The system of individual prospective aging reserve enables the insured persons irrespectively of their individual risk to change their Private Health Insurance. Besides the presentation of an implementation concept it is shown that there is no inducement to miscalculate the extent of the individual prospective aging reserve on purpose. 相似文献

When it is costly for individuals to save or to borrow, unemployment insurance (UI) provides an alternative source of liquidity
that smooths consumption over time and leads individuals to spend longer unemployed searching for a suitable job. We show
in a tractable life-cycle model how the optimal unemployment replacement ratio and the fall in consumption on job loss depend
on the cost of self-insurance and the cost of borrowing. This implies that the value of UI depends on age at job loss, consumption
needs (such as the presence of children), discount rates, the return on saving, access to credit and the presence of other
social insurance programmes. Optimal replacement rates vary substantially with plausible variation in these factors (from
less than 20 percent to almost 60 percent). 相似文献

Binary response and logistic regression in recent accounting research publications: a methodological note 总被引:1,自引:0,他引:1
We review 31 articles in leading accounting journals that performed a logistic regression analysis for a binary dependent
variable. Our review shows that many of these articles have ambiguities and errors in the presentation of the logistic regression
model. We explain that incorrect presentations of the model, even in conjunction with a correct analysis, may lead to a serious
misinterpretation of research findings. Two articles are critiqued to demonstrate the reporting problems. Our note is a call
for improvement in model presentation and related statistical analysis in the accounting field. 相似文献

We analyze the effects of commercial casinos on retail property values in the Detroit urban area. Accounting for property
characteristics and proximity to the casinos, casinos are found to have a significantly positive influence on retail property
values. The effect is stronger within a 5-mile radius of the casinos, suggesting that casinos have a complementary, rather
than substitution, effect on other businesses. This provides some of the first micro-level empirical evidence to support the
“drawing power” of casinos and the impact of consumer spending on surrounding businesses. The model developed and tested in
this study can be applied to other casino jurisdictions to gain further evidence on the impact of commercial casinos. 相似文献

Dynamic financial analysis (DFA) has become an important tool in analyzing the financial situation of insurance companies. Constant development and documentation of DFA tools has occurred during the last years. However, several questions concerning the implementation of DFA systems have not been answered in the DFA literature to date. One such important issue is the consideration of management strategies in the DFA context. The aim of this paper is to study the effects of different management strategies on a non-life insurer’s risk and return profile. Therefore, we extend the results of a recent working paper by Eling / Parnitzke / Schmeiser (2007) with two variants and test these variants numerically within a DFA simulation study. 相似文献

The impacts of product market competition on the quantity and quality of voluntary disclosures 总被引:2,自引:0,他引:2
Xi Li 《Review of Accounting Studies》2010,15(3):663-711
This study examines how firms’ voluntary disclosure decisions are influenced by product market competition. Using separate
measures to capture different dimensions of competition, I show that competition from potential entrants increases disclosure
quantity while competition from existing rivals decreases disclosure quantity. I also find that competition enhances disclosure
quality mainly through reducing the optimism in profit forecasts and reducing the pessimism in investment forecasts. Moreover,
I find that the above association is less pronounced for industry leaders, consistent with industry leaders facing less competitive
pressures than industry followers. 相似文献

This paper addresses the applicability of the convex duality method for utility maximization, in the presence of random endowment. When the underlying price process is a locally bounded semimartingale, we show that the fundamental duality relation holds true, for a wide class of utility functions and unbounded random endowments. We show this duality by exploiting Rockafellar’s theorem on integral functionals, to a random utility function. 相似文献

This study examines the impacts on consumers’ willingness to pay for certain characteristics of housing in greater New Orleans before and after the flooding of Hurricane Katrina. Single-family home sales from January 2004 to August 2006 are collected and used in a hedonic price function to estimate the changes in the value of amenities, and structural, neighborhood and geographic characteristics, including the mean elevation of each property. Elevation, which buyers did not know for certain prior to the storm, but may now be inferred from water level marks in most neighborhoods, is found to have a positive relationship with selling prices. Results indicate that pre-Katrina, there was a premium of only 1.4% per foot in flood-prone areas, and was insignificant in areas not subject to flooding. This increased to 4.6% for flooded areas after Katrina. These findings are attributed to not only the perceived risk of flooding, but also to the potential of higher compliance costs associated with rebuilding under more stringent National Flood Insurance Program (NFIP) guidelines. 相似文献

The claims made principle is one possibility to define the trigger of an insurance contract. Until now, the question whether the claims made principle is valid pursuant to German law has never been reviewed. Sec. 149 of the German Act on Insurance Contracts acknowledges the claims made principle.Particularly for long tail risks, the claims made principle has substantial advantages compared to traditional policy concepts. 相似文献

This article analyzes digital brokers in the countries of the DACH region, Germany, Austria, and Switzerland, from a business model perspective. We argue that the potential to create new value for insurance customers has not yet been fully realized. Our analysis has identified two strategic action areas. The first concerns the exploitation of the wealth of customer data available. Those digital brokers who will succeed in generating new content and services using data analytics have the potential to take customer centricity and individuality to new bounds. The second centers around introducing aspects of community, such as connecting peers and enabling them to interact. The critical success factors are volume, a high degree of automation as well as leveraging the infrastructure and data to delivering new, value-adding content and services that go beyond traditional intermediation. 相似文献
