For any function f on the non-negative integers, we can evaluate the cumulative function o f given by o f ( s )= ~ s x=0 f ( x ) from the values of f by the recursion o f ( s )= o f ( s -1)+ f ( s ). Analogously we can use this procedure t times to evaluate the t -th order cumulative function o t f . As an alternative, in the present paper we shall derive recursions for direct evaluation of o t f when f itself satisfies a certain sort of recursion. We shall also derive recursions for the t -th order tails v t f where v f ( s )= ~ X x=s+1 f ( x ). The recursions can be applied for exact and approximate evaluation of distribution functions and stop-loss transforms of probability distributions. The class of recursions for f includes the classes discussed by Sundt (1992), incorporating the class studied by Panjer's (1981). We discuss in particular convolutions and compound functions. 相似文献

In the eyes of the beholder: the HRM capabilities of the HR function as perceived by managers and professionals

This study investigated factors influencing line managers' and professionals' perceptions of the HRM capabilities of the HR function. Using a sample of 913 managers and professionals in subsidiaries of 11 Nordic multinational corporations, we tested the extent to which features of the unit's HRM system, attitudes of the unit's general manager and characteristics of the HR manager helped explain the perceived HRM capabilities. The analysis revealed that perceived HRM practice visibility and HRM inducements (the link between individual performance and HRM‐related benefits) were strong predictors of individual perceptions of the HR function's HRM capabilities. The use of e‐HRM and the most senior manager's attitudes towards the unit's HRM practices were also significantly related to perceived HRM capabilities. 相似文献

The overall objective of this paper is to analyse the price development and price formation for wood fuel used by the Swedish district heating sector. According to Lönner et al., there is a significant potential for increasing the use of wood fuel in Sweden, at a fairly moderate cost. The basic question raised in this paper is then why this potential is not realized. Specifically, a methodology is proposed for testing whether the reason is that market imperfections are present. As a first step the shape of the technology in the Swedish district heating sector is estimated for the period 1989 to 1996. In the second step the estimated technology and the assumption of cost-minimizing firms are combined to calculate shadow prices, i.e. marginal valuation of wood fuel in this sector. If the average shadow price significantly deviates from the average observed price one may conclude that this market is functioning inefficiently due to imperfections. According to constructed bootstrap confidence intervals this difference is significant only for three out of eight years, implying that the quantities of wood fuel traded are too small. For the other years the difference is not significant, implying that one cannot, on statistical grounds, reject the efficient market hypothesis for all years. 相似文献

The article compares how low‐wage competition and labour migration from EU11 Member States affect industrial relations and working conditions for natives and migrants in three sectors (transport, cleaning and agriculture) in Denmark and Sweden. The analysis shows how already vulnerable sectors with below‐average union density and collective agreements—especially geographical dispersed sectors—are strongly affected. 相似文献
