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...

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...

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...
