This paper studies the potential association between two geographic indicators, distance and altitude, with the Multidimensional Poverty Index (MPI) for 1,874 district in Peru by using the National Census of 2017. We investigate whether higher altitude or longer distance is associated with higher MPI values. For this purpose, we use the distance of each district to three different potential spaces of reference. First, we use the shortest distance to the metropolitan area of Lima; second, the shortest distance to the capitals of coastal departments; third, and finally, the shortest distance to the sea. We obtain three relevant results. First, we find evidence that altitude is statistically significant and positive associated with variation of MPI among districts. Second, the distance with respect to the sea appears to be more relevant to explaining differences in MPI than the distance to the Metropolitan area or coastal departmental capitals. Finally, we find evidence of spatial externalities of MPI across districts which also seem to be stronger than the direct effect of altitude and distance.
本文利用2017年全国人口普查数据,对秘鲁1874个地区的多维贫困指数(MPI)与距离和海拔两个地理指标之间的潜在关联进行了研究。我们调查是否较高的海拔或较长的距离与较高的MPI值有关。为此,我们使用每个区域到三个不同潜在参考空间的距离。首先,我们使用距离利马市区最短的线路;二是与沿海省区省会距离最短;第三,也是最后一个,离大海最近的地方。我们得到了三个相关的结果。首先,我们发现海拔高度与地区间MPI变化呈显著正相关。其次,相对于海洋的距离似乎比与大都市地区或沿海省首府的距离更能解释MPI的差异。最后,我们发现跨地区MPI的空间外部性似乎也强于海拔和距离的直接影响。

This paper analyzes the impact of reducing output tariffs (i.e., domestic tariffs on import of final goods) and input tariffs (i.e., domestic tariffs on imports of intermediate goods) on total factor productivity growth of Peruvian manufacturing firms. Peru’s annual survey of manufacturing data from 2003–2017 is used to explore the reduction of tariffs during three preferential trade agreements: United States, China, and the European Union. Lower output tari˙s could decrease productivity by reducing firm’s market share or could increase productivity by inducing tougher import competition, while cheaper imported inputs can raise productivity via learning, variety, and quality effects. The results show that a decrease in output tariffs decreases Peruvian firms’ productivity growth for non-exporters (i.e., domestic firms producing goods that are also imported) while increasing productivity growth for exporters (i.e., domestic firms producing export goods). In contrast, a reduction in input tariffs increases firm productivity for all firms.
本文分析了降低产出关税(即成品进口国内关税)和投入关税(即中间产品进口国内关税)对秘鲁制造业企业全要素生产率增长的影响。秘鲁2003年至2017年的年度制造业数据调查用于探索美国、中国和欧盟三个优惠贸易协定期间关税的降低。较低的产出关税˙s可以通过减少企业的市场份额来降低生产率,或者通过引入更激烈的进口竞争来提高生产率,而更便宜的进口投入可以通过学习、品种和质量效应来提高生产率。结果表明,出口关税的降低降低了秘鲁公司对非出口商(即生产同样进口的商品的国内公司)的生产率增长,同时提高了出口商(即生产出口商品的国内公司)的生产率增长。相反,降低投入关税会提高所有企业的生产率。

Research examining small commercial and industrial electricity usage patterns have historically received less attention than residential electricity consumption patterns. This study examines electricity as an input to small firm commercial and industrial (CIS) production in Las Cruces, the second largest metropolitan economy in the state of New Mexico, using annual frequency data from 1978 to 2018. Those data include labor, per capita personal income, price measures for electricity and natural gas, and weather variables. The long-run and short-run elasticities of the data are then estimated using an autoregressive distributed lag model (ARDL). In the long-run, the CIS derived-demand curve is found to be upward sloping, and Las Cruces CIS customers use natural gas as a complementary input. Real per capita income is also found to have a positive impact in the long-run, while weather impacts are found to be ambiguous. In the short-run, the Las Cruces CIS derived-demand curve is downward sloping, CIS customers use natural gas as a substitute factor, and weather extremes are found to be positively correlated with small firm electricity usage.
对小型商业和工业用电模式的研究历来比住宅用电模式受到的关注少。本研究使用1978年至2018年的年度频率数据,对新墨西哥州第二大大都市经济体拉斯克鲁塞斯的小型企业商业和工业(CIS)生产的电力投入进行了调查。这些数据包括劳动力、人均个人收入、电力和天然气价格指标以及天气变量。然后使用自回归分布滞后模型(ARDL)估计数据的长期和短期弹性。从长期来看,CIS的推导需求曲线是向上倾斜的,Las Cruces的CIS客户使用天然气作为补充输入。实际人均收入也被发现在长期内有积极的影响,而天气的影响被发现是模糊的。在短期内,Las Cruces CIS的推导需求曲线是向下倾斜的,CIS客户使用天然气作为替代因素,并且发现极端天气与小型企业用电量呈正相关。

Poverty, population growth and agglomeration effects in all Brazil cities 巴西所有城市的贫困、人口增长和集聚效应
Pub Date : 2023-08-22 DOI: 10.1108/econ-11-2022-0163

PurposeThis paper aims to test three hypotheses in city growth literature documenting the poverty reduction observed in Brazil and exploring a rich spatial dataset for 5,564 Brazilian cities observed between 1991 and 2010. The large sample and the author's improved econometric methods allows one to better understand and measure how important income growth is for poverty reduction, the patterns of agglomeration and population growth in all Brazilian cities.Design/methodology/approachThe author identifies literature gaps and use a sizeable spatial dataset for 5,564 Brazilian cities observed in 1991, 2000 and 2010 applying instrumental variables methods. The bias-corrected accelerated bootstrap percentile interval supports the author's point estimates.FindingsThis manuscript finds that Brazilian data for cities does not support Gibrat's law, raising the scope for urban planning and associated policies. Second, economic growth on a sustainable basis is still a vital source of poverty reduction (The author estimates the poverty elasticity at four percentage points). Lastly, agglomeration effects positively affect the city's productivity, while negative externalities underlie the city's development patterns.Originality/valueData for cities in Brazil possess unique characteristics such as spatial autocorrelation and endogeneity. Applying proper methods to find more reliable answers to the above three questions is a desirable procedure that must be encouraged. As the author points out in the manuscript, dealing with endogenous regressors in regional economics is still a developing matter that regional scientists could more generally apply to many regional issues.
本文旨在验证巴西城市增长文献中的三个假设,并探索1991年至2010年间巴西5564个城市的丰富空间数据集。大样本和作者改进的计量经济学方法使人们能够更好地理解和衡量收入增长对减少贫困、集聚模式和巴西所有城市人口增长的重要性。设计/方法/方法作者确定了文献空白,并使用了一个相当大的空间数据集,其中包括1991年、2000年和2010年使用工具变量方法观察的5564个巴西城市。经过偏差校正的加速自举百分位数区间支持作者的点估计。本文发现,巴西的城市数据不支持直布罗陀的法律,这增加了城市规划和相关政策的范围。其次,可持续基础上的经济增长仍然是减少贫困的重要来源(作者估计贫困弹性为4个百分点)。最后,集聚效应正向影响城市生产力,而负外部性影响城市发展模式。巴西城市原创性/价值数据具有空间自相关性和内生性等独特特征。运用适当的方法找到以上三个问题的更可靠的答案是一个必须鼓励的理想过程。正如作者在手稿中指出的那样,处理区域经济学中的内生回归因子仍然是一个发展中的问题,区域科学家可以更普遍地应用于许多区域问题。

PurposeThis paper investigates the factors crucial for small and medium enterprises (SMEs) in establishing business relationships with banks in Pakistan.Design/methodology/approachTo investigate how SMEs select banking relationships using criteria, such as decision factors, decision-makers, and decision processes, a comprehensive literature review was used to classify SMEs' decision factors for bank selection. A survey questionnaire was distributed to 200 SMEs, randomly selected from the Small and Medium Enterprise Development Authority database in Pakistan. Probit/Tobit model is estimated to explain the behavior of SMEs.FindingsThe results reveal that SMEs consider a bank's Reputation, Price, and Location essential while establishing bank relationships. SMEs tend to terminate relationships with banks when the Price and Location of the bank are considered essential factors in the relationship with the banks. Price and Location are necessary for SMEs to reduce banking relationships. The SMEs also tend to reduce if they get attractive offers, or the SMEs are recommended to make a banking relationship. This study also provides intuitions for bank policymakers to design policies to retain SME customers and attract new business relationships.Practical implicationsThe research emphasizes the importance of competitive and transparent pricing strategies in designing products for SMEs. Banks must prioritize their Reputation and credibility to attract and retain relationships with SMEs.Originality/valueThe study attempts to provide evidence on the SME-Bank relationship focusing on the factors that are crucial for SMEs to decide while establishing business relationships with banks. Also, most of the related literature focuses on developed countries; this research adds to the literature on SMEs' behavior, particularly in a developing country's context.
目的本文调查了在巴基斯坦与银行建立业务关系的中小企业(SMEs)的关键因素。设计/方法/方法为了调查中小企业如何使用决策因素、决策者和决策过程等标准选择银行关系,我们使用了一项全面的文献综述来对中小企业选择银行的决策因素进行分类。向从巴基斯坦中小企业发展局数据库中随机选出的200家中小企业分发了调查问卷。估计Probit/Tobit模型可以解释中小企业的行为。结果显示,中小企业在与银行建立关系时,认为银行的声誉、价格和地理位置至关重要。当银行的价格和地理位置被认为是影响中小企业与银行关系的重要因素时,中小企业倾向于终止与银行的关系。价格和地理位置是中小企业减少银行关系的必要条件。如果中小企业获得有吸引力的报价,或者建议中小企业建立银行关系,中小企业也倾向于减少。本研究也为银行决策者设计政策以保留中小企业客户和吸引新的业务关系提供了直觉。实践意义本研究强调了竞争性和透明定价策略在中小企业产品设计中的重要性。银行必须优先考虑其声誉和信誉,以吸引和保持与中小企业的关系。独创性/价值本研究试图为中小企业与银行的关系提供证据,重点关注中小企业在与银行建立业务关系时决定的关键因素。此外,大多数相关文献都集中在发达国家;这项研究增加了关于中小企业行为的文献,特别是在发展中国家的背景下。

PurposeThis study aims to analyze the contagious effects of economic policy uncertainties in the USA on the economies of its important trading partners, such as Japan, Canada, Mexico and the Eurozone.Design/methodology/approachIn the study using the uncertainty index created by Baker et al. (2016), the interaction between variables was analyzed with structural VAR (SVAR) models.FindingsAccording to the results obtained from the analysis, economic policy uncertainties in the USA had significant effects on the economies of its high-volume trading partners. The internal debt crisis experienced in the Eurozone after the 2008 crisis caused the European Central Bank to respond to the economic policy uncertainties in the USA with contractionary monetary policies, unlike other countries. In addition to these results, Mexico, which has a more fragile economic structure than other countries in the analysis, was more impacted by increasing uncertainties, as expected.Originality/valueThe present study aimed to bring a new perspective to the literature by evaluating the contagiousness of local uncertainty in the globalizing world and the monetary policies implemented as a precaution against this situation on an empirical plane.
本研究旨在分析美国经济政策不确定性对其重要贸易伙伴(如日本、加拿大、墨西哥和欧元区)经济的传染效应。在使用Baker等人(2016)创建的不确定性指数的研究中,使用结构VAR (SVAR)模型分析变量之间的相互作用。根据分析得出的结果,美国经济政策的不确定性对其大量贸易伙伴的经济产生了重大影响。2008年危机后欧元区经历的内部债务危机导致欧洲央行与其他国家不同,以紧缩的货币政策来应对美国经济政策的不确定性。除此之外,正如预期的那样,墨西哥的经济结构比分析中的其他国家更脆弱,受不确定性增加的影响更大。原创性/价值本研究旨在通过在经验层面上评估全球化世界中局部不确定性的传染性以及作为预防这种情况而实施的货币政策,为文献带来新的视角。

The effect of small-scale changes in wealth on risk attitudes: an experimental study 财富的小规模变化对风险态度的影响:一项实验研究
Pub Date : 2023-07-28 DOI: 10.1108/econ-09-2022-0132
Sergio Almeida
PurposeThis study aims to examine the effects of prior small-scale changes to wealth on subsequent risky choices.Design/methodology/approachThe paper opted for a laboratory experiment in which subjects perform two sequences of risky tasks. In between these two sets, the author transfers money for real for a randomly selected half of the subjects. Data on choices before and after the transfer of money are used to estimate risk attitudes and analyze whether the transfer of money affected attitudes to risk.FindingsThe author finds that the money gain does not change subjects' risk preferences – neither in a within- nor in a between-subject design. This suggests that individuals' risky choices are consistent with their constant absolute (CARA) risk aversion preferences, a result that supports a key assumption in recent literature on the calibration critique of decision theories and the view that individuals engage in narrow framing.Research limitations/implicationsBecause of the relatively small transfer of money, the research results may lack generalizability.Practical implicationsThe paper includes implications for the reference-dependent and other theories that explain how prior outcomes affect risk-taking behavior in sequential problems.Social implications The results are relevant to the research community studying risk-taking behavior as the results shed new light on a well-known result put forward by a seminal paper by Thaler.Originality/valueThis paper fills in an identified gap in the literature which is the need to test the house-money effect in a more realistic setting (over repeated risk-elicitation tasks, with money given outside the lotteries and in a within-subject design).
目的:本研究旨在考察先前的小规模财富变化对随后的风险选择的影响。设计/方法/方法本文选择了一个实验室实验,在这个实验中,受试者执行两组有风险的任务。在这两组之间,作者为随机选择的一半受试者转账。资金转移前后的选择数据用于估计风险态度,并分析资金转移是否影响对风险的态度。研究结果作者发现,金钱收益不会改变受试者的风险偏好——无论是在受试者内部还是在受试者之间的设计中。这表明个体的风险选择与他们的恒定绝对(CARA)风险厌恶偏好是一致的,这一结果支持了最近关于决策理论校准批评的文献中的一个关键假设,以及个体参与窄框架的观点。研究局限性/意义由于资金转移相对较小,研究结果可能缺乏普遍性。实际意义本文包括对参考依赖理论和其他理论的启示,这些理论解释了先前结果如何影响序列问题中的冒险行为。这些结果与研究冒险行为的研究界有关,因为这些结果为塞勒在一篇开创性论文中提出的一个众所周知的结果提供了新的视角。原创性/价值本文填补了文献中的空白,即需要在更现实的环境中测试房屋资金效应(在重复的风险引出任务中,在彩票之外和在主题内设计中提供资金)。

PurposeThis study analyzes the role of migrant networks in the migration flows in relation to the educational level of the migrants and economic growth of the states of origin and destination in Brazil.Design/methodology/approachFixed effects estimator applied to microdata.FindingsThe results show migrant networks have a significant and positive impact on migration flows of the different educational levels. The economic growth in the destination state accentuates this effect, while the economic growth in the origin state has distinct impacts according to the educational level of the new migrant.Originality/valueThe authors investigate the importance of migrant networks in the internal immigration within a developing country with large internal movement of people. In Brazil, the socio-economic condition of the population varies considerably in relation to its geography, which explains the country’s large internal migration flows.
本研究分析了移民网络在移民流动中与移民教育水平和巴西原籍国和目的地国经济增长有关的作用。设计/方法/方法应用于微数据的固定效应估计器。结果表明,移民网络对不同教育水平的移民流动具有显著的正向影响。目的国的经济增长加剧了这种影响,而原籍国的经济增长根据新移民的教育水平有不同的影响。原创性/价值作者调查了移民网络在具有大量内部人口流动的发展中国家内部移民中的重要性。在巴西,人口的社会经济状况因其地理位置而有很大差异,这解释了该国大量的国内移徙流动。

Non-tradables in Brazilian economic history 巴西经济史上的非贸易品
Pub Date : 2023-06-06 DOI: 10.1108/econ-12-2022-0189

PurposeThe purpose is to market a reinterpretation of Brazilian economic history highlighting the importance of non-tradable goods to understand major historical developments such as the lack of industrialization in the mining boom; the rise and contribution of industries to development in the early 20th century; indexation as hyperinflation in the late 20th century; growth and cycles in the early 21st century.Design/methodology/approachSection 2 introduces analytical perspectives on the relationship between non-tradables, transport costs and external shocks. Section 3 presents a historical overview of the gold and coffee cycles in the Brazilian economy, which highlights the crucial role played by transport costs in the genesis of industrialization. Thus, in a more precise way, industrialization was not an import substitution process but the substitution of non-tradables by the domestic tradable manufactures.FindingsSection 4 shows that Brazilian statistical records and historiography disregard this characterization and, to that extent, underestimate economic growth in the primary export phase (1872–1920) and overestimate growth rates in the industrialization period (1920–1940). Section 5 shifts to the end of the 20th century to analyze the relationship between non-tradables, indexation and hyperinflation. Section 6 concludes with a brief discussion of the role played by the terms of trade and non-tradables in the unfolding of the 2014 economic crisis.Originality/valueDistance from international markets and a continental geographic size made transport costs in Brazil historically prohibitive: the relevance of non-tradables in the Brazilian economic history. While the theme is not new, it seldom received proper attention in the historiography.
目的:目的是市场对巴西经济史的重新解释,强调非贸易商品的重要性,以了解主要的历史发展,如矿业繁荣时期缺乏工业化;20世纪初工业的兴起及其对经济发展的贡献指数化是20世纪末的恶性通货膨胀;21世纪初的增长和周期。设计/方法/方法第2节介绍了对非贸易品、运输成本和外部冲击之间关系的分析观点。第3节介绍了巴西经济中黄金和咖啡周期的历史概况,强调了运输成本在工业化起源中所起的关键作用。因此,更准确地说,工业化不是一个进口替代过程,而是国内可贸易制成品替代不可贸易制成品的过程。第4节的研究结果表明,巴西的统计记录和历史编纂忽略了这一特征,并在一定程度上低估了初级出口阶段(1872-1920)的经济增长,高估了工业化时期(1920-1940)的增长率。第五节转到20世纪末,分析非贸易品、指数化和恶性通货膨胀之间的关系。第6节最后简要讨论了贸易条件和非贸易条件在2014年经济危机中所起的作用。原创性/价值距离国际市场的距离和大陆的地理面积使巴西的运输成本在历史上令人望而却步:巴西经济史上不可贸易品的相关性。虽然这一主题并不新颖,但在史学研究中却很少受到重视。

Impact of fiscal deficit and trade openness on current account deficit in India: new evidence on twin deficits hypothesis 财政赤字和贸易开放对印度经常账户赤字的影响:双赤字假说的新证据

PurposeThis study aims to examine the impact of fiscal deficit, exchange rate and trade openness on current account deficit (CAD). The study tried to empirically investigate the ‘twin deficits hypothesis’ and ‘compensation hypothesis’ in the Indian context.Design/methodology/approachAutoregressive distributed lagARDL) bound test approach was used by taking annual time series data from 1978 to 2021. The estimates confirm a significant long-run and short-run relationship between dependent variables, i.e. CAD and independent variables such as the fiscal deficit, exchange rate and trade openness.FindingsThe results show that positive shocks of all explanatory variables significantly affect the CAD. CAD and fiscal deficit are significantly associated, as the coefficient of fiscal deficit is positive and significant. The study also found that exchange rate and trade openness significantly affect the CAD. The coefficients of exchange rate and trade openness are positive and significant. The findings show that an increase in CADs results from liberal trade policies that help domestic industries grow their trade and expansionary fiscal policy, leading to a higher fiscal deficit. The negative and significant error correction term suggests that short-run disequilibrium converges to long-run equilibrium at a speed of 19.2%. The findings validate the ‘twin deficits hypothesis’ and ‘compensation hypothesis’ in the Indian context.Practical implicationsIt can be inferred from the study that liberal policy to promote economic growth and trade openness should be designed and promoted judiciously. An excessive liberalised approach may impact other macroeconomic variables such as current account balances. Integrating the domestic market with global markets poses a big challenge for countries like India that aspire to penetrate global markets. Furthermore, the Indian policy makers should rigorously work and promote the policies such as Fiscal Responsibility and Budget Management (FRBM) as reduction in fiscal deficits, trade imbalances will also be reduced.Originality/valueThis study contributes to the existing literature on ‘twin deficit’ and trade openness by giving new evidence on the trilemma between designing sustainable fiscal policy by spending wisely without imperilling the country's global presence and CAD.
目的探讨财政赤字、汇率和贸易开放对经常账户赤字的影响。本研究试图对印度背景下的“双缺陷假说”和“补偿假说”进行实证研究。设计/方法/方法采用回归分布lagARDL边界检验方法,选取1978 - 2021年的年度时间序列数据。这些估计证实因变量(即加元)与自变量(如财政赤字、汇率和贸易开放程度)之间存在显著的长期和短期关系。结果表明,所有解释变量的正冲击显著影响CAD。CAD与财政赤字显著相关,财政赤字系数为正且显著。研究还发现,汇率和贸易开放度对加元有显著影响。汇率与贸易开放度的系数正且显著。研究结果表明,帮助国内产业扩大贸易的自由贸易政策和扩张性财政政策导致了财政赤字的增加。负且显著的误差修正项表明,短期不均衡以19.2%的速度收敛于长期均衡。研究结果在印度的背景下验证了“双缺陷假说”和“补偿假说”。实践启示:促进经济增长和贸易开放的自由主义政策应审慎设计和推行。过度自由化的做法可能会影响其他宏观经济变量,如经常账户余额。对于像印度这样渴望打入全球市场的国家来说,将国内市场与全球市场整合起来是一个巨大的挑战。此外,印度的政策制定者应该严格工作,促进财政责任和预算管理(FRBM)等政策,以减少财政赤字,贸易不平衡也将减少。原创性/价值本研究为“双赤字”和贸易开放的现有文献提供了新的证据,证明了在不危及国家全球存在和CAD的情况下,通过明智地支出来设计可持续财政政策之间的三困境。
