There is a large literature on the role infrastructure plays in economic development, but few papers document the causal effect of infrastructure on the sustainability of natural resources. We examine the effect of the arrival of two new national highways on ground water levels in a small...

We study the returns to apprenticeship and vocational training for three early labor market outcomes all measured at age 25 for East and West German youths: non-employment (i.e., unemployment or out of the labor force), permanent fulltime employment, and wages. We find strong positive effects of...

We develop a model of firm learning in volatile markets with noisy signals and test its predictions using historical German data. Firms' forecasts improve with age. We exploit German Reunification as a natural experiment where firms in the East are treated with ignorance about the distribution...

The empirical literature is inconclusive about whether a country's democratization goes hand in hand with a reallocation of economic resources. With newly available individual-level data of former residents of the socialist German Democratic Republic (GDR), we analyse how supporters and...

The fall of the Berlin Wall in 1989 brought the end of socialism, yet pro-socialist sentiment regained momentum surprisingly quickly across Eastern Europe. Why did voters move back to an ideology that was associated with unfree elections and lackluster economic performance? This paper points to...

Motivated by the process of economic development in Eastern Germany since the German reunification we set up a dynamic macroeconomic model of a small open economy where both capital and labor are mobile and there are increasing returns to scale at the aggregate level. The model features multiple...

Over the past two decades, there have been significant changes in family dynamics and labor market interactions, with shifts in fertility, marriage, divorce, cohabitation, family labor supply, gender inequality, and childrearing. This chapter examines the impact of government policies on these...

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 both in the cross-section and over time. With the fall of the Berlin Wall and the rapid formation of a political and...

Does the Internet undermine social capital or facilitate inter-personal and civic engagement in the real world? Merging unique telecommunication data with geo-coded German individuallevel data, we investigate how broadband Internet affects several dimensions of social capital. One identification...

What are the dynamic consequences of comprehensive integration shocks? The answer to this question appears all but trivial. We set up a dynamic macroeconomic model of a small open economy where both capital and labor are mobile and there are increasing returns to scale at the aggregate level....
