We calibrate and simulate the model's response to `demand' shocks such as shifts in the marginal efficiency of investment, government spending shocks and news shocks. We show that investment-specific shocks can generate business cycle fluctuations that are broadly consistent with aggregate data.

Finally, following Smith (1993), we estimate the model using indirect inference methods. The empirical implications of the model both under learning and rational expectations are explored. Furthermore, we test the relative importance of various model frictions and learning dynamics in capturing...

This paper identifies a channel by which changes in the size and composition of government debt might generate macroeconomic instability in a standard New Keynesian model. The mechanism depends on failures of Ricardian equivalence because of learning dynamics. Under rational expectations, the...

Under rational expectations, monetary policy is generally highly effective in stabilizing the economy. Aggregate demand management operates through the expectations hypothesis of the term structure: Anticipated movements in future short-term interest rates control current demand. This paper...
