Technical Efﬁciency, Farm Size and Tropical Deforestation in the Brazilian Amazonian Forest

Marchand, Sébastien - HAL - 2011

This paper analyses the impact of farm productivity as well as farm size on deforestation in Brazil. A two step econometric approach is adopted. A bootstrapped translog stochastic frontier that is a posteriori checked for functional consistency is used in order to estimate technical efficiency...

Heterogeneity matters: labour productivity differentiated by age and skills

Roger, Muriel; Wasmer, Malgorzata - HAL - 2009

This study aims at evaluating the actual profile of marginal productivity across the age groups within the workforce. As age-productivity profile might differ between occupations, we differentiate the workforce simultaneously by skills (low-skilled, high-skilled) and by age (young, middle-aged,...

High-dimensional instrumental variables regression and confidence sets

Gautier, Eric; Tsybakov, Alexandre - HAL - 2014

We propose an instrumental variables method for inference in high-dimensional structural equations with endogenous regressors. The number of regressors K can be much larger than the sample size. A key ingredient is sparsity, i.e., the vector of coefficients has many zeros, or approximate...

Cooperation among local governments to deliver public services : a "structural" bivariate response model with fixed effects and endogenous covariate

Porto, Edoardo Di; Merlin, Vincent; Paty, Sonia - HAL - 2013

Cooperation among local governments has been encouraged to enable the aggregation of resources and improved public sector efficiency. However, if cooperation through the joint delivery of local public services is likely to be welfare enhancing for the agglomeration, but will lead to losses for...

A Test for Endogeneity in Conditional Quantiles

Kim, Tae-Hwan; Muller, Christophe - HAL - 2013

In this paper, we develop a test to detect the presence of endogeneity in conditional quantiles. Our test is a Hausman …-type test based on the distance between two estimators, of which one is consistent only under no endogeneity while the other is … consistent regardless of the presence of endogeneity in conditional quantile models. We derive the asymptotic distribution of the …

Return Migration and the Survival of Entrepreneurial Activities in Egypt

Marchetta, Francesca - HAL - 2012

The literature shows that temporary international migrants have a high propensity to opt for an entrepreneurial activity upon return, but the prospects of survival of these activities have not been explored. We address this research question using longitudinal Egyptian data. We find that...

Labour process and the division of labour, a reading

Tinel, Bruno - HAL - 2009

This article proposes an analysis of the labour process and the division of labour in capitalist production through a reading of Marx and a few others like Babbage and Braverman. The distinction between labour and labour power is used to expose the specificity of the labour process. Cooperation...
