In this text, we review recent developments in econometrics from the viewpoint of statistical test theory. We first … identification problems may be present; (2) the construction of tests for nonparametric hypotheses, including procedures robust to … heteroskedasticity, non-normality or dynamic specification. We point out that these difficulties often originate from the ambition to …

In this paper, we analyse the behaviour of regression-based tests for seasonal unit roots when the error is … periodically heteroscedastic. We show, using the case of quaterly data to illustrate, that the limiting null distribution of tests …

In this paper we are interested in heteroskedastic regression model s, for which an appropriate bootstrap method is bootstrapping pairs, proposed by Freedman (1981). We propose an ameliorate version of it, with better numerical performance.
