We describe a model that integrates a multi-regional input-output model of the U.S. (50 states and the District of Columbia) with the national highway network. Interstate commodity shipments are placed on a congestible highway network. Simulations of major choke-point disruptions redirect...

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 propose a new data resource that attempts to overcome limitations of standard firm-level datasets for the UK (like the ARD/ABS) by building on administrative data covering the population of UK firms with at least one employee. We also construct a similar dataset for France and use both...

Why do cities differ so much in productivity? We document that most of the measured dispersion in productivity across US cities is spurious and reflects granularity bias: idiosyncratic heterogeneity in plant-level productivity and size, combined with finite plant counts. As a result, economies...

Larger Indian firms selling inputs to other firms tend to have more customers, tend to be used more intensively by their customers, and tend to have larger customers. Motivated by these regularities, I propose a novel empirical model of trade featuring endogenous formation of input-output...

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....

Ever since Marshall (1890) agglomeration externalities have been viewed as the key factor explaining the existence of cities and their size. However, while the various micro foundations of agglomeration externalities stress the importance of Total Factor Productivity (TFP), the empirical...

This paper explores the macroeconomic consequences of regulatory barriers in housing markets. We take a European perspective, allowing us to offer novel facts, theory, and methodology. Our focus is on Germany, a compelling case exemplifying key characteristics unique to European city systems. To...

Japan and India signed the much-awaited Comprehensive Economic Partnership Agreement (CEPA) on 16th February 2011. The CEPA will eliminate tariff on goods that account for 94% of their two way trade over ten years and will boost bilateral trade and investment. Indian exports which were subject...

For many years, Donald Shoup has been advocating cashing out free and underpriced curbside parking. How should this be implemented in practice, taking into account the stochasticity of curbside parking vacancies? Shoup has proposed setting neighborhood/period of the day-specific meter rates such...
