Abstract:
This study aims to investigate the effects of personality traits, in addition to basic financial literacy, private pension literacy and behavioural factors on Private Pension System (PPS) participation using machine learning algorithms. The PPS participation model was trained using both random forest and LightGBM algorithms, and the contributions of model inputs in the prediction of pension participation were interpreted using the Tree SHAP algorithms with swarmplots. The data employed in the empirical analysis is survey data collected from the Şırnak province of Türkiye with a sample size of 449. The findings of the study shows that: (i) PPS participation is more likely for females and middle-aged people; (ii) High basic financial literacy has a negative impact on PPS participation; (iii) Extraversion is the key personality trait affecting PPS participation; (iv) Advanced pension literacy has more impact on participation than simple pension literacy: (v) Present-fatalistic tendency is key behavioural factor and it negatively affects PPS; (vi) Present-hedonistic, conscientiousness, future-time orientation, and locus of control tendencies increase PPS participation. Furthermore, the distribution of colours in LightGBM has a greater degree of uniformity in both directions compared with the random forest algorithm. Finally, to increase PPS participation, the results of the study suggest the implementation of the following policy measures: Tailored pension literacy programmes can help to increase pension participation rates. Incentives should be created to prevent narrow-minded behaviour and establish a sense of protection and control around PPS, targeting middle-aged individuals and women.

Abstract:
The importance of information communication technology in fueling economic growth is widely acknowledged. In the current digital era, the International Digital Economy and Society Index (I-DESI) offers a more precise depiction alternative to the ICT indicators by serving as a better proxy for changes in the factors of production. It monitors the advancement of ICT in the EU27 and 14 non-EU nations, highlighting their strides towards a technologydriven economy. The objective of the study was to evaluate the influence of the I-DESI on economic growth through the utilization of the panel data method. Hence, gross domestic product (GDP) measured at constant prices was utilized as the dependent variable in the analysis, while the Index of Digital Economy and Society Integration (I-DESI), calculated by the European Commission, served as the independent variable. However, it’s important to note that the described index is current and limited at present. In line with this constraint, only four years of data, spanning from 2015 to 2018, were available. To ensure the accuracy of the model, diagnostic tests were conducted, and the Driscoll-Kraay standard error model was employed to assess the outcomes. Two models were constructed to achieve this goal, with the initial one revealing the relationship between the I-DESI and economic growth. The second model aimed to pinpoint the dimensions of the I-DESI that had the greatest impact on growth. According to findings obtained from the analysis, I-DESI and certain subdimensions which are digital skills, use of internet, integration of digital technology, and digital public services affect economic growth positively and significantly. A one percent increase in I-DESI results in a one percent increase in GDP. Similarly, each subdimension mentioned, where meaningful relationships have been identified, possesses explanatory power for GDP. Furthermore, evaluating the coefficient of these independent variables, changing the weight of dimensions can be considered.

Abstract:
To develop a public policy, it is important to understand the experiences of forced migrants. This study reveals the effects of forced migration on public finances in countries hosting displaced people. In this context, public policy support for access to basic humanitarian needs such as education and health, which are semi-public goods, will be evaluated through a quantitative analysis. Interviews with refugees within the scope of this research draw a picture of the current situation. Thus, evaluating the effectiveness and shortcomings of existing policies and determining the policy support needed are among the unique values of this research. Since migration is a dynamic process, it is also aimed to provide a basis for future studies in this field and to reveal the current situation.

Abstract:
The status of countries within the global value chain varies depending on the importance of national production capabilities in the global economy. From this perspective, there is a need for a value-added production approach that focuses on innovation and competitiveness. Technological advances and institutions are considered to play a significant role in transforming the economy towards an innovation-driven one to meet these needs. The aim of this paper is to investigate the relationship among technological advances, the rule of law as a proxy for institutions, value-added production, and competitiveness in a way that reflects crosscountry divergence. Through an analysis employed independently of countries’ existing levels of development, it will be possible to evaluate whether the factors associated with institutions and innovation can produce similar results in all circumstances and for each country. In this context, a panel causality analysis that considers cross-sectional heterogeneity is employed. The analysis shows bidirectional causality between the variables, except for value-added to the rule of law. However, the results also support the existence of cross-country divergence. These findings suggest that future policy plans should be designed to consider the multidimensional nature of country-specific factors, alongside technological advances and the rule of law, and to ensure the integration of both national and international economic objectives.

Abstract:
Realisation of specialisation in areas dominated by technological production structure and the technological level of exported goods are essential determinants of macroeconomic performance. Therefore, the export structure and technological level of exported goods are highly significant. In this study, the relationship between real GDP and exports of goods produced in BRICS-T countries with low, medium, and high levels of skill and technology is investigated. In the panel data analysis using data for the period 1995–2020, the cointegration relationship between the variables was examined, and it was concluded that there is no long-run relationship between real GDP and goods produced in labour-resource intensive, low, medium, and high skill and technology levels of countries. In addition, a causality test using Dumitrescu and Hurlin’s (2012) linear heterogeneous model was carried out. The test results showed a unidirectional causality relationship between real GDP and goods with low and high skill and technology but a bidirectional causality relationship between real GDP and labour-resource-intensive goods.

Abstract:
Ceremonial economics explores how traditional values, myths, and rituals intersect with economic practices and institutions. It differentiates between “ceremonial” practices based on tradition and cultural values and “instrumental” practices based on efficiency and problem-solving capabilities. This field, rooted in institutional economics, emphasizes the tension between preserving established social orders and fostering innovation. Scholars can gain insights into the broader implications of economic systems by understanding how ceremonial practices influence economic behavior and social cohesion. This pluralistic approach comprehensively analyzes how ceremonial and instrumental practices interact within various economic systems. The main goal of this study is to develop a detailed and all-encompassing framework for ceremonial economics. A key aspect of this will involve comparing ceremonial economics principles with institutional economics. Additionally, the study will delve into various aspects of ceremonial economics, specifically focusing on cultural and social aspects. Furthermore, the study conducts four examples to provide practical insights into the application of ceremonial economics.

Abstract:
The visibility and dependability of multinational corporations’ products increase with the fact that they introduce their goods to markets in other nations through foreign direct investments. The method for presenting products to international markets through foreign direct investments reveals the product’s reputation and therefore the brand’s development value. This study examines the relationship between foreign direct investments and brand value in Australia, Canada, China, France, India, Japan, Spain, the USA, and the UK for the period 2007-2023. The majority of studies in the literature attempt to explain the impact of brand value on foreign direct investments. However, very few studies explain the impac foreign direct investments on brand value and 1st generation unit root tests were generally used. Unlike existing studies, In this study, the second-generation unit root test, Durbin-Hausman cointegration, and Common Correlated Effects Mean Group estimation methods were used. As a result, it is anticipated that this study will contribute to the literature in this regard. The findings show that increases in foreign direct investments boost brand value.

Abstract:
In the past century, the key technologies that shaped societal and economic transformation were mechanical, electrical, and automation technologies. In the current century, there are strong trends indicating the prominence of artificial intelligence technology. Therefore, artificial intelligence technology has become more important for all countries. The success of countries in artificial intelligence technology is only possible with well-designed artificial intelligence policy tools. It is important to measure the level of technological advancement for the formulation of policies. However, efforts to measure the scientific and technological advancement of artificial intelligence technology are insufficient. Therefore, this study aims to develop a framework to measure the scientific and technological progress of AI technology. The developed framework includes the number of publications and citations, the number of high-impact scientific journals, the number of patent applications, the number of universities ranked in the top thousand in the field of computer science, the number of international high-impact conferences, and the total number of researchers in higher education. Through these criteria, the level of scientific and technological progress of the countries has been analysed in detail. The findings clearly revealed the leading position of the USA in this field. China followed the USA. These two countries are clearly and positively differentiated from the other countries. Other countries with good performance are the UK, the Netherlands and Germany.

Abstract:
This paper examines the factors that determine air transport in the BRICS countries, which account for approximately 42% of the world’s population and occupy an important position among developing countries in terms of economic size. In more detail, in this study, air transport examines two different models, passenger and freight transport. The research is carried out for the period 1996-2020. Panel data methods were used as analysis methods. According to the results of the analysis, both air passenger transport and air freight transport act together with their macroeconomic and socioeconomic determinants in the long term. Income is positive and significant in the air passenger transportation model, while income is insignificant in the freight transportation model. In addition, inflation, exchange rate, industrialisation and urbanisation on a country basis are important determinants of both air passenger transport and air freight transport for BRICS-T.
