In the most recent decades, the economy has changed its relationship over time. Transactions tend to go faster and short-term behaviors have spread across the board. There is evidence that this phenomenon explains some aspects of the post-2008 crisis. In particular, the financial markets follow an extraordinary dynamic of acceleration that leads to a good part of the operations taking place in microseconds (something evident in what it has to do with high frequency trading systems). All this creates very important challenges for democratic politics as a whole, and above all, for the process of economic policiymaking. The crucial problem is that, although the latter have also tended to accelerate, they are systematically lagging behind the capital markets (that is, there is a dynamic of open desynchronization between politics and finance), which hinders their possibilities of achieving their goals. objectives effectively. All this forces us to rethink the role of lags, now turned into an element of the first order to advance in the definition of optimal policy. This article focuses on how the time pressure factor has exerted a notable impulse to some important institutional changes in the political-economic processes.
在最近的几十年里,随着时间的推移,经济关系发生了变化。交易往往进行得更快,短期行为已经全面展开。有证据表明,这一现象解释了2008年后危机的某些方面。特别是,金融市场遵循一种非同寻常的加速动态,这导致大部分操作在微秒内发生(这与高频交易系统有关)。所有这些都给整个民主政治,尤其是经济政策制定过程带来了非常重要的挑战。关键的问题是,尽管后者也有加速的趋势,但它们系统性地落后于资本市场(也就是说,政治和金融之间存在公开的去同步动态),这阻碍了它们实现目标的可能性。目标。所有这些都迫使我们重新思考滞后的作用,滞后现在已成为推进最优政策定义的首要因素。本文着重探讨了时间压力因素如何对政治经济进程中的一些重要制度变革产生显著的推动作用。

The article explores behavior features of different group of private investors on the Moscow and Saint Petersburg stock exchanges. It was found that the change in the size of the biggest group of registered broker clients on Moscow Exchange depended heavily on growth of real income and key characteristics of passive forms of income, such as deposit rates, government bond returns and stock dividend yield. Active broker clients on the Moscow stock exchange mainly focused on more speculative factors, such as equity premium, equity volatility, foreign stocks’ returns and exchange rate. The growth of individual investment accounts depended on factors of both active and speculative forms of income. The quantity of broker clients on Saint-Petersburg Exchange relied on an even wider set of factors, which included not only risk and returns on national markets, but also characteristics of foreign assets and exchange rates. The two Russian exchanges are interrelated. The bond and equity premium growth makes the national market more attractive than foreign assets. The expansion of private investors on the stock market in Russia, which began in 2018, is explained not only by a search for other investment instruments apart from deposits, especially under the ongoing decline in interest rates, but also by a growing interest in individual investment accounts. The latter represent a positive example of state influence on people’s savings through tax policy. Another factor of the raise of private investments was the implementation of modern investment platforms and active promotion of broker services by major banks. The financial crisis which begun in March 2020can become a serious challenge for millions of private investors who had opened accounts in the previous two years
本文探讨了莫斯科和圣彼得堡证券交易所不同群体的私人投资者的行为特征。研究发现,莫斯科交易所最大的注册经纪客户群体的规模变化在很大程度上取决于实际收入的增长和被动收入形式的关键特征,如存款利率、政府债券回报和股票股息收益率。莫斯科证券交易所活跃的经纪人客户主要关注更多的投机因素,如股票溢价、股票波动、外国股票的回报和汇率。个人投资账户的增长取决于积极和投机两种收入形式。圣彼得堡交易所的经纪人客户数量取决于更广泛的因素,不仅包括国内市场的风险和回报,还包括外国资产和汇率的特点。这两家俄罗斯交易所是相互关联的。债券和股票溢价的增长使得国内市场比外国资产更具吸引力。自2018年以来,俄罗斯股市上的私人投资者数量不断增加,这不仅是因为人们在寻找存款以外的其他投资工具,尤其是在利率持续下降的情况下,而且还因为人们对个人投资账户的兴趣日益浓厚。后者是国家通过税收政策影响人民储蓄的一个积极例子。民间投资增加的另一个因素是现代投资平台的实施和各大银行积极推广经纪业务。这场始于2020年3月的金融危机,可能会对过去两年开设账户的数百万私人投资者构成严峻挑战

This paper advances the proposition that economics, as a discipline, gives rewards that favor the “hard” and disfavor the “soft.” Such bias leads economic research to ignore important topics and problems that are difficult to approach in a “hard” way—thereby resulting in “sins of omission.” This paper argues for reexamination of current institutions for publication and promotion in economics—as it also argues for greatly increased tolerance in norms for publication and promotion as one way of alleviating narrow methodological biases. (JEL A11, B40)
本文提出了这样一个命题,即经济学作为一门学科,给予的奖励有利于“硬”,不利于“软”。这种偏见导致经济学研究忽视了难以“硬”处理的重要主题和问题,从而导致了“遗漏之罪”。“这篇论文主张重新审视经济学中当前的出版和推广制度,同时也主张大幅提高出版和推广规范的容忍度,以此来缓解狭隘的方法论偏见。(JEL A11,B40)

Cross-border data flows management and privacy protection are placed high in the international digital agenda due to unprecedented growth in the volume and pace of data collection, processing, storage and transfer globally. Despite the high importance of data flows regulation and its serious influence on all enterprises involved in digital economy, there is little research conducted in Russia and systemizing the national strategies in this sphere of regulation. The article provides an overview of the existing approaches of different countries to data protection, transfer (cross-border included) and storage, analyses the impact of regulation on international trade flows, and develops proposals for possible measures to reduce costs for companies in the digital age. The research discovers that today most countries of the world regulate personal data and other categories of sensitive data flows through the introduction of either a separate law or data protection provisions in the relevant sectoral laws. The countries’ approaches range from a complete ban on the cross-border transfer of all or certain categories of data to foreign countries to complete liberalization in this area. The most common approach is the introduction of one or several restrictions from the set of measures related to cross-border data transfers: data localization requirement; limitations on the number or type of countries to which sensitive data can be transferred without additional requirements; and the requirement of the personal data subject’s consent or responsible public authorities’ permission.
由于全球数据收集、处理、存储和传输的数量和速度空前增长,跨境数据流管理和隐私保护被置于国际数字议程的重要位置。尽管数据流监管具有高度重要性,并对所有参与数字经济的企业产生了严重影响,但在俄罗斯进行的研究很少,也很少对国家在这一监管领域的战略进行系统化。本文概述了不同国家在数据保护、传输(包括跨境)和存储方面的现有方法,分析了监管对国际贸易流动的影响,并提出了在数字时代降低公司成本的可能措施建议。研究发现,如今,世界上大多数国家都通过引入单独的法律或相关部门法律中的数据保护条款来监管个人数据和其他类别的敏感数据流。这些国家的做法从完全禁止向外国跨境转移所有或某些类别的数据到这一领域的完全自由化。最常见的做法是从与跨境数据传输有关的一系列措施中引入一项或多项限制:数据本地化要求;对无需额外要求即可将敏感数据转移到的国家数量或类型的限制;以及个人数据主体同意或主管公共当局许可的要求。

Optimization of Investment Portfolios Taking into Account the Behavioral Perception of Monetary Policy 考虑货币政策行为感知的投资组合优化

The paper presents an adaptation of modern behavioral economic theory to portfolio investment in the Russian stock market. The author analyzes the possibility of optimizing the investment portfolio for a private investor using portfolio correction based on changes in monetary policy indicators available in media sources. The behavioral model of portfolio selection is used, based on the value of shares on Moscow Exchange and taking into account a reference point in the theory of prospects in the form of indicators regulated by the Bank of Russia. The key rate and the standard of required reserves, inflation, the average rate on bank deposits, and the exchange rate of the US dollar to the ruble are used as monetary policy in­dicators. The behavioral model is a modified theory of average variance, in which the calculation of profitability and risk is carried out according to the main behavioral theories, namely the cumulative prospect and mental accounting theory. The author considers various options for forming a portfolio in accordance with the level of risk aversion. As a result of comparing the models of optimization of the average variance portfolio and the models based on the modified theory of average variance using behavioral factors, higher risk-return ratios of the modified models were revealed in the forecast period, while for the analyzed period all models were located on the line of Markowitz efficient portfolio. As a further development of the portfolio behavioral theory, the possibilities of adapting the model are proposed not only depending on the points of reference, but also de­pending on changes in risk acceptance coefficients and probability estimates.
本文将现代行为经济学理论应用于俄罗斯股市的投资组合。作者根据媒体来源的货币政策指标变化,分析了使用投资组合修正优化私人投资者投资组合的可能性。投资组合选择的行为模型基于莫斯科交易所的股票价值,并考虑到俄罗斯银行监管的指标形式的前景理论中的参考点。所需准备金的关键利率和标准、通货膨胀、银行存款平均利率以及美元对卢布的汇率被用作货币政策指标。行为模型是一种修正的平均方差理论,其中盈利能力和风险的计算是根据主要的行为理论,即累积前景和心理会计理论进行的。作者根据风险厌恶程度考虑了形成投资组合的各种选择。通过比较平均方差投资组合优化模型和基于行为因素平均方差修正理论的模型,发现修正模型在预测期内的风险收益率较高,而在分析期内,所有模型都位于Markowitz有效投资组合线上。作为投资组合行为理论的进一步发展,提出了调整模型的可能性,不仅取决于参考点,还取决于风险接受系数和概率估计的变化。

Analysis of Bank Default Factors in 2013–2019 2013-2019年银行违约因素分析

This paper studies bank defaults in the Russian Federation in recent years. Firstly, the Central Bank of Russia tightened prudential regulation in 2013. Secondly, a decrease in oil prices and economic sanctions resulted in a crisis in 2014–2015 with a huge depreciation of the national currency, which influenced the Russian banking sector substantially. Almost half of banks in Russia have been closed in the last 6 years. Through binary logistic models of bank defaults based on data for Q3 2013 through Q1 2019, the paper reveals the key factors which had an influence on the sustainability of Russian banks. The main result is that involvement in classical banking exposes banks to default risks. Excessive reserves appeared to be an important indicator of default as well. A special measure of liquidity creation was constructed. We found that high levels of liquidity creation increased the probability of bank failure. It is also worth mentioning that excessive liquidity creation put higher risks on a given bank in the crisis period. We can conclude that regulatory authorities should pay attention to high liquidity creators, especially in the group of small and medium-sized banks. We also found some evidence of an improvement in prudential regulation by the Bank of Russia. Separate models were estimated for the sample of 150 larger banks, which is more homogeneous and is of primary interest for the regulator. A number of variables, including the level of liquidity creation, turned out to be insignificant; however, high reserve values for possible losses still increase the probability of default to a large extent. Logistic panel regressions were also considered as an alternative specification.
本文研究了近年来俄罗斯联邦的银行违约情况。首先,俄罗斯中央银行在2013年收紧了审慎监管。其次,油价下跌和经济制裁导致2014-2015年的危机,国家货币大幅贬值,对俄罗斯银行业产生了重大影响。在过去6年中,俄罗斯几乎有一半的银行倒闭。通过基于2013年第三季度至2019年第一季度数据的银行违约二元逻辑模型,揭示了影响俄罗斯银行可持续性的关键因素。其主要结果是,参与传统银行业务会使银行面临违约风险。超额准备金似乎也是违约的一个重要指标。构建了一种创造流动性的特殊措施。我们发现,高水平的流动性创造增加了银行倒闭的可能性。同样值得一提的是,在危机时期,过度创造流动性会给特定银行带来更高的风险。我们可以得出结论,监管部门应该关注高流动性创造者,尤其是中小银行群体。我们还发现了一些证据,表明俄罗斯银行在审慎监管方面有所改善。对150家大型银行的样本进行了单独的模型估计,这些银行更为同质,也是监管机构的主要兴趣所在。包括流动性创造水平在内的一些变量被证明是微不足道的;然而,可能损失的高准备金值仍然在很大程度上增加了违约的可能性。逻辑面板回归也被认为是一种替代规范。

The Impact of Financial Information Comparability on Aggressive Tax Avoidance with Respect to the Information Environment 信息环境下财务信息可比性对激进避税的影响

The overall tax avoidance perspective suggests that managers who seek opportunities to avoid paying taxes are pursuing financial abuse by creating a lack of transparency in the financial reporting environment. It seems that many companies are involved in tax avoidance. For this reason, it is crucial to determine the factors influencing the rate of tax avoidance. In this study, it is assumed that, in weak information environments, there is much incentive to avoid paying taxes. Thus, in this research, the effect of financial information comparability on aggressive tax avoidance with respect to the information environment has been investigated. To this end, 88 companies were examined during the period from 2011 to 2016. The required financial information was extracted by referring to the financial statements using Rahavard Novin software; summarized, classified and calculated in Excel software; and finally, analyzed through EViews software. By using the combined data and taking advantage of the generalized least squares regression test, it was established that the impact of financial statement comparability on aggressive tax avoidance in companies with a weaker information environment was more significant at a 90% confidence level. On the other hand, in a situation where there is a weak information environment, the ability to compare financial statements plays a significant role in reducing tax avoidance. Thus, it can reduce companies’ involvement in avoiding daring taxes, especially in a weak information environment. Furthermore, no reliable evidence was found concerning the effectiveness of financial information comparability in aggressive tax avoidance at a 95% confidence level.
总体避税观点表明,寻求避税机会的管理者正在通过在财务报告环境中缺乏透明度来追求财务滥用。看来许多公司都在避税。因此,确定影响避税率的因素至关重要。在这项研究中,假设在薄弱的信息环境中,有很多避免纳税的动机。因此,在本研究中,就信息环境而言,研究了财务信息可比性对激进避税的影响。为此,在2011年至2016年期间,对88家公司进行了检查。所需的财务信息是通过使用Rahavard Novin软件参考财务报表提取的;在Excel软件中进行汇总、分类和计算;最后通过EViews软件进行分析。通过使用组合数据并利用广义最小二乘回归检验,确定在90%的置信水平下,财务报表可比性对信息环境较弱的公司积极避税的影响更为显著。另一方面,在信息环境薄弱的情况下,比较财务报表的能力在减少避税方面发挥着重要作用。因此,它可以减少公司逃避大胆税收的参与,尤其是在信息环境薄弱的情况下。此外,在95%的置信水平下,没有发现关于财务信息可比性在积极避税中的有效性的可靠证据。

Furthermore, no reliable evidence was found concerning the effectiveness of financial information comparability in aggressive tax avoidance at a 95% confidence level.","PeriodicalId":43996,"journal":{"name":"Ekonomicheskaya politika","volume":" ","pages":""},"PeriodicalIF":0.5,"publicationDate":"2020-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49097691","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}

We studied the specific properties of the cryptocurrency market. Guided by the concept of implied volatility, we investigated the asymmetric reaction of the market to news. Based on the concept of realized volatility, we verified the hypothesis of herding behavior in the market. To test the properties of the market, we used a combination of methods, starting from the analysis of statistics of search queries, interpreted as proxies of information demand from professional market participants and the “wide crowd”, and ending with advanced Markov-Switching GARCH models and heterogeneous autoregressive models of realized volatility (HAR-RV-J-models). As a result, we found various types of asymmetric reactions of the cryptocurrency market to news related to both the general direction of its dynamics (growth or decrease) and the amplitude of return fluctuations (high or low volatility). During the upward price rally and overheating of the market, investors deliberately avoided the bad news; thereby the asymmetry in the cryptocurrency market was inverse (to the adopted leverage effect). On the contrary, during the downward price rally, market participants exhibited an overreaction to bad news. In addition, the asymmetric reaction to the news observed during the period of low market volatility actually disappeared when the amplitude of cryptocurrency return volatility increased. The behavior of short-term investors was also varied in the study period. While during the growth of the market, small speculators were more likely to follow their own trading strategies, during the hype they borrowed the trading practices of the largest players. We also revealed the effect of training among small investors: over time, they became less prone to provocations from large players, which did not allow the 2019 rally to surpass its counterpart in 2017 in terms of both return oscillations and duration.
我们研究了加密货币市场的具体属性。在隐含波动率概念的指导下,我们研究了市场对新闻的不对称反应。基于已实现波动率的概念,我们验证了市场羊群行为的假设。为了测试市场的性质,我们使用了多种方法的组合,从分析搜索查询的统计数据开始,将其解释为专业市场参与者和“广泛人群”的信息需求的代理,到高级马尔可夫切换GARCH模型和实现波动性的异构自回归模型(HAR-RV-J模型)结束。因此,我们发现加密货币市场对与其动态的总体方向(增长或下降)和回报波动幅度(高或低波动)有关的新闻的各种类型的不对称反应。在价格上涨和市场过热期间,投资者有意避开坏消息;因此加密货币市场的不对称性与所采用的杠杆效应相反。相反,在价格下跌的涨势中,市场参与者对坏消息反应过度。此外,在市场低波动期观察到的对消息的不对称反应实际上在加密货币回报波动幅度增加时消失了。短期投资者的行为在研究期间也有所不同。虽然在市场增长期间,小投机者更有可能遵循自己的交易策略,但在炒作期间,他们借鉴了最大参与者的交易做法。我们还揭示了培训对小投资者的影响:随着时间的推移,他们不太容易受到大投资者的挑衅,这使得2019年的反弹在回报波动和持续时间方面都没有超过2017年的反弹。

School choice during a period of radical school reform. Evidence from academy conversion in England 激进的学校改革时期的学校选择。来自英格兰学院转变的证据

We study how demand responds to the rebranding of existing state schools as autonomous ‘academies’ in the context of a radical and large-scale reform to the English education system. The academy programme encouraged schools to opt out of local state control and funding, but provided parents and students with limited information on the expected benefits. We use administrative data on school applications for three cohorts of students to estimate whether this rebranding changes schools’ relative popularity. We find that families – particularly higher income, White British – are more likely to rank converted schools above non-converted schools on their applications. We also find that it is mainly schools that are high-performing, popular and proximate to families’ homes that attract extra demand after conversion. Overall, the patterns we document suggest that families read academy conversion as a signal of future quality gains – although this signal is in part misleading as we find limited evidence that conversion causes improved performance.
我们研究了在对英国教育体系进行激进和大规模改革的背景下,现有公立学校更名为自主“学院”的需求是如何反应的。该学院计划鼓励学校选择不受地方政府的控制和资助,但对家长和学生提供的预期收益信息有限。我们使用了三组学生申请学校的行政数据来估计这种品牌重塑是否会改变学校的相对受欢迎程度。我们发现,家庭——尤其是高收入的英国白人——在申请时更有可能把改造过的学校排在非改造过的学校前面。我们还发现,主要是那些表现优异、受欢迎、离家近的学校在改造后吸引了额外的需求。总的来说,我们记录的模式表明,家庭将转学视为未来质量提高的信号——尽管这种信号在一定程度上是误导性的,因为我们发现有限的证据表明转学导致了成绩的提高。

What drives pension reforms in the OECD? 是什么推动了经合组织的养老金改革?

Based on narrative identification, we construct a novel comprehensive dataset of pension reform measures in OECD countries from 1970 to 2017. We then study the timing of these measures. Our main and new result is that business cycle indicators are important for their timing: a worsening makes contractionary measures more likely and expansionary measures less likely. The demography matters only in the sense that the OECD-wide demography explains the general reform trend for a country. We find no evidence that country-specific or short-run demographic developments matter. We discuss a conceptual framework with adjustment costs of changing pension generosity that can account for both the reform responsiveness to the business cycle and the lack of responsiveness to changes in demographic forecasts. We also discuss potential policy implications of our findings.
在叙事识别的基础上,我们构建了一个新颖的综合数据集,涵盖1970年至2017年经合组织国家的养老金改革措施。然后我们研究这些措施的时机。我们最新的主要结论是,商业周期指标在时机上很重要:经济恶化更有可能采取紧缩措施,而扩张性措施的可能性更小。只有在经合组织范围内的人口统计能够解释一个国家的总体改革趋势时,人口统计才有意义。我们没有发现任何证据表明具体国家或短期的人口发展很重要。我们讨论了一个概念框架,其中包含养老金慷慨度变化的调整成本,该框架可以解释改革对商业周期的响应性和对人口预测变化的缺乏响应性。我们还讨论了研究结果的潜在政策含义。
