More Trusting, Less Trust? An Investigation of Early E-Commerce in China -- by Hongbin Cai, Ginger Z. Jin, Chong Liu, Li-An Zhou

Trust is vital for market development, but how can trust be enhanced in a marketplace? A common view is that more trusting may help to build trust, especially in less developed economies. In this paper, we argue that more trusting may lead to less trust. We set up a rational expectation model in which a marketplace uses buyer protection to promote buyer trusting. Our results show that buyer protection may reduce trust in equilibrium and even hinder market expansion because it triggers differential entry between honest and strategic sellers and may induce more cheating from strategic sellers. Using a large transaction-level data set from the early years of Eachnet.com (an eBay equivalent in China), we find evidence that is consistent with the model predictions. Stronger buyer protection leads to less favorable evaluation of seller behavior and is associated with slower market expansion. These findings suggest that a trust-promoting policy aiming at buyer trusting may not be effective if it is not accompanied by additional incentives to improve seller trustworthiness.

Learning to Love Democracy: Electoral Accountability and the Success of Democracy

by Milan W. Svolik
Yiran Li

解释了为什么在一个新民主制中对于单个的政治家的失望不满会造成选民对于整个民主政治体制的失望。指出在新建的民主制中,民众对于将选举作为保证政治accountability的instrument的希望非常高,政治家要因此去建立reputation。这个新时期就被常被称为“一次致富的机会”。但是如果经过好多次失望,选民就会理性的认为“天下乌鸦一般黑”,即使是政治家们仍然在努力表现好。作者认为选民的这种期望造成了failure of accountability即悲观期待的陷阱,因此造成了民主制的breakdown.但是如果政治家通过好的表现赢得了巨大的reputation 这将成为那些低素质政客的屏障,而这种进步就会强化选民的民主belief。本文提供的就是这样一个宏观理论。

This article explains why dissatisfaction with the performance of individual politicians in new democracies often turns into disillusionment with democracy as a political system. The demands on elections as an instrument of political accountability are much greater in new than established democracies: politicians have yet to form reputations, a condition that facilitates the entry into politics of undesirable candidates who view this period as their “one-time opportunity to get rich.” After a repeatedly disappointing government performance, voters may rationally conclude that “all politicians are crooks” and stop discriminating among them, to which all politicians rationally respond by “acting like crooks,” even if most may be willing to perform well in office if given appropriate incentives. Such an expectation-driven failure of accountability, which I call the “trap of pessimistic expectations,” may precipitate the breakdown of democracy. Once politicians establish reputations for good performance, however, these act as barriers to the entry into politics of low-quality politicians. The resulting improvement in government performance reinforces voters’ belief that democracy can deliver accountability, a process that I associate with democratic consolidation. These arguments provide theoretical microfoundations for several prominent empirical associations between the economic performance of new democracies, public attitudes toward democracy, and democratic stability.

Why Vote with the Chief? Political Connections and Public Goods Provision in Zambia

by Kate Baldwin
Yiran Li

为什么地方赞助者(local patrons,地方精英)会影响选民的选举决定?既有文献对此的解释有两个方面,一个是说强制性的力量,即选举不透明就使得地方精英能够惩罚选民,所以选民会受到这种强制力的约束;第二个是说个人的责任强化了这种侍从主义(clientelism), 即党派个人的loyalty约束了选民的选举行为,本着互惠原则他们会倾向于选择patron喜欢的候选人。但是这两种解释都没有真正从考虑到选民选举的复杂评估过程。通过对于赞比亚政治的分析实验,通过实证作者得出三点结论:1)在许多发展中国家,选举出来的政治家需要与地方patron一起工作,并向当地提供公共物品,基于这个逻辑,选民在选举的时候就会考虑到patron与候选人的关系。2)patron与候选人的关系越好能够更有效的给地方提供公共物品。3)选民就会倾向于选择与他们的patron关系更好的候选人,如果他们感受到了他们一起工作能够给地方带来的好处。本文中chief代表地方精英patron,指的是族长,村长这种。用chief跟政治家认识的年份来measure他们之间的关系。

Why are voters influenced by the views of local patrons when casting their ballots? The existing literature suggests that coercion and personal obligations underpin this form of clientelism, causing voters to support candidates for reasons tangential to political performance. However, voters who support candidates preferred by local patrons may be making sophisticated political inferences. In many developing countries, elected politicians need to work with local patrons to deliver resources to voters, giving voters good reason to consider their patron's opinions of candidates. This argument is tested using data from an original survey of traditional chiefs and an experiment involving voters in Zambia. Chiefs and politicians with stronger relationships collaborate more effectively to provide local public goods. Furthermore, voters are particularly likely to vote with their chief if they perceive the importance of chiefs and politicians working jointly for local development.

文/石章强 叶建伟
    当2012年的服装业寒冬来袭,当曾经的服装连锁业老大GAP被挤下王座,以ZARA、H&M等为首的靠建设极速产业链而在市场中屹立不倒的企业却默默的经营着自己门庭若市的店铺。ZARA到底拥有怎样的绝招?它究竟在哪些环节领先行业?它又是如何打造属于自己的快时尚极速产业链的呢? 
有人说2012年是中国服装业的寒冬,也有人说现在服装业的库存,中国人白穿3年都穿不完,相信大多数人听到这个说法会倒抽一口凉气,随即反应过来的是“那为什么现在衣服还这么贵?”这是因为2012年仅22家A股服装类上市公司第三季度的存货总量就达到了惊人的382亿元。在这个数字爆出之前,上半年42家服装企业总积压库存483亿元的状况已经令人咋舌。库存就意味着无止尽的成本投入,这种库存量已经成了不可能完成的任务,正在把中国的服装企业拉进万劫不复的深渊。
在这种大现象的背后,越来越多的目光转向了ZARA这样靠建设极速产业链而在市场中逆势上扬的企业,越来越多的... ... 查看更多

The Ethnicity-Policy Preference Link in Sub-Saharan Africa

by Lieberman, E. S., McClendon, G. H.
Yiran Li

既往研究习惯于将ethnic diversity and Low public goods provision联系起来,但是基本上都认为民族多样性与对于公共物品的偏好没有系统的关系,即偏好不会随着不同民族而系统改变。本文反驳这个观点,用撒哈拉非洲的数据,证明了其实偏好确实随着民族的不同而改变,即这种变化不仅仅是个人社会经济不同的表达或者是民族之间文化不同的表达,作者认为人民可以运用ethnicity as a group heuristic(启发)去评估公共政策——即对于公共物品的偏好的disagreement最显著的存在于政治上联系更为紧密的group之间和种族平均财富差距比较大的group之间。

Scholars have begun to investigate the mechanisms that link ethnic diversity to low levels of public goods provision but have paid only minimal attention to the role of preferences for public policies. Some argue that ethnic groups hold culturally distinctive preferences for goods and policies, and that such differences impede effective policy making, but these studies provide little evidence to support this claim. Others argue that preferences do not vary systematically across ethnic groups, but again the evidence is limited. In this article, we engage in a systematic exploration of the link between ethnic identity and preferences for public policies through a series of individual and aggregated analyses of Afrobarometer survey data from 18 sub-Saharan African countries. We find that in most countries, preferences do vary based on ethnic group membership. This variation is not merely an expression of individual-level socioeconomic differences or of group-level cultural differences. Instead, we suggest that citizens use ethnicity as a group heuristic for evaluating public policies in a few predictable ways: We find more persistent disagreement about public policies between politically relevant ethnic groups and where group disparities in wealth are high.

Social Identification and Ethnic Conflict

Yiran Li

什么时候民族分裂(ethnic cleavage)会增加冲突的危险?什么条件下一个比较strong的identity会产生并且能够降低冲突的危险?冲突能够塑造什么样pattern的social identification?作者建模实证。模型表现了在善意与邪恶两个循环内冲突与认知类型是如何相互强化的。表明了ethnic identification是如何扩大political institution的重要性的以及国家地位和国家与民族之间的区别对于各个民族group的影响。强调了民族group中如果有小部分的强有力的极端者就有可能破坏和平的均衡,导致整个人口分化。基本上是回答“how”的问题,只是解释了内部机制。政策上面的建议就是:比如要提高国家的地位,在national building的时候就要强调国家的地位,进行教育宣传等。

The Feudal Revolution and Europe's Rise: Political Divergence of the Christian West and the Muslim World before 1500 CE

Yiran Li

欧洲世界在1100年以后比伊斯兰世界更加稳定,领导人的寿命时间更长,而主权的约束随着任期的增长而变强,且欧洲的执行机构组成的模式更加客观,少personal的关系。而欧洲世界的封建体制是为欧洲统治者的军事统治服务的.穆斯林世界的统治者因为有较强的finance capacity etc. 能够从非穆斯林的土地中进口奴隶作为士兵,也因此他们就不同于欧洲,欧洲统治者则要与Local elite bargain才能加强军事方面的统治,而这些阻碍了ruler and local elites之间的良性发展。所以作者认为穆斯林社会不似欧洲那样依靠local elites也许是光荣革命没有发生在埃及的原因。

Fight the Youth: Youth Bulges and State Repression

by Ragnhild Nordås, Christian Davenport
Yiran Li

逻辑就是,年轻人容易比较激进,就发现在face youth bulges(年轻人激增)的国家中,政府会比较repressive(镇压),meaning是更加关乎state strategy.国家政策未来走向,等等。

It is generally acknowledged that large youth cohorts or “youth bulges” make countries more susceptible to antistate political violence. Thus, we assume that governments are forewarned about the political demographic threat that a youth bulge represents to the status quo and will attempt to preempt behavioral challenges by engaging in repression. A statistical analysis of the relationship between youth bulges and state repression from 1976 to 2000 confirms our expectation. Controlling for factors known to be associated with coercive state action, we find that governments facing a youth bulge are more repressive than other states. This relationship holds when controlling for, and running interactions with, levels of actual protest behavior. Youth bulges and other elements that may matter for preemptive state strategies should therefore be included in future empirical models of state repression.

Religious Participation and Economic Conservatism

by Ben Gaskins, Matt Golder, David A. Siegel
Yiran Li

本文解释的问题是:为什么有些人会参与更多的宗教活动?宗教活动是如何影响这些人的经济态度的。作者apply了一个formal model能够区分个人的俗世与宗教的sources。模型内生了个人的宗教参与与其对于经济政策的偏好,用了70个国家的data给出实证,发现:宗教参与随着societal development, individual’s ability to produce secular goods, and state regulations on religion而下降,但是宗教随着inequality的增加而增加。宗教参与在穷人中使得人们的经济态度更加保守(increase the economic conservatism among the poor),但是在富人中却不会降低。

文章涉及两方面的文献:宗教参与,宗教与经济态度的关系。宗教参与:关于宗教的研究的核心理论就是世俗化理论(secularization theory), 着重研究对于宗教的需求,即认为随着社会的发展宗教和国家这种形式都将消失。本文则是只在宗教参与的范围内讨论demand-side explanations of religion。 但是对世俗化理论一直存在批判,从理论到实证批判该理论,这派人更注重从supply-side 分析宗教的需求,宗教的市场等等。作者认为这两派都不能全然弃之,既有研究只是注重研究富有的国家而缺乏足够的variation in societal development. 因而作者克服了既往研究的问题,用world value survey的data 来测量societal development。宗教参与与经济态度:既有文献中对宗教参与对人经济态度的影响也有研究。缺点是没有考虑到财富再分配的政治经济逻辑。

Why do some individuals engage in more religious activity than others? And how does this religious activity influence their economic attitudes? We present a formal model in which individuals derive utility from both secular and religious sources. Our model, which incorporates both demand-side and supply-side explanations of religion, is unusual in that it endogenizes both an individual's religious participation and her preferences over economic policy. Using data on over 70 countries from the pooled World Values Survey, we find that religious participation declines with societal development, an individual's ability to produce secular goods, and state regulations on religion, but that it increases with inequality. We also find that religious participation increases economic conservatism among the poor but decreases it among the rich. Our analysis has important insights for the debate about secularization theory and challenges conventional wisdom regarding the relationship between religious participation and economic conservatism.

Economic Performance and Democratic Support in Asia's Emergent Democracies

by Yap, O. F.
Yiran Li

经济表现在意外的民主制(emergent democracies)下是如何影响对于民主制的支持呢?现有的政府赞同(government approval) 并不能直接评估这点。现有的文献主要是用分开的两个标准评估这个问题。 在emergent democracies中的市民,通过政治信任(political trust)他们能够区分两个概念,即government approval and democratic support. 本文通过对亚洲国家,台湾,泰国,南韩和菲律宾的研究直接评估了上面的问题。有两个结果: 1)经济表现能够解释这些国家的government approval. 2)以往研究认为政治信任能够在emergent democracy中增加他们的democratic support. 且对于民主制的支持不因为好的经济表现而妥协。本文的研究就进一步理论化了前人的发现,认为政治信任(作为一种缓冲器,以至于市民支持民主制)在民主化体系中不是由经济表现决定的。反而政治信任能够让官员accountable for failure to steer the economy. 且政治信任能够让市民们分清楚两个概念,用经济表现去衡量政府的不作为 vs. 用经济表现衡量民主化的提起。所以说作者认为在emergent democracies中,economic accountability 不会阻碍其民主化集成。 所以说在这种体系下,市民们既能够让官员变得负责人但是同时他们也会保留对于民主制度的支持。

How does economic performance affect support for democracy in emergent democracies? Government approval studies do not directly evaluate this. Recent literature suggests using separate assessments: Citizens in emergent democracies—through political trust—distinguish between government approval and democratic support. This article directly assesses the question for Asia’s democratizing nations of Taiwan, Thailand, South Korea, and the Philippines. Two results are relevant: First, economic performance explains government approval over time and across these democratizing nations. This result accords with findings from other regions to lend to the accumulation of knowledge from extending study to Asia. Second, economic performance does not explain democratic support; instead, political trust is statistically related to democratic support. Specifically, although political trust and economic performance both explain government approval, political trust outweighs economic conditions in explaining democratic support. These results show that by building political trust in the democratizing system, citizens may hold officials accountable while remaining committed to democratic development. Theoretically, then, this article synthesizes diverse findings in the literature to enrich theory building.

Elections and Democratization in Authoritarian Regimes

by Daniela Donno
Yiran Li

作者把威权政府分为两类,一种是competitive authoritarian regimes (CAR,反对党有一定作用,能够提出challenge并能获得一定的议席) ,另一种是hegemonic authoritarian regimes (HAR,一个党或者联盟占据议会70-75%以上的席位). 解答的问题是:为什么在electoral authoritarian regime中,election有时候能够作为支持威权政府的工具,但是有时又会削弱它? 作者argue relatively weak incumbents导致CAR的选举更加民主化,但是只在国内国际的actors都选择更加活跃的Pressure the regime的时候。作者指出要有两种压力:一个是在选举同盟中的反对派的压力,一种是国际压力。作者提出三个假设1)反对同盟对于民主的影响在CAR比在HAR更高;2)来自国际的压力对于CAR要高于HAR,3)在CAR的选举要更容易导致民主化因为CAR对于国际国内的压力更加的脆弱。作者用了electoral authoritarian 1990-2007所有的国家的data论证了这三个假设。同时作者也检验了其他的可能解释:国家类型的不同被解释为alternation in power, better electoral conduct or ongoing processes of liberalization 。被发现都不能解释本文的问题。

When do elections in authoritarian regimes lead to democracy? Building from the distinction between competitive and hegemonic authoritarian regimes, I argue that presence of relatively weaker incumbents renders competitive authoritarian elections more prone to democratization, but only when domestic and international actors choose to actively pressure the regime. The effects of two forms of pressure—opposition electoral coalitions and international conditionality—are theorized. Propositions are tested using a comprehensive dataset of elections in authoritarian regimes from 1990 to 2007. Results support two core claims: that the effect of electoral pressure is conditional on the type of authoritarianism and that this greater vulnerability to pressure is the reason why competitive authoritarian elections are more likely to lead to democracy. In contrast, several alternative explanations—that differences across regime type are explained by alternation in power, better electoral conduct, or ongoing processes of liberalization—are not supported by the evidence.

The Effects of Structures and Power on State Bargaining Strategies

by Heather Elko McKibben
Yiran Li

在国际政治中,经典的论调是国家自身的实力等决定了外交谈判中的输赢。但是作者观察到在实力很牛的大国,譬如美国这样的国家,为什么在和其他弱小过家家谈判中仍然会有concession呢?这篇文章就是解答这个问题的。作者认为决定这个问题的因素是institutional bargaining structure. 因为一个理性的国家,不管他的自身实力和socialization effects到达什么程度, 在一个给定的谈判中都是会尽量获取自身的好处的。 于是当他们意识到谈判的框架或者倾向是不利于他们自己国家的时候,他们就会希望能达到一个agreement. 基于此,作者提出了5个假设并通过欧盟外交的data论证了这五个假设。 1)如果对于一个议题国家间的利益非常不一致,那么concession就比较容易达成。2)在谈判中,有更好的外部选择的国家会运用concession-extracting技巧(让步提取,跟让步相对),而那些外部选择对自身比较costly的国家就比较容易提出并接受concession.3) 一国的谈判者受到的约束越多(可能是来自本国的,他们自身的权利啦,由于principal-agent批准过程的限制,),那么这样的国家更容易运用concession-extracting tactics. 4) 在一个consensus decision rule的谈判框架下,国家间更容易采取concession-extracting,而在一个majority decision rule的谈判框架下则不然;5)在比较公众,透明的谈判中,国家间less likely to offer concessions.

When and why will states adopt more (or less) cooperative bargaining strategies? Standard answers to this question focus on the role of state power. Other scholars highlight socialization effects. I argue that in most international negotiations, the institutional bargaining structure will mitigate the effects of power and socialization, and drive state bargaining behavior. Factors highlighted by formal models of international bargaining should therefore best explain the variation in the strategies states adopt. I introduce empirical measures of these abstract concepts, and test their effects against those of power and socialization using an original dataset of state bargaining strategies in the European Union (EU). The results show that structural factors best explain variation in the EU states’ bargaining strategies. I conclude by highlighting the conditions under which these effects should explain state bargaining behavior in other international negotiations, and discuss the implications of this argument for the study of international bargaining.

In Defense of Genopolitics

follow APSR 2008年的一篇文章,那是关于基因与政治学交融的第第一篇文章,也是在APSR领域第一次“twin study",This study replicates the gene-environment interaction of the 5HTT gene variant with church attendance, but not the association with MAOA. We then
focus on the general argument of the critique, showing that many of its characterizations of the literature in genetics and in political science are misleading or incorrect. we showed that patterns of voter turnout and political
participation were significantly more similar between
identical twins than they were between fraternal(异卵双生) twins.
