The Informal Sector Wage Gap: New Evidence using Quantile Estimations on Panel Data

Bargain, Olivier; Kwenda, Prudence - HAL - 2013

We estimate the informal-formal sector pay gap throughout the conditional wage distribution using panel data from Brazil, Mexico and South Africa. We control for time-invariant unobservables and identification is stemming from inter-sector movers. We control for observables in a non-linear way...

Young-in Old-out: a new evaluation

Bia, Michella; Messe, Pierre-Jean; Leombruni, Roberto - HAL - 2010

In this paper we examine the consequences of a decrease in exits of older workers on youth employment, allowing for job-to-job áows. We distinguish between young workers with no experience and experienced workers and we consider jobs with di§erent experience requirements. Using a theoretical...

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 …

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...

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,...

Our procedure, called STIV (Self Tuning Instrumental Variables … wide classes of distributions of the data and can have finite sample validity. When the number of instruments is too large … or when one only has instruments for an endogenous regressor which are too weak, the confidence sets can have infinite …
