Beef and milk price links in Turkey
(2013) Saghaian Sayed; Özertan Gökhan; Tekgüç Hasan
This article addresses the recent beef price spikes in Turkey, using contemporary time-series analysis. The arguments point to the impact of low milk prices that led to liquidation of dairy herds and decline of beef prices initially due to the liquidation and increased meat supply, and subsequent price increases in the next year due to decreased supply. The results revealed that dairy herd liquidation had a delayed impact of a year to 18 months on farm, wholesale, and retail beef prices, Those effects wore off over a two-year time period.

Can entrepreneurial knowledge boost the entrepreneurial intent of French students? The mediation role of behavioral antecedents
(Emerald, 2022) Alkhalaf, Taher; Durrah, Omar; Almohammad, Dawoud; Ahmed, Faisal
Purpose: Entrepreneurial knowledge occupies a significant place in policy discourse and practice, especially in developed economies. This study aims to examine the effect of entrepreneurial knowledge on the components of entrepreneurial intent of undergraduate students. The authors seek to decipher a deeper understanding of their orientation for engaging in new ventures. In addition, we analyze the mediating role of behavioral antecedents between entrepreneurial knowledge and entrepreneurial intent. Design/methodology/approach: The authors collected the primary data of 400 undergraduate students from French universities and used structural equation modeling through Smart PLS software for testing several pertinent hypotheses. Findings: The study’s results revealed that entrepreneurial knowledge negatively affects students’ attitudes in choosing entrepreneurship in favor of a corporate job. In addition, entrepreneurial knowledge does not affect the social norms and self-efficacy that shape entrepreneurial intent. Interestingly, our study also revealed no mediating role between entrepreneurial knowledge and students’ self-efficacy. Originality/value: The findings of this study will contribute to the academic discourse on the role of entrepreneurial knowledge and its potential effect in promoting entrepreneurship. Furthermore, this study has policy implications and solicits developing entrepreneurship programs to enhance entrepreneurial intent among young people.

The Cittaslow Philosophy in the Context of Sustainable Tourism Development; The Case of Turkey
(Tourism Management, 2014) Ekinci, Mehmet Behzat
This paper studies the Cittaslow (slow city) philosophy in terms of sustainable tourism development (STD); and in this context research was undertaken for the case of Turkey. Cittaslow, a movement rooted in STD philosophy, aims to encourage the development of tranquil cities already known for their historical, natural, socio-cultural, and touristic features and the intention is to offer a significant contribution to systematic and rapid implementation of STD on a global scale. This paper, which makes a particular study of the practice of STD in Turkey, offers new candidate cities (Uzungöl, Hasankeyf, Safranbolu, Ürgüp, and İznik) and, thus, endeavours to contribute to the spread of STD throughout the whole country. In this study, above-named cities were found to be particularly good candidates for Cittaslow membership. In addition to these: Tatvan, Midyat, Alanya, and Fethiye were also found to be potential Cittaslows even though they fail to meet the population criterion.

Construction labour, subcontracting and masculinity: “construction is a man’s job”
(Construction Management and Economics, 2020) Çınar, Sidar
This study examines how construction workers construct their male identity on the basis of their job requirements. A qualitative field research comprising in-depth interviews was conducted with 32 construction workers in Diyarbakır to examine subcontracting in Turkey’s construction sector. The findings show that by defining construction labour in terms of physical capacity, an outcome of the labour conditions shaped by the practice of subcontracting, construction work have become naturalised as a man’s job. The findings also illustrate how construction produces different masculinities that intersect with the understanding of working class shaped by the role of men being the head of the family rather than a single notion of manhood shaped by physical working conditions. Nevertheless, the male worker culture that feeds off different masculinities still retains the power to dominate and exclude women as workers from the construction site, e.g. through means of sexual harassment.

Determination of Women Voting Behavior: a Machine Learning Approach in the Turkish Political Arena
(Hipatia Press, 2020) Caha, Havva; Bayyurt, Nizamettin
Justice and Development Party (AKP) has been the ruling and biggest party in Turkey (AKP) since it has been established in 2002 and Republican People's Party (CHP) has been the main opposition party (CHP) since then. These two parties receive about 75% of all the votes. In Turkey half of the voters are females. In this study, the important attributes of women in party selection decisions are analyzed. To our knowledge, there is no such a study focusing on women's party preferences in Turkey. Additionally, this is one of the very few studies in Turkey concerning voters' party preferences. Therefore, this study aims to fill this gap in the literature. Center-periphery and social mobility theories are the two main theories explaining Turkish political life. The analyzed ideological, cultural, religious, social, economic and demographic characteristics of women supporters are selected according to these theories. Machine-learning techniques are employed as predictive tools. Results show that ideological attitudes like being leftist-rightist and religious values like headscarf, fasting in Ramadan, and praying are the most important effective attributes on party selection of women. However, socio-economic, cultural, educational and demographic atributes are not effective on party selection of women in Turkey.

Effect of Economic Policy Uncertainty on Co2 With the Discrimination of Renewable and Non Renewable Energy Consumption
(Pergamon Elsevier Science Ltd, 2024) Aslan, Alper; Ilhan, Ozturk; Usama, Al-Mulali; Savranlar, Buket; Polat, Melike Atay; Metawa, Noura; Raboshuk, Alina
The link between policy -related economic uncertainty and the environment has a new and developing literature. In this study, the effects of economic policy uncertainty, energy consumption and economic growth on pollution in G7 countries are investigated by using methods of moments quantile regression over the perod of 1995-2018. According to the long run coefficient estimation results, in the model in which the fossil fuel energy consumption variable is used as an energy consumption indicator, economic policy uncertainty has a reducing effect on emissions at all quantile levels. Although this negative effect becomes more pronounced as the quantile level increases, it is statistically insignificant at the 0.90 quantile level. In the model that includes fossil fuel energy consumption, the coefficient of economic policy uncertainty variable is negative in all quantiles and is significant only at the 0.30 and 0.40 quantile levels. In addition, while a U-shaped relationship is detected between economic growth and emissions in these countries, the destroying effect of fossil fuel energy on environmental quality is confirmed in all quantiles. Thus, it should be a priority to support the developments in growth performance with environmental regulations, encourage energy -saving and energy -efficient practices as well as to establish the legal infrastructure.

Entrepreneurship in Crisis: The Determinants of Syrian Refugees' Entrepreneurial Intentions in Turkey
(Sustainability, 2021) Dawoud, Almohammad; Omar, Durrah; Taher, Alkhalaf; Mohamad, Rashid
This study aims to identify the determinants of entrepreneurial intentions among Syrian refugees in Turkey. The research, based on planned behaviour theory, focused on the impact of the refugee context on those intentions and thus on the attitudes and behaviour of entrepreneurs. The study is based on the positivist paradigm, and a quantitative methodology was used to collect data. We preferred the method of convenience sampling and chose 122 entrepreneurial projects at the beginning of 2020. The results show that psychological characteristics have no significant impact. Motivation, conviction, and independence are not sufficient conditions for the choice of an entrepreneurial profession. Self-standards do not affect the entrepreneurial intentions of refugees, as support from family and friends may not be sufficient reason to engage in an entrepreneurial project. However, entrepreneurship emerged among the refugees distinguished by perseverance, efficiency, a spirit of innovation, prior experience, adequate perceptions of barriers, and having the resources needed to implement projects. The refugee context has a negative emotional impact on entrepreneurship for reasons related to conditions of instability, language difficulties, the need for capital to invest, and a lack of entrepreneurial knowledge. The research findings can be used to support the role of humanitarian organisations, UN agencies, and host governments in developing a deeper understanding of entrepreneurial intentions in the refugee context. © 2021 by the authors.

Evaluation Of The Relationship Between Foreign Trade Liberalization And Unemployment Within The Framework Of The Heterogeneous Firm Model;
(Sosyoekonomi Soc, 2022) Cirkin, Zeynep; Goksel, Turkmen
This study investigates how foreign trade liberalization affects unemployment by using the Melitz model (2003), which is one of the intra-industry trade models expressing trade between countries with similar technologies, preferences, and cost structures that make up a large part of international trade. The Melitz model (2003) is remodelled by efficiency wage theory to endogenize unemployment. The model is solved by numerical method. It is assumed that market expansion and competition in the market occur simultaneously. The effect of liberalization on unemployment varies depending on which of two factors, market expansion or competition, dominates the other. According to the results, unemployment decreases when market expansion dominates the competition, while unemployment increases if competition dominates market expansion. In addition, it has been observed that there is an increase in the total amount of production, productivity, and unemployment insurance when market expansion is dominant. Also, it has been observed that there is a decrease in the total amount of production, productivity level, and unemployment insurance when competition in the market is dominant.
Evidence From Turkish and Syrian People for the Measurement Invariance of the Cbbe Scale and Clues for the Distribution Strategies of the Brands
(Kodisa Foundation, 2023) Kayaoglu, Ahmet; Gulmez, Yavuz Selim
Purpose: This research aims to test the measurement invariance of the consumer-based brand equity scale on Turkish and Syrian university students who live together but are from different cultural groups. Research design, data, and methodology: The consumer- based brand equity scale developed by Buil et al. (2008) is applied to the participants. In testing the consumer-based brand equity scale, the Netflix brand, which is considered well-known by both cultural groups, is preferred. It is thought that choosing an internationally recognized brand would facilitate the conduct of this research. Structural invariance and measurement invariance are tested using structural equation modeling. Results: The consumer-based brand equity scale has measurement invariance on Turkish and Syrian university students. Therefore, it has been revealed that the responses of participants from both cultures regarding the Netflix brand are comparable. Conclusion: The findings of the study provide clues for practitioners to review their distribution strategies. As a matter of fact, cultural studies conducted in different countries are common. Still, the originality of this study is ensured by the profile of participants who live in the same country but come from different countries.

GENDER EFFECT IN EXPLAINING MOBILITY PATTERNS IN THE LABOR MARKET: A CASE STUDY OF TURKEY
(WILEY, 2014) Eryar, Değer; Tekgüç, Hasan
This paper examines the importance of gender for different job mobility patterns using an extensive household survey data from zmir, the third largest city in Turkey. The determinants of job-to-job and job-to-nonemployment transitions are analyzed with the help of a multinomial logit estimation method. The results indicate that there is a distinction regarding the probability of job mobility patterns based on gender. It is more likely for women to be engaged in job-to-nonemployment transition, whereas men tend to change jobs more often. Although gender plays a significant role in job mobility patterns, traditionally imposed social constraints associated with childcare and household duties provide us with mixed results considering the behavior of women in the job market. On the other hand, having highly paid and secure jobs decreases the probability of both patterns of job mobility.

Impact of fossil fuels and renewable energy consumption on economic growth in Paris Club Countries
(AIP Publishing, 2022) Öztürk, İlhan; Öztürk, İlhan; Aslan, Alper; Özsolak, Baki; Atay Polat, Melike; Turan, Zubeyir
The relationship between economic growth (in terms of GDP) and renewable energy (RE) and nonrenewable energy (NRE) consumption was investigated in 20 countries featured on the Renewable Energy Country Attractiveness Index list, also known as the Paris Club. The effect of both RE and NRE consumption on economic growth is discussed in the growth model based on the neoclassical production function. Labor and capital, which are important dynamics of growth, are also considered in the model. Granger causality and panel vector autoregression analysis are performed for the period 1991–2016. The results show that neither RE nor NRE consumption has a positive effect on economic growth. In reality, a 1% increase in RE consumption will reduce the GDP growth by 0.14%. For the effect of GDP growth on energy types, if growth increases by 1%, NRE consumption increases by 5.54%. If economic growth increases by 1%, a reduction of 1.73% occurs in RE consumption. In contrast, a causal link between both types of energy to growth has not been determined. There is no statistically significant coefficient of NRE and capital factors on GDP. A mutually positive and statistically significant relationship was determined between labor and growth. According to the results of variance decomposition, the basic dynamic of growth is itself: over a ten-year period, growth was affected by itself by 98%.

The impact of technological innovations on the environmental Kuznets curve: evidence from EU-27
(Springer, 2024) Ercan, Hamdi; Savranlar, Buket; Atay Polat, Melike; Yiğit, Yüksel; Aslan, Alper
The EKC hypothesis expresses the inverted U-shaped relationship between per capita income and environmental quality. In the literature, the role of technological innovations and income inequality on pollution is a relatively recent discussion in the studies testing the EKC hypothesis. The aim of this paper is to investigate the impact of technological innovations, income inequality, exports, urbanization, and growth on CO2 emissions in EU-27. In addition, while investigating this relationship, exports and urbanization are also considered and panel vector autoregression (PVAR) analysis is applied for the 2005-2019 period. According to the coefficient estimation results, while income inequality, exports, and urbanization increase pollution, technological innovations contribute to environmental quality. Also, the results demonstrated that the EKC hypothesis is invalid in these countries and there is a U-shaped relationship between growth and emissions. The causality test results revealed the presence of unidirectional causality running from all explanatory variables to CO2 emissions. Moreover, impulse-response graphs demonstrated that the reply of emissions to the shocks in the explanatory variables is similar to the long-run coefficient results. In conclusion, all available empirical evidence for this relationship highlights that income inequality and technological innovations should be considered in policy-making processes to ensure environmental quality in EU-27 countries.

International Efforts Against Impunity for the Use of Chemical Weapons in Syria Is There Hope for International Justice?
(Journal of International Criminal Justice, 2022) Aloklah, Wissam Aldien
This article examines international developments in the investigation of incidents involving the use of chemical weapons (CWs) in Syria between 2012 and 2021. Specifically, it analyses the measures adopted by the Organization for the Prohibition of Chemical Weapons (OPCW) in cooperation with the United Nations, and the progress in eliminating the Syrian chemical weapons programme. The article further addresses the international community's responses to the use of CWs in Syria from the perspective of international law, and its inability to hold those responsible accountable and to offer redress the victims. Such inability is illustrated by the somewhat weak action following two reports of the Investigation and Identification Team of the OPCW, which clearly indicated that the authorities of the Syrian Arab Republic are behind a number of CW attacks in Syria. The article argues that the lack of international justice, despite clear evidence of blatant violations, is rooted in the fundamental differences between major powers within the Security Council, as well as in the existing gaps in the law.

Investigation of the Sensitivity of EU Countries to Temperature Anomalies in Terms of Economic and Technological Indicators
(SpringerLink, 2023) Atay Polat, Melike; Alper Aslan, Buket Altinoz, Melike Atay Polat
In this study, the interrelationships between global climate change and EU countries’ GDP, investments, R&D expenditures, innovations, and labor productivity indicators are discussed. Global temperature anomalies are adopted as an indicator of climate change and the relationsgip estimated with the panel vector autoregreesion (PVAR) approach for the period from 1996 to 2018. Results suggest that an increase in atmospheric temperature has negative efect on economic growth, investment, and labor productivity. However, an increase in atmospheric tempetrature increases patent applications by 0.4% in the long run. Moreover, while economic growth and investments trigger temperature anomalies, labor productivity has a negative efect on atmospheric temperature. The long-run coefcient estimation results are confrmed by analysis, and the existence of strong dynamic relationships between the variables is determined. Impulse–response graphs difer from these results and emphasize that the efects caused by shocks should be considered temperature anomalies and EU’s technological and economic developments.

Is electronic finance sustainable or not in the European Union? New insights from the panel vector autoregression approach
(SpringerLink, 2022) Altınöz, Buket; Aslan, Alper; Atay Polat, Melike; Topalgokcelli, Emre; Esmeray, Murat
Abstract Today, as a result of the developments and widespread use of information and communication technologies, the weight of online shopping in the economy has increased. The environmental impacts of this new order, which is an important part of electronic fnance, are discussed. In this study, the efect of electronic fnance, economic growth, renewable energy consumption, and urbanization on emissions in EU member countries is examined using the panel vector autoregression (PVAR) approach for the period from 2005 to 2018. The main results suggest that e-fnance has a positive and statistically signifcant efect on CO2 emissions. However, the renewable energy consumption-increasing efect of e-fnance is greater than its emission-reducing efect. Moreover, renewable energy consumption has a statistically insignifcant efect on emissions. Therefore, the contribution of e-fnance on environmental quality weakens. The requirement for EU member countries to prioritize the use of environmentally friendly energy to beneft from the environmental contribution of e-fnance in the most optimal way is stated as the main policy implication of this study

Mathematical model and a variable neighborhood search algorithm for mixed-model robotic two-sided assembly line balancing problems with sequence-dependent setup times
(SpringerLink, 2022) Aslan, Şehmus
Human labor is generally being replaced with robots for high automation, increased fexibility, and reduced costs in modern industry. Few studies consider the sequencedependent setup times in the assembly line balancing literature. However, it should not be overlooked in a real-life setting. This article presents a new mathematical model and variable neighborhood search (VNS) algorithm for mixed-model robotic two-sided assembly line balancing, with the aim of minimizing the cycle time by considering the sequence-dependent setup times. The efectiveness of the proposed VNS is tested with a set of test problems from the literature. The computational results and statistical analysis indicate that the proposed method yields promising results.
Misspecified Expectations in an Open Economy
(Elsevier, 2024) Yilmaz, Yusuf Omur; Cicekci, Cumhur
In the past two decades, Turkey has experienced multiple changes in its monetary policy regime.To analyse how these policy changes affect the behaviours of households and firms, somebehavioural parameters are incorporated into a small open economy New Keynesian model. Ourapproach consists of four phases. First, we assess the impacts of the behavioural parameters onthe model and find that higher values of the parameters increase the effects of expectationson the model. Second, for the period between 2006 and 2021, the model is estimated for theTurkish economy and the findings show that both households and firms are more forward-looking in their decision making. Moreover, the current variables have a weak effect on thenominal interest rate, and the inertial nominal interest rate has a strong effect on it. Third, weanalyse the evolution of the model parameters over the period and find that the behaviouralparameters tend to increase, while the monetary policy becomes more inertial. Finally, weconclude that the Central Bank should follow Domestic Inflation-based Taylor rule to minimise welfare loss
