We investigate a test of equal predictive ability delineated in Giacomini and White (2006; Econometrica). In contrast to a claim made in the paper, we show that their test statistic need not be asymptotically Normal when a fixed window of observations is used to estimate model parameters. An example...

In this note we provide simulation evidence on the size and power of tests of predictive ability described in Giacomini and White (2006). Our goals are modest but non-trivial. First, we establish that there exist data generating processes that satisfy the null hypotheses of equal finite-sample...

One weakness of such tests, however, is that they fail to inform the researcher as … a small number of real exchange rates in a given panel may drive the results.

This paper builds up a simple New Keynesian model and revisits the relationship between unemployment and in ation in the long-run. It finds that when the labor market is affected by downward nominal wage rigidity, this relationship goes beyond the tradeoff between the first moments of...

This article investigates power and size of some tests for exogeneity of a binary explanatory variable in count models by conducting extensive Monte Carlo simulations. The tests under consideration are Hausman contrast tests as well as univariate Wald tests, including a new test of notably easy...
