This paper examines the macroprudential roles of bank capital regulation and monetary policy in a Dynamic Stochastic General Equilibrium model with endogenous financial frictions and a borrowing cost channel. We identify various transmission channels through which credit risk, commercial bank...

In the paper we propose an assessment of the role of financial innovation in shaping US macroeconomic dynamics. We extend an existing model by Christiano, Eichenbaum and Evans which studied the transmission of monetary policy impulses to business and corporate sector financing variables just...

I examine the transmission of expansionary U.S. monetary policy in case where developing countries-including China-peg their currencies to the dollar. I evaluate the value of the dollar peg as a fraction of consumption that households would be willing to pay for the dollar peg to remain as well...

A business cycle is, in fact, fluctuations of macroeconomic variables and gross domestic product. These fluctuations play a substantial role in any country. Prosperity and depression have been the most impressive problem in Iranian economy during the last decades so government and politicians...

Mortgage loans are a striking example of a persistent nominal rigidity. As a result, under incomplete markets, monetary policy affects decisions through the cost of new mortgage borrowing and the value of payments on outstanding debt. Observed debt levels and payment to income ratios suggest the...

The ability of financial frictions to amplify the output response of monetary policy, as in the financial accelerator model of Bernanke et al. (1999), is analyzed for a wider class of policy rules where the policy interest rate responds to both in inflation and the output gap. When policy makers...

Two recent papers (Gonçalves and Carvalho, 2009; and Brito, 2010) hold contradictory views regarding the role of inflation targeting during periods of disinflation. The first paper claims that inflation targeting reduces sacrifice ratios-i.e., the ratio of output losses to the change in trend...

We study monetary policy in a New Keynesian (NK) model with endogenous growth and knowledge spillovers external to each firm. We find the following results: (i) technology and government spending shocks have different effects on growth; (ii) disinflationary monetary policies entail positive...

We introduce endogenous growth in an otherwise standard NK model with staggered prices and wages. Some results follow: (i) monetary volatility negatively affects long-run growth; (ii) the relation between nominal volatility and growth depends on the persistence of the nominal shocks and on the...

In this paper I comment on Auray, Eyquem, and Pontineau (2012). I show that their introduction of sticky-prices into Ghironi \& Melitz (2005) framework is incorrect and generates a bias in simulation results. Additionally, I find that, by introducing sticky-prices into Ghironi \& Melitz (2005)...
