Overconfidence in finance with different domains: an interdisciplinary experimental approach

2014-03-01
Behavioral and experimental finance literature has grown by leaps and bounds in recent years. However, much work remains to be done in the field. In detecting behavioral biases and their effects on decision making process, experiments are very advantageous in that it is possible to obtain valuable findings about the biases of individuals in controlled laboratory settings. The purpose of this study is to search for the overconfidence bias of UK subjects and investigate whether overconfidence is domain specific. Results indicate that people are generally overconfident. Most of them see themselves above average and overestimate precision of their knowledge. In addition, it is found that individuals are less overconfident in the domain of finance.

Comparative study of risk measures
Ekşi, Zehra; Körezlioğlu, Hayri; Department of Financial Mathematics (2005)
There is a little doubt that, for a decade, risk measurement has become one of the most important topics in finance. Indeed, it is natural to observe such a development, since in the last ten years, huge amounts of financial transactions ended with severe losses due to severe convulsions in financial markets. Value at risk, as the most widely used risk measure, fails to quantify the risk of a position accurately in many situations. For this reason a number of consistent risk measures have been introduced in...
Dynamic complex hedging and portfolio optimization in additive markets
Polat, Onur; Hayfavi, Azize; Department of Financial Mathematics (2009)
In this study, the geometric Additive market models are considered. In general, these market models are incomplete, that means: the perfect replication of derivatives, in the usual sense, is not possible. In this study, it is shown that the market can be completed by new artificial assets which are called “power-jump assets” based on the power-jump processes of the underlying Additive process. Then, the hedging portfolio for claims whose payoff function depends on the prices of the stock and the power-jump ...
Additional factor in asset-pricing: Institutional ownership
Uğurlu-Yıldırım, Ecenur; Şendeniz Yüncü, İlkay (Elsevier BV, 2020-01-01)
In this paper, we hypothesize that institutional investor variable is a proxy for some systematic risk factors, which should be incorporated into the asset-pricing model. Mimicking portfolio for institutional ownership, called IMI (Institutional minus Individual), is constructed. Including IMI to the Carhart's 4-factor model captures the common variations in returns better than all other models that are tested. Consistent with the literature, the new 5-factor model improves mispricing mostly in portfolios i...
The characteristics of financial innovation in developing countries : the case of Turkey
Kılıçaslan, Seda; Cömert, Hasan; Department of Science and Technology Policy Studies (2019)
Financial innovations are one of the important factors affecting the development of financial markets and have attracted more attention in the literature especially after the 1980s. In the existing literature, only a few studies investigate financial innovation processes in developing countries. The main purpose of this study is to investigate the factors influencing the emergence and development processes of financial innovations in Turkey. Thus, it is aimed to fill the gap in the development process of fi...
Credit risk modeling and credit default swap pricing under variance gamma process
Anar, Hatice; Uğur, Ömür; Department of Financial Mathematics (2008)
In this thesis, the structural model in credit risk and the credit derivatives is studied under both Black-Scholes setting and Variance Gamma (VG) setting. Using a Variance Gamma process, the distribution of the firm value process becomes asymmetric and leptokurtic. Also, the jump structure of VG processes allows random default times of the reference entities. Among structural models, the most emphasis is made on the Black-Cox model by building a relation between the survival probabilities of the Black-Cox ...
