Über die konstruktion der ausscheidetafel der aktiven

Abstract

In der technischen Behandlung der Invaliden- oder Krankenversicherung kommt die Aufgabe vor, aus der Gruppe der Lebenden die Gruppe der Aktiven auszuscheiden. Dies wird in der Praxis vielleicht ausnahmslos derart ausgeführt, dass die Gruppe derjenigen Invaliden gleichen Alters, welche im Laufe eines Jahres invalid werden, weiter Jahr für .Jahr verfolgt wird. Angenommen, dass die Anzahl der Aktiven in einem Zeitpunkt gegeben ist, lässt sich vermittels der gegebenen Wahrscheinlichkeiten die Anzahl der während eines Jahres invalid Gewordenen und am Ende des ersten Jahres und späterer Jahre lebenden Invaliden ermitteln. Die Ausscheidetafel der Aktiven wird auf diese Weise Schritt für Schritt von dem jüngsten Alter zu den höheren weiter aufgebaut.     

A Genetic Algorithm Approach to Farm Investment

A farm portfolio model is specified with two risky enterprises and a risk-free asset which may be held short or long by the farmer. The model is solved numerically using a genetic algorithm. It is shown that the assumption of competitive adaptation leads to a violation of normative efficiency. Those who survive are not the most efficient in a normative sense.     

Global economic effects of the EU Common Agricultural Policy

Among distortions in international agricultural trade, those imposed by the European Union (EU) are the most disruptive. Under the Common Agricultural Policy (CAP), the EU has switched from being a large net importer of agricultural products to a large exporter. This has greatly altered world agricultural markets, imposing substantial costs on the EU itself and efficient agricultural exporters in the rest of the world. We show how the CAP has affected world agricultural markets and present estimates of the associated costs. First we assess the aggregate costs broken down by various product categories. Next we provide a specific example of one product, sugar.     

Consumer choice for hearing aids and listening devices: newspaper advertisements for UK private sector provision

In the UK there can be several ways to access health care and this is true of hearing aid provision. Although there may appear to be a well‐defined distinction between the National Health Service (NHS) and independent dispenser hearing aid provision, there have been many examples of overlap between the two and recent government policy initiatives mean that distinctions have become less clear. This article outlines the changing relationship between the two sectors and the problems that potential consumers face accessing information on private sector options for amplification devices. A 1‐year sample of newspaper advertisements was content‐analysed for clarity of information provided. The analysis highlighted a range of provision, from well‐known hearing aid dispensers to the greyer areas of listening device retailers and intermediary services. Some advertisements were found to have been reported to the Advertising Standards Authority. Sufficiently misleading adverts may also infringe consumer protection legislation. The article concludes there is the possibility of consumer confusion about products and their potential for amelioration.     

Limited Information and the Sustainability of Unlisted-Target Acquirers' Returns

Abstract:  Relaxed disclosure requirements of unlisted firms, as compared to publicly listed companies, lead to limited quality and quantity of information at bid announcements, causing difficulty in valuing gains from mergers. This raises the question: are the frequently reported superior announcement-period gains to unlisted-target acquirers sustainable in the long run? Our results for the UK show that unlisted-target acquirers gain on announcement, but suffer a substantial loss in the long run. This reversal in fortune of unlisted-target acquirers is in sharp contrast to the performance of listed-target acquirers in the UK. Therefore, short-run gains for unlisted-target acquirers may result from investors' excessive optimism when faced with limited and biased information.

Derivative financial instrument use in Australia

This paper examines the relation between derivatives use and financial characteristics of Australian industrial and mining firms. The firm characteristics proxy for financial distress, tax losses, managerial ownership, growth opportunities, the ability to generate operating cash flows and liquidity. We also control for firm size, dividends and exposure to foreign exchange risk. The results show that firm size and leverage are the main explanatory variables for derivative use for both industrial and mining firms     

The Allocation of Nutrient Load Reduction across a Watershed: Assessing Delivery Coefficients as an Implementation Tool

Delivery coefficients have long been used in economic analysis of policies that seek to address environmental problems like water pollution. However, the derivation and validity of delivery coefficients have not been examined carefully by empirical analyses. We derived estimates of delivery coefficients and then evaluated them as a bridge between complex simulation models and economic policies like water quality trading. We found that the allocations achieved outcomes that differed from intended water quality targets by less than 10% in most cases. For the least-cost allocation with heterogeneous costs, cost savings significantly outweighed deviations from water quality targets.
