Technological advances and the development of social media have made petitions, public protests, and other form of spontaneous activism increasingly common tools for individuals to influence decision makers. To study these phenomena, in this article I present a theory of petitions and public protests that explores their limits as mechanisms to aggregate information. The key assumption is that valuable information is dispersed among citizens. Through petitions and protests, citizens can signal their private information to the policy maker, who can then choose to use it or not. I first show that if citizens’ individual signals are not sufficiently precise, information aggregation is impossible, no matter how large is the population of informed citizens, even if the conflict with the policy maker is small. I then characterize the conditions on conflict and the signal structure that guarantee information aggregation. When these conditions are satisfied, I show that full information aggregation is possible as the population grows to infinity. When they are not satisfied, I show that information aggregation may still be possible if social media are available.
技术进步和社交媒体的发展使请愿、公众抗议和其他形式的自发行动主义越来越成为个人影响决策者的常用工具。为了研究这些现象,在本文中,我提出了请愿和公众抗议的理论,探讨了它们作为信息聚合机制的局限性。关键的假设是,有价值的信息分散在公民中。通过请愿和抗议,公民可以向政策制定者发送他们的私人信息,然后政策制定者可以选择使用或不使用这些信息。我首先表明,如果公民的个人信号不够精确,信息聚合是不可能的,无论知情公民的数量有多大,即使与决策者的冲突很小。然后,我描述了冲突的条件和保证信息聚合的信号结构。当满足这些条件时,我证明了当种群增长到无穷大时,完全的信息聚合是可能的。当他们不满意时,我表明,如果社交媒体可用,信息聚合仍然是可能的。

I derive a lower bound on the equity premium in terms of a volatility index, SVIX, that can be calculated from index option prices. The bound implies that the equity premium is extremely volatile and that it rose above 20% at the height of the crisis in 2008. The time-series average of the lower bound is about 5%, suggesting that the bound may be approximately tight. I run predictive regressions and find that this hypothesis is not rejected by the data, so I use the SVIX index as a proxy for the equity premium and argue that the high equity premia available at times of stress largely reflect high expected returns over the very short run. I also provide a measure of the probability of a market crash, and introduce simple variance swaps, tradable contracts based on SVIX that are robust alternatives to variance swaps.
我根据波动性指数SVIX得出了股票溢价的下限,该指数可以根据指数期权价格计算。这意味着股票溢价极不稳定,在2008年危机最严重的时候,它已经超过了20%。下界的时间序列平均值约为5%,这表明下界可能是近似紧的。我进行了预测回归,发现数据并未否定这一假设,因此我使用SVIX指数作为股票溢价的代表,并认为在压力时期可用的高股票溢价在很大程度上反映了短期内的高预期回报。我还提供了市场崩溃概率的衡量标准,并介绍了简单的方差互换,这是基于SVIX的可交易合约,是方差互换的稳健替代品。

We document the portfolio activity of federal housing agencies and provide evidence on its impact on mortgage markets and the economy. Through a narrative analysis, we identify historical policy changes leading to expansions or contractions in agency mortgage holdings. Based on those regulatory events that we classify as unrelated to short-run cyclical or credit market shocks, we find that an increase in mortgage purchases by the agencies boosts mortgage lending and lowers mortgage rates. Agency purchases influence prices in other asset markets and stimulate residential investment. Using information in GSE stock prices to construct an alternative instrument for agency purchasing activity yields very similar results as our benchmark narrative identification approach.
我们记录了联邦住房机构的投资组合活动,并提供了其对抵押贷款市场和经济影响的证据。通过叙述分析,我们确定了导致机构抵押贷款持有扩张或收缩的历史政策变化。基于那些我们归类为与短期周期性或信贷市场冲击无关的监管事件,我们发现,机构购买抵押贷款的增加促进了抵押贷款的发放,降低了抵押贷款利率。代理购买影响了其他资产市场的价格,刺激了住宅投资。使用GSE股票价格中的信息来构建代理购买活动的替代工具,其结果与我们的基准叙述识别方法非常相似。

The Mission: Human Capital Transmission, Economic Persistence and Culture in South America 使命:南美洲的人力资本传递、经济持续与文化

This article examines the long-term consequences of a historical human capital intervention. The Jesuit order founded religious missions in 1609 among the Guarani, in modern-day Argentina, Brazil, and Paraguay. Before their expulsion in 1767, missionaries instructed indigenous inhabitants in reading, writing, and various crafts. Using archival records, as well as data at the individual and municipal level, I show that in areas of former Jesuit presence—within the Guarani area—educational attainment was higher and remains so (by 10%–15%) 250 years later. These educational differences have also translated into incomes that are 10% higher today. The identification of the positive effect of the Guarani Jesuit missions emerges after comparing them with abandoned Jesuit missions and neighboring Franciscan Guarani missions. The enduring effects observed are consistent with transmission mechanisms of structural transformation, occupational specialization, and technology adoption in agriculture.
本文考察了历史上一次人力资本干预的长期后果。1609年,耶稣会在瓜拉尼人(位于今天的阿根廷、巴西和巴拉圭)中建立了宗教传教会。在1767年被驱逐之前,传教士教导土著居民阅读、写作和各种手工艺。我利用档案记录,以及个人和市政层面的数据表明,在瓜拉尼地区的前耶稣会存在的地区,受教育程度更高,并且在250年后仍然如此(10%-15%)。这些教育差异也转化为今天的收入高出10%。在将瓜拉尼耶稣会传教会与废弃的耶稣会传教会和邻近的方济各会瓜拉尼传教会进行比较后,我们发现了瓜拉尼耶稣会传教会的积极影响。观察到的持久效应与农业结构转型、职业专业化和技术采用的传导机制一致。

Lights, Camera … Income! Illuminating the National Accounts-Household Surveys Debate 灯光、相机……收入!照亮国民账户与家庭调查之争

GDP per capita and household survey means present conflicting pictures of the rate of economic development in emerging countries. One of the areas in which the national accounts–household surveys debate is key is the measurement of developing world poverty. We propose a data-driven method to assess the relative quality of GDP per capita and survey means by comparing them to the evolution of satellite-recorded nighttime lights. Our main assumption, which is robust to a variety of specification checks, is that the measurement error in nighttime lights is unrelated to the measurement errors in either national accounts or survey means. We obtain estimates of weights on national accounts and survey means in an optimal proxy for true income; these weights are very large for national accounts and very modest for survey means. We conclusively reject the null hypothesis that the optimal weight on surveys is greater than the optimal weight on national accounts, and we generally fail to reject the null hypothesis that the optimal weight on surveys is zero. Additionally, we provide evidence that national accounts are good indicators of desirable outcomes for the poor (such as longer life expectancy, better education and access to safe water), and we show that surveys appear to perform worse in developing countries that are richer and that are growing faster. Therefore, we interpret our results as providing support for estimates of world poverty that are based on national accounts. JEL Code: I32.
人均国内生产总值(GDP)和住户调查数据显示,新兴国家的经济发展速度相互矛盾。衡量发展中国家的贫困是国民核算与家庭调查之间争论的关键领域之一。我们提出了一种数据驱动的方法,通过将人均GDP和调查手段与卫星记录的夜间灯光的演变进行比较,来评估它们的相对质量。我们的主要假设是,夜间灯光的测量误差与国民账户或调查手段的测量误差无关,这对各种规格检查都是稳健的。我们获得了国民账户和调查手段在真实收入的最佳代理中的权重估计;这些权重对于国民账户来说非常大,对于调查手段来说非常小。我们最终拒绝了调查的最优权重大于国民账户的最优权重的零假设,我们通常不能拒绝调查的最优权重为零的零假设。此外,我们提供的证据表明,国民账户是穷人理想结果的良好指标(如更长的预期寿命、更好的教育和获得安全饮用水),我们还表明,在更富裕、增长更快的发展中国家,调查似乎表现得更差。因此,我们将我们的结果解释为为基于国民账户的世界贫困估计提供了支持。JEL代码:I32。

A Typology of Players: Between Instinctive and Contemplative 玩家的类型学:本能型和沉思型

A new typology of players is proposed based on the classification of actions as either instinctive or contemplative. A person’s type is the probability of him choosing a contemplative action. To test the typology, results of 10 games are analyzed. Actions in each game were classified depending on whether their response time was more or less, respectively, than the median response time of all subjects who played the game. It is argued that fast actions are more instinctive and slow actions are more contemplative. A subject’s contemplative index (CI) is defined as the proportion of games in which he chose a contemplative action. It is found that for 8 of the 10 games, the CI in the other 9 games is positively correlated with a player’s choice of a contemplative action in that game (average Spearman correlation of 9%). The CI is used to shed light on the nature of choice in five additional games. JEL Codes: C72, C91.
基于本能行为和沉思行为的分类,提出了一种新的玩家类型。一个人的类型是他选择沉思行为的概率。为了检验这一类型学,我们分析了10个游戏的结果。每个游戏中的行为都是根据他们的反应时间是比所有玩游戏的人的平均反应时间多还是少来分类的。有人认为,快速的行动更多的是本能的,而缓慢的行动更多的是沉思的。受试者的沉思指数(CI)被定义为他在游戏中选择沉思行为的比例。我们发现,在这10款游戏中,有8款游戏的CI与玩家在游戏中所选择的沉思行为呈正相关(平均Spearman相关性为9%)。CI用于阐明另外5款游戏中选择的本质。JEL代码:C72, C91。

Political Centralization and Government Accountability 政治集权和政府问责制

This article explains why decentralization can undermine accountability and answers three questions: what determines if power should be centralized or decentralized when regions are heterogeneous? How many levels of government should there be? How should state borders be drawn? We develop a model of political agency in which voters differ in their ability to monitor rent-seeking politicians. We find that rent extraction is a decreasing and convex function of the share of informed voters, because voter information improves monitoring but also reduces the appeal of holding office. As a result, information heterogeneity pushes toward centralization to reduce rent extraction. Taste heterogeneity pulls instead toward decentralization to match local preferences. Our model thus implies that optimal borders should cluster by tastes but ensure diversity of information. We also find economies of scope in accountability that explain why multiplying government tiers harms efficiency. A single government in charge of many policies has better incentives than many special-purpose governments splitting its budget and responsibilities. Hence, a federal system is desirable only if information varies enough across regions. JEL Codes: D72, D82, H73, H77.
本文解释了为什么权力下放会破坏问责制,并回答了三个问题:当地区异构时,是什么决定了权力应该集中还是分散?政府应该分为几级?国家边界应该如何划分?我们开发了一个政治代理模型,在这个模型中,选民监督寻租政客的能力各不相同。我们发现,租金提取是知情选民份额的递减和凸函数,因为选民信息提高了监督,但也降低了任职的吸引力。因此,信息异质性推动了集中化,以减少租金提取。口味的异质性反而会促使人们去中心化,以适应当地的偏好。因此,我们的模型表明,最优边界应该按品味聚类,但要确保信息的多样性。我们还发现,问责制中的范围经济解释了为什么政府层级的增加会损害效率。一个单一的政府负责许多政策比许多特殊目的的政府将其预算和责任分开有更好的激励。因此,联邦制只有在各地区信息差异足够大的情况下才可取。JEL代码:D72, D82, H73, H77。

Programs to encourage labor market activity among youth, including public employment programs and wage subsidies like the Work Opportunity Tax Credit, can be supported by three broad rationales. They may (i) provide contemporaneous income support to participants; (ii) encourage work experience that improves future employment and/or educational outcomes of participants; and/or (iii) keep participants "out of trouble." We study randomized lotteries for access to the New York City (NYC) Summer Youth Employment Program (SYEP), the largest summer youth employment program in the United States, by merging SYEP administrative data on 294,100 lottery participants to IRS data on the universe of U.S. tax records; to New York State administrative incarceration data; and to NYC administrative cause of death data. In assessing the three rationales, we find that (i) SYEP participation causes average earnings and the probability of employment to increase in the year of program participation, with modest contemporaneous crowdout of other earnings and employment; (ii) SYEP participation causes a modest decrease in average earnings for three years following the program and has no impact on college enrollment; and (iii) SYEP participation decreases the probability of incarceration and decreases the probability of mortality, which has important and potentially pivotal implications for analyzing the net benefits of the program.

鼓励年轻人参与劳动力市场活动的项目,包括公共就业项目和工作机会税收抵免(Work Opportunity Tax Credit)等工资补贴,可以从三个方面得到支持。他们可以(i)向参与者提供同期收入支持;(ii)鼓励参与者获得可改善其未来就业和/或教育成果的工作经验;和/或(iii)让参与者“远离麻烦”。我们研究了进入纽约市夏季青年就业计划(SYEP)的随机彩票,这是美国最大的夏季青年就业计划,通过将SYEP的294,100名彩票参与者的管理数据与美国国税局关于美国税务记录的数据合并;纽约州行政监禁数据;以及纽约市行政部门的死因数据在评估这三个基本原理时,我们发现(i)参与中小企业创业计划导致平均收入和就业概率在参与计划的那一年增加,同时适度地挤出其他收入和就业;(ii)参与中小企业项目会导致项目后三年的平均收入略有下降,对大学入学率没有影响;(iii)参与syev降低了被监禁的可能性,降低了死亡率,这对分析该计划的净收益具有重要的潜在关键意义。JEL代码:J13, J45, J38, J21。

Dynamic Selection: An Idea Flows Theory of Entry, Trade and Growth 动态选择:一种关于进入、贸易和增长的思想流动理论

This paper develops an idea flows theory of trade and growth with heterogeneous firms. New firms learn from incumbent firms, but the diffusion technology ensures entrants learn not only from frontier technologies, but from the entire technology distribution. By shifting the productivity distribution upwards, selection on productivity causes technology diffusion and this complementarity generates endogenous growth without scale effects. On the balanced growth path, the productivity distribution is a traveling wave with an increasing lower bound. Growth of the lower bound causes dynamic selection. Free entry mandates that trade liberalization increases the rates of technology diffusion and dynamic selection to offset the profits from new export opportunities. Consequently, trade integration raises long-run growth. The dynamic selection effect is a new source of gains from trade not found when firms are homogeneous. Calibrating the model implies that dynamic selection approximately triples the gains from trade relative to heterogeneous firm economies with static steady states.
本文提出了异质企业贸易与增长的思想流动理论。新公司向现有公司学习,但扩散技术确保进入者不仅学习前沿技术,而且学习整个技术分布。通过生产率分布的上移,对生产率的选择导致技术扩散,这种互补性产生内生增长,没有规模效应。在均衡增长路径上,生产率分布是一个下界不断增大的行波。下界的增长引起动态选择。自由进入要求贸易自由化增加技术扩散和动态选择的速度,以抵消新出口机会带来的利润。因此,贸易一体化提高了长期增长。动态选择效应是一种新的贸易收益来源,在企业同质化的情况下是找不到的。校准模型意味着,相对于具有静态稳定状态的异质企业经济,动态选择从贸易中获得的收益大约是三倍。

Learning from Inflation Experiences 从通胀经验中学习
IF 13.7 1区 经济学 Q1 ECONOMICS Pub Date : 2016-02-01 DOI: 10.1093/QJE/QJV037

How do individuals form expectations about future inflation? We propose that individuals overweight inflation experienced during their lifetimes. This approach modifies existing adaptive learning models to allow for age-dependent updating of expectations in response to inflation surprises. Young individuals update their expectations more strongly than older individuals since recent experiences account for a greater share of their accumulated lifetime history. We find support for these predictions using 57 years of microdata on inflation expectations from the Reuters/Michigan Survey of Consumers. Differences in experiences strongly predict differences in expectations, including the substantial disagreement between young and old individuals in periods of highly volatile inflation, such as the 1970s. It also explains household borrowing and lending behavior, including the choice of mortgages. JEL Codes: E03, G02, D03, E31, E37, D84, D83, D14.
个人如何形成对未来通胀的预期?我们认为个体在其一生中都经历过超重通货膨胀。这种方法修改了现有的自适应学习模型,允许根据年龄对预期进行更新,以应对通胀意外。年轻人比老年人更强烈地更新他们的期望,因为最近的经历在他们积累的一生历史中占据了更大的份额。我们使用路透/密西根消费者调查(Reuters/Michigan Survey of consumer) 57年来有关通胀预期的微观数据来支持这些预测。经历的差异强烈地预示着预期的差异,包括在高度波动的通货膨胀时期,如20世纪70年代,年轻人和老年人之间的巨大差异。它还解释了家庭借贷行为,包括抵押贷款的选择。JEL代码:E03, G02, D03, E31, E37, D84, D83, D14。
