Cet article présente un cas particulier de régression non fondée, lorsqu'une variable dépendante a un coefficient de corrélation simple proche de zéro avec deux autres variables, qui sont en revanche très corrélées entre elles. Dans ce type de régressions, les paramètres mesurant la...

This paper studies under which conditions the share of profit in value-added, financial constraints on investment and capital shortage may foster unemployment and may limit the growth of capital and/or the growth of aggregate demand, in a stock-flow consistent model. The efficiency of...

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 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...

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 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...

Using a large panel of 6,946 French manufacturing firms, this paper investigates the effect of the cost of capital and on cash flow on investment from 1990 to 1999. We compare several specifications of neo-classical demand for capital, taking into account transitory dynamics. The user cost of...

In this paper we present comparable results on the determinants of firms' investment and their link to monetary policy. The results have been obtained by the Eurosystem Monetary Transmission Network. This network has produced a series of papers in which the use of micro data permits estimating...

En modélisant un arbitrage intertemporel, le désendettement est un choix rationnel en présence d'un rendement marginal des nouveaux investissements inférieur au taux d'intérêt réel sur l'encours de la dette et supérieur au coût d'opportunité des placements des fonds internes. Dans ce...
