【摘要】 本文对香港电视游戏节目《一掷千金》中参与者的风险决策行为进行了研究分析.发现标准的期望效用函数对于解释这些决策行为存在较大的局限性,而考虑了路径依赖的前景理论会表现较好.通过与荷兰、德国、美国节目的同类研究进行比较,本文还发现香港居民的决策行为具有一系列独特的风格.具体特点如:香港居民没有表现出明显的赌场赢利效应;其参考水平的变化对游戏价值即期变动的反应程度较低,但对其整体变化趋势特别敏感;个体之间的行为模式差异更为不明显.本文从文化差异的视角对这些特点进行了解释.更多还原

【Abstract】 We examine the risky choices of contestants in a Hong Kong TV game show where large monetary amounts are at stake. Our results reveal some difficulties for using the traditional expected utility theory to explain their behaviours and favor a path-dependent prospect theory. In particular,we find that the risk attitudes of Hong Kong contestants differ significantly from those in western countries( Netherlands,Germany,and the United States) in several aspects,including: 1) the house money effect is insignificant; 2) the reference point is sensitive to the entire change trend relative to the initial game situation; 3) individual differences are less prominent. We offer possible explanations for the cross-cultural differences.更多还原
