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.
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

Declining Poverty and Inequality in Turkey: the Effect of Social Assistance and Home Ownership
(Routledge Journals Taylor & Francis Ltd, 2018) Tekgüç, Hasan
Social assistance has become prominent in combating poverty in developing countries and has also contributed to the popularity and election success of governments implementing it. In this paper I employ household surveys and investigate the effect of social assistance on poverty and income inequality in Turkey. I also review the recent literature on poverty as well as different components of social protection spending: education health pensions and housing. In the empirical analysis I show that pensions still constitute the bulk of public transfers to households. Moreover home ownership ameliorates poverty and inequality for Turkey. Despite its modest amounts social assistance reduces poverty and its marginal effect on income inequality is larger than other income sources. These findings suggest that increases in social assistance budgets should accompany other policy measures in combating poverty and inequality.

Perceived Happiness, Perceived Trust and Perceived Income Levels: the Case of the Reunified Germany
(Savez Ekonomista Vojvodine, 2019) Ucal, Meltem Şengün; Günay, Simge
This study explored the possible impact of perceived income on individual (perceived) happiness in Eastern and Western Germany in relation to perceived trust and four socio-economic variables, namely gender, age, marital status and employment status. To examine the relationship between these variables, a generalized ordered logit model was applied using the World Values Survey data. Bootstrapping and marginal effects were used to obtain a more robust model. The findings provided insights regarding the impact of perceived income and perceived trust on individual (perceived) happiness in both regions after reunification. Perceived income had a positive effect on all happiness categories in both regions. Perceived trust had a stronger positive impact on individual happiness than that of perceived income, although its significance varied across individual (perceived) happiness categories. Analysis of marginal effects revealed differences between the base models.
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.

Contours of Alternative Policy Making in Venezuela
(Sage Publications Inc, 2014) Orhangazi, Özgür
The economic policies of the Venezuelan government in the last decade represent a significant departure from neoliberal orthodoxy. This departure consists of a focus on greater national autonomy, a return to some of the macroeconomic policies of earlier eras, and increased state involvement in the economy through interventions and social programs. While these policies have resulted in improved social indicators, they also have provided space for a set of "transformative" initiatives, including experiments with worker co-management, cooperatives, and participatory planning, all of which seek alternatives to the capitalist organization of the economy. Although the Venezuelan experience could be considered sui generis, especially with the economy's dependence on oil, a critical evaluation of the policies implemented in Venezuela would contribute to discussions on the alternatives to both neoliberal policies and capitalism in general. This paper provides an analysis of the break with neoliberal economic policies and of the transformative initiatives, as well as an evaluation of their achievements together with a discussion on their likely future path.

Time-Varying Fairness Concerns Delay and Disagreement in Bargaining
(Elsevier Science, 2018) Karagozoglu, Emin; Keskin, Kerim
We study an alternating-offers bilateral bargaining game where players may derive disutility from accepting shares below what they deem as fair Moreover we assume that the values they attach to fairness (i.e. their sensitivity to violations of their fairness judgments) decrease over time as the deadline approaches. Our results offer a new explanation to delays and disagreements in dynamic negotiations. We show that even mutually compatible fairness judgments do not guarantee an immediate agreement. We partially characterize conditions for delay and disagreement and study the changes in the length of delay in response to changes in the model parameters. (C) 2018 Elsevier B.V.

A Dynamic Game Theory Model for Tourism Supply Chains
(Sage Publications, 2021) Keskin, Kerim; Ucal, Meltem Şengün
This article contributes to the game-theoretic analysis of tourism supply chains. We start with a baseline model including three types of agents: (a) one theme park, (b) multiple accommodation providers, and (c) multiple tour operators. We investigate the strategic dynamics (i.e., collaboration and competition) embedded in a market with two different tourism supply chains, and then we extend our model to an infinite-horizon repeated game arguing that agents would face the same decision problem in each week of every holiday season in each year. We show how agents in a tourism supply chain end up with higher profits in any given period of a repeated game compared with their profits in the static version of the game.

Competition and Monopoly in the U.s. Economy: What Do the Industrial Concentration Data Show?
(Sage Publications, 2021) Davis, Leila; Orhangazi, Özgür
A recent series of academic studies, think-tank reports, and news articles shows widespread attention to rising industrial concentration and market power in the U.S. economy. In this paper, we focus on concentration in the U.S. nonfinancial corporate sector to make three contributions to the literature. First, we use examples from the debate on industrial concentration to show that there are often-divergent predictions in the theoretical literature surrounding the expected consequences of concentration and monopolization for nonfinancial firms. Second, we use industry-level concentration data to describe recent trends in average concentration. We show that, while concentration increases across the majority of industries after the late 1990s, the retail and information-services sectors are particularly key for understanding recent trends in average industrial concentration. Third, we link our industry-level analysis with firm-level data to describe the relationship between industrial concentration and nonfinancial corporations' profitability, markups, and investment. Consistent with the ambiguities in the theoretical literature, we find that these relationships are not uniform: while some highly concentrated industries confirm standard expectations with high markups, high profitability, and low investment rates, other highly concentrated industries earn lower-than-average markups and profits, suggesting that - in some industries - increased concentration and intensified competition may go hand in hand.

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.

Can Law Impose Competition? a Critical Discussion and Evidence From the Turkish Electricity Generation Market
(Pergamon-Elsevier Science Ltd, 2014) Oğuz, Fuat; Akkemik, K. Ali; Göksal, Koray
Electricity markets have undergone regulatory reforms since the early 1980s around the world. Technical analyses of these reforms usually pay lip service to the influence of politics over regulatory processes. Existing studies examine certain aspects of the market such as demand pricing and efficiency and they touch upon political issues only passingly when economic models cannot provide sufficient explanation This approach problematically takes politics as an ad hoc variable. This study shows that electricity is intrinsically a 'political good' and argues that any meaningful reform effort should take institutions as the starting point rather than a residual. The argument that politics has to be an endogenous variable in any model aspiring to explain behavior in electricity markets is demonstrated in the paper. The evidence for the political good character of electricity is found by examining the Turkish regulatory reform for Which it is argued that there is not a satisfactory relationship between expected and realized gains.

Macroeconomic and Institutional Determinants of Financialisation of Non-Financial Firms: Case Study of Turkey
(Oxford University Press, 2014) Akkemik, K. Ali; Özen, Şükrü
We observe that industrial firms in Turkey have shifted substantial amounts of working capital from production activities to the purchase of high-yield interest-bearing assets most notably public bonds to ensure immediate short-term interest revenues. Introducing the new and historical institutional literatures to the financialisation research this article empirically examines the influences of macroeconomic and institutional factors on non-financial firms' financialisation behaviour for the period 1990-2002. The findings from panel regression analyses using data from 41 firms listed on the Istanbul Stock Exchange indicate that both macroeconomic and institutional factors influence financialisation behaviour to different degrees. Turkish non-financial firms particularly engage in financialisation as a response to highly uncertain macroeconomic conditions. The findings indicate that the key characteristics of state-organised business system in Turkey such as firms' ties with the government and family ownership are not conducive to financialisation behaviour.

An Applied Analysis for Whether the Relation Between Innovation and Foreign Direct Investment Is Vicious for Turkey After the Early 1980s
(Elsevier Science Bv, 2016) Doruk, Ömer Tuğsal
The relation between innovation and foreign direct investment (FDI) is investigated in this paper by using time series Vector Autoregression (VAR) method. The main research question of the paper is whether FDI contributes on development of innovation in Turkey or vice versa. In Turkey after the structural transformations in Turkish economy export led growth is taken as vein that feeds to the economic development and thus importance of foreign direct investments have been increasing in the post-1980 period. The obtained findings show that FDI has not been contributing to innovation

Dependence on Imported Inputs and Implications for Technology Transfer in Turkey
(Springer New York, 2012) Akkemik, K. Ali
Trade and macroeconomic policies in Turkey evolved from import substitution to export promotion and liberalization of commodity and capital markets after 1980. During the 1980s and 1990s Turkey’s exports and imports and their shares in GDP demonstrated an increasing trend. The share of exports in GDP increased from 4.2% in 1980 to 20.3% in 2005 and that of imports rose from 11.4 to 32.2%. Import liberalization was accomplished during the second half of the 1990s and at around the same time direct price support for exports was abolished. © Springer Science+Business Media LLC 2012.

Bankaların Operasyonel Risk Yönetimi Olgunluk Seviyelerinin Oryos Endeksi ile Ölçülmesi ve Basel Iı Kriterlerine Göre Sermaye Yeterlilik Oranının Hesaplanmasında Bir Değişken Olarak Kullanılması
(Marmara Üniversitesi, Sos. Bil. Enst., 2012) Aykın, Hasan
Bu çalışmada, finansal kurumlarca önemi son yıllarda daha iyi anlaşılan ve gittikçe daha da artan operasyonel riskin yönetimi ele alınmış olup, sayısallaştırılması diğer riskler gibi kolay olmayan bu riskler için olgunluk modeli kullanılarak bankalar için “Operasyonel Risk Yönetimi Olgunluk Seviyesi” (ORYOS) endeksi hesaplanmıştır. Çalışmanın amacı iki noktada toplanmaktadır; bunlardan ilki, hesaplanan bu endeksle bankaların hem kendi hem de sektördeki seviyelerini daha iyi görebilmeleri, eksik noktalarını tespit edip kendilerine hedefler belirleyebilmeleridir. İkinci amaç ise bu endekse bağlı olarak belirlenecek “ORYOS Sermaye Yükümlülük Çarpanı” ile bankaların sermaye yeterlilik standart oranının hesabında bir düzeltme katsayısı olarak bankanın operasyonel risk yönetimi olgunluk seviyesinin dikkate alınmasını sağlayarak temel gösterge, standart yaklaşım ve alternatif standart yaklaşım kullanılarak yapılan sermaye yeterlilik hesabında daha gerçekçi bir ölçüm ortaya koymaktır.

Who Wants Left-Wing Policies? Economic Preferences and Political Cleavages in Turkey
(Routledge Journals, Taylor & Francis Ltd, 2020) Yagcı, Alper H.; Harma, Mehmet; Tekgüç, Hasan
We administer a survey of economic policy preferences to a representative sample of the Turkish voting-age population. We show that policy preferences are distributed in non-linear ways that are at odds with what could be expected from a conventional left-right division. We find that while objective socioeconomic differences are bad at predicting economic policy preferences, the latter are distinctly associated with politically salient cleavages built on religiosity and ethnicity. We also examine how preferences of each party's voters compare with party programmes.
