We estimate nonlinear VARs to assess to what extent fiscal spending multipliers are countercyclical in the United States. We deal with the issue of non-fundamentalness due to fiscal foresight by appealing to sums of revisions of expectations of fiscal expenditures. This measure of anticipated...

We estimate a nonlinear VAR to quantify the impact of economic policy uncertainty shocks originating in the US on the Canadian unemployment rate in booms and busts. We find strong evidence in favor of asymmetric spillover effects. Unemployment in Canada is shown to react to uncertainty shocks in...

This paper estimates a nonlinear Threshold-VAR to investigate if a Keynesian liquidity trap due to a speculative motive was in place in the U.S. Great Depression and the recent Great Recession. We find clear evidence in favor of a breakdown of the liquidity effect after an unexpected increase in...

We model U.S. post-WWII monthly data with a Smooth Transition VAR model and study the effects of an unanticipated increase in economic policy uncertainty on unemployment in recessions and expansions. We find the response of unemployment to be statistically and economically larger in recessions....

We employ real-time data available to the US monetary policy makers to estimate a Taylor rule augmented with a measure of financial uncertainty over the period 1969-2008. We find evidence in favor of a systematic response to financial uncertainty over and above that to expected inflation, output...

We employ a nonlinear VAR to document the asymmetric reaction of real economic activity to uncertainty shocks. An uncertainty shock occurring in recessions triggers an abrupt and deep drop followed by a quick rebound and a temporary overshoot. The same shock hitting in expansions induces a...

This paper investigates inflation dynamics in a panel of 20 OECD economies using an approach based on the sample autocorrelation function (ACF). We find that inflation is characterized by long-lasting fluctuations, which are similar across countries and that eventually revert to a potentially...

We investigate the dynamic properties of inflation in 20 OECD countries with a novel approach based on the autocorrelation function. We find evidence in favor of long memory and nonlinearity. Linear autoregressive models are shown to be misspecified.
