Three Essays on Economic Agents' Incentives and Decision MakingLee, Dongryul 04 June 2009 (has links)
This dissertation consists of three essays on theoretical analysis of economic agents' decision making and incentives. Chapter 1 gives an outline of the subjects to be examined in the subsequent chapters and shows their conclusions in brief.
Chapter 2 explores the decision problem of a superordinate (a principal) regarding whether to delegate its authority or right to make a decision to a subordinate (an agent) in an organization. We first study the optimal contracting problem of the superordinate that specifies the allocation of the authority and wage in a principal-agent setting with asymmetric information, focusing on two motives for delegation, "informative" and "effort-incentive-giving" delegation. Further, we suggest delegating to multiple agents as a way of addressing the asymmetric information problem within an organization, focusing on another motive for delegation, "strategic" delegation.
Chapter 3 analyzes the behavior of players in a particular type of contest, called "the weakest-link contest". Unlike a usual contest in which the winning probability of a group in a contest depends on the sum of the efforts of all the players in the group, the weakest-link contest follows a different rule: the winning probability of a group is determined by the lowest effort of the players in the group. We first investigate the effort incentives of the players in the weakest-link contest, and then check whether the hungriest player in each group, who has the largest willingness to exert effort, has an incentive to incentivize the other players in his group in order to make them exert more effort.
Chapter 4 examines the decision making of software programmers in the software industry between an open source software project and a commercial software project. Incorporating both intrinsic and extrinsic motivation on open source project participation into a stylized economic model based on utility theory, we study the decision problem of the programmers in the software industry and provide the rationale for open source project participation more clearly. Specifically, we examine the question of how the programmers' intrinsic motivation, extrinsic motivation, and abilities affect their project choices between an open source project and a commercial project, and effort incentives. / Ph.

Anxiety and lack of motivation as factors affecting success rates in bridging mathematicsSofowora, Samson Oluwaseun 11 1900 (has links)
The aversion to the study of mathematics and the resultant poor performance by students generally cannot be overemphasized and this still poses a great threat to the needed skills in the science, technology and commerce sector in South Africa. This study therefore tends to explore the importance of Mathematics to students and the economy globally by focusing on which contributive psychological factors are responsible for low performance in mathematics among Pre degree students as a case study.
In addition also, the teaching and learning strategies used in the classroom that will help curb mathematics anxiety among students will be looked into. Furthermore a test to ascertain if poor teaching methods or pedagogical content knowledge of mathematics’ teachers influence anxiety thereby leading to poor performance in mathematics will be carried out. By utilizing a mixed method approach, an integration of the qualitative and quantitative approaches, the study attempted to provide an insight into the poor performances in Mathematics by Pre-degree students in a Private Institution of higher learning by exploring the following affective domains: 1) Anxiety 2) Motivation (lack of either the Internal & External type) and also considering the teaching strategies adopted on the other hand.
The theoretical framework applied to this study was three fold in nature, namely, to investigate the nature of the relationship between mathematics anxiety and mathematics achievement on one side, secondly, to investigate the nature of the relationship between motivational orientation and mathematics achievement on the other side. Finally, it will investigate the relationship between teaching methods and mathematics achievement.
The major findings that emanated from this study were as follows: there is a strong impact of the affective factors (anxiety, beliefs, emotions and motivation) on mathematics learning and success rates among Pre-degree students in South Africa. This study shows the importance of affective factors (such as anxiety, negative attitude, lack of motivation) in determining the success and or failure of mathematics learning, with the intention of promoting and encouraging positive traits, attitudes and beliefs in the students.
The issue of teaching strategies was however not of a strong impact on success rates in bridging mathematics among the students as their lecturers were commended to be on top of their subject, but only that strategies to teaching mathematics must be dynamic, effective and varied as much as possible to meeting the students diverse learning styles . / Mathematics Education / M.
