The Fork Game: A Graphical Interface for Eliciting Higher-Order Risk Preferences
介绍了一种名为“分叉游戏”的图形界面，通过让参与者连接分叉管道并观察小球下落来构建复杂赌局，用于评估风险厌恶、谨慎、节制等风险偏好。
Abstract We introduce the “Fork Game,” a graphical interface designed to elicit higher-order risk preferences. In this game, participants connect forked pipes to create a final structure. A ball is then dropped into the top opening of this structure and follows a downward path, randomly turning left or right at each forked joint. This construction is effectively isomorphic to the apportionment of binary-outcome lotteries, allowing participants to construct complex gambles. Furthermore, the game is easily comprehensible, highly modular, and provides a flexible means of assessing risk aversion, prudence, temperance, and even higher-order risk preferences.
