The impact of protection on economic growth is one of the traditional issues in economic history, which has enjoyed a revival in recent times, with the publication of a number of comparative quantitative papers. They all share a common weakness: they measure protection with the ratio of custom...

A central prediction of a large class of theoretical models is that industry location is not necessarily uniquely determined by fundamentals. In these models, historical accident or expectations determine which of several steady-state locations is selected. Despite the theoretical prominence of...

The growth of the Italian economy over the past 150 years since unification was accompanied by a dramatic increase in the country’s integration with European and global commodity markets: foreign trade in the long run grew on average faster than the overall economy. Behind the dynamics of...

This paper develops a new insight enabling the empirical study of media capture: minority shareholders of newspapers and readers face similar risks. Both are adversely affected when corrupt insiders use the newspaper for personal profit and receive invisible revenues. This means that relevant...

We study how industry-level agglomeration economies affect government policy. Using administrative data on firm subsidies in economically lagging regions of Great Britain, we test two alternative hypotheses. Economic geography models imply that firms at an industry’s core can sustain higher...

We study the relationship between geography and growth. To do so, we first develop a dynamic spatial growth theory with realistic geography. We characterize the model and its balanced growth path and propose a methodology to analyze equilibria with different levels of migration frictions. We...

This paper examines the importance of buyer-supplier relationships, geography and the structure of the production network in firm performance. We develop a simple model where firms can outsource tasks and search for suppliers in different locations. Low search and outsourcing costs lead firms to...

The world is replete with spatial frictions. Shipping goods across cities entails trade frictions. Commuting within cities causes urban frictions. How important are these frictions in shaping the spatial economy? We develop and quantify a novel framework to address this question at three...

This paper uses data on very small UK geographies to investigate the effective size of local labor markets. Our approach treats geographic space as continuous, as opposed to a collection of non-overlapping administrative units, thus avoiding problems of mismeasurement of local labor markets...

This paper explores the interactions between external trade and regional disparities in the Italian economy since unification. It argues that the advantage of the North was initially based on natural advantage (in particular the endowment of water, intensive in silk production). From 1880...
