Russian Abstract: В данном исследовании проводится анализ предсказательной способности такого типа интернет данных, как интенсивность поисковых запросов, для прогнозирования инфляции, уровня безработицы, реальных темпов роста ВВП и курса рубля к доллару в период с января 2004 г. по июль 2019 г. В работе используются поисковые запросы, связанные с финансовыми рынками, инфляционными ожиданиями и макроэкономическими условиями. Результаты показывают, что включение в модель интенсивностей поисковых запросов позволяет повысить точность прогнозов инфляции, уровня безработицы и курса рубля к доллару по сравнению с наивным прогнозом.

English Abstract: This study examines the usefulness of Google Trends intensity search queries data as a measure of economic expectations in predicting inflation, unemployment, real gdp growth and exchange rate during the period between January 2004 and July 2019. We use search queries related to financial markets, inflation expectations and macroeconomic conditions. The results show that the addition of Google search queries improveы out-of-sample forecasts of inflation, unemployment and exchange rate over naïve forecast.

Russian Abstract: В данной работе разрабатывается и апробируется методика построения вероятностного многорегионального демографического прогноз России до 2050 г. Согласно прогнозу к 2050 медианная численность составит 134,9 млн человек при 90% доверительном интервале от 125,8 млн до 147,4 млн человек. Медианный возраст возрастает с 39,4 лет в 2019 г. до 44,3 лет (41,7 – 47,8) в 2050 г. Однако перспективный медианный возраст (оцененный к базовому 2018 г.) растет до 39,8 (33,7–43,8). Полученные нами оценки показывают, что оптимистические сценарии демографического развития, это сценарии наиболее оптимистических 5-10% из анализируемых нами, демографических траекторий.

English Abstract: In this work, we develop and test a methodology for constructing a probabilistic multi-regional demographic forecast of Russia until 2050. According to the forecast, by 2050 the median population will be 134.9 million people with a 90% confidence interval from 125.8 million to 147.4 million people. The median age increases from 39.4 years in 2019 to 44.3 years (41.7 - 47.8) in 2050, however, the promising median age (estimated by the base year 2018) grows to 39.8 (33, 7–43.8). Our estimates show that the optimistic scenarios of demographic development are the scenarios of the most optimistic 5-10% of the demographic trajectories that we analyze.

What Will Be the Economic Impact of Covid-19 in the Us? Rough Estimates of Disease Scenarios 新冠肺炎对美国的经济影响是什么?疾病情景的粗略估计

This note is intended to introduce economists to a simple SIR model of the progression of COVID-19 in the United States over the next 12-18 months. An SIR model is a Markov model of the spread of an epidemic in a population in which the total population is divided into categories of being susceptible to the disease (S), actively infected with the disease (I), and recovered (or dead) and no longer contagious (R). How an epidemic plays out over time is determined by the transition rates between these three states. This model allows for quantitative statements regarding the tradeoff between the severity and timing of suppression of the disease through social distancing and the progression of the disease in the population. Example applications of the model are provided. Special attention is given to the question of if and when the fraction of active infections in the population exceeds 1% (at which point the health system is forecast to be severely challenged) and 10% (which may result in severe staffing shortages for key financial and economic infrastructure) as well as the cumulative burden of the disease over an 18 month horizon.
本文旨在向经济学家介绍未来12-18个月美国COVID-19进展的简单SIR模型。SIR模型是流行病在人群中传播的马尔可夫模型,其中总人口被分为易感染疾病(S)、积极感染疾病(I)和恢复(或死亡)且不再具有传染性(R)的类别。流行病如何随着时间的推移而发挥作用取决于这三种状态之间的过渡率。该模型允许对通过社会距离抑制疾病的严重程度和时间与疾病在人群中的进展之间的权衡进行定量陈述。给出了该模型的应用实例。特别关注人群中活动性感染比例是否以及何时超过1%(届时预计卫生系统将面临严重挑战)和10%(届时可能导致关键财政和经济基础设施人员严重短缺)的问题,以及18个月期间该病的累积负担。

Gender Roles and the Gender Expectations Gap 性别角色和性别期望差距
Pub Date : 2020-02-29 DOI: 10.2139/ssrn.3797091
Francesco D’Acunto, Ulrike Malmendier, Michael Weber
Expectations about macro-finance variables, such as inflation, vary significantly across genders, even within the same household. We conjecture that traditional gender roles expose women and men to different economic signals in their daily lives, which in turn produce systematic variation in expectations. Using unique data on the contributions of men and women to household grocery chores, their resulting exposure to price signals, and their inflation expectations, we show that the gender expectations gap is tightly linked to participation in grocery shopping. We also document a gender gap in other economic expectations and discuss how it might affect economic choices.
对宏观金融变量(如通货膨胀)的预期在性别之间存在显著差异,即使在同一家庭内也是如此。我们推测,传统的性别角色使女性和男性在日常生活中接触到不同的经济信号,这反过来又产生了期望的系统性差异。我们使用了关于男性和女性对家庭杂货杂事的贡献、他们对价格信号的影响以及他们的通胀预期的独特数据,表明性别预期差距与参与杂货购物密切相关。我们还记录了其他经济预期中的性别差距,并讨论了它如何影响经济选择。

Grouping Individual Investment Preferences in Retirement Savings: A Cluster Analysis of a USS Members Risk Attitude Survey 个人退休储蓄投资偏好分组:美国会员风险态度调查的聚类分析
Pub Date : 2020-02-01 DOI: 10.2139/ssrn.3552251

Cluster analysis is used to identify homogeneous groups of members of USS in terms of risk attitudes. There are two distinct clusters of members in their 40s and 50s. One had previously ‘engaged’ with USS by making additional voluntary contributions. It typically had higher pay, longer tenure, less interest in ethical investing, lower risk capacity, a higher percentage of males, and a higher percentage of academics than members of the ‘disengaged’ cluster. Conditioning only on the attitude to risk responses, there are 18 clusters, with similar but not identical membership, depending on which clustering method is used. The differences in risk aversion across the 18 clusters could be explained largely by differences in the percentage of females and the percentage of couples. Risk aversion increases as the percentage of females in the cluster increases, while it reduces as the percentage of couples increases because of greater risk sharing within the household. Characteristics that other studies have found important determinants of risk attitudes, such as age, income and (pension) wealth, do not turn out to be as significant for USS members. Further, despite being on average more highly educated than the general population, USS members are marginally more risk averse than the general population, controlling for salary, although the difference is not significant.
聚类分析是用来确定在风险态度方面的USS成员的同质组。40多岁和50多岁的成员组成了两个截然不同的群体。其中一人此前曾通过提供额外的自愿捐款与USS“签约”。与“不参与”集群的成员相比,它通常有更高的薪酬、更长的任期、对道德投资的兴趣较少、更低的风险承受能力、更高的男性比例和更高的学者比例。仅以对风险反应的态度为条件,有18个集群,根据使用哪种聚类方法,具有相似但不相同的隶属关系。在18个群体中,风险厌恶程度的差异很大程度上可以用女性比例和夫妻比例的差异来解释。风险厌恶随着集群中女性比例的增加而增加,而由于家庭内部风险分担的增加,风险厌恶随着夫妻比例的增加而减少。其他研究发现风险态度的重要决定因素,如年龄、收入和(养老金)财富等特征,对USS成员来说并不重要。此外,尽管平均受教育程度高于一般人群,但在控制工资的情况下,USS成员的风险厌恶程度略高于一般人群,尽管差异并不显著。

School Effects on Socio-Emotional Development, School-Based Arrests, and Educational Attainment 学校对社会情感发展、校本逮捕和教育成就的影响

Using value-added models on data from Chicago Public Schools, we find that high schools impact students' self-reported socioemotional development (SED) by enhancing social well-being and promoting hard work. Conditional on their test score impacts, schools that improve SED in ninth grade reduce school-based arrests and increase high school completion and college going. For most longer-run outcomes, using both SED and test score value added more than doubles the variance of the explained school effect relative to using test score value added alone. Results suggest that high school impacts on SED can be captured using self-report surveys and SED can be fostered by schools to improve longer-run outcomes. (JEL I21, J24, K42)
利用芝加哥公立学校数据的增值模型,我们发现高中通过提高社会幸福感和促进努力学习来影响学生自我报告的社会情感发展(SED)。根据测试成绩的影响,提高九年级学生SED的学校减少了学校的逮捕,提高了高中毕业率和大学入学率。对于大多数长期结果来说,使用SED和考试分数值增加的解释学校效应的方差是单独使用考试分数值增加的两倍多。研究结果表明,高中对SED的影响可以通过自我报告调查来捕捉,学校可以培养SED以改善长期结果。(j21, j24, k42)

Nigerian Female Immigrant Entrepreneurs within the Service Industry in New York City, USA: An Integrative Literature Review 美国纽约市服务业的奈及利亚女移民企业家:综合文献回顾
Pub Date : 2020-01-31 DOI: 10.2139/ssrn.3529631
Dr. Tiffany Oloke, D. Halkias
Africans are categorized as one of the largest ethnic groups in the world noted for migration, while Nigeria is the most abundant migrating country within the African continent. The problem is that little is known about the business experiences of Nigerian, female, immigrant entrepreneurs within the service industry in New York. These entrepreneurs face problems in starting a business and adapting to the social and institutional environment of the host country. This integrative literature review is part of a more extensive quantitative multiple-case study on the barriers faced by Female Nigerian immigrant who owns their service businesses in New York City. Research results indicate even though they vary, there are significant barriers such as safety and security, gender inequality, certain levels of ethnic and non-ethnic competition, stereotyping, globalization, cultural adaptation (language, religion, way of dressing) are significant problems facing Nigerian, female, immigrant entrepreneurs in New York. This research overview will be a manual for upcoming Nigerian female immigrant entrepreneurs coming to establish their businesses in New York.
非洲人被归类为世界上最大的移民群体之一,而尼日利亚是非洲大陆上移民人数最多的国家。问题在于,人们对纽约服务业的尼日利亚女性移民企业家的经商经历知之甚少。这些企业家在开办企业和适应东道国的社会和体制环境方面面临问题。这项综合文献综述是一项更广泛的定量多案例研究的一部分,该研究针对在纽约市拥有服务业务的尼日利亚女性移民所面临的障碍。研究结果表明,尽管他们各不相同,但存在重大障碍,如安全和保障,性别不平等,一定程度的种族和非种族竞争,刻板印象,全球化,文化适应(语言,宗教,着装方式)是纽约尼日利亚女性移民企业家面临的重大问题。这项研究概述将是一本手册,为即将到来的尼日利亚女性移民企业家来建立自己的业务在纽约。

Aging Labor, ICT Capital, and Productivity in Japan and Korea 日本和韩国的老龄化劳动力、ICT资本和生产率
Pub Date : 2020-01-14 DOI: 10.2139/ssrn.3518875

This study examines how aging affects labor productivity using industry-level data of Japan and Korea. The analysis shows that, for both Japan and Korea, aging has positive effects on labor productivity when older workers are working in industries with a large share of information and communication technology (ICT) in the capital stock. We also find that, on average, older workers exert positive effects on labor productivity across all industries when they are low-educated in Japan and high-educated in Korea. In addition, a complementary effect between ICT capital and older workers is observed for both high- and low-educated workers in Japan but only for low-educated workers in Korea. We discuss the interplay among educational attainment, industry characteristics, and production techniques to explain the differences between the two countries in the productivity of their older workers.
本研究利用日本和韩国的产业数据,探讨老龄化对劳动生产率的影响。分析结果显示,对于日本和韩国来说,高龄劳动者在资本存量中信息通信技术(ICT)比重较大的行业工作时,老龄化对劳动生产率产生了积极影响。我们还发现,平均而言,日本受教育程度低、韩国受教育程度高的老年工人对所有行业的劳动生产率都有积极影响。此外,信息通信技术资本与老年工人之间的互补效应在日本的高学历和低学历工人中都存在,但在韩国只存在于低学历工人中。我们讨论了教育程度、行业特征和生产技术之间的相互作用,以解释两国老年工人生产率的差异。

We discuss the interplay among educational attainment, industry characteristics, and production techniques to explain the differences between the two countries in the productivity of their older workers.","PeriodicalId":149805,"journal":{"name":"Labor: Demographics & Economics of the Family eJournal","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-01-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125089237","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 develop a theoretical model for the intra-household allocation of time and consumption that distinguishes between partners’ joint and private leisure. Estimating the model using time-use data leads to five findings. First, the intra-household expenditure distribution correlates with relative wages, consistent with the collective model. Second, men put relatively more weight on private expenditure and composite leisure. Third, joint and private leisure are imperfect substitutes. Fourth, joint and private leisure are independent of the wage distribution, suggesting that togetherness does not substitute for economic factors. Fifth, higher female wages imply higher childcare hours for women, but lower for men.
我们开发了一个家庭内部时间和消费分配的理论模型,该模型区分了伴侣的共同休闲和私人休闲。使用时间使用数据对模型进行估计,有五个发现。首先,家庭内部支出分配与相对工资相关,符合集体模型。其次,男性相对更注重私人消费和综合休闲。第三,联合休闲和私人休闲是不完美的替代品。第四,共同休闲和私人休闲与工资分配无关,这表明团聚并不能替代经济因素。第五,女性工资的提高意味着女性育儿时间的增加,而男性育儿时间的减少。

Women's Labor Force Participation and Household Technology Adoption 妇女劳动力参与与家庭技术采用
Pub Date : 2020-01-08 DOI: 10.2139/ssrn.3520613
G. Bose, Tarun Jain, Sarah Walker
We examine how women's employment leads to household technology adoption in the context of mid-century United States. We posit that this relationship is strongest for households with low earning capacity whose consumption-leisure tradeoff crosses a threshold as women go to work. Using WWII factories to instrument for female labor demand, we find that a standard deviation increase in female labor force participation increases washing machine ownership by 0.44 standard deviations, which is driven primarily by counties in the lowest pre-war education quintile. Changes to household income, as well as the substitution of paid domestic labor with appliances, are important channels.
我们研究如何妇女的就业导致家庭技术采用的背景下,本世纪中叶的美国。我们假设,这种关系在低收入家庭中最为强烈,这些家庭的消费-休闲权衡跨越了一个阈值,因为女性去工作。使用二战工厂来测量女性劳动力需求,我们发现女性劳动力参与率的标准差增加会使洗衣机拥有量增加0.44个标准差,这主要是由战前教育水平最低的五分之一的县推动的。家庭收入的变化,以及家用电器取代有偿家务劳动,都是重要的渠道。
