Achieving Turkey's Indc Target: Assessments of Nccap and Indc Documents and Proposing Conceivable Policies
(Mdpi, 2018) Alkan, Ayla; Oğuş Binatlı, Ayla; Deger, Cagacan
In 2015, Turkey submitted its Intended Nationally Determined Contribution (INDC) to the United Nations Framework on Climate Change Convention (UNFCCC) before the Paris Conference of the Parties (COP 21), expressing its intention to decrease emissions level at a rate of 21% from business as usual. This emissions reduction target is important as it is the first one for Turkey. However, Turkey faces unemployment problems and needs to sustain its growth. In this study, an Environmentally Extended Social Accounting Matrix (SAM), based on 2012 Input-Output data, was created, emissions reduction potentials of the National Climate Change Action Plan (NCCAP) together with the INDC were calculated, and alternative policies to reduce emissions to the target level and to boost the economy were proposed separately. The study finds that both the preparation and implementation of the previous national documents are problematic, and that Turkey was not meticulous about implementation of the climate mitigation policies in the previous national documents. The study also finds that reaching the emissions target with the INDC policies seems impossible and more conceivable policies are needed, and recommends that the INDC target and document itself should be revised substantially.
An Agent Based Modeling Approach To the Check Payments Among Smes in Turkey
(Bilgesel Yayincilik San & Tic Ltd, 2013) Arslan, İlker; Duman, Alper
Systemic risk and fragility became more important especially after the crisis of 2008. However, the burgeoning literature especially focuses on interbank and bank-firm credit networks. On the other hand, in developing countries, deferred check payments also compose another kind of credit networks and complement for the bank-firm credit lines. Check payments among SMEs even substitute for bank credits. Recent developments in Turkey offer an interesting setting in which we examine the fragility of check payment system. In this paper, we investigate whether the dramatic increase in nonpayments of checks have been due to the decline in growth or loosening of the legal sanctions. We analyze check payments using an agent based model. We can view check payments as a network structure where firms are nodes and check obligations are directed links. Firms' decision on whether paying their checks or not, depend on behavior of their neighbors and probable payoffs to their decisions. Our main finding is that lack of strict punishment can cause default cascades in check payment systems.

An Analysis of Turkey's Accession To the European Union
(Wiley, 2013) Oezguezer, Guel Ertan; Pensieroso, Luca
We build a two-country dynamic general equilibrium model to study whether European citizens would benefit from the eventual accession of Turkey to the European Union (EU). The results of the simulations show that Turkey's accession is welfare enhancing for Europeans, provided that Turkish total factor productivity (TFP) increases sufficiently after enlargement. In the benchmark model with no capital mobility, the Europeans are better off if the Turkish TFP increase bridges more than 21% of the initial TFP gap between Turkey and the EU. This figure increases to 33% when capital mobility is introduced.

Are There Really Bubbles in Oil Prices?
(Elsevier Science Bv, 2014) Balcilar, Mehmet; Ozdemir, Zeynel Abidin; Yetkiner, Hakan
The aim of this paper is to identify bubbles in oil prices by using the exponential fitting methodology proposed by Watanabe et al. (2007) [28,29]. We use the daily US dollar closing crude oil prices of West Texas Intermediate (WTI) covering the 1986:01:02-2013:07:09 and the Brent for the 1987:05:20-2013:07:09 periods. The distinguishing feature of this study from the previous studies is that this is the first study in the literature showing the existence of bubbles in crude oil prices. We found that there are four distinct periods of persistent bubbles in the crude oil prices since 1986. Two of these persistent bubbles are before 2000 and two of them are after 2000. We conclude that further research is needed to understand better how futures markets may impact the oil price formation. (C) 2014 Elsevier B.V. All rights reserved.

Can Differences in International Prices Measure Unequal Exchange in International Trade?
(Sage Publications Ltd, 2013) Subasat, Turan
This article discusses the limitations of using the deviations in international prices as a measure of unequal exchange. It argues that international prices are formed in a complex manner and lower international prices for low income countries cannot simply be considered as evidence for unequal exchange. The empirical validity of the measure is also questionable.

Clarification and Application of the Category Profit on Alienation
(Sage Publications Inc, 2023) Duman, Alper; Tonak, E. Ahmet
This article presents profit on alienation (POA) as one of the sources of profit in capitalist economies. In addition to identifying and situating POA among other profit flows, we have attempted to operationalize it in the real estate and finance sectors. In the empirical part of the article, we estimate POA in those sectors in Turkey for the period 2010-2019. The extent of estimated profits based on POA in those sectors is not insignificant. These findings confirm our position that utilizing POA in exploring capitalist dynamics would be a fruitful endeavor.JEL Classification: B3, B51, H27, G51

Consumption Convergence: Theory and Evidence
(Springer, 2024) Yetkiner, Hakan; Öztürk, Gamze; Tas, Bahar
This study aims to construct a sound theory of consumption convergence and empirically test its viability. To do this, we employ a Solovian framework in which the Keynesian exogenous savings-consumption allocation rule plays a crucial role. We demonstrate that consumption convergence performance is determined by both the average propensity to save (the indirect effect) and the average propensity to consume (the direct effect). In the empirical section, we use a system GMM estimator to test our consumption convergence equation on a panel data set of 177 countries and four income groups from 1970 to 2019. Our empirical findings indicate (i) absolute consumption convergence within high- and low-income country groups; (ii) strong evidence of conditional consumption convergence within high-, upper-middle-, and lower-middle-income groups; (iii) a robust and significant effect of the average propensity to save on the convergence process in high-, upper-middle-, and lower-middle-income groups; and (iv) a more robust and significant effect of the average propensity to consume in upper-middle- and lower-middle-income countries. In summary, we find that as income rises, the indirect impact plays a larger role in explaining consumption convergence, whereas the direct effect plays a smaller role. The policy implication of this conclusion is that policy makers in upper-middle- and lower-middle-income countries should restore the balance in the tradeoff between current and future consumption in favor of savings, as the former will harm consumption convergence within each middle-income group.

Convergence in Homicide Rates Across the European Union Countries: Toward an Effective and Genuine Security Union
(Sage Publications Inc, 2023) Adiyaman, Ezgi; Kasman, Saadet
This paper investigates whether homicide rates among the European Union (EU) member countries tend to converge over the period 1990 to 2018. We use the concept of beta-convergence proposed by Barro and Sala-i-Martin (1992) and employ the Generalized Method of Moments (GMM, hereafter) methodology for 2-years span panel data of 26 EU member countries. The results provide strong evidence for both absolute and conditional convergence of homicide rates across EU countries. Moreover, speed of homicide convergence is increased by the control variables, namely GDP per capita and unemployment rate. Hence, we conclude that the economic integration contributes to the process of convergence in homicide rates in the EU. JEL classification: O47; C23; K42

Convergence in Transportation Measures Across the Eu-15
(Springer, 2017) Beyzatlar, Mehmet Aldonat; Yetkiner, Hakan
This is the first study in the literature to investigate the convergence in transportation measures. To this end, we conjectured a transportation convergence equation and tested it via Difference GMM and System GMM methods, using 4-year span panel data from 15 European Union countries (EU-15) for the period 1970-2013. The results provide strong evidence for the existence of unconditional convergence among the EU-15 countries in two transportation measures, namely, inland freight transportation per capita, and inland passenger transportation per capita. The estimates show that the convergence is even stronger when control variables are used. We conclude that the income convergence of EU-15 in the process of economic integration is also strongly evident in the transportation sector.

Crude Oil Import Policy of Turkey: Historical Analysis of Determinants and Implications Since 1968
(Elsevier Sci Ltd, 2011) Ediger, Volkan S.; Berk, Istemi
Turkey is one of the most energy import dependent countries in the world, suffering deeply from the economic and strategic burdens of oil importation. Our purpose is to determine the factors behind the crude oil import policy of Turkey and to measure their contribution to a well-organized import strategy. We implemented a principle component analysis to construct an Oil Import Vulnerability Index (OIVI) based on four factors, which are crude oil import dependency of primary energy consumption, crude oil import bill as a share of Gross Domestic Product (GDP), non-diversification of import sources, and share of oil in total energy import. The contribution of these factors to the OIVI is found to be approximately equal. While an overall deterioration in the OIVI has been observed during periods of increasing oil prices, better diversification of oil import sources has lead to significant improvements. We suggest Turkish policy-makers implement sound policies, emphasizing diversification of crude oil import sources and reduction of the share of crude oil in primary energy imports to increase energy supply security. This study has also demonstrated that it is possible to construct an index representing crude oil vulnerability caused by import dependency. (C) 2011 Elsevier Ltd. All rights reserved.
Death as a Measure of Duration of Conflict
(Taylor & Francis Ltd, 2009) Akdede, Sacit Hadi; Oğuş Binatlı, Ayla
This paper introduces a new measure of conflict duration and argues that the number of deaths in a conflict can serve as such a measure. The paper demonstrates that there are information gains to this approach. The well-known conflict database of the International Peace Research Institute is compared with the database of the Center for Systemic Peace, which includes data on the number of deaths in addition to length of conflict. The number and distribution of conflicts vary; however, duration analysis based on the conventional measure of duration yields results that are robust over the above-mentioned datasets. We also show that the number of deaths, as a measure of duration, challenges some of the results based on the number of years as a measure of duration. In the 1990s, the duration of conflicts is significantly different from before when the duration measure is the number of years - we do not find a statistically significant distinction when the number of deaths is used. Ethnic conflicts have a longer survival time in terms of time but not in terms of number of fatalities.
The Determinants of the Secondary Market Price of Less Developed Countries' Debt
(Springer, 2008) Kazemi, Hossein S.
A present-value model of less developed countries' (LDC) debt is developed to understand the factors that affect the discount on the secondary market. LDC debt trades at a substantial discount on the secondary market. This paper investigates the determinants of the discount for a sample of 13 countries over a 9 year period. The findings show that debt-exports, foreign currency reservesimports and total debt service to exports ratios are significant determinants of the secondary market prices of LDC debt. The discount is higher in countries where debt-exports ratios are higher and is lower for those with lower foreign currency reserves-imports ratios. Concentration of debt with money center banks has a positive and significant effect on the secondary market price of debt.

Determinants of Turkey's Trade Flows: Gravity Model Approach
(Natl Acad Management, 2011) Bilici, Oe; Erdil, E.; Yetkiner, H.
This paper aims to determine (i) the trade flow equation for Turkey by using the gravity equation, (ii) the role of EU in Turkey's trade and whether the Customs Union of EU that Turkey entered in 1996 made a deviation in Turkey's trade flows. Turkey was a closed economy in late 1970s and has gradually become an open economy in these 30 years. During this period, Turkey followed globalization and regional integration strategies simultaneously. On the one hand, Turkey gradually opened its economy to the rest of the world. On the other hand, in the process of joining the EU, Turkey signed the Customs Union agreement. This makes Turkey a good case study of testing whether the regional integration decision has caused any deviation in the trade flow of the country. In this study, we first develop a gravity model and employ a panel dataset to verify whether it works in explaining Turkey's trade flow Next, we use this equation to test the importance of EU countries in Turkey's trade flow and whether the flow has been subject to deviation after the Customs Union agreement. Our findings suggest that although EU countries have always been important in Turkey's trade flow, Customs Union has not lead to any statistically significant deviation in Turkey's trade flow, hi that respect, the globalization effect has dominated the regional integration effect in the case of Turkey.

Do Liberal Trade Policies Promote Trade Openness?
(Routledge Journals, Taylor & Francis Ltd, 2008) Subasat, Turan
Although trade liberalization and trade openness are assumed to be strongly associated with each other and often used interchangeably, the empirical evidence has not been forthcoming. This article is an attempt to fill this gap. By investigating the link between trade openness and trade restrictions, it argues that while a negative link between various types of trade restrictions and trade openness is evident, the relationship is weak, statistically not always significant and there is no clear evidence that the removal of trade restrictions (trade-liberalization) invariably leads to improved trade openness.

Does Migration Contribute To Women's Empowerment? Portrait of Urban Turkey and Istanbul
(Routledge Journals, Taylor & Francis Ltd, 2019) Eryar, Sıtkı Değer; Tekguc, Hasan; Toktas, Sule
This article empirically investigates the impact of internal migration on women's empowerment in urban areas of Turkey. Based on data from a nationally representative household survey, we find that migration exerts a positive impact in urban settings through improvements in educational attainment and labor market outcomes. Migration contributes to women's empowerment by raising their education levels and lowering the gap in schooling between men and women. Migration also allows migrants, both men and women and particularly those with tertiary education, to access jobs and occupations in high wage regions like Istanbul. However, unlike in education, a gender wage gap persists even after migration.

Does Militarization Hinder Female Labor Income Share?
(Walter De Gruyter Gmbh, 2023) Elveren, Adem Yavuz
This study addresses the underexplored dimension of the relationship between military expenditures and gender inequality, drawing upon the insights of feminist security and international relations scholars. The influence of militarization on gender inequality is profound, manifesting itself significantly in both conflict and peacetime situations. The destruction of essential infrastructure further restricts women's access to vital resources. In peacetime, the convergence of militarization and patriarchy reinforces women's secondary roles in society, while higher military expenditures can divert resources from social spending, disproportionately affecting women and children reliant on public services. Despite extensive theoretical discussions, empirical studies on this nexus are limited. This paper contributes by presenting original evidence using a comprehensive dataset spanning 1991-2019, examining the Female Labor Income Share across over 100 countries. Findings reveal that militarization correlates with reduced the Female Labor Income Share, underscoring the urgency of addressing this critical linkage between militarization and gender inequality.
Does Size of Banks Really Matter? Evidence From Credit Default Swaps Market Data
(Bilgesel Yayincilik San & Tic Ltd, 2014) Arslan, Ilker; Oğuş Binatlı, Ayla
This study aims to discover whether markets take into account the phenomenon known as Too Big to Fail. Using Credit Default Swaps market data, which reflects the risk, markets attribute to banks, we calculate the default probabilities of banks over one, two, and three year periods. These results are then regressed with financial values such as total assets, total shareholders' equity and net income. Subsequently, the study is extended and the regression analysis repeated using Return on Assets as dependent variable. We find that markets place emphasis on profitability rather than size when pricing the riskiness of a bank. We conclude that the well-known concept of 'Too Big to Fail' cannot be considered as a concept with much validity, but the phrase 'Too Profitable to Fail' may provide a more accurate assessment of the situation.
