The empirical estimation of the cost-minimizing jury size and voting rule in civil trials

Since the early 1970s, the literature examining the court system has placed much emphasis on the importance of the jury size and voting rule when analyzing the jury decision-making process. In addition, researchers have also used deductive reasoning to theoretically determine the cost-minimizing jury size and voting rule with regards to Type I and Type II errors. In this paper, we take this analysis one step further by empirically estimating the cost-minimizing jury size and voting rule in civil jury trials.
