This paper proposes a new measure of the disincentive cost of unemployment insurance (UI): the ratio of the behavioral cost (BC) to the mechanical cost (MC) of a UI reform. This measure represents the labor supply distortion relative to the additional (mechanical) transfer from the UI reform. We show the BC/MC ratio naturally arises from a model of optimal UI and can be readily computed and compared across different types of reforms and labor market contexts. We summarize the evidence regarding the BC/MC ratio for existing studies and relate it to typical measures of employment effects of UI.
I show how, in the tradition of the dynamic labor supply literature, one can identify the moral hazard effects and liquidity effects of unemployment insurance (UI) using variations along the time profile of unemployment benefits. I use this strategy to investigate the anatomy of labor supply responses to UI. I identify the effect of benefit level and potential duration in the regression kink design using kinks in the schedule of benefits in the US. My results suggest that the response of search effort to UI benefits is driven as much by liquidity effects as by moral hazard effects. (JEL D82, J22, J65)
Abstract
Studies of moral hazard in employment-limiting social insurance programs such as Unemployment Insurance or Workers Compensation have demonstrated that higher benefits discourage work, emphasizing the price distortion inherent in benefit provision. Utilizing administrative data linking Workers’ Compensation claim records to wage records from an Unemployment Insurance payroll tax database, I explore a different explanation and implement tests for “income effects” that exploit the fact that claimants no longer experience a distorted price of non-employment after an employment-limiting benefit ends. A pair of legislative changes to a Workers’ Compensation benefit rate show little or no evidence of income effects and moderate evidence of income effects, respectively.
