Abstract
This study compares wage densities for female workers in the Philippines during the 1990s. Using a non-parametric consistent test developed by Li (Citation1996), the study finds that test outcomes from various optimal bandwidth selectors are fairly comparable. On the other hand, the use of standard deviation as a bandwidth parameter appears to introduce misleading inferences concerning equality of densities.
