Design/methodology/approach – The research was conducted in the first half of 2019, among non-randomly selected subjects representing their households from Poland and Slovakia. The empirical part of the work is based on the results of research employing a structured standardized interview. Cluster analysis was used in the analysis of the results. Findings – The results of the research showed that the eating behaviors of Polish and Slovak consumers differ. Some Polish and Slovak consumers follow the principles of healthy eating. Among Polish consumers we distinguished four types of consumers: I – “Driven by the principles of healthy eating”; II – “Implementing the principles of healthy eating”; III – “Ordinary bread eaters”; IV – “Consciously unaware.” In turn, among Slovak consumers, we distinguished also fourth types: I – “Driven by the principles of healthy eating”; II – “Exercise and drink milk!”; III – “Not attaching importance to healthy eating”; IV – “Eat tastily and healthily.” The distinguished types of consumers can be the basis for the food market segmentation. Knowledge of the typology based on declared eating behaviors and selected aspects of the lifestyle may enable food producers to develop an appropriate marketing strategy. Research implications/limitations – A certain limitation may be the non-random sample selection. An important aspect would also be to expand the analyzed research thread with additional aspects related to eating behavior and lifestyle. Another limitation is that the clusters were delivered in two separate processes for Poland and Slovakia, respectively. As a result, the clusters are different and represent two different typologies. Originality/value/contribution – The research may be an important source of information for researchers dealing with consumer typology. The distinguished types of consumers can be the basis for the food market segmentation.","PeriodicalId":40031,"journal":{"name":"International Journal of Economics and Management","volume":"10 1","pages":"68 - 101"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79202345","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}

Previous research that uses Benford’s law does not split the sample into a fraud and a control group; however, this method is used in logistic regression and data mining analysis. Design/methodology/approach – The sample comprises 126 observations of Polish non-financial companies listed on the Warsaw Stock Exchange for the years 2010-2021. The author uses first, second, and first-two digits analysis as a proxy for earnings management detection. Findings – The results indicate that fraudulent companies have different deviations in the digits than control firms. Accordingly, the statistical test results indicate that control companies have weaker conformity with the Benford distribution than fraudulent companies. Research implications/limitations – The study sample is limited to 126 observations, which is due to the small number of listed firms that received a monetary fine from the Polish Financial Supervision Authority (UKNF Board) for violation of IAS/IFRS principles related to their financial statements during the study period. Originality/value/contribution – The author offers a significant contribution to the accounting literature by proposing the separation of fraudulent and control observations in Benford analysis due to differences in the deviations of digits. Also, analyzing the full sample may lead to the identification of inappropriate areas for further auditor analysis.","PeriodicalId":40031,"journal":{"name":"International Journal of Economics and Management","volume":"15 1","pages":"216 - 236"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81986815","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}

{"title":"Public sector spending, governance, and economic growth in Sub-Saharan Africa","authors":"Sulemana Mumuni, A. Njong","doi":"10.22367/jem.2023.45.08","DOIUrl":"https://doi.org/10.22367/jem.2023.45.08","url":null,"abstract":"Abstract Aim/purpose – This study examined the impact of public sector spending and governance on economic growth in Sub-Saharan Africa (SSA) and further assessed the role of governance in the causal relationship between public sector spending and economic growth in the sub-region. Design/methodology/approach – The study employed the Panel Corrected Standard Errors (PCSE) estimator on data spanning the period 2002 to 2020 across a sample of 31 selected countries in SSA. To check for the robustness of the results, we adopted the Dumitrescu and Hurlin (2012) panel non-causality test to detect Granger causality in the relationships among the variables. Findings – The findings show that spending in the public sectors alone, such as education and health, does not always yield the needed outcome of promoting economic growth. Government education expenditure stimulates economic growth in SSA, albeit the effect is statistically insignificant, whereas government health expenditure has a growth-limiting effect in SSA. The results reveal that government effectiveness, rule of law, political stability, and absence of violence/terrorism are among the governance indicators that can help to fast-track economic prosperity in SSA. However, the results further show that good governance can act as a stimulant to invigorate the effectiveness of public sector spending in achieving economic growth in SSA. The growth-enhancing complementary role of good governance to public sector spending is robust across all governance indicators except political stability for government education spending and regulatory quality for government health spending. Research implications/limitations – The findings imply that strengthening good governance in SSA is non-negotiable in managing and using public funds allocated to the public sectors and in achieving sustainable economic growth, poverty alleviation, and income inequality reduction in the sub-region. However, the findings of this study are limited to the SSA region and may not apply to other regions of the globe. Originality/value/contribution – The contribution of this paper is that it examines the moderation effect of governance in the causal relationship between public spending and economic growth in SSA while accounting for cross-sectional dependence. The paper also contributes to the existing literature by using disaggregated governance and public sector spending components to ascertain the robustness of the results and better inform policy.","PeriodicalId":40031,"journal":{"name":"International Journal of Economics and Management","volume":"153 1","pages":"147 - 181"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74374165","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 analysed and compared the effects of parental financial socialisation and financial literacy on Indonesian and Malaysian university students' financial behaviour. In total, 204 students from the Faculty of Human Ecology at IPB University and Universiti Putra Malaysia participated in the study. Data were gathered using a self-reporting questionnaire using the convenience sampling method. The independent sample t-test and multiple regression analysis were performed on the data. The results of the t-test showed that Malaysian students scored significantly higher in parental financial socialisation and financial behaviour but lower in financial literacy than Indonesian students. Moreover, the regression analyses revealed that parental financial socialisation and students' financial literacy were highly significant in influencing the sampled students' financial behaviour. However, by splitting the sample based on the student's country of origin, this study demonstrated that Malaysian students' financial behaviour was only significantly influenced by parental financial socialisation, while Indonesian students' financial behaviour was only significantly determined by financial literacy. These findings implied that Malaysian parents were more involved in shaping their children's financial behaviour or decisions. In contrast, Indonesian students were more independent from their parents, and their financial literacy level predominantly influenced their financial behaviour.","PeriodicalId":40031,"journal":{"name":"International Journal of Economics and Management","volume":"56 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-12-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87476013","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}

Furthermore, the research model can explain 59.9 percent of the significant variance in MFI performance. This study contributes to the theoretical expansion of the resource-based view (RBV) in forecasting the MFIs success.

This study utilised data of 26 conventional banks and 16 Islamic banks from Malaysia from 2012 to 2020. A Random Effect model was used to investigate the difference between conventional and Islamic banks’ non-performing loans as well as the influence of ownership on non-performing loans of conventional and Islamic banks. Results showed no significant differences for non-performing loans of conventional and Islamic banks. This result implies that despite the fact that Islamic banks may benefit from lower agency costs, this does not considerably decrease the likelihood of non-performing loans. Foreign Islamic banks shows higher non-performing loans in comparison to domestic Islamic banks. However, there were no significant differences for non-performing loans between foreign conventional and domestic conventional banks. This study suggests that Islamic bankers, particularly those intending to expand into other countries, investigate nonperforming loans, which can impact the risk of a foreign Islamic bank.","PeriodicalId":40031,"journal":{"name":"International Journal of Economics and Management","volume":"32 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-12-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82951251","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}

The evaluation is hindered by the contemporaneous emergence of the COVID-19 pandemic, which acts as a confounding factor in adopting the new payment instrument. To disentangle the effect of those variables, we collected data from 617 respondents consisting of customers and merchants, employed a structural equation model with SmartPLS, asses fourteen hypotheses with demographic factors included as moderating factors. The result of the study successfully disentangles the policy impact from the pandemic impact and separates the risk of a pandemic from common risks. We verify that the pandemic and government intervention had significant direct and indirect effects on the intention to use QRIS, with the habit being the most influential component, outperforming other technology adoption determinants. This study, therefore, contributes to the advancement of the literature on the topic of technology adoption and government intervention and suggests that this measuring approach can be used as a complementary instrument to assess the impact of central bank policy on the public.","PeriodicalId":40031,"journal":{"name":"International Journal of Economics and Management","volume":"27 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-12-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91081227","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}

We model stocks’ returns of these countries between January and December 2020, decomposing the errors’ heteroskedasticity to account for main international and local events related to COVID-19. These events have been included as structural breaks and measured using dichotomous variables. Both local and international events were found to be associated with significant variations in volatility; however, local events seem to have impacted volatility to a lesser extent compared to international events. The announcement of the status of pandemic by the WHO had the greatest impact on volatility across the GCC markets, even greater than the impact associated to the drop in oil prices. The announcement of local approval of vaccine led to a reduction in volatility in UAE (ADX), Qatar, Saudi Arabia and Bahrain.","PeriodicalId":40031,"journal":{"name":"International Journal of Economics and Management","volume":"13 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-12-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81913972","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}
