This study examines the magnitude, timing, and persistence of export gains from Turkey’s regional trade agreements (RTAs), addressing why previous studies found null effects despite extensive preferential liberalization. A structural gravity framework analyzes Turkey’s bilateral exports to over 160 partners (1996–2020) using PPML estimation with country-pair fixed effects. Dynamic RTA indicators capture anticipation and phased-in effects over twelve years, while time-varying border coefficients isolate policy effects from globalization trends. RTAs generate large, persistent export gains that accumulate gradually rather than immediately. Cumulative effects reach 815 percent over twelve years without globalization controls, or 102 percent when secular trends are absorbed, both of which are economically substantial. The absence of anticipation effects validates causal interpretation. Trade agreements function as medium- to long-term integration instruments. Policy continuity and complementary domestic reforms amplify RTA benefits. This study provides the first comprehensive dynamic assessment of Turkey’s RTA effects within a structural gravity framework, resolving puzzling null findings from earlier specifications and establishing bounds on policy-attributable export gains.

This study mainly aimed to examine the impact of university students' purchasing tendency from e-commerce sites and demographic characteristics on student satisfaction through the example of a leading foundation research university in Türkiye. In the study, it was investigated whether there was a significant difference between students' purchasing tendencies from e-commerce sites and student satisfaction. It was also investigated whether there was a significant difference between demographic characteristics and student satisfaction. Methodologically, a descriptive online survey method including a questionnaire was applied to collect data. The survey was responded by 240 randomly selected students. The data were analyzed with SPSS-26. The study concluded that there was no significant difference between the average daily time spent on the internet and the type of device used to connect to e-commerce sites, which are among the criteria reflecting the tendency to purchase from e-commerce sites, and student satisfaction whereas there was a significant difference between the number of products purchased through e-commerce sites and student satisfaction. Furthermore, it was revealed that there was no significant difference between demographic characteristics such as gender, marital status, education and monthly income and student satisfaction, whereas there was a significant difference between age and student satisfaction. Accordingly, it was indicated that the difference in terms of age was especially in favor of students in the 22-25 age group. It is thought that the study will contribute to the literature by examining the impact of university students' purchasing tendency from e-commerce sites and demographic characteristics on student satisfaction, together with the example of a leading foundation research university. The study is limited by the selected sample foundation research university, the number of students responded, survey questions-answers, the applied statistical analysis methods and tests. Therefore, in order to reach more general results, it is suggested to expand the studies with more diverse and larger numbers of foundation research universities, students, survey questions and statistical methods.

This study mainly aimed to examine the impact of the COSO’s internal control system components (Control Environment, Risk Assessment, Control Activities, Information-Communication, Monitoring) on corporate governance principles (justice, transparency, accountability and responsibility) through the example of a leading educational foundation in Türkiye. In the study, it was investigated whether there was a significant relationship between the perceptions of employees regarding the effects of the internal control system components on corporate governance. It was also investigated whether these perceptions differed according to demographic characteristics such as gender, age, education, length of service, position. Methodologically, a descriptive online survey method including a questionnaire was applied to collect data. The survey was sent to 234 participants in different departments and positions working in the foundation, and 197 employees responded. The data were analyzed with SPSS-22. The survey, which was suitable for a 5-point Likert scale, included statements regarding demographic characteristics and COSO’s main internal control components and corporate governance principles. The study concluded that all COSO components have a significant and positive relationship with corporate governance principles. In addition, a stronger relationship was revealed between transparency and accountability principles and internal control components compared to others. Furthermore, it was indicated that these perceptions differed according to demographic characteristics. While significant differences were found in perceptions according to demographic characteristics such as gender, age and position, no differences were found according to education and working years criteria. The study is considered to contribute to the literature because it is the first study to examine the impact of the main COSO internal control components on corporate governance principles, together with the example of a leading educational foundation. The study is limited by the selected sample educational foundation, the number of respondents, survey questions-answers, the applied statistical analysis method and tests. Therefore, in order to reach more general results, it is suggested to expand the studies with more diverse and larger numbers of educational foundations, employees, survey questions and statistical methods.

The study examines concerns regarding Islamic finance legislation in Ethiopia. Using a qualitative method, the study investigated the current legal and regulatory frameworks regarding Islamic finance and the challenges facing Islamic financial institutions in the country. In the study we conducted semi-structured interviews with 23 respondents, including executives, boards of directors, regulators, managers, shariah board members, and legal scholars familiar with the country's laws. The study's findings indicate an urgent necessity for an inclusive and robust legal structure specifically designed for the unique characteristics of Islamic financing. Enhanced supervisory oversight is essential for ensuring adherence to Sharia principles. Furthermore, the research findings demonstrate how important it is to set up a separate supervisory body within the National Bank of Ethiopia to keep an eye on Islamic financial institutions. Lastly, the study highlights the significance of having qualified professionals and Sharia scholars in Islamic financing. Integrating Islamic finance education into universities can enhance capacity-building for regulators, scholars, and finance professionals.

The findings underscore the significance of institutional stability and macro-financial predictability in maintaining export performance in volatile emerging economies. Enhancing regulatory quality, bolstering macro-financial stability, and augmenting enterprises' capacity to manage risk will facilitate more robust export results. Incorporating institutional and financial frictions directly into gravity models offers a more accurate framework for policy assessment. This research employs a structural gravity model, estimated using Poisson pseudo maximum likelihood, to analyse Turkey's bilateral export flows to 164 partner nations from 1996 to 2020. Political stability and exchange rate volatility are integrated as time-varying institutional and financial frictions. Indices of economic scale, geographical distance, and remoteness are incorporated to maintain alignment with structural gravity theory. The political stability of destination nations is a crucial positive factor influencing Turkish exports and signifies the existence of a governance premium. Exchange rate fluctuation exerts a sustained adverse impact, diminishing the anticipated advantages of nominal depreciation. Visual data indicates two consistent behavioural tendencies. Exporters are increasingly venturing into politically risky countries; yet, long-term export growth is constrained by institutional inertia and robust network dependencies. The findings indicate that institutional reliability and macro-financial predictability are crucial for maintaining export performance in volatile emerging economies. Enhanced regulatory quality, greater macro-financial stability, and superior firm-level risk management are essential for achieving more resilient export outcomes. Incorporating institutional and financial frictions directly into gravity models offers a more accurate framework for comprehending trade dynamics and formulating effective policies.

In the pursuit of academic excellence, scholars are dependent on trustworthy journals to disseminate their research and contribute to the collective body of knowledge. However, the academic community is not immune to deceptive practices. This letter highlights the case of the "Global International Journal of Innovative Research," where my name, along with esteemed colleagues, was falsely associated with the editorial board without consent. Despite repeated efforts to address this issue, the journal remains unresponsive. This letter announces our intention to publish an exposé article, meticulously uncovering the fraudulent practices of the journal and its publisher. A subsequent public statement aims to warn the academic community about the deceptive nature of the "Global International Journal of Innovative Research" and emphasizes the collective responsibility of scholars to uphold ethical publishing standards. Through this exposé, we hope to safeguard the integrity of academic pursuit and raise awareness about the risks associated with engaging with predatory journals.

In the past 20 years, commodity markets have been examined under the hypothesis of whether the prices exhibit recurrent patterns or follow the stochastic processes. In this study, we analyze both global energy markets and food markets to detect the presence of multiple equilibria, which may lead to higher spikes in prices and to the occurrence of intermittency. This study focuses on daily prices in Brent petrol and Natural gas markets from 23 May 2017 to 23 May 2022. This time interval covers the period where extraordinary economic and financial policies have been preferred in countries worldwide amid the Covid-19 pandemic crisis. On the other hand, the study investigates global Food index monthly data from 2007M11 to 2022M4. Similarly, the time interval under examination points out the effects of the 2008 global crisis where expansionary monetary policies have been implemented both by the Federal Reserve of the U.S and the European Central Bank. We employed the phase-space reconstruction method for the Crude oil Brent Europe and spot Natural gas prices series, and global Food index data respectively. The main findings of the study demonstrate that commodity markets do not converge to a unique equilibrium level, instead multiple equilibria persist and chaotic behavior occurs. The presence of multiple equilibria leads to an increase in complexity and recurrently causes volatility in commodity markets, which may have spillover effects on other financial markets. Our results suggest that these effects simultaneously increase global inflationary pressures. From the perspective of policy making, it is crucial to establish a strategy to eliminate multiple equilibria and prevent high price spikes. Our findings have important implications for Central bank policies in emerging markets and portfolio and risk management.

This paper aims to investigate the mediating role of explicit knowledge sharing in the relationship between empowering leadership and proactive work behavior in defense industry enterprises. The sample of this study consists of defense industry enterprises operating within the borders of Turkey. A total of 305 survey data were collected from these enterprises using the random sampling method, and 5 survey data among them were eliminated because of missing information, and analyzes were made with a total of 301 survey data. Structural equation modeling was used to test the research model and hypotheses. According to the analysis results of the study, empowering leadership has a positive effect on proactive work behavior and explicit knowledge sharing. In addition, it has been understood that open information sharing has a positive effect on proactive work behavior. Finally, it has been revealed that explicit knowledge sharing has a mediating role in the relationship between empowering leadership and proactive work behavior.

The rapid growth in civil aviation operations in recent years has raised expectations from flight attendants. Their duties have been intensified, and flight attendants have become subject to physical and mental fatigue due to irregular sleep, inadequate rest time, and long working hours. This study investigates the causes and effects of fatigue among flight attendants of a Turkish airline company through a self-administrated questionnaire. The survey is run online by 152 flight attendants. The results show that flight attendants have trouble falling asleep before flight duty. Before night flights and during layovers, the sleep duration is dramatically low. The results also reveal that factors related to scheduling, i.e., long duty days, night flights, and consecutive working days, play an essential role in fatigue. Thus, airline companies should revise their scheduling practices. In balancing work and social life, men struggle more than women, and married flight attendants have more difficulty than single ones. The findings provide valuable insights for airline companies and policymakers to seriously manage fatigue-related factors to ensure the safety of aviation operations and the well-being of flight attendants.

The Covid-19 pandemic has created a disadvantaged student population due to the sudden obligation for distance learning. Poor performance of online educational tools, risk of transmission and staying at home cause stress and anxiety in students. This research examines the effects of usability and accessibility of the online learning system on students’ anxiety in presence of students’ perceived social support as well as students’ perceived optimistic/pessimistic life orientation. The survey instrument prepared for this purpose includes questions about the online learning system used, Covid-19 anxiety, life orientation and perceived social support. Web-based questionnaires were collected from 5,682 students from different universities and the data was analyzed for the role of social support and life orientation on anxiety caused by stress born of distance learning. Findings show that accessibility has a negative effect on anxiety while the effect of perceived social support on access problems could not be ascertained. It was determined that the optimism dimension had a moderating effect on students’ anxiety and the pessimism dimension had a mediating effect. The research results are consistent with the literature.

This paper aims to examine the impact of Covid-19 pandemic on stock markets. This paper also analyses the stock market cointegration of selected global equity indices that performed better and have a quick speed of recovery during the pandemic. This paper also questions how increasing uncertainty and volatility deters investors’ perception of the diversification of equity investments. The dataset for the selected 12 global equity indices has been used from Thompson Reuters’s EIKON database in a given period of time between 2010 and 2021. This paper employs Vector Error Correction Models to assess the relationship among the selected global equity indices. Findings demonstrate that (i) there is an adverse impact of Covid-19 on the Global Equity markets, (ii) there is a clear sign of cointegration in global equity indices, (ii) investors can benefit from investing in particular equity indices that have exhibited quick speed of recovery from the pandemic records lows. The findings finally provide a strong foundation for constructing a resilient equity portfolio in a highly uncertain market environment.

This paper aims to examine the impact of mobile telecom service characteristics on consumer satisfaction in urban Uganda, using a Servqual model. The association between customer satisfaction level and service quality characteristics has been tested with a regression analysis. In this study, assurance as a Servqual dimension has been substituted with tariffs to exhibit its effect on customers’ satisfaction levels. Findings verified that some of the Servqual dimensions including reliability, empathy, and responsiveness have been positively affecting the customer satisfaction level in the Ugandan context. The study also demonstrated that the prices of products and services of telecom companies were not the major concerns for telecom consumers in Uganda. The study, finally, provides some practical guidelines to managers of telecom companies as well as hinting out which Servqual dimensions are valued most by customers in Uganda.

The Turkish social insurance system has been feverishly debated for years, particularly through its burden on the economy. The most recent reform is an attempt to neutralize the deterioration within the social security system and its effects on the economy. After the recent reform, ‘the way that retirement benefits are calculated’ is changed unfavorably for workers and the minimum age for retirement is increased. In particular, for an agent with 25 years of social security tax payments, the replacement rate is down from 65 percent to 50 percent. On the other hand, retirement age is up from 60 to 65. The aim of this paper is to investigate the macroeconomic effects of these changes using an OLG model. The author’s findings indicate that labor supply, output and capital stock increase when changes above are applied to the benchmark economy calibrated to the Turkish economy data in 2005. A critical change with the current reform is that the marginal benefit of working has become uniform over ages. In a simulation exercise, the marginal retirement benefit in the benchmark economy is changed to be uniform over ages while keeping the size of social security system unchanged. As a result, the benefit of retiring at a later period increases. However, uniform distribution of the marginal benefits itself decreases both the capital stock and output of the economy. Increasing the retirement age has positive effects on the economy since agents obtain retirement benefits for fewer years and at an older age.

The purpose of this study is to investigate the impact of stock splits on the return, riskiness, and liquidity of stocks. Utilizing a sample of 94 stock splits taken place between 2010 and 2019 at Borsa Istanbul, the study analyzes the daily abnormal returns, change in volatility, and changes in volume around the stock split announcement and execution dates. The results display significant positive abnormal returns around the announcement date but not significant abnormal returns around the execution. The volatility and liquidity of stocks increase significantly around both announcement and execution dates. The findings are in line with the positive signaling, and liquidity hypotheses of stock split and with most of the observations reported in the empirical literature. The new evidence provided points out the lack of semi-strong form of market efficiency at Borsa Istanbul as far as the stock splits are considered.

 The purpose of this exploratory study has been to provide insight into the success factors of ECF campaigns and, in particular, explore the role of trust. In specific, the research questions for this study are: (1) What dimensions of ECF success have been studied so far, and (2) is there any established literature on sustainability, blockchain technology and trust in the realm of ECF.  To that end, a systematic literature review is conducted by investigating ISI Web of Science and Scopus, two major academic databases, through relevant keyword combinations. The theoretical framework relies on signaling, legitimacy and stakeholder theories. Findings indicate that the role of trust is an emerging theme, and sustainability and BT in relation to trust, to the best of the author’s knowledge, is not yet focused upon in crowdfunding research. This study contributes to the literature of crowdfunding and entrepreneurship.

As Covid-19 lockdown forced firms to organize work differently, for example, managing people remotely.  Despite the benefits may a firm obtain in adopting new business tools like remote management, but providing assurance that internal control function in an efficient manner is important for a firm; that is because there is a growing interest in internal control issues. It is very important to determine how the remote working model, which emerged during the Covid 19 pandemic process, has changed the accounting processes of businesses. The aim of this study is to propose an internal control model under factors such as remote management, risk assessment, control activities, information and communication, and observation. The data in the research were obtained from the experts in our sample by using the survey method. Our sample consists of managers, supervisors, and academics. The data obtained were evaluated with the Smart-PLS version 3.2.9 program. Findings highlight a positive relationship between control activities and remote management.  

Toxic leadership refers to the sum of the negative aspects of leaders within their leadership traits. Narcissistic leadership is a multidimensional structure that includes charismatic leadership and authoritarian leadership types. Toxic leaders can harm the organization, employees, and society in which they work. This research aims to determine the toxic characteristics of leaders working in public universities and to extract the attribute of organizational trust in job satisfaction. Turkey's Istanbul made the data collected through face-to-face survey research methods in 470 people working in the public university hospital in the province were analyzed by analysis methods used in social sciences. As a result of the analysis, a negative significant relationship between toxic leadership and organizational trust, a negative significant relationship between toxic leadership and job satisfaction and its sub-dimensions, and a positive significant relationship between organizational trust and job satisfaction and its sub-dimensions were found. Toxic leadership affects managerial job satisfaction and company policy-based job satisfaction through the full set of organizational trust. In addition, toxic leadership has also been found to be effective on job satisfaction arising from employees through partial organizational trust

In this study, the fear created by the Covid-19 global epidemic on consumers (general fear of viruses and fear of activity), spending (cleaning products, preventive health products, fresh and organic food and vitamin/mineral support, clothing, education, home purchasing, vehicle, loan. The relationship between buying, rental, fashion, vacation, travel, entertainment, electronics, home decor/furniture, mobile phone, activity and general) and savings have been tested. For this purpose, in order to test the relationship between fear, saving, and spending during the Covid-19 pandemic process, a Likert-scale online survey link was shared on social networks (Twitter, LinkedIn). The total of 385 surveys was analyzed using Google Form and SPSS program (Anova, Regression). As a result of the analysis, fear (general fear and fear of activity), spending (education, vehicles/cars, monopoly products, and tobacco products, games of chance, home buying and renting, loans, luxury/fashion, games, and toys, vitamins, minerals, and food support, public services, home, and furniture décor, electronic products (including mobile phones) expenditures remained the same, protective healthcare products, cleaning products, fresh and organic food expenditures increased, travel, public transportation expenditures decreased, holiday and entertainment expenditures decreased significantly). In the research, it was determined that 42% of the participants increased their savings by 30.5% slightly, and the amount of savings did not change at all for 27% of the participants. According to the results, as consumers' fear of Covid-19 increases, some spending categories (health products, cleaning products, fresh and organic food spending) and savings rate increase. In addition, it was observed that 90% of the participants canceled their expenses due to Covid-19. As a result of the research, significant relationships were found between the variables of fear, saving, and spending during the Covid-19 pandemic process.

  This study examines the relationship between organizational justice and organizational ambidexterity with organizational learning. This paper also evaluates the effect of organizational justice on organizational learning strategies of employees in the cause-effect relationship and measure the effect of perceived organizational support and bi-directionality on organizational learning. 645 family firms operating in Istanbul have been analyzed with Structural Equation Model. Findings demonstrate that organization's ambidexterity ability and the concept of justice in the organization had an indirect and positive effect on the perception of organizational support. This study also highlights that companies using their generic knowledge and skills increase the effectiveness of their innovation activities. The exploratory and development capabilities of a company make a significant contribution to the personal development of the employees in the company.

This study examines the effects of the effectiveness of the internal control system (ICS) on crisis management skills (before, during, and after the crisis) in the event of a disaster through the Istanbul Metropolitan Municipality (IMM) Fire Service Department.   Methodologically, a comprehensive survey questionnaire was used to collect data from 251 workers of the IMM fire service department located on the Anatolian side of Istanbul. Statistic Package for Social Sciences (SPSS) version 22 used to analyze data by running among other reliability tests, T-Test, ANOVA, and Regression analysis.  The results of the study indicated that ICS of the Fire Service Department of IMM showed high levels of effectiveness in the event of a disaster and that the institution has a high level of crisis management skills. In addition, the study found that a high positive relationship existed between ICS and Crisis Management Skills of the IMM fire service department before, during, and after the crisis in the event of a disaster. Finally, the study revealed that, ICS has a positive and high impact on IMM crisis management skills before, during, and after the crisis, and that the effectiveness of ICS had increased the crisis management skills of the institution.
