Energy-Saving Behavior of Turkish Women: a Consumer Survey on the Use of Home Appliances
(Sage Publications Ltd, 2017) Ucal, Meltem Şengün
This paper focuses on energy-related attitudes and behaviors of Turkish women who are the main users of electrical home appliances responsible for most household energy consumption. Answers from 1323 female respondents surveyed through a unique questionnaire formed the dataset. The results from analysis of variance show that education has a significant effect on the relationship between energy saving and awareness and attitudes about climate change. Significant differences also exist between education level groups in terms of knowledge of the classification of energy-saving electrical home appliances. Responses to questions related to energy-saving purchasing behaviors are consistently higher for knowledgeable respondents. The paper then uses factor analysis and ordinal logit models to reveal interactions between energy-saving behavior regarding electrical home appliances and several factors namely awareness sensitivity essentials and receptiveness. The identification of these factors can provide useful insights for policy makers that enable them to construct energy-saving policies specifically tailored toward women.

Measuring Energy Intensity in Japan: a New Method
(Elsevier, 2017) Zaim, Osman; Gazel, Tuğçe Uygurtürk; Akkemik, K. Ali
Energy intensity and energy conservation have been important pillars of energy policies in Japan. Recently the government has introduced new initiatives to enhance energy efficiency and reduce energy intensity. We analyze the energy intensity in Japan for the period 1973-2006 by proposing a new method which takes into account all other inputs used in production and corrects for the bias in the traditional energy intensity measure. We show that the traditional energy intensity measure has serious flaw. The traditional measure overestimates actual energy intensity before the mid-1980s and largely underestimates afterwards. It is found that aggregate energy intensity has risen remarkably from 1991 to 2001. The main cause of this rise is the rapid rise in energy intensity in manufacturing and energy sectors.

TÜRK İMALAT SANAYİ SERMAYE STOKU TAHMİNİ ÜZERİNE BİR ÇALIŞMA: 2003-2015
(Balıkesir Üniversitesi Sosyal Bilimler Enstitüsü, 2017) Tunçsiper, Bedriye; Gazel, Tuğçe Uygurtürk
En temel üretim girdilerinden biri olarak sermaye, üretimin analizi ve değerlendirilmesi çalışmalarında kritik bir role sahiptir. Diğer girdilerden farklı olarak üretime azalan oranlarda da olsa katkısı bir dönemden fazla olan sermaye girdisinin; bu doğrultuda doğru hesaplanması iktisadi faaliyet kollarının özellikle verimlilik analizi çalışmaları için önemli bir gerekliliktir. Bu araştırmanın amacı Türk imalat sanayi alt sektörlerinde (NACE 2’li kodda) güncel veri seti kullanarak sermaye birikim verisinin oluşturulmasıdır. Çalışmada sermaye stoku (birikimi) hesaplamada genel olarak başvurulan yöntem olan Aralıksız Envanter Yöntemi (AEY)’e başvurulmuştur. 2003-2015 yılları arasında sermaye stok girdisi oluşturulan imalat sanayi alt sektörlerinin her biri için yıllara göre toplam sermaye stoku içindeki değişim oranları ve sıralamaları sunulmuştur

The Role of Intangible Assets in Explaining the Investment-Profit Puzzle
(Oxford Univ Press, 2019) Orhangazi, Özgür
Starting around the early 2000s, and especially after the 2008 crisis, the rate of capital accumulation for US nonfinancial corporations has slowed down despite relatively high profitability; indicating a weakening of the link between profitability and investment. While the literature mostly focuses on financialisation and globalisation as the reasons behind this slowdown, I suggest adding another layer to these explanations and argue that, in conjunction with financialisation and globalisation, we need to pay attention to the increased use of intangible assets by nonfinancial corporations in the last two decades. Intangibles such as brand names, trademarks, patents and copyrights play a role in the widening of the profit-investment gap as the use of these assets enables firms to increase market power and profitability without necessarily generating a corresponding increase in fixed capital investment. After discussing the ways nonfinancial corporations use intangible assets, I look at large corporations in the USA and find the following: (i) The ratio of intangible assets to the capital stock increased in general. This increase is highest for firms in high-technology, healthcare, nondurables and telecommunications. (ii) Industries with higher intangible asset ratios have lower investment to profit ratios. (iii) Industries with higher intangible asset ratios have higher markups and profitability. (iv) The composition of the nonfinancial corporate sector has changed and the weight of high-technology and healthcare firms has increased; but this increase did not correspond to an equal increase in their investment share. The decline in the investment share of durables, nondurables and machinery is matched by an increase in the investment share of location-specific industries with low intangible asset use, most notably firms in energy extraction. In general, these firms have steadier markups and higher investment to profit ratios. (v)Yet, intangible-intensive industries' profitability has increased faster than their share of investment or total assets. All in all, these findings are in line with the suggestion that the increased use of intangible assets enables firms to have high profitability without a corresponding increase in investment.

Recent Industrial Policies in Japan
(Springer International Publishing, 2015) Akkemik, K. Ali
Traditional Japanese industrial policies have since the 1990s evolved towards knowledge-based industrial policies. In this chapter we first explain the salient features of both the traditional and knowledge-based industrial policies and compare them from the perspective of the role of the government. Knowledge-based industrial policies emphasize the role of the government as a facilitator and coordinator rather than a guide. Accordingly the policy instruments differ as well. The changing global economic environment in the era of the knowledge economy and the emergence of new regional rivals Korea and China also led to significant changes in policy design and corporate governance styles as well. On the other hand we argue that there is still an influence of the developmental state practices in policy-making. To present a full account of the recent industrial policies in Japan we present the recent changes in the policy-making process as well as the economic mindset with reference to the official documents on industrial policies. © Springer International Publishing Switzerland 2015.

(Cahit AYDEMİR, 2010) Kızıl, Ahmet; Güler, Fazıl; Ceylan, Cengiz; Kızıl, Cevdet; Keskin, Ayşe İrem; Buget, Püren
The primary objective of this paper is to determine whether the present managers of Turkish tourism sector perform their jobs in accordance with their qualifications. For this purpose, questionnaires were distributed to managers and responses were evaluated. The secondary purpose of this study is to identify if employees in tourism industry has the required qualifications. Also, if the sector has low efficiency, reasons are investigated. This study uses the survey method. Questionnaires were distributed to 222 managers in the tourism sector, who mainly work in Istanbul and Izmir. 183 managers in accommodation enterprises, 22 managers in travel agencies and 17 managers in food and beverage companies were interviewed face-to-face and questionnaire forms were filled. The survey includes 52 questions that collect information about managers and their organizations. The questionnaires should also test if the managers are in a fitting position and they use their authority properly.

A Mechanism Design Approach To Allocating Central Government Funds Among Regional Development Agencies
(Springer, 2014) Kıbrıs, Özgür; Tapkı, İpek Gürsel
To allocate central government funds among regional development agencies we look for mechanisms that satisfy three important criteria: efficiency (individual and coalitional) strategy proofness (a.k.a. dominant strategy incentive compatibility) and fairness. We show that only a uniform mechanism satisfies all three. We also show that all efficient and strategy proof mechanisms must function by assigning budget sets to the agencies and letting them freely choose their optimal bundle. In choosing these budget sets the agencies' private information has to be taken into account in a particular way. The only way to additionally satisfy a weak fairness requirement (regions with identical preferences should be treated equally) is to assign all agencies the same budget set as does the uniform mechanism. Finally and maybe more importantly we show that the central government should not impose constraints on how much to fund an activity (e.g. by reserving some funds only for a particular activity): otherwise there are no efficient strategy proof and fair mechanisms no matter how small these constraints are.
İKLİM DEĞİŞİKLİĞİ SÜRECİNDE EKONOMİDEKİ YENİ KAVRAMLAR VE YAKLAŞIMLAR
(Dokuz Eylül Üniversitesi Sosyal Bilimler Enstitüsü, 2017) Ucal, Meltem Şengün; An, Nazan; Kurnaz, Levent
İklim değişikliği günümüzde tüm dünya üzerinde etkili olmakla birlikte özellikle gelişmekte olan ülkelerde bölgesel bazda daha önemli etkilere sahip, gelecekte de ekosistem hizmetleri aracılığıyla insanlığı ciddi şekilde tehdit etme potansiyeli bulunan küresel bir sorundur. İklim değişikliğine büyük ölçüde insan aktivitelerinin yol açtığı düşünüldüğünde, iklim değişikliğinde ekonomik aktivitelerin rolünün tartışılmaz olduğu açıktır. Küresel nüfus artışına bağlı olarak ekonomik aktivitelerde de artış yaşanacağı ifade edilmektedir. Özellikle büyüme odaklı ekonomilerde ekonomik büyümenin sağlanması yönünde gerçekleştirilen ve nüfus artışıyla birlikte daha da artacağı düşünülen ekonomik aktivitelere bağlı fosil yakıt tüketimi ve arazi kullanımı değişikliği sonucu atmosferdeki sera gazı konsantrasyonu artmaktadır ve gelecek birkaç on yılda çok daha artması beklenmektedir. Ekonomik büyümenin istikrarlı bir şekilde devam ettirilebilmesi paralelinde doğal kaynakların sürdürülebilirliğinin sağlanması da büyük önem taşımaktadır. Ekonomik büyümenin hız kesmeden devam edeceğini varsaydığımızda çevresel sınırlamaların varlığını da dikkate almamız ve kaynakları sürdürülebilir hale getirmemiz gerekmektedir. Sürdürülebilir bir kaynak kullanımı da ancak kaynak kullanımının ekonomik büyümeden ayrıklaştırılması yoluyla mümkün görünmektedir ve bu kavram küresel kaynak akışı paralelinde dikkat edilmesi gereken bir kavram olarak ortaya çıkmaktadır. Çalışmamız bu temel üzerine kurulmuştur. Makale, ayrıklaştırmanın önemini vurgulamakta ve ayrıklaştırmayı her yönüyle ele almaktadır. Ayrıklaştırmanın nasıl ölçüldüğü ve ayrıklaştırma sürecinin nasıl izlenmesi gerektiği incelenerek, ayrıklaştırma açısından gelişmiş ülke ve gelişmekte olan ülke farklılıkları ve iklim değişikliği kapsamında ayrıklaştırma süreci değerlendirilmiştir.
Kalkınma, Kapitalizmin Mantığı ve Eşit Olmayan Gelişme
(İ.Ü. İktisat Fakültesi Mezunları Cemiyeti, 2011) Orhangazi, Özgür
Kapitalizm, ortaya çıkışından bu yana dünya üzerinde eşit olmayan bir gelişme üretmiştir. İlk başlarda, kapitalizmin ortaya çıktığı bölgeler ve bunların uzantılarıyla dünyanın geri kalanı arasında kurulan ilişkilerin yarattığı eşit olmayan gelişme dinamikleri, sistemin mantığı tarafından sürekli yeniden üretilmektedir. Dünyanın belirli yerlerinde ortaya çıkan iktisadi gelişme, çoğu zaman başka bölgelerde ‘azgelişme’ yaratmaktadır. Gerek 1980 öncesinin devletçi kalkınma politikaları gerekse daha sonra devreye sokulan neoliberal politikalar, ‘azgelişmiş’ ülkelerin ‘gelişmiş’ ülkeler seviyesine ulaşmasını sağlayamamıştır. Gerçek anlamda bir kalkınmadan söz edebilmek için bu piyasacı/devletçi kalkınma ikileminden koparak yeni bir paradigmanın arayışı içerisine girilmesi ve hem iktisadi hem de insani kalkınmanın sermayenin ihtiyaç ve kararlarının insafına bırakılmaması gerekmektedir.

Income Inequality and Fdi: Evidence With Turkish Data
(Routledge Journals Taylor & Francis Ltd, 2016) Ucal, Meltem Şengün; Haug, Alfred Albert; Bilgin, Mehmet Hüseyin
This article explores how foreign direct investment (FDI) and other determinants impact income inequality in Turkey in the short- and long-run. We apply the nonlinear auto-regressive distributed lag (ARDL) modelling approach which is suitable for small samples. The data for the study cover the years from 1970 to 2008. The empirical results indicate the existence of a co-integration relationship among the variables with asymmetric adjustment of the income distribution in the short- and long-run. The negative impact of FDI on the Gini coefficient decreasing income inequality is statistically significant in the short- and long-run though with a quantitatively small impact in both cases. In the short run GDP growth increases inequality initially an effect that is reversed in the next period increases in domestic gross capital formation decreases inequality and increases in the literacy rate have very minor adverse effects on income equality. However in the long run these variables have no statistically significant effects on the Gini coefficient. A reduction in the population growth rate reduces inequality in the short run but has no effect in the long run whereas an increase in the rate reduces inequality in the long run but has no effect in the short run.
Inflation Targeting Framework: Leading Indicator Variables of Inflation in Turkey
(Çukurova Üniv. Sosyal Bil. Enst., 2005) Alıcı, Aslı; Ucal, Meltem Şengün
Türkiye’de esnek döviz kuru uygulamasına geçilmesinin ardından, para politikasının ne şekilde uygulanacağı sorusu önemini korumaktadır. Yeni bir para politikası uygulaması olarak enflasyon hedeflemesine geçilmesi diğer bir ifade ile nominal çapa olarak belirlenen enflasyon hedefinin kullanılması, uygulamada güvenirlik derecesi yüksek enflasyon tahmin modellerinin oluşturulmasını gerektirmektedir. Bu çalışma, Türkiye’deki enflasyon olgusuna ilişkin gösterge değişkenlerin saptanmasına yöneliktir. Enflasyon hedeflemesine geçilebilmesi için gerekli ön koşulların ortaya konulmasının ardından, enflasyon üzerinde belirleyici (gösterge niteliğinde) olan değişkenler, VAR analiziyle belirlenmiştir. VAR modeline karşı yapılan eleştirilere rağmen enflasyon modellemesi için VAR analizinin seçilmesinde, bu analiz tekniğinin yapısal model üzerinde herhangi bir kısıtlama gerektirmeksizin dinamik ilişkileri verebilmesi ve hangi değişkenin içsel hangi değişkenin dışsal olduğuna karar verme zorluğunun yaşanmamasıdır. Enflasyon hedefinin geleceğe yönelik olmasından dolayı tahmin modellerinde ileriye dönük belirleyici nitelikteki değişkenlere büyük ağırlık verilmektedir. Bu çerçevede, çalışma diğer politika araçları ve geliştirilecek yeni enflasyon serileri ile genişletilebilecek belirleyici göstergeler bazında bir ön model çalışması olarak değerlendirilmelidir.

Sabotage in Team Contests
(Springer, 2019) Dogan, Serhat; Keskin, Kerim; Saglam, Cagri
In the contest literature sabotage is defined as a deliberate and costly activity that damages the opponent's likelihood of winning the contest. Most of the existing results suggest that anticipating a possible sabotage contestants would be discouraged from exerting high efforts. In this paper we investigate the act of sabotage in a team contest wherein team members exert costly efforts as a contribution to their team's aggregate effort which in turn determines the contest's outcome. For the baseline model with no sabotage there exists a corner equilibrium implying a free-rider problem in each team. As for the model with sabotage our characterization of Nash equilibrium reveals two important results: (i) a unique interior equilibrium exists so that the free-rider problem no longer is a concern and (ii) the discouragement effect of sabotage vanishes for some players. On top of those conclusions we investigate the team owner's problems of prize allocation and team formation with the objective being to maximize his team's winning probability.

Detecting Structural Changes Using Wavelets
(Academic Press Inc Elsevier Science, 2015) Yazgan, M. Ege; Ozkan, Harun
We propose a powerful wavelet method to identify structural breaks in the mean of a process. If there is a structural change in the mean the sum of the squared scaling coefficients absorbs more variation leading to unequal weights for the variances of the wavelet and scaling coefficients. We use this feature of wavelets to design a statistical test for changes in the mean of an independently distributed process. We establish the limiting null distribution of our test and demonstrate that our test has good empirical size and substantive power relative to the existing alternatives especially for multiple breaks.

Ethnic Fractionalization Conflict and Educational Development in Turkey
(Pergamon-Elsevier Science Ltd, 2019) Oyvat, Cem; Tekgüç, Hasan
We examine the impact of ethnic fractionalization and conflict on limiting the educational development in Southeastern Turkey. Our estimates show that although the armed conflict in the region did not directly hinder education investments it reduced school enrolment rates at middle and high school levels while increasing enrolment at the primary school level. Moreover we show that provinces with higher percentages of Kurdish population received less education investment. These results suggest that the neglect of Kurdish areas is an important factor behind Southeastern Turkey's educational underdevelopment while land inequality and the armed conflict had mixed effects on education in the region.

The Personality and Leadership Style of Recep Tayyip Erdogan: Implications for Turkish Foreign Policy
(Routledge Journals Taylor & Francis Ltd, 2011) Görener, Aylin; Ucal, Meltem Şengün
Recep Tayyip Erdog. an is clearly the most controversial figure in recent Turkish political history. His preponderance in political life is remarkable even by Turkish standards. Because Erdog. an is so powerful and has effectively weakened most internal checks on his power any attempt to explain Turkey's recent foreign policy outcomes will be seriously lacking without considering his leadership impact. The purpose of this study is to investigate Erdog. an's worldview and leadership style and evaluate their impact on his government's policy processes and outputs. To do that we employ the Leadership Trait Analysis technique to construct the leadership profile of Erdog. an through content analysis of his verbal records while in office. We contend here that our understanding of AKP-era Turkey is enhanced if we offer a systematic and rigorous account of Erdogan's personality and that he presents a clear example of the importance of taking individual-level variables seriously in foreign policy analysis.
Electronic Money in 2000's
(Fırat Üniversitesi Sosyal Bilimler Dergisi, 2004) Ucal, Meltem Şengün
Para, dünya ekonomilerinin tümü için gerekli bir araçtır. Buna karşın elektronik para da gelişmiş ülkeler için gerekli bir araç haline gelmiştir. Günümüzde internet ortamı yolu ile yapılan finansal hizmetlerdeki muameleler için elektronik para ve elektronik ödeme sistemleri oldukça popülerdir. Elektronik sistemlerde meydana gelen bu değişmeler ekonomik ortamda gerçekleşen perakende satış ödemelerinde geleneksel işlemlerin yanında iki yeni formu ortaya çıkarmıştır. Bunlar, bir kişisel bilgisayar ile evden veya işyerinden banka işlemleri yapmak ve elektronik nakit kullanımıdır. Söz konusu muameleler güvene dayalı gerçekleştirilir. Özellikle de teknolojilerin hızla değiştiği 2000’li yılları kat edeken, bu sistemde gerçekleşmesi gereken en önemli unsur elektronik paranın kanunlar çerçevesinde değerlendirilmesidir. Fakat Türkiye elektronik para sistemleri için henüz bir kanuni çerçeve çizmemiştir.

Energy Consumption-Gdp Nexus: Heterogeneous Panel Causality Analysis
(Elsevier Science Bv, 2012) Akkemik, K. Ali; Göksal, Koray
Existing studies examining the Granger causality relationship between energy consumption and GDP use a panel of countries but implicitly assume that the panels are homogeneous. This paper extends the Granger causality relationship between energy consumption and GDP by taking into account panel heterogeneity. For this purpose we use a large panel of 79 countries for the period 1980-2007. Specifically we examine four different causal relationships: homogeneous non-causality homogeneous causality heterogeneous non-causality and heterogeneous causality. The results show that roughly seven-tenths of the countries exhibit bi-directional Granger causality two-tenths exhibit no Granger causality and one-tenths exhibit unidirectional Granger causality.

Panel Data Analysis of Foreign Direct Investment and Poverty From the Perspective of Developing Countries
(Elsevier Science, 2014) Ucal, Meltem Şengün
The purpose of this paper is to assess the relationship between foreign direct investment (FDI) and poverty at the macro-pathway in selected developing countries. The contribution to host countries from FDI can take several forms such as the transfer of technology human capital development increased competition in domestic markets and the generation of corporate tax revenues among others. The paper develops a data set and an econometric model to analyse FDI flows and poverty relations at the macro level panel data set. Results show that there is statistically significant relationship between FDI and poverty and it is obvious that FDI reduces poverty in selected developing countries. (C) 2014 The Authors.
