  An investigation is presented of how a comprehensive choice of five most
important measures of concordance (namely Spearman's rho, Kendall's tau, Gini's
gamma, Blomqvist's beta, and their weaker counterpart Spearman's footrule)
relate to non-exchangeability, i.e., asymmetry on copulas. Besides these
results, the method proposed also seems to be new and may serve as a raw model
for exploration of the relationship between a specific property of a copula and
some of its measures of dependence structure, or perhaps the relationship
between various measures of dependence structure themselves.
