We fit a Bayesian time-varying parameters structural VAR with stochastic volatility to the Federal Funds rate, GDP deflator inflation, real GDP growth, and the rate of growth of M2. We identify 4 shocks–monetary policy, demand non-policy, supply, and money demand–by imposing sign...

We show the importance of a dynamic aggregation bias in accounting for the PPP puzzle. We prove that established time-series and panel methods substantially exaggerate the persistence of real exchange rates because of heterogeneity in the dynamics of disaggregated relative prices. When...

We explore the long-run demand for M1 based on a dataset comprising 32 countries since 1851. We report six main findings: (1) Evidence of cointegration between velocity and the short rate is widespread. (2) Evidence of breaks or time-variation in cointegration relationships is weak to...

Chahrour and Jurado (2018) have shown that news and noise shocks are observationally equivalent when the econometrician only observes a fundamental process and agents' expectations about it. We show that the observational equivalence result no longer holds when the econometrician observes a...

We make two contributions to the literature exploring the role of sentiment in macroeconomic fluctuations: (I) Working with the theoretical MA representations of standard DSGE models, we show that several SVAR-based approaches to the identification of sentiment shocks are unreliable, as (e.g.)...

We make four contributions to the "news versus noise" literature: (I) We provide a new identification scheme which, in population, exactly recovers news and noise shocks. (II) We show that our scheme is not vulnerable to Chahrour and Jurado's (2018) criticism about the observational equivalence...

Based on either Monte Carlo simulations, or several examples based on actual data, I show that the ability of Johansen's tests to detect a cointegration relationship significantly deteriorates under two empirically plausible circumstances: (i ) when, in addition to a cointegration relationship,...
