Ohne ZusammenfassungHerrn Doz. Abele und Herrn Dr. Beinsen bin ich für die kritische Durchsicht dieser Arbeit zu Dank verpflichtet. Doz. Abele hat mir vor allem allgemeine Hinweise zum Stand der Theorie gegeben, die mich zu dieser Arbeit erst so recht anregten.     

Educational Development and Labour Markets

For over a century and a half, there have been cyclical phases ofsaturation and shortage in the numbers of students enrolled at German and Prussian universities. Starting from thisobservations, this article constructs a neoclassical glutting theory. A two-fold hypothesis is put forward. Firstly,the behaviour of students in their choice of curriculum depends on the expected rewards. Indeed, the allocation of studentsto the various faculties depends on the comparative yields of the latter in terms of expected earnings and job availabilityin the corresponding professional sectors. Thus, the rewards expected by a student are represented by the earnings on thelabour market at a given moment and that he or she considers to be sustainable in time. Secondly, an attraction phenomenonmay appear for certain curricula when a shortage occurs in different professional sectors. Once the shortagehas been made up, the demand effect continues as a result of delay in the perception of the situation by young people.This may gradually lead to comparative over-production of qualifieduniversity leavers. This unbalanced situation diverts new cohorts ofstudents to other sectors ofeducation and may cause a new shortage, finally resulting in acyclical movement modulated according to job availability.

Two-moment decision models and rank-dependent utility

This paper extends results on the consistency of two-moment decision models with expected utility to rank-dependent utility preferences. The representations of expected utility and rank-dependent utility by --preferences have very similar comparative statics properties for linear distribution classes, except for the behavior with respect to small independent risks.I thank Soo Hong Chew for helpful discussion and three anonymous referees for valuable comments.     

Forward-neutral valuation relationships for options on zero coupon bonds

This paper extends the literature on Risk-Neutral Valuation Relationships (RNVRs) to derive valuation formulae for options on zero coupon bonds when interest rates are stochastic. We develop Forward-Neutral Valuation Relationships (FNVRs) for the transformed-bounded random walk class. Our transformed-bounded random walk family of forward bond price processes implies that (i) the prices of the zero coupon bonds are bounded below at zero and above at one, and (ii) negative continuously compounded interest rates are ruled out. FNVRs are frameworks for option pricing, where the forward prices of the options are martingales independent of the market prices of risk. We illustrate the generality and flexibility of our approach with models that yield several new closed-form solutions for call and put options on discount bonds.     

Changing investment styles: style creep and style gaming in the hedge fund industry

Notwithstanding their common features, hedge funds remain an extremely diverse asset class. Information on fund styles is important for numerous purposes, such as portfolio construction, performance attribution and risk management. With fund self‐declaration being prone to (strategic) misclassification, return‐based taxonomies grouping funds along similarities in realized returns provide a useful alternative. We provide a consistent classification system of homogeneous groups of hedge funds based on self‐organizing maps. Whereas some fund categories such as managed futures are largely consistent in their self‐declared strategies, others, especially so‐called ‘equity hedge’ funds, display no or very limited return similarities. Furthermore, we also find evidence of fund managers performing undisclosed changes of their trading style over time. Those funds that misclassified themselves once are particularly likely to change their trading style again. Although style self‐declaration can, therefore, be quite misleading, our results indicate that hedge funds do not misdeclare their style strategically to improve their relative performance.

Intuition and rationality in intrapreneurship and innovation outputs: The case of health professionals in primary health care

The aim of this article is to explore the role of cognitive styles and intrapreneurship in health professionals’ innovation outputs, as well the mediated effect of intrapreneurship between cognitive styles and innovation output. This study used the survey method of data collection, through a self-administered questionnaire. Partial least square structural equation modelling method was used to analyse the result of the sample of 209 professionals of primary health care providers in Northern Portugal. Our findings reveal that cognitive style plays a significant role in intrapreneurship and innovation outputs, which are mediated by intrapreneurship. In particular, health care professionals with the rational cognitive style are likely to be more of a intrapreneur and innovative as compared to those with a intuitive cognitive style. Promoting intrapreneurship is crucial for successful innovation outputs. This study reveals that an understanding of the cognitive style of the health care professionals can help managers allocate appropriate individuals to different healthcare tasks. Our primary contribution to theory has been to highlight the importance of cognitive styles in intrapreneurship and innovation within the context of primary health care organizations.

The Return Performance of Cubic Market Model: An Application to Emerging Markets

This article studies the performance of the high-order moment capital asset pricing model (CAPM) market models in emerging markets. We apply the cubic market model (4-moment CAPM) to 16 emerging market stock indices ranging from January 2010 to September 2015. Performance of the model is evaluated through the Fama and MacBeth’s two-step regression and through different corrections proposed in the literature, as well as generalized method of moments (GMM) estimation. According to Fama–MacBeth’s procedure, CAPM, the quadratic and cubic market models seem to be insignificant for the analyzed sample; however, the GMM estimation shows that quadratic model is valid for Indian, Polish, and Thai country indices, whereas cubic market model is accurate for Indian country index.
