The exact maximum likelihood (EML) procedure can be used as a residual-based test of the hypothesis of no cointegration against the alternative of fractional cointegration. Since the corresponding asymptotic properties have not yet been established, this paper provides simulated critical values,...

We propose a detailed Monte Carlo study of model selection criteria when the exact maximum likelihood (EML) method is used to estimate ARFIMA processes. More specifically, our object is to assess the performance of two automatic selection criteria in the presence of long-term memory: Akaike and...

According to the Fisher hypothesis, the nominal interest rate is equal to the real interest rate, plus expected inflation. Results concerning the empirical validity of this hypothesis are not unanimous. These contradictions may be due to the fact that the usual concept of cointegration is too...

The recent period has highlighted a well-known phenomenon, namely the existence of a positive bias in experts' anticipations. Literature on this subject underlines optimism in the financial analyst community. In this work, our significant contributions are twofold: we provide explanatory bias...

The aim of this paper is to study empirically the determination and the dynamic behavior of the SO2 permit prices. Previous research focused on ex-post market price analysis without taking weather conditions into account. Therefore, this study attempts to fill a gap in the literature by...

[fre] L'objet de cet article est de tester le type de la structure de dépendance des séries financières d'indices boursiers et de taux de change. A cette fin ont été mises en œuvre les procédures de détection de la mémoire longue que sont les analyses R/S et les diverses techniques...

Our object is to study the adjustment process of five European exchange rates toward their fundamentals on the 1979-1999 period. We consider two approaches, namely nonlinear cointegration and fractional cointegration, in order to discriminate between nonlinear short memory and linear long memory...

The evaluation of the reliability of analysts' earnings forecasts is an important aspect of research for different reasons: Many empirical studies employ analysts' consensus forecasts as a proxy for the market's expectations of future earnings in order to identify the unanticipated component of...

According to the permanent income hypothesis under rational expectations, variations of consumption should be larger than variations of unanticipated shocks to income. This implication of the theoretical model is not supported by the data since there seems to exist an excess smoothness of...
