We study the macroeconomic effects of rational asset bubbles in an overlapping-generations economy where asset trading requires specialized intermediaries and where agents freely choose between working in the production or in the financial sector. Frictions in the market for deposits create...

We study optimal monetary policy in an analytically tractable Heterogeneous Agent New Keynesian model with rich cross-sectional heterogeneity. Optimal policy differs from that in a representative agent model because monetary policy can affect consumption inequality by reducing both idiosyncratic...

The run up to the euro currency initiated a period of capital inflows into southern European countries, i.e., Spain, Portugal, Italy and Greece. We document that those countries, and only them among OECD countries, concomitantly experienced a decline in the quality of their institutions. We...

This paper analyzes, both theoretically and empirically, the link between capital inflows and the quality of economic institutions. To this purpose, we construct a small-open economy model of the “soft budget constraint” syndrome wherein persistently cheap funding from abroad (i) raises the...

We study optimal monetary policy in a heterogeneous agent new Keynesian economy. A utilitarian planner seeks to reduce consumption inequality, in addition to stabilizing output gaps and inflation. The planner does so both by reducing income risk faced by households, and by reducing the...
