The principal result of this research is that the valuable skills have a negative and significant effect on alcohol abuse. We found that a higher professional level is consistent with a stronger negative relationship between earnings and alcohol-related behaviors and problems. The explanation of the result is proposed in that the pecuniary losses imposed on an individual by alcohol-related physical inability are positively conditioned by the valuable skills.
A general algorithm for the decomposition of differences between two values of an aggregate demographic measure of age and other dimensions is realized as Excel/VBA. It assumes that the aggregate measure is computed from similar matrices of discrete demographic data for two populations under comparison. The algorithm estimates the effects of replacement for each elementary cell of one matrix by the respective cell of another matrix. The replacement runs from young to old ages.
