Abstract The significance of a study of political incumbency and the factors influencing it stems from the fact that it directly affects the behaviour of the incumbent political party and its accountability to the electorate. We use data on Parliamentary Elections in India from 1980 to 2014 to tease out evidence of incumbency advantage. We employ Regression Discontinuity Design (RDD) to estimate the incumbency effect. Our results indicate the absence of any incumbency effect when considering all elections in India together. This finding is at odds with the research reported so far. To explain our contrary result, we drilled down deeper to obtain a more granular view of the incumbency effect in India. We do this across various regions of India. The results show that north Indian states generally show strong evidence of incumbency disadvantage while south Indian states show strong evidence of incumbency advantage. We also show that incumbency advantage has increased over time
摘要研究政治现任及其影响因素的意义在于,它直接影响现任政党的行为及其对选民的责任。我们使用1980年至2014年印度议会选举的数据来梳理在职优势的证据。我们采用回归不连续性设计(RDD)来估计在职效应。我们的结果表明,在一起考虑印度的所有选举时,没有任何现任效应。这一发现与迄今为止报道的研究结果不一致。为了解释我们的相反结果,我们深入研究,以获得对印度在职效应的更精细的看法。我们在印度的各个地区都这样做。结果表明,北印度各州普遍表现出在职劣势的有力证据,而南印度各州则表现出在职优势的有力证据。我们还表明,在职优势随着时间的推移而增加

Abstract Different regions are linked through different factors such as climate, and border sharing. Apart from this, African countries have developed significant links as a result of globalisation, economic integration, and trade liberalisation. Since any country’s economic growth is influenced by the performance of its neighbours, these ties have resulted in spatial dependence among these countries. On this basis, the significance of spatial interactions between countries cannot be overemphasised. It is for this reason that the study investigated spatial dependence between African countries. The study employed non-spatial (FE, GMM) and spatial (SDM, SAM, and SEM) econometrics techniques and data ranging from 1996 to 2019 to examine the impact of ODA on Economic growth in Africa and its spill-over effects. Based on the graphs and the Moran I test, the findings reveal that (i) there is spatial dependence among African countries (ii) The GMM results indicate that the ODA impact was positive and statistically significant but smaller in magnitude compared to the magnitude of the spatial models’ coefficients. This suggests that not controlling for space heterogeneity will possibly underestimate the real impact of ODA on GDP. Secondly, the study found that the weighted GDP was positive and statistically significant, which indicates that an increase in the GDP of a certain country has a positive and statistically significant impact on their neighbour’s economic growth. Based on the findings of the study, it is suggested that countries should improve their relationships and partnerships if they want ODA to provide the desired benefits across Africa.
不同的区域通过气候、边界共享等不同的因素联系在一起。除此之外,由于全球化、经济一体化和贸易自由化,非洲国家发展了重要的联系。由于任何国家的经济增长都受到其邻国经济表现的影响,这些联系导致了这些国家之间的空间依赖。在此基础上,国家间空间互动的重要性怎么强调都不为过。正是出于这个原因,本研究调查了非洲国家之间的空间依赖关系。该研究采用非空间(FE、GMM)和空间(SDM、SAM和SEM)计量经济学技术和1996年至2019年的数据,考察了官方发展援助对非洲经济增长的影响及其溢出效应。基于图形和Moran I检验,研究结果表明:(1)非洲国家之间存在空间依赖性;(2)GMM结果表明,官方发展援助的影响是正的,具有统计学意义,但与空间模型系数的大小相比,其幅度较小。这表明,不控制空间异质性可能会低估官方发展援助对GDP的实际影响。其次,研究发现,加权GDP为正且具有统计学意义,这表明一国GDP的增长对其邻国的经济增长具有正且统计学意义显著的影响。根据这项研究的结果,建议各国如果希望官方发展援助在整个非洲提供所需的利益,就应该改善它们的关系和伙伴关系。

Abstract Female participation on corporate board is one of the most studied topics in corporate governance research. This paper analyzes the effect of female directors and gender diversity on bid ask spread. We calculate the score of female governance and we test three proxies of a bid-ask spread. Our results provide comprehensive and robust evidence for the association between female board participation and stock liquidity in Tunisian market. This study is based on a sample covering all financial firms in Tunisia (banks, insurances, and leasing) from 2008 to 2019 based on panel data approach. We conclude that female directors generate a positive effect on stock liquidity when they have a more active role on the board and when they are represented in relatively large numbers. Female CEO and institutional female directors enhance monitoring quality, develop control and improve supervising. Female directors are more effective at changing board processes, improving governance, and then affect significantly and negatively bid ask spread. Our research is the first to use the female governance index, it proves that female directors improve corporate governance, enhance stock liquidity. This result encourages firms to select competitive women to occupy strategic posts.
女性董事参与是公司治理研究中研究最多的课题之一。本文分析了女性董事和性别多样性对投标价差的影响。我们计算了女性治理的得分,并测试了买卖价差的三个代理。我们的研究结果为突尼斯市场女性董事会参与与股票流动性之间的关系提供了全面而有力的证据。本研究基于2008年至2019年突尼斯所有金融公司(银行、保险和租赁)的样本,采用面板数据法。我们的结论是,当女性董事在董事会中扮演更积极的角色时,当她们的代表人数相对较多时,女性董事对股票流动性产生了积极的影响。女性CEO和机构女性董事提高监督质量,发展控制,完善监督。女性董事在改变董事会流程、改善治理方面更有效,从而对出价价差产生显著的负面影响。本研究首次运用女性治理指数,证明女性董事改善公司治理,增强股票流动性。这一结果鼓励公司选择有竞争力的女性担任战略职位。

Rethinking export diversification to stimulate resilience against future economic shocks in Sub-Saharan Africa 重新思考出口多样化,以增强撒哈拉以南非洲应对未来经济冲击的能力

Abstract The literature suggests that export diversification is growth-inducing, particularly in developing countries. However, Sub-Saharan Africa has been experiencing deteriorating or insignificant economic growth levels. The region’s exports are highly concentrated; thus, this paper sought to examine the extent of export diversification and its effect on economic growth in Sub-Saharan Africa (SSA). Further, the paper assessed the presence of a U-shaped hypothesis in the context of SSA. The GMM approximation technique was adopted to examine the model’s relationship and control for endogeneity. The results suggest that export concentration significantly hampers economic growth. The results further indicated that foreign direct investment, domestic investment, and trade openness stimulate growth – while weak governance, fluctuating exchange rates and trade policy also adversely affect economic growth. However, the results do not support a hump-shaped (non-linear) correlation between export diversification and economic growth in SSA. To fully recover from the global pandemic and attain higher levels of economic growth, the Sub-Saharan African region needs to implement policies that allow export products and market diversification. While diversification is crucial for development, improving the quality of governance should also be a prerequisite, given that weak governance may interfere with ratifying appropriate and relevant policies aimed at facilitating export diversification.
文献表明,出口多样化是促进增长的,特别是在发展中国家。然而,撒哈拉以南非洲的经济增长水平一直在恶化或微不足道。该地区的出口高度集中;因此,本文试图考察出口多样化的程度及其对撒哈拉以南非洲(SSA)经济增长的影响。进一步,本文评估了在SSA背景下u形假设的存在。采用GMM逼近技术检验模型的关系和内生性控制。结果表明,出口集中度显著阻碍经济增长。结果进一步表明,外国直接投资、国内投资和贸易开放刺激增长,而治理不力、汇率波动和贸易政策也对经济增长产生不利影响。然而,结果并不支持出口多样化与SSA经济增长之间的驼峰形(非线性)相关性。为了从全球大流行病中完全恢复并实现更高水平的经济增长,撒哈拉以南非洲区域需要执行允许出口产品和市场多样化的政策。虽然多样化对发展至关重要,但提高管理的质量也应是一个先决条件,因为管理薄弱可能妨碍批准旨在促进出口多样化的适当和相关政策。

Abstract Taxation has been recognised as a proactive tool for achieving fiscal capacity, yet irreconcilable views exist as to why, decades after independence, countries in Africa still face challenges financing their public spending needs. One of the factors that has been studied in recent years is the performance of the institutions responsible for revenue mobilisation. Countries need effective, efficient, and capable tax authorities to mobilise sufficient revenue. This paper uses data from 27 African countries collected by African Tax Administration Forum (ATAF), to assess the efficiency of African tax administrations. It applies parametric (stochastic frontier) and non-parametric (data envelopment) techniques to generate efficiency scores and rank tax administrations. The results suggest that many African tax administrations operate inefficiently and could improve their performance by between 3 and 79% to reach their maximum capacity. Applying the Tobit regression technique shows that the granting of partial autonomy to revenue collection agencies, the size of the informal sector, size of non-tax revenue, and segmentation of taxpayers have significant effects on the efficiency of tax administrations. The paper highlights the importance of determining the level of efficiency and the factors that matter for improving the performance of revenue authorities and building fiscal capacity.
税收被认为是实现财政能力的一种积极的工具,然而,在独立几十年后,非洲国家仍然面临为其公共支出需求融资的挑战,存在着不可调和的观点。近年来研究的一个因素是负责收入调动的机构的绩效。各国需要有效、高效和有能力的税务机关来调动足够的收入。本文利用非洲税收征管论坛(ATAF)收集的27个非洲国家的数据来评估非洲税收征管的效率。它应用参数(随机前沿)和非参数(数据包络)技术来生成效率分数和排名税收管理。结果表明,许多非洲税务管理部门的运作效率低下,可以将其绩效提高3%至79%,以达到其最大能力。运用Tobit回归技术表明,税收征管机构的部分自治权、非正规部门的规模、非税收入的规模和纳税人的细分对税收征管效率有显著影响。本文强调了确定效率水平的重要性,以及提高税收当局绩效和建设财政能力的重要因素。

Abstract This study utilises a dynamic panel data method to identify the short-run and long-run effects of host countries’ economic freedom on international tourism, focussing on the least developed countries (LDCs). Based on the panel data of 154 countries from 2002 to 2019, we find that the three broad aspects of economic freedom—property rights enforcement, regulatory efficiency, and market openness—have differential impacts on the LDCs and their more developed counterpart. LDCs are more responsive to an improvement in regulatory efficiency. Specifically, a more efficient labour market and stable price level in the host country attracts more inbound tourism. Tourism in developed countries, in contrast, is more responsive to an improvement in property rights enforcement. As such, we recommend countries consider their development status as they promote tourism.
摘要本研究利用动态面板数据方法来确定东道国经济自由对国际旅游业的短期和长期影响,重点关注最不发达国家。基于2002年至2019年154个国家的面板数据,我们发现经济自由的三个广泛方面——产权执行、监管效率和市场开放——对最不发达国家和较发达国家产生了不同的影响。最不发达国家对监管效率的提高反应更为积极。具体而言,东道国更有效的劳动力市场和稳定的价格水平吸引了更多的入境旅游。相比之下,发达国家的旅游业对产权执行的改善反应更大。因此,我们建议各国在促进旅游业时考虑其发展状况。

Abstract This study develops a macro-econometric model for a typical supply constrained African economy aimed at developing a theoretical and empirical template for such policy tools that are increasingly being demanded by African ministries of finance and central banks. We concretised it by building a macro-econometric model for Rwanda. The model is designed to capture the structural characteristics of such an African economy. The Rwanda macro-econometric model has 107 equations of which 72 are endogenous. In addition, we also build a supplementary ARIMA based model with 33 equations for the exogenous variables to make the model useful for forecasting. We disaggregate the fiscal, balance of payments and money supply blocks of the model to offer an adequate picture of the macro-economy. We also do an econometric estimation of the core behavioural equations of the model using the error correction modelling approach for the period 1960–2009. The model can be easily extended further to support the budgeting, forecasting and macroeconomic policy analyses in the relevant ministries and central banks in Africa. We successfully solve the model and reproduce historical values from 1999 to 2009 and forecast major macro-variables for 2010 to 2015. We also use the model to conduct policy and external shock simulation exercise that are important for policymakers.
摘要本研究为一个典型的供应受限的非洲经济开发了一个宏观计量经济模型,旨在为非洲财政部和中央银行日益要求的此类政策工具开发一个理论和实证模板。我们通过为卢旺达建立宏观经济计量模型,将其具体化。该模型旨在捕捉这样一个非洲经济体的结构特征。卢旺达宏观经济计量模型有107个方程,其中72个是内生方程。此外,我们还建立了一个基于ARIMA的补充模型,其中包含33个外生变量方程,使该模型对预测有用。我们对该模型的财政、国际收支和货币供应块进行了分解,以提供对宏观经济的充分了解。我们还使用1960-2009年期间的误差校正建模方法对模型的核心行为方程进行了计量经济学估计。该模型可以很容易地进一步扩展,以支持非洲相关部委和中央银行的预算编制、预测和宏观经济政策分析。我们成功地求解了该模型,重现了1999年至2009年的历史值,并预测了2010年至2015年的主要宏观变量。我们还使用该模型进行政策和外部冲击模拟练习,这对决策者很重要。

The influence of different financial market regimes on the dynamic estimation of GARCH volatility model parameters and volatility forecasting 不同金融市场制度对GARCH波动率模型参数动态估计及波动率预测的影响
Q4 Economics, Econometrics and Finance Pub Date : 2022-07-03 DOI: 10.1080/03796205.2022.2143881

Abstract Volatility is one of the measures of risk within the financial markets. GARCH modelling involves important volatility forecasting methodology and is widely used in finance. It is important to be able to forecast volatility since volatility has an impact on financial portfolios and the risk hedging methodology followed by financial companies. This study investigates the behaviour of parameter estimates and volatility forecasts of GARCH models over time, using a rolling window estimation procedure. Three GARCH models, the Symmetric GARCH, GJR-GARCH and E-GARCH models, are compared. The dataset used in the study comprises of the JSE All-Share index. This index is divided into two different periods, namely, a tranquil financial period and a turbulent financial period. Different factors influence the performance of GARCH models and consequently determines which GARCH model is the most suited for certain circumstances. These factors are: the sample window period, forecasting horison, the financial period and the underlying distribution of the log returns.
波动性是衡量金融市场风险的指标之一。GARCH模型涉及重要的波动率预测方法,在金融领域得到广泛应用。能够预测波动性是很重要的,因为波动性对金融投资组合和金融公司所遵循的风险对冲方法有影响。本研究使用滚动窗口估计程序,研究了GARCH模型的参数估计和波动率预测随时间的行为。对对称GARCH、GJR-GARCH和E-GARCH三种GARCH模型进行了比较。研究中使用的数据集包括JSE全股票指数。该指标分为两个不同的时期,即平静的金融时期和动荡的金融时期。不同的因素影响GARCH模型的性能,从而决定了哪种GARCH模型最适合某些情况。这些因素是:样本窗口期、预测期、财务期和日志收益的潜在分布。

Abstract The paper aims to investigate the determinants of supply and demand-side factors of house price dynamics and their impact on household indebtedness in Namibia. An autoregressive distributed lag (ARDL) model was used. The findings support the hypothesis’ that supply-side and demand-side factors had a significant effect on house price as well as household indebtedness. It was found that money supply, working population, construction cost index, mortgage loans, previous quarter house prices, and current GDP were found to be the key determinants of both supply and demand-side factors of house-price dynamics in Namibia. Additionally, an increase in mortgage loans would increase household indebtedness in the short run and was found to be the key determinant of household indebtedness in Namibia. This indicates that an expansionary monetary policy could address the twin problem of rising house prices and household indebtedness. Policy implications derived from the study indicate that although monetary policy can be used to address the issues of escalating house prices and indebtedness, this policy intervention may be limited because Namibia does not have an autonomy regarding its monetary policy due to its currency board operations arrangement.
摘要本文旨在研究纳米比亚房价动态的供给侧和需求侧因素的决定因素及其对家庭负债的影响。采用自回归分布滞后(ARDL)模型。研究结果支持了“供给侧和需求侧因素对房价和家庭负债有显著影响”的假设。研究发现,货币供应量、工作人口、建筑成本指数、抵押贷款、上一季度房价和当前GDP是纳米比亚房价动态的供给侧和需求侧因素的关键决定因素。此外,抵押贷款的增加将在短期内增加家庭负债,并被认为是纳米比亚家庭负债的关键决定因素。这表明,扩张性货币政策可以解决房价上涨和家庭负债的双重问题。从这项研究得出的政策影响表明,虽然货币政策可以用来解决不断上升的房价和债务问题,但这种政策干预可能是有限的,因为纳米比亚由于其货币发行局业务安排,在货币政策方面没有自主权。

Abstract This study investigates the impact of exchange rate volatility on trade flows in Brazil, Russia, India, China and South Africa (BRICS), for the period 2009:M1 to 2019: M12. To capture the short- and long-term symmetric and asymmetric relationships, the linear and nonlinear autoregressive distributed lag (ARDL) models were employed. The findings indicate that rising exchange rate volatility is associated with growing trade flows in Russia and India while declining exchange rate volatility reduces Chinese imports. It is also revealed that rising and declining exchange rate volatility have opposite effect on trade flow in South Africa. Additionally, the result show evidence of both long run and short run asymmetric behaviour. Accordingly, this study recommends the adoption of flexible exchange rate policy among BRICS economies and that traders and businesses should take advantage of exchange rate volatility.
摘要本研究调查了2009年M1至2019年M12期间,汇率波动对巴西、俄罗斯、印度、中国和南非(金砖国家)贸易流动的影响。为了捕捉短期和长期的对称和非对称关系,采用了线性和非线性自回归分布滞后(ARDL)模型。研究结果表明,汇率波动性的上升与俄罗斯和印度贸易流量的增加有关,而汇率波动性下降则减少了中国的进口。研究还表明,汇率波动率的上升和下降对南非的贸易流动产生了相反的影响。此外,该结果还显示了长期和短期不对称行为的证据。因此,本研究建议金砖国家经济体采取灵活的汇率政策,贸易商和企业应利用汇率波动。
