Article Citation - WoS: 4Citation - Scopus: 4Modeling and Forecasting the Demand for Industrial Roundwood in Turkey: a Primary Econometric Approach(Wfl Publ, 2012) Kayacan, Bekir; Ucal, Meltem Şengün; Öztürk, Atakan; Bali, Ramazan; Koçer, Sacit; Kaplan, ErdemThis study is a primary econometric analysis to explore the factors explaining the changes in industrial roundwood demand in Turkey. The study also includes demand forecasts based on the econometric models proposed herein. We constructed two separate econometric models: one for national demand for domestically-produced saw log, and the other for national demand for domestically-produced non-sawlog industrial roundwood. Models were originally designed in multiplicative form. The original models are then converted into the log-linear form so that the relevant coefficients of the regression equations would immediately reflect the elasticities. Estimation of the model parameters are based on a panel data set of fifteen years (1995-2009) by twenty seven regional forest directorates in the country. In accordance with the maxim of less than the half of the 15 years period of data set, the demand forecasts are made for seven years beyond 2009. In view of the results, the explanatory power of the proposed models can arguably be deemed satisfactory especially considering the lack of earlier studies of this scale and scope. This consequently increases the credibility of the demand projections. Notwithstanding signs of the estimated parameters of the models are for the most part congruent with those expected in light of the economic theory and practice, some intriguing results are obtained. Perhaps most notably, while the sign of the estimated price elasticity of sawlog demand occurred unexpectedly positive, the variation in sawlog demand is explained to a considerable extent by the variation in the price of imported sawlog, hence an expected cross elasticity. Also notable is that the price of imported "fuelwood" holds a positive relationship with the national demand for domestic non-sawlog imdustrial roundwood, which is an expected cross elasticity since virtually all of the imported "fuelwood" is used as raw material for industry (e.g. chip and fiberboard industry). Finally, both models suggest overall boost in demand: yet an upper bound of 4.5 million m(3) for national demand for domestically-produced sawlog, and of 15 million m(3) for national demand for domestically-produced non-sawlog industrial roundwood can be expected by 2016.Article Citation - WoS: 6Citation - Scopus: 6Is Precarity a Fate for Women in Türkiye? Rethinking Energy Poverty From a Gender Perspective(Springer Heidelberg, 2023) Ucal, Meltem; Gunay, SimgeEnergy poverty is a challenging issue that hampers economic and sustainable development and lowers people's standard of living. While trying to understand energy poverty, it is imperative to focus on the disadvantaged individuals mentioned in the literature, as they are often most vulnerable to the problem. Focusing on them is essential to achieving sustainable development goals, especially in developing countries, particularly regarding poverty, energy poverty, and gender equality. Therefore, the paper aims to examine the impact of economic precarity on working-age females' energy poverty perceptions using 2018-2020 TURKSTAT-SILC pooled cross-sectional data. Our findings from the bivariate probit, multivariate probit and Bayesian bivariate probit models suggested that economic precarity has a disruptive role on females' energy poverty perceptions. Furthermore, inefficient energy use is an important factor in influencing females' perceptions of energy poverty. Females' inability to pay required housing expenses increases their perceived energy poverty. Therefore, social-welfare policies and energy policies should be considered together by the policymakers to resolve females' energy poverty problem to achieve a more sustainable future.Article Citation - WoS: 4Citation - Scopus: 3Perceived Happiness, Perceived Trust and Perceived Income Levels: the Case of the Reunified Germany(Savez Ekonomista Vojvodine, 2019) Ucal, Meltem Şengün; Günay, SimgeThis 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.Article Citation - WoS: 35Citation - Scopus: 41Turkish Public Preferences for Energy(Elsevier Science, 2018) Ediger, Volkan S.; Kirkil, Gökhan; Çelebi, Emre; Ucal, Meltem Şengün; Kentmen-Cin, ÇiğdemPublic concern over energy supplies prices sustainability and efficiency has emerged as a major issue around the world. Yet most of what we know regarding public opinion on energy comes from North America and Europe. This paper presents the results from the 2016 Turkish Public Preferences for Energy Survey which included 1204 respondents and examined Turkish residents' household energy consumption energy policy preferences and environmental concerns. The main findings were that Turkish citizens consider natural gas and electricity highly expensive view dependence on imported energy as Turkey's most pressing energy challenge and recognize the problem of climate change. This lends public support for wind and solar power but at the same time energy issues and the environment policies of political parties do not affect voting choices and political preferences.Article Citation - WoS: 21Citation - Scopus: 21A Dynamic Game Theory Model for Tourism Supply Chains(Sage Publications, 2021) Keskin, Kerim; Ucal, Meltem ŞengünThis 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.Article Citation - WoS: 13Citation - Scopus: 13Household Happiness and Fuel Poverty: a Cross-Sectional Analysis on Turkey(SPRINGER, 2021) Ucal, Meltem Şengün; Günay, SimgeIn recent years, self-reported happiness and fuel poverty have both become hotly-debated topics in the literature. Since both of them affect people's quality of life, they are certainly worth serious consideration. Therefore, this paper aims to conduct a household-level analysis on the association between happiness and fuel poverty taking advantage of other housing characteristics. We used ordered logit model utilizing Turkish Statistical Institute (TURKSTAT)'s 2014-2018 Life Satisfaction Survey (LSS) data for the analysis. Our dependent variable is household happiness. The results show that household fuel poverty is negatively associated with household happiness in Turkey. A positive association exists between becoming home-owner and household happiness in the country; however, it becomes mostly negative after considering odds ratios. On the other hand, there is a positive association between climbing income ladder and household happiness in the country. Also, the presence of men in households is found to be negatively associated with household happiness in Turkey. Our results imply a U-shaped association between age groups in households and household happiness in the country. Finally, we found that the association between an increase in household size and household happiness varies across each category of the independent variable. This is also the case for the association between number of rooms and household happiness as well as for the association between dwelling area and household happiness in Turkey.Article Citation - WoS: 2Citation - Scopus: 3An Econometric Analysis of Imported Timber Demand in Turkey(WFL PUBL, 2013) Kayacan, Bekir; Kara, Oğuz; Ucal, Meltem Şengün; Öztürk, Atakan; Bali, Ramazan; Koçer, Sacit; Kaplan, ErdemThis paper attempts to understand and explain determinants of Turkish demand for foreign timber imported to Turkey. Explanatory variables in the propounded model include price of imported timber price of domestically-produced sawlog as an imperfect substitute income per capita country population and capacity utilization rates (CUR's) and industrial production indices (IPI's) of forest industry sectors. For empirical purpose we used a time series data covering the 15-year period between 1995 and 2009. The econometric model set for there appears to be able to explain more than 96% of the variation in demand for imported timber with all of the parameter estimates except for population parameter being statistically significant. Estimation results confirm the existence of the price elasticity and substitute cross-price elasticity of demand for imported timber. Results also imply that the Turkish firms importing timber tend to consider domestic sawlog prices as much as even more than the price of foreign timber. The hypothesized effects of production changes in wood products and furniture industries on imported timber demand do not appear to be substantiated by this study which can partly be attributed to the partial method of measuring CUR's and IPI's. Meanwhile possible effects of income population and exchange rate index of the Turkish currency on the imported timber demand of the country are not evidenced by the empirical findings of this research. Finally our model forecasts ceteris paribus that by 2016 the level of Turkish demand for imported timber demand can reasonably be expected to exceed 2 million m(3)/year. This corresponds to the level of timber import observed in the years preceding the global economic crisis in 2009.Book Part Citation - Scopus: 6Energy and Sustainable Development From Perspective of Energy Poverty(Springer, 2021) Ucal, Meltem ŞengünEnd of poverty, the number one Sustainable Development Goal, focuses on ending all kinds of poverty all over the world. The elimination of all forms of poverty continues to be the biggest problem facing humanity today. The most important problems that have been encountered since the beginning of the energy use are the increasing risk of deterioration of energy supply, energy production and energy poverty. The problem of energy poverty among them is widely mentioned in the literature. In general, the studies on the subject focus on how the problem is defined worldwide, its size, its consequences, the obstacles to the elimination of the problem and some solution opportunities. The term “energy poverty” can refer to two different socio-economic issues, depending on the geographical scope of its application: energy affordability in higher income and developed states; inadequate access to “modern” energy services in most low income or developing countries”. Poor people pay a high price for the energy they use, either in cash or by labor. In addition, poor households spend more on energy than wealthy people, not only because their income is much smaller, but also because the fuels and equipment they use are much less efficient than modern fuels and equipment. No country has been able to diminish energy poverty to a great extent without increasing energy use. Decreasing the global inequality in energy is key to reducing income, gender and an inequality in other dimensions such as rural/urban income gaps. From this perspective, the importance of the relationship between energy poverty and sustainable development will be discussed by making comparisons by taking the country cases into consideration in the context of energy efficiency and renewable energy. The regional understanding of these concepts will also be discussed in this context.Master Thesis Kobi`lerde Kriz Yönetimi, Oluşabilecek Sorunlar ve Sorunların Giderilmesi için Uygulanabilecek Stratejiler(Kadir Has Üniversitesi, 2008) Kahya, Mehmet Enis; Şengün Ucal, MeltemKOBİ'ler, ülkemiz ekonomisinin dinamik birimleri olarak ekonomik ve sosyal sisteme olan katkıları nedeniyle, son yıllarda önem kazanmaya başlamışlardır. Toplumun tüm kümesini kapsayan ve her yerleşim birimine yayılmış olan KOBİ'ler, gerek kendi iç yapıları gerekse de dış çevreden kaynaklanan pek çok sorunla iç içe yaşamaktadırlar.Bu çalışmada kriz işletmeler için beklenilmeyen bir durumdur. Fakat gerçekte kriz bir süreçtir. Bu süreç içerisinde, KOBİ'ler farklı faktörlerin etkisi altında kalarak daha yüksek ölçüde belirsiz ve riskli bir ortamda faaliyetlerini sürdürmek durumunda kalmaktadırlar. Bu durum işletmeler açısından, örgüt içerisinde de krizlerin ve beklenmedik olumsuzlukların ortaya çıkamasına yol açmaktadır. Krizlerin olumsuz etkilerini azaltmak veya olumlu sonuçlara yol açabilecek şekilde yönetmek önemli bir avantaj olarak görülmektedir. Kriz yönetiminde etkin ve belirleyici unsurun krizin önceden tahmini ve doğru yönetsel kararların zamanında alınmasıdır. Bu nedenle; işletme sahipler ve/veya yöneticileri stratejik düşünce perspektifine sahip olmalı ve krizden en az zararla çıkabilmek için iç ve dış çevresinin analizini doğru biçimde yapabilmelidirler.Ülke ekonomisindeki durgunluk, yüksek enflasyon ve istikrarsızlık ve sık sık başvurulan değişen ekonomik tedbirler, sürprizleri genellikle tahmin edemeyen ve devlet tarafından yeterli danışmanlık hizmeti görülmeyen KOBİ'lerde başarısızlığa ve performans düşüklüğüne yol açabilmektedir. Bir kısmı bu sorunların üstesinden gelemeyerek ekonomik ortamdan çekilmekte, bir kısmı da yaşam mücadelesine devam edebilmektedir. Bununla birlikte, gelişmeleri ve değişmeleri yakından izleyebilen KOBİ'ler pek çok fırsatı değerlendirerek önemli avantajlar elde edip, büyüyüp gelişebilmektedirler.Article Citation - WoS: 1Citation - Scopus: 2The Nexus Between Migration and Environmental Degradation Based on Fundamental Climate Variables and Extreme Climate Indices for the Mena Domain(Elsevier, 2025) An, Nazan; Demiralay, Zekican; Ucal, Meltem; Kurnaz, M. LeventEnvironmental migration has recently become primary source of population growth and environmental degradation from extreme events has created the environmental refugee concept with a variety of manners affecting lives. For understanding of the environmental degradation impact on migration, a hybrid approach (regional climate modelling, RegCM4.4 and statistical modelling, ordered logit) has been applied for 65 countries in the Middle East and North Africa (MENA) for the periods of 2021-2050 and 2051-2080. It is aimed to examine how climate change affect migration by applying fundamental climate variables (i.e., maximum temperature, minimum temperature, and precipitation) and the control variables (i.e., the hot days, the tropical nights, and the dry days) in the MENA. While key findings indicate an increase in the minimum temperatures (Tmin) in future in all populous cities, the water amount may further decrease in the mid-latitude and Mediterranean with temperate climates due to precipitation change. While it may pose a high risk in the regions having experienced extreme temperatures e.g., tropical nights (Tn), it may further adversely affect ones not having experienced extremes. Considering statistically significant positive relationship between Tmin, and net migration rate (NMIG), and negative relationship between precipitation and NMIG, it may encourage migration to cooler regions.
