Using GARCH-in-Mean models, we study the robustness of the risk-return relationship in monthly U.S. stock market returns (1928:1-2004:12) with respect to the specification of the conditional mean equation. The issue is important because in this commonly used framework, unnecessarily including an...

The approach is based on Bayesian model selection among restricted vector autoregressive (VAR) models, each of which...</p>

This paper shows that the Michigan survey data on inflation expectations is consistent with a simple sticky information model where a significant proportion of households base their inflation expectations on the past release of actual inflation rather than the rational forward-looking forecast....

Since the mid-1980s, Phillips curve forecasts of US inflation have been inferior to those of a conventional causal autoregression. However, little change in forecast accuracy is detected against the benchmark of a noncausal autoregression, more accurately characterizing US inflation dynamics.

In this paper, we propose a simulation-based method for computing point and density forecasts for univariate noncausal and non-Gaussian autoregressive processes. Numerical methods are needed for forecasting such time series because the prediction problem is generally nonlinear and therefore no...

We propose an estimation method of the new Keynesian Phillips curve (NKPC) based on a univariate noncausal autoregressive model for the inflation rate. By construction, our approach avoids a number of problems related to the GMM estimation of the NKPC. We estimate the hybrid NKPC with quarterly...
