本文用實驗法探討灌溉水源 (以 water queues 的形式) 的事前分配 (用 bidding) vs 事後水源拍賣,對生產決策 (種高/低水量需求作物) 之影響。以2007-08 英國 Exeter 大學學生和巴西農業區半工半讀的學生或公務員為受試者,實驗結果證明,事前的 water queues 制度,相對於事後的 spot market 分配水源的制度,有助於提昇效率。
其原因主要是在,決策者面對 environmental and strategic 兩種不確定之下, 可以利用先知道對手對環境不確定之選擇,用來當做生產決策協調之依據。
[引文] The advantage of resource queues over spot markets concerns two types of uncertainty, environmental and strategic.
(較早寫的)
此篇用經濟實驗法, 研究農民在灌溉用水不確定下之決策; 投入種子、肥料、整地的成本, 但利潤取決於不確定供水。在環境不確定 (雨量多寡) 前,先以 bidding (water queues) 決定用水優先序,可做為投入種植決策之協調機制,使得在事前 water queues 制度下, 比雨量確定後才拍賣決定水權制度更有效率。

Farmers have to make key decisions, such as which crops to plant or whether to prepare the soil, before knowing how much water they will get. They face losses if they make costly decisions but do not receive water, and they may forego profits if they receive water without being prepared. We consider the coordination of farmers’ decisions, such as which crops to plant or whether to prepare the soil when farmers must divide an uncertain water supply. We compare ex-ante queues (pre-decision) to
an ex-post spot market (post-decision & post-rain) in experiments in rural Brazil and a university in England. Queues have greater coordination success than does the spot market.

本文回顧到這篇:
The most relevant experiment of which we are aware is that of Lefebvre et al. (2012), which studies profits with security-differentiated water rights (mimicking the essence of a queue) versus non-differentiated, equal share rights. The differentiated rights are seen to have profit and risk-management benefits relative to the non-differentiated rights.

Production economics in the presence of risk

Shankar, S. (2012). Production economics in the presence of risk*. Australian Journal of Agricultural and Resource Economics, 56(4), 597-620.  Wiley;

==original Abstract==

This paper provides an overview of the literature on production under the influence of risk. Various specifications of stochastic production function such as models with additive and multiplicative uncertainty, Just and Pope model, output-cubical, state-allocable and state-general models are discussed. Further, criteria determining optimal producer behaviour are derived for deterministic production technology and for various kinds of state-contingent technologies such as output-cubical, state-specific, state-allocable and state-general technologies. Finally, a brief discussion is presented about the drawbacks of each of these specifications of technology.

Note by yinung

這篇原是 DICE 的 working paper (see 本站另一篇 PO 文),現在刊出來了。

主要結論 (in abstract):

此文研究3種 PD game 實驗回合結束的方式 (告知結束回合、不告知結束回合、隨機結束),比較合作率之不同。 1. 三種結束方式不影響合作率 2. 隨機結束方式不會提高合作率 (相對於告知結束回合);不同繼續玩 (隨機結束) 之機率高低 (continuation probability) 亦不影響合作率 3. 結束方式會影響 over time 和 end-game 行為 4. 預期玩的回合愈長,合作率愈高

可引述

三種 termination rule:

  • finite horizon: Flood (1952) and Rapoport and Chammah (1965) … it is well known that stable cooperation does occur also in finitely repeated games
  • unknown horizon: Fouraker and Siegel 1963
  • random-stopping rule: to terminate the experiment (Roth and Murnighan1978; Axelrod 1980)

End-game effects: Morehous (1966) … defection rates increase towards the end of the game when the horizon of the game is known to be finite. … used a probabilistic termination rule so that “end-game effects were successfully avoided” (Axelrod 1984, p. 42). Murnighan and Roth (1983, p. 284) argue that “consideration of end-game play is less critical” with the random termination rule. Holt (1985, p. 320) makes the same point. 也有人在分析結果時,去掉最後幾回合 贊同應用隨機結束 With finitely many periods, the theory is bland; by contrast, the random termination rule “permits the nature of the equilibrium outcomes to be controlled” (Roth and Murnighan 1978, p. 191) Selten and Stoecker (1983) further noted that subjects learn to anticipate the endgame effect in that this effect is shifted to earlier rounds when a supergame with a finite horizon is repeated several times (see also Andreoni and Miller 1993) 隨機結束機率高者,使合作率較高 (與本文結果不一致),但重覆的實驗不能確定此一結果 Roth and Murnighan (1978) found that a random stopping rule with higher continuation probability does lead to more cooperation in the prisoner’s dilemma. However, in the modified setup analyzed in Murnighan and Roth (1983), this could not be confirmed. Dal Bo (2005) 發現隨機結束機率(在 supergame 玩 10 次後) 有重要影響

本文之實驗

至少玩 22 回合 (??? 不知何義,待了解… 因為結束回合數不一定一樣), 4 情境、每情境有15組人

  • Know
  • Unknow
  • RandomHigh (5/6 繼續機率)
  • RandomLow (1/6 繼續機率)

supergame 不重覆 (??)Subjects were rematched after the first supergame. 另外有 Shorter Horizon 額外較短實驗

  • Known5 (9組,2人一組)
  • Known10 (11組)
  • Random5+5 (11組;至少5回,5/6 繼續機率,平均期望值=10回,恰與 Known10 對照)

合作率 要小心合作率的定義!(各文獻不一定相同) 其 Table 2 中的合作率是 cooperte choices (不是 cooperate outcome, 所以22回合中才最多有 44 個 cooperate choices) 此文皆是利用 cooperate choice 來分析,Harvey Wichman (1970, J of Personality and Social Psychology) 也是用此定義 有的文獻合作率的數字是 cooperate outcome (兩人皆是 cooperate choice 才算合作) (引文)…In order to take the possible dependence of observations between paired players into account, we count each participating pair as one observation. Matrix of the game 從合作到背叛,邊際利得只有 1000-800 = 200, 反而對手損失 750 較多;若因此而雙方開始不合作,每期邊際損失 250,根本不值得背叛;但是一旦被背叛,當次邊際損失 700, 要3次背叛才得以報復。

================================
       背叛              合作 
背叛  (350, 350)      (1000, 50)
合作  (50, 1000)      (800, 800)
================================

文中所述之 5 個 results

  • Result 1. The termination rule does not significantly affect average cooperation.

2種隨機結束和告知回合、不告知 等 treatment 合作率無顯著不同 (Kruskal-Wallis test)

Known 和 RandomLow 合作率有下降趨勢 (significant time trend)

  • Result 3. A significant end-game effect occurs in all treatments except Unknown。
2種隨機結束和告知回合都有 End-game effect (在最後幾回合作率顯著逐漸下降的情況)。 折現率~= 4/13 時,{C,C} is a subgame perfect Nash equilibrium outcome of the infinitely repeated game if and only if the discount factor is larger than 4/13 ~ 0.31.
  • Result 4 The termination rule does not significantly affect average cooperation rates in treatments Known5, Known10, Random5+5.
  • Result 5 The length of the horizon of the game significantly increases cooperation rates.

Testing for differences in cooperation with all treatments jointly does not suggest significant results

Abstract

Cooperation in prisoner’s dilemma games can usually be sustained only if the game has an infinite horizon. We analyze to what extent the theoretically crucial distinction of finite versus infinite-horizon games is reflected in the outcomes of a prisoner’s dilemma experiment. We compare three different experimental termination rules in four treatments: a known finite end, an unknown end, and two variants with a random termination rule (with a high and with a low continuation probability, where cooperation can occur in a subgame-perfect equilibrium only with the high probability). We find that the termination rules do not significantly affect average cooperation rates. Specifically, employing a random termination rule does not cause significantly more cooperation compared to a known finite horizon, and the continuation probability does not significantly affect average cooperation rates either. However, the termination rules may influence cooperation over time and end-game behavior. Further, the (expected) length of the game significantly increases cooperation rates. The results suggest that subjects may need at least some learning opportunities (like repetitions of the supergame) before significant backward induction arguments in finitely repeated game have force.

Notes by yinung

此文提及 death of distance" (Cairncross, 2001) or “death of geography" 意思是

…the shrinking costs for transportation, especially transportation of messages’ pure in formation content.

必需有 face-to-face 溝通的原因是

… widely agreed that communication often must be face-to-face in order to be effective. But why?

1. nonverbal 和 verbal 同時發生,減少誤解(Storper and Venables, 2004; Winger, 2005, sections 4 – 6; and Hildrum, 2007, p. 469 with further references).

2. 比較有意義 (???待了解)

3. 發現想看到的,也發現原來沒想看到的隱含事務

4. buzzing (流言???)

5. face-to-face 溝通成本高,可視為建立長期關係之投資

6. 建立互信的必要條件

以上是理論,經濟實驗 (不含心理實驗)之證據為此文之回顧重點

匿名實驗結果有時不具參考性,此文同意此觀點 (至少用 email 溝通知道名字)

幾個與 face-to-face 相關因素

  1. 即時回應之效果 and 冷淨作用 Cooling effects: effect of spontaneity (decision time)  in Sec. 2
  2. trust 和合作受到 face-to-face 之影響 in Sec. 3
  3. 細節因素,如 smiling 和 eye contact  在 f2f 中之角色

冷靜效果

..experiment on the effect of a substantive cooling off period in an experiment was invented by Oechssler, Roider and Schmitz (2008).

在 ultimatum game 中,8:2 和 5:5 的分餅被提出,看對手是否接受。24小時後,接受的決定可以被修改。餅獎金大小分別有 2,5,8 euros. Cooling off period 並未導致拒絕率大幅降低 (from 42.6% to 39.4%) ,且不顯著。但將 reward 變大 (期望值相同,用 lottery 方式),則拒絕率顯著大幅下降 fom 27.7% to 20.5%.

增加決策時間之壓力也有同樣的效果 (提高拒絕率) increased time pressure might well increase the rejection rate by Sutter, Kocher and Strauß (2003). 決策時間減少 (100秒 mm> 10 秒),拒絕率增加從 40.3 to 78.2%。 Cappelletti, Güth and Ploner (2008) 也有類似的發現 (180秒 vs 30 秒)。情感區 (affective system) 和 (deliberative system) 在大腦中並不相同。

Implications:

在 UG 中,拒絕率上升,代表效率下降。出價者將會喜歡拒絕率降低 (因此可降低 offer); 反之,回應者將喜歡拒絕率上升。故,出價者將偏好 face-to-face 溝通。不過要注意的是 UG 是單向一次 negotiation, 一般的談判會有雙向回應

建立互信 & 合作

Valley, Moag and Bazerman (1998)

(註: 有時互信和合作很難區分 see

兩人買賣股票,出價B

只有 seller 知道 V; Seller 會接受 if B>V; seller 得到 (B-V);

Buyer 只知 V~uniform(0,100), 真實 V 要等 Buyer 買到以後才知道。真實價值 = 1.5V; buyer 得到 (1.5V-B);

Buyer 問 seller V=?, 但 seller 可以 lie; 不過 face-to-face 之下,seller 顯著地比較不可能 lie (face-to face 只有 1 of 14, 7% lie; 電話 55% lie; 不匿名witten 33% lie). 有些 face-to-face 的 buyer 並沒有問 seller V;

結果發現 face-to-face 導致比較多的 Pareto improving deals.

Pareto deals (雙方皆獲益)

face-to-face: 51.7% (out of n=21) 成交; 顯著大於 written comm. 但不顯著大於 telephone comm.

written comm.: 22.2% (未成交 52% 接近理論值)

telephone comm.: 38.1%

Non-Pareto deals (buy’s loss):

face-to-face: 23.8%

written comm.: 25.9%

telephone comm.: 47.6%

Frohlich and Oppenheimer (1998) PD game (應是 public good game)

5人一組玩多人 PD game 共 15 回合; 前 8 回合用 (a) 事先沒有 comm.; (b) email (c) face-to-face;

每人在每回合決定貢獻 0~10 給 group, 留下其餘。

S=5人貢獻之加總; 每人皆領回 0.4S

理論:每人皆貢獻 10, 則 S = 50,每人皆領回 0.4S = 20; 若每人皆貢獻 0, 則每人只得 10

實驗結果

各 treatment 之平均貢獻 (前 8回合

(a) 沒有 comm: 2.9

(b) email: 7.6

(c) face-to-face: 9.99

9回合以後(皆沒有 comm.)

Contributions in groups with previous face-to-face communication quickly collapse to the level of the e-mail-groups.

face-to-face 效果持續多久

一回合就夠了? (Brosig, Ockenfels and Weimann, 2003; Bochet et al., 2006)

6人一組玩28回合的 public good game;在第 10,15,20加入 face-to-face comm.;

每一回合貢獻 x of 13 tokens; 全部人之貢獻加總= S; 每人之 Payoffs = ???

face-to-face comm. 有助於 maximize group welfare 在後半段實驗; Email comm. 並沒有較高的合作;但實驗前一天 email comm. 的人 face-to-face 之後,卻有類似的效果。

Player 1 — [1.20, 1.20]

Player 1 是受試者,Player 2 是電腦但 show 照片 (treatment 是否微笑,取自相片資料庫),只要 Player 1 選擇 trust 策略,則電腦 (Player 2) 必定也用 trust 回應。結果發現, Player 1 之回應

沒有微笑: 55.0% 選擇 trust 策略
有微笑:     68.3%
(是否顯著待查)

eye contact

Bateson, Nettle and Roberts (2006)現地實驗中也發現,eye contact 會讓貢獻較多錢

在48位大學職員喝咖啡處貼眼睛海報 or 花海報各幾週,自願投幣奉獻 (honesty box) 金額

在貼眼睛海報的時候,自願投幣奉獻金額顯著較高

Abstract

The notion of face-to-face contacts has recently become very popular as a reason why firms still locate in proximity to others after the “death of distance.” Controlled laboratory experiments provide direct and reliable evidence on the importance of face-to-face contacts. It is the purpose of this article to survey and to organize new and developing string of literature with a special focus on its importance for regional economics. However, the article might also serve to alert more experimentalists to the importance of their work for current regional science, of which they seem not to be aware.

Team building and hidden costs of control

Riener, Gerhard and Wiederhold, Simon (2012) “Team building and hidden costs of control." DICE Discussion Paper 66, Düsseldorf Institute for Competition Economics (DICE).

==original abstract==

This paper investigates the interaction of intrinsic and extrinsic incentives. We propose a simple principal-agent model with control that incorporates the existence of social groups resulting from common experiences in the past. Our laboratory experiment shows that agents with previous common experiences with their principals (CE agents) perform better than agents without such experiences (NCE agents). However, as soon as actual control exceeds their expectation, CE agents decrease their performance substantially, which has no equivalent for NCE agents. This pronounced decrease in effort when control is perceived as excessive represents a novel channel through which hidden costs of control materialize. Our results have important implications for firms’ strategies to motivate employees.

Psychologists at the Gate: A Review of Daniel Kahneman’s Thinking, Fast and Slow*

==Notes by yinung==

這篇文章回顧 Daniel Kahneman 的書  “Thinking, Fast and Slow

… because the  book mentions few economic applications, I  will describe some of the economic research that has been substantially infuenced by  this work.

作者認為 Kahneman and Tversky 影響最大者在於 財務學 (或稱行為財務) … this work. My feeling is that the most profound infuence of Kahneman and Tversky’s work on economics has been in fnance, on what has now become the field of behavioral finance…

兩種常見反對將心理學引進經濟學的理由:

…two common objections to the introduction of psychology into economics,…

A. 經濟學較著重研究人類行為的一般觀點,而非特殊行為
… economists should focus on “first order things”rather than quirks (quirk 這個字原意是).

1. 反例1,人們花太多錢在保險,只為了很小的可能損失 (這可不是特殊現象),
individuals pay large multiples of actuarially fair value to buy insurance against small losses, as well as to reduce their deductibles (Sydnor 2010).

2. 反例2,廣告 (??還沒看懂)
the standard economic view that persuasion is conveyance of information seems to run into a rather basic problem that advertising is typically emotional, associative, and misleading— yet nonetheless effective (Bertrand et al. 2010; DellaVigna and Gentzkow 2010; Mullainathan, Schwartzstein, and Shleifer 2008).

3. 反例3,財務理論說,投資者應選 low-cast index fund, 但事實上大部份人卻是選 high-cost actively managed funds

B. 市場力量可消除心理因素對價格和分配之影響 (價格和效率)
… market forces eliminate the influence of psychological factors on prices and allocations.

1. 反例,Real-world arbitrage is costly and risky, and hence limited, … Dozens of empirical studies confirm that, even in markets with relatively inexpensive arbitrage, identical, or nearly identical, securities trade at different prices. With costlier arbitrage, pricing is even less efficient.

2. 市場參與者大多不理性,即是有專家之協助 (專家的動機通常值得懷疑,見(Chalmers and Reuter 2012; Gennaioli,
Shleifer, and Vishny 2012))
Market forces often work to strengthen, rather than to eliminate, the influence of psychology.
List 研究棒球卡交易,發現專家沒有 endowment effects, 支持了此一觀點。

兩個思考體系 (two systems)

System 1: 直覺、自動、非意識性、容易 (intuitive, automatic, unconscious, and effortles);快速反應,透過聯想、組合

System 2: 具意識性、緩慢、受控制 …但不容易 (conscious, slow, controlled, deliberate, effortful, statistical, suspicious, and lazy (costly to use));這是經濟學家認為的思考

Heuristics and Biases

Anchoring effects: 對未知的問題,容易受到前置性的影響 (擲俄羅斯輪盤,看到數字後,猜非洲國家佔聯合國之比例…, 看到輪盤數字小者猜小, 看到數字大者猜大)

… respondents receive all the information they need, but nonetheless do not use it correctly.

===一些結論…===

人類注意和聯想到的資訊,並非皆是在最佳決策中所需要的… 系統 1 的思考是自動反應,而非最佳化: 選擇性認知與記憶之決策行為(highly selective perception and memory … before we make decisions and choice)
… the fundamental feature of System 1 is that what our attention is drawn to, what we focus on, and what we recall is not always what is most necessary or needed for optimal decision making.

==original Abstract==

The publication of Daniel Kahneman’s book, Thinking, Fast and Slow, is a major intellectual event. The book summarizes, but also integrates, the research that Kahneman has done over the past forty years, beginning with his path-breaking work with the late Amos Tversky. The broad theme of this research is that human beings are intuitive thinkers and that human intuition is imperfect, with the result that judgments and choices often deviate substantially from the predictions of normative statistical and economic models. In this review, I discuss some broad ideas and themes of the book, describe some economic applications, and suggest future directions for research that the book points to, especially in decision theory.

An Experiment on the Causes of Bank Run Contagions

Date: 2012
By: Surajeet Chakravarty (Department of Economics, University of Exeter)

Todd Kaplan (Department of Economics, University of Exeter)
URL: http://d.repec.org/n?u=RePEc:exe:wpaper:1206&r=net
To understand the mechanisms behind bank run contagions, we conduct bank run experiments in a modified Diamond-Dybvig setup with two banks (Left and Right). The banks’ liquidity levels are either linked or independent. Left Bank depositors see their bank’s liquidity level before deciding. Right Bank depositors only see Left Bank withdrawals before deciding. We find that Left Bank depositors’ actions signicantly affect Right Bank depositors’ behavior, even when liquidities are independent. Furthermore, a panic may be a one-way street: an increase in Left Bank withdrawals can cause a panic run on the Right Bank, but a decrease cannot calm markets.
Keywords: bank runs, contagion, experiment, multiple equilibria.

Fee Versus Royalty Policy in Licensing Through Bargaining: An Application of the Nash Bargaining Solution

這是理論文章,證明 Royalty licensing 比 fixed fee licensing 來得好 for firms and social veiw.

裡頭有 licensing patents 的理論文獻

==引文==

理論證明 fixed 比 royalty 好 in Kamien and Tauman (1986)
…Despite the fact that a royalty is often observed, theoretical analyses including Kamien and Tauman (1986) showed that a
fixed fee was superior to a royalty for both the patent holder and consumers.

但 Kamien and Tauman (2002) and Wang (1998) 證明 royalty 比 fixed  好
…Kamien and Tauman (2002) extended the model of Wang (1998) to a Cournot oligopoly market, and showed that if the patent holder competed in the product market with a sufficiently large number of firms, then a royalty is superior to a fixed fee for
him/her.

談判方式: “take-it-or-leave-it“ (像 ultimatum game)
…These studies basically assumed a “take-it-or-leave-it” licensing manner; that is,  the patent holder first announces a level of a fixed fee (or a royalty), and then firms  decide whether or not to buy the patent. Analyses were done in terms of noncooperative game theory.

也有用合作賽局為理論架構來研究 for licensing the patent
…Tauman and Watanabe (2007) applied the Shapley value and showed that the patent holder’s profit in the Shapley value approximated his/her equilibrium profit in the noncooperative model of Kamien and Tauman (1986) as the number of firms became large. Watanabe and Muto (2008) characterized the upper bound and the lower bound of the patent holder’s profits in the bargaining set.

==original ABSTRACT==

In this paper, we consider a Cournot duopoly market in which the patent-holding firm negotiates with its rival firm about payments for licensing a cost-reducing innovation. Applying the Nash bargaining solution, we compare two licensing policies, a fixed fee and a royalty. Our results are as follows. Royalty licensing is better than fixed fee licensing for both firms if the innovation is not drastic. So, royalty licensing is always carried out. Moreover, though there exists a case in which consumers prefer fixed fee licensing, royalty licensing is always superior to fixed fee licensing from the social point of view.

集體決策和個人決策之差異:

從賽局理論的角度看, 集體決策較個人決策來得理性 (rational), 因其可避免認知錯誤與限制。

不過集體決策也因此不見得會提高社會福利 (集體決策比較 self-interest)

待研究問題:

the optimal size of the group ( A useful starting point here is Forsyth’s (2006) work)

==original Abstract==

In this paper, we describe what economists have learned about differences between group and individual decision-making. This literature is still young, and in this paper, we will mostly draw on experimental work (mainly in the laboratory) that has compared individual decision-making to group decision-making, and to individual decision-making in situations with salient group membership. The bottom line emerging from economic research on group decision-making is that groups are more likely to make choices that follow standard game-theoretic predictions, while individuals are more likely to be influenced by biases, cognitive limitations, and social considerations. In this sense, groups are generally less “behavioral" than individuals. An immediate implication of this result is that individual decisions in isolation cannot necessarily be assumed to be good predictors of the decisions made by groups. More broadly, the evidence casts doubts on traditional approaches that model economic behavior as if individuals were making decisions in isolation.

First-Mover Advantage in Two-Sided Competitions: An Experimental Comparison of Role-Assignment Rules

Bradley J. Ruffle and Oscar Volij, (2012) “First-Mover Advantage in Two-Sided Competitions: An Experimental Comparison of Role-Assignment Rules." Discussion Paper No. 12-08, Monaster Center for Economic Research, Ben-Gurion University of the Negev,  Israel.

Available at SSRN: http://ssrn.com/abstract=2128225 or http://dx.doi.org/10.2139/ssrn.2128225. [PDF]

Abstract: 

Kingston (1976) and Anderson (1977) show that the probability that a given contestant wins a best-of-2k 1 series of asymmetric, zero-sum, binary-outcome games is, for a large class of assignment rules, independent of which contestant is assigned the advantageous role in each component game. We design a laboratory experiment to test this hypothesis for four simple role-assignment rules. Despite the fact that play does not uniformly conform to the equilibrium, our results show that the four assignment rules are observationally equivalent at the series level: the fraction of series won by a given contestant and all other series outcomes do not differ across the four rules.
