Abstract

The paper examines the question of non-anonymous Growth Incidence Curves (na-GIC) from a Bayesian inferential point of view. Building on the notion of conditional quantiles of Barnett (1976. “The Ordering of Multivariate Data.” Journal of the Royal Statistical Society: Series A 139: 318–55), we show that removing the anonymity axiom leads to a complex and shaky curve that has to be smoothed, using a non-parametric approach. We opted for a Bayesian approach using Bernstein polynomials which provides confidence intervals, tests and a simple way to compare two na-GICs. The methodology is applied to examine wage dynamics in a US university with a particular attention devoted to unbundling and anti-discrimination policies. Our findings are the detection of wage scale compression for higher quantiles for all academics and an apparent pro-female wage increase compared to males. But this pro-female policy works only for academics and not for the para-academics categories created by the unbundling policy.

Keywords: academic wage formation; Bayesian inference; conditional quantiles; gender policy; non-anonymous GIC

Acknowledgment

This paper was presented at the occasion of the 12th European Seminar on Bayesian Econometrics (ESOBE 2022) held in Salzburg, Austria in September 2022 in a session dedicated to Herman van Dijk to whom the Bayesian profession owes so much. Comments by the participants of ESOBE 2022, by Neil Shephard and by Herman van Dijk are gratefully acknowledged. During the writing of the first version this paper, we have benefited from very useful conversations with Mohammad Abu-Zaineh who provided a decisive help for identifying gender and ethnicity from names. The present version benefited from the remarks of two referees and of the editor. Discussions with Luc Bauwens are also gratefully acknowledged. Of course, remaining errors are solely ours.
