Economists have expended considerable effort to develop economically meaningful definitions of the somewhat elusive concept of "sustainability". We relate such a definition of sustainability to well known concepts from neoclassical economics, in particular, potential Pareto improvements (in the...

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?...
