These changes can be attributed to shifts in regional and global economic conditions, as well as short-term decisions made by governments. Recently, the COVID-19 pandemic has led to increased government spending and borrowing, rendering governments more vulnerable. In this context, the implementation of fiscal rules has gained renewed attention. However, to construct a more resilient infrastructure against future crises, it is not only the national fiscal rules that are critical, but also the presence of supranational fiscal rules that can ensure coordination and discipline among countries has become increasingly important. This study, therefore, seeks to analyze the impact of national and supranational fiscal rules on fiscal performance in 31 advanced economies over the period 2000-2020, utilizing the fixed-effect panel threshold model approach. The results indicate that national fiscal rule implementations become effective after a certain threshold level, whereas supranational fiscal rules are effective both below and above a specific debt threshold. This implies that while both types of fiscal rules are effective, supranational rules stand out in terms of their magnitude and their effectiveness even at lower levels of debt. These findings are expected to guide policymakers in evaluating fiscal rule policies and balancing local needs with the achievement of regional objectives.","PeriodicalId":516075,"journal":{"name":"Mehmet Akif Ersoy Üniversitesi İktisadi ve İdari Bilimler Fakültesi Dergisi","volume":" 22","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140391607","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 study contains semi-annual data of non-financial BIST 100 Index companies spanning from January 2010 to June 2023. Companies’ VaR are calculated using Monte-Carlo simulation, bootstrap, delta-normal, and historical simulation methods and included in separate econometric models as dependent variables. Financial decisions are represented through financial ratios in line with the basic principles of corporate finance and included as explanatory variables in econometric models. The study employs a five-stage panel data methodology. \u0000Findings reveal that the impact of financial decisions regarding working capital management, capital structure, dividend pay-out, and growth policies on companies’ VaR differ according to the VaR calculation method. Notably, findings show that financial decisions explain the changes in VaR calculated by Bootstrap method with the highest success rate, aligning with existing finance literature. Prudent financing policies and flexible investment strategies in working capital management, enhanced profitability and financial performance, and sales growth exhibit dampening effects on VaR. Conversely, heightened leverage and long-term borrowings, decisions to pay-out dividends, and growth in foreign investments have increasing effects on VaR. Furthermore, the study identifies the Covid-19 pandemic as exerting a negative influence on VaR.","PeriodicalId":516075,"journal":{"name":"Mehmet Akif Ersoy Üniversitesi İktisadi ve İdari Bilimler Fakültesi Dergisi","volume":"31 10","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140396173","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}

Due to the absence of a specific closing time in the cryptocurrency market, the closing time of the daily data is taken as 23:59 UTC. Initially, an appropriate volatility model for the cryptocurrency market is established using the GARCH, EGARCH, and TGARCH models. The most appropriate model for BTC is ARMA(1,0)-EGARCH(1,1) and ARMA(1,0)-GARCH(1,1) for ETH. The results of the analysis indicate a leverage effect in the cryptocurrency market, where negative shocks cause a more significant increase in volatility than positive shocks. Based on this volatility structure, the DoW and MoY are analyzed. For BTC, returns on other days are lower compared to Mondays. However, for ETH, returns on Thursdays are lower than those on Mondays. In terms of volatility, both BTC and ETH show that the highest volatility occurs on Mondays. For the MoY effect, neither BTC nor ETH don’t exhibit a significant effect in the mean equation. Nevertheless, the variance equation indicates that January has higher volatility compared to other months, indicating the presence of a MoY effect in terms of volatility.","PeriodicalId":516075,"journal":{"name":"Mehmet Akif Ersoy Üniversitesi İktisadi ve İdari Bilimler Fakültesi Dergisi","volume":"7 21","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140396641","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}

One of the key findings of this study is the presence of an asymmetric relationship between variations in income and overall healthcare expenditure. This means that changes in income levels do not have uniform effects on health expenditure, and the direction of these effects depends on whether income is rising or falling. Interestingly, the research reveals that both increases and decreases in income lead to a rise in total health expenditure. However, the impact of income declines on health expenditure is more pronounced. In other words, when people experience a decrease in income, they tend to allocate a larger portion of their reduced resources to health-related expenses. This highlights the significant financial strain that income reductions can place on individuals and households when it comes to healthcare costs. This pattern of asymmetric effects also extends to government or compulsory health expenditures. When income falls, the government's role in funding health expenses becomes more prominent, as individuals rely more on public healthcare services during economic downturns. Furthermore, the study sheds light on the intriguing relationship between income shifts and voluntary or out-of-pocket health expenses. Positive income shifts are found to be associated with a reduction in voluntary health expenditure. This suggests that as people experience an improvement in their financial situation, they may opt for less costly or more efficient healthcare services, leading to a decrease in out-of-pocket expenses. Conversely, when income levels decrease, individuals may find themselves with limited options, potentially resorting to more expensive private healthcare services or bearing a greater burden of out-of-pocket expenses. This finding underscores the financial vulnerability that can accompany negative income shifts.","PeriodicalId":516075,"journal":{"name":"Mehmet Akif Ersoy Üniversitesi İktisadi ve İdari Bilimler Fakültesi Dergisi","volume":"260 ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140448186","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}

In this study, it is analyzed in 7 countries (Bahrain, United Arab Emirates, Israel, Qatar, Qatar, Kuwait, Oman and Saudi Arabia) in the high-income Middle East and North Africa (MENA) countries group. Using data on public and commercial services, residential, industrial, total other sectors (agriculture, transportation), total electricity consumed and GDP for the period 1990-2021, the relationship between sectoral electricity consumption and economic growth is analyzed with the Panel Granger causality test. As a result of the analysis, while there is no long-run relationship between public and commercial services, residential, total other sectors (agriculture, transportation) and total electricity consumed and growth, there is no causality relationship between these variables, while there is a unidirectional causality relationship from growth to electricity consumption in industry. Contrary to previous studies, the reason for the absence of a causality relationship from electricity consumption to GDP growth in this study is that export revenues from natural resources and high-tech products make a significant contribution to the GDP formation of the countries included in the analysis. These results show that, contrary to the same directional relationship between electricity consumption and GDP growth in the literature, it is not valid for natural resource and high technology exporter countries. We can say that the results of the study make an important contribution to the literature in this respect.","PeriodicalId":516075,"journal":{"name":"Mehmet Akif Ersoy Üniversitesi İktisadi ve İdari Bilimler Fakültesi Dergisi","volume":"107 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140445713","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}
