In a model with ex-ante homogenous households, earnings risk and a general earnings function, we derive the optimal linear labor tax rate and optimal linear education subsidies. The optimal income tax trades off social insurance against incentives to work and to invest in human capital....

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 analyses optimal corrective taxation and optimal income redistribution. Under general utility functions, the Pigouvian pollution tax is higher if pollution damages disproportionally hurt the poor due to equity weighting of pollution damages. Moreover, optimal pollution taxes should be...

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 formulate a two-period life-cycle model of saving, labor supply, and human capital investments when individuals differ in ability and initial wealth. Borrowing constraints prevent individuals to optimally smooth consumption over the life-cycle and to optimally invest in human capital. We show...
