    Analysing The Effect Of Coalition On Cost Structure For Turkish Liberal Electricity Market And Allocation Of Profit Surplus With Cooperative Game Theory
    (Institute of Social Sciences, 2019) Karaca, Nurtaç ; Ertemel, Sinan ; 565864 ; Economics ; Ekonomi
    In this study, retail electricity supply to the high consuming customers is analyzed using cooperative game theory to find the way of sharing the extra profit that is generated via cooperation. The physical electricity supply chain consist of producing, transmission, distribution and retail. The retail activity includes sale of electricity to end users. The retail activities are splited in two manners, the regulated and the liberal. In the liberal supply chain, consumers are eligible customers, who are entitled to select their suppliers as their consumption amount is over the electrical power amount defined by the Energy Market Regulatory Board. There are different types of market player in liberal retail electricity, as incumbent and non-incombent retail companies, electricity wholesalers, and power producers.

    Coalitional Deviation Proof Equilibrium In Nonatomic Games
    (Institute of Social Sciences, 2019) Ahmadov, Kamil ; Ertemel, Sinan ; 601970 ; Economics ; Ekonomi
    Nonatomic games are a useful way to model games with a large number players, which allows us to deal with a situation where each has a small influence on the outcomes by approximating a finite number of players by a continuum. However, in some instances, the results are problematic because there are implausible equilibria due to the strategic insignificance of the atomless players. Despite sometimes giving unrealistic results, nonatomic games are valuable because they may allow other parts of the game to use continuums. Therefore, it is important to develop an equilibrium concept for nonatomic games that gives players a small strategic influence on the outcome. This study provides an equilibrium refinement for nonatomic games, that allows nonatomic players to have a small, but positive, impact on the outcome. Particularly, we develop an equilibrium concept where nonatomic players can deviate from the pure strategy Nash Equilibrium in arbitrarily small groups. We introduce the coalitional deviation proof equilibrium, an equilibrium that is robust to arbitrarily small deviations.

    The Impact Of Interest On Income Inequality: An Empirical Investigation
    (Institute of Social Sciences, 2018) Maraşlı, Ozan ; Ertemel, Sinan ; 512646 ; Economics ; İktisat
    In this study, the effect of interest on income inequality is measured through the effect of real interest rate and the interest payments of the government on Gini index and income shares of income decile groups. By using a sample which includes the data of 26 countries between 1998-2014, we concluded that increases in both real interest rates and interest payments increases income inequality by increasing Gini coefficient and transferring a proportional income from the bottom and middle income groups — generally from bottom 60% — to the top decile and thus reducing social welfare, as this study reveals the exploitative nature of interest on the poor.
