Sectoral Real Exchange Rates and Manufacturing Exports: A Case Study of Latin America 部门实际汇率与制造业出口:以拉丁美洲为例

Standard theory considers the real exchange rate (RER) as export determinant. A common limitation of cross-country evidence is the use of effective (REER) or bilateral (BRER) RER indices, both of which have the same values across sectors. The novel contributions of this paper are a variety of goods trade model, to exploit cross-sector variations by constructing a unique sectoral bilateral RER index (SBRER) for 12 Latin American countries, 21 sectors and 38 trade partners, and to estimate the effect of RER movements on manufacturing exports during 2001-2018. The results show that the SBRER is a significant determinant of aggregate manufacturing exports, whereas the REER and BRER appear not to be significant. Sectoral export elasticities moreover indicate that in Latin America mainly low-technology sectors are affected by RER movements. Overall these findings indicate that sectoral differences matter and provide new evidence on the effect of RER movements on Latin American exports.
标准理论认为实际汇率(RER)是出口的决定因素。跨国证据的一个常见限制是使用有效(REER)或双边(BRER) RER指数,这两种指数在各部门具有相同的值。本文的新贡献是建立了多种商品贸易模型,通过构建12个拉丁美洲国家、21个部门和38个贸易伙伴的独特部门双边RER指数(SBRER)来利用跨部门差异,并估计2001-2018年RER变动对制造业出口的影响。结果表明,sbrr是制造业出口总量的重要决定因素,而REER和brr似乎不显著。部门出口弹性还表明,在拉丁美洲,主要是低技术部门受到RER变动的影响。总的来说,这些发现表明,部门差异很重要,并为RER变动对拉丁美洲出口的影响提供了新的证据。

This paper investigates the pathways through which immigrant communities (social networks) influence individual naturalization. Specifically, we examine the impact that a fraction of naturalized co-ethnics, residing in the same block as a new immigrant in New York City in 1930, have on the probability of said immigrant becoming a U.S. citizen in 1940. Our results indicate that the concentration of naturalized co-ethnics residing in the block positively predicts individual naturalization and that this relationship operates through one main channel: information dissemination. Indeed, immigrants who live among naturalized co-ethnics are more likely to naturalize because they have greater access to critical information about the benefits and procedures of naturalization.
本文探讨了移民社区(社会网络)影响个人入籍的途径。具体来说,我们研究了1930年与纽约市新移民居住在同一街区的一部分归化的同种族对上述移民在1940年成为美国公民的可能性的影响。我们的研究结果表明,居住在街区的归化同种族的集中积极地预测了个人的归化,这种关系通过一个主要渠道起作用:信息传播。事实上,生活在已入籍的同种族中的移民更有可能入籍,因为他们更容易获得有关入籍的好处和程序的关键信息。

Greater Female Employment Participation as a Catalyst to Reducing Income Inequality in Developing Countries – The Case of Latin American and Sub-Saharan African Countries 提高女性就业参与度是减少发展中国家收入不平等的催化剂——以拉丁美洲和撒哈拉以南非洲国家为例
Pub Date : 2020-12-03 DOI: 10.2139/ssrn.3741992
S. Sobhee
This paper unravels the linkage between income inequality and women’s participation in the labor force within a group of developing countries drawn from Latin America and sub-Saharan Africa. It adds to the existing body of literature by providing additional empirical evidence and pertinent situations to a group of countries in which current empiricism on the subject is to a large extent scanty. The choice of these countries has been done basically on grounds that they are subjected to very high income inequality trends and relentless policies encompassing gender biases. The traits are common to both sets of countries. Our regression results, based on 45 countries, clearly unfold that greater female participation in these countries tend to reduce income inequality. The major policy implication that emanates from this research is that governments in these countries should emphasize on empowering women to achieve greater gender equity in employment, lower income inequality and higher welfare for all.
本文在拉丁美洲和撒哈拉以南非洲的一组发展中国家中揭示了收入不平等与妇女参与劳动力之间的联系。它通过向一组国家提供额外的经验证据和相关情况来补充现有的文献,这些国家目前在这个问题上的经验主义在很大程度上是贫乏的。选择这些国家的基本理由是,它们受到非常严重的收入不平等趋势和包含性别偏见的无情政策的影响。这两类国家都有共同的特点。我们基于45个国家的回归结果清楚地表明,在这些国家,更多的女性参与往往会减少收入不平等。这项研究产生的主要政策含义是,这些国家的政府应强调赋予妇女权力,以便在就业方面实现更大的性别平等,减少收入不平等,提高所有人的福利。

What Makes a Tax Evader? 什么是逃税者?
Pub Date : 2020-12-01 DOI: 10.2139/ssrn.3750462
M. Bérgolo, Martin Leites, Ricardo Perez-Truglia, Matias Strehl
Why do some individuals choose to evade taxes while others do not? One popular view is that some individuals cheat on their taxes because they are more dishonest, selfish, or perceive different social norms. There is, however, little direct evidence on this matter. In collaboration with the national tax agency in Uruguay, we address this question using a combination of surveys and administrative records. Leveraging a unique institutional setting, we measure individual-level evasion choices. We document significant variation in evasion decisions across individuals. For a subsample of 6,078 taxpayers, we use survey questions and incentivized laboratory games to measure traits such as honesty, selfishness, and perceived social norms. We find that these individual traits have some power to predict who evades taxes, but other factors, such as the environment, play a much bigger role.
为什么有些人选择逃税,而另一些人却没有?一种流行的观点是,一些人逃税是因为他们更不诚实、自私,或者认为社会规范不同。然而,关于这个问题的直接证据很少。我们与乌拉圭国家税务机构合作,结合调查和行政记录来解决这个问题。利用独特的制度设置,我们衡量个人层面的逃避选择。我们记录了个体之间逃避决策的显著差异。对于6,078名纳税人的子样本,我们使用调查问题和激励实验室游戏来衡量诚实,自私和感知社会规范等特征。我们发现,这些个人特征对预测谁会逃税有一定的作用,但环境等其他因素的作用要大得多。

Petrobras of Brazil the Impact on the Pre-Salt Oil Wells 巴西石油公司:对盐下油井的影响
Pub Date : 2020-10-13 DOI: 10.2139/ssrn.3711070
Ty Branch
First, the purpose of this paper is to investigate and examine a case study on Petrobras Brazil’s largest Latin-American state-owned oil company, its cost of capital, corruption, and the privatization of its growing pre-salt oil reserves. Next, the paper will be a qualitative research into the corruption scandal by Brazil’s former President Dilma Rousseff and the serious allegations. The government believes that she was part of the corruption not a part of the solution during her position as Chairman of Petrobras, which she has destroyed the brand name, as well as, drove the company into 130 billion dollar debt as of 2016. Hence, since the Petrobras inception in 1953 the state-own oil company now has 33% of the shares and 55% of the voting capital, which sends signals to the opposition they have the controlling rights to the company’s assets, as well as, the liabilities (Eiteman, Stonehill and Moffett, 2013).
首先,本文的目的是调查和研究巴西最大的拉丁美洲国有石油公司巴西国家石油公司的案例研究,其资本成本,腐败以及其不断增长的盐下石油储量的私有化。接下来,本文将对巴西前总统迪尔玛·罗塞夫的腐败丑闻及其严重指控进行定性研究。巴西政府认为,在她担任巴西国家石油公司董事长期间,她是腐败的一部分,而不是解决方案的一部分,她破坏了该公司的品牌,并使该公司截至2016年背负了1300亿美元的债务。因此,自1953年巴西国家石油公司成立以来,这家国有石油公司现在拥有33%的股份和55%的有表决权的资本,这向反对派发出了信号,他们拥有公司资产的控制权,以及负债(Eiteman, Stonehill和Moffett, 2013)。

Spanish Abstract: Este documento propone una reforma tributaria comprensiva tendiente a: i) asegurar la sostenibilidad de la relación Deuda Gobierno Central/PIB de tal manera que no se desborde el umbral del 70%, sabiéndose que esta ha subido del 35% al 52% en pre-pandemia;ii) mejorar la formalidad laboral de Colombia a través de desmontar cerca de 17 puntos de un total de 51 que hoy representan los sobre costos no-salariales que enfrentan las firmas operando desde Colombia;y iii) allegar recursos de solidaridad en pos-pandemia para los estratos bajos y ancianos indigentes.El esfuerzo tributario adicional requerido para alcanzar tales objetivos asciende a cerca de 5% del PIB, de los cuales se tienen fuentes relativamente bien identificadas por cerca de 3.7% del PIB hacia el mediano plazo. La profundización del IVA a la tasa del 19% aportaría cerca de 2% del PIB;tasas más progresivas en los ingresos de la clase media-alta (incluyendo ajustes al imporiqueza) aportarían 0.5% del PIB;y la reversión en algunos alivios dados a la firmas (bajo Ley 2010 del 2019) allegarían el restante 1.2% del PIB. Tal vez la mejor forma de divulgar los objetivos de esta reforma es visualizándola como un paquete fiscal que, en últimas, lograría sostenibilidad fiscal, mejoras en la calidad del mercado laboral y mayor equidad en el frente del gasto público.English Abstract: This document proposes a comprehensive tax-reform for Colombia aiming at: i) providing sustainability for the ratio of Central Government Gross Debt/GDP below the threshold of 70%, knowing that it has been raising from 35% up to 52% during 2012-2019;ii) substituting by budget allocations about 17 percentage points out of 51 of non-wage costs on behalf of the firms;and iii) create fiscal room to increase support for low strata families, particularly affected by the pandemic of Covid-19 which erupted over 2020-2021.We conclude that achieving such fiscal goals will require close to 5% of GDP of additional tax collections of which we here identified nearly 3.7% of GPD over the period 2021-2022. By extending from 45% to 90% of invoicing-items the application of the current general VAT-rate of 19%, about 2% of GPD could be raised;the use of more progressive income-tax rates and lowering the level of application of the current wealth-tax on households would increase tax collections in about 0.5% of GDP;and, finally, the reversion of some tax-exemptions recently granted to firms (under Law 2010 of 2019) could increase tax-revenue by 1.2% of GDP.Perhaps the best form to impulse this tax-reform is to envision it as an instrument to improve not only the debt sustainability of Colombia, but as an efficient instrument to improve income equality and to provide better formal opportunities for a labor market facing open unemployment at double-digit rates.
本文提出了一项全面的税收改革,旨在:㈠确保可持续性的中央政府债务/ gdp比率的方式而不是堆积门槛70%,这已经从35%增至52% pre-pandemia;㈡改善哥伦比亚劳动形式通过拆除近17总共51点,今天面临的关于no-salariales成本,占在哥伦比亚;㈢提供签名声援pos-pandemia资源低收入阶层和老人赤贫。为了实现这些目标,需要额外的税收努力约占gdp的5%,而在中期,这些努力的来源相对明确,约占gdp的3.7%。深化增值税按19%的接近gdp的2%;更累进收费收入阶级(包括设置imporiqueza)将gdp的0.5%;一些逆转和骰子签名(2010年法律下的其余2019)可以产生gdp的1.2%。也许宣传这项改革目标的最佳方式是将其视为一项财政方案,最终将实现财政可持续性、劳动力市场质量的改善和公共支出方面的更大公平性。英文摘要:本文件提出哥伦比亚全面税制改革,目标如下:㈠提供sustainability for the of Gross中央政府债务/ GDP比率以下70%降低门槛,knowing that it has been from 35% up to raising 52% during 2012-2019;㈡substituting by budget的about 17百分比points out of non-wage costs on behalf of the第51;和㈢create财政房间以增加support for low strata家人,特别是影响by the virus of Covid-19 which erupted over -。我们的结论是,要实现这些财政目标,额外税收征收将需要接近GDP的5%,我们在此确定,在2021-2022年期间,这将接近GDP的3.7%。By帮助从45%到90% of invoicing-items the application of the current一般性VAT-rate 19%, about 2% of GPD还将种族主义问题;the use of more progressive income-tax房费and: the level of application of the current wealth-tax on the将增加税collections in about占国内生产总值的0.5%;最后,and the reversion of some tax-exemptions惧的to第2010 cleary (Law of 2019)可增加tax-revenue By占国内生产总值的1.2%。也许推动这一税制改革的最佳方式是将其视为一种工具,不仅可以改善哥伦比亚的债务可持续性,而且可以成为一种有效的工具,可以改善收入平等,并为面临双倍公开失业的劳动力市场提供更好的正式机会。

In this paper I calculate the daily flows of COVID-19 cases under the current scenario of recommended social distance and restricted economic activity, and under a counterfactual uncontrolled scenario with no mitigation measures. Using official sources, I quantify the supply of hospital beds and ICUs to project the fatality of cases under both scenarios. I estimate that social distance will reduce the number of COVID-19 cases in 65%. The benefits of mitigation measures amount to a reduction of over 119,000 direct fatalities and about 121,000 deaths due to healthcare system overflow. The benefits of these measures are monetized as 697 billion USD. I estimate that the net cost of mitigation in terms of output gap over a 60-months recovery period represents 29% of 2019 Mexico's GDP. This cost would be reduced if a faster recovery occurs or if the government stimulates the economy enough to reduce output gap between the mitigation scenario and the uncontrolled scenario, making a case for an active role of fiscal policies.
在本文中,我计算了在目前建议的社会距离和限制的经济活动的情况下,以及在没有缓解措施的反事实不受控制的情况下,COVID-19病例的每日流量。利用官方资料,我量化了医院床位和重症监护病房的供应,以预测两种情况下病例的死亡率。我估计,社交距离将使COVID-19病例数减少65%。缓解措施的好处相当于减少超过119,000人的直接死亡,以及由于医疗系统溢出造成的约121,000人死亡。这些措施的收益货币化为6970亿美元。我估计,60个月恢复期的产出缺口缓解净成本占墨西哥2019年GDP的29%。如果出现更快的复苏,或者如果政府对经济的刺激力度足以缩小缓解情景与不受控制情景之间的产出差距,那么这种成本就会降低,这就说明财政政策有理由发挥积极作用。

Spanish Abstract: El presente documento muestra la aplicación de una metodología para estimar el precio cuenta de eficiencia de la divisa bajo un tipo de cambio fijo; se presenta como estudio de caso una aplicación a la economía boliviana, para el periodo 2011-2016. Un régimen del tipo de cambio fijo implica, de manera general, que el país debe tener un stock de reservas internacionales suficiente para mantenerlo en el corto plazo; en el mediano y largo plazo los ajustes en la oferta y demanda de divisas -equilibrio de la cuenta corriente- se realiza vía el tipo de cambio real -precios relativos de los bienes transables y los no transables-, incentivos (ej. subsidios a las exportaciones) y/o desincentivos (ej. aranceles), dado el tipo de cambio nominal fijo. La razón precio cuenta de la divisa bajo estas consideraciones se ve afectada no solo por las elasticidades respectivas o las ponderaciones medias de las importaciones y exportaciones e incentivos y desincentivos respectivos, sino también por la relación del Índice de tipo de cambio real de equilibrio y el Índice del tipo de cambio real vigente (ITCRE/ITCRV). Los resultados muestran que para el caso boliviano existe un des-alineamiento entre la tasa de cambio real y la tasa de cambio real de equilibrio de largo plazo y que la razón precio cuenta de la divisa para el periodo 2011-2016 con el método de ponderaciones medias de 1,19 y con el método de elasticidades de 1,19.

English Abstract: This document shows the application of a methodology to estimate the currency efficiency account price under a fixed exchange rate, an application to the Bolivian economy is presented as a case study, for the period 2011-2016. A fixed exchange rate system generally implies that the local country should maintain a sufficient level of international reserves in the short term to support the fixed rate. In the medium and long term the adjustments in currency supply and demand -current account equilibrium- are done via the real exchange rate -relative price of tradable and non-tradable goodsincentives (e.g. subsidies on exports) and disincentives (e.g. taxes), given a fixed nominal exchange rate. Under this considerations, the shadow price of the currency is affected not only by the corresponding elasticities, the average weight of imports and exports and related economic incentives but also by the relation between the real exchange rate and the active real exchange rate index. The results show that for the Bolivian economy there is a misalignment between the real exchange rate and the long term exchange rate and that the currency shadow price for the period 2011-2016 equals to 1.19 using the average weight method and 1.19 using the elasticities method.

Spanish Abstract: El gobierno federal de México ha carecido de una política laboral integral por décadas, lo que imposibilita resolver problemas ingentes en el mercado de trabajo. La fuerza de trabajo tiene una alta proporción de adultos sin habilidades fundamentales para el trabajo, y el sistema educativo aún no atiende a millones de jóvenes que ingresarán a edades de trabajar en los próximos años. La legislación laboral se basa en una visión limitada del trabajo y es incapaz de atender al trabajo “atípico”. El Estado ha sido poco eficaz en identificar oportunidades de activación, capacitación e inspección. Se plantea una visión general de la política laboral para México sobre cinco ámbitos: activación laboral, capacitación y formación para el trabajo, aseguramiento social y estabilidad laboral calidad en el trabajo e inspección laboral. También se propone una reforma de los servicios que cambiará de manera fundamental la relación del Estado con los ciudadanos.

English Abstract: Mexico's federal government has lacked a comprehensive labor policy for decades, making it impossible to solve problems of considerable importance in the labor market. The workforce has a high proportion of adults without fundamental skills for work, and the education system is not yet serving millions of young people who will enter working ages in the coming years. Labor law is based on a limited view of work and is unable to attend "atypical" work. The State has been ineffective in identifying opportunities for activation, training and inspection. An overview of labor policy for Mexico is presented in five areas: job activation, for and on-the-job training, social insurance, quality and stability of jobs, and labor inspection. A reform of services is also proposed which will fundamentally change the relationship of the State with citizens.
墨西哥联邦政府几十年来一直缺乏全面的劳工政策,这使得解决劳动力市场的巨大问题变得不可能。劳动力中没有基本工作技能的成年人比例很高,教育系统仍然无法为未来几年将进入工作年龄的数百万年轻人提供服务。劳工立法的基础是对工作的狭隘看法,无法处理“非典型”工作。国家在确定激活、培训和检查机会方面效率低下。本文从劳动激活、劳动培训和培训、社会保障和劳动稳定、劳动质量和劳动检查五个领域概述了墨西哥的劳动政策。它还提出了服务改革,这将从根本上改变国家与公民的关系。英文摘要:墨西哥联邦政府几十年来一直缺乏全面的劳工政策,无法解决劳工市场上的重大问题。劳动力中有很大比例的成年人没有基本的工作技能,教育系统还没有为几百万将在未来几年进入工作年龄的年轻人提供服务。劳动法是基于对工作的有限看法,不能等待“非典型”工作。国家在确定激活、培训和检查的机会方面效率低下。介绍了墨西哥在五个领域的劳工政策概览:就业激活、就业培训、社会保险、就业质量和稳定性以及劳工检查。还提出了服务改革,这将从根本上改变国家与公民的关系。
