The study tests hypotheses about the processing mechanism (moral identity) and the boundary condition (proactive personality) to understand these relationships.Design/methodology/approachThe study collected time-lagged survey data through an online structured questionnaire from 182 respondents. Confirmatory factor analysis (CFA) was used to ensure the validity and reliability of the data. Moreover, structural equation modeling was run to test the hypotheses using AMOS.FindingsEthical leadership positively affects followers' promotive and prohibitive voice behavior via the psychological mechanism of moral identity. Proactive personality moderates the moral identity – promotive and moral identity – prohibitive voice relationships, such that these relations are stronger when the individuals are high on proactive personality.Research limitations/implicationsRobust evidence of a genuine cause-and-effect relationship may not be yielded owing to cross-sectional and self-reported data at the follower level of analysis. Future researchers can use dyadic, longitudinal and experimental designs to overcome these limitations. Organizations targeting to increase voice behavior can benefit from maintaining ethical leaders and proactive followers at the workplace.Originality/valueThe study significantly contributes to the ethical leadership and voice behavior literature. Ethical leadership enhances followers' promotive/prohibitive voice behaviors through their moral identity enhancement. The paper also confirmed that a proactive personality is a critical boundary condition in these relationships. Empirical evidence from the Eastern context has been added, and research directions have also been provided.","PeriodicalId":44018,"journal":{"name":"Journal of Economic and Administrative Sciences","volume":"65 9","pages":""},"PeriodicalIF":1.8,"publicationDate":"2024-01-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139381758","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}

This study aims to explore the influence of cross-country indicators of governance from African countries on public debt accumulation.Design/methodology/approachThe study deployed a quantitative research design technique. Secondary data was used in this study. The frequency of the data is annual, and it is available from 1996 to 2022 for 48 countries in Africa. The study deployed the system generalized method of moments for the estimation.FindingsThe study finds that countries with high regulatory quality standards, control corruption and ensure effective governance accumulate less government debt while countries that abide by the rule of law instead accumulate more government debt. The study also finds that economic growth and government revenue reduce government gross debt while government expenditure and investments increase public debt.Research limitations/implicationsDue to data unavailability, other factors which are likely to influence government debt accumulation were not included in the study as control variables. This is the limitation of the study.Social implicationsAfrican governments should strive to maintain high regulatory quality standards through the formulation and implementation of sound policies and regulations that permit and promote private sector development, and ensure quality and accountability of public and civil services. Governments are also urged to control corruption and enact good laws so that the enforcement of these laws will not worsen the risk of becoming debt-distressed.Originality/valueRecent studies on governance and public debt were focused on the Arabian Gulf countries, countries of the Middle East and North Africa (MENA) region and a combination of high and low-income countries. This study scrutinizes exclusively the effects of the quality of governance indicators on public debt accumulation, in the context of Africa.","PeriodicalId":44018,"journal":{"name":"Journal of Economic and Administrative Sciences","volume":" 51","pages":""},"PeriodicalIF":1.8,"publicationDate":"2023-12-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139144517","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}

This study compares symmetric and asymmetric GARCH models to forecast volatility in emerging nations like the G4 countries. Accurate volatility forecasting is vital for investors to make well-informed investment decisions, forming the core purpose of this study.Design/methodology/approachFrom January 1993 to May 2021, the study spans four periods, focusing on the global economic crisis of 2008, the Russian crisis of 2015 and the COVID-19 pandemic. Standard generalized autoregressive conditional heteroscedasticity (GARCH), exponential GARCH (E-GARCH) and Glosten-Jagannathan-Runkle GARCH models were employed to analyse the data. Robustness was assessed using the Akaike information criterion, Schwarz information criterion and maximum log-likelihood criteria.FindingsThe study's findings show that the E-GARCH model is the best model for forecasting volatility in emerging nations. This is because the E-GARCH model is able to capture the asymmetric effects of positive and negative shocks on volatility.Originality/valueThis unique study compares symmetric and asymmetric GARCH models for forecasting volatility in emerging nations, a novel approach not explored in prior research.

Furthermore, this study aims to examine the role of ethical climate as a potential mediator in the relationship between RL and ESP.Design/methodology/approachA sample of 415 employees from the healthcare sector of India was collected through a questionnaire-based survey by using the convenience sampling technique.

Furthermore, for robustness, they compare the results with two-stage least square (2SLS) regression estimates after considering the problem of endogeneity, overidentification, under-identification and weak instruments.FindingsThe findings show that among the selected macroeconomic variables, inflation, exchange rate and broad money have significant negative effects on the debt-GDP ratio. In contrast, military spending, corruption and interest rates appear to positively influence the same as per 2SLS results. From the policymaking perspective, SAARC countries should focus more on reducing military spending and make a concerted effort to augment investments in productive projects. Further, with strong fiscal consolidation and institutional quality, it is important to mitigate the frequent occurrence of corruption conundrums in emerging economies for the development of a transparent economic system.Originality/valueThe study is distinct from previous studies in two ways. First, to the best of the authors’ knowledge, there are no studies focusing on SAARC countries in the context of public debt. Second, the study expands the existing literature on public debt by taking into account both external and internal debts to decipher the within-country and cross-country determinants of debt accumulation.
