News and Uncertainty Shocks

We provide novel evidence that technological news and uncertainty shocks, identified one at a time using VAR models as in the literature, are correlated; that is, they are not truly structural. We then proceed by proposing an identification scheme to disentangle the effects of news and financial uncertainty shocks. We find that by removing uncertainty effects from news shocks, the positive responses of economic activity to news shocks are strengthened in the short term; and that the negative responses of activity to financial uncertainty shocks are deepened in the medium term as ?good ...

Macroeconomic Effects of Large-Scale Asset Purchases: New Evidence

We examine the macroeconomic effect of large-scale asset purchases (LSAPs) and forward guidance (FG) using a proxy structural VAR estimated on data through 2015, where the stance of the LSAP policy is measured using primary dealer expectations of the Federal Reserve's asset holdings. Monetary policy shocks are identified using instruments constructed from event study yield changes, and additional assumptions are employed to separately identify LSAP and FG shocks. We find that unexpected expansions in the Federal Reserve's asset holdings during the ZLB period between 2008 and 2015 had ...

Working Paper
IDENTIFICATION THROUGH HETEROGENEITY

We analyze set identification in Bayesian vector autoregressions (VARs). Because set identification can be challenging, we propose to include micro data on heterogeneous entities to sharpen inference. First, we provide conditions when imposing a simple ranking of impulse-responses sharpens inference in bivariate and trivariate VARs. Importantly; we show that this set reduction also applies to variables not subject to ranking restrictions. Second, we develop two types of inference to address recent criticism: (1) an efficient fully Bayesian algorithm based on an agnostic prior that directly ...

What Drives Inventory Accumulation? News on Rates of Return and Marginal Costs

We study the effects of news shocks on inventory accumulation in a structural VAR framework. We establish that inventories react strongly and positively to news about future increases in total factor productivity. Theory suggests that the transmission channel of news shocks to inventories works through movements in marginal costs, through movements in sales, or through interest rates. We provide evidence that changes in external and internal rates of return are central to the transmission for such news shocks. We do not find evidence of a strong substitution effect that shifts production from ...

A Flexible Finite-Horizon Identification of Technology Shocks

Recent empirical studies using in finite horizon long-run restrictions question the validity of the technology-driven real business cycle hypothesis. These results have met with their own controversy, stemming from their sensitivity to changes in model specification and the general poor performance of long-run restrictions in Monte Carlo experiments. We propose an alternative identification that maximizes the contribution of technology shocks to the forecast-error variance of labor productivity at a long, but finite horizon. In small samples, our identification outperforms its in finite ...
