In many countries elderly workers are subject to a double distortion when they consider prolonging their activity: the payroll tax and a reduction in their pension rights. It is often argued that such a double burden would not be socially desirable. We consider a setting where it would be...

It is often argued that the observed trend towards early retirement is due mainly to the implicit tax imposed on continued activity of elderly workers. We study the relevance of such a distortion in a political economy model with endogenous age of retirement. The setting is a two-period...

We consider a repeated electoral competition game between two parties, each representing a constituent with a given income level. Parties are unable to commit to any policy before the election; they choose a non-linear income tax schedule once elected. In each period, citizens cast a vote either...

We consider a two-period model. In the first period, individuals consume two goods: one is sinful and the other is not. The sin good brings pleasure but has a detrimental effect on second period health and individuals tend to underestimate this effect. In the second period, individuals can...

This paper develops a simple model of piracy to analyze its effects on prices and welfare and to study the optimal enforcement policy. A monopolist produces an information good (involving a 'large' development cost and a 'small' reproduction cost) that is sold to two groups of consumers...

This paper shows that the combination of habit formation - present consumption creating additional consumption needs in the future - and myopia may explain why some retirees are forced to 'unretire', i.e., unexpectedly return to work. It also shows that when myopia about habit formation leads to...

This paper studies the design of a nonlinear social security scheme in a society where individuals differ in two respects: productivity and degree of myopia. Myopic individuals may not save 'enough' for their retirement because their 'myopic self' emerges when labor supply and savings decisions...

This Paper studies the design of education policies in a setting of successive generations with heterogeneous individuals (high and low earning ability). Parents’ investment in education is motivated by warm-glow altruism and determines the probability that a child has high ability. Education...

Social insurance for the elderly is judged responsible for the widely observed trend towards early retirement. In a world of laissez-faire or in a first-best setting, there would be no such trend. However, when first-best instruments are not available, because health and productivity are not...

This paper studies the design of pension schemes in a society where fertility is endogenous and parents differ in their ability to raise children. In a world with perfect information, a pay-as-you-go social security system is characterized by equal pensions for all but different contributions...
