Defining the informal sector in terms of household enterprises, the study highlights an alternative investigative approach to the study of informal sector. It contends that one way of analysing the informal sector is to closely examine what is happening within households that drive enterprises....

This simple study uses a variant of the Hsiao et al. (2006) test to analyse the impact of bandwidth changes on model validity using actual labour force data on workers in the Philippines. The test framework is used to verify the validity of several wage specifications. Results indicate that the...

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 examines the roles of experience and education in explaining the increase in wage inequality among Philippine male workers between 1988 and 1995. It also provides a methodological approach to the analysis of wage inequality by combining non-parametric methods with semiparametric...

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.

This study is concerned with the validation of parametric functional representations of the conditional mean of wages using Philippine data. This is done in the light of studies confirming relative weaknesses associated with parametric approaches to the modelling of human capital earnings...

This study compares wage densities for female workers in the Philippines during the 1990s. Using a non-parametric consistent test developed by Li (1996), the study finds that test outcomes from various optimal bandwidth selectors are fairly comparable. On the other hand, the use of standard...

The paper conducts simple Monte Carlo simulation investigations to ascertain the finite sample properties of the Zheng test when applied to familiar specification errors in the form of omitted and irrelevant variable problems. Results indicate that the respective estimated sizes underestimate...

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.

This article provides counterfactual extensions to the Fields inequality decomposition framework and at the same time uses the nonparametric methodology in estimating bootstrap SEs and constructing confidence intervals. For methodological illustration, we decompose changes in schooling's...
