Efficiency Effects of Premium-Setting Regimes under Workers' Compensation: Canada and the United States
构建模型预测，工伤保险中按经验评级保费比统一费率更能激励安全投入，并利用加拿大安大略省林业和建筑业从统一费率转向经验评级的数据，验证了该理论对降低死亡率的显著效果。
We develop a model in which it is predicted that more resources will be devoted to safety in a workers' compensation system with experience-rated premiums than in one with flat-rated premiums. We test this model by observing the effect on fatality rates of the move from flat rating to experience rating in the forestry and construction industries of Ontario, Canada. The evidence provides strong confirmation of the theory.
