Does fiscal policy have large and qualitatively different effects on the economy when the nominal interest rate is zero? An emerging consensus in the New Keynesian literature is that the answer is yes. New evidence provided here suggests that the answer is often no. For a broad range of...

Does fiscal policy have qualitatively different effects on the economy in a liquidity trap? We analyze a nonlinear stochastic New Keynesian model and compare the true and loglinearized equilibria. Using the loglinearized equilibrium conditions, the answer to the above question is yes. However,...

Does fiscal policy have large and qualitatively different effects on the economy when the nominal interest rate is zero? An emerging consensus in the New Keynesian (NK) literature is that the answer to this question is yes. Evidence presented here suggests that the NK model's implications for...

Is there asymmetry in the distribution of government bond returns in developed countries? Can asymmetries be predicted using financial and macroeconomic variables? To answer the first question, we provide evidence for asymmetry in government bond returns in particular for short maturities. This...

This paper develops methodology for semiparametric panel data models in a setting where both the time series and the cross section are large. Such settings are common in finance and other areas of economics. Our model allows for heterogeneous nonparametric covariate effects as well as unobserved...

Motivated by policies implemented by some central banks in response to the financial crisis, we use a simple New Keynesian model to study a particular form of forward guidance. We assume that the policy maker makes a state-contingent commitment to hold the policy rate at the zero lower bound...

We investigate the effects of fragmentation of equity trading on the quality of the trading outcomes specifically, volatility, liquidity and volume. We use panel regression methods on a weekly dataset following the FTSE350 stocks over the period 2008-2011, which provides a lot of cross-sectional...
