We assess whether global social welfare has improved in the last decades despite (or because of) the substantial increase in global population. We use for this purpose a relatively unknown but simple and attractive social evaluation approach called critical-level generalized utilitarianism...

This paper examines optimal redistribution in a model with high- and low-skilled individuals with heterogeneous tastes for labor. We compare the extent to which optimal policies based on different normative criteria obey the principles of compensation (for differential skills) and responsibility...

We analyze tax policies in an intertemporal economy with endogenous fertility under critical-level utilitarianism, both from a positive and a normative standpoint. On the positive side, we analyze the effects of a change in the tax on capital income and on fertility, both separately and combined...

In this paper, we introduce a new family of rank-dependent measures of inequality and social welfare consistent with the equality of opportunity (EOp) principle. The proposed framework can be used to measure long-term as well as short-term EOp, depending on whether we let permanent income or...

This paper examines whether myopia (misperception of the old age dependency risk) and private insurance market loading costs can justify public long-term care (LTC) provision and/or the subsidization of private insurance. Individuals differ in dependency risk, productivity and degree of risk...

Within the framework of spatial tax competition with cross-border shopping, we examine the choice of tax method between ad valorem tax and unit (specific) tax. This study shows that governments endogenously choose the ad valorem tax method not because of a classic welfare reason, but because it...

In this paper, I characterize the optimal redistribution policy in a simple life-cycle framework with both an intensive and an extensive margin of labor supply. The extensive margin corresponds to the choice of a retirement age. The optimal allocation cannot be implemented in a decentralized...

We build an equilibrium model of prostitution where clients and sex workers choose to demand and supply sex under three legal regimes: prohibition, regulation and laissez-faire. The key feature is the endogenous evolution of the risk as a consequence of policy changes. We calibrate the model to...

Displaced workers often experience large losses in earnings even a long time after reemployment. Training programs during unemployment mitigate these losses but also affect the unemployed's willingness to search. This paper analyzes how mandatory training programs affect the optimal design of...
