Opis:
The present paper investigates African stock markets’ linkages by considering stocks in the continent’s largest economies, specifically Egypt, Kenya, Morocco, Nigeria, South Africa, and Tunisia. Using a dataset that spanned November 25, 2008, to September 18, 2023, the quantile connectedness approach of Chatziantoniou et al. (2021) is employed, and the results unfold these interesting dynamics of African market connectivity: (i) In the bearish market phase, South African stock dominated the entire network, transmitting shocks to the remaining stocks, while Moroccan and Kenyan stocks played similar role mildly. (ii) In the bullish market phase, Nigerian stock dominated the market as a major net transmitter of shock supported by South African and Kenyan stock markets. (iii), The Egyptian and Tunis stock markets are net shock receivers in both the bear and bull market phases. (iv), At the median quantile value, stocks become less riskier and the Kenyan stock market becomes the most vulnerable while Nigerian, Egyptian, and South African stock markets are influenced by other stock markets when markets are calm. (v), Though, African stocks are underperforming, interested portfolio managers will learn from the trading strategies to be adopted to maximize their returns. These findings will benefit portfolio managers, international stakeholders, and regulators.

Opis:
Research background: Corporate sustainable development (CSD) is essential to a company's success and survival. Environmental, social, and governance (ESG) are regarded as major factors in measuring the impact of CSD. Companies that perform well in terms of ESG can maintain a competitive advantage and achieve sustainable development. Poor management of ESG performance and involvement in controversial activity can harm a company's credibility and reputation in the market, as well as negatively impact sustainable development. Purpose of the article: Drawing on the stakeholder and signaling theories, this paper investigates the curvilinear nexus between ESG performance and CSD. Methods: Empirical studies were conducted on a sample of 697 Chinese listed manufacturing firms that disclosed ESG information from 2010 to 2020, with a total of 5699 firm-year observations. Quantile regression analysis and the U-test were used to examine the curvilinear ESG-CSD relationship. This technique was supplemented by conducting instrumental variables tests and propensity score matching to address concerns relating to the potential existence of endogeneity problems. Findings & value added: The results of the quantile regression estimation confirm the concave-convex (inverted U-shaped and U-shaped) ESG-CSD relationship via the U-test. The relationships between the environmental and social components and CSD follow an inverted U-shaped or half-inverted U-shaped pattern, while the relationship between the governance component and CSD exhibits a concave-convex pattern. A concave ESG-CSD nexus is evident in environmentally sensitive industries, whereas a half concave-convex ESG-CSD nexus is confirmed in non-environmentally sensitive industries. This study improves scholars’ understanding of ESG performance and provides a comprehensive perspective on the double-edged effects (positive and negative consequences) of ESG practices. The instrumentalization of ESG practices for management to seek personal gain has a negative impact on CSD, while ESG practices that add value for stakeholders have a positive impact. These findings provide empirical evidence for Chinese publicly listed manufacturing firms to effectively conduct ESG practices.

Opis:
This study aims to measure the impact of environmental regulation on the production of renewable energies in OECD countries from 1990 to 2021. Environmental policies stringency, environmental taxes, and CO2 emissions are variables indicating environmental regulation, which affect renewable energies production. The study relied on unconditional quantitative regression methods. The study found that strict environmental policies do not necessarily enhance renewable energy production in countries with high or low production. Moreover, environmental tax revenues have varying impacts on renewable energy production based on renewable energy production in each country. For countries with below-average levels of renewable energy (Q25), environmental taxes positively affect renewable energy production; however, in countries with high production levels (Q90), environmental taxes show a negative effect. Furthermore, CO2 emissions negatively affect the total production of renewable energy in all quantiles except Q50, whereas R&D spending positively affects renewable energies in all quantiles except Q75. The estimates also showed a significant negative effect of patents on the renewable energy production in quantile Q10. The results underscore the importance of flexibility and adaptability in environmental policies and taxes. Finally, the study indicates that policies must be dynamic and respond to the specificity of each stage of renewable energy development in the studied countries.

Opis:
Analiza popytu polega w głównej mierze na określeniu związków zachodzących między spożyciem a cenami dóbr oraz zmieniającymi się dochodami konsumentów. Nieco innym ujęciem badania determinant popytu jest próba wyjaśnienia zapotrzebowania na zróżnicowaną dietę, czyli poszukiwanie czynników mających statystycznie istotny wpływ na ilość i rozkład dóbr nabywanych przez konsumentów. Celem badania omawianego w artykule jest wyznaczenie czynników istotnie wpływających na zróżnicowanie diety w gospodarstwach domowych w Polsce. Wykorzystano nieidentyfikowalne dane jednostkowe pochodzące z badania budżetów gospodarstw domowych przeprowadzonego przez Główny Urząd Statystyczny w 2020 r. Na podstawie estymacji modelu regresji kwantylowej oszacowano wartości parametrów dla zmiennych objaśniających, które opisują badane gospodarstwa. Uzyskano rezultaty świadczące o tym, że poziom zróżnicowania diety w gospodarstwie domowym zależy zarówno od jego dochodu i wielkości, jak i od takich jego cech, jak: grupa społeczno-ekonomiczna, miejsce zamieszkania oraz wiek i wykształcenie głowy gospodarstwa domowego. Ponadto wskazano, że wpływ wymienionych czynników na badane zjawisko zależy od poziomu zróżnicowania diety. Dowiedziono również, że czynniki te mają większe znaczenie w przypadku gospodarstw domowych, które cechują się niewielkim popytem na zróżnicowaną dietę.
Demand analysis focuses mainly on the study of the relationship between consumption, prices of goods and the changing income of consumers. An attempt aiming to explain the demand for food diversity involves a slightly different approach to research on the determinants of demand. This approach searches for factors that have a statistically significant effect on the quantity and distribution of goods purchased by consumers. The aim of the study described in the article is to determine the factors that have a significant influence on the diversity of the diet in Polish households. The study uses non-identifiable microdata from the 2020 Household Budget Survey conducted by Statistics Poland. Based on the estimation of the quantile regression model, parameter estimates were obtained for the explanatory variables describing the surveyed households. The results confirm that, apart from income and household size, the level of the diversity of a diet depends on the following characteristics: the socio-economic status of the household, place of residence, and the age and education level of the head of the household. The study also shows that the effect of the analysed factors depends on the degree to which the diet is diverse. In general, the impact of the considered factors is more significant for households showing a low demand for a varied diet.

Opis:
Research background: Achieving a jointly stable and inclusive financial system represents an important pillar of the call for action among Sustainable Development Goals. Considerable attention from previous research has been given to traditional financial inclusion (FI) and its implications on financial stability and overall development, but the findings are mixed. Furthermore, there is limited evidence related to the implications of digital financial inclusion on banking system stability. Therefore, the present study tends to address two main research questions, as follows: Can traditional financial inclusion protect banking stability? Can digital finance inclusion become a new driving force to promote banking stability? Purpose of the article: The paper aims to assess the influence of both traditional and digital financial inclusiveness on banking stability, using quantile regression, across a panel of 81 countries. We also examine the potential transmission channels through which financial inclusiveness influences banking stability. Methods: We construct three different financial inclusion indices, which capture the degree of access and usage of financial services, based on a three-stage Principal Component Analysis. Next, based on quantile analysis, we test the role of these financial inclusion indices in shaping banking stability. Findings & value added: We provide international evidence on the non-linear relationship between traditional and digital FI and banking stability, respectively. Our empirical findings suggest that FI indices are negatively related to banking stability until a certain threshold, after which, increases in financial inclusiveness have a positive effect on banking stability. The magnitude of the impact is more sizeable for low-range quantiles, meaning that the effect of digital inclusiveness is more pronounced in countries with excessive risk-taking tendencies. We find support for operational efficiency transmission channels and uncover new evidence on the association between digital FI and banking stability.

Opis:
Product reliability design optimization is affected by epistemic uncertainty greatly, which leaves significant risks in product use. In this paper, a new belief reliability-based design optimization (BRBDO) method under epistemic uncertainty is established to handle this problem. First, the belief reliability theory is introduced into the design optimization problem, and a quantile index is proposed to quantify belief reliability level based on uncertainty theory, through which a rapid analysis method called first order belief reliability analysis (FOBRA) method is developed. Then, according to the different trade-off strategies, two types of design optimization models are established, and corresponding FOBRA-based computation methods are also demonstrated. Finally, several case applications are studied to verify the effectiveness of the analysis and design optimization methods proposed in this paper. The results indicate that the BRODO method with the quantile index can save a lot of computational time with acceptable accuracy and can rationally cope with epistemic uncertainty.

We examine the impact of COVID-19 on the banking and fintech sectors based on the relationships of the respective stock indices from December 2017 to April 2022. We analyse dynamic correlations within multivariate GARCH models and relationships in tails with the quantile coherency approach. Returns of fintech and banks dropped simultaneously at the beginning of the pandemic, but the analysis of cumulative returns and draw-downs reveals that the former recovered faster. Banks and fintechs experienced sharp declines together and fintech experienced extreme growth during the downfalls in the banking sector. However, the latter relationship disappears when we analyze only the banks from the USA and Eurozone. Thus, integrating with fintech may be especially beneficial for banks outside those regions. The ability of fintech to resurface and continue to grow demonstrates its importance in the financial system and confirms the shift toward a digital economy in financial markets.

Opis:
The purpose of this paper is to investigate the correlation between female entrepreneurship and happiness within the Association of Southeast Asian Nations (ASEAN) region. The study uses a panel data model with two independent variables measuring female entrepreneurship and five control variables measuring the determinants of happiness. The method used for analysis is the panel fixed effects of the method of moments quantile regression (MM-QR) to examine data from nine ASEAN countries between 2006 and 2021. MM-QR can capture the location and scale of the conditional distribution of the dependent variable, making it suitable for studying the heterogeneous effects of female entrepreneurship on happiness across happiness quantiles. This approach controls for unobserved time-invariant heterogeneity, reducing omitted variable bias in cross-sectional studies. The MM-QR approach is rigorous and robust for analysing the complex relationship between female entrepreneurship and happiness in ASEAN countries. The main contribution of this study is to shed light on the relationship between female entrepreneurship and happiness, which reinforces and supports comprehensive development in emerging countries. The findings suggest that policymakers and practitioners can benefit from supporting female entrepreneurship by implementing policies and programs that provide access to education, training, mentorship, and financing. Furthermore, the study highlights the importance of the gender development index (GDI) as a determinant of happiness in ASEAN countries.

Research background: Corporate risk-taking (CRT) is crucial to a business's survival and performance and is a driving force for sustainable development. Environmental, social and governance (ESG) practices are critical to firm profits when considering sustainable economic growth; however, they can also be the cause of financial burdens. It is, therefore, crucial to assess the relationship between a company's ESG performance and its risk-taking. Purpose of the article: Considering the controversial results of empirical studies on the relationship between ESG and CRT, this study aims to theoretically and empirically investigate the curvilinear nexus between ESG practices and CRT within Taiwan's high-tech industry. Methods: Ordinary least square regression and quantile regression analysis was applied to investigate the curvilinear ESG-CRT relationship. The empirical studies were conducted in 38 high-tech companies on the Taiwan Stock Exchange that disclosed ESG information between 2005 and 2020, with a total of 437 firm-year observations. Findings & value added: Quantile regression estimation results reveal the ESG-CRT nexus is U-shaped (convex). Both the environmental and social pillar's relationship with CRT is nonlinear and U-shaped, whereas the governance pillar has no significant relationship with CRT. Overall, a comprehensive view is provided that shows ESG practices can have a double-edged sword effect on CRT. It is suggested that high-tech companies in Taiwan should avoid ESG practices becoming a tool for managements' self-interest. More information of ESG practices should be disclosed to stakeholders to ensure they are given full credit for the positive impact they have on capital allocation. Regulators guide firms to surpass the threshold of the U-shaped effect and take into consideration the whole benefits of stakeholders when they allocate existing resources toward environmental and social endeavors.

Research background: According to classical labor economics, wage differences among regions of a country that has free-factor mobility should eventually vanish. However, the level of wage inequality among Mexican territories is increasing. The nature and causes of this discrepancy are worth identifying. Purpose of the article: To identify the spatial relationship of wage inequality that existed in the Mexican metropolitan system during the years 2010 and 2015. Methods: We develop a model of wages that considers the interaction between spatial units within a region. Then, we specify a spatial autoregressive model with the average wage per municipality as a dependent variable. This variable is spatially lagged along with other controls such as productivity, schooling, and migration. We combine data from population and economic censuses. Then, we perform a quantile regression to estimate the spatial effect of wage in a region upon quartiles of the wage distribution. Findings & value added: Wage inequality increases within a given region when the average wage increases in one of said region?s municipalities. This phenomenon occurs because in municipalities that are neighbors of the one that enjoys a wage increase, the average wage tends to decrease. The impact is larger in those municipalities whose average wage is in the lower range of the regional wage distribution. Wage inequality is also increased by internal migration and increased productivity. These latter findings are some of the first for Mexico at this aggregation level. A novel aspect of our study is its use of territory as an observation unit for which statistics from population and economic censuses are combined to draw inferences about spatial inequality.

Opis:
Managing the exploitation of technical equipment under conditions of uncertainty requires the use of probabilistic prediction models in the form of probability distributions of the lifetime of these objects. The parameters of these distributions are estimated with the use of statistical methods based on historical data about actual realizations of the lifetime of examined objects. However, when completely new solutions are introduced into service, such data are not available and the only possible method for the initial assessment of the expected lifetime of technical objects is expert methods. The aim of the study is to present a method for estimating the probability distribution of the lifetime for new technical facilities based on expert assessments of three parameters characterizing the expected lifetime of these objects. The method is based on a subjective Bayesian approach to the problem of randomness and integrated with models of classical probability theory. Due to its wide application in the field of maintenance of machinery and technical equipment, a Weibull model is proposed, and its possible practical applications are shown. A new method of expert elicitation of probabilities for any continuous random variable is developed. A general procedure for the application of this method is proposed and the individual steps of its implementation are discussed, as well as the mathematical models necessary for the estimation of the parameters of the probability distribution are presented. A practical example of the application of the developed method on specific numerical values is also presented.

Opis:
Soil and water conservation (SWC) technologies contribute to sustainable agriculture and rural poverty reduction. Yet, the relationship between farm household income and SWC investment is not well-understood in Rwanda. This study aims to assess the effects of investing in SWC on household income and improve the knowledge of how various classes of smallholders can benefit from such an investment at a farm level. The study used survey data from 422 farming households in northern Rwanda’s Burera, Gakenke and Musanze districts. Descriptive analysis was employed to determine levels of use of SWC and SF measures. Quantile estimation classified three classes of farming households: the poor, middle-income earners and the rich. Instrumental variable quantile regression was adopted to assess heterogeneous effects of financing SWC investment. The results revealed that the extent of using SWC and SF measures is generally low. Agriculture income and off-farm (casual) wages had the largest income shares among the poor and middle-income earners. Financing investment in SWC increases income significantly for middle-income earners, i.e. five times more than the poor, but it was ineffective for the wealthy. Socio-economic factors and commercial crops had a significant effect on income across the classes. Institutional factors demonstrated no significant impact on the poor and middle-income earners. The findings suggest that incorporating pro-poor interventions in SWC investment would increase the productivity and commercialisation of cash and staple crops. These results inform a need to promote linkages between SWC investment and income diversification strategies to increase asset-building for the poor and close income gaps among the three farming classes. This finding suggests the need to introduce saving and lending innovations in SWC that link farm activities to nonfarm opportunities.
