Using data from Labor Force Surveys (LFS), this study implements additive models to analyze the impact of schooling on wages. It also uses the Sperlich, Tjostheim and Yang (2002) test to validate the existence of interaction terms. Results confirm that the earnings-schooling relationship...

The study analyzes the performance of the Zheng test for functional form in different scenarios concerning the distribution approximation of the test statistic. We apply the test statistic for validating simple wage functions.

In this study, we compare the performance of the Zheng (1996) and Elisson-Elisson (2000) tests for omitted variable problems in parametric regression models. The study finds that the Elisson and Elisson test has better finite sample performance relative to the Zheng test. The results also...

Using a rich survey data collected in the southern part of the Philippines, this paper aims to study the effect of child labor on the child's schooling outcomes. Results indicate that the efficient allocation of time can offset the impact of an increase in the child's work hours. If child labor...
