Innovation, Creativity, and Positive Psychological Capital: Examining the Relationships in Adolescents, Employees and Entrepreneurs

Innovation ist für das Überleben von Firmen und die Entwicklung von Ländern wesentlich, weil sie entscheidend für einen erhöhten Marktanteil und wettbewerbsfähigen Vorsprung ist (Baer & Frese, 2003; Dodgson, Gann & Salter; George & Zhou, 2011; Kleysen & Street, 2001). Gleichzeitig steht Innovation in engem Zusammenhang mit Erkenntnisfortschritten (West & Altink, 1996). Konzepte, die mit Innovation zu tun haben, beinhalten innovatives Verhalten und Kreativität. Kreativität ist die Produktion von neuen und nützlichen Ideen (Amabile, 1998), und Innovation ist die Umsetzung dieser neuen und nützlichen Ideen (Amabile, 1998; West, 2002). Diese Dissertation besteht aus fünf Abhandlungen, die sich mit den beiden Bereichen des Managements und der positiven Psychologie beschäftigen. Im Einzelnen verbindet die Dissertation Forschungen aus dem Bereich der positiven Psychologie mit Forschungen der Innovation, wie auch der pädagogischen Psychologie, um Antworten auf Forschungsfragen zu finden, die sich damit beschäftigen, was es ist, das die Kreativität von Mitarbeitern, Unternehmern und Jugendlichen und ihr positives psychologisches Kapital steigert (PsyCap). Luthans und seine Kollegen (2007, S.3) definieren das psychologische Kapital oder PsyCap als „den positiven psychologischen Entwicklungszustand einer Einzelperson, welcher wie folgt beschrieben wird: (1) Selbstvertrauen haben (Selbstwirksamkeit), um sich Herausforderungen zu stellen und den notwendigen Aufwand aufzubringen; (2) Eine positive Attribution (Optimismus) in Bezug auf gegenwärtigen und zukünftigen Erfolg; (3) Ziele anstreben und, wenn notwendig, die Wege zu den Zielen ändern, um Erfolg zu erreichen (Hoffnung); (4) Im Falle von Problemen und Missgeschicken standhalten und wieder zurückkommen (Widerstandsfähigkeit), um Erfolg zu erreichen.“

Compositional hypotheses of subcompositional stability and specific perturbation change and their testing

In standard multivariate statistical analysis common hypotheses of interest concern changes in mean vectors and subvectors. In compositional data analysis it is now well established that compositional change is most readily described in terms of the simplicial operation of perturbation and that subcompositions replace the marginal concept of subvectors. To motivate the statistical developments of this paper we present two challenging compositional problems from food production processes. Against this background the relevance of perturbations and subcompositions can be clearly seen. Moreover we can identify a number of hypotheses of interest involving the specification of particular perturbations or differences between perturbations and also hypotheses of subcompositional stability. We identify the two problems as being the counterpart of the analysis of paired comparison or split plot experiments and of separate sample comparative experiments in the jargon of standard multivariate analysis. We then develop appropriate estimation and testing procedures for a complete lattice of relevant compositional hypotheses

The agreement between ipsative and normative questionnaires using compositional data analysis techniques

The main instrument used in psychological measurement is the self-report questionnaire. One of its major drawbacks however is its susceptibility to response biases. A known strategy to control these biases has been the use of so-called ipsative items. Ipsative items are items that require the respondent to make between-scale comparisons within each item. The selected option determines to which scale the weight of the answer is attributed. Consequently in questionnaires only consisting of ipsative items every respondent is allotted an equal amount, i.e. the total score, that each can distribute differently over the scales. Therefore this type of response format yields data that can be considered compositional from its inception. Methodological oriented psychologists have heavily criticized this type of item format, since the resulting data is also marked by the associated unfavourable statistical properties. Nevertheless, clinicians have kept using these questionnaires to their satisfaction. This investigation therefore aims to evaluate both positions and addresses the similarities and differences between the two data collection methods. The ultimate objective is to formulate a guideline when to use which type of item format. The comparison is based on data obtained with both an ipsative and normative version of three psychological questionnaires, which were administered to 502 first-year students in psychology according to a balanced within-subjects design. Previous research only compared the direct ipsative scale scores with the derived ipsative scale scores. The use of compositional data analysis techniques also enables one to compare derived normative score ratios with direct normative score ratios. The addition of the second comparison not only offers the advantage of a better-balanced research strategy. In principle it also allows for parametric testing in the evaluation

Testing for Hidden Information and Action in Automobile Insurance Market

I test the presence of hidden information and action in the automobile insurance market using a data set from several Colombian insurers. To identify the presence of hidden information I find a common knowledge variable providing information on policyholder s risk type which is related to both experienced risk and insurance demand and that was excluded from the pricing mechanism. Such unused variable is the record of policyholder s traffic offenses. I find evidence of adverse selection in six of the nine insurance companies for which the test is performed. From the point of view of hidden action I develop a dynamic model of effort in accident prevention given an insurance contract with bonus experience rating scheme and I show that individual accident probability decreases with previous accidents. This result brings a testable implication for the empirical identification of hidden action and based on that result I estimate an econometric model of the time spans between the purchase of the insurance and the first claim, between the first claim and the second one, and so on. I find strong evidence on the existence of unobserved heterogeneity that deceives the testable implication. Once the unobserved heterogeneity is controlled, I find conclusive statistical grounds supporting the presence of moral hazard in the Colombian insurance market.
