinations (more than 60\%...
