Initiation of a formula for approximate valuation of premiums for disability benefits

Abstract

The premium for a deferred disability pension payable continually during maximum n years may be expressed by means of the well known fundamental symbolic letters as in recent times, the exact value (1) is often approximated ¹ This approximation formula (2), having been used for quite a length of time in Sweden and Norway, is now officially adopted in Switzerland for the new group insurance tariffs introduced in 1948. by the expression      

The curse of bureaucratisation or the blessings of professionalisation? Nurses’ engaged adoption of quality management in hybrid managerial positions

The paper concerns how new quality management in the Danish hospital sector has created new career and professionalisation opportunities for nurses. While the well-known dualism between the logics of professionalism and managerialism is challenged in the literature, not much is known about how engagement in the tighter steering of practice may converge with professional identities and meaningfulness in work. The paper applies a Bourdieusian and ethnographic approach to the examination of nurses’ enthusiastic involvement in quality management as they take up hybrid managerial positions in an acute care department. The findings demonstrate the importance of the material and symbolic value of scientific-bureaucratic knowledge in legitimizing quality management, achieving meaningfulness in practice and bolstering the professional role of nurses.     

Bayesian smooth-and-match inference for ordinary differential equations models linear in the parameters

Dynamic processes are crucial in many empirical fields, such as in oceanography, climate science, and engineering. Processes that evolve through time are often well described by systems of ordinary differential equations (ODEs). Fitting ODEs to data has long been a bottleneck because the analytical solution of general systems of ODEs is often not explicitly available. We focus on a class of inference techniques that uses smoothing to avoid direct integration. In particular, we develop a Bayesian smooth-and-match strategy that approximates the ODE solution while performing Bayesian inference on the model parameters. We incorporate in the strategy two main sources of uncertainty: the noise level of the measured observations and the model approximation error. We assess the performance of the proposed approach in an extensive simulation study and on a canonical data set of neuronal electrical activity.     

Introducing a general class of species diversification models for phylogenetic trees

Phylogenetic trees are types of networks that describe the temporal relationship between individuals, species, or other units that are subject to evolutionary diversification. Many phylogenetic trees are constructed from molecular data that is often only available for extant species, and hence they lack all or some of the branches that did not make it into the present. This feature makes inference on the diversification process challenging. For relatively simple diversification models, analytical or numerical methods to compute the likelihood exist, but these do not work for more realistic models in which the likelihood depends on properties of the missing lineages. In this article, we study a general class of species diversification models, and we provide an expectation-maximization framework in combination with a uniform sampling scheme to perform maximum likelihood estimation of the parameters of the diversification process.     

Organizational capital,production factor resources,and relative firm size in strategic equity alliances

Access to complementary resources through strategic equity alliance networks is an important activity for both smaller and larger firms. In the literature, there is an intensive debate on the impact of alliance resources for smaller firms. We submit that the effect of alliance resources on the smaller firm financial performance depends on the attributes of these resources. Specifically, we argue that the attributes of partner organizational capital are negatively related and the attributes of partner production factor resources are positively related to the smaller firm financial performance. We test our theoretical framework by applying a longitudinal analysis to a dataset of 1730 firm-year observations of strategic equity alliances in the software industry in 25 countries over an 11-year period. We find support for our hypotheses, highlighting the critical importance of resource attributes for smaller firms in strategic equity alliance networks.     

Monopsony in the Labor Market,Minimum Wages and the Time Horizon: Some Unresolved Issues

This article discusses development of optimal solutions for monopsony in the labour market for the long run (when labour and capital are both flexible). It is shown that binding minimum wages up to a certain degree pushes the monopsonists to choose a high capital intensity of production, just as high as or even higher than that chosen when there is no regulation for minimum wages. Thereby, we demonstrate the existence of re-switching effects in the tradition of Piero Sraffa. The second part of the paper recalculates and analyzes earlier results by making use of the rather general constant elasticity of substitution production function. Based on a numerical solution for optimal monopsony under different regimes (no minimum wage, minimum wages of different values, etc.), we formulate a two-period game between the government and the monopsonistic firm (‘minimum wage game’). Finally, we analyze the relationship between the elasticity of substitution on the one hand and likely levels of employment on the other hand, after introduction of minimum wages.     

Rating Expatriate Leader Effectiveness in Multisource Feedback Systems: Cultural Distance and Hierarchical Effects

A critical challenge for global firms is to implement assessment tools to develop expatriate leaders who can effectively manage role relationships across different directions (upward, laterally, downward) in cross‐national contexts. Drawing on social categorization and relational demography theories and a data set of 360‐degree ratings of expatriates from 36 countries, we use multilevel modeling to investigate relationships between cultural distance and ratings of leadership effectiveness in task and contextual performance by colleagues with different hierarchical vantage points (subordinates, supervisors, peers). Cultural distance refers to the overall degree of difference in key cultural values identified in the GLOBE study between an expatriate's and coworkers’ countries of origin. Unlike supervisors as a rating group, results show that peer and subordinate raters as a group may be more likely to have their ratings negatively influenced by cultural distance, an effect that may be exacerbated for peer ratings from countries higher in power distance and lower in humane orientation. This study contributes to the understanding of multisource feedback systems to assess expatriate leadership effectiveness by identifying likely group ratings tendencies linked to cultural distance and hierarchical perspectives. Organizations should develop strategies to mitigate possible effects of cultural distance on subordinate and peer ratings of expatriates. © 2015 Wiley Periodicals, Inc.     

Alternative approaches to the theory of the banking firm

During the past decade, the importance of a sound microeconomic foundation for aggregate economic analysis has been increasingly emphasized. In this context, a satisfactory theory of bank behaviour appears as an indispensable prerequisite for a clear understanding of the workings of the financial sector of the economy. This has led to the development of a substantial literature attempting to model and explain the behaviour of banking firms. This paper presents a survey and discussion of the various approaches which can be found in this literature. A special effort is made to present an integrated view of the real resource and financial aspect: of banking activities.     

Design and implementation of a survey of people parking at curbside meters

A practical procedure for planning and implementing a survey of the public to obtain relevant information for municipal decision-makers is illustrated with a study of motor vehicle parking at curbside meters. Principal components are: the definition of the problem; the development of a questionnaire in consultation with the politicians and their advisors; the design of a sampling plan to reflect the breadth of potential responses from the public, and the cost of obtaining interviews; the use of machine-readable forms to reduce the sources of error, and to facilitate the monitoring of interviewer performance; and the application of statistical analysis, using standard computer programs to obtain quickly and accurately the results that are most meaningful to the ultimate decision-makers. The conclusions and recommendations from the survey may be applicable to other cities.
