Title: How does the border affect productivity? evidence from american and canadian manufacturing industries
Description: "This paper studies how much of productivity fluctuations are industry specific versus how much are country specific.  Using data on manufacturing industries in Canada and the United States, the paper shows that the correlation between cross-border pairings of the same industry are more often highly correlated than previously thought.  In addition, the paper confirms earlier findings that the similarity of input use can help describe the co-movement of productivity fluctuations across industries"--Federal Reserve Board web site.
