This paper shows that a multiple regression with two highly correlated explanatory variables, both of them with a near zero correlation with the dependent variable may correspond to a spurious regression or to a homeostatic model, with estimates highly sensible to outliers. The regression method...

This paper demonstates the existence of a finite set of equilibria in the case of the indeterminacy of linear rational expectations models. The number of equilibria corresponds to the number of ways to select n eigenvectors among a larger set of eigenvectors related to stable eigenvalues. A...

This paper studies how credit rationing affects endogenous growth when capital and debt are related to the firm´s internal net worth, taken as collateral. The accumulation of firm´s net worth determines the growth rate of capital and the growth rate of the economy. The relation between growth...

En 2008, l'agence d'évaluation de la recherche et de l'enseignement supérieur (AERES) a attribué sa meilleure note (A+) à 90 revues en économie et gestion parmi 684 revues. Cet article montre que 109 revues parmi les 594 (18%) revues classées A, B ou C par l'AERES ont des facteurs d'impact...

This paper proposes a new pre-test estimator of panel data models including time invariant variables based upon the Mundlak-Krishnakumar estimator and an "unrestricted” Hausman-Taylor estimator. The paper evaluates the biases of currently used restricted estimators, omitting the...

The bargaining power of international banks is currently still very high as compared to what it was at the time of the Bretton Woods conference. As a consequence, systemic financial crises are likely to remain recurrent phenomena with large effects on macroeconomic aggregates. Mainstream...

Explanatory variables with simple correlation coefficients with the dependent variable below 0.1 in absolute value (such as aid with economic growth) may have very large and statistically significant estimated parameters in multiple regressions, which are unifortunately "outliers driven" or...

This paper demonstates the existence of a finite set of equilibria in the case of the indeterminacy of linear rational expectations models. The number of equilibria corresponds to the number of ways to select n eigenvectors among a larger set of eigenvectors related to stable eigenvalues. A...

Cet article montre qu'une régression multiple avec deux variables explicatives très corrélées entre elles et dont les corrélations simples avec une variable dépendante sont quasi nulles peuvent correspondre soit à une régression fallacieuse, soit à un modèle homéostatique très...

This paper investigates the identification, the determinacy and the stability of ad hoc, "quasi-optimal" and optimal policy rules augmented with financial stability indicators (such as asset prices deviations from their fundamental values) and minimizing the volatility of the policy interest...
