Forni (2005) is the first author to study the politico-economic sustainability of pay-as-you-go social security in the canonical 2-period OLG model that uses Cobb-Douglas production and logarithmic utility under Markovian voting strategies. This paper (1) shows that equilibria can only exist if...

This paper extends the median voter result of Meltzer and Richard (1981) to the case where a labor economy has any constant returns to scale production function under quasilinear preferences with constant wage elasticity. Average productivities of the different labor inputs depend on their...

This paper constructs a model that can explain the existence of different types of immigration: skill-based, family-based and unauthorized. A social planner has preferences over redistributive transfers, the availability of a public good subject to congestion, and over the level of family-based...

The distribution of income has been shown to be approximately Pareto and there are different mechanisms proposed in the literature that can generate such distribution. This paper shows that scarcity of skills and a neoclassical production function in labor can generate an exact Pareto...
