    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.

    Effect of Festival Satisfaction on Destination Loyalty through Destination Overall Image: The Case of Alaçatı Herb Festival
    (ISTANBUL BUSINESS RESEARCH, 2024-12) Ozkan, Ayse Arslan; Yildiz, Erkan
    This study examines the relationships among festival success factors, festival satisfaction, destination image and destination loyalty. Based on the literature review, festival success factors were identified and a model was developed to measure the direct impact of these factors on destination loyalty and the impact of these factors through the overall image of the destination. Data were collected during the 11th Ala & ccedil;at & imath; Herb Festival held between March 24-27, 2022. The data obtained were analyzed with the structural equation modeling. According to the results of the study, the program, festival area, staff, souvenirs, and information dimensions of festival success factors affect festival satisfaction. The effects of convenience and food dimensions on festival satisfaction were statistically insignificant. The festival satisfaction and destination overall image variables have positive effects on destination loyalty, and the festival satisfaction variable has positive effects on the destination overall image. The destination overall images an integral partial mediating role in the relationship between festival satisfaction and destination loyalty.

    The Moderating Role Of Paternalistic Leadership In The Relationship Between Job Satisfaction And Job Stress Among Health Workers In Gaziantep, Turkey
    (WORK-A JOURNAL OF PREVENTION ASSESSMENT & REHABILITATION, 2024-12-09) Tunc, Ahmet; Yagar, Sema Dokme; Gercek, Emine; Yagar, Fedayi
    BACKGROUND: Adopting an effective leadership style is of critical importance in increasing healthcare efficiency and therefore determining patient satisfaction. For example, although there are many new and effective leadership types today, the paternalistic leadership approach can still play an effective role in developing countries. OBJECTIVE: The aim of this study is to examine the moderating role of paternalistic leadership in the relationship between job satisfaction and job stress. METHODS: A total of 466 healthcare workers completed measures of perceived paternalistic leadership, job stress, and job satisfaction. The research was conducted in the center of Gaziantep, one of the largest cities in Turkey. Regression analysis was used to evaluate the moderate variable. Dawson slope were used to visualize the results. RESULTS: A negative relationship was found between job satisfaction and job stress. Additionally, it has been determined that the perception of paternalistic leadership has a moderating role. It has been observed that as the perception of paternalistic leadership increases, the negative relationship between job satisfaction and job stress decreases. CONCLUSION: It has been concluded that the paternalistic leadership approach can play a critical role in increasing the productivity of healthcare workers and reducing the negative effect of stress on satisfaction. It has been suggested that policies be developed to develop appropriate strategies for creating work environments that will increase employees' perceptions of paternalistic leadership.

    Wage inequality, skill-specific unemployment and trade liberalization
    (2020) Koymen-Ozer, Seda
    Labour market outcomes of trade liberalization are at the heart of the policy debate. In this model, the long-run effects of trade liberalization and trade-induced skill-biased technological change on wage inequality and unemployment are studied by augmenting a heterogeneous firm trade model with job search and unemployment. In the model, there are two types of workers-skilledandunskilled-and two types of technologies-lowandhigh. Firms draw their productivities from a common distribution and, conditional on their productivity, decide on the entry, export and type of technology. Then they post the optimal number of vacancies and engage in individual wage bargaining with workers. In the case of two symmetric partners, trade liberalization leads more firms to enter foreign markets while leading the least-productive firms to exit. Moreover, with lower technology-adoption costs and/or a higher initial level of liberalization, more firms upgrade their technology after a reduction in variable trade cost. The redistribution of market shares toward more-productive firms increases the demand for both skilled and unskilled workers. This, in turn, raises wages and reduces unemployment rates for both types of workers. Nevertheless, trade liberalization has asymmetric wage effects on workers: it increases wage inequality in favour of skilled workers. Further, the unemployment rate in the skilled labour market falls to a greater extent, implying a change in the skill composition of unemployed workers in both trade partners. Resume Inegalite salariale, chomage lie aux competences specialisees et liberalisation. Les consequences de la liberalisation des echanges sur le marche du travail sont au c oe ur du debat politique. Dans ce modele, nous etudions les effets a long terme de la liberalisation des echanges et des evolutions technologiques induites par le commerce, lesquelles favorisant les competences specialisees, a la fois sur les inegalites salariales et le chomage. A cette fin, nous avons augmente un modele commercial d'entreprises heterogenes en y ajoutant la recherche d'emploi et l'inactivite professionnelle. Dans ce modele, nous nous appuyons sur deux types de travailleurs, les travailleurs qualifies et non qualifies, et sur deux types de technologies, les technologies rudimentaires et les hautes technologies. Les entreprises tirent leur productivite d'une distribution commune, et en fonction de cette meme productivite, peuvent decider de l'introduction, de l'exportation et du type de technologie. Ensuite, ces entreprises proposent un nombre optimal d'emplois a pourvoir et s'engagent dans une negociation salariale individuelle avec les travailleurs. Dans le cas de deux partenaires symetriques, la liberalisation des echanges conduit davantage d'entreprises a integrer les marches etrangers tout en poussant les moins productives a en sortir. De plus, avec des couts d'adoption technologiques plus faibles et/ou avec un niveau de liberalisation initial plus eleve, de plus en plus d'entreprises modernisent leur technologie apres avoir reduit leurs couts commerciaux variables. La redistribution des parts de marche vers les entreprises les plus productives provoque une augmentation de la demande de travailleurs qualifies et non qualifies. Par voie de consequence, les salaires augmentent et le taux de chomage diminue pour les deux types de travailleurs. Neanmoins, la liberalisation des echanges engendre un effet asymetrique quant au salaire des travailleurs car elle augmente les inegalites salariales en faveur des travailleurs les plus qualifies. De plus, le taux de chomage des travailleurs qualifies diminue bien davantage, modifiant ainsi la composition des competences de la main d'oe uvre des travailleurs sans emploi pour les deux partenaires commerciaux.
