We investigate a small open economy with constraints in both the domestic and the international credit market. The informational opaqueness of the domestic market hinders foreign lenders' activity, so that entrepreneurs face looser borrowing constraints vis-à-vis domestic financiers. However,...

From the macroeconomist's viewpoint, agent based modelling has an obvious drawback: it makes impossible to think in aggregate terms. The modeller, in fact, can reconstruct aggregate variables only “from the bottom up” by summing the levels of a myriad of individual variables. We propose a...

Recent research shows that several DSGE models provide a closer fit to the data under adaptive learning. This paper extends this research by introducing adaptive learning in the model of Krusell and Smith (1998) with uninsurable idiosyncratic risks and aggregate uncertainty. A first contribution...

Using a two-good, two-country model, we examine macroeconomic adjustment by allowing for decreasing and increasing marginal impatience (DMI and IMI). In the reference case where both countries have IMI, a negative output shock in one country lowers the interest rate and both countries' welfare...

This paper studies the impact of Federal Reserve policies that created the largest deviations from price stability during the Fed׳s first 100 years: the post-World War I deflation, the deflation of the Great Depression, the inflation of World War II, and the Great Inflation of the 1970s. In...

This note discusses Lee Ohanian׳s paper on “Monetary policy in the midst of big shocks”. In particular, it asks what would happen if assumptions are changed so inflation have redistribution effects. Evidence on nominal positions suggests that such effects can be quantitatively important.

We assess the effects of monetary policy on bank risk to verify the existence of a risk-taking channel – monetary expansions inducing banks to assume more risk. We first present VAR evidence confirming that this channel exists and is particularly significant on the bank funding side. Then, to...

We derive a New Keynesian Phillips curve under Calvo staggered pricing and endogenous market structures with Bertrand competition. Both strategic interactions and endogenous business creation strengthen the nominal rigidities. Price adjusters change their prices less when there are more direct...

The paper examines the effect of trend productivity growth on the determinacy and learnability of equilibria under alternative monetary policy rules. Under zero trend inflation we show that the economic structure is isomorphic to that of Bullard and Mitra (2002) and show that under a policy rule...
