We attempt to make inferences about the elasticity of the government's demand for specific weapons by analyzing the statistical relationship between quantity and cost revisions across the population of major weapon systems, using data contained in the Pentagon's Selected Acquisition Reports. The...

We investigate whether local average treatment effects (LATE's) can be extrapolated to new settings. We extend the analysis and framework of Dehejia, Pop-Eleches, and Samii (2015), which examines the external validity of the Angrist-Evans (1998) reduced-form natural experiment of having two...

The United States became a net exporter of manufactured goods around 1910 after a dramatic surge in iron and steel exports began in the mid-1890s. This paper argues that natural resource abundance fueled the expansion of iron and steel exports in part by enabling a sharp reduction in the price...

Some world historians attach globalization big bang' significance to 1492 (Christopher Colombus stumbles on the Americas in search of spices) and 1498 (Vasco da Gama makes an end run around Africa and snatches monopoly rents away from the Arab and Venetian spice traders). Such scholars are on...

There are two contrasting views of pre-19th century trade and globalization. First, there are the world history scholars like Andre Gunder Frank who attach globalization 'big bang' significance to the dates 1492 (Christopher Colombus stumbles on the Americas in search of spices) and 1498 (Vasco...

This survey reviews the broad changes in U.S. trade policy over the course of the nation's history. Import tariffs have been the main instrument of trade policy and have had three main purposes: to raise revenue for the government, to restrict imports and protect domestic producers from foreign...

In this chapter, we describe long-run trends in global merchandise trade and immigration from 1870 to 2010. We revisit the reasons why these two forces moved largely in parallel in the decades leading up to World War I, collapsed during the interwar period, and then rebounded (but with much more...

This paper describes broad regional and temporal trends in the evolution of international trade and international factor flows between 1700 and 1870, including key differences in trade costs across space and time. We find trade links in Western Europe and the European colonies of North America...

What has driven trade booms and trade busts in the past and present? We derive a micro-founded measure of trade frictions from leading trade theories and use it to gauge the importance of bilateral trade costs in determining international trade flows. We construct a new balanced sample of...

Many papers have explored the relationship between average tariff rates and economic growth, when theory suggests that the structure of protection is what should matter. We therefore explore the relationship between economic growth and agricultural tariffs, industrial tariffs, and revenue...
