We study the productivity level distributions of manufacturing firms in France and Germany, and how these distributions evolved across the Great Recession. We show the presence of a systematic productivity advantage of German firms over French ones in the decade 2003-2013, but the gap has narrowed down after the Great Recession. Convergence is explained by the better growth performance of French firms in the post-recession period, especially of those located in the top percentiles of the productivity distribution. We also highlight the role of sectoral growth, firm size and export intensity in explaining the above convergence. In contrast, the contribution of allocative efficiency was small.
我们研究了法国和德国制造业企业的生产率水平分布,以及这些分布在大衰退期间是如何演变的。我们展示了2003-2013年间,德国企业相对于法国企业存在系统性的生产率优势,但在大衰退之后,这种差距缩小了。趋同现象可以用法国公司在经济衰退后的增长表现来解释,尤其是那些位于生产率分布前百分位数的公司。我们还强调了部门增长、企业规模和出口强度在解释上述趋同中的作用。相比之下,配置效率的贡献较小。

Mechanism Design for Unequal Societies 不平等社会的机制设计
Pub Date : 2020-09-07 DOI: 10.2139/ssrn.3688376
Marco Reuter, Carl-Christian Groh
We study optimal mechanisms for a utilitarian designer who seeks to assign multiple units of an indivisible good to a group of agents with unit demand. The agents have heterogeneous marginal utilities of money, which implies that utility is not perfectly transferable between them. Heterogeneous marginal utilities of money may naturally arise in environments where agents have different wealth endowments. We show that the ex post efficient allocation rule is not optimal in our setting. Firstly, a high willingness to pay may stem from a low marginal utility of money. Moreover, the transfer rule does not only facilitate implementation of the desired social choice function in our setting, but also directly affects social welfare. In the optimal mechanism, rationing may occur, which entails a conflict between ex ante and ex post efficiency. In an extension, we show that it is still not utilitarian optimal to allocate the good solely based on willingness to pay even when redistribution is not possible. Finally, we highlight how our mechanism can be implemented as an auction with minimum bids and bidding subsidies.
我们研究了功利主义设计师的最优机制,他们寻求将多个单位的不可分割商品分配给具有单位需求的一组代理。代理人具有异质的货币边际效用,这意味着效用在他们之间不是完全可转移的。在代理人拥有不同财富禀赋的环境中,货币的异质边际效用可能自然产生。我们表明事后有效分配规则在我们的设置中不是最优的。首先,高支付意愿可能源于货币的低边际效用。此外,在我们的设置中,转移规则不仅促进了所期望的社会选择函数的实现,而且直接影响到社会福利。在最优机制下,可能会出现配给制,这就导致了事前效率和事后效率的冲突。在一个扩展中,我们表明,即使在不可能进行再分配的情况下,仅仅根据支付意愿来分配商品仍然不是功利主义的最优选择。最后,我们强调如何以最低出价和竞标补贴的拍卖方式实施我们的机制。

Mathematics of the Armington, Krugman and Melitz Models with Multiple Sectors and Heterogeneous Regions, With Detailed Derivations 阿明顿,克鲁格曼和梅利茨模型与多部门和异质区域的数学,与详细的推导
Pub Date : 2020-08-19 DOI: 10.2139/ssrn.3517390

We provide detailed textbook style mathematical derivations of an extended version of the heterogenous firms model of Melitz (2003), as well as the Armington (1969) and Krugman (1980) models. Our model of heterogeneous firms extends the model of Melitz (2003) by allowing multiple sectors, intermediates, heterogeneous regions based on data, labor-leisure choice, initial heterogeneous tariffs as well as iceberg trade costs, multiple factors of production and the possibility of sector-specific inputs. Balistreri and Tarr (2019) apply these models to data where they assess the relative welfare impacts of trade cost reductions. We hope this will be a clear roadmap for understanding and constructing modern multi-sector, multi-region international trade models that must be fitted to data.
我们提供了Melitz(2003)异质企业模型的扩展版本,以及Armington(1969)和Krugman(1980)模型的详细教科书式数学推导。我们的异质企业模型扩展了Melitz(2003)的模型,允许基于数据的多部门、中间体、异质区域、劳动闲暇选择、初始异质关税以及冰山贸易成本、多生产要素和部门特定投入的可能性。Balistreri和Tarr(2019)将这些模型应用于评估贸易成本降低对相对福利影响的数据。我们希望这将成为理解和构建现代多部门、多地区国际贸易模型的清晰路线图,这些模型必须与数据相适应。

Perceived Equitability and Labor Participation 感知公平和劳动参与
Pub Date : 2020-08-15 DOI: 10.2139/ssrn.3674417
Elmira Ashtari, A. Mazyaki
While the “relative Gini coefficient” is one of the common criteria for measuring inequality, people’s perception of inequality seems to go beyond this criterion. Hence, self-report of subjective well-being (SWB) is becoming the focus of studies in public policies to improve social welfare. Since such statistics are not currently available in Iran, we are seeking for the best possible measure that can reflect subjective inequality of individuals with existing data. Investigating this issue besides people’s reaction to feeling deprived sheds light on an important attitude of the society, and is useful in policy design. This is because as a result of feeling inequitable, some people may stop their economic participation, while others try to be constructive and increase their economic activity. In this regard, we first introduce a criterion for the representation of subjective inequality at the individual level, and investigate the results of measuring subjective inequality for nominal and real values, urban and rural areas, as well as by the gender groups. We then address the effect of this perceived inequality on the economic participation of individuals. Accordingly, we distinguish the effects of subjective inequality on economic participation by age groups in the range of 15 to 65 years. The results indicate that the subjective inequality among women is greater than men, and is increasing over the years under study. It also appears that the increase in perceived equitability has had its most destructive effect on the middle class, deciles 5-8, while lower deciles react constructively in subjective deprivation.
虽然“相对基尼系数”是衡量不平等的常用标准之一,但人们对不平等的感知似乎超出了这一标准。因此,主观幸福感自我报告正成为公共政策研究的热点,以提高社会福利水平。由于伊朗目前没有这样的统计数据,我们正在寻求能够用现有数据反映个人主观不平等的最佳措施。除了人们对被剥夺感的反应之外,调查这个问题可以揭示社会的一个重要态度,对政策设计很有帮助。这是因为由于感觉不公平,一些人可能会停止他们的经济参与,而另一些人则试图发挥建设性作用,增加他们的经济活动。在这方面,我们首先介绍了个人层面主观不平等表现的标准,并调查了名义和实际价值、城市和农村地区以及性别群体衡量主观不平等的结果。然后,我们讨论了这种感知到的不平等对个人经济参与的影响。因此,我们区分了主观不平等对15至65岁年龄组经济参与的影响。结果表明,女性的主观不平等程度大于男性,并且在研究期间呈增加趋势。此外,似乎感知公平的增加对中产阶级(5-8分位数)的破坏性影响最大,而较低的十分位数对主观剥夺的反应是建设性的。

The Cross-Sectional Impact of Income Inequality on Life Quality Indicators 收入不平等对生活质量指标的横截面影响
Pub Date : 2020-08-12 DOI: 10.20474/jabs-6.4.5
X. Xi
This paper studies the consequences that income inequality exerts on the life quality in a subset of selected countries. Specifically, I examine the impact of (log) GDP per capita and the Gini coefficient of income inequality on a set of life quality indicators. First, both life expectancy and infant mortality are improved when there is less inequality and the country is wealthier. Second, the effect on crime statistics is more mixed. While theft increases with GDP per capita, the inequality does not seem to play a role; conversely, homicide increases in inequality but remains unaffected by GDP. Plausible explanations for these empirical observations are offered throughout the paper.
本文研究了收入不平等对选定国家子集的生活质量的影响。具体来说,我研究了(log)人均GDP和收入不平等的基尼系数对一组生活质量指标的影响。首先,当不平等减少、国家富裕时,预期寿命和婴儿死亡率都会提高。其次,对犯罪统计的影响更为复杂。虽然盗窃行为随着人均GDP的增加而增加,但不平等似乎并没有发挥作用;相反,谋杀加剧了不平等,但不受GDP的影响。对这些实证观察的合理解释贯穿全文。

The Interaction Effect of Gender and Ethnicity in Loan Approval: A Bayesian Estimation with Data from a Laboratory Field Experiment 性别和种族在贷款审批中的交互作用:基于实验室实地试验数据的贝叶斯估计

Microfinance targets women and uses loan provision as a tool for empowerment, which translates into better household nutrition, improved education, and a scale down of domestic violence. However, ethnic discrimination in microfinance may exist in countries with a segregated indigenous population. We assessed this possibility with a field experiment in Bolivia. The controlled laboratory experiment evaluated whether credit officers rejected microloan applications based on the interaction effect of ethnicity and gender of potential borrowers. Point estimates of a Bayesian mixed‐effects logistic regression, estimated with the experimental data, indicate that nonindigenous women have double the chance of loan approval, but indigenous women have only 1.5 times the chance of loan approval when compared with men. While the findings about gender are limited, the evidence for the interaction of gender and ethnicity is more robust and suggests the existence of positive taste‐based discrimination favorable for nonethnic women in Bolivia. We conclude that the affirmative actions towards women promoted by development agencies and microfinance institutions must not overlook ethnicity as an important factor for financial policies of sustainable development. In practice, these policies should be aimed at identifying and reducing both social desirability bias and the structural barriers to financial inclusion that indigenous women may face when trying to obtain access to a loan.
小额信贷以妇女为目标,将提供贷款作为赋权的工具,从而改善家庭营养,改善教育,减少家庭暴力。然而,在土著人口隔离的国家,小额信贷可能存在种族歧视。我们在玻利维亚进行了实地试验,评估了这种可能性。对照实验室实验评估了信贷人员是否基于潜在借款人的种族和性别的相互作用而拒绝小额贷款申请。用实验数据估计的贝叶斯混合效应逻辑回归的点估计表明,非土著妇女获得贷款批准的机会是男性的两倍,但土著妇女获得贷款批准的机会只有男性的1.5倍。虽然关于性别的研究结果有限,但性别和种族相互作用的证据更为有力,表明玻利维亚存在有利于非种族妇女的基于积极品味的歧视。我们的结论是,发展机构和小额信贷机构促进的对妇女的肯定行动绝不能忽视种族作为可持续发展财政政策的一个重要因素。在实践中,这些政策的目的应是查明和减少土著妇女在试图获得贷款时可能面临的社会可取性偏见和金融包容性的结构性障碍。

The Failure to Grapple with Racial Capitalism in European Constitutionalism 欧洲立宪主义中种族资本主义的失败
Pub Date : 2020-07-09 DOI: 10.2139/ssrn.3647178
Jeffrey Miller, F. Nicola
Since the 1980s prominent scholars of European legal integration have used the example of U.S. constitutionalism to promote a federal vision for the European Community. These scholars, drawing lessons from developments across the Atlantic, concluded that the U.S. Supreme Court had played a key role in fostering national integration and market liberalization. They foresaw the possibility for the European Court of Justice (ECJ) to be a catalyst for a similar federal and constitutional outcome in Europe. The present contribution argues that the scholars who constructed today’s dominant European constitutional paradigm underemphasized key aspects of the U.S. constitutional experience, including judgments that favored states’ rights doctrines that buttressed the social plagues of slavery and laissez faire policies that reinforced economic inequality. This selective reception of the U.S. experience, bracketing racial subordination and neoliberal policies under the rubric of states’ rights, propelled European constitutionalism into a neverland—one that claimed to draw inspiration from U.S. constitutionalism, while simultaneously dismissing as irrelevant some of its most profound socio-economic challenges. This is important, we argue, because the dominant European constitutional paradigm not only provides a distorted picture of U.S. constitutionalism, but also inhibits a deeper understanding of the European one due to its inability to grapple with racial capitalism, embedded both in its colonial past and its present ECJ antidiscrimination jurisprudence.
自20世纪80年代以来,研究欧洲法律一体化的著名学者就以美国宪政为例,推动欧洲共同体的联邦愿景。这些学者从大西洋两岸的发展中吸取教训,得出结论认为,美国最高法院在促进国家一体化和市场自由化方面发挥了关键作用。他们预见到欧洲法院(ECJ)可能成为欧洲类似联邦和宪法结果的催化剂。本论文认为,构建当今占主导地位的欧洲宪法范式的学者们低估了美国宪法经验的关键方面,包括支持各州权利原则的判决,这些原则助长了奴隶制的社会祸害,以及加剧了经济不平等的自由放任政策。这种对美国经验的选择性接受,将种族从属和新自由主义政策放在国家权利的标题下,将欧洲的宪政推向了一个梦幻之地——一个声称从美国宪政中汲取灵感的地方,同时又将其一些最深刻的社会经济挑战视为无关紧要。我们认为,这一点很重要,因为占主导地位的欧洲宪法范式不仅提供了一幅扭曲的美国宪政图景,而且由于其无法应对种族资本主义,从而抑制了对欧洲宪法的更深入理解,这既植根于其殖民历史,也植根于其当前的欧洲法院反歧视判例。

This is important, we argue, because the dominant European constitutional paradigm not only provides a distorted picture of U.S. constitutionalism, but also inhibits a deeper understanding of the European one due to its inability to grapple with racial capitalism, embedded both in its colonial past and its present ECJ antidiscrimination jurisprudence.","PeriodicalId":129815,"journal":{"name":"Microeconomics: Welfare Economics & Collective Decision-Making eJournal","volume":"108 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127064072","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}

Russian Abstract: Определение социальной эффективности и социальных технологий лежит в основе методов и моделей оценки с учетом широкого спектра объективных и субъективных факторов. Методологии оценки эффективности социальной програмы (проекта) связаны с ориентацией социальной системы на социальную защиту и социальное обслуживание населения и использованием процессного подхода и перехода к программно-целевым методам, с изложением основных проблем, механизмов социальных услуг и задач для измерения, определения основных требований для оценки эффективности социального программирования и различных этапов. Рассматривая все эти вопросы, в исследовании предлагается модель для оценки эффективности социального программирования, основанная на подходе «организационная эффективность» и охватывающая набор элементов - систему получения ресурсов, выбора целей, оценки воздействия внешней среды, выбора стратегии, следуя принципу «что если» и приоритетам в социальной деятельности, возникающим в результате динамических изменений в социальной среде.

English Abstract: Defining social efficiency and social technology is the core element of evaluation methods and models, taking into account a wide range of objective and subjective factors. The evaluation methods of social programmes (projects) efficiency are related to the social system’s orientation towards social protection and social services of the population and the use of the process approach and the transition to programme-target methods, outlining the main issues and mechanisms for social services and tasks for assessment, determining the basic requirements for efficiency evaluation of social programming and the various stages. Considering all these matters, the research offers social programming efficiency evaluation model based on “organizational efficiency” approach that covers a number of certain elements: system for resources acquisition, choice of goals, assessment of the impact on the external environment, choice of strategy, following the “what if” principle and the priorities of social activity, arising from the dynamic changes in social environment.
俄罗斯Abstract:社会效率和社会技术的定义是基于客观和主观因素的方法和模型。评价社会程序效率的方法(项目)是指社会制度注重社会保护和社会服务,采用过程方法和方案目标,阐述主要问题、社会服务机制和测量任务,确定评估社会程序效率和不同阶段的基本要求。考虑这些问题,研究提出社会基于编程方法的有效性模型来评估组织绩效奖和一组元素涵盖系统获得资源、选择目标,环境影响评估、选择战略,遵循“如果”的原则和优先事项在社会活动,产生的动态变化的社会环境。英语Abstract:定义社会技能和社会技术是进步的媒介和模型的核心。评估methods of social课程(项目)efficiency are related to The social system ' s orientation走向social protection and social services of The population and The use of The process方法and The transition to奖学金target methods, outlining The main issues and mechanisms for social services and tasks for评估determining The basic requirements for efficiency评估of social programming and The《(stage。Considering all these matters, the research offers social programming efficiency评估模型基于on " organizational efficiency方法that cover a number of《时间轴:system for resources acquisition, choice of目标评估of the impact on the对外环境choice of strategy, 42,269《what if》principle and the priorities of social - based,新的征程from the dynamic changes in social环境。
