This paper presents new evidence on the effects of retirement benefits on labor force participation decisions. The analysis is based on a mandated rule for employer-provided retirement benefits in Austria that creates discontinuities in the incentives for workers to delay retirement. We present...

We derive a general optimal income tax formula when individuals respond along both the intensive and extensive margins and when income effects can prevail. Individuals are heterogeneous across two dimensions: their skill and their disutility of participation. Preferences over consumption and...

This paper characterizes the optimal redistributive tax schedule in a matching unemployment framework where (voluntary) nonparticipation and (involuntary) unemployment are endogenous. The optimal employment tax rate is given by an inverse employment elasticity rule. This rule depends on the...

This paper extends the Diamond (1980) model with labor unions to study optimal income taxation and to analyze whether unions can be desirable for income redistribution. Unions bargain with firms over wages in each sector and firms unilaterally determine employment. Unions raise the efficiency...

This paper bolsters Prescott's (2004) claim that high taxes are responsible for lacklustre labor market performance in continental European countries. We develop a lifecycle model with endogenous skill formation, endogenous labor supply, and endogenous retirement. Labor taxation distorts not...

We characterize optimal redistributive taxation when individuals are heterogeneous in their skills and their values of non-market activities. Search-matching frictions on the labor markets create unemployment. Wages, labor demand and participation are endogenous. Average tax rates are increasing...
