From the perspective of parents, redistributive taxation can be seen as social insurance for their children, for which no private alternative exists. Because private insurance comes too late during a person's life, it cannot cover the same risks as social insurance. Empirically, 85% of social...

Just like any trade activity in well-functioning markets, migration tends to enhance the efficiency of the allocation of resources. With non-distortionary income distribution policy instruments which can compensate losers, migration generates income gains. But the gains tend to be typically...

This paper characterizes an optimal redistribution program when taxation authorities: (1)" are uninformed about individuals' value of time in both market and non-market activities observe both market-income and time allocated to market employment, and (3) are utilitarian. " Formally, the problem...

We study the immigration policy that maximizes the welfare of the native population in an economy where the government designs an optimal redistributive welfare system and supplies public goods. We show that when the government can design different tax systems for immigrants and natives, free...

This paper shows that there is a presumption that Pareto efficient taxation entails a positive tax on capital. When tax and expenditure policies can affect the market distribution of income in ways that cannot be directly offset, those effects need to be taken into account, reducing the burden...

An income tax is generally levied on both capital and labor income. The working young bears mostly the burden of the tax on labor income, whereas the retired old, who already acummulated her savings, bears the brunt of the capital income tax. Therefore, there arise two types of conflict in the...

This paper discusses how an industrialized country could defend the wages and social benefits of its unskilled workers against wage competition from immigrants. It shows that fixing social standards harms the workers and that fixing social replacement incomes implies migration into unemployment....

Migration of young workers (as distinct from retirees), even when driven in by the generosity of the welfare state, slows down the trend of increasing dependency ratio. But, even though low-skill migration improves the dependency ratio, it nevertheless burdens the welfare state. Recent studies...

The distribution of human capital and income lies at the center of a nexus of forces that shape a country's economic, institutional and technological structure. I develop here a unified model to analyze these interactions and their growth consequences. Five main issues are addressed. First, I...
