本文為探討人們面臨不確定的情況時,如何透過有限資訊做出最佳決策。我們以Arthur(1994)所提出的酒吧賽局去做真人實驗,研究有限空間和資源協調問題。實驗以本系林涵汝(2013)論文做衍伸,探討提供給受測者資訊增加時,對出席率的效率影響。本文與林涵汝(2013)實驗設置不同包含(1)受測者的訊息不同:林涵汝(2013)實驗只提供受測者出席時是否擁擠的資訊做為受測者下一回合是否出席的依據,而本次除了提供一樣的資訊外還提供給受測者額外資訊(2)每組組員人數不同:林涵汝(2013)實驗的每組人數都設置為5人,而本次實驗的每組人數設置為5個人和10個人,此外,我們以迴歸分析七項人格、性別來影響受測者策略選擇行為。本實驗的研究重點在於資訊和人數多寡以及人格對出席率的影響。結果研究顯示:本實驗的整體平均出席率並沒有收斂至門檻值0.6,代表組內人數少和提供給受測者資訊多,出席率較沒有效率。再來我們分析七項人格、性別對各變數(平均出席率、平均報酬、連續出席天數和行為轉換次數)的因果關係,結果性別是男生和人格越偏向有智慧,越會得到更多報酬。最後分析七項人格、性別對受測者的策略選擇影響,結果人格偏向越樂觀,越會選擇策略三。 We investigate how people make decisions with scant information when they are facing an uncertain situation. We conduct experiments with real people and observe how they coordinate in the El Farol problem. Following Lin (2013), this study investigates the attendance efficiency when providing more information to the subjects. We are different from Lin(2013) in that: 1.The information prouded to subjects is different, Lin(2013) only provided the information of crowdedness while we offer subjects additional information, 2.Lin(2013)'s groups consist of 5 subjects, while in this study, group sizes are either 5 or 10. Besides, we use regression analysis to study the relationships between personality traits, genders, working memory and the subjects behavior.The results show the average attendance rates do not converge to the threshold but are higher than that, and the smaller the group size or the more the information, the less efficient the coordination becomes . We analyze the influences of 7 personality traits and gender on average attendance rate, average payment, the continuous attendance days, and the action changing times. The results show that the male with higher wisdom got more payments. Then we analyze how personality traits and gender influence subjects strategic choices. The results show that the ones who are more optimistic will choose strategy Ⅲ. The study is from Arthur (1994)'s experiments because we don't observe convergence to 60%, but we are more efficient than Lin (2013)'s experimental.
