In 2008, the French universities evaluation agency (aeres) gave its best grade (A+) to 90 reviews in Economics and Management among 684 academic journals. This paper shows that 109 journals among 594 (18%) remaining journals with lower aeres ranking (A, B or C), have larger Social Science...

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...

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 studies how the imperfect collateral assignments of patents contribute to "deep pockets'' savings of innovative firms facing random investment opportunities in research and development (R&D) and determine the growth of their innovations, using a version of the Kiyotaki and Moore...

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...

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 studies how the imperfect collateral assignments of patents contribute to "deep pockets'' savings of innovative firms facing random investment opportunities in research and development (R&D) and determine the growth of their innovations, using a version of the Kiyotaki and Moore...

The effect of the imperfection of collateral assignments of patents on the growth of innovations and the equilibrium interest rate is studied in this paper. It leads to the following results: security interests in patents leverage the growth of innovations and the effect of a reduction of the...
