This paper shows how changes in the volatility of the real interest rate at which small open emerging economies borrow have a quantitatively important effect on real variables like output, consumption, investment, and hours worked. To motivate our investigation, we document the strong evidence...

We formulate and estimate a tractable macroeconomic model with time-varying precautionary savings. We argue that the latter affect aggregate fluctuations via two main channels: a stabilizing aggregate supply effect working through the supply of capital; and a destabilizing aggregate demand...

This paper introduces incomplete insurance against idioyncratic labour income risk into an otherwise standard New Keynesian business cycle model with involuntary unemployment. Following an adverse monetary policy shock that lowers aggregate demand, job creation is discouraged and unemployment...

We analyze the risk-taking behavior of heterogenous intermediaries that are protected by limited liability and choose both their amount of leverage and the risk exposure of their portfolio. Due to the opacity of the financial sector, outside providers of funds cannot distinguish “prudent”...

We analyze the term structure of real interest rates in a general equilibrium model with incomplete markets and borrowing constraints. Agents are subject to both aggregate and idiosyncratic income shocks, which latter may force them into early portfolio liquidation in a bad aggregate state. We...

In this paper, we present a tractable model of time-varying precautionary saving behaviour due to changes in uninsured unemployment risk. In our model, agents facing incomplete markets and borrowing constraints respond to changes in labour market conditions by altering their buffer stock of...

The bond supply affects the yield curve through a wealth effect. We prove notably that a larger volume of titles shifts the level of the yield curve downward and increases its slope. Finally, credit constraints allow idiosyncratic and aggregate risks to interact and thus make interest rates more...

We construct a general equilibrium model with incomplete markets and borrowing constraints, in order to study the term structure of real interest rates. Agents are subject to both aggregate and idiosyncratic income shocks, which latter may force them into early portfolio liquidation whilst in...

Financial crises are often associated with an endogenous credit reversal followed by a fall in asset prices and serious disruptions in the financial sector. To account for this sequence of events, this paper constructs a model where the excessive risk-taking of portfolio investors leads to a...
