We analyze the interaction between risk sharing and capital accumulation in a stochastic OLG model with production. We give a complete characterization of interim Pareto optimality. Our characterization also subsumes equilibria with a PAYG social security system. In a competitive equilibrium...

Is there a role for debt beyond curing overaccumulation of capital? Does dynamic efficiency and the infeasibility of debt Ponzi schemes eliminate any Pareto-improving role for a government in a competitive economy with complete markets? Is there an optimal maturity structure of public debt?...

This paper defines and studies optimality in a dynamic stochastic economy with finitely lived agents, and investigates the optimality properties of an equilibrium with or without sequentially complete markets. Various Pareto optimality concepts are considered, including interim and ex ante...

We develop a general equilibrium stochastic OLG model with heterogenous households. Households differ with respect to their productivity. Productivity depends stochastically on parents' unobservable investment in their child's human capital and an aggregate productivity shock. We introduce a...

We propose an extended pay-as-you-go social security system that conditions pension benefits on the aggregate wage sum and on the wage of one's children. The latter increases parents' incentives to provide their children with good within-family education. However, since wages depend...

We propose an extended PAYG social security system that conditions pension benefits on the aggregate wage sum and on the wage of one’s children. The latter increases parents’ incentives to provide their children with good within-family education. However, since wages depend stochastically on...

This paper analyses a model of private unemployment insurance under limited commitment and a model of public unemployment insurance subject to moral hazard in an economy with a continuum of agents and an infinite time horizon. The dynamic and steady-state properties of the optimum private...

Le regole del regime pensionistico contributivo incentivano il proseguimento del lavoro già in corso e, alla pari di quanto avviene per le scelte di lavoro-pensionamento, trattano i casi di cumulo di pensione e reddito da lavoro in maniera finanziariamente e attuarialmente neutra. E' possibile,...

La presente nota dapprima descrive lo status quo della normativa regolante ricongiunzioni e totalizzazioni; successivamente, si evidenzia come, mentre il criterio di calcolo retributivo della pensione è inadatto a trattare con semplicità e trasparenza le situazioni di mobilità lavorativa e...

Il Decreto Legislativo del 5 Dicembre 2005, n. 252, "Disciplina delle forme pensionistiche complementari" ha introdotto in Italia il Testo Unico della Previdenza...
