A Time‐Series Approach to Test the Productivity Bias Hypothesis in Purchasing Power Parity
用时间序列数据和协整技术重新检验生产率偏差假说，在法国、意大利、日本和英国四个国家中，至少三个国家的实证结果支持该假说。
Most previous studies have used cross-sectional data to test the "productivity bias hypothesis." They have all failed to support the hypothesis except one. In this paper, the author reexamines the hypothesis by relying upon time-series data and cointegration technique. Out of four countries (France, Italy, Japan, and the United Kingdom) for which the cointegration approach could be applied, at least three of them (Italy, Japan, and the United Kingdom) yielded empirical results supporting the productivity bias hypothesis.
