Impulse Response Diagnostics for Priors on Parameters in Structural Vector Autoregressions
This paper proposes verifying that the prior distribution of impulse responses in structural VAR models is not unintentionally informative and discusses diagnostic tools to help practitioners ensure their priors do not unduly influence their reported conclusions.

The Contribution of Foreign Holdings of U.S. Treasury Securities to the U.S. Long-Term Interest Rate: An Empirical Investigation of the Impact of the Zero Lower Bound
This paper finds empirical evidence of a possible structural break in the relationship between the foreign holdings of U.S. Treasury securities and the U.S. long-term interest rate occurring at the time when U.S. monetary policy became constrained at the zero-lower bound (ZLB).

Xtpb: The Pooled Bewley Estimator of Long Run Relationships in Dynamic Heterogeneous Panels
This paper introduces a new Stata command, xtpb, that implements the Chudik, Pesaran and Smith (2023) Pooled Bewley (PB) estimator of long-run relationships in dynamic heterogeneous panel-data models.

When Is the Use of Gaussian-inverse Wishart-Haar Priors Appropriate?
Several recent studies have expressed concern that the Haar prior typically employed in estimating sign-identified VAR models is driving the prior about the structural impulse responses and hence their posterior. This paper provides evidence that the quantitative importance of the Haar prior for posterior inference has been overstated.

Mean Group Distributed Lag Estimation of Impulse Response Functions in Large Panels
This paper develops Mean Group Distributed Lag (MGDL) estimation of impulse responses of common shocks in large panels with one or two cross-section dimensions.

Pooled Bewley Estimator of Long-Run Relationships in Dynamic Heterogenous Panels
Using a transformation of the autoregressive distributed lag model due to Bewley, a novel pooled Bewley (PB) estimator of long-run coefficients for dynamic panels with heterogeneous short-run dynamics is proposed.

Policy impact of unexpected Fed rate movements blurred by key information cues
Unexpected Federal Reserve monetary policy moves can profoundly affect market participants, investors and the economy. The impact of policy stems not only from its direct effects—the traditional focus for economists—but also from the new information revealed about the Fed’s economic outlook.

Estimating Macroeconomic News and Surprise Shocks
This paper examines the ability of the state-of-the-art VAR approach in Kurmann and Sims (2021) to identify responses to TFP news shocks and possibly surprise shocks in theory and practice.
