This Paper explores the effects of a menu of inter-generational fiscal policies (public debt financed by taxes, PAYG social security system and inheritance taxation) in an overlapping generations model with perfect altruism. It generalizes the model by Barro (1974) by introducing...

The dynamic inconsistency of a government's preferred policy, when it occurs, usually implies that the maximum level of welfare that can be delivered at some initial time can only be attained by constraining the economy to `low' levels in the future. In this paper, we set up a linear quadratic...

The European Monetary System (EMS) has proven to work remarkably well thus far, despite three major realignments. We make an attempt to explain the dynamic stability of the system. This attempt gives a central place to movements in desired transactions balances, or `leads and lags', as they are...

It has been recognized that the optimal strategy of a government is generally time-inconsistent: optimality requires that the government take into account expectations effects in the formulation of its policy and to ignore these effects when applying the policy. In order to analyse the problem,...

This paper sets a framework for analysing how memoryless voters may come to elect and re-elect a committed policy-maker. Policy-makers, we assume, are trusted to implement the policy that they announce ex ante (and do implement it, if elected and re-elected). Voters, however, are never bound by...

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...
