Confidence enhanced performance : does it exist and if so how does it work?
(2010) Murad, Zahra
We empirically test and investigate the psychological mechanism behind the theory of Confidence Enhanced Performance (Compte and Postlewaite, 2004). This theory suggests that if confidence enhances performance, then people will benefit from having the commonly observed tendency to discount past failures and be overconfident. We test this hypothesis using three tasks which require different cognitive abilities. Our findings are partially supportive of the theory. However, we cannot conclude that any of our confidence variables significantly and positively affect performance. Only in one task (the Picture Recall task) we find that enhanced mood level positively affects performance. The view that people are generally overconfident when performing tasks with imperfect feedback is not upheld. Furthermore, there seem to be strong task differences in both levels of confidence and the effects of psychological variables on performance.

Designing a decision support system for debt payment planning under inflation
(1994) Özkan, Mehmet
Computer technology has been developed very rapidly in recent years and now computers are even replacing human in some areas. Use of judgment, however, is still very important in many other fields. Financial management is one of the areas that need managerial judgment and intuition while making decisions. In this study, we propose a methodology for designing a system to assist the decision maker (DM) in using his judgment to make effective decisions. The system also has to facilitate and enhance learning since judgment is excelled by experience. We specificly analyze decisions regarding the Debt Payment Planning (DPP) problem. This problem, which may be briefly stated as ‘development of an operational plan for the liquidation of debts’, is a new problem and does not exist in the literature. The analyses are conducted keeping in mind that the uncertainty of the financial environment and burden of inflation increase the complexity of the decisions. A model which we call, ‘Growth Model of Debt’ will be used in the analyses and a sample session will be shown to provide a clear understanding of the system operation.

A supplier evaluation and selection system in Turk Tractor Factory
(1995) Aktaş, Pınar
The world is changing toward globalization. Therefore, the markets are becoming more and more competitive each day. It is harder for companies to be good performers. Realizing this fact, they are trying to have the highest contribution from different sources they have. This includes the financial sources as well as people. However, there is an important success key that should not be disregarded. These are the suppliers where 40- 60% of the total sales of manufacturing companies are spent. Knowing this, the companies should choose and use their suppliers at the highest maximum performance. This study establishes a system for the evaluation and selection of suppliers where an application will be carried out in a company in the automotive sector, Turk Tractor Factory.
