We show that if the central bank operates without commitment and faces constraints on its balance sheet, helicopter drops can be a useful stabilization tool during a liquidity trap. With commitment, even with balance sheet constraints, helicopter drops are irrelevant

The celebrated Taylor rule provides a simple formula that aims to capture how the central bank interest rate is adjusted as a linear function of inflation and output gap. However, the rule does not take explicitly into account the zero lower bound on the interest rate. Prior studies on interest...

This chapter examines the concept of inflation persistence in macroeconomic theory. It begins by defining persistence — emphasizing the difference between reduced-form and structural persistence. It then examines a number of empirical measures of reduced-form persistence, considering the...

In recent years, inflation in the euro area has failed to decelerate decisively while cyclical slack built up in the economy. Is this phenomenon more than a peculiarity in recent data? Is it related to structural policy settings? Econometric analysis conducted on two decades of quarterly data...

This paper uses a variety of empirical methods to examine the apparent differences in monetary policy stances as between the United States and other G7 economies, notably those in the euro area, during the period of sharp increases in oil and other commodity prices in the first half of 2008. In...

This paper derives the curvature properties of the short-run Phillips curve in a class of canonical models of price-setting frictions. Contrary to conventional thinking, the Phillips curve is asymptotically horizontal for high levels of economic activity and asymptotically vertical for low...

In contrast to the once prevailing norm of secrecy and opaqueness, transparency has now become one of the main features characterising the conduct of monetary policy. Detailed analysis of eleven OECD central banks shows that communication practices have converged markedly in the direction of...

In the past decade, a new paradigm for fiscal and monetary policy analysis has emerged, combining the canonical macro model of income and wealth inequality with the New Keynesian model. These Heterogeneous-Agent New Keynesian ("HANK") models feature new transmission channels and allow for the...

This Paper employs stochastic simulations of a small structural rational expectations model to investigate the consequences of the zero bound on nominal interest rates. We find that if the economy is subject to stochastic shocks similar in magnitude to those experienced in the US over the 1980s...

The paper considers ways of avoiding a liquidity trap and ways of getting out of one. Unless lower short nominal interest rates are associated with significantly lower interest volatility, a lower average rate of inflation, which will be associated with lower expected nominal interest rates,...
