Are courts effective monitors of corporate decisions? In a controversial landmark case, the Delaware Supreme Court held directors personally liable for breaching their fiduciary duties, signaling a sharp increase in Delaware’s scrutiny over corporate decisions. In our event study, low-growth Delaware firms outperformed matched non-Delaware firms by 1% in the three day event window. In contrast, high-growth Delaware firms under-performed by 1%. Contrary to previous literature, we conclude that court decisions can have large, significant and heterogeneous effects on firm value, and that rules insulating directors from court scrutiny benefit the fastest growing sectors of the economy.
法院是公司决策的有效监督者吗?在一起具有里程碑意义的争议案件中,特拉华州最高法院裁定董事个人应对违反受托责任负责,这标志着特拉华州对公司决策的审查力度大幅加强。在我们的事件研究中,在三天的事件窗口中,低增长的特拉华州公司的表现比匹配的非特拉华州公司高出1%。相比之下,特拉华州的高增长公司表现落后1%。与之前的文献相反,我们得出的结论是,法院判决可以对公司价值产生巨大、显著和异质性的影响,并且使董事免受法院审查的规则有利于经济增长最快的部门。

Inflation Targeting Monetary and Fiscal Policies in a Two-Country Stock-Flow Consistent Model 两国股票流动一致性模型下的通货膨胀目标制货币与财政政策

This paper develops a simple two-country stock–flow-consistent model based on that of Godley and Lavoie. In order to motivate the use of stabilisation policies, persistent inflationary pressure and endogenous economic cycles are introduced into the model. Three scenarios are then simulated: a step decrease in real exports from country B, increased wage pressure in country B and an income tax cut in country A. In all cases, monetary and fiscal policies in isolation enjoy little success, but a combined monetary and fiscal approach to stabilisation proves highly effective. Moreover, the model suggests that the pursuit of autonomous inflation targeting in each country introduces excessive exchange rate volatility relative to an alternative rule in which one central bank takes a leading role in interest rate setting.
本文在Godley和Lavoie的基础上,建立了一个简单的两国股票流量一致性模型。为了激励稳定政策的使用,持续的通胀压力和内生经济周期被引入模型。然后模拟了三种情况:B国实际出口逐步减少,B国工资压力增加,a国所得税削减。在所有情况下,单独的货币和财政政策收效甚微,但货币和财政相结合的稳定办法证明是非常有效的。此外,该模型表明,相对于由一家央行主导利率设定的另一种规则,各国追求自主通胀目标制会带来过度的汇率波动。

Voting on Punishment Systems within a Heterogeneous Group 在异质群体中对惩罚制度的投票
Pub Date : 2011-10-01 DOI: 10.2139/ssrn.1368662
C. Noussair, Fangfang Tan
We consider a voluntary contributions game, in which players may punish others after contributions are made and observed. The productivity of contributions, as captured in the marginal-per-capita return, differs among individuals, so that there are two types: high and low productivity. Every two or eight periods, depending on the treatment, individuals vote on a punishment regime, in which certain individuals are permitted, but not required, to have punishment directed toward them. The punishment system can condition on type and contribution history. The results indicate that the most effective regime, in terms of contributions and earnings, is one that allows punishment of low contributors only, regardless of productivity. Nevertheless, only a minority of sessions converge to this system, indicating a tendency for the voting process to lead to suboptimal institutional choice.
我们考虑一个自愿捐款的游戏,在这个游戏中,玩家可以在捐款和观察后惩罚其他人。正如边际人均回报所反映的那样,贡献的生产率在个人之间是不同的,因此有两种类型:高生产率和低生产率。每隔两个或八个时期,根据对待的不同,个人投票决定一种惩罚制度,在这种制度中,某些人被允许,但不是必须,对他们进行惩罚。处罚制度可以根据类型和贡献历史而定。研究结果表明,就贡献和收入而言,最有效的制度是只允许惩罚贡献少的人,而不管生产率如何。然而,只有少数会议采用这一制度,这表明投票过程有导致次优制度选择的趋势。

When Does Knowledge Become Intent?: Perceiving the Minds of Wrongdoers 知识何时变成意图?:感知犯错者的思想
Pub Date : 2011-07-12 DOI: 10.2139/ssrn.1884518
Pam Mueller, L. Solan, J. Darley
In a series of experimental studies, we asked people to assign appropriate civil and/or criminal liability to individuals who cause harm with various states of mind and kinds of knowledge. The studies are principally aimed at two puzzles: First, do people actually separate the various states of mind conceptually? How much knowledge, and what kind of knowledge, regarding something may go wrong (understanding risk) is sufficient to count as knowing that something will go wrong (having knowledge)? Second, to the extent that people distinguish among the states of mind that help to define normative behavior, how much do those distinctions contribute to people’s judgments of liability, both criminal and civil? Our studies show that people are able to make explicit distinctions about the states of mind of others that more or less correspond to legally-relevant categories. Yet, when asked to assign consequences, their moral judgments play a larger role than do their cognitive categorizations.
在一系列的实验研究中,我们要求人们对以不同的精神状态和知识种类造成伤害的个人分配适当的民事和/或刑事责任。这些研究主要是为了解决两个难题:第一,人们是否真的从概念上区分了不同的心理状态?关于某件事可能出错(了解风险),有多少知识和什么样的知识足以算作知道某件事会出错(拥有知识)?第二,在某种程度上,人们区分有助于定义规范行为的心理状态,这些区分对人们判断刑事和民事责任有多大影响?我们的研究表明,人们能够对他人的心理状态做出明确的区分,这些状态或多或少与法律相关的类别相对应。然而,当被要求分配结果时,他们的道德判断比他们的认知分类发挥更大的作用。

The Price Effects of Event Risk Protection: The Results from a Natural Experiment 事件风险保护的价格效应:一个自然实验的结果
Pub Date : 2010-07-16 DOI: 10.2139/ssrn.1641304
Karl S. Okamoto, David J. Pedersen, N. Pedersen
Prior studies have generally agreed that bond prices reflect both the event risk faced by the holders of a particular issuer’s debt securities and the degree of protection from event risk contained within the terms of the bond. Therefore, it has been found that bonds without event risk protection command a premium over comparable bonds with “change in control puts” or similar protective covenants. Although prior studies have reached this common conclusion, each has struggled with a common problem. The decision to include protective covenants is endogenous. Bonds facing the highest event risk are likely to be those for which event risk protection is most highly valued. Therefore a determination of the pricing effect of event risk protection must somehow control for the differing degree of event risk faced by the different bonds included in any given study’s sample. While various proxies for the likelihood of an event, a leveraged buyout or recapitalization, have been developed, they are by their nature imprecise. A recent event, a series of court decisions regarding the proposed leveraged buyout of Bell Canada, the largest LBO transaction announced in history, provides a natural experiment for evaluating the pricing effect of event risk protection in corporate bonds that avoids the endogeniety problem. We report the results of that experiment in this paper.
先前的研究普遍认为,债券价格既反映了特定发行人债务证券持有人所面临的事件风险,也反映了债券条款中所包含的对事件风险的保护程度。因此,研究发现,没有事件风险保护的债券比具有“控制权变更看跌期权”或类似保护性契约的可比债券溢价。尽管之前的研究已经得出了这个共同的结论,但每个研究都遇到了一个共同的问题。纳入保护性契约的决定是内生的。面临最高事件风险的债券可能是那些最重视事件风险保护的债券。因此,确定事件风险保护的定价效应必须在某种程度上控制任何给定研究样本中包含的不同债券所面临的不同程度的事件风险。虽然人们已经开发出各种各样的指标来衡量杠杆收购或资本重组等事件发生的可能性,但它们本质上是不精确的。最近发生的一件事是,法院就加拿大贝尔公司(Bell Canada)拟议的杠杆收购(史上宣布的最大杠杆收购交易)做出了一系列裁决,这为评估避免内生问题的公司债券事件风险保护的定价效果提供了一个自然的实验。我们在本文中报告了该实验的结果。

Measuring Trust: Experiments and Surveys in Contrast and Combination 信任测量:对比与结合的实验与调查
Pub Date : 2009-03-01 DOI: 10.2139/ssrn.1367375

Trust is a concept that has attracted - significant attention in economic theory and research within the last two decades: it has been applied in a number of contexts and has been investigated both as an explanatory and as a dependent variable. In this paper, we explore the questions of what exactly is measured by the diverse survey-derived scales and experiments claiming to measure trust, and how these different measures are related. Using nationally representative data, we test a commonly used experimental measure of trust for robustness to a number of interferences, finding it to be mostly unsusceptible to stake size, the extent of strategy space, the use of the strategy method, and the characteristics of the experimenters. Inspired by criticism of the widespread trust question used in many surveys, we created a new, improved survey trust scale consisting of three short statements. We show that the dimension of this scale is distinct from trust in institutions and trust in known others. Our new scale is a valid and reliable measure of trust in strangers. The scale is valid in the sense that it correlates with trusting behaviour in the experiment. Furthermore, we demonstrate that the test-retest reliability of six weeks is high. The experimental measure of trust is, on the other hand, not significantly correlated with trust in institutions nor with trust in known others. We therefore conclude that the experimental measure of trust refers not to trust in a general sense, but specifically to trust in strangers.
在过去的二十年里,信任是一个在经济理论和研究中引起了极大关注的概念:它已被应用于许多背景下,并作为解释变量和因变量进行了研究。在本文中,我们探讨了不同的调查衍生的尺度和实验声称测量信任到底是什么,以及这些不同的测量是如何相关的问题。使用具有全国代表性的数据,我们测试了一种常用的信任实验测量方法对许多干扰的稳健性,发现它基本上不受股权规模、策略空间的程度、策略方法的使用和实验者的特征的影响。受到对许多调查中广泛使用的信任问题的批评的启发,我们创建了一个新的,改进的调查信任量表,由三个简短的陈述组成。我们表明,这个尺度的维度不同于对机构的信任和对已知他人的信任。我们的新量表是对陌生人信任的有效和可靠的衡量。量表是有效的,因为它与实验中的信任行为相关。此外,我们还证明了六周的重测信度很高。另一方面,信任的实验测量与对机构的信任或对已知他人的信任没有显著相关。因此,我们得出结论,信任的实验测量不是指一般意义上的信任,而是指对陌生人的信任。

Desperate Vs. Deadbeat: Can We Quantify the Effect of the Bankruptcy Abuse Prevention and Consumer Protection Act of 2005? 绝望vs游手好闲:我们能量化2005年破产滥用预防和消费者保护法的效果吗?
Pub Date : 2008-10-23 DOI: 10.2139/ssrn.1298632

For decades, personal bankruptcies increased in the U.S., either reflecting growing economic distress of families or a declining stigma associated with filing for bankruptcy. In a nod to the latter argument, the U.S. Congress passed the Bankruptcy Abuse Prevention and Consumer Prevention Act of 2005 (BAPCPA), after bankruptcies had grown to record high rates. The assumption was that with the new law many if not most bankruptcies would eventually disappear since they supposedly were the result of a “bankruptcy of convenience”. The U.S. bankruptcy rate fell indeed sharply after the law went into effect, but increased quickly again afterwards. By the end of 2007, the U.S. bankruptcy rate exceeded all levels recorded during the 1980s, and approached the levels prevalent during the early 1990s. But it remains unclear how much of these changes resulted from BAPCPA and what was attributable to other factors. In this Working Paper, the authors establish a benchmark level of the U.S. bankruptcy rates after 2005 that likely would have been observed if the law had not changed. They then compare the actual U.S. bankruptcy rate to the benchmark for 2007 to provide a sense of the effectiveness of BAPCPA.
几十年来,美国的个人破产数量一直在增加,这要么反映了家庭经济困境的加剧,要么反映了申请破产的耻辱感在下降。鉴于后一种观点,美国国会通过了《2005年破产滥用预防和消费者保护法案》(BAPCPA),当时破产率已升至历史新高。人们的假设是,有了新法律,许多(如果不是大多数)破产将最终消失,因为它们被认为是“便利破产”的结果。该法生效后,美国的破产率确实急剧下降,但此后又迅速上升。到2007年底,美国的破产率超过了20世纪80年代的所有记录水平,接近20世纪90年代初的普遍水平。但目前尚不清楚这些变化有多少是由BAPCPA引起的,以及其他因素造成的。在这份工作报告中,作者建立了一个2005年后美国破产率的基准水平,如果法律没有改变,这个水平很可能会被观察到。然后,他们将美国的实际破产率与2007年的基准进行比较,以了解BAPCPA的有效性。

Male and Female Competitive Behavior: Experimental Evidence 男性和女性竞争行为:实验证据
Pub Date : 2005-11-01 DOI: 10.2139/ssrn.851227
Nabanita Datta Gupta, Anders U. Poulsen, M. Villeval
Male and female choices differ in many economic situations, e.g., on the labor market. This paper considers whether such differences are driven by different attitudes towards competition. In our experiment subjects choose between a tournament and a piece-rate pay scheme before performing a real task. Men choose the tournament significantly more often than women. Women are mainly influenced by their degree of risk aversion, but men are not. Men compete more against men than against women, but compete against women who are thought to compete. The behavior of men seems primarily to be influenced by social norms whose nature and origin we discuss.
男性和女性的选择在许多经济情况下是不同的,例如在劳动力市场上。本文考虑这种差异是否由不同的竞争态度所驱动。在我们的实验中,受试者在执行真正的任务之前,在锦标赛和计件工资计划之间做出选择。男性选择比赛的频率明显高于女性。女性主要受其风险厌恶程度的影响,而男性则不然。男人与男人的竞争多于与女人的竞争,但与被认为是竞争的女人竞争。男人的行为似乎主要受到社会规范的影响,我们将讨论社会规范的性质和起源。

Unintended Consequences of Property Tax Relief: New York’s STAR Program 财产税减免的意外后果:纽约的STAR计划
Pub Date : 2005-10-01 DOI: 10.2139/ssrn.1814022

New York’s School Tax Relief Program, STAR, provides state-funded property tax relief for homeowners. Like a matching grant, STAR changes the price of public services, thereby altering the incentives of voters and school officials and leading to unintended consequences. Using data for New York State school districts before and after STAR was implemented, we find that STAR resulted in small increases in student performance along with significant decreases in the efficiency with which this performance is delivered and significant increases in school spending and property tax rates. These tax-rate increases magnify existing inequities in New York State’s education finance system.
纽约的学校税收减免计划(STAR)为房主提供国家资助的财产税减免。就像配套补助金一样,STAR改变了公共服务的价格,从而改变了选民和学校官员的动机,并导致了意想不到的后果。使用实施STAR前后纽约州学区的数据,我们发现STAR导致学生成绩的小幅提高,同时表现的效率显著降低,学校支出和财产税税率显著增加。这些税率的增加加剧了纽约州教育财政体系现有的不平等。

These tax-rate increases magnify existing inequities in New York State’s education finance system.","PeriodicalId":126614,"journal":{"name":"LSN: Experimental Studies (Topic)","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121498052","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Several analytical models explain post-earnings-announcement drift, momentum and mean-reversion by making assumptions about investor behavior. They posit that investors react more strongly as a series of similar earnings surprises continues. Related literature suggests that behavior should vary systematically with investor sophistication. This paper tests these claims by analyzing whether traders on the NYSE exhibit increasing reactions to a series of similar earnings surprises, and whether their behavior varies with trade size, a proxy for sophistication. Results show that smaller traders exhibit an increasing reaction, with significant increases between the first, second, and third surprise. The pattern is weaker for larger trade-size groups, disappearing for the largest. Controls for prior returns show that small traders generally act as contrarians and large traders as momentum traders, strengthening the results. Future drift is weaker for each subsequent surprise in a series, suggesting that increasing reactions are not attempts to capitalize on increasing returns.
一些分析模型通过对投资者行为的假设来解释收益公布后的漂移、动量和均值回归。他们认为,随着一系列类似的意外收益继续出现,投资者的反应会更加强烈。相关文献表明,行为应该随着投资者的成熟程度而系统性地变化。本文通过分析纽约证券交易所的交易员是否对一系列类似的盈利意外表现出越来越强的反应,以及他们的行为是否随着交易规模(成熟度的代表)而变化,来检验这些说法。结果显示,较小的交易者表现出越来越强烈的反应,在第一次,第二次和第三次惊喜之间显著增加。对于规模较大的集团,这种模式较弱,对于规模最大的集团则消失。对先前收益的控制表明,小交易者通常作为反向交易者,大交易者作为动量交易者,从而加强了结果。在接下来的一系列意外事件中,未来的波动会减弱,这表明,不断增加的反应并不是试图利用不断增长的回报。
