Innovation, nature of investment and divergent growth paths: an explanatory model

Flacher, David; Lorenzi, Jean-Hervé; Villemeur, Alain - HAL - 2005

The principle of conditional convergence, in growth theory, fails to explain growth paths that are durably divergent … among countries having similar structural characteristics (same rates of investment, of capitaldepreciation, of demographic … growth, and similar access to technologies and resources...). Our research models the reasons of these divergencesby making …

Existence of pure Nash equilibria in discontinuous and non quasiconcave games

Bich, Philippe - HAL - 2009

In a recent but well known paper, Reny has proved the existence of Nash equilibria for compact and quasiconcave games, with possibly discontinuous payoff functions. In this paper, we prove that the quasiconcavity assumption in Reny's theorem can be weakened : we introduce a measure allowing to...

An answer to a question of herings et al.

Bich, Philippe - HAL - 2008

One answers to an open question of Herings et al. (2008), by proving that their fixed point theorem for discontinuous functions works for mappings defined on convex compact subset of a Euclidean space, and not only polytopes. This rests on a fixed point result of Toussaint

Some fixed point theorems for discontinuous mappings

Bich, Philippe - HAL - 2006

This paper provides a fixed point theorem à la Schauder, where the mappings considered are possibly discontinuous. Our main result generalizes and unifies several well-known results.

An answer to a question of herings et al

Bich, Philippe - HAL - 2008

One answers to an open question of Herings et al. (2008), by proving that their fixed point theorem for discontinuous functions works for mappings defined on convex compact subset of $\R^n$, and not only polytopes. This fixed point theorem can be applied to the problem of Nash equilibrium...

A new cosmology of risks and crises time for a radical shift in paradigm and practice

Lagadec, Patrick - HAL - 2008

Crisis management theory and practice was in the main elaborated in the late 70s and 80s and developed and implemented in the 90s. We now have a rich knowledge of crisis intelligence and best practices. But, even if we can be proud of that advance, a further challenge remains: crises in the 21st...

Does soft information matter for financial analysts' forecasts? A gravity model approach

Breton, Régis; Galanti, Sébastien; Hurlin, Christophe; … - HAL - 2011

We study whether the financial analysts' concern to maintain good relationships with firms' managers in order to preserve their access to 'soft' qualitative information entice them to issue pessimistic or optimistic forecasts. We use a gravity model approach to firmsanalysts relationships and...

Does the firm-analyst relationship matter in explaining analysts' earnings forecast errors?

Breton, Régis; Galanti, Sébastien; Hurlin, Christophe; … - HAL - 2013

We study whether financial analysts' concern for preserving good relationships with firms' managers motivates them to issue pessimistic or optimistic forecasts. Based on a dataset of one-yearahead EPS forecasts issued by 4 648 analysts concerning 241 French firms (1997-2007), we regress the...

Immigration, growth and unemployment: Panel VAR evidence from OECD countries

BOUBTANE, Ekrame; COULIBALY, Dramane; Rault, C. - HAL - 2013

This paper examines empirically the interaction between immigration and host country economic conditions. We employ a panel VAR techniques to use a large annual dataset on 22 OECD countries over the period 1987-2009. The VAR approach allows to addresses the endogeneity problem by allowing the...
