We examine two sets of economies, (19th century U.S. states and 20th century less developed countries) where growth rates are positively correlated with initial levels of development to document how these dynamic increasing returns operate. We find that open economies do not display a positive...

We develop a structural gravity model that introduces scale effects in bilateral trade. Scale effects and incomplete passthrough give two channels through which exchange rates have real effects on trade patterns. Estimates from Canadian provincial trade data identify these effects through their...

This study develops a model of endogenous growth based on increasing returns due to firms' technology choices. Particular attention is paid to the implications of these choices, combined with the substitution of capital for labor, on economic growth in a general equilibrium model in which the...

Household economies of scale arise when households with multiple members share public goods, making larger households better off at lower per capita expenditures. While estimates of household economies of scale are critical for measuring income and living standards, we do not know how these...

At the firm level, revenue and costs are well measured but prices and quantities are not. This paper shows that because of these data limitations estimates of returns to scale at the firm level are for the revenue function, not production function. Given this observation, the paper argues that,...

Pricing complementarities play a key role in determining the propagation of monetary disturbances in sticky price models. We propose a procedure to infer the degree of firm-level pricing complementarities in the context of a menu cost model of price adjustment using data on prices and market...

This paper develops a method for joint estimation of both the degree of internal returns to scale and the extent of external economies. We apply the method in estimating returns to scale indexes for U.S. manufacturing industries at the two-digit level. Overall, we find that only three of the...

This paper seeks to explain the U-shaped relationship between farm productivity and farm scale - the initial fall in productivity as farm size increases from its lowest levels and the continuous upward trajectory as scale increases after a threshold - observed across the world and in low-income...

This paper explores the inconsistency of common scale estimators when output is proxied by deflated sales, based on a common output deflator across firms. The problems arise when firms operate in an imperfectly competitive environment and prices differ between firms. In particular, we show that...

This paper examines the forces behind political integration through the lens of school district consolidations, which reduced the number of school districts in the United States from around 130,000 in 1930 to under 15,000 at present. Despite this large observed decline, many districts resisted...
