The gravity model has been widely used to infer substantial trade flow effects of institutions such as customs unions and exchange rate mechanisms. McCallum [1995] found that the US-Canada border led to trade between provinces that is a factor 22 (2,200%) times trade between states and provinces, a spectacular puzzle in light of the low formal barriers on this border. We show that the gravity model usually estimated does not correspond to the theory behind it. We solve the 'border puzzle' by applying the theory seriously. We find that national borders reduce trade between the US and Canada by about 44%, while reducing trade among other industrialized countries by about 30%. McCallum's spectacular headline number is the result of a combination of omitted variables bias and the small size of the Canadian economy. Within-Canada trade rises by a factor 6 due to the border. In contrast, within-US trade rises 25%.

Gravity with Gravitas: A Solution to the Border Puzzle

This article builds a theoretical framework to help explain governance patterns in global value chains It draws on three streams of literature ‐ transaction costs economics, production networks, and technological capability and firm-level learning ‐ to identify three variables that play a large role in determining how global value chains are governed and change These are: (1) the complexity of transactions, (2) the ability to codify transactions, and (3) the capabilities in the supply-base The theory generates five types of global value chain governance ‐ hierarchy, captive, relational, modular, and market ‐ which range from high to low levels of explicit coordination and power asymmetry The article highlights the dynamic and overlapping nature of global value chain governance through four brief industry case studies: bicycles, apparel, horticulture and electronics

The governance of global value chains

Gravity equations have been widely used to infer trade flow effects of various institutional arrangements. We show that estimated gravity equations do not have a theoretical foundation. This implies both that estimation suffers from omitted variables bias and that comparative statics analysis is unfounded. We develop a method that (i) consistently and efficiently estimates a theoretical gravity equation and (ii) correctly calculates the comparative statics of trade frictions. We apply the method to solve the famous McCallum border puzzle. Applying our method, we find that national borders reduce trade between industrialized countries by moderate amounts of 20-50 percent.

This paper develops techniques for empirically analyzing demand and supply in differentiated products markets and then applies these techniques to analyze equilibrium in the U.S. automobile industry. Our primary goal is to present a framework which enables one to obtain estimates of demand and cost parameters for a class of oligopolistic differentiated products markets. These estimates can be obtained using only widely available product-level and aggregate consumer-level data, and they are consistent with a structural model of equilibrium in an oligopolistic industry. When we apply the tech- niques developed here to the U.S. automobile market, we obtain cost and demand parameters for (essentially) all models marketed over a twenty year period.

Automobile prices in market equilibrium

This paper generates persistent real effects of a monetary disturbance in the context of staggered price setters. The model combines two related and reinforcing features: a translog demand structure and a particular input--output production structure. These features offer a rationale why a firm, when computing its own optimal contract price, is influenced by the prices set in other overlapping contracts. Practically, the two features interact in a positive manner and provide a way to generate significant endogenous persistence.

In this paper, we examine the changes in per-capita income and productivity from 1700 to modern times, and show four things: (1) that incomes per capita diverged more around the world after 1800 than before; (2) that the source of this divergence was increasing differences in the efficiency of economies; (3) that these differences in efficiency were not due to problems of poor countries in getting access to the new technologies of the Industrial Revolution; (4) that the pattern of trade from the late nineteenth century between the poor and the rich economies suggests that the problem of the poor economies was peculiarly a problem of employing labor effectively. This continues to be true today.

The latest World Bank estimates of real GDP per capita for China are significantly lower than previous ones We review possible sources of this puzzle and conclude that it reflects a combination of factors, including substitution bias in consumption, reliance on urban prices which we estimate are higher than rural ones, and the use of an expenditure-weighted rather than an output-weighted measure of GDP Taking all these together, we estimate that real per-capita GDP in China was 50% higher relative to the US in 2005 than the World Bank estimates
