Abstract A seller is selling multiple objects to a set of agents, who can buy at most one object. Each agent's preference over (object, payment) pairs need not be quasilinear. The seller considers the following desiderata for her mechanism, which she terms desirable: (1) strategy-proofness, (2) ex-post individual rationality, (3) equal treatment of equals, (4) no wastage (every object is allocated to some agent). The minimum Walrasian equilibrium price (MWEP) mechanism is desirable. We show that at each preference profile, the MWEP mechanism generates more revenue for the seller than any desirable mechanism satisfying no subsidy. Our result works for the quasilinear domain, where the MWEP mechanism is the VCG mechanism, and for various non-quasilinear domains, some of which incorporate positive income effect of agents. We can relax no subsidy to no bankruptcy in our result for certain domains with positive income effect.
一个卖家将多个物品出售给一组代理,这些代理最多只能购买一个物品。每个代理对(对象,支付)对的偏好不需要是拟线性的。卖方认为她的机制有以下几个理想,她称之为理想:(1)策略抗扰性,(2)事后个人理性,(3)平等对待,(4)不浪费(每个对象都分配给某个代理)。最小瓦尔拉斯均衡价格(MWEP)机制是可取的。我们表明,在每一种偏好情况下,MWEP机制比任何不满足补贴的理想机制为卖方带来更多的收入。我们的结果适用于拟线性领域,其中MWEP机制是VCG机制,以及各种非拟线性领域,其中一些领域包含代理商的正收益效应。对于某些具有正收益效应的领域,我们可以在我们的结果中放宽不补贴到不破产。

Is Inequality of Opportunity Robust to the Measurement Approach? 机会不平等对测量方法是稳健的吗?
Pub Date : 2020-01-06 DOI: 10.1111/ROIW.12448
Xavier Ramos, Dirk Van de gaer
Recent literature has suggested many ways of measuring equality of opportunity. We analyze in a systematic manner the various approaches put forth in the literature to show whether and to what extent different choices matter empirically. We use EU-SILC data for most European countries for 2005 and 2011. The choice between ex-ante and ex-post approaches is crucial and has a substantial influence on inequality of opportunity country orderings. Growth regressions also illustrate the relevance of conceptual choices. We only find significant negative effects for some direct parametric ex-ante measures.
最近的文献提出了许多衡量机会平等的方法。我们以系统的方式分析了文献中提出的各种方法,以显示不同的选择在经验上是否重要以及在多大程度上重要。我们使用EU-SILC 2005年和2011年大多数欧洲国家的数据。事前和事后方法之间的选择是至关重要的,对国家排序的机会不平等有重大影响。增长回归也说明了概念选择的相关性。我们只发现一些直接参数事前度量的显著负影响。

Corporate Profitability and the Global Persistence of Corruption 企业盈利能力与全球腐败的持续存在
Pub Date : 2020-01-01 DOI: 10.2139/ssrn.3637645
Stephen P. Ferris, J. Hanousek, J. Tresl
We examine the persistence of corporate corruption for a sample of privately-held firms from 12 Central and Eastern European countries over the period 2001 to 2015. Creating a proxy for corporate corruption based on a firm’s internal inefficiency, we find that corruption enhances a firm’s profitability. A channel analysis further reveals that inflating staff costs is the most common approach by which firms divert funds to finance corruption. We conclude that corruption persists because of its ability to improve a firm’s return on assets, which we refer to as the Corporate Advantage Hypothesis.
我们以2001年至2015年12个中欧和东欧国家的私营企业为样本,研究了企业腐败的持久性。在企业内部效率低下的基础上建立企业腐败的代理,我们发现腐败提高了企业的盈利能力。一项渠道分析进一步表明,夸大员工成本是企业转移资金以资助腐败的最常见方法。我们的结论是,腐败之所以持续存在,是因为它有能力提高企业的资产回报率,我们称之为企业优势假说。

The Evolution of Inequality of Opportunity in Germany: A Machine Learning Approach 德国机会不平等的演变:机器学习方法
Pub Date : 2020-01-01 DOI: 10.2139/ssrn.3570385
P. Brunori, Guido Neidhöfer
We show that measures of inequality of opportunity (IOP) fully consistent with Roemer (1998)'s IOP theory can be straightforwardly estimated by adopting a machine learning approach, and apply our novel method to analyse the development of IOP in Germany during the last three decades. Hereby, we take advantage of information contained in 25 waves of the Socio-Economic Panel. Our analysis shows that in Germany IOP declined immediately after reunification, increased in the first decade of the century, and slightly declined again after 2010. Over the entire period, at the top of the distribution we always find individuals that resided in West-Germany before the fall of the Berlin Wall, whose fathers had a high occupational position, and whose mothers had a high educational degree. East-German residents in 1989, with low educated parents, persistently qualify at the bottom.
我们表明,与Roemer(1998)的IOP理论完全一致的机会不平等(IOP)的度量可以通过采用机器学习方法直接估计,并应用我们的新方法来分析德国在过去三十年中IOP的发展。在此,我们利用社会经济小组25次会议所载的资料。我们的分析表明,德国的IOP在统一后立即下降,在本世纪的第一个十年上升,并在2010年之后再次略有下降。在整个时期,在分布的顶端,我们总是发现在柏林墙倒塌之前居住在西德的人,他们的父亲有很高的职业地位,他们的母亲有很高的教育程度。1989年的东德居民,由于父母受教育程度较低,一直处于社会底层。

Shocks, Frictions, and Inequality in US Business Cycles 美国商业周期中的冲击、摩擦和不平等
Pub Date : 2020-01-01 DOI: 10.2139/ssrn.3536730
Christian Bayer, Benjamin Born, R. Luetticke
How much does inequality matter for the business cycle and vice versa? Using a Bayesian likelihood approach, we estimate a heterogeneous-agent New-Keynesian (HANK) model with incomplete markets and portfolio choice between liquid and illiquid assets. The model enlarges the set of shocks and frictions in Smets and Wouters (2007) by allowing for shocks to income risk and taxes. We find that adding data on inequality does not materially change the estimated shocks and frictions driving the US business cycle. The estimated shocks, however, have significantly contributed to the evolution of US wealth and income inequality. The systematic components of monetary and fiscal policy are important for inequality as well.
不平等对商业周期有多大影响,反之亦然?使用贝叶斯似然方法,我们估计了一个具有不完全市场和流动性和非流动性资产之间的投资组合选择的异质代理新凯恩斯(HANK)模型。该模型通过考虑收入风险和税收的冲击,扩大了Smets和Wouters(2007)的冲击和摩擦集。我们发现,增加关于不平等的数据并不能实质性地改变对推动美国商业周期的冲击和摩擦的估计。然而,估计的冲击在很大程度上加剧了美国财富和收入不平等的演变。货币和财政政策的系统性组成部分对不平等也很重要。

Rationalizable Incentives: Interim Implementation of Sets in Rationalizable Strategies 合理化激励:合理化策略中集合的临时实现
Pub Date : 2020-01-01 DOI: 10.2139/ssrn.3540535
Takashi Kunimoto, R. Serrano
This paper investigates rationalizable implementation of social choice sets (SCSs) in incomplete information environments. We identify rationalizable incentive compatibility (RIC) as its key condition, argue by means of example that RIC is strictly weaker than the standard Bayesian incentive compatibility (BIC), and show that RIC reduces to BIC when we only consider single-valued SCSs (i.e., social choice functions or SCFs). We next identify additional necessary conditions and, essentially closing the gap be-tween necessity and sufficiency, obtain a sufficiency result for rationalizable implementation in general environments. We also characterize a well-studied class of economic environments in which RIC is essentially the only condition needed for rationalizable implementation. Considering SCFs, we show that interim rationalizable monotonicity, found in the literature, is not necessary for rationalizable implementation, as had been previously claimed.
本文研究了不完全信息环境下社会选择集的合理化实现。本文确定了合理激励兼容性(ricable incentive compatibility, RIC)作为其关键条件,并通过实例论证了ricable严格弱于标准贝叶斯激励兼容性(BIC),并表明当我们只考虑单值的社会选择函数(即社会选择函数或SCFs)时,ricable降为BIC。接下来,我们确定额外的必要条件,并从本质上缩小必要性和充分性之间的差距,从而获得在一般环境中合理实施的充分性结果。我们还描述了一类经过充分研究的经济环境,其中RIC本质上是合理实施所需的唯一条件。考虑到scf,我们表明,在文献中发现的临时合理化单调性对于合理化实现并不必要,正如之前所声称的那样。

We synthesize and review retrospective analyses of federal air quality regulations to examine the contributions of the Clean Air Act (CAA) to the vast air quality improvements seen since 1970. Geographic heterogeneity in stringency affects emissions, public health, compliance costs, and employment. Cap-and-trade has delivered greater emission reductions at lower cost than conventional mandates, yet has fallen short of textbook ideals. Market power also influenced the CAA’s benefits and costs. New benefit categories have been identified ex post, but specific technology requirements have not yet been rigorously evaluated. Comparisons of aggregate benefits and costs of the CAA are beyond present capabilities. (JEL D61, K32, Q51, Q53, Q58)

Today’s customers are ethically conscious and prefer those products that are ethically produced without using child labor and harm to animals and nature.This study shows various factors that affect ethical consumption and happiness. We proposed a model explaining effect of ethical purchase on happiness and onwards to repurchase intention. For this purpose this research adopted (Hwang & Kim, 2016) model of factors affecting happiness and repurchase intention and added variables such as ethical consumption, altruism and ethical obligation from (Oh & Yoon, 2014). Using a questionnaire-based survey, the data were collected from 212 respondents to analyze their attitude towards ethical consumption and happiness. To analyze data and test the hypothesis, Structured Equation modeling, PLS algorithm and bootstapping were used. The results showed that guilt positively affects empathy. However, empathy does not affect ethical consumption. Narcissism positively affects self-actualization. While, Self-actualization negatively affect ethical consumption. Ethical obligation also inversely affect ethical consumption however the relationship seems to be insignificant. Surprisingly, Altruism and ethical consumption also seems to have a negative connection. Moreover, ethical consumers didn’t draw happiness out of their purchase, however, happiness positively affected repurchase intention. The results of this study demonstrate the strong associations of the paths from happiness to repurchase intention, happiness to self-actualization, repurchase intention to happiness and self-actualization to happiness.
今天的顾客有道德意识,更喜欢那些没有使用童工和伤害动物和自然的道德生产的产品。本研究显示了影响道德消费和幸福感的各种因素。我们提出了一个模型来解释道德购买对幸福感和再购买意愿的影响。为此,本研究采用了(Hwang & Kim, 2016)影响幸福感和回购意愿的因素模型,并增加了(Oh & Yoon, 2014)中的道德消费、利他主义和道德义务等变量。采用问卷调查的方式,从212名受访者中收集数据,分析他们对道德消费和幸福的态度。为了分析数据和检验假设,使用了结构化方程建模、PLS算法和自举。结果表明,内疚对同理心有积极影响。然而,同理心并不影响道德消费。自恋对自我实现有积极影响。而自我实现对伦理消费有负向影响。道德义务对道德消费也有负相关影响,但这种关系似乎不显著。令人惊讶的是,利他主义和道德消费似乎也有负相关。此外,道德消费者并未从购买中获得快乐,但快乐正向影响再购买意愿。本研究结果显示,从快乐到再购买意愿、快乐到自我实现、再购买意愿到快乐、自我实现到快乐的路径具有较强的关联性。

Assortative Mating and Earnings Inequality in France 法国的分类交配和收入不平等
Pub Date : 2019-12-15 DOI: 10.1111/ROIW.12450
N. Frémeaux, A. Lefranc
This paper analyzes economic assortative mating and its contribution to inequality in France. We first provide descriptive evidence on the statistical association in several socio-economic attributes of partners among French couples (annual earnings, potential earnings, education, occupation). Second, we assess the contribution of assortative mating to earnings inequality between couples. Contrary to previous estimates, we account for possible biases in the estimation of assortative mating arising from sample-selection into the labor force. We also provide a new method for assessing the contribution of assortative mating to inequality in couple's potential earnings. Our results indicate a strong degree of assortative mating in France. The correlation coefficient for education is above 0.6. The correlation in earnings is lower but sizable: around 0.17 for annual earnings, when including zeroes; around 0.35 for full-time equivalent earnings and up to 0.49 when using multi-year average earnings. We show that assortative mating tends to increase inequality among couples, compared to random mating. For annual earnings, the effect is non-negligible and accounts for 3 to 9% of measured inequality. The effect of assortative mating on household potential earnings is much larger and amounts to 10 to 20% for observed inequality.
本文分析了法国的经济分类交配及其对不平等的贡献。我们首先提供描述性证据,证明法国夫妇中伴侣的几个社会经济属性(年收入、潜在收入、教育程度、职业)的统计关联。其次,我们评估了选择性交配对夫妻之间收入不平等的贡献。与之前的估计相反,我们考虑了由于劳动力样本选择而产生的分类交配估计中的可能偏差。我们还提供了一种新的方法来评估选择性交配对夫妻潜在收入不平等的贡献。我们的研究结果表明,在法国,选择性交配的程度很高。教育相关系数在0.6以上。收益的相关性较低,但相当可观:包括零在内,年收入的相关性约为0.17;全职等效收入约为0.35,使用多年平均收入时高达0.49。我们表明,与随机交配相比,选择性交配往往会增加夫妻之间的不平等。就年收入而言,这种影响是不可忽视的,占衡量不平等的3%至9%。分类交配对家庭潜在收入的影响要大得多,对观察到的不平等的影响达到10%到20%。

The effect of assortative mating on household potential earnings is much larger and amounts to 10 to 20% for observed inequality.","PeriodicalId":129815,"journal":{"name":"Microeconomics: Welfare Economics & Collective Decision-Making eJournal","volume":"376 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131544996","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}

Taking Down the Wall: Transition and Inequality 推倒高墙:转型与不平等

Serhan Cevik, Carolina Correa-Caro
In this article, we investigate the main determinants of income inequality in the transition countries of Central and Eastern Europe and the Commonwealth of Independent States during the period 1990–2018. To this end, we address a major methodological challenge that lies at the core of the cross‐country literature on income inequality: the potential endogeneity of income per capita, which is largely ignored by most empirical studies. We adopt a two‐pronged empirical strategy by (1) using trading partners’ weighted average real GDP as an instrumental variable and (2) estimating the model via the two‐stage least squares approach for static models and the generalized method of moments estimator for dynamic models. Our empirical findings are consistent with the Kuznets curve that illustrates a nonlinear relationship between income inequality and the level of economic development. We also find that the redistributive impact of fiscal policy is statistically insignificant and taxation and government spending appear to have the opposing effects on income inequality in transition economies over the sample period.
在本文中,我们研究了1990年至2018年期间中欧、东欧和独联体转型国家收入不平等的主要决定因素。为此,我们解决了一个主要的方法论挑战,这是关于收入不平等的跨国文献的核心:人均收入的潜在内生性,这在很大程度上被大多数实证研究所忽视。我们采用了双管齐下的经验策略:(1)使用贸易伙伴的加权平均实际GDP作为工具变量;(2)通过静态模型的两阶段最小二乘法和动态模型的广义矩估计方法来估计模型。我们的实证研究结果与库兹涅茨曲线一致,该曲线说明了收入不平等与经济发展水平之间的非线性关系。我们还发现,财政政策的再分配影响在统计上是微不足道的,税收和政府支出似乎在样本期内对转型经济体的收入不平等产生相反的影响。
