11	Decision-Making in Markets Ngangoue, Kathleen Maryse 28 December 2017 (has links) Diese Dissertation erforscht, auf welchen unterschiedlichen Wegen Informationsverarbeitung Investitionsentscheidungen beeinflusst. Auf der Basis kontrollierter Laborexperimente wird untersucht, wie Entscheidungen mit der Art der Information sowie mit dem Entscheidungskontext variieren. Im ersten Kapitel legt ein Experiment die Schwierigkeit mit hypothetischem Denken bzw. mit dem Lernen aus hypothetischen Ereignissen offen. Im Kapitel Zwei untersucht ein anderes Experiment, wie Informationsverarbeitung die Reaktionen der Investoren auf Ambiguität verändert, denn ein eindeutiges, optimales Lernverhalten gibt es unter Ambiguität nicht. Das letzte Kapitel stellt anhand desselben Experiments die Unabhängigkeit zwischen dem Lernprozess und den Risikopräferenzen in Frage. / This dissertation investigates various channels through which information processing affects investment decisions. Controlled laboratory experiments allow for studying how subjects’ decisions vary with the type of information and the decision-context. The experiment in the first chapter discloses the difficulty with contingent reasoning, i.e. learning from hypothetical events. A different experiment in Chapter Two analyzes how information processing changes investors’ reactions to ambiguity—an environment with multiple rational learning rules. Using the same experiment, the last chapter questions the independence between belief updating and risk preferences.

12	Pathways of out-of-school youth and their re-entrance into the education training and development system or the labour market Dube, Andile Laureth Maletsatsi 06 June 2011 (has links) The study is an investigation into the pathways of out-of-school youth and their re-entrance into the Education Training and Development (ETD) system or the labour market. In the study the pathways of youth who dropped out of school between grades 1 and 11 are traced as they seek re-entrance to the ETD system, or entrance into the labour market. Particular attention was given to the factors that determine the choices that dropouts make either in re-entering the ETD system or entering the labour market. An analysis of the experiences of the interviewed sample of dropouts is presented. The study employs a qualitative research methodology using interviews to elicit the experiences of dropouts and school managers. The participants (young people and three school principals) were selected through snowballing from a township south of Durban. Individual and focus group interviews were held. The findings provide evidence of the value of investing in education, as suggested by the youth. This is in line with the human capital theory framework that suggests that there are major benefits to investing in education. The study is concluded by suggesting the need for second chance education in South Africa. / Thesis (PhD)--University of Pretoria, 2011. / Education Management and Policy Studies / unrestricted Drop out and drop-in Investing in education Human capital Information poverty Youth pathways School-to-work transitions Youth transitions Re-entry experiences Second chance education Rational decision making theory Successful destinations Education policy UCTD
