A Fuzzy AHP approach for selecting a global supplier in pharmaceutical industry
(2012) Taş, Ayşegül; 29252
Our study looks into the strategy that should be pursued for raw material procurement by a pharmaceutical firm operating in Turkey. In this paper, pharmaceutical research companies and food industry chemists operating in the global market in the pharmaceutical industry are examined and a suitable supply strategy is suggested for a company operating in Turkey under the specified criteria. The supplier selection is a multi-criterion problem which includes both qualitative and quantitative criteria. This paper proposes a fuzzy analytic hierarchy process (fuzzy-AHP) to efficiently tackle both quantitative and qualitative criteria involved in selection of global supplier in pharmaceutical industry. Four main criteria and thirteen sub-criteria were identified for supplier selection in this problem. The number of suppliers to be selected under these criteria was identified as four. A numerical example presented illustrates the different selection criteria to select the best supplier in pharmaceutical industry.

An empirical survey of consumer ethnocentrism in Kazakhstan and the preference of consumers on imported products
(Ahmet Yesevi Univ, 2017) Nakip, Mahir; Nakip, Mahir; Gokmen, Aytac; Gökmen, Aytaç; 118963; Uluslararası Ticaret ve Finansman
The reality of globalization declines the frontiers for cross border international trade and investments as well as functions as a means to converge the consumer needs and expectations on a global base. The convergence of the expectations of consumers is considerably beneficial for international businesses in their international marketing activities. However, this issue does not realize in every country or regional market. Yet, consumer ethnocentrism is a profound obstacle for international businesses which emphasis nationalistic sentiments, pride and the rejection of any product or idea that is made in another country without any rationale reasoning. Thus, this study is aimed at researching the subject of consumer ethnocentrism in the Central Asian Turkish Republic of Kazakhstan. The results indicate that there is not a strong relation between ethnocentric perceptions and product necessity in Kazakhstan. Also, sub-dimensions of ethnocentrism have different correlation levels with each imported products. In addition, religious and moral values are not effective factors in explaining the variation in imported products.

At the convergence of energy corridors: energy situation in Turkey and a critical evaluation with Porter's model
(Igi Global, 2017) Gökmen, Aytaç; Gokmen, Aytac; Nakip, Mahir; Nakip, Mahir; 17660; 118963; Uluslararası Ticaret ve Finansman
Turkey is at the threshold of Eurasia connecting various energy corridors. It has an improving economic volume and is one of the 20 largest economies in the world. Energy and economic development are highly correlated. Turkey is dependent on imported energy. In order to keep up with the economic expansion, the energy requirements of Turkey must be met in a diversified, timely and reliable way. Thus, the aim of this paper is to define the geographic disposition of Turkey at the convergence of energy lines, review its energy situation comprehensively and make critical evaluations on energy and economy related issues, also with using the diamond model developed by Michael E. Porter resting on credible national and international publications and data.

Business groups and internal capital markets
(Routledge Journals, Taylor & Francis Ltd, 2007) Gonenc, Halit; Kan, Ozgur B.; Karadagli, Ece C.
We compare the performance of firms affiliated with diversified business groups with the performance of unaffiliated firms in Turkey, all emerging market. We address the question of whether group-affiliated firms create internal capital markets or control large cash flows. Our findings indicate that group affiliation improves a firm accounting performance, but not stock market performance. Deviation of cash-flow rights front voting rights has a negative but insignificant effect on accounting performance, but a significant effect on market performance. We also find that a firm's accounting, but not stock market, performance increases with the level of group diversification. Our results show that internal capital markets play an important role for the existence of business groups in all emerging market context.

Cointegration, causality and the transmission of shocks across wheat market in Pakistan
(Springer, 2009) Klasra, Mushtaq Ahmad; Klasra, Mushtaq Ahmad; Uluslararası Ticaret ve Finansman
This paper uses quarterly price data and examines the transmission of shocks across different spatially separated locations besides identifying causality among these locations. Johansen and Juselius's (Econ. Stat., 52, 160-210, 1990) multivariate cointegration procedure identified two cointegrating vectors among these locations. Following Toda and Yamamoto (J. Econom., 66, 225-250, 1995), causality tests showed only one bi-directional causality and it was between Peshawar and Hyderabad locations. Faisalabad and Sargodha appeared independent (i.e. exogenous) market locations in price discovery process. Peshawar market showed maximum (i.e. 5) number of significant links. The generalized impulse response functions, though, suggested similar (cyclical) pattern of responses across the markets, but their time profile, which provides insight into the system's speed of convergence to long run equilibrium path, varied with different level of extent and persistency. Responses to shock originating in consumption markets (i.e. Karachi, Peshawar and Lahore) remained short lived; whereas the shocks stemming from surplus wheat producing locations (i.e Multan, Sargodha and Faisalabad) produced long and more persistent responses.

Competitiveness of Major Exporting Countries and Turkey in the World Fishery Market: A Constant Market Share Analysis
(2005) Klasra, M.A.; Klasra, Mushtaq Ahmad; Fidan, H.; Uluslararası Ticaret ve Finansman
The purpose of this study is to examine whether and to what extent the shares of selected countries' fishery exports in the world markets reflect their international competitiveness. The Constant Market Share (CMS) model, which decomposes export growth into some broad components (i.e., structural effects, market effects, commodity effects and competitive effects), is applied to examine this issue. The results of decomposition analysis revealed that structural factors have been more significant in explaining the growth of exports. The growth effects, though, appeared positive for each country, the exports of open economies like Canada, the United States, Iceland and Turkey benefited more from the growth of world exports. The analysis of commodity composition and market effects suggests that countries like Canada, the United States, Iceland and Turkey were pursuing the product differentiation policy and were penetrating in those markets, which have been growing relatively faster. These countries remained committed throughout the sample period (i.e., 1980-2000) to export their diversified products in fast-growing markets. The analysis of competitiveness effects, which are derived as a residual, show that Norway, Spain, the United States, Indonesia, Thailand, sChile and China were strong fishery exporters and increased their competitiveness during the sample period.

Copyright Protection By Robust Digital Image Watermarking in Unsecured Communication Channels
(Institute of Advanced Engineering and Science, 2017) Alasafi, L.; Göksu, T.; Albayati, A.
The transition from analog technologies to digital technologies has increased the ever-growing concern for protection and authentication of digital content and data. Owners of digital content of any type are seeking and exploring new technologies for the protection of copyrighted multimedia content. Multimedia protection has become an issue in recent years, and to deal with this issue, researchers are continuously searching for and exploring new effective and efficient technologies. This thesis study has been prepared in order to increase the invisibility and durability of invisible watermarking by using the multilayer Discrete Wavelet Transform (DWT) in the frequency plane and embedding two marks into an image for the purpose of authentication and copyright when digital content travels through an unsecured channel. A novel watermarking algorithm has been proposed based on five active positions and on using two marks. In addition to the extraction process, watermarking images will be subjected to a set of attack tests. The evaluation criteria have been the bases of assessing the value of SNR, PNSR, MAE and RMSE for both the watermarking images and the watermarking images after attacks, followed by the invisibility of the watermarking being measured before and after the attacks. Our lab results show high robustness and high quality images obtaining value for both SNR and PNSR. © 2017 Institute of Advanced Engineering and Science. All rights reserved.

Developments And Prospects In e–Government Implementations In Turkey
(2010) Gökmen, Aytaç; 17660; Uluslararası Ticaret ve Finansman
21st century is the age of globalization. Globalization is the process of transforming regional or local developments and phenomena into global realities. Globalization is also a process that unifies the world into a single society which is a combination of economical, social, political and technological influences. The most substantial actor in this process is the Internet and its contributions to data and knowledge procurement among the states, legal and natural persons. Moreover, Turkey is one of the leading states in the world to encourage the use of Internet and e – government implementations to integrate Turkey with that of the world and render premium services to her citizens and other related entities. The e – government which is also known as e- gov, online government or digital government, is a concept to utilize the Internet technology as a means to exchange information, provide services and transactions with citizens, business and other branches of government. Some e – government implementations both in practice and forthcoming in Turkey are e – Government Gateway, Public Sector Network, Informantions Disaster Recover System and Justice Net. It is aimed to constitute and develop knowledge society; to facilitate access to knowledge, decrease time consumption, provide better access to public services and enhance efficiency, ensure transparency and accountability, lower the costs and save sources in Turkey by e- government regulations. The aim of this study is to reveal the developments and realities of e – government in Turkey theoretically depending on comprehensive international and national publications

Does the incomplete information matter with export quotas?
(2006) Yazici, M.; Yazıcı, Mehmet; 144084; İktisat
This study investigates whether or not incomplete information matters when the government adopts the export quotas in intervening in the oligopolistic export markets. Incomplete information the government has is about the unit-production cost of the domestic firm. It is shown first that quotas optimal under full information (full-information policy) result in Stackelberg outcome, the best outcome in a non-cooperative setting from the domestic firm's point of view. When the full-information policy is implemented in the presence of incomplete information, it is found that no cost-type has an incentive to misrepresent itself as the other type. This means that full-information outcome will be achieved with incomplete information. Hence, incomplete information does not matter in the case of export quotas. This result, however, does not carry over to the case of more than one domestic firm. © 2006 Asian Network for Scientific Information.

Dynamic linkages between renewable energy, carbon emissions and economic growth through nonlinear ARDL approach: Evidence from Iran
(Public Library Science, 2021) Karimi, M. S.; Ahmad, S.; Karamelikli, H.; Dinc, D. T.; Khan, Y. A.; Sabzehei, M. T.; Abbas, S. Z.; 52039
This study examines the relationship between economic growth, renewable energy consumption, and carbon emissions in Iran between 1975-2017, and the bounds testing approach to cointegration and the asymmetric method was used in this study. The results reveal that in the long run increase in renewable energy consumption and CO2 emissions causes an increase in real GDP per capita. Meanwhile, the decrease in renewable energy has the same effect, but GDP per capita reacts more strongly to the rise in renewable energy than the decline. Besides, in the long run, a reduction of CO2 emissions has an insignificant impact on GDP per capita. Furthermore, the results from asymmetric tests suggest that reducing CO2 emissions and renewable energy consumption do not have an essential role in decreasing growth in the short run. In contrast, an increase in renewable energy consumption and CO2 emissions do contribute to boosting the growth. These results may be attributable to the less renewable energy in the energy portfolio of Iran. Additionally, the coefficients on capital and labor are statistically significant, and we discuss the economic implications of the results and propose specific policy recommendations.

Dynamics of wheat prices in the wake of market reforms: the case of Pakistan
(Springer, 2006) Klasra, MA; Klasra, Mushtaq Ahmad; Kiral, T; Uluslararası Ticaret ve Finansman
Using Autoregressive Conditional Heteroskedastic (ARCH) method, this paper examines the effects of market reforms on the distribution of real mean prices and their variability before and after reforms. It is found that market-oriented reforms benefited producers and consumers alike. Empirical evidences, generally, support theoretical assertion that mean prices decline in most urban areas and increase in those markets that are located in surplus producing areas. The results also showed that market reforms lead to more price volatility.
Ethıcal Issues In Marketıng: An Applıcatıon For Understandıng Ethıcal Decısıon Makıng
(2014) Özsaçmacı, Bülent; Külter Demirgüneş, Banu; Özsaçmacı, Bülent; 19729; Uluslararası Ticaret ve Finansman
In recent years business ethics and social responsibility have gained great importance in marketing practices, especially in societal marketing practices. Businesses infinitely struggle to indicate their contributions to society. Consumers consciously evaluate this contribution. Manipulated consumer choices and unethical marketing applications can affect purchasing behavior. Particularly intense competition, globalization and societal consciousness transform businesses into social organizations and lead them into marketing efforts offering social value. Although business ethics and social responsibility of businesses have gained more attention in recent years, defining consumers’ perceptions on ethical issues is still minimal. This study presents an empirical research of consumer perceptions on ethical issues. Reflection of this perception on purchasing behavior is also another important issue to be considered. The aim of this study is to investigate the factors related with ethical issues in marketing practices and to reveal possible influences of these factors on consumers’ ethical decision making. The main objective of the study is to find out consumers’ perceptions on businesses’ ethical issues such as misleading advertising, deceptive packaging and to reveal the impact of these issues on their ethical purchasing behavior or ethical decision making. It also reveals which criteria is more important for ethical decision making. This study reveals that consumers reflect their ethical perceptions on their purchasing behavior. Each ethical issue has been found to be a positive effect on purchasing behavior. Businesses’ practices on packaging has been indicated as the most effective ethical issue on purchasing behavior. The study is considered to be a significant outcome for businesses to direct their advertising, packaging and other activities.

Export-led economic growth and the case of Brazil: An empirical research
(Routledge, 2019) Temiz Dinç, D.; Gökmen, Aytaç; Gökmen, A.; 52039; 17660; Uluslararası Ticaret ve Finansman
The world has been globalized much more than ever before and this process integrates the economies of countries. Moreover, one means of integrating the economies of countries is trade. In this instance, the export-led economic growth emerges as a considerable determinant. Export-led economic growth is beneficial for the countries since it facilitates the inflow of foreign exchange, increases production, creates new employment opportunities and enhances the overall commercial volume. In this study, the correlation between export-led economic growth is explored for Brazil. Therefore, according to the findings of this paper as well as econometric and statistical applications, there is a bi-directional causality in Brazil since 1960s between economic development and exports in the long-run (this could also be termed as feedback); furthermore, in the short-run, there is export-led economic growth. The novelty of this paper is that, it is one of the latest studies investigating export-led economic growth for Brazil. © 2019, © 2019 Taylor & Francis Group, LLC.

Mal ve sermaye akışı özellikle II. Dünya Savaşı'nın sona ermesi ile hızlanmış, doğrudan yabancı sermaye (DYS) yatırımlarının birikimini ve bununla birlikte dünyanın pek çok yerinde de çokuluslu işletmelerin (ÇUİŞ) uğraşılarının artmasını kolaylaştırmıştır. Ancak, DYS yatırımlarının önemli bir devinim kazanması 1980'ler sonrasında olmuştur. DYS yatırımlarının özellikle gelişmiş ülkelerden gelişen ülkelere akması bilgi, teknik beceri, teknoloji, finansal sermaye ve insan kaynağı aktarımını kolaylaştırmış ve de ülkelerin iktisaden gelişmesine ve kalkınmasına katkıda bulunmuştur. Türkiye açısındansa, DYS yatırımları 1980 öncesi çok önem kazanamamış, 1990'lar sonrası artmaya başlamış ve ancak 2000'ler sonrası özelleştirme uygulamaları ile tepe yapmıştır. Türkiye'de DYS politikaları ve özelleştirme, 2002 yılı sonbaharında Adalet ve Kalkınma Partisi (AKP) Hükümeti'nin iktidara gelmesi ile büyük önem kazanmıştır. Türkiye'de birçok çevre AKP'nin DYS ve özelleştirme politikalarının başarılı olduğunu iddia etmektedir. Ancak, çeşitli makroekonomik değerler göz önüne alındığında AKP'nin özelleştirme politikalarının Türkiye Cumhuriyeti'nin ekonomik gücü ve bağımsızlığı açısından bir başarısızlık olduğu söylenebilir. Dolayısı ile, bu çalışmanın amacı DYS kuramı üzerinde durarak, Türkiye'nin DYS ve özelleştirme politikalarını eleştirel açıdan tenkit etmek ve bu konudaki AKP politikalarının başarısızlığını ortaya koymaktır

FDI inflow as an international business operation by MNCs and economic growth: an empirical study on Turkey
(Elsevier Science Bv, 2014) Temiz, Dilek; Temiz, Dilek; Gokmen, Aytac; Gökmen, Aytaç; 52039; 17660; Uluslararası Ticaret ve Finansman
The issue of foreign direct investment (FDI) has been affecting the world economy for years and is a considerable subject for both developed and developing countries. FDI is the fixed form of international business operation made across the national borders made mostly by the multi national corporations (MNCs). The positive impact of FDI inflow in a host country is expected to emerge as capital accumulation, technology transfer, know-how acquisition, innovative capacity and economic growth eventually. In this study, it is aimed to address the FDI literature depending on comprehensive international publications and then to analyze the FDI inflow and GDP growth in Turkey with econometric methods. The relation between FDI inflow and GDP growth is analyzed by using the Johansen cointegration test and Granger causality analysis. Afterwards, a regression equation is estimated by using the ordinary least squares method (OLS). Prior to applying the Cointegration test, the stationarity and integration degrees of the series are determined by the augmented Dickey-Fuller test (ADF). Consequently, resting on the results of entire analysis, it is possible to mention that no significant relation is determined between the FDI inflow and GDP growth in Turkey both in the short and long run.
