This paper quantifies the causal effect of capital status on road network integration of U.S.micro/metropolitan statistical areas. Road network integration is defined using a class of measurements that evaluate how well a location is connected to all other locations through the National Highway...

The European Union coordinates and co-finances supra-national transport infrastructure investments in the Trans-European Transport Network (TEN-T) which consist of road, rail, airport, and port infrastructure. To the best of our knowledge, we are the first to quantify the direct and indirect...

We show that the creation of the first integrated pan-European transport network during Roman times influences economic integration over two millennia. Drawing on spatially highly disaggregated data on excavated Roman ceramics, we document that interregional trade was strongly influenced by...

We use U.S. county-level data to estimate convergence rates for 22 individual states. We find significant heterogeneity. E.g., the California estimate is 19.9 percent and the New York estimate is 3.3 percent. Convergence rates are essentially uncorrelated with income levels.

We use US county level data (3,058 observations) from 1970 to 1998 to explore the relationship between economic growth and the extent of government employment at three levels: federal, state and local. We find that increases in federal, state and local government employments are all negatively...
