The Labour Supply Effect of the Abolition of the Earnings Rule for Older Workers in the United Kingdom
利用英国1989年取消养老金收入测试这一自然实验，发现该改革使老年男性每周工作时间增加约4小时，对女性影响较小。
High effective tax rates on work at and around state pension age deter participation. An example is the "earnings test" operating in several OECD countries. The United States abolished its test for the 65+ age group in 2000. The United Kingdom offers a "natural experiment" of this reform, as it abolished its test, known as the "earnings rule", in 1989. We examine the effect of this change, taking account of the opportunity to defer pension rights. Abolition of the rule raised working hours of older male workers by around 4 hours a week, with a lesser impact on women"s behaviour. Copyright Royal Economic Society 2002.
