We study monetary optimal policy in a New Keynesian model at the zero bound interest rate where households use cash alongside house equity borrowing to conduct transactions. The amount of borrowing is limited by a collateral constraint. When either the loan to value ratio declines or house...

This paper develops a simple Dynamic Stochastic General Equilibrium (DSGE) model capable of evaluating the effect of large purchases of treasuries by central banks. The model exhibits imperfect asset substitutability between government bonds of different maturities and a feedback from the term...

We study optimal policy in a New Keynesian model at zero bound interest rate where households use cash alongside with house equity borrowing to conduct transactions. The amount of borrowing is limited by a collateral constraint. When either the loan to value ratio declines or house prices fall...

In this paper we examine the macroeconomic stability in a simple dynamic open economy model, in which monetary authorities adopt an flexible inflation-targeting regime in an environment with a liberalised capital account and flexible exchange rates. In this respect, inflation targeting is an...

The goal of this project is to deeply investigate on the main causes of the global economic and financial crises and, based on a theoretical framework, to describe a suitable optimal monetary policy. According to our empirical analysis (basically based on US data) we will prove that a mix of...

Recent developments in many industrialized countries have triggered a debate on whether monetary policy is effective when the nominal interest rate is close to zero. When the nominal interest rate hits its lower bound, the monetary authority is no longer in a position to pursue a policy of...

This paper analyzes optimal monetary policy in a standard New-Keynesian model augmented with a financial sector. The banks in the model are subject to shocks which impede their ability and willingness to produce financial assets. We show these financial market supply shocks decrease both the...

This paper incorporates limited asset markets participation in dynamic general equilibrium and develops a simple analytical framework for monetary policy analysis. Aggregate dynamics and stability properties of an otherwise standard business cycle model depend nonlinearly on the degree of asset...
