Production factor returns : the role of factor utilisation
Cette, Gilbert; Dromel, Nicolas L.; Lecat, Rémy; … - HAL - 2011
Short-term increasing returns to production factors are usually found in empirical studies. We argue they can be due to omitted variables, particularly the intensity of factor utilisation. Thanks to original French firm-level data (1992-2008), we show how increasing returns to scale disappear...

Impacto De Las Patentes Sobre El Crecimiento Económico: Un Modelo Panel Cointegrado [Impact of Patents on Economic Growth: A Cointegrated Panel Data Model]
Robledo, Jacobo Campo - HAL - 2012
This article presents an empirical model of non-stationary and cointegrated panel data to explain the impact of industrial property, measured by patents, on the GDP of 10 Latin America countries during the period 1990 to 2010. Apply traditional unit root tests and unit root test of art, which...

JOINT PRODUCTION WITHOUT FREE DISPOSAL: SUSTAINABLE ACTIVITY AND UNSUPPORTABLE PROCESSES
O'Connor, Martin; Andrew, Robbie - HAL - 2010
Investigations of long-run sustainability of joint ecological-economic systems highlight the pertinence of reconsidering "free disposal" assumptions that underpin Sraffian and von Neumann approaches to value and growth theory. We investigate joint-production time-paths for square systems A and B...

Endogenous Structural Change and Climate Targets : Modeling experiments with Imaclim-R
Crassous, Renaud; Hourcade, Jean Charles; Sassi, Olivier - HAL - 2006
This paper envisages endogenous technical change as resulting from the interplay between the economic growth engine, consumption, technology and localization patterns. We perform numerical simulations with the recursive dynamic general equilibrium model IMACLIM-R to study how modeling induced...

Stability tests for heterogeneous panel data
Chan, Félix; Mancini-Griffoli, Tommaso; Pauwels, Laurent L. - HAL - 2006
This paper proposes a new test for structural instability in heterogeneous panels. The test builds on the seminal work of Andrews (2003) originally developed for time series. It is robust to non-normal, heteroskedastic and serially correlated errors, and allows for the number of post break...
