On correlated lotteries in economic applications
研究了只有少数结果的彩票之间的相关性，通过前三个单变量矩和相关系数完全刻画了两个二元彩票的联合分布，对经济建模和实验设计有参考价值。
Economic models and experiments frequently use lotteries with only a few outcomes. We study the correlation of such lotteries and discuss its relevance for economic applications. In particular, we fully characterize the joint distribution of two binary lotteries via their first three univariate moments and their correlation coefficient. As we illustrate alongside several examples, the resulting parametrization may be useful for economic modeling and experimental design.
