In this paper we use global analysis to study the welfare properties of general equilibrium economies with incomplete markets (GEI). Our main result is to show that constrained Pareto optimal equilibria are contained in a linear submanifold of the equilibrium set. This result is explicitly...

Financial innovation in an existing asset generically supports a Pareto improvement, targeting the income effect. This result, as several on taxation, owes to one unifying notion: that an intervention generically supports Pareto improvements if the implied price adjustment is sufficiently...

[...]The overall conclusion drawn from the research presented isthat monetary policy appears to have less of an impact on realactivity than it once had—but the cause of that change remainsan open issue. The conference papers explored threehypotheses en route to that finding. First, the...
