The role of fixed entry costs in an evolutionary entry game with bertrand players

Soytaş, Uğur
This paper analyzes the role of fixed costs in an evolutionary entry game with Bertrand players. A stable state fails to exist when entry is free, regardless of whether capacity constraints are present or not. When a fixed entry cost is introduced, there is a unique evolutionarily stable strategy (ESS) identical to the ESS outcome of Soytas and Becker (2003) and resembling the separating equilibrium of Milgrom and Roberts (1982). The unique ESS emerges even when capacity constraints are imposed. However, the fixed cost must be sufficiently large for the ESS to prevail if the incumbent has capacity limitations.

This thesis analyzes the implications of big data on subjectivity with a genealogical approach through the case of Cambridge Analytica. The changes in the epistemology, episteme, rationalities and the regimes of truth as a result of data pervasion are discussed. The statistics and the cybernetics as the antecedents of data politics are reviewed and data politics as a new mode of power is put forward. The targets, the objectives, the technologies and the rationalities of this new mode of power are analyzed. ...
The Nature of financial innovations : a post-Schumpeterian analysis
Bulgurluoğlu, Pelin; Akdere, Çınla; Department of Economics (2013)
This thesis analyzes the nature of financial innovations by taking a post-Schumpeterian approach. The aim of this thesis is to show that Schumpeter’s analysis of entrepreneurial innovation, which takes place in the real economy, proposes also a theoretical framework for understanding the dynamics of financial innovations. Therefore, it suggests that Schumpeterian notion of innovation can be used as a guide in analyzing the dynamics of financial innovations today. In this respect, through the analysis of fin...
An inspection approach for conceptual models in notations derived from UML: A case study
Tanrioever, Oezeguer; Bilgen, Semih (2007-11-09)
This paper presents an overview of a proposed framework for improving the quality of conceptual models developed in notations derived from UML. To this aim, wellness properties of a UML model are described shortly. Through a case study, we show that an ad hoc inspection process in accordance with this framework can be defined and performed depending on the conceptual modeling notation and typical real models. This study showed us that the application of the defined inspection process, which adopts concepts ...
The complexity of topological conjugacy of pointed Cantor minimal systems
Kaya, Burak (2017-05-01)
In this paper, we analyze the complexity of topological conjugacy of pointed Cantor minimal systems from the point of view of descriptive set theory. We prove that the topological conjugacy relation on pointed Cantor minimal systems is Borel bireducible with the Borel equivalence relation Delta(+)(R) on R-N defined by x Delta(+)(R)y double left right arrow {x(i):i is an element of N} = {y(i):i is an element of N}. Moreover, we show that Delta(+)(R) is a lower bound for the Borel complexity of topological co...
The effect of design patterns on object-oriented metrics and software error-proneness
Aydınöz, Barış; Bilgen, Semih; Department of Electrical and Electronics Engineering (2006)
This thesis study investigates the connection between design patterns, OO metrics and software error-proneness. The literature on OO metrics, design patterns and software error-proneness is reviewed. Different software projects and synthetic source codes have been analyzed to verify this connection.
