This paper estimates a panel model with endogenously time-varying parameters for COVID-19 cases and deaths in U.S. states. The functional form for infections incorporates important features of epidemiological models but is flexibly parameterized to capture different trajectories of the pandemic....

Some key structural features of the U.S. economy appear to have changed in the recent decades, making the conduct of monetary policy more challenging. In particular, there is high uncertainty about the levels of the natural rate of interest and unemployment as well as about the effect of...

This paper identifies total factor productivity (TFP) news shocks using standard VAR methodology and documents a new stylized fact: in response to news about future increases in TFP, inventories rise and comove positively with other major macroeconomic aggregates. The authors show that the...

We provide a computationally simple method of including and analyzing the effects of sunspot shocks in linear rational expectations models when the equilibrium is indeterminate. Under non uniqueness sunspots can affect model dynamics through endogenous forecast errors that do not completely...

This paper considers a prototypical monetary business cycle model for the U.S. economy, in which the equilibrium is undetermined if monetary policy is "inactive". In previous multivariate studies it has been common practice to restrict parameter estimates to values for which the equilibrium is...

We study the behavior of key macroeconomic variables in the time and frequency domain. For this purpose, we decompose U.S. time series into various frequency components. This allows us to identify a set of stylized facts: GDP growth is largely a high-frequency phenomenon whereby inflation and...

We introduce inventories into a standard New Keynesian Dynamic Stochastic General Equilibrium (DSGE) model to study the effect on the design of optimal monetary policy. The possibility of inventory investment changes the transmission mechanism in the model by decoupling production from final...
