ABSTRACT: There are contradicting views regarding the casual nexus between a country's military spending and its nation's income inequality. Military spending is a critical component of government budget and can simply crowd out transfer payments, needed to improve income inequality. However, these payments can also stimulate a demand that can enhance the income prospects of the low-income earners. So, the association between military spending and income inequality is a vital question. The aim of this study is to examine the relationship between military spending and income inequality for BRICS countries (Brazil, Russia, India, China and South Africa). We used panel data extracted from different sources such as World Bank's World Development Indicators and Penn World Tables. This is the first study that disaggregate the data and compute the results for the full sample (all BRICS countries taken together) and for sub-samples for countries with military expenditure of about 2% of GDP (India, china and Russia) and countries with military expenditure of less than 1% of GDP (that is, South Africa and Brazil). Thus, to unravel the influence of military spending on income inequality, pool mean group (PMG) or panel autoregressive distributed lag (PARDL) approach was applied for the period from 1990–2017 for BRICS nations. Overall, the empirical result for the pooled sample established an inverse relationship between military expenditure and income inequality. A percentage change in military expenditure result in income inequality reduction within the BRICS community. The estimated coefficient of GDP per capita, show that a percentage increase in GDP per capita in the long run will lead to about -0.209756 reduction in the level of income inequality and statistically significant at 1% level. When data was disaggregated to reflect the BRICS countries whose military expenditure was about 2% of the national budget (i.e. Russia, China and India), the study found that military expenditure had a negative influence on income inequality in the long run equation. Based on the outcome of this empirical work, we recommend for policy makers should focus more on the policies which can improve economic activities within the BRICS nations and ultimately reduce income inequality.
摘要:一个国家的军费开支与其收入不平等之间存在着相互矛盾的关系。军费开支是政府预算的重要组成部分,可能会挤掉改善收入不平等所需要的转移支付。然而,这些支付也可以刺激需求,从而提高低收入者的收入前景。因此,军费开支和收入不平等之间的关系是一个至关重要的问题。本研究的目的是研究金砖国家(巴西、俄罗斯、印度、中国和南非)军费开支与收入不平等之间的关系。我们使用了从不同来源提取的面板数据,如世界银行的世界发展指标和宾夕法尼亚大学的世界表。这是第一次将数据分解并计算整个样本(所有金砖国家加在一起)的结果,以及军费开支占GDP的2%左右的国家(印度、中国和俄罗斯)和军费开支占GDP的不到1%的国家(即南非和巴西)的子样本。因此,为了揭示军费开支对收入不平等的影响,我们在1990年至2017年期间对金砖国家采用了池均值组(PMG)或面板自回归分布滞后(PARDL)方法。总体而言,合并样本的实证结果建立了军费支出与收入不平等之间的反比关系。军费开支的百分比变化导致金砖国家社区内收入不平等的减少。估算的人均GDP系数表明,从长期来看,人均GDP每增加一个百分点,收入不平等水平将降低约-0.209756,在1%的水平上具有统计学意义。当数据被分解以反映军费开支约占国家预算2%的金砖国家(即俄罗斯、中国和印度)时,研究发现,从长期来看,军费开支对收入不平等有负面影响。基于这一实证工作的结果,我们建议政策制定者应该更多地关注能够改善金砖国家内部经济活动并最终减少收入不平等的政策。

ABSTRACT: The rapid economic progress of Bangladesh is associated with a swiftly rising demand and energy consumption. Future economic growth will undoubtedly require a proportionate increase in energy availability within affordable prices. Bangladesh is inherently energy-scarce and heavily dependent on imported energy, primarily fossil fuels. Several approaches and strategies were attempted over time to mitigate the energy shortage. Some of them were reasonably successful, while others failed. In this study, we first examine the historical developments of the energy sector in Bangladesh since its independence and then use three approaches – triple exponential smoothing, vector autoregression, and the Cochrane-Orcutt AR(1) process to forecast the energy demand. Data for this study were taken from various sources, including British Petroleum, International Gas Union, International Energy Agency, Bangladesh Bureau of Statistics, World Bank, Petrobangla, and Energy Information Agency of the United States. As expected, each model predicts an exponential growth of energy demand in Bangladesh. We then explored the possibilities of mitigating such projected energy demand. Various studies show that Bangladesh has some potential for producing energy from renewable sources, i.e., solar, hydro, wind, wave, and others. However, such possibilities are limited, and many are still in their infancy. Although an increase in renewable energy is desirable from an environmental perspective, it alone will not meet Bangladesh's growing energy demand. At least in the short term, Bangladesh must rely on imported fossil energy. Among the fossil energy sources, LNG is by far the cleanest. With the development of technology, liquefaction, transportation, and regasification, LNG production, transportation, and use are becoming less expensive. Progressively more natural gas-producing countries are joining LNG production and export, contributing to the market's competitiveness. Though historically tied to the oil market, LNG markets are becoming more and more independent because of the increasing number of participants from both the demand and supply sides. Given that both its global price and negative impact on the environment are relatively lower than other fossil fuels, imported LNG should be the fuel of choice for Bangladesh. Government policies should focus on both importing LNG and expanding renewable energy resources.
摘要:孟加拉国经济的快速发展与能源需求和消费的快速增长密不可分。未来的经济增长无疑需要在可承受的价格范围内按比例增加能源供应。孟加拉国天生能源匮乏,严重依赖进口能源,主要是化石燃料。随着时间的推移,人们尝试了几种方法和策略来缓解能源短缺。其中一些相当成功,而另一些则失败了。在本研究中,我们首先考察了孟加拉国自独立以来能源部门的历史发展,然后使用三种方法-三重指数平滑,向量自回归和Cochrane-Orcutt AR(1)过程来预测能源需求。本研究的数据来自各种来源,包括英国石油公司、国际天然气联盟、国际能源署、孟加拉国统计局、世界银行、孟加拉国国家石油公司和美国能源信息署。正如预期的那样,每个模型都预测了孟加拉国能源需求的指数增长。然后,我们探讨了减轻这种预计能源需求的可能性。各种研究表明,孟加拉国在利用可再生能源生产能源方面具有一定的潜力,例如太阳能、水能、风能、潮汐能等。然而,这种可能性是有限的,而且许多仍处于起步阶段。虽然从环境的角度来看,增加可再生能源是可取的,但仅凭这一点并不能满足孟加拉国日益增长的能源需求。至少在短期内,孟加拉国必须依赖进口化石能源。在化石能源中,液化天然气是迄今为止最清洁的。随着技术的发展,液化、运输和再气化,液化天然气的生产、运输和使用成本越来越低。越来越多的天然气生产国正在逐步加入液化天然气的生产和出口,这有助于提高市场的竞争力。尽管历史上与石油市场联系在一起,但由于需求和供应双方的参与者越来越多,液化天然气市场正变得越来越独立。考虑到其全球价格和对环境的负面影响都相对低于其他化石燃料,进口液化天然气应该是孟加拉国的首选燃料。政府的政策应侧重于进口液化天然气和扩大可再生能源。

ABSTRACT: This paper investigates export spillovers from foreign direct investment on the exporting activities of domestic manufacturing firms in Kenya. Specifically, the paper aims at identifying the transmission channels through which foreign direct investment affects the export propensity and export intensity decisions of domestically-owned firms. The study also examines the importance of firm-level heterogeneity on the occurrence and behavior of spillover channels. The study uses a panel data set for manufacturing firms in Kenya, obtained from the World Bank Enterprise Surveys, conducted in three waves covering the period 2007–2018. Employing the Double-Hurdle model approach, and using the maximum likelihood estimation technique, we empirically demonstrate the relevance and significance of distinguishing three channels for intra-industry (horizontal) spillovers – demonstration effects, information effects and competition effects channels and one channel for vertical spillovers, that is, backward linkage channel. Findings of this study shows that domestically-owned firms in Kenya experience significant positive export spillovers on their export participation decisions through the demonstration effects channel and significant negative spillovers via the competition effects channel. The findings also show significant positive export spillover effects on the export intensity decisions of domestically-owned firms via information and competition effects channels and significant negative export spillover effects via the backward linkages channel. The results further provide evidence that firms belonging to industries with low technological levels were unable to absorb spillover benefits from foreign presence via the demonstration effects channel. The results also indicate that small and medium firms were unable to reap export spillovers benefits via information effects and backward linkage channels. The findings have important policy implications for managers of firms and policymakers in Kenya and other developing countries. To enhance export-related spillover benefits, domestic firms need to enhance their absorptive capacities by upgrading their technical capacities and improving quality standards. Governments should facilitate the exchange of information on investor needs, their capacities and skills requirements, thus bridging information gaps between domestic suppliers and foreign investors in addition to supporting domestic market linkages.
摘要:本文研究外商直接投资对肯尼亚国内制造业出口活动的出口溢出效应。具体而言,本文旨在确定外国直接投资影响内资企业出口倾向和出口强度决策的传导渠道。研究还考察了企业层面异质性对溢出渠道发生和行为的重要性。该研究使用了从世界银行企业调查中获得的肯尼亚制造业企业的面板数据集,该调查分三波进行,涵盖2007-2018年。本文运用双栏模型方法,运用最大似然估计技术,实证论证了区分产业内(横向)溢出效应的三个渠道——示范效应、信息效应和竞争效应渠道,以及纵向溢出效应的一个渠道——反向联动渠道的相关性和重要性。研究发现,肯尼亚内资企业通过示范效应渠道对其出口参与决策产生显著的正向溢出效应,通过竞争效应渠道对其出口参与决策产生显著的负向溢出效应。研究结果还表明,信息和竞争效应渠道对内资企业出口强度决策具有显著的正向外溢效应,而后向联系渠道对内资企业出口强度决策具有显著的负向外溢效应。研究结果进一步证明,技术水平较低的产业企业无法通过示范效应渠道吸收外资的溢出效益。结果还表明,中小企业无法通过信息效应和落后的联系渠道获得出口溢出效益。这些发现对肯尼亚和其他发展中国家的企业管理者和决策者具有重要的政策意义。为了提高与出口相关的溢出效益,国内企业需要通过提升技术能力和提高质量标准来提高吸收能力。各国政府应促进交流关于投资者需要、能力和技能要求的资料,从而除了支持国内市场联系外,还应缩小国内供应商和外国投资者之间的资料差距。

ABSTRACT: The world has gone through various economic crises in the past century, and their effects have had varying implications on the economies of countries all over the world. In a bid to help stabilise economies all over the world, various measures have been put in place. Some of these measures include regulations and policies by the Bretton Woods institutions (World Bank and International Monetary Fund) and their agencies. The idea behind these measures is to ensure sustainable growth and development among member states and other countries of the world. Some of these policies include the privatization and liberalization policies of the Bretton Woods institutions as well as other policies bordering on such economic and social benefits for people all over the world. The Nigerian economy in our contemporary time can be described as passing through a rather 'volatile' phase with respect to interest rate, financial development and foreign capital inflow. Thus, this study investigated the impact of interest rate spread and financial development on foreign capital inflow in Nigeria. Several studies have been carried out using different methodologies, such as; co-integration equation, multivariate vector auto regressive (VAR) model and vector error correction technique. Each methodology used was in line with the objective of the research in question. However, to achieve its objective, this paper adopted the Classical Linear Regression Model. The results of the study showed that financial development has a positive impact on foreign capital inflow, while interest rate spread on the other hand, was also found to have a positive impact on foreign capital inflow. Other control variables such as market capitalization and treasury bills rate were also found to positively affect foreign capital inflow, while the all share index had a negative impact on foreign capital inflow. Some economists have opined that the Nigerian economy is currently going through a phase of recession. In order for large scale investments to be made within the country, there is a need for foreign participants to be attracted to the Nigerian economy and pull their resources, both financial and non-financial into the country (but, not without regulation). However, for these investors to have confidence to make investments in the Nigerian economy, there has to be a high degree of economic stability in the country. This can be supported by enacting and implementing policies that can enhance the quality of interest rates spread and financial development within the country. The policy implication here involves enhancing financial development through sound policies and adopting competitive interest rates, could increase the rate of foreign inflow into the economy. In view of this, it is also recommended that government policies should target interest rate competitiveness, financial and economic development as well as sustainability.
摘要:在过去的一个世纪里,世界经历了各种各样的经济危机,其影响对世界各国的经济产生了不同的影响。为了帮助稳定世界各地的经济,各种措施已经到位。其中一些措施包括布雷顿森林机构(世界银行和国际货币基金组织)及其机构的规章和政策。这些措施背后的理念是确保成员国和世界其他国家之间的可持续增长和发展。其中一些政策包括布雷顿森林机构的私有化和自由化政策,以及为全世界人民提供这种经济和社会利益的其他政策。我们当代的尼日利亚经济可以说是在利率、金融发展和外国资本流入方面经历了一个相当“不稳定”的阶段。因此,本研究考察了利差和金融发展对尼日利亚外资流入的影响。使用不同的方法进行了几项研究,例如;协整方程,多元向量自回归(VAR)模型和向量误差校正技术。所使用的每一种方法都符合有关研究的目的。然而,为了达到目的,本文采用了经典线性回归模型。研究结果表明,金融发展对外资流入有正向影响,另一方面,利率息差对外资流入也有正向影响。其他控制变量如市值和国库券利率也对外资流入有正向影响,而所有股票指数对外资流入有负向影响。一些经济学家认为,尼日利亚经济目前正处于衰退阶段。为了在国内进行大规模投资,有必要吸引外国参与者参与尼日利亚经济,并将他们的金融和非金融资源带入该国(但并非没有监管)。然而,要让这些投资者有信心投资尼日利亚经济,该国必须有高度的经济稳定。可以通过制定和实施能够提高国内利差和金融发展质量的政策来支持这一点。这里的政策含义包括通过健全的政策和采用有竞争力的利率来加强金融发展,可以增加外国流入经济的速度。有鉴于此,建议政府政策应以利率竞争力、金融和经济发展以及可持续性为目标。

ABSTRACT: African countries suffer from the negative effects of climate change more severely compared to other continents, despite contributing only a small fraction of the global carbon emissions. This is attributed to at least three factors. First, Africa relies heavily on solid fuel energy sources to meet its socioeconomic needs. The use of solid fuels is associated with heavy pollution, which exposes the population to significant health risks. Second, environmental policy is less successful on the continent owing to the uncertainty caused by a lack of understanding of the scope of the environmental problem. Third, the African continent has become heedless about the consequences of climate change in its ambition for further growth to catch up with the rest of the world. In this study, we examined the roles of energy consumption and governance in explaining the carbon Kuznets curve hypothesis in African countries from 1995 to 2019. The empirical evidence provided is based on second-generation time-series analysis that accounts for cross-sectional dependency among the assessed factors. Specifically, the Westerlund cointegration approach, Cross-sectional Autoregressive Distributed Lag (CS-ARDL) simulation, Augmented Mean Group (AMG) method, and Dumitrescu and Hurlin heterogeneous panel causality tests were implemented. Together, these results confirm the validity of the CKC hypothesis for Africa. The mechanisms through which economic growth affects carbon emissions have been identified as energy consumption and governance. While it is possible to achieve a significant reduction in carbon emissions in Africa using environmental policy, there is a need to sacrifice growth to achieve desirable environmental quality. Governance arrangements need to be transparent and accountability regarding carbon regulations needs to be taken seriously. Promoting sustainable growth across Africa is important because it holds the key to accelerating global action. We recommend effective regulatory compliance monitoring and enforcement while reducing carbon emissions and advancing sustainable development through energy transitions.
摘要:尽管非洲国家的碳排放量只占全球碳排放量的一小部分,但与其他大陆相比,非洲国家受到气候变化的负面影响更为严重。这至少归因于三个因素。首先,非洲严重依赖固体燃料能源来满足其社会经济需求。固体燃料的使用与严重污染有关,使人口面临严重的健康风险。其次,由于对环境问题的范围缺乏了解而造成的不确定性,环境政策在非洲大陆不太成功。第三,非洲大陆在追求进一步发展以追赶世界其他地区的雄心中,已经对气候变化的后果漠不关心。在这项研究中,我们研究了1995年至2019年非洲国家能源消费和治理在解释碳库兹涅茨曲线假设中的作用。所提供的经验证据是基于第二代时间序列分析,该分析考虑了被评估因素之间的横截面依赖性。具体而言,实施了Westerlund协整方法、横断面自回归分布滞后(CS-ARDL)模拟、增强平均组(AMG)方法以及Dumitrescu和Hurlin异质性面板因果关系检验。总之,这些结果证实了非洲CKC假设的有效性。经济增长影响碳排放的机制已被确定为能源消耗和治理。虽然利用环境政策有可能大幅度减少非洲的碳排放,但必须牺牲增长来实现理想的环境质量。治理安排需要透明,有关碳监管的问责制需要认真对待。促进整个非洲的可持续增长非常重要,因为它是加速全球行动的关键。我们建议在减少碳排放和通过能源转型促进可持续发展的同时,有效地监测和执行法规遵从情况。

In this study, we examined the roles of energy consumption and governance in explaining the carbon Kuznets curve hypothesis in African countries from 1995 to 2019. The empirical evidence provided is based on second-generation time-series analysis that accounts for cross-sectional dependency among the assessed factors. Specifically, the Westerlund cointegration approach, Cross-sectional Autoregressive Distributed Lag (CS-ARDL) simulation, Augmented Mean Group (AMG) method, and Dumitrescu and Hurlin heterogeneous panel causality tests were implemented. Together, these results confirm the validity of the CKC hypothesis for Africa. The mechanisms through which economic growth affects carbon emissions have been identified as energy consumption and governance. While it is possible to achieve a significant reduction in carbon emissions in Africa using environmental policy, there is a need to sacrifice growth to achieve desirable environmental quality. Governance arrangements need to be transparent and accountability regarding carbon regulations needs to be taken seriously. Promoting sustainable growth across Africa is important because it holds the key to accelerating global action. We recommend effective regulatory compliance monitoring and enforcement while reducing carbon emissions and advancing sustainable development through energy transitions.","PeriodicalId":84983,"journal":{"name":"Journal Of Developing Areas","volume":"253 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135145116","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}

ABSTRACT: This study examines the factors contributing to developing subsidiary knowledge in Malaysian foreign subsidiaries. Prior research on subsidiaries in multinational corporations has either concentrated on transferring knowledge from headquarters to subsidiaries or vice versa, ignoring the factors associated with subsidiary knowledge development through embedded relationship factors. Although embedded relations are essential for developing knowledge, the direction is most important for developing subsidiary knowledge. The significance of subsidiary knowledge development, subsidiary autonomy, and external and internal embeddedness has been poorly illuminated by prior research. This is because the perception of knowledge development is emphasized from the headquarters' perspective, while the subsidiary functions as a passive recipient. Using the resource-based and network theories, we argue that subsidiary development depends on the subsidiary's autonomy practice and the level of engagement or network relations between external and internal network partners. Our research shows that subsidiary autonomy and external embeddedness are the most significant predictors of subsidiary knowledge development. Internal embeddedness in subsidiary knowledge development is inconsistent with the theoretical assumptions for subsidiary autonomy and external embeddedness. In regression analysis, the survey results of 170 foreign-owned subsidiaries in Malaysia validate our hypotheses. According to the results of this study, subsidiary autonomy and external and internal embeddedness are the most significant predictors of subsidiary knowledge development. This study's findings have implications for subsidiary administrators in developing nations and multinational corporations. While subsidiaries are developing their knowledge, multinationals need to consider how much autonomy to offer them in this process. When subsidiaries are able to make independent decisions, embedded relationships will increase, and knowledge will be more likely to develop. This specific knowledge eventually contributes to the knowledge base of the MNE.
摘要:本研究旨在探讨马来西亚外资子公司子公司知识发展的影响因素。以往对跨国公司子公司的研究要么集中在总部知识向子公司的转移,要么集中在子公司知识向总部知识的转移,而通过嵌入关系因素忽略了影响子公司知识发展的因素。虽然嵌入式关系对于知识的发展是必不可少的,但对于辅助知识的发展方向是最重要的。子公司知识发展、子公司自主、外部嵌入和内部嵌入的意义在以往的研究中都没有得到很好的阐释。这是因为从总部的角度强调知识发展的感知,而附属机构则是一个被动的接受者。利用资源基础理论和网络理论,我们认为子公司的发展取决于子公司的自主实践以及外部和内部网络伙伴之间的参与或网络关系水平。研究表明,子公司自主性和外部嵌入性是子公司知识发展最显著的预测因子。子公司知识发展的内部嵌入性与子公司自主和外部嵌入性的理论假设不一致。在回归分析中,对马来西亚170家外资子公司的调查结果验证了我们的假设。本研究结果显示,子公司自主性、外部嵌入性和内部嵌入性是子公司知识发展最显著的预测因子。本研究结果对发展中国家和跨国公司的子公司管理人员具有启示意义。在子公司发展知识的同时,跨国公司需要考虑在这一过程中给予它们多大的自主权。当子公司能够独立决策时,嵌入式关系将会增加,知识将更有可能发展。这些具体的知识最终有助于建立跨国公司的知识库。

Effects of Subcontracting on Firms in India's Informal Manufacturing Sector: An Empirical Investigation 转包对印度非正式制造业企业影响的实证研究

ABSTRACT: Subcontracting occurs when a producer outsources a part of its production. We study the effect of subcontracting from a firm with buyer power on the profits of subcontracted upstream firms, and how profits vary on the basis of location of firm and owner's gender. Subcontracting is the treatment in our study and the dependent variable is the ratio of Gross Value Added to Sales adjusted or unadjusted for wages. The decision of a firm to subcontract or not is endogenous, so we cannot use OLS regression. Since we cannot have information on a firm being treated and non-treated at the same time, we use the Average Treatment Effect on Treated (ATET) model with Nearest Neighborhood Matching (NNM) approach, in which each treated firm is matched to an untreated firm which is its nearest neighbor on other parameters, to see the effect of treatment on outcome variable on the treated group had they been not treated. We find the existence of a subcontracting premium where being in a subcontracting relationship is beneficial for the informal sector firm, though the magnitude of this premium is small, and female-headed firms gain less from subcontracting. Subcontracted male-owned firms earn a higher premium but also pay more wages out of their total revenue to labor as compared to female-owned firms, perhaps because the latter are more likely to be Own Account Manufacturing Enterprises (OAME) which do not employ hired workers. Our results show that buyer power of the subcontracting firms is offset by the benefits they provide to the subcontracted firms, possibly in the form of assured demand and payments. Thus, policies favoring the informal sector firms need to incorporate the benefits of subcontracting by exploring alternative modes of distribution with lower distribution margins, such as cooperative societies or online platforms for example Amul, MEESHO. Policies should also focus on reducing the profit margin differential between male and female owned firms by formulating a proper channel using mass media to communicate credit information and updates.
摘要:分包是指生产商将其部分生产外包出去。本文研究了具有买方权力的企业分包对上游分包企业利润的影响,以及利润如何根据企业所在地和所有者性别的不同而变化。分包是我们研究中的处理方法,因变量是调整或未调整工资的总增加值与销售额的比率。企业是否分包的决策是内生的,因此我们不能使用OLS回归。由于我们无法同时获得接受治疗和未接受治疗的公司的信息,因此我们使用了具有最近邻匹配(NNM)方法的平均治疗效果(ATET)模型,其中每个接受治疗的公司与未接受治疗的公司进行匹配,后者在其他参数上是其最近邻,以查看治疗对未接受治疗组的结果变量的影响。我们发现存在分包溢价,处于分包关系中对非正式部门公司有利,尽管这种溢价的幅度很小,并且女性领导的公司从分包中获得的收益较少。与女性拥有的公司相比,分包的男性拥有的公司获得更高的溢价,但也从其总收入中支付更多的工资给劳动力,这可能是因为后者更有可能是自营制造企业(OAME),不雇用雇佣工人。我们的研究结果表明,分包公司的买方权力被他们提供给分包公司的利益所抵消,这些利益可能以保证需求和支付的形式出现。因此,有利于非正规部门公司的政策需要通过探索分销利润较低的其他分销模式,如合作社或在线平台(如Amul、MEESHO),将分包的好处纳入其中。政策还应侧重于制订利用大众传播媒介传播信贷信息和最新情况的适当渠道,以缩小男女所有公司之间的利润差距。

Public vs. Private Education and the Labor Market Disparities in Nepal: Evience From the Blinder-Oaxaca Decomposition 尼泊尔公立与私立教育与劳动力市场差异:来自布林德-瓦哈卡分解的证据

ABSTRACT: The debate between private and public education is a widely discussed issue in personal and policy forums globally. In Nepal, private schools have grown significantly due to the perceived advantages associated with them. This paper tests if there are significant differences in labor-market outcomes for individuals educated in private schools compared to those educated in public schools. Research Methodology and Data: We employ nationally representative household survey data from the Nepal Living Standards Survey (NLSS III), conducted by the Central Bureau of Statistics (CBS) Nepal in 2010/11, utilizing the Living Standards Measurement Survey (LMSS) methodology developed by the World Bank. We apply the Blinder-Oaxaca decomposition method to examine the relationship between educational attainment and four distinct measures of labor-market outcomes: labor force participation, employment status, job security, and wage income. Initially, we estimate these outcomes separately for individuals in private education and those in public education. Subsequently, we calculate and analyze whether the disparities in estimated values can be attributed to differences in education. Our findings reveal significant labor-market disparities between individuals participating in private education and those in public education. Those with private education display lower rates of labor force participation and reduced employment rates, suggesting fewer working hours. However, those employed within this group enjoy more secure salaried positions. Furthermore, private education is linked to higher wage incomes, primarily attributable to longer educational periods. The Blinder-Oaxaca decomposition demonstrates that most of these disparities are associated with variations in educational backgrounds. Consequently, the results highlight the role of segregated education in contributing to labor-market inequality, emphasizing the impact of private schools in exacerbating economic disparities in Nepal. The findings underscore the significance of educational attainment in ameliorating disparities between individuals educated in public and private schools. To address these issues, policymakers should concentrate on strategies aimed at increasing the duration of education for public school students, such as providing free, quality higher education. By narrowing the educational gap between private and public institutions, the nation can work towards diminishing wage and job security disparities, fostering a more equitable society. These findings also have relevance for countries grappling with similar socio-economic challenges, initiating essential policy discussions.
摘要:私立教育与公立教育之争是一个在全球个人和政策论坛上被广泛讨论的问题。在尼泊尔,私立学校发展迅速,因为人们认为私立学校具有优势。本文检验私立学校和公立学校教育的个体在劳动力市场结果上是否存在显著差异。研究方法和数据:我们采用尼泊尔中央统计局(CBS)于2010/11年开展的尼泊尔生活水平调查(NLSS III)中具有全国代表性的家庭调查数据,采用世界银行开发的生活水平测量调查(LMSS)方法。我们应用Blinder-Oaxaca分解方法来检验教育程度与劳动力市场结果的四个不同衡量指标之间的关系:劳动力参与、就业状况、工作保障和工资收入。最初,我们分别对私立教育和公立教育的个体进行了这些结果的估计。随后,我们计算并分析了估计值的差异是否可以归因于教育的差异。我们的研究结果显示,参加私立教育和参加公立教育的个人之间存在显著的劳动力市场差异。接受课外教育的人的劳动参与率更低,就业率也更低,这意味着工作时间更短。然而,在这一群体中工作的人享有更稳定的领薪职位。此外,私立教育与较高的工资收入有关,这主要归因于较长的教育时间。布林德-瓦哈卡的分解表明,这些差异大多与教育背景的差异有关。因此,研究结果强调了隔离教育在促进劳动力市场不平等方面的作用,强调了私立学校在加剧尼泊尔经济差距方面的影响。研究结果强调了教育程度在改善公立学校和私立学校教育的个体之间的差异方面的重要性。为了解决这些问题,政策制定者应该把重点放在旨在增加公立学校学生受教育时间的战略上,比如提供免费、高质量的高等教育。通过缩小私立和公立学校之间的教育差距,国家可以努力缩小工资和工作保障的差距,建立一个更加公平的社会。这些发现对面临类似社会经济挑战、启动必要政策讨论的国家也具有重要意义。

ABSTRACT: Medical tourism is considered nowadays as a multi-billion industry which can promote a country's economic growth. Therefore, forecasting the scheduled tourism demand for medical services is of great importance for policy makers. Doing so, however, is not an easy task due to the following reasons: Data on medical tourism are (i) not easily accessible; (ii) not typically distinguished from tourists' non-scheduled (unintentional) use of a country's medical services; and (iii) usually not publicly available for long time periods. In this paper, we present a novel way to forecast tourism demand (intentional and unintentional) foro medical services —a rough but informative proxy of medical tourism— using limited data. To perform the analysis, we use data on the percentage of hospital discharges of non-residents for 17 European countries over the period 2008-2019 retrieved from Eurostat. Our methodological approach is based on a forecasting technique recently developed by Kyriazi, Thomakos and Guerard ; the adaptive learning forecasting. According to this method, MSE (Mean Squared Error)-performance enhancements can be achieved using any forecast as input —as long as that input is not a 'perfect' forecast— by learning from past forecast errors. Within this context, even the most basic forecast, the no-change or naïve forecast, can be used as input to the adaptive learning procedure. Kyriazi, Thomakos and Guerard approach is very well suited to our research question because (i) the no-change forecast is a natural candidate in a short time series where models cannot be estimated with sufficient accuracy, (ii) the no-change forecast is obviously far from being the 'perfect' forecast, and (iii) the adaptive learning process can be initialized by the no-change forecast and then learn by its own past forecast errors. Our results show that adaptive learning forecasting leads to performance enhancements that range from the 5% to more than 20% relative to the no-change benchmark. This finding indicates the efficiency of the adaptive learning method in forecasting medical tourism demand; an important subcategory of tourism demand for which data are not easily accessible and freely available historical data are existing for short time periods.
摘要:医疗旅游被认为是一个数十亿美元的产业,可以促进一个国家的经济增长。因此,预测定期旅游医疗服务需求对政策制定者具有重要意义。然而,这样做并非易事,原因如下:医疗旅游的数据(i)不易获得;(二)通常不能与游客非预定(无意)使用一国医疗服务区分开来;(iii)通常在很长一段时间内无法公开获取。在本文中,我们提出了一种新的方法来预测旅游需求(有意和无意)的医疗服务-一个粗略但信息丰富的代理医疗旅游-使用有限的数据。为了进行分析,我们使用了从欧盟统计局检索的2008-2019年期间17个欧洲国家的非居民出院百分比数据。我们的方法是基于Kyriazi, Thomakos和Guerard最近开发的预测技术;自适应学习预测。根据这种方法,MSE(均方误差)-性能增强可以使用任何预测作为输入-只要该输入不是“完美”的预测-通过学习过去的预测误差。在这种情况下,即使是最基本的预测,无变化或naïve预测,也可以用作自适应学习过程的输入。Kyriazi, Thomakos和Guerard方法非常适合我们的研究问题,因为(i)无变化预测是短时间序列中模型无法以足够的精度估计的自然候选,(ii)无变化预测显然远非“完美”预测,(iii)自适应学习过程可以由无变化预测初始化,然后通过自己过去的预测误差进行学习。我们的研究结果表明,相对于不变基准,自适应学习预测导致的性能增强范围从5%到20%以上。这一发现表明了自适应学习方法在医疗旅游需求预测中的有效性;这是旅游需求的一个重要子类,其数据不容易获得,但短期内可免费获得历史数据。

Predicting Corporate Bankruptcy in JSE-AltX Listed Firms JSE-AltX上市公司破产预测
Pub Date : 2023-06-01 DOI: 10.1353/jda.2023.a907733

ABSTRACT: The objective of the study is to predict corporate bankruptcy on the JSE-AltX (Alternative Stock Exchange) listed firms by employing Discriminant Analysis (MDA). Since its inception, the JSE-AltX has listed more than 100 firms and majority of them have migrated to the JSE main board. Motivated by the increasing number of delisted firms both pre and post their migration from JSE-AltX to the JSE main board, this study seeks to investigate the financial distress in the JSE-AltX listed firms. This study use a quantitative method to predict bankruptcy for a sample of 20 JSE-AltX listed firms that belongs to a wide range of industries, over the period from 1 January 2004 until 31 December 2015. Based on the previous literature it is evident that financial ratios play a significant role in the prediction of financial distress. Employing the same set of financial ratios (extracted from annual reports mainly the audited consolidated balance sheets and income statements) that are used in bankruptcy prediction as independent variables, the empirical results show that MDA has a statistically significant power in predicting default risk on the JSE-AltX listed firms. The findings show that the discrimination function is significant at the 5% level of significance. The MDA results reveal that, 7 out of the 20 sample firms are prone to bankruptcy, while the rest are not. Furthermore, the model classifies net profit margin (short-term profitability), current ratio (liquidity) and return on capital invested as the most important financial ratios in distinguishing the successful firms from unsuccessful firms post migration from the JSE-AltX to the JSE main board. Generally, this study results have policy implications which regulatory authorities, investors, employees and lenders will find interesting. Firstly, regulatory authorities can find this research useful as it provides effective review of the firm's financial distress conditions and subsequently signals default risk to various stakeholders. Secondly, this research will not only assist in identify potential default risks, but it will also enable different stakeholders to formulate mechanisms or relevant policies and procedures that will allow them to detect and prevent financial distress.
摘要:本研究旨在运用判别分析(MDA)对日本另类证券交易所(JSE-AltX)上市公司进行破产预测。自成立以来,JSE- altx已上市100多家公司,其中大多数已迁移到JSE主板。由于越来越多的退市公司从JSE- altx迁移到JSE主板之前和之后,本研究旨在调查JSE- altx上市公司的财务困境。本研究采用定量方法对2004年1月1日至2015年12月31日期间20家JSE-AltX上市公司的破产进行预测,这些公司属于广泛的行业。根据以往的文献,很明显,财务比率在财务困境的预测中起着重要的作用。采用破产预测中使用的同一组财务比率(主要是从年度报告中提取的经审计的合并资产负债表和损益表)作为自变量,实证结果表明,MDA对JSE-AltX上市公司的违约风险预测具有统计学显著的能力。结果表明,在5%显著性水平下,判别函数显著。MDA分析结果显示,20家样本企业中有7家有破产倾向,其余企业没有破产倾向。此外,该模型将净利润率(短期盈利能力),流动比率(流动性)和资本投资回报率分类为区分成功公司和不成功公司从JSE- altx迁移到JSE主板后最重要的财务比率。一般来说,这项研究的结果具有政策意义,监管当局,投资者,员工和贷款人会发现有趣的。首先,监管当局会发现这项研究很有用,因为它提供了对公司财务困境状况的有效审查,并随后向各利益相关者发出违约风险信号。其次,这项研究不仅有助于识别潜在的违约风险,而且还将使不同的利益相关者制定机制或相关政策和程序,使他们能够发现和防止财务困境。

Based on the previous literature it is evident that financial ratios play a significant role in the prediction of financial distress. Employing the same set of financial ratios (extracted from annual reports mainly the audited consolidated balance sheets and income statements) that are used in bankruptcy prediction as independent variables, the empirical results show that MDA has a statistically significant power in predicting default risk on the JSE-AltX listed firms. The findings show that the discrimination function is significant at the 5% level of significance. The MDA results reveal that, 7 out of the 20 sample firms are prone to bankruptcy, while the rest are not. Furthermore, the model classifies net profit margin (short-term profitability), current ratio (liquidity) and return on capital invested as the most important financial ratios in distinguishing the successful firms from unsuccessful firms post migration from the JSE-AltX to the JSE main board. Generally, this study results have policy implications which regulatory authorities, investors, employees and lenders will find interesting. Firstly, regulatory authorities can find this research useful as it provides effective review of the firm's financial distress conditions and subsequently signals default risk to various stakeholders. Secondly, this research will not only assist in identify potential default risks, but it will also enable different stakeholders to formulate mechanisms or relevant policies and procedures that will allow them to detect and prevent financial distress.","PeriodicalId":84983,"journal":{"name":"Journal Of Developing Areas","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135144590","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}
