Trade Liberalization and Domestic Suppliers: Evidence from Chile 贸易自由化与国内供应商:来自智利的证据
Pub Date : 2014-11-21 DOI: 10.2139/ssrn.2571301

I examine the effect of reducing export tariffs on the productivity of domestic suppliers of exporting firms. Using a panel of Chilean firms during a period of trade liberalization with the European Union, the United States, and the Republic of Korea, I show that the average reduction in the export tariff of downstream industries (1.1 percentage points) increases the productivity of intermediate input suppliers by 1.5 percent. The increase in productivity among domestic suppliers accounts for 22.5 percent of aggregate productivity gains. I find that tariff cuts induce firms to acquire new machinery and pay higher wages to skilled workers. These findings are consistent with a simple model in which lower export tariffs increase the sales of exporting firms and increase the derived demand for intermediates through input-output linkages.
我考察了降低出口关税对出口企业国内供应商生产率的影响。在智利与欧盟、美国和韩国的贸易自由化期间,我利用一组智利公司的数据表明,下游产业出口关税的平均降低(1.1个百分点)使中间投入供应商的生产率提高了1.5%。国内供应商的生产率增长占总生产率增长的22.5%。我发现关税削减促使企业购买新机器,并向熟练工人支付更高的工资。这些发现与一个简单的模型相一致,在这个模型中,较低的出口关税增加了出口公司的销售额,并通过投入产出联系增加了对中间产品的衍生需求。

Cash Transfers to the Poor and the Labor Market: An Equilibrium Analysis 向穷人的现金转移与劳动力市场:一个均衡分析
Pub Date : 2014-11-01 DOI: 10.1111/rode.12116
Tiago Cavalcanti, M. Corrêa
This paper studies the effects of cash transfers to the poor on the labor market. This is investigated in a matching model with endogenous labor market participation and job destruction. Depending on their productivity, workers might want to stay in the job, become unemployed, or leave the labor market; in addition, workers out of the labor force might decide to search for a job. Cash transfers are introduced to all agents with income below a given level. Two qualitative results are found: (i) The size of cash transfers has a negative effect on the employment rate, but an ambiguous effect on the unemployment rate; and (ii) the coverage of this welfare program has a positive effect on the employment rate, and an ambiguous effect on the unemployment rate. The numerical simulations also show that: (i) if the government target is to reduce inequality and poverty, the more efficient policy is to increase the level of benefits instead of increasing the eligibility of the program; (ii) compared with a welfare program that condition eligibility to labor market participation, the “unconditional” cash transfer program has a stronger impact on inequality and poverty, but with a reduction in labor market participation and output.
本文研究了现金转移对劳动力市场的影响。这是在一个内生劳动力市场参与和就业破坏的匹配模型中进行研究的。根据生产率的不同,工人可能想要留在工作岗位上、失业或离开劳动力市场;此外,劳动力市场之外的工人可能会决定找工作。对收入低于一定水平的所有代理人实行现金转移。两个定性结果发现:(i)现金转移的规模对就业率有负面影响,但对失业率的影响不明确;(2)该福利计划的覆盖范围对就业率有积极影响,对失业率的影响不明确。数值模拟还表明:(1)如果政府的目标是减少不平等和贫困,更有效的政策是提高福利水平,而不是增加计划的资格;(ii)与限定劳动力市场参与资格的福利计划相比,“无条件”现金转移计划对不平等和贫困的影响更大,但会减少劳动力市场参与和产出。

Markets for Scientific Attribution 科学归因市场
Pub Date : 2014-11-01 DOI: 10.2139/ssrn.2519603
J. Gans, Fiona E. Murray
Formal attribution provides a means of recognizing scientific contributions as well as allocating scientific credit. This article examines the processes by which attribution arises and its interaction with market assessments of the relative contributions of members of scientific teams and communities—a topic of interest for the organizational economics of science and in understanding scientific labor markets. We demonstrate that a pioneer or senior scientist’s decision to co-author with a follower or junior scientist depends critically on market attributions as well as the timing of the co-authoring decision. This results in multiple equilibrium outcomes each with different implications for expected quality of research projects. However, we demonstrate that the Pareto efficient organizational regime is for the follower researcher to be granted co-authorship contingent on their own performance without any earlier pre-commitment to formal attribution. We then compare this with the alternative for the pioneer of publishing their contribution and being rewarded through citations. While in some equilibria (especially where co-authoring commitments are possible) there is no advantage to interim publication, in others this can increase expected research quality. (JEL O31; O36)
正式署名提供了一种承认科学贡献以及分配科学信用的方法。本文考察了归因产生的过程及其与科学团队和社区成员相对贡献的市场评估的相互作用——这是科学组织经济学和理解科学劳动力市场感兴趣的主题。我们证明,先驱或资深科学家与追随者或初级科学家合著的决定主要取决于市场因素以及合著决定的时机。这导致了多种均衡结果,每种结果对研究项目的预期质量都有不同的含义。然而,我们证明了帕累托有效的组织机制是追随者研究者根据自己的表现被授予共同作者身份,而无需事先承诺正式归属。然后,我们将其与发表其贡献并通过引用获得奖励的先驱的替代方案进行比较。虽然在某些平衡中(特别是在可能有共同作者承诺的情况下),中期发表没有优势,但在其他平衡中,这可以提高预期的研究质量。(凝胶O31;O36)

Labor's Declining Share of Corporate Income: Impact on Income Inequality and the U.S. Job Recovery 劳动收入占企业收入的比重下降:对收入不平等和美国就业复苏的影响
Pub Date : 2014-05-21 DOI: 10.2139/SSRN.2441795
Serge L. Wind
The distribution of corporate income between profits and compensation had been stable for decades, but, beginning around 1980, U.S. firms shifted corporate income away from labor and toward capital, decreasing labor’s share. Labor’s declining share of corporate income has contributed both to widening income inequality and slowing the recovery of jobs lost during the past recession.The declining labor share exacerbated income inequality, with total compensation decreasing by roughly 2 percent annually during 1995-99, 4 percent per annum in 2001-07, and 7 percent per year in 2009-12. Rising economic inequality appears to explain about two-thirds of the failure of typical workers’ pay to keep pace with overall economic growth, as measured by productivity. The decline in labor’s share slowed the economic recovery from the last recession by constraining wage-based household consumption. The decline in the corporate investment rate translates to cumulative post-1986 underinvestment of about $4.6 trillion, which is associated with roughly 5.4 million jobs lost through 2012. These lost jobs represent 53 percent of the shortfall of 10.1 million jobs which has persisted from November 2011 through the end of 2013. The post-2005 decline in household investment rates placed increasing reliance on the corporate sector to fund investments. Several intertwined long-term economic processes and trends are associated with widening income inequality and dampening economic recovery. Globalization is associated with rising income inequality. With high-skill jobs no longer immune to replacement by machines and software, job opportunities may be on the cusp of being further diminished by advances in digital technology. Globalization and technological change have contributed to devaluation of the labor force and polarization of job opportunities. Financialization appears to be a major cause of rising income inequality. Declines in union bargaining power increased the vulnerability of domestic workers. Government underinvestment in the underlying productive capacity of the economy contributed in part to below-average GDP growth.The dearth of jobs created during 2000-2012 suggests yet another burgeoning disparity – inequality in job opportunities – between the fortunate few with entree to high-paying and high-skilled positions generated by technological advances and the large marginalized majority vying for low-income, low-skilled jobs in competition with even-lower-paid workers from emerging markets. Labor has been marginalized by the declining labor share; widening inequalities in wages, income, wealth, and job opportunities; declining corporate and government investment rates; the spreading gap between wage growth and productivity gains; below-two-percent average annual growth in real GDP during 2000-13; negative job creation beginning in 2000 and job losses in the past two recessions. The paper contains over 60 charts illustrating many of these observations.
公司收入在利润和薪酬之间的分配已经稳定了几十年,但是,从1980年左右开始,美国公司将公司收入从劳动力转移到资本,减少了劳动力的份额。劳动力在企业收入中所占份额的下降,既加剧了收入不平等,也减缓了过去经济衰退中失去的就业岗位的复苏。劳动收入占比的下降加剧了收入不平等,1995年至1999年期间,总薪酬每年下降约2%,2001年至2007年每年下降4%,2009年至2012年每年下降7%。不断加剧的经济不平等似乎可以解释三分之二的典型工人的工资未能跟上整体经济增长(以生产率衡量)的原因。劳动收入占比的下降抑制了以工资为基础的家庭消费,从而减缓了经济从上次衰退中的复苏。企业投资率的下降意味着自1986年以来累计投资不足约4.6万亿美元,到2012年,这与大约540万个就业岗位的流失有关。从2011年11月到2013年底,美国总共缺少1010万个工作岗位,而这些失业的工作占其中的53%。2005年后家庭投资率的下降,使得中国越来越依赖企业部门为投资提供资金。几个相互交织的长期经济过程和趋势与收入不平等的扩大和抑制经济复苏有关。全球化与收入不平等加剧有关。随着高技能工作不再不被机器和软件取代,工作机会可能会因数字技术的进步而进一步减少。全球化和技术变革造成了劳动力的贬值和就业机会的两极分化。金融化似乎是收入不平等加剧的一个主要原因。工会议价能力的下降增加了家政工人的脆弱性。政府对经济潜在生产能力的投资不足,在一定程度上导致GDP增长低于平均水平。2000年至2012年期间创造的就业岗位的匮乏表明,另一种日益扩大的差距——就业机会的不平等——是少数幸运者有机会获得技术进步带来的高薪高技能职位,而大多数被边缘化的人却在与来自新兴市场的工资更低的工人竞争低收入、低技能的工作。由于劳动收入占比不断下降,劳动力被边缘化;工资、收入、财富和就业机会的不平等日益扩大;企业和政府投资率不断下降;工资增长与生产率提高之间的差距不断扩大;2000- 2013年实际GDP年均增长率低于2%;2000年开始出现就业岗位负增长,过去两次经济衰退都出现了就业岗位流失。这篇论文包含了60多个图表,说明了许多这些观察结果。

Countries’ Safety and Competitiveness, and the Estimation of Current Account Misalignments 国家安全与竞争力,以及对经常账户失衡的估计
Pub Date : 2014-01-31 DOI: 10.2139/ssrn.2388590

Current account imbalances and their sustainability are among the most debated international policy issues. Through the recently designed External Balance Assessment methodology (EBA), the IMF estimates the impact of several countries’ fundamentals and policies on their current account balance, calculates misalignments in their current account position and indicates policy recommendations which, if implemented, should contribute to reducing these imbalances. In this paper, we explore some extensions to the EBA, following two courses. First, we distinguish in current account regressions between countries that are considered safe investment destinations and non-safe economies. Since this distinction is likely to acquire special relevance in periods of global turmoil, we also distinguish between periods of global stress and tranquil times. Second, we embed in EBA regressions variables that drive countries’ external competitiveness. Results show that current account dynamics may be affected by competitiveness factors and differ significantly between safe and non-safe economies, with such differences becoming particularly relevant in turbulent times. These fi ndings suggest that EBA regressions may be overlooking the influence of countries’ safety and competitiveness on external balances. Our alternative misalignment estimations show larger imbalances than those calculated with the EBA for some Asian economies and smaller imbalances for some high-surplus EU countries.
经常账户失衡及其可持续性是最受争议的国际政策问题之一。通过最近设计的外部平衡评估方法(EBA),国际货币基金组织估计了几个国家的基本面和政策对其经常账户平衡的影响,计算了其经常账户状况的失调,并提出了政策建议,这些建议如果得到实施,将有助于减少这些失衡。在本文中,我们将根据两门课程探索EBA的一些扩展。首先,我们在经常账户回归中区分被认为是安全投资目的地的国家和非安全经济体。由于这一区别在全球动荡时期可能具有特殊意义,因此我们也要区分全球紧张时期和平静时期。其次,我们在EBA回归中嵌入了驱动国家外部竞争力的变量。结果表明,经常账户动态可能受到竞争力因素的影响,并且在安全经济体和非安全经济体之间存在显著差异,这种差异在动荡时期尤为重要。这些发现表明,EBA回归可能忽略了国家安全和竞争力对外部平衡的影响。我们的替代偏差估计显示,一些亚洲经济体的失衡比用EBA计算的失衡更严重,而一些高盈余的欧盟国家的失衡更小。

Return of the Solow Paradox? It, Productivity, and Employment in U.S. Manufacturing 索洛悖论的回归?美国制造业的生产率和就业

An increasingly influential "technological-discontinuity" paradigm suggests that IT-induced technological changes are rapidly raising productivity while making workers redundant. This paper explores the evidence for this view among the IT-using U.S. manufacturing industries. There is some limited support for more rapid productivity growth in IT-intensive industries depending on the exact measures, though not since the late 1990s. Most challenging to this paradigm, and our expectations, is that output contracts in IT-intensive industries relative to the rest of manufacturing. Productivity increases, when detectable, result from the even faster declines in employment.
一个越来越有影响力的“技术中断”范式表明,it引发的技术变革正在迅速提高生产率,同时使工人变得多余。本文在使用it的美国制造业中探讨了这一观点的证据。尽管自上世纪90年代末以来,对it密集型产业生产率更快增长的支持是有限的,这取决于具体的衡量标准。对这一范式和我们的预期最具挑战性的是,相对于其他制造业,it密集型行业的产出会收缩。生产率的提高,在可以察觉的情况下,是就业下降速度更快的结果。

Buy, Keep or Sell: Economic Growth and the Market for Ideas 买,留,卖:经济增长与创意市场
Pub Date : 2013-12-01 DOI: 10.2139/ssrn.2368232

An endogenous growth model is developed where each period firms invest in researching and developing new ideas. An idea increases a firm's productivity. By how much depends on the technological propinquity between an idea and the firm's line of business. Ideas can be bought and sold on a market for patents. A firm can sell an idea that is not relevant to its business or buy one if it fails to innovate. The developed model is matched up with stylized facts about the market for patents in the United States. The analysis gauges how efficiency in the patent market affects growth.
在每个时期,企业都投资于研究和开发新思想,从而形成内生增长模型。创意可以提高公司的生产力。这在多大程度上取决于一个想法与公司业务之间的技术接近程度。创意可以在专利市场上买卖。公司可以出售与业务无关的创意,也可以在创新失败时购买创意。开发的模型与美国专利市场的风格化事实相匹配。该分析衡量了专利市场的效率如何影响增长。

This paper empirically examines the relationship between innovation, R&D (Research and Development), and productivity in Thai manufacturing using cross-sectional data from the 2007 Industrial Census of Thailand. We utilize a simplified structural model (CDM model) that describes the link between innovation output, R&D and productivity for the Thai case. Various estimation techniques are used to compare and provide evidence for empirical results. Our findings generally suggest that government aid and plant characteristics play an important role for a plant to engage in R&D and to be innovative, both in terms of process innovation and product innovation. Exporting plants, plants in the central region, and plants that are categorized as Head Branch type are more likely to engage in R&D and be innovative. The type of industry and specific technological characteristics of plants are shown to influence innovation effort and decisions to undertake R&D. On average, plant size, foreign ownership, exporting and product innovation are important drivers of productivity enhancement in Thai manufacturing.
本文利用2007年泰国工业普查的横断面数据,实证检验了泰国制造业创新、研发和生产率之间的关系。我们利用一个简化的结构模型(CDM模型)来描述泰国案例中创新产出、研发和生产率之间的联系。使用各种估计技术来比较和为经验结果提供证据。研究结果表明,无论是在工艺创新还是产品创新方面,政府资助和企业特色对企业的研发和创新能力都起着重要作用。出口工厂、中部地区工厂、总公司类型的工厂更有可能从事研究开发(R&D)和创新。研究表明,产业类型和工厂的特定技术特征会影响创新努力和承担研发的决策。平均而言,工厂规模、外资所有权、出口和产品创新是泰国制造业生产率提高的重要驱动因素。
