Abstract

Abstract:

In a lottery with a progressive jackpot, the rollover effect refers to the increase in revenue or engagement with the jackpot size. Using a geospatial dataset of lottery ticket sales aggregated by postcode, we test two corollaries of the rollover effect. First, is the rollover effect moderated by neighborhood socioeconomic status? Second, do fluctuations in progressive-lottery sales affect the consumption of fixed-prize lottery tickets in the same neighborhoods, in line with economic notions of ‘substitution’ versus ‘complementarity’? We used data from 2012-2015 from 3 progressive-prize lotteries in Toronto (Lotto 649, Lotto Max, and Lottario), Canada from 95 forward-sortation area codes. Our regression models controlled for other cyclical fluctuations including day of week, month of year, and common paydays. There was a significant interaction between jackpot size and neighborhood SES, such lottery sales in higher SES neighborhoods were more sensitive to jackpot size. For the analysis of substitution vs complementarity, we observed that sales of fixed-prize lotteries were positively related to sales of progressive-prize lotteries (e.g. for Lotto 649; ß = 0.068, p =

Implications:

The rollover effect provides a naturalistic insight into the effects of very large jackpots on gambling behaviour, and these analyses characterize two environmental influences in how such jackpots affect gambling engagement.
