    An Econophysics Perspective on Green Bonds and Stock Market Nexus: Can Green Finance be an Investment Option for Emerging Stock Markets?
    (Başkent Üniversitesi İktisadi İdari Bilimler Fakültesi, 2024-03-28) Acikgoz, Turker
    Green bonds are one of the most fascinating financial innovations that offer a solution to climate change and sustainable development from the financial point of view. In this study, we employ methods from statistical physics to examine the multifractal features of cross-correlations between green bonds and emerging stock markets. Utilizing multifractal detrended cross-correlation analysis (MFDCCA) on return and volatility series, our findings reveal significant cross-correlations between green bonds and emerging stock markets. The MFDCCA results uncover multifractal features and long-range cross-correlations between the two assets. Notably, volatility cross-correlations exhibit persistent behavior, while return cross-correlations vary across small and large fluctuation periods. These findings hold practical implications for policymakers and investors involved in green bonds and emerging stock markets.

    Explaining The Relationship Between Person-Organization Fit And Entrepreneurial Intention Through Workplace Ostracism And Loneliness
    (Başkent Üniversitesi İktisadi İdari Bilimler Fakültesi, 2024-03-10) Basar, Ufuk; Karamanlioglu, Almula Umay; Sigri, Unsal
    PurposeThe entrepreneurial intention of employees refers to the motive of those who work in a company to resign and start their businesses instead of continuing to be wage earners. It is one of the under-studied aspects of entrepreneurship research. Accordingly, this research paper aimed to find out whether perceived person-organization fit was related to the entrepreneurial intentions of employees and whether perceived workplace ostracism and loneliness mediated this process.Design/methodology/approachA cross-sectional study was conducted to achieve the purpose. The data were collected through a questionnaire technique from a total of 572 employees. Participants were from 20 different provinces of Turkey and 27 different sectors. Hypotheses were tested through the structural equation modeling technique.FindingsFindings indicated that a lack of perceived person-organization fit resulted in entrepreneurial intention. Workplace ostracism resulted in workplace loneliness. Workplace ostracism and loneliness significantly mediated the relationship between perceived person-organization fit and entrepreneurial intention.Originality/valueTo the best of authors' knowledge, this study was the first to establish and test the relationships between person-organization fit, entrepreneurial intention, workplace ostracism and loneliness. In this regard, findings can benefit researchers and practitioners in better figuring out why some employees leave their companies to start their businesses while others do not.

    Preferences for Intuition and Deliberation in Decision-Making in the Public Sector: Cross-Cultural Comparison of China, Taiwan, the Philippines, and the USA
    (Başkent Üniversitesi İktisadi İdari Bilimler Fakültesi, 2024-02-19) Svenson, Frithiof; Ermasova, Natalia; Cetin, Fatih; Launer, Markus A.
    This paper explores hypotheses based on Hofstede's cultural framework showing that decision-makers' culture impacts their implicit choice. How people make decisions is tested through the behavioral dimension preference for intuition/preference for deliberation based on data from 1,233 employees in China, Taiwan, the Philippines, and the USA. This study reveals significant variation in individuals' intuitive and affective decision-making in the public sector across different countries. Individuals' deliberative decision-making is impacted by long-term orientation and uncertainty avoidance. The study finds that Eastern countries (China, the Philippines, and Taiwan) have higher scores for intuitive/affective decision making than the Western countries (the USA).

    Multifractal Detrended Cross-Correlations between Green Bonds and Commodity Markets: An Exploration of the Complex Connections between Green Finance and Commodities from the Econophysics Perspective
    (FRACTAL AND FRACTIONAL, 2024-03-08) Acikgoz, Turker; Gokten, Soner; Soylu, Abdullah Bugra
    Green bonds represent a compelling financial innovation that presents a financial perspective solution to address climate change and promote sustainable development. On the other hand, the recent process of financialisation of commodities disrupts the dynamics of the commodity market, increasing its correlation with financial markets and raising the risks associated with commodities. In this context, understanding the dynamics of the interconnectivity between green bonds and commodity markets is crucial for risk management and portfolio diversification. This study aims to reveal the multifractal cross-correlations between green bonds and commodities by employing methods from statistical physics. We apply multifractal detrended cross-correlation analysis (MFDCCA) to both return and volatility series, demonstrating that green bonds and commodities exhibit multifractal characteristics. The analysis reveals long-range power-law cross-correlations between these two markets. Specifically, volatility cross-correlations persist across various fluctuations, while return series display persistence in small fluctuations and antipersistence in large fluctuations. These findings carry significant practical implications for hedging and risk diversification purposes.

    The İmpact Of Fluctuating İnternational Fertiliser Prices And Exchange Rates On Domestic Fertiliser Prices İn Türkiye
    (AGRICULTURAL ECONOMICS-ZEMEDELSKA EKONOMIKA, 2024-12-14) Bor, Ozgur; Dagistan, Nihat
    This study aims to examine the relationship between domestic and international prices of di -ammonium phosphate (DAP) and urea fertilisers together with exchange rates in Tiirkiye using the non-linear autoregressive distributed lag (NARDL) model on monthly data for the period of January 2011 to September 2022. The result of the study provides empirical evidence about the presence of asymmetries in the short and long -run among these fertilisers. The findings of the study confirm that international prices of di -ammonium phosphate and urea fertilisers have a symmetric effect in the long -run and exchange rate of the Turkish lira to US dollars has an asymmetric effect on the domestic prices of fertilisers in the short run. This is the first study in Tiirkiye to delineate the dynamic simultaneous interaction among these markets and its findings can be extremely useful for academicians, and policymakers to make decisions regarding the market structure of countries that do not have sufficient domestic resources for fertiliser supply and are dependent on imports.

    The Impact Of High-Performance Human Resource Practices On Subjective Career Success: The Mediating Role Of Psychological Capital And Organizational Commitment
    (JOURNAL OF EAST EUROPEAN MANAGEMENT STUDIES, 2024-06-19) Toyata, Berk; Kizrak, Meral; Cakar, Mehmet
    Utilizing insights from positive psychology, social exchange theory, and social cognitive career theory, this study aims to investigate the mediating role of psychological capital and organizational commitment in the relationship between high-performance human resource (HR) practices and subjective career success. Data were collected from a sample of 429 private sector employees working on European Union projects in Turkey. Hypotheses were tested using regression, correlation, and mediation analyses, as well as Sobel test statistics. Results indicate that high-performance HR practices, organizational commitment, and psychological capital positively influence subjective career success. Additionally, there is evidence that, unlike organizational commitment, psychological capital mediates the relationship between high-performance HR practices and subjective career success. Our study underscores the need for organizations to foster and develop psychological capital among their employees to maximize the effectiveness of HR practices in promoting subjective career success.

    The Mediating Effect Of Psychological Safety On The Relationship Between Authentic Leadership And Turnover Intention
    (MIDDLE EAST JOURNAL OF MANAGEMENT, 2024-07-20) Durukan, Mehmet Hakan; Kibaroglu, Gamze Guner; Basim, H. Nejat
    This study was conducted to examine the role of psychological safety in the effect of authentic leadership on turnover intention. In this framework, from the perspective of leader-member interaction theory, it has been shown that an authentic leader can reduce turnover intention. Within the scope of the study, data were collected from 340 participants by survey method and analysed. According to the results of the research, there is an inverse and significant relationship between authentic leadership and turnover intention. In addition, while authentic leadership affects psychological safety in the same direction, psychological safety negatively affects turnover intention. In addition to these results, the most important result of our study is that psychological safety plays a mediating role in the effect of authentic leadership on turnover intention. The results of the study showed that creating a transparent work environment based on authentic leadership and establishing basic psychological safety can reduce individual turnover intention.

    The Retreat From Bıst: Insıghts Into Foreıgn Portfolıo Investment Movements
    (EKONOMI POLITIKA & FINANS ARASTIRMALARI DERGISI, 2024-11-15) Alp, oezge S. E. Z. G. I. N.; Hazar, Adalet; Babuscu, Senol
    The need for rapid growth and development in developing countries increases the demand for capital. As a result, foreign portfolio investments are of great importance, especially in emerging markets, as they help meet capital needs. However, their ability to move quickly also introduces high volatility to financial markets. This study examines changes in the share of foreign portfolio investors in Borsa Istanbul from 2004 to 2023, aiming to provide long-term insights to market participants. Initially, changes in the foreign portfolio investor ratio over time are graphically analyzed alongside the BIST 100 index and the average interest rate of deposits with a maturity of up to 3 months. These changes are evaluated in the context of both global and local developments. The study then investigates the causal relationship between the foreign portfolio investor ratio and the BIST 100 index using a cointegration test and a causality test based on the VECM model. The findings show a one-way causality from the BIST 100 index to the foreign portfolio investor ratio, indicating that foreign investors' market movements are largely influenced by the performance of the BIST 100, and local market dynamics significantly affect foreign capital inflows.
