How Does the Border Affect Productivity? Evidence from American and Canadian Manufacturing Industries
研究美国和加拿大制造业的生产率波动在多大程度上是行业特有还是国家特有，发现同一行业在两国间的相关性比以往认为的更高，并确认投入使用的相似性有助于解释跨行业的生产率联动。
This study reports on how much productivity fluctuations are industry specific versus country specific. For the manufacturing industries in Canada and the United States, the correlation between cross-border pairings of the same industry are found to be more often highly correlated than previously thought. Furthermore, the study confirms earlier findings that the similarity of input use can help describe the comovement of productivity fluctuations across industries.
