They lead to greater productivity and efficiency, and therefore to better economic results. The purpose of this article is to examine the state, interrelation and the impact of innovative activities on the economic growth of Serbia. The paper first uses standard multiple regression and concludes that in the period from 2004 to 2020, the number of registered patents did not contribute, while the gross expenditures for research and development (GERD) contributed positively and significantly to the growth of the Serbian GDP. Therefore, it can be said that Serbia is facing a kind of innovation paradox, since the growth of allocations coexists with a dramatic decrease in the number of registered patents. Its second part is based on the construction of the corresponding Vector autoregressive VAR(1) model that traces the causal relationship between GERD and the economic growth of Serbia in the period from 1997 to 2020. It follows that while GERD does not cause GDP in the Granger sense, the GDP causes GERD allocations for innovative activities in Serbia. The scientific research work in Serbia is not efficient and effective enough because it draws funds from the GDP, but does not meet expectations and does not produce tangible results, especially in the expected number of registered patents. Therefore, it is necessary to build an appropriate incentive environment that would stimulate more adequately and value new innovative ventures.","PeriodicalId":33155,"journal":{"name":"Acta Economica","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-12-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41935991","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 COVID-19 pandemic had a negative effect on economic growth and resulted in a severe decline in the financial performance of companies. In addition, it disrupted many business and economic development opportunities in South Africa. The study was conducted to investigate the influence of the COVID-19 pandemic on the financial performance of selected retail firms listed on the Johannesburg Stock Exchange (JSE). Panel data analysis was adopted as a methodology to achieve the study objectives. The COVID-19 pandemic was found to have exerted a statistically significant negative impact on financial performance. Positive significant relationships emerged between financial leverage, firm size, financial liquidity and financial performance of selected JSE-listed retail firms. Lastly, growth in sales was found to be positive but exerted a weak significance on financial performance. The study contributes to the existing literature on the influence of the COVID-19 pandemic on the financial performance of listed retail entities in South Africa.","PeriodicalId":33155,"journal":{"name":"Acta Economica","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-12-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42057281","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}

Tosin – Amos","doi":"10.7251/ace2237167a","DOIUrl":"https://doi.org/10.7251/ace2237167a","url":null,"abstract":"This paper investigates the effect of food price inflation on the public health improvement as measured in terms of life expectancy, infant mortality rate, under five mortality rate and neonatal mortality rate in six selected African countries with high misery index for the period from 2000 to 2020. The Augmented Mean Group and Common Correlated Estimation Mean Group were used to determine the effect, as well as Westerlund Cointegration tests. Our findings revealed that rising food prices have a significant detrimental effect on nourishment and consequently lead to higher levels of infant under five and neonatal mortality while reducing the expected life expectancy in the African countries. High food price inflation also has a long run effect on public health. The implication of the result shows that with high rate of food prices coupled with poor child health, the Sustainable Development Goals target of ending preventable deaths of newborns and children under age of 5, and the aim of having a neonatal mortality rate of 12 or fewer deaths per 1,000 live births, and an under-five mortality rate of 25 or fewer deaths per 1,000 live births, by 2030 may not be realistic. Therefore, African Governments should gear up efforts towards reducing food price inflation, improving health expenditure, per capita income and enabling environment for safe sanitation, especially for pregnant women and little children. Also, Governments should create enabling environment for sanitation and access to safe drinking water.","PeriodicalId":33155,"journal":{"name":"Acta Economica","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-12-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42795826","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}

Therefore, in economic theory, the rate of economic growth is a function of investment. This research includes an analysis of the impact of selected key macroeconomic indicators (independent variables) on the state and trend of investments in the European Union as a dependent variable. The research covers the period from 2012 to 2021. The following independent variables are chosen: GDP growth rate, interest rate, inflation, unemployment, income from indirect and direct taxes, public debt and budget deficit. The research shows the impact of these variables on the investments of the European Union, the dependent variable. The results of the regression analysis show that interest rates, unemployment, revenues from indirect taxes, as well as the public deficit and public debt have a negative and statistically significant direction in relation to investments. The GDP growth rates as well as direct tax revenues are statistically insignificant, but they have a positive regression coefficient on investments. Inflation rate is also an insignificant variable, but with negative impact on investments. The chosen model in the context of the joint action of all independent variables is statistically significant given that the coefficient of determination is 0.99. The results of the F test indicate statistical significance below 5%, so the model offers enough degrees of freedom (df) to vary the variables and statistically acceptable rating. Finally, the obtained results are significantly consistent with previous research and theoretical assumptions.","PeriodicalId":33155,"journal":{"name":"Acta Economica","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-12-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49087778","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}

Composing a statistical model implies grouping the factors that determine the contributions of qualitative preference to business efficiency of the whole company. Empirical material is obtained by surveying the target group, and the response pattern to clarify the management problem is factor analysis. The purpose of factor analysis is to rationalize the number of dependent variables of business efficiency in relation to qualitative and quantitative requirements within the surveyed target group. Considering the modern lifestyle, it is reasonable to assume that general dissatisfaction level is increasing every day. This includes professional orientation, working conditions, leisure time management and all levels of interpersonal relationships such as collegial, friendly, partner and family relationships. It is reasonable to assume that within business systems there is a space for recognizing this dimension and its careful analysis that respects the non-economic dimension of employees’ (dis) satisfaction and manages business efficiency in terms of non-economic factors. This paper aims to present thorough analysis of grouped factors that are basically non-financial; they represent a group of spiritual factors that contribute to a better internal climate of the company. All this leads to a prosperous company management that can represent and promote the company in public well.","PeriodicalId":33155,"journal":{"name":"Acta Economica","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43971310","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}

Significant attention is paid to the analysis of the interdependence of (in)stability of the state and the economic development of small countries. The position of the Open Balkan and its members is also analysed on the basis of the selected global composite indices. An important subject of the analysis is also the condition of institutional capacities of the members of the Open Balkan and their institutional cooperation from the perspective of faster progress towards the European integration. Two main hypotheses have been tested in the paper: (H1) CEEs countries are not a homogeneous group of countries; and (H2) The Western Balkans is a relatively homogeneous regional integration. To test the convergence hypothesis between 16 Central and Eastern European countries (CEEs), annual data from World Bank’s database on the value of real gross domestic product per capita (in constant dollars 2017, PPP) in the period 2000-2026 were used (projected values for the period until 2026). We employed the method developed by Phillips & Sul (2007) that allows identification of clusters of convergence on the basis of an algorithm that is data-driven and thereby avoids a priori classification of the data into subgroups. Based on the results obtained, it can be concluded that Serbia is the “locomotive” of the Western Balkans and that all countries in this area should join the regional initiative for cooperation, the Open Balkan.","PeriodicalId":33155,"journal":{"name":"Acta Economica","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44294156","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}
