Side betting and playing the National Lottery: An exercise in policy design

This paper demonstrates a methodology for estimating the frequencies by which numbers are selected by National Lottery players by utilizing a twofold approach of a Multi-Response Non-Linear Regression model in conjunction with a suggested approximation function for number selections, which leads to an explanation of number choice in terms of the spatial effects of form design. It shows that in a marketplace, side betting is complementary with the main online draw product, and market forces produce close substitutes if side betting on the National Lottery is prohibited.
