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...

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...

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...

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...

We construct, and then estimate by maximum likelihood, a tractable dynamic stochastic general equilibrium model with incomplete insurance and heterogenous agents. The key feature of our framework is that cross-sectional heterogeneity remains finite dimensional. The solution to the model thus...

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...

volatility in the real interest rates faced by a sample of four emerging small open economies: Argentina, Ecuador, Venezuela, and Brazil. We postulate a stochastic volatility process for real interest rates using T-bill rates and country spreads and estimate it with the help of the Particle...
