The network economics: case studies
(Kadir Has Üniversitesi, 2013) Ucal, Meltem; Ucal, Meltem
This thesis basically explores the definition of networks different types of networks such as social economic information technological and the positive and negative externalities which occur as the result of the interaction of the networks with the environment. By emphasizing the positive relationship of technology social networks and network economics this paper gives current example from ecommerce sector in the world and tries to be critical to the network economics which may lead to interests for further discussions by those doing research in the same area. This paper also contains the case analyses as the examples of e commerce that is the top point of the economic networks today. The cases Ebay and Alibaba.com show the potential of the network economy and Harley Davidson case focuses on the social effects of the networks. -- Abstract'tan.

Housing Prices in a Market Under Years of Constant Transformation: A County-Based Analysis of Istanbul
(Cracow Univ Economics, 2020) Ucal, Meltem; Kaplan, Uğur
Objective: The objective of the article is to present a comprehensive approach to analysing Istanbul's housing prices, using a hedonic price model with a large dataset and a single variable for locational attributes. Research Design & Methods: The analysis of consequent housing prices in Istanbul's counties with hedonic price modelling and the extrapolation of results by comparing the prices to the human development level of counties. We use multiple regression and Ordinary Least Squares (OLS) methods to estimate two semi-log hedonic price models for two time periods. Findings: The relationship between socioeconomic development levels and housing prices varies for counties under different urban transformation processes. Implications & Recommendations: The results are useful for the housing price analysis in Istanbul. The housing prices appear to follow the socioeconomic development level of the county in which a house is located, thus showing variations between different counties. The relationship between housing prices and urban transformation processes should be approached with caution by policymakers, as the outcomes may disturb both the sociological and economic balance in the long run. Contribution & Value Added: The study contributes to the existing research on housing price analysis by interpreting locational attributes as a whole and housing research at large by combining hedonic price modelling and case study methods.

Food to Grid: Developing a Multi-Value renewable energy investment ecosystem
(Pergamon-Elsevier Science Ltd, 2022) Ucal, Meltem; Efthimiadou, Aspasia; Ucal, Meltem
The paper is focused on building a multi-source small-scale facility that shall be focused on increasing the Renewable Energy Sources share into the grid and at the same time meet the energy, and fresh food needs of the small community that shall operate. The developed facility that shall be utilised is introducing, in practice, a sustainable Energy-Food nexus plan that can be implemented and put into action by the independent power producers and municipalities, meeting also the goal of supporting the grid (a Food to Grid approach). A case study was tested, and it was found that a scheme that couples the curtailed power with a potential mass deployment of vertical farms is beyond sustainable and even with very low marginal price-earnings and the minimum price offered for vertical farms, under specific scenarios can have a full payback in 14 years as an investment. However, in the average optimal case, the investors can get their investments back in 7 years, with an internal rate of return of 17%.
The role of climate change in the energy policies of the European Union
(Kadir Has Üniversitesi, 2022) Demirkıran, Vildan; Ucal, Meltem; Ediger, Volkan; Meltem Ucal
One of the key factors for economic development and increasing the welfare level of the people is energy. Developed and developing countries depend on fossil fuel resources to meet their energy demand. The need for fossil energy sources, unevenly distributed throughout the world, is increasing daily. However, the rapid depletion of reserves and their short life span threaten countries in terms of energy supply. One of these countries is the European Union, which is a supranational organization. The Union, which ranks first in energy imports, meets more than half of its energy needs from fossil resources. In the past, the problems experienced in energy supply due to international oil crises and political instability in the countries on which it is dependent on energy forced the Union to produce a new energy policy. In the 1990s, the issue of climate change, which emerged as a result of the excessive use of fossil fuels, came to the fore, and the goal of reducing carbon emissions, which reached dangerous levels, to pre-Industrial Revolution rates brought a new dimension to the energy policies of the European Union. In order to ensure energy supply security, reduce dependence on fossil fuels, and produce sustainable and environmentally friendly energy, the EU develops new policies. Aiming to be a climateneutral continent by 2050, the Union plans to obtain most of its energy needs from renewable sources and low-carbon technologies. In this study, the change in energy policies since the establishment of the EU, the role of climate change in policy making, how far the EU is in carbon emission reduction targets, the role of the EU in global climate leadership and future plans will be discussed.

Is precarity a fate for women in Türkiye? Rethinking energy poverty from a gender perspective
(Springer Heidelberg, 2023) Ucal, Meltem; Gunay, Simge
Energy 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.
The relationship between happiness and perceived income inequality as well as some social indicators: a comparative analysis on Turkey and selected european countries
(Kadir Has Üniversitesi, 2016) Ucal, Meltem; Ucal, Meltem
in recent years the relationship between happiness and income distribution has become an important issue in the economics literature. Underlying reason of this situation is the widening income gap between the rich and the poor since 1980s. Several studies have traced the link between happiness and income inequality especially since the last two decades. it is also very important to study “perceived” income distribution and inequality because they may show different approaches to income distribution and inequality from many individuals. The aim of this study will be to explore the relationship between perceived happiness level and perceived income inequality in Turkey and the other selected OECD countries using the World Values Survey data. The main question will be whether and to what extent perceived income inequality affects happiness level of individuals who live in those countries. in addition some social characterictics and socio-demographic variables will be used to learn whether they affect people’s happiness or not in Turkey and other selected countries more or less than their perceptions to income inequality. Generalized ordered logit model analysis will be used in the study because it fits to the nature of our data. This study is expected to contribute to the literature in the sense that it will give relevant people a point of view about the relationship between perceived happiness of people who live in selected countries and perceived income inequality as well as selected variables because a similar comprehensive and comparative study has not been found in the literature which especially addresses Turkey yet. At the end of the empirical analysis it is seen that perceptions to income inequality impact on happiness level positively however its impact is weaker than other social and demographic variables in the analysis.
