Several tests for heteroskedasticity in linear regression models are examined. Asymptoticrobustness to heterokurticity …, nonnormality and skewness is discussed. The finite sample eliability of asymptotically valid tests is investigated using Monte …

In this paper, we match firm data to work history files in order to simultaneously estimate the wage and employment duration processes of a longitudinal sample of two million French workers employed in roughly one million firms and followed over twenty years. We use the particular structure of...

In this paper, we match firm data to individual work history files in order to simultaneously estimate the wage and employment duration processes of a longitudinal sample of two million French workers employed in roughly one million firms and followed over twenty years. The particular structure...

In this paper we suggest simple moment-based estimators to deal with unobserved heterogeneity in a special class of nonlinear regression models that includes as main particular cases exponential models for nonnegative responses and logit and complementary loglog models for fractional responses....
