Estimating VAR's sampled at mixed or irregular spaced frequencies : a Bayesian approach
Economic data are collected at various frequencies but econometric estimation typically uses the coarsest frequency. This paper develops a Gibbs sampler for estimating VAR models with mixed and irregularly sampled data. The approach allows efficient likelihood inference even with irregular and mixed frequency data. The Gibbs sampler uses simple conjugate posteriors even in high dimensional parameter spaces, avoiding a non-Gaussian likelihood surface even when the Kalman filter applies. Two applications illustrate the methodology and demonstrate efficiency gains from the mixed frequency ...

Idiosyncratic Sectoral Growth, Balanced Growth, and Sectoral Linkages
We study the growth properties of an economy where different sectors are linked by way of intermediates and potentially grow at different rates. We characterize the economy's equilibrium balanced growth path, and derive an analytical expression that summarizes how TFP growth in a given sector affects value added growth in every other sector and, therefore, aggregate GDP growth. We show in a special case that a version of Hulten's (1978) theorem, whereby the effects of changes in sector-specific productivity on GDP are entirely captured by that sector's share in GDP, also holds in growth rates ...

Optimal monetary policy regime switches
Given regime switches in the economy?s growth rate, optimal monetary policy rules may respond by switching policy parameters. These optimized parameters differ across regimes and from the optimal choice under fixed regimes, particularly in the inflation target and interest rate inertia. Optimal switching rules produce welfare gains relative to constant rules, with switches in the implicit real interest rate used for policy and the degree of interest rate inertia producing the largest gains. However, gains from switching rules decrease if the monetary authority trades-off the probability of ...

Perturbation methods for Markov-switching DSGE models
Markov-switching DSGE (MSDSGE) modeling has become a growing body of literature on economic and policy issues related to structural shifts. This paper develops a general perturbation methodology for constructing high-order approximations to the solutions of MSDSGE models. Our new method, called "the partition perturbation method," partitions the Markov-switching parameter space to keep a maximum number of time-varying parameters from perturbation. For this method to work in practice, we show how to reduce the potentially intractable problem of solving MSDSGE models to the manageable problem ...

Employment Effects of COVID-19 across States, Sectors
The COVID-19 pandemic generated sharp losses in employment in early 2020, followed by a partial but incomplete recovery that continues to this day. The effects on employment in business sectors that produce goods and those that provide services varied substantially across states. This was the case during both the initial drop and the subsequent recovery. The extent of the cross-state variation and how the variation has evolved over time has been unlike any past recessions, making the pandemic recession and recovery unprecedented in both its severity and its uneven impact.

Consumption Growth Regimes and the Post-Financial Crisis Recovery
Andrew Foerster and Jason Choi find that consumption has grown more slowly after the Great Recession due to the continued influence of persistent factors unusual to see outside recessions.
