This paper estimates the Rybczynski equation matrix for the twenty two-digit U.S." manufacturing industries for various years between 1880 and 1987. As predicted by the standard" general equilibrium theory of interregional trade, the regression estimates show that a consistent" set of factor...

We consider a model with several regions whose technological ability and factor endowments are identical and in which transport costs between regions are non-negligible. Nonetheless, certain goods are sometimes produced by multiple firms all of which are located in the same region. These goods...

This paper surveys the theoretical and empirical literature on the relationship between the spatial distribution of economic activity and transportation costs. We develop a multi-region model of economic geography that we use to understand the general equilibrium implications of transportation...

We introduce an internal geography to the canonical model of international trade driven by comparative advantages to study the regional effects of external economic integration. The model features a dual-economy structure, in which locations near international gates specialize in export-oriented...

The history of the twentieth century can be summarized excessively briefly in five propositions: First, that the history of the twentieth century was overwhelmingly economic history. Second, that the twentieth century saw the material wealth of humankind explode beyond all previous imagining....

A period of exploration, where macroeconomics was not macroeconomics yet, but monetary theory on one side, business cycle...

This paper estimates the nature and magnitude of the local externalities from own industry scale, as envisioned by Marshall. Census panel data on individual plants in high-tech and machinery industries across up to 487 countries are utilized, to quantify the direct effects of local external...
