Proposals to change the institutional features of national high courts have been on the agenda recently in the United States and Israel. Using insights about endowment effects and prospect theory from behavioral economics, we theorize about how citizens may think about benefits from high courts and how those views can influence their support for change to those institutions. Mindful of differences across these countries, we employ a comparative experimental design to explore how people think about personal and societal benefits emanating from the Israeli and United States Supreme Courts. We find interesting differences in how experimental participants think about benefits from courts and how those views shape feelings about recent proposals to alter judicial institutions in each national context.
