We develop a non-cooperative bargaining model with incomplete information linking dowry payments, domestic violence, resource allocation between a husband and a wife, and separation. Our model generates several predictions, which we test empirically using amendments to the Indian anti-dowry law as a natural experiment. We document a decline in women's bargaining power and separations, and a surge in domestic violence following the amendments. These unintended effects are attenuated when social stigma against separation is low and, in some circumstances, when gains from marriage are high. Whenever possible, parents increase investment in their daughters' human capital to compensate for lower dowries.
我们建立了一个非合作讨价还价模型,该模型具有将嫁妆支付、家庭暴力、丈夫和妻子之间的资源分配以及分居联系起来的不完全信息。我们利用印度反嫁妆法修正案作为自然实验,对模型中的几项预测进行了实证检验。我们记录了修订后妇女议价能力和分居率的下降,以及家庭暴力的激增。当社会对分居的鄙视程度较低时,以及在某些情况下,当婚姻的收益较高时,这些意外影响就会减弱。只要有可能,父母就会增加对女儿人力资本的投资,以补偿较低的嫁妆。

This paper identifies productivity gains from trade by studying the manipulation behavior of firms in response to regulatory policies on international trade in China. Bunching estimates show that participation in international trade increases firm productivity. The productivity gains increase over time, indicating dynamic learning from trading. Further exploration shows no effects on R&D investment, product rationalization and markup. Young firms and nonstate-owned firms (non-SOEs) gain more from participating in trade. Workers share productivity gains through increased wages but not from increased employment.
本文通过研究中国企业在国际贸易监管政策下的操纵行为,确定贸易带来的生产率收益。捆绑估计结果显示,参与国际贸易提高了企业的生产率。生产率收益随时间推移而增加,表明企业从贸易中获得了动态学习。进一步的研究表明,对研发投资、产品合理化和加价没有影响。年轻企业和非国有企业从参与贸易中获益更多。工人通过增加工资分享生产率收益,而不是通过增加就业。

This paper estimates the returns to human capital accumulation during the first era of mega-firms in the United States by linking employees at General Electric—a canonical enterprise associated with the “visible hand” of managerial hierarchies—to the 1940 census. I find large returns to higher education through seniority in the hierarchy, span of control, earnings, and selection into management training, using the proximity of land-grant colleges and historical universities to birth states for identification. The findings highlight the human capital determinants of the managerial revolution at a prominent firm, driven by earlier public investments in the US education system.
本文通过将通用电气公司--一家与管理等级制度的 "看得见的手 "有关的典型企业--的员工与 1940 年的人口普查联系起来,估算了美国第一个巨型企业时代人力资本积累的回报。我利用赠地学院和历史悠久的大学与出生州的邻近程度进行识别,发现通过在等级制度中的资历、控制范围、收入和管理培训的选择,高等教育带来了巨大回报。研究结果凸显了一家知名企业管理革命的人力资本决定因素,而这一决定因素是由早期对美国教育系统的公共投资所推动的。

In the context of changing the demographic structure of the population (population aging) in order to determine the demand for goods and services and predict key socio-economic indexes, consumption age indexes are of practical interest for research. A feature of collecting information on the level of consumption is the conduct of surveys for the household as a whole, and not for a specific member of the household. At the same time, it should be noted that throughout the life cycle of a person, the level and structure of consumption differ. Methods for assessing the level of consumption in households of different generations are of greatest interest on the part of researchers. Current trends in developing and developed countries are characterized by a move away from multi-generational living. Thus, estimates of the level of consumption by children in households with parents are of practical interest.The purpose of the study. At present, there are no unequivocal recommendations on how to estimate the calculation of children’s consumption in households. At the same time, the available methods have been subjected to various criticisms from economists. It should be noted that most of the research on this topic was carried out at the end of the 20th century. At the same time, it is necessary to take into account possible cross-country features of consumption financing: the availability and development of medicine and education. If social services are available and provided at the expense of the state in a country, then the level of consumption by children will be lower. If the household finances the social sphere, the level of consumption by children in households will be higher. Thus, it is of practical interest to assess the level of consumption by children in Russian households.Materials and methods. Based on data from the Household Budget Survey (HBS) for 2020 conducted by Rosstat, households consisting of two adults and two adults with one child are selected. With the help of classical methods of statistical analysis, the construction of age profiles of consumption for each group of households is carried out. Based on the share of expenditures on food in the household and the scale effect of their consumption, the paper constructs age estimates for the redistribution of the level of consumption depending on the age of children. In addition, the sample size allows us to test the hypothesis about the age of birth of the child and the level of consumption.Results. The study made it possible to assess the differences in the level of consumption by children depending on the age at which a child was born. The average age of a child’s birth determines his/her further level of consumption throughout adulthood. Consumption is lowest among children who are born when parents are less than 26 years old. The obtained redistribution coefficients for ages under 15 are higher than in the estimates proposed by R. Lee, E. Mason, and Deaton, that confirms the possib
在人口结构发生变化(人口老龄化)的背景下,为了确定对商品和服务的需求,预测关键的社会经济指标,消费年龄指数的研究具有现实意义。收集消费水平资料的一个特点是对整个家庭进行调查,而不是对某一特定家庭成员进行调查。同时,应该注意到,在一个人的整个生命周期中,消费的水平和结构是不同的。研究人员最感兴趣的是评估不同世代家庭消费水平的方法。发展中国家和发达国家目前的趋势的特点是不再采用几代同宗的生活方式。因此,估计有父母家庭中儿童的消费水平是有实际意义的。研究的目的。目前,关于如何估算家庭儿童消费的计算,并没有明确的建议。与此同时,现有的方法也受到了经济学家的各种批评。需要指出的是,关于这一课题的研究大多是在20世纪末进行的。与此同时,有必要考虑到消费融资可能具有的跨国特征:医药和教育的可得性和发展。如果一个国家有社会服务,并且由国家出资提供,那么儿童的消费水平就会降低。如果家庭为社会领域提供资金,家庭中儿童的消费水平将会更高。因此,评估俄罗斯家庭中儿童的消费水平具有实际意义。材料和方法。根据俄罗斯国家统计局(Rosstat)进行的2020年家庭预算调查(HBS)的数据,选择了两个成年人和两个成年人有一个孩子的家庭。运用经典的统计分析方法,构建了各家庭群体的消费年龄谱。基于食品支出在家庭中的份额及其消费的规模效应,本文构建了基于儿童年龄的消费水平再分配的年龄估计。此外,样本量允许我们检验关于孩子出生年龄和消费水平的假设。结果。这项研究使人们有可能评估儿童在不同年龄出生时的消费水平差异。孩子出生的平均年龄决定了他/她成年后的消费水平。在父母年龄小于26岁时出生的孩子中,饮酒量最低。获得的15岁以下年龄的再分配系数高于R. Lee、E. Mason和Deaton提出的估计,这证实了俄罗斯家庭可能的消费模式。本文得出了两个关键结论。孩子出生的年龄决定了他/她未来的消费水平:24岁以下孩子的出生表明其整个成年期的消费水平相对较低。根据儿童的年龄对其消费水平所作的估计表明,在14岁以前的消费高于国外的方法,这可以用俄罗斯家庭的社会经济特征来解释。

Purpose of the study. In this paper, we consider the problem of negativity of weight coefficients when combining forecasts. Combining forecasts as a method has long ago proved itself in practice as a good way to improve forecast accuracy. However, in the literature little attention is paid to the issue of negative weights during aggregation, although the cases of obtaining such weights in practice are quite common. The reasons why this may happen are not considered or analyzed. Often, when obtaining weights less than zero, such weights are reset to zero, thus excluding the information contained in the particular forecasting method from the combination, which may reduce the accuracy of the combined forecast. In this regard, it is important to understand why when combining forecasts, negative weight can be obtained and determine options for how to avoid such situations in combining without losing accuracy.Materials and methods. It is proposed to consider various approaches to eliminate excluded weights when combining forecasts, including truncation of weight coefficients or imposing restrictions on them, including the option of sequential combining of forecasts. Results. The result is a list of reasons why negative weights can be obtained when combining forecasts, what risks they have and how to avoid them.Conclusion. Based on the results obtained, it can be concluded that the negative weights themselves when combining forecasts can be triggers for identifying problems when combining. However, it is dangerous to retain them, as they can lead to uncertain prediction results and degrade the accuracy of the resulting combined forecast. The proposed methods of work allow you to bypass the negativity of the weights without a strong deterioration in forecasting.
研究目的:本文考虑了组合预测时权系数的负性问题。结合预报作为一种方法,早已在实践中证明是提高预报准确性的好方法。然而,在文献中很少注意到在聚合过程中的负权问题,尽管在实践中获得负权的情况很常见。这种情况发生的原因没有被考虑或分析。通常,当获得的权重小于零时,这些权重被重置为零,从而将特定预测方法中包含的信息排除在组合之外,这可能会降低组合预测的准确性。在这方面,重要的是要理解为什么在组合预测时,可以获得负权重,并确定如何在不失去准确性的情况下避免组合这种情况的选择。材料和方法。建议在组合预测时考虑各种消除排除权重的方法,包括截断权重系数或对其施加限制,包括预测顺序组合的选项。结果。结果是一个清单的原因,为什么负权重可以获得时,结合预测,他们有什么风险,以及如何避免他们。根据得到的结果,可以得出结论,组合预测时的负权重本身可以作为组合时识别问题的触发器。然而,保留它们是危险的,因为它们可能导致不确定的预测结果,并降低最终组合预测的准确性。所提出的工作方法允许您绕过权重的负性,而不会导致预测的严重恶化。

Throughout the existence of mankind, the issues of human nutrition have been of daily relevance. With the development of statehood, their formulations have changed and since the beginning of the 21st century, tasks have been set to provide the population with food of their own production, to develop the reproductive process in agriculture, to achieve food self-sufficiency and independence.The purpose of the study. The purpose of the study is to determine the type of reproduction process in the current situation on the market of crop production in order to assess the level of food self-sufficiency of the population of the Irkutsk region with these products and to develop recommendations for their development.Materials and methods. Statistical methods were used in the paper: descriptive statistics, comparative analysis, dynamic series analysis, monographic and other research methods. The study uses normative, reference and statistical information. The empirical base of the study was made up of data from the Federal State Statistics Service, the Ministry of Agriculture of the Irkutsk region, accounting reports of agricultural organizations, publications in open sources. The object of the study is the supply of crop production in the Irkutsk region on the market.Results. The author’s approach in the study of the reproductive process and the agro-food market of crop production in the Irkutsk region, allowed to comprehensively analyze and determine: the type of reproduction of crop production, namely grain as expanded, potatoes and vegetables as narrowed; the main grain producers are peasant farms, potatoes and vegetables are households of the population; the level of self-sufficiency of the region with crop production, namely the region is self-sufficient with grain and potatoes; the level of food dependence of the region on imports, namely, the region is dependent on the import of vegetables; to identify the factors that influenced the formation of these indexes (natural and climatic, investment, reduction of the rural population, the prevailing eating behavior of the population of the region, etc.).Conclusion. Taking into account the results obtained, economic instability, high dynamics of changes in the external environment, the directions of formation and development of reproduction and agrifood market of crop production in the Irkutsk region are proposed, namely, for the development of grain production, it is necessary to organize and develop production of highly efficient machinery and technologies for processing; the development of potato growing requires significant investments in agricultural organizations and peasant farms for the purchase of equipment for planting, hilling, harvesting, etc., the construction of potato storage facilities, etc.; increasing the level of self-sufficiency with vegetables in the Irkutsk region is possible through the application of the experience of neighboring regions, the joint work of the state and agricultura

The object of the study is the dynamics of value indicators of the market of digital financial assets and digital currencies. The subject of the study is methods, models and algorithms for automated monitoring and management of digital financial assets and cryptocurrencies. The methodological basis of the research is formed by blockchain technologies, modeling and mathematical statistics methods, artificial intelligence methods. The statistical information base of the research is formed on the basis of the history of Tradingview’s value quotations from international trading exchanges of digital currencies, as well as by Coinmarketcap and Coingecko cryptoasset market integrators. Problems of modeling processes in economic systems are considered, the problem of optimal control is defined. A critical analysis of the state in the tasks of economic modeling is carried out, taking into account the uncertainty caused by social and psychological reasons.Results. The proposed methodology offers a comprehensive solution to the problem of managing digital financial assets and other financial instruments based on blockchain technology. Digital currencies act as the management object of the proposed methodology, the initial information is a vector of parameters that determine the sensitivity of the system to the perturbing influences of the external environment and the requirements for the expected management results.

Abstract Employment growth is one of the most crucial indicators for economic policy. Existing studies show that only a small fraction of firms experience high growth rates and create the most new jobs. Making use of recentered influence function regressions, this study examines the effects of process and product innovations on the employment growth distribution. The analysis is based on firm data from Eastern European countries. The effects of process innovation on job creation are ambiguous. An increase in firms with products and services that are new to the market shape the upper tail of the employment growth distribution. Product and service innovations thus cause skewness of the employment growth distribution and are a major determinant of job creation. This study therefore presents evidence on whether and how innovation activities affect employment growth and contributes to the lively debate about how to foster employment growth.
就业增长是经济政策最重要的指标之一。现有的研究表明,只有一小部分公司实现了高增长率,并创造了最多的新工作岗位。本研究利用重中心影响函数回归,探讨了工艺创新和产品创新对就业增长分布的影响。该分析基于东欧国家的可靠数据。流程创新对就业创造的影响是模糊的。拥有新产品和新服务的公司数量的增加形成了就业增长分布的上尾。因此,产品和服务创新导致就业增长分布不平衡,是创造就业机会的主要决定因素。因此,本研究提供了创新活动是否以及如何影响就业增长的证据,并有助于关于如何促进就业增长的激烈辩论。

How Does Takeover Competition Affect the Stock Performance of Targets and Acquirers? Evidence from the European Union 收购竞争如何影响目标公司和收购方的股票表现?来自欧盟的证据
IF 8 1区 经济学 Q1 ECONOMICS Pub Date : 2023-08-01 DOI: 10.1515/roe-2023-0058

Abstract We examine the impact of M&A announcements on stock prices of targets and acquirers in the European Union from 2002 to 2021. In line with the literature, we find strong positive returns for the target firms’ stocks, whereas returns are low or insignificant for the acquirers. We contribute to the literature by focusing on the effect of takeover competition and distinguishing between the returns of first and later bids. Accordingly, we confirm strong relationships between subsequent offers and target firms’ stock returns. These returns increase if a second order is made and if the premium related to the second offer is higher.
摘要本文研究了2002年至2021年欧盟并购公告对目标公司和收购方股价的影响。与文献一致,我们发现目标公司的股票有很强的正回报,而收购方的回报很低或微不足道。我们通过关注收购竞争的影响和区分第一次和后来的出价的回报来贡献文献。因此,我们确认后续报价与目标公司股票回报之间存在密切关系。如果第二笔订单和与第二笔报价相关的溢价更高,这些回报就会增加。

Land Titling and Sustainable Agricultural Practices in Vietnam 越南的土地所有权和可持续农业实践
IF 8 1区 经济学 Q1 ECONOMICS Pub Date : 2023-08-01 DOI: 10.1515/roe-2022-0071

Abstract This study quantifies the less salient yet important impacts of land titling on the adoption of sustainable agricultural practices (SAPs) in the context of Vietnam. Exploiting the within-plot variation in titling status, we find that land titling is positively associated with the implementation of SAPs. Specifically, being given formal titles to land makes Vietnamese rural households 6.58, 3.65, and 1.97 percentage points more likely to invest in soil-water conservation, adopt crop rotation, and leave the land fallow, respectively. These estimates represent increases of 8.7, 20.9, and 2 % compared to the sample averages, respectively. Given the substantial stress on the agricultural system generated by conventional farming, raising the adoption of SAPs could improve food security and alleviate hunger. Our findings also imply that strengthening land property rights through land titling can help us achieve sustainable development goals. The study calls for intensified policy efforts to make sure that formal land use certificates are issued for all farmlands.
摘要本研究量化了越南土地所有权对采用可持续农业实践(SAPs)的不太显著但重要的影响。利用土地所有权状况在地块内的变化,我们发现土地所有权与sap的实施呈正相关。具体来说,获得正式的土地所有权使越南农村家庭投资水土保持、采用作物轮作和休耕的可能性分别提高了6.58、3.65和1.97个百分点。与样本平均值相比,这些估价值分别增加了8.7、20.9和2% %。考虑到传统农业对农业系统造成的巨大压力,提高sap的采用可以改善粮食安全和减轻饥饿。我们的研究结果还表明,通过土地所有权加强土地产权可以帮助我们实现可持续发展目标。该研究呼吁加大政策力度,确保所有农田都获得正式的土地使用证。
