Most studies find little to no effect of classroom computers on student achievement. We suggest that this null effect may combine positive effects of computer uses without equivalently effective alternative traditional teaching practices and negative effects of uses that substitute more...

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 individual-level data, we investigate how broadband Internet affects several dimensions of social capital. One...

School choice research mostly focuses on academic outcomes. Policymakers increasingly view entrepreneurial traits as a non-cognitive outcome important for economic growth. We use international PISA-2006 student-level data to estimate the effect of private-school competition on students'...

We analyze the extent to which endogenous cultural amenities affect the spatial equilibrium share of high-human-capital employees. To overcome endogeneity, we draw on a quasi-natural experiment in German history and exploit the exogenous spatial distribution of baroque opera houses built as a...

We exploit Germany's reunification to identify how school-age education affects entrepreneurial intentions. We look at university students in reunified Germany who were born before the Iron Curtain fell. During school age, all students in the West German control group received formal and...

Ever since Sjaastad (1962), researchers have struggled to quantify the psychic costs of migration. We monetize psychic cost as the wage premium for moving to a culturally different location. We combine administrative social security panel data with a proxy for cultural difference based on...

Due to the COVID-19 crisis and the related "social distancing" measures, working from home (WfH) has suddenly become a crucial lever of economic activity. This paper combines survey and administrative data to compute measures for the feasibility of working from home among German employees....

Armed conflicts, natural disasters and infrastructure projects continue to force millions into migration. This is especially true for developing countries. After World War II, about 8 million ethnic Germans experienced a similar situation when forced to leave their homelands and settle within...

This paper analyses the effect of information disseminated by the Internet on voting behavior. We address endogeneity in Internet availability by exploiting regional and technological peculiarities of the preexisting voice telephony network that hinder the roll-out of fixed-line broadband...

We investigate whether time-persistent cultural borders impede economic exchange across regions of the same country. To measure cultural differences we evaluate, for the first time in economics, linguistic micro-data about phonological and grammatical features of German dialects. These data are...
