A Conditional Variance Model for Daily Deviations of an Exchange Rate

A model for the distribution of daily deviations of an exchange rate is suggested. The distribution is Gaussian with a variance that depends on previous deviations. The model is applied to the exchange rate of the U.S. dollar to special drawing rights.     

Trust in surveys and games – A methodological contribution on the influence of money and location

This paper explores methods to study trust. In a variety of settings, answers to survey questions and choices in a trust game are obtained from student sample pools. Some subjects are approached by mail and execute their task at home whereas others participate in classroom experiments. No differences between the results obtained by these methods are observed. Furthermore, one additional group plays the trust game with purely hypothetical payments, and another receives random lottery payments. This changes trust behavior dramatically, whereas trustworthiness is unaffected. Subjects without any financial incentives exhibit less trust and their trust choices are significantly correlated with survey trust answers. There is no such correlation for the corresponding choices with real payments.     

The study of mental distress and the (re)construction of identities in men and women with experience of long-term mental distress

This article explores the possibility of using a theoretical framework drawn from disability studies in the field of mental health, and the study of identity (re)construction in the recovery process. In this PhD project, 33 narratives were analysed using framework analysis. The analysis showed that disablism was present and powerful in the participants’ lives, and also showed how disablism shaped how the participants thought and felt about themselves. As Carol Thomas argues, when analysing disablism one should also focus on who we are and are prevented from being, as disabled people. The conclusion is that processes of oppression were central when it comes to understanding the (re)construction of identities. A disability studies perspective is thus relevant in the field of mental distress, and can be used to enhance the understanding of the process of identity (re)construction.     

Does Formal Education for Older Workers Increase Earnings? — Evidence Based on Rich Data and Long‐term Follow‐up

Governments in Europe, Canada and the USA have expressed an ambition to stimulate education of older. In this paper, we analyse if there are effects on annual earnings of formal education for participants aged 42–55 at the time of enrolment in 1994–95. The analysis explores longitudinal population register data stretching from 1982 to 2007. The method used is difference‐in‐differences propensity score matching based on a rich set of covariates, including indicators of health and labor market marginalization. Our findings underline the importance of long follow up periods and imply positive effects for women, especially so for women with children, and no significant average earnings effects for men. These results differ from earlier studies but are stable to several alternative assumptions regarding unobservable characteristics. Data further indicate that the gender gap in our estimates may stem from differences in underlying reasons for enrolment.     

Asymptotic Inference on Cointegrating Rank in Partial Systems

The likelihood ratio test for cointegrating rank is analyzed for partial (or conditional) systems in the vector autoregressive error-correction model. Under the assumption of weak exogeneity for the cointegrating parameters, the asymptotic distributions are given and tables of critical values are provided. A discussion is given of some of the assumptions of the model, why they are needed, and how they are tested.     

The Prevalence of Destructive Leadership Behaviour

This study investigates the prevalence of the four types of destructive leadership behaviour in the destructive and constructive leadership behaviour model, in a representative sample of the Norwegian workforce. The study employs two estimation methods: the operational classification method (OCM) and latent class cluster (LCC) analysis. The total prevalence of destructive leadership behaviour varied from 33.5% (OCM) to 61% (LCC), indicating that destructive leadership is not an anomaly. Destructive leadership comes in many shapes and forms, with passive forms prevailing over more active ones. The results showed that laissez‐faire leadership behaviour was the most prevalent destructive leadership behaviour, followed by supportive–disloyal leadership and derailed leadership, while tyrannical leadership behaviour was the least prevalent destructive leadership behaviour. Furthermore, many leaders display constructive as well as destructive behaviours, indicating that leadership is not either constructive or destructive. The study contributes to a broader theoretical perspective on what must be seen as typical behaviour among leaders.     

When do Public Managers Imitate Each Other? Mimetic Decision Making in Contracting Decisions of Danish Municipalities

Using organizational new institutional theory, this paper explores a core mechanism underlying contracting decisions in public organizations. A central proposition of this branch of institutional theory is that uncertainty leads to organizational isomorphism. The present study investigates this proposition by asking: When does perceived uncertainty lead public managers to imitative behavior in contracting out decisions? Contrary to most previous studies, we apply an individual level approach and relate different types of perceived uncertainty of decision makers to mimetic decision making. We define mimetic decision making as when decision makers deliberately obtain information about other organizations in order to possibly imitate them. In a survey of Danish municipal managers facing important and complex contracting decisions, we test our hypotheses about three types of perceived uncertainty and mimetic decision making. The results show that technological uncertainty is strongly related to mimetic decision making among public managers. However, we do not find significant results for either volume uncertainty or performance uncertainty. The paper illustrates how uncertainty, through mimetic decision making, is connected to organizational isomorphism. It further highlights that future studies should pay attention to the multidimensionality of uncertainty and its consequences.
