In a static setup, migration of unskilled labor may be resisted by the entire native-born population because, being relatively low earners, migrants are net beneficiaries of the fiscal system. However, the paper shows that with a pay-as-you-go pension, an important pillar of the welfare state,...

Social Security trust fund portfolio diversification to include some equities reduces the equity premium by raising the safe real interest rate. This requires changes in taxes. Under the hypothesis of constant marginal returns to risky investments, trust fund diversification lowers the price of...
