An Economist’s Guide to Lottery Design
探讨了同注分彩彩票的设计问题，通过分析滚存对销量的影响来推断设计效果，发现销量与返奖率、奖金分布偏度正相关，与方差负相关，并模拟了设计变更对收入的潜在巨大影响。
This paper outlines the issues relevant to the design of pari‐mutuel lottery games and makes inferences about game design effects from estimates of how rollovers affect sales. Lottery tickets sales depend positively on the proportion of revenue returned as prizes, positively on the skewness of the prize distribution (which depends largely on how much of the prize money goes to the jackpot), and negatively on the variance in the prize distribution (which depends largely on how much goes on smaller prizes). We simulate the effects of envisaged game design changes on sales revenue and find potentially large effects.
