The EU has argued that some agricultural subsidies are needed to provide the optimal amount of externalities (both positive and negative) produced by agriculture. The argument is that agriculture is "multifunctional" and externalities such as rural development and landscape would be...

We consider a two-period overlapping generations model in which individual voters differ not only according to age but also productivity. In such a setting, a (redistributive) Pay-As-You-Go system is politically sustainable, even when the interest rate is larger than the rate of population...

The factor of proportionality defines the type of social insurance. We adopt a two-stage political economy approach. At the first,...
