Se considera la estimacion y la inferencia de vectores autorregresivos en panel (VAP) con efectos fijos cuando la dimension temporal del panel es finita y la dimension de corte transversal es grande. Se propone un estimador de maxima verosimilitud (MV), basado en una funcion de verosimilitud...

This paper re-evaluates the key past results of unit root test, emphasizing that the use of a conventional level of significance is not in general optimal due to the test having low power. The optimal levels for popular unit root tests, chosen using the line of enlightened judgement under a...

Cointegration analysis is used to study the spot and futures price relationships for two storable commodities, corn and soybeans, and a nonstorable commodity, live hogs, over a 13-year period, 1980 to 1992. For corn and soybeans, cointegration is found in most pre-harvest contracts (July), and...

In this dissertation various tests for parameter constancy in dynamic and non-Gaussian econometric models are studied. The emphasis of this dissertation is given to the moving-estimates (ME) and recursive-estimates (RE) tests because these two tests can be easily extended to models with...
