Unemployment Responses to ‘Skill‐biased’ Technology Shocks: the Role of Labour Market Policy
研究技能偏向的技术冲击（扩大劳动生产率差距）与不同政策制度相互作用，是否解释了1980-1990年代欧洲相对美国失业率上升。基于Mortensen-Pissarides模型，校准结果显示若美国采用欧洲的失业补偿和就业保护政策，其失业率也会类似上升。
Do skill-biased shocks that increase the spread of labour productivities, interacting with different policy regimes, explain the rise in unemployment in Europe relative to the United States in the 1980s and 1990s? The hypothesis is an implication of a version of the Mortensen and Pissarides (1994) model of equilibrium unemployment which allows for worker heterogeneity. A calibrated version of the model implies that a similar unemployment increase would have occurred in the United States over this period, given changes in relative productivity by education implied by observed wage changes, had unemployment compensation and employment protection policies been at European levels.
