We analyse the steady-state equilibrium dynamics of an OLG economy with a pay-as-you-go (PAYG) pension scheme that relates old-age pensions to previous earnings. Contrary to an economy where PAYG pensions depend on the earnings of those currently working, such an economy may experience complex...

We translate the property of linear risk tolerance (hyperbolical Arrow-Pratt index of risk aversion) from the expected-utility framework into a condition on the marginal rate of substitution between return and risk in the mean-variance approach.

The present paper analyzes how the welfare state, i.e., social insurance that works through redistributive taxation, should respond to increases in the skewness of the risk distribution. Income risks can be hedged either by individual self-insurance or by social insurance. It is shown that...

Within a tax competition framework, this note points out that the tax principle of Formula Apportionment may render corporate income taxation of multinational enterprises efficient even if a sales apportionment factor is not available. This is shown for constant returns to scale production...
