Trust is an essential element of individuals' willingness to engage in economic activity such as investment. Because cultural institutions influence individuals' trust, I examine whether shocks to trust in a prominent cultural institution have crossover effects on households' investment decisions. I employ the U.S. Catholic clergy abuse scandal from 2002 to 2006 as a plausibly exogenous shock to the Catholic Church. Using survey data, I find that Catholic households decrease their equity participation by 3.3% to 5.9% upon revelation of local clergy misconduct in the news, consistent with an economically sizable opportunity cost. Evidence points to the influence of Catholicism on local social norms as the main channel.
信任是个人愿意参与投资等经济活动的基本要素。由于文化机构会影响个人的信任,我研究了对知名文化机构的信任冲击是否会对家庭的投资决策产生交叉影响。我将2002年至2006年的美国天主教神职人员性侵丑闻视为对天主教会的外源性冲击。利用调查数据,我发现在当地神职人员不当行为在新闻中曝光后,天主教家庭的股权参与减少了3.3%至5.9%,这与经济上相当大的机会成本是一致的。有证据表明,天主教对当地社会规范的影响是主要渠道。

Diffusion Delay Centrality: Decelerating Diffusion Processes Across Networks 扩散延迟中心性:减缓跨网络的扩散过程
Pub Date : 2020-07-16 DOI: 10.2139/ssrn.3653030

This paper presents a methodology to identify agents who should be put into isolation to decelerate a diffusion process spreading through-out a network. We refer to this measure as to Diffusion Delay Centrality (DDC). We show that DDC assigns a high rank to agents acting as the gatekeepers of the fringe of the network. When these are isolated, the spreading of diffusion from the periphery to the core of the network (or vice versa) is prevented or, at least, decelerated. We also show that the ranking of nodes obtained from the DDC is predicted by standard measures of network centrality. Specifically, the ranking can be recovered using the difference in the values of betweenness and eigenvector centrality of network agents. We suggest that the findings presented in this paper might represent a useful tool for policies intending to reduce diffusion processes.
本文提出了一种方法来确定应该隔离的代理,以减缓扩散过程在整个网络中蔓延。我们把这种度量称为扩散延迟中心性(DDC)。我们表明,DDC给充当网络边缘守门人的代理分配了一个高级别。当这些被隔离时,扩散从外围到网络核心的扩散(反之亦然)被阻止或至少被减缓。我们还表明,从DDC获得的节点排名是通过网络中心性的标准度量来预测的。具体来说,可以使用网络代理之间值和特征向量中心性值的差异来恢复排名。我们认为,本文提出的研究结果可能为旨在减少扩散过程的政策提供有用的工具。

The Interbank Market Puzzle 银行间市场之谜
Pub Date : 2019-12-30 DOI: 10.2139/ssrn.3118363

This study documents significant differences in the interbank market lending and borrowing levels across countries. We argue that the existing differences in interbank market usage can be explained by the trust of the market participants in the stability of the country’s banking sector and counterparties, proxied by the history of banking crises and failures. Specifically, banks originating from a country that has lower level of trust tend to have lower interbank borrowing. Using a proprietary dataset on bilateral exposures, we investigate the Euro Area interbank network and find the effect of trust relies on the network structure of interbank markets. Core banks acting as interbank intermediaries in the network are more significantly influenced by trust in obtaining interbank funding, while being more exposed in a community can mitigate the negative effect of low trust. Country-level institutional factors might partially substitute for the limited trust and enhance interbank activity. JEL Classification: G01, G21, G28, D85
本研究记录了各国银行间市场借贷水平的显著差异。我们认为,银行间市场使用的现有差异可以用市场参与者对国家银行业和交易对手的稳定性的信任来解释,这是由银行危机和失败的历史所代表的。具体来说,来自一个信任度较低的国家的银行往往有较低的银行间借贷。使用专有的双边风险数据集,我们调查了欧元区银行间网络,并发现信任的影响依赖于银行间市场的网络结构。核心银行在网络中作为银行间中介机构,在获得银行间资金时受信任的影响更显著,而在社区中更多地暴露可以缓解低信任的负面影响。国家层面的制度因素可能会部分替代有限的信任,并增强银行间的活动。JEL分类:G01, G21, G28, D85

The Independence of Judges Reduced Legal Development in England, 1600-1800 法官的独立削弱了英国法律的发展(1600-1800)
Pub Date : 2018-10-04 DOI: 10.2139/ssrn.3260739

Conventional wisdom on English development confers iconic status on the clause of the Act of Settlement (1701) that mandated secure tenure for judges. Because the Act's effect on tenure was partial, the effect of tenure on judicial decisions can be identified. The paper estimates how the awarding of tenure changed the number of citations to judges' decisions, a measure of judicial quality. The empirics uses two new databases, one on judges' biographies and one recording citations in the English Reports to earlier decisions. Several strategies aid identification. A court-year panel permits difference-in-differences. Controls capture judges' human capital and the importance of litigation. Instrumental-variable estimates use judge life-expectancy and political vicissitudes as instruments. Tenure has a strong, significant, and deleterious effect on the quality of associate-judge decisions. Tenure has no effect for chief judges. The Act of Settlement reduces citations by 20% in the 18th century. The results are interpretable in terms of the incentives provided by a powerful legal profession that could protect vulnerable judges in a politically volatile era.
关于英国发展的传统智慧赋予1701年《殖民地法》(Act of Settlement)中规定法官终身任职的条款以标志性的地位。由于该法对任期的影响是部分的,因此可以确定任期对司法判决的影响。这篇论文估计了任期的授予如何改变了法官判决的引用次数,这是衡量司法质量的一个指标。这项实证研究使用了两个新的数据库,一个是法官的传记,另一个记录了《英语报告》中对早期判决的引用。几种策略有助于识别。一个法庭年度小组允许差异中的差异。控制抓住了法官的人力资本和诉讼的重要性。工具变量估计使用预期寿命和政治变迁作为工具。终身制对助理法官的判决质量有着强烈的、显著的、有害的影响。终身制对首席法官没有影响。《和解法案》在18世纪减少了20%的引用。这样的结果是可以解释的,因为在一个政治动荡的时代,强大的法律职业提供的激励可以保护脆弱的法官。

Restructuring the Chinese Freight Railway: Two Scenarios 中国货运铁路重组:两种情景
Pub Date : 2018-06-25 DOI: 10.2139/ssrn.3229378
Shana Cui, R. Pittman, Jian Zhao
Twenty years of debate regarding the restructuring of the Chinese freight railway have failed to yield a consensus. Early policy statements favoring the creation of above-the-rail competition over a monopoly infrastructure – the “European” model of rail restructuring – have broadened into a lively policy and scholarly debate that includes as an alternative the division of the system into competing vertically integrated railways – the “Americas” model of restructuring. To date, however, there have been no tangible reform steps beyond organizational restructuring, the construction of new coal railroads, some with private-sector participation, and the introduction of scheduled service, especially for containers, between China and Europe. In this paper we argue in favor of the Americas model as a basis for restructuring and offer two alternative scenarios for the creation of multiple vertically integrated freight railways. Both plans enable competition between independent firms and routes for import/export traffic, one a southern, One Belt/One Road path, the other a northern path via the Trans-Siberian Railway.
二十年来,关于中国货运铁路重组的争论未能达成共识。早期的政策声明倾向于在垄断基础设施上建立铁路上的竞争——“欧洲”铁路重组模式——已经扩大为一场活跃的政策和学术辩论,其中包括将铁路系统划分为相互竞争的垂直整合的铁路——“美洲”重组模式。然而,迄今为止,除了组织结构调整、建设新的煤炭铁路(其中一些铁路由私营部门参与)以及引入中欧之间的定期服务(特别是集装箱)之外,没有任何切实的改革措施。在本文中,我们支持将美洲模式作为重组的基础,并为创建多个垂直整合货运铁路提供了两种替代方案。这两个计划都允许独立公司和进出口交通路线之间的竞争,一个是南方的“一带一路”路线,另一个是通过西伯利亚大铁路的北方路线。

The South Caucasus states are engaged in a complex and contradictory process of simultaneous regional integration and disintegration. The main instrument of regional integration could be a network of bilateral Free Trade Agreements (FTA) which those countries have signed and adopted. As is well known, trade integration within a free trade area can also lead to trade diversion which may lead to a loss of tariff revenues although this should be less of a problem in the case of a low external tariff towards third countries.
南高加索各国正在进行区域一体化和解体同时进行的复杂和矛盾的进程。区域一体化的主要手段可以是这些国家签署和通过的双边自由贸易协定网络。众所周知,自由贸易区内的贸易一体化也可能导致贸易转移,这可能导致关税收入的损失,尽管在对第三国的外部关税较低的情况下,这应该不是一个问题。

Approaches to Defining and Measuring Russia’s Internet Economy 界定和衡量俄罗斯互联网经济的方法

Our study object is the Russian Internet economy, i.e. economic activities of companies relying on the Russian-language segment of the World Wide Web. The purpose of this study is to classify businesses engaged in the national Internet economy and measure its size (as a share of GDP) using official statistics. The analysis of international approaches used for such studies allowed us to classify these according to the following criteria: the direct impact of the Internet on the economy, indirect economic impact of the Internet, and its indirect impact on the social sphere. To assess the size of the Russian Internet economy we used the approaches applied by international organizations (OECD, BCG, McKinsey) for the analysis of the direct impact of the Internet on the economy [BCG (2014), McKinsey (2011), OECD (2014), etc.]. The authors singled out three sectors within the Internet economy: the sector of ICT infrastructure and its maintenance; the sector of companies doing business purely on the Internet, and the sector of companies combining an online and offline business. To assess the share of the Internet economy in GDP using the production approach we first defined the above sectors in accordance with All-Russian Classification of Economic Activities (OKVED) Rev. 1.1 and subsequently calculated gross value added (GVA) for each sector. For this purpose, the GVA data calculated by Federal Service of State Statistics (Rosstat) was disaggregated while the share of the GVA contributed by the third sector companies (i.e. combining an online and offline business) was assessed using the results of special surveys and Rosstat data. To measure the size of the Internet economy using the expenditure approach we focused on consumer spending on goods bought through the Internet, ICT equipment and Internet access as well as institutions’ expenditure for ICT equipment, fixed capital investment of enterprises engaged in Internet activities, public sector ICT spending, net exports of ICT goods and services. According to our estimates obtained by two methods such as the production approach and expenditure approach, the share of the Internet economy in GDP in 2014 amounted to 2.7 and 2.6%, respectively. Future studies would require a more detailed definition and description of the Internet-related economic activities on the basis of OKVED2 with subsequent calculation of GVA for appropriate companies as well as development of statistical tools for collecting data on household spending
我们的研究对象是俄罗斯的互联网经济,即依靠万维网俄语部分的公司的经济活动。本研究的目的是对从事国家互联网经济的企业进行分类,并使用官方统计数据衡量其规模(占GDP的份额)。通过对国际上用于此类研究的方法的分析,我们可以根据以下标准进行分类:互联网对经济的直接影响,互联网对经济的间接影响,以及互联网对社会领域的间接影响。为了评估俄罗斯互联网经济的规模,我们使用了国际组织(OECD, BCG,麦肯锡)用于分析互联网对经济的直接影响的方法[BCG(2014),麦肯锡(2011),经合组织(2014)等]。作者在互联网经济中挑出了三个部门:ICT基础设施及其维护部门;一种是纯粹在互联网上做生意的公司,另一种是线上线下结合的公司。为了使用生产方法评估互联网经济在GDP中的份额,我们首先根据全俄经济活动分类(OKVED) Rev. 1.1定义了上述部门,随后计算了每个部门的总增加值(GVA)。为此,联邦国家统计局(Rosstat)计算的GVA数据被分解,而第三部门公司(即结合在线和离线业务)贡献的GVA份额使用特殊调查结果和Rosstat数据进行评估。为了使用支出方法衡量互联网经济的规模,我们重点关注消费者通过互联网购买商品、ICT设备和互联网接入的支出,以及机构对ICT设备的支出、从事互联网活动的企业的固定资本投资、公共部门ICT支出、ICT商品和服务的净出口。根据我们采用生产法和支出法两种方法测算,2014年互联网经济占GDP的比重分别为2.7和2.6%。今后的研究将需要在OKVED2的基础上更详细地定义和描述与互联网有关的经济活动,随后为适当的公司计算GVA,并开发收集家庭支出数据的统计工具

The purpose of this study is to classify businesses engaged in the national Internet economy and measure its size (as a share of GDP) using official statistics. The analysis of international approaches used for such studies allowed us to classify these according to the following criteria: the direct impact of the Internet on the economy, indirect economic impact of the Internet, and its indirect impact on the social sphere. To assess the size of the Russian Internet economy we used the approaches applied by international organizations (OECD, BCG, McKinsey) for the analysis of the direct impact of the Internet on the economy [BCG (2014), McKinsey (2011), OECD (2014), etc.]. The authors singled out three sectors within the Internet economy: the sector of ICT infrastructure and its maintenance; the sector of companies doing business purely on the Internet, and the sector of companies combining an online and offline business. To assess the share of the Internet economy in GDP using the production approach we first defined the above sectors in accordance with All-Russian Classification of Economic Activities (OKVED) Rev. 1.1 and subsequently calculated gross value added (GVA) for each sector. For this purpose, the GVA data calculated by Federal Service of State Statistics (Rosstat) was disaggregated while the share of the GVA contributed by the third sector companies (i.e. combining an online and offline business) was assessed using the results of special surveys and Rosstat data. To measure the size of the Internet economy using the expenditure approach we focused on consumer spending on goods bought through the Internet, ICT equipment and Internet access as well as institutions’ expenditure for ICT equipment, fixed capital investment of enterprises engaged in Internet activities, public sector ICT spending, net exports of ICT goods and services. According to our estimates obtained by two methods such as the production approach and expenditure approach, the share of the Internet economy in GDP in 2014 amounted to 2.7 and 2.6%, respectively.

Population ageing requires adjustments to the traditional way of providing pensions though pay-as-you-go (PAYG) systems. Governments should prepare sound frameworks for a sustainable long-term shift towards private pensions, either in the form of second or third pillar or even better both of them. Namely, under demographic dynamics being driven by low fertility and increasing longevity both deteriorating the population's dependency ratio, private pension systems are more efficient than traditional PAYG. This paper makes two main points. First one is relatively straightforward. Fiscal limitations under current and projected demographic dynamics will dramatically reduce PAYG pensions. Without saving sufficient amounts during the active period, individuals will be increasingly ending up in poverty. Their savings will not be enough to support their desired old age consumption. Second point, highlights an impact of the asset allocation decision and related lacking awareness of general public regarding this issue. Under the assumption that people are literate enough and they save for their pensions, they might suffer opportunity losses because of the ignorance of appropriate allocation of their savings to various asset classes. Namely, we show in this paper there is a huge difference in outcomes under alternative asset allocation decisions. Those differences represent shortfalls in pension wealth. Therefore, we argue that both illiteracy about required saving on one hand and ignorance about the appropriate asset class decision on the other will play crucial role in determining well-being of masses in the not so distant future if the points we make in this paper are not taken to knowledge.
人口老龄化需要调整通过现收现付(PAYG)系统提供养老金的传统方式。政府应该为向私人养老金的可持续长期转变准备健全的框架,要么以第二支柱的形式,要么以第三支柱的形式,甚至最好是两者兼而有之。也就是说,在低生育率和寿命延长导致人口抚养比恶化的人口动态下,私人养老金制度比传统的现收现付制更有效。本文的主要观点有两点。第一个相对简单。当前和预计的人口动态下的财政限制将大大减少现收现付养老金。如果在活动期间没有足够的储蓄,个人将越来越多地陷入贫困。他们的储蓄将不足以支持他们所期望的老年消费。第二点,强调了资产配置决策的影响和相关的公众对这个问题的认识不足。假设人们有足够的文化,并为养老金储蓄,他们可能会遭受机会损失,因为他们不知道如何将储蓄适当地分配到各种资产类别。也就是说,我们在本文中表明,在不同的资产配置决策下,结果存在巨大差异。这些差异代表了养老金财富的不足。因此,我们认为,如果我们在本文中提出的观点不被理解为知识,那么一方面对所需储蓄的无知,另一方面对适当的资产类别决策的无知,将在不久的将来决定大众的福祉方面发挥关键作用。
