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 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...

This paper examines how dollarization affects the internal wage structure in the Mexican labor market, and alters the incentives of Mexican nationals to emigrate to the United States. A simple model shows that by adopting a fixed rate regime tied directly to the U.S. dollar, Mexican policy...

Input-output tables describe the flows of goods and services between the sectors of an economy. These tables can be interpreted as weighted directed networks. At the usual level of aggregation, they contain nodes with strong self-loops and are almost completely connected. We derive two measures...

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...

We show that extrinsic or non-fundamental uncertainty influences markets in a controlled environment. This work provides the first direct evidence of sunspot equilibria. These equilibria require a common understanding of the semantics of the sunspot variable, and they appear to be sensitive to...

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...
