Essays on Credit and Reserves

2022-6
Düzçay, Güney
This thesis consists of three separate essays that concern some challenges in the monetary sphere of developing countries. The theme of the first essay is the low level of credit creation capacity in developing countries. It focuses on a particular impediment on the credit creation capacity, which is the hierarchical nature of monetary (financial) instruments. The concept of the hierarchy of money is put to use in order to discuss the structural forces that constrain domestic currency denominated credit creation and lead to massive foreign exchange reserves accumulation. The theme of the second essay is the identification of credit booms, which are arguably the most prominent cause of severe financial distress episodes and crises. This essay particularly concentrates on the time-specific aspects of credit booms and develops a modified method for credit boom identification with that purpose. Then, this novel method is applied for a large data set with the purposes of documenting the time-specific and country-group characteristics of credit booms and their relationships with banking crises. The third essay is related to the reserve management and strategic asset allocation for central banks in developing countries. This essay focuses on developing an alternative framework for strategic asset allocation among multiple currencies by using common portfolio optimization methods. It suggests using a basket-currency (consisting of major currencies) as a numeraire by providing a formulation for constructing a basket with desired properties, and then presents the performance of optimization results in comparison to general practices.

An Analysis of the social and solidarity economy and Post WW II development theories

This thesis seeks to analyze the relationship between social and solidarity economy and post-World War II development thinking. Social and solidarity economy is a notion which is highly contested.

Two essays on ambiguity and asset pricing
Şahin, Baki Cem; Danışoğlu, Seza; Department of Business Administration (2019)
This thesis consists of two essays on the impact of ambiguity on asset pricing. In the first essay, we provide a detailed review of theoretical models incorporating ambiguity into both decision-making and asset pricing models. In the framework of these discussions, we derive ambiguity indices and we provide both a comparison among themselves and an analysis showing the impact of ambiguity on asset pricing for Turkey. Our results confirm the existence of impact of ambiguity on asset returns even it is not st...
A Critical inquiry into the demarcation of logical constants
Beygu, Tankut; Grünberg, Teo; Department of Philosophy (2013)
The dissertation aims to set out a methodological framework conducive to further research into the demarcation problem of logical constants through a critical examination of the principal proposals for the problem. Logical constants should be characterised so as the essential values of logic, i.e., necessity, normativity and formality, are secured. Formality is central to the proposed framework in consideration of its relation to validity; necessity and normativity are established with reference to formalit...
