In this paper we derive asymptotic x 2 - tests for general linear hypotheses on variance components using repeated variance components models. In two examples, the two-way nested classification model and the two-way crossed classification model with interaction, we explicitly investigate the...

This paper derives unbalanced versions of the tests statistics for ¯rst order serial correlation and random individual e®ects summarized in Sosa Escudero and Bera (2001), and updates their xttest1 routine. The derived tests statistics should be useful for applied researchers faced with the...

This paper analyses the feasibility of a monetary union within the Mercosur, focusing on cycle synchronicity. Three questions are addressed, concerning respectively the features of shocks hitting each member, the impact of exchange rate regime differences on countries’ responses and the share...
