We argue that greater misallocation is a key driver of the worse management practices in Mexico compared to the US. These management practices are strongly associated with higher productivity, growth, trade, and innovation. One indicator of greater misallocation in Mexico is the weaker...

How does a country's economic geography evolve along the development path? This paper documents recent employment growth in 18,961 regions in eight of the world's main economies. Overall, market potential is losing importance, and local density is gaining importance, as correlates of local...

We develop a monopolistically competitive model of trade with firm heterogeneity - in terms of productivity differences - and endogenous differences in the 'toughness' of competition across markets - in terms of the number and average productivity of competing firms. We analyze how these...

Recent literature notes that when quality is produced with fixed costs, a high quality firm can undercut its rival's prices and may find it profitable to invest more in quality as market size grows large. As a result, a market can remain concentrated even as it grows large. When quality is...

This paper characterizes the effects of market size on the size distribution of establishments for thirteen retail trade industries across 225 U.S. cities. In nearly every industry we examine, establishments are larger in larger cities, and in four industries the dispersion of establishment...

In this paper, I examine the relationship between increasing returns to scale and the geographic concentration of economic activity. Using data on U.S. counties, I estimate the structural parameters of the Krugman (1991) model of economic geography. The specification I use, which is derived from...

We examine the evolution of market potential and its role in driving economic growth over the long twentieth century. Theoretically, we exploit a structural gravity model to derive a closed-form solution for a widely-used measure of market potential. We are thus able to express market potential...

Under the Affordable Care Act, individual states have discretion in how they define coverage regions, within which insurers must charge the same premium to buyers of the same age, family structure, and smoking status. We exploit variation in these definitions to investigate whether the size of...

The US advantage in per capita output, apparent from the late 19th century, is frequently attributed to its relatively large domestic market. We construct market potential measures for the US and 26 other countries between 1880 and 1913 based on a general equilibrium model of production and...

We generalize Krugman's (1979) 'new trade' model by allowing for an explicit production chain in which a range of tasks is performed sequentially by a number of specialized teams. We demonstrate that an increase in market size induces a deeper division of labor among these teams which leads to...
