We analyze input-output matrices for a wide set of countries as weighted directed networks. These graphs contain only 47 nodes, but they are almost fully connected and many have nodes with strong self-loops. We apply two measures: random walk centrality and one based on count-betweenness. Our...

Rethinking the foundations of Heckscher-Ohlin theory when countries have different technologies, this paper shows how to make the proper adjustments for international productivity differences. The central tool is a factor conversion matrix that computes the local factor content of foreign...

We explore the relationship between input-output accounts and the national revenue function. The generalized inverse of an economy's technology matrix carries information relating changes in endowments with changes in outputs; its transpose relates output prices and factor prices. Our primary...

This paper defines a new measure of economic distance. Using consistent cross-country data, we estimate local unit costs for 35 sectors in 40 countries. The distance between two countries is the largest percentage difference in unit costs among all sectors. If all goods are traded, this distance...

Using OECD input output matrices consistently, we offer a tentative solution to the mystery of missing trade. First, we confirm the usual rejection of factor price equalization and identical technologies. Second, we develop a new technique to compute the factor content of trade when countries'...

This paper is the first application of the singular value decomposition in general equilibrium theory. Every technology matrix can be decomposed into three parts: (1) a definition of composite commodities; (2) a definition of composite factors; and (3) a simple map of composite factor prices...
