Income, leisure and proficiency: an economic study of football performance

Abstract

The influence of income, across countries, on the proficiency of leisure, as measure by international football achievement is addressed. It is widely concluded that leisure is a normal good, however; little research has been conducted on the influences of efforts to become proficient at a specific leisure activity. While the law of diminishing marginal productivity indicates that leisure proficiency will increase at a decreasing rate with increases in time allocated toward the leisure activity, the second-order effect of income on neither leisure nor leisure proficiency can theoretically be determined. To estimate these effects, an empirical examination of FIFA's World Rankings has been conducted. The results indicate that leisure proficiency on an aggregate level is positively associated with income and increases at a decreasing rate. This subsequently provides evidence that the consumption of leisure on an aggregate level also increases at a decreasing rate with increases in income.
