This paper explores the impacts on an economy of a central bank changing the size and composition of its balance sheet. One of the ways in which such asset purchases could influence prices and demand is via portfolio balance effects. We develop and calibrate a simple OLG model in which...

This paper compares the effects of conventional monetary policy on real borrowing costs with those of the unconventional measures employed after the target federal funds rate hit the zero lower bound (ZLB). For the ZLB period, we identify two policy surprises: changes in the 2-year Treasury...

The dangers of shouting ``fire'' in a crowded theater are well understood, but the dangers of rushing to the exit in the financial markets are more complex. Yet, the two events share several features, and I analyze why people crowd into theaters and trades, why they run, what determines the...

I estimate the dynamic effects of respectively traditional interest rate innovations and unconventional monetary policy actions on the Euro area economy. The results show that the Eurosystem can stimulate the economy beyond the policy rate by increasing the size of its balance sheet. The...

This paper argues that limited asset market participation is crucial in explaining U.S. macroeconomic performance and monetary policy before the 1980s, and their changes thereafter. We develop an otherwise standard sticky-price DSGE model, whereby at low enough asset market participation,...

We develop and compute a dynamic equilibrium model where economies differ on the relative efficiency of financial intermediaries and, therefore on households portfolios and currency holdings. Our model economies have some of the features of the different financial structures in countries of the...

This chapter studies optimal monetary stabilization policy in interdependent open economies, by proposing a unified analytical framework systematizing the existing literature. In the model, the combination of complete exchange-rate pass-through (`producer currency pricing') and frictionless...

We study the bond yield conundrum in a macro-finance framework. Building upon a flexible and non-structural macro-finance model, we test the hypothesis that the bond yield conundrum is connected to various sources of uncertainty in the financial markets. Moreover we explicitly test for the role...

My lessons from six years of practical policy-making include (1) being clear about and not deviating from the mandate of flexible inflation targeting (price stability and the highest sustainable employment), including keeping average inflation over a longer period on target; (2) not adding...

We provide evidence on the nature of the monetary policy transmission mechanism. To identify policy shocks in a setting with both economic and financial variables, we combine traditional monetary vector autoregression (VAR) analysis with high frequency identification (HFI) of monetary policy...
