Recently, German insurers are becoming increasingly interested in assessing and modelling risks related to new business and lapses. The final report of a DAV (German actuarial association) working party on stochastic models for German life insurance companies, released end of 2005, includes some basic approaches for this purpose. However, so far no systematic empirical research has been carried out which provides evidence for an appropriate calibration of such models. This article contributes to closing the gap. It presents the main results of an empirical analysis on the influence of policyholders’ profit participation on new business and lapses based on data about 87 German life insurance companies from 1995—2004. Analyses of regression and correlation were performed for various definitions of the explanatory variable ?profit participation“ (more precisely: the spread to some average value) and with diverse reference parameters for new business and lapses, also considering different types of life insurance. Ultimately, the exploration scarcely yielded evidence for a significant general correlation between policyholders’ profit participation and new business or lapses. However, because of the individuality of life insurance business such an evaluation of historical data can certainly only be regarded as a building block for the overall picture, as is also explained in the paper in some more detail.  相似文献

MONEY 2000? is a successful consumer education programme that was implemented by Cooperative Extension personnel in over two dozen states of the USA between 1996 and 2002. One of the unique features of this programme is that it was based on the Transtheoretical Model of Change (TTM), a framework that has been widely used to study health‐related behaviour changes such as smoking cessation. This paper first describes how the MONEY 2000? programme was developed around major constructs contained within the TTM. Findings are reported from a survey conducted with participants in the first two states that delivered the programme. The findings suggest that several change processes used by MONEY 2000? participants are associated with specific stages of change. In addition, there may be differences in behavioural changes between participants who increased their savings and those who reduced their debts.  相似文献

This paper investigates how a development moratorium affects choices of development timing and land values in a framework where both the value of developed property evolves stochastically and the development costs are fully irreversible. We assume that a regulator initially announces that land is not allowed to be developed during a finite period of time in the future. A developer, thus, must decide whether to develop land before the timing ordinance is imposed, or after it expires. The development moratorium reduces the developer’s option value from waiting and, thus, accelerates development. We also use simulation analysis to demonstrate how the other factors that relate to the demand and supply conditions of the real estate market affect this accelerating effect.  相似文献

Through the development and extension of theories and scholars’ subsequent empirical analyses of significant, theoretically grounded research questions, the knowledge about corporate entrepreneurship (CE) and its successful use continues to advance. Moreover, the literature suggests important relationships between the corporate environment, managers’ entrepreneurial behavior and successful implementation of corporate entrepreneurship actions. In an attempt to test some of those relationships, we describe an empirical study of 523 managers that examines the relationships among the antecedents to managers’ entrepreneurial behavior, a decision to implement entrepreneurial actions, and resulting job satisfaction and reinforcement practices.  相似文献
