Beef and milk price links in Turkey
(2013) Tekgüç, Hasan; Özertan Gökhan; Tekgüç Hasan; Department of Economics / İktisat Bölümü
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.

The Cittaslow Philosophy in the Context of Sustainable Tourism Development; The Case of Turkey
(Tourism Management, 2014) Ekinci, Mehmet Behzat; Department of Economics / İktisat Bölümü
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; Department of Economics / İktisat Bölümü
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 Editorial, 2020) Çaha, H.; Bayyurt, N.
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. © 2020, Hipatia Editorial. All rights reserved.

(2022) Doru, Ömer; Örsan Özer; Department of Economics / İktisat Bölümü
Purpose: It is to empirically examine the factors affecting intraindustry trade in the automotive sector between Turkey and 24 OECD member trade partners. Design/Methodology: The determinants of intra-industry trade were tested with panel data analysis in the automotive sector. As a result of the test carried out to determine the model, regression analysis was performed with the Driscoll-Kraay standard error estimation method. Findings: The variables market size, development level, and trade openness have a positive impact on intra-industrial trade, while the variables market size difference, income inequality, and geographical distance have a reverse impact on intra-industry trade. Bulgular: Piyasa büyüklüğü, kalkınma düzeyi ve dışa açıklık değişkenleri endüstri içi ticareti pozitif yönde; piyasa büyüklüğü farkı, kalkınma düzeyi farkı ve coğrafi uzaklık değişkenleri ise endüstri içi ticareti zıt yönde etkilemektedir. Limitations: Export and import data for 2003–2019 are used in international trade figures in the 3-digit Standard International Trade Classification, SITC Revision-3. Originality/Value: Empirical application on the factors affecting intra-industry trade in the Turkish automotive sector is considered to be important and different in terms of subject.

Effect of Economic Policy Uncertainty on Co2 With the Discrimination of Renewable and Non Renewable Energy Consumption
(Pergamon-elsevier Science Ltd, 2024) Atay Polat, Melike; Ilhan, Ozturk; Usama, Al-Mulali; Savranlar, Buket; Polat, Melike Atay; Metawa, Noura; Raboshuk, Alina; Department of Economics / İktisat Bölümü
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.
The Effects of Climate Change on the Agriculture Sector of Mardin Province: A Qualitive Research
(2022) Acıbuca, Veysi; Çuhadar, Pınar; Atay Polat, Melike; Department of Organic Agriculture / Organik Tarım Bölümü; Department of Economics / İktisat Bölümü
This study aims to examine the effects of climate change on Mardin where both the arable land and livestock are high and the agriculture-based industry is developed and to realize perspectives of these stakeholders on implemented climate change polices in Mardin. In the study qualitative analysis methods is used and the results are aimed to guide the policies to be applied. In the study, a semi-structured questionnaire is prepared and directed to participants. The data obtained from the research is interpreted by making descriptive and content analyzes. The snowball method is used to create the sample size. Most of the participants directly associated climate change with precipitation and stated that they felt the effect of drought as result of precipitation regime change in the region. In this respect, the effect of climate change in Mardin province is perceived with the degeneration of agricultural activities and drought. However, it is seen that the producers do not take effective precautions against climate change. Agriculture sector has been affected by these extreme wheather events and natural disasters; it has also negative contribution to carbon emission. Therefore, it is important to examine the interaction between climate change and the agricultural sector on a regional basis, to measure the perception levels of relevant stakeholders about the policies implemented, and to determine the individual measures they take against climate change. The study has a unique value in terms of showing the problems of the region with the attitudes of local stakeholders against climate change.
AN EMPIRICAL INVESTIGATION ON THE SOCIOECONOMIC DETERMINANTS OF DIVORCE RATES IN CEE COUNTRIES
(Dicle Üniversitesi, 2021) Çuhadar, Pınar; Açcı, Cafrı Reyhan; Department of Economics / İktisat Bölümü
The paper examines the relationship between divorce rates and socioeconomic variables in CEE countries whose economic and political regimes were changed from communism to capitalism. Factors such as regime change have been ignored, although there are many studies that examine the impact of changing gender roles and female labor force participation on the family structure. This study focuses on the impact of socio-economic impacts on divorce as well as regime change. Panel LM unit root test was used with the aim of finding out whether the destabilizing effect of divorce rates in CEE countries was permanent after the regime change. Also, panel data regression was employed to determine the social l factors that affected divorce rates from the years between 2008 nd 2017. The Czech Republic appears to have left behind the shock effect it experienced on divorce rates, which is considered to be a result of the country’s closeness to liberal values from past to present. The result of panel regression was supported the fact that growth rate and openness have a significant negative effect on divorce rates.
Evaluation of Foreign Tourists on Local Food Experiences
(Anatolia, An International Journal of Tourism and Hospitality Research, 2016) Ahmet Boz, Sadık Serçek, Gülseren Özaltaş Serçek
In the competitive Changing market, the priority ranking of consumer needs is also changing. Consumers no longer just buy physical products, they buy a total experience with products and services. Even if the goods and services they buy meet their rational expectations, Consumers are not loyal consumers, in the sense customer satisfaction does not correlate to customers’ loyalty relationship. There are new quests on new concepts, new formulas and suggestions in theory with changing customer needs. Experiences are economic proposals which are effecting customers as personal, can create strong feelings, affecting the values of customers, advice and loyalty trends positively. Surely the main way to offer customers a memorable experience, determination of certain factors and product features that affect the experience and advice of their customers and their loyalty is to better understand how that affects behaviour. However, it is still uncertain how to plan experience, how will it be applied and how to measure it in the strategic sense. Experiences forming factors, the number of studies investigating the effects on customer behaviour is extremely limited.
External Borrowing and Inflation in Turkey Between 2003 and 2015: A Simple Linear Regression Analysis
(International Journal of Economics and Financial Issues, 2016) Ekinci, Mehmet Behzat; Department of Economics / İktisat Bölümü
An economy using external resources can aim at several targets e.g. growth, public financing, covering a deficit in the balance of payments. However, external/foreign debt/borrowing (EXB) may result in some negative impacts such as a vicious cycle of increase in external debt, a decline in economic growth, huge budget deficits and an imbalance of payments in addition to inflation. This study examines the influence of external debts on inflation in Turkey from 2003 to 2015. In this context, the effect of external debt is measured by means of a simple linear regression analysis using both the consumer price index and the producer price ındex. The general opinion with regard to the effect of external debt on inflation is that they are positively related. Here this is confirmed for Turkey for the said period. The results show that both consumers and producers are negatively affected by external debt in terms of inflation.

GENDER EFFECT IN EXPLAINING MOBILITY PATTERNS IN THE LABOR MARKET: A CASE STUDY OF TURKEY
(WILEY, 2014) Tekgüç, Hasan; Tekgüç, Hasan; Department of Economics / İktisat Bölümü
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) Atay Polat, Melike; Öztürk, İlhan; Aslan, Alper; Özsolak, Baki; Atay Polat, Melike; Turan, Zubeyir; Department of Economics / İktisat Bölümü
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) Atay Polat, Melike; Savranlar, Buket; Atay Polat, Melike; Yiğit, Yüksel; Aslan, Alper; Department of Economics / İktisat Bölümü
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.

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; Department of Economics / İktisat Bölümü
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) Atay Polat, Melike; Aslan, Alper; Atay Polat, Melike; Topalgokcelli, Emre; Esmeray, Murat; Department of Economics / İktisat Bölümü
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
