NATIONAL PRODUCT AT CONSTANT PRICES IN THE FEDERAL REPUBLIC OF GERMANY

With few exceptions, only cormmodity flows and values which can be determined by means of commodity flows (flows of goods and services) are calculated in constant prices in the official national accounts of the Federal Republic of Germany. Figures an the industrial origin and the final use of the national product are published, the former according to thirty industries, the latter according to the major types of uses of which in particular private consumption expenditure has been further analysed. The computations at constant prices are based on market prices and not on factor costs. It is only on this basis that a uniform valuation of the production and the expenditure side can be made since the turnover tax, which is the most important indirect tax, is contained in the elements of final demand in varying shares and cannot be eliminated (the tax is part of the price and has cumulative effect). The computation at constant prices presupposes a breakdown of the values in current prices according to quantities and prices. This raises a number of problems, e.g. because seller and buyer may consider differing aspects-production costs, technical attributes, etc., on the one hand, and use etc., on the other hand. In part there exist only vague ideas, or no ideas at all, as to what is to be considered-from a theoretical point of view-as quantity and price. In other cases the two values can only with great difficulties, if at all, be quantified, or there exists no market price and only the production costs are available. The author deals in greater detail with differences in quality and new commodities, the determination and treatment of quantities and prices for services, in particular for trade services (services attached to goods), the computation of government services at constant prices considering the development of productivity in public service, the determination of the values calculated as balances, above all the treatment of changes in the terms of trade for net exports of goods and services, the computation of the contributions of industries to the gross domestic product and, finally, the reconciliation of the production and the expenditure side. In a third section the author deals with index formulae and the base year. In the majority of cases values are deflated; partly, however, they are currently adjusted by means of volume and quantity data. On the production side the two methods are in part combined. In a concluding section a survey is provided of the computation methods used in the Federal Republic of Germany and on the available material for the computations. Mention is made of depreciation at constant prices.     

The Effect of Sample Size on the Mean Efficiency in DEA with an Application to Electricity Distribution in Australia,Sweden and New Zealand

This study examines the effect of sample size on the mean productive efficiency of firms when the efficiency is evaluated using the non-parametric approach of Data Envelopment Analysis. By employing Monte Carlo simulation, we show how the mean efficiency is related to the sample size. The paper discusses the implications for international comparisons. As an application, we investigate the efficiency of the electricity distribution industries in Australia, Sweden and New Zealand.

Interaction effects between dynamic hybrid products and traditional deferred annuities in the German life insurance market

Financial Markets and Portfolio Management - Dynamic hybrid products emerged in 2007 and are now well established in the German life insurance market. In this article, we study interaction effects...     

The dynamics of premium reserves of life annuities under the regime of Solvency II

The article considers the solvency requirements for a whole portfolio of annuities under the regime of Solvency II. More precisely, the following question is investigated: Which demand of interest on the initial capital – the Solvency II premium reserves – is needed in order to fit the balance for Solvency II capital requirements in the next year? It turns out, that even for a model portfolio of simple annuities with say guaranteed interest rate of 1,25% the demand of interest in one year is greater than 3%. So even if a life insurance company fulfill the capital requirements of Solvency II in 2016 the mentioned effect causes eventually problems in future times.     

Consuming apart,together: the role of multiple identities in sustainable behaviour

Although consumers’ awareness of the environmental and ethical consequences of their behaviour has grown, research on the role of multiple consumer identities in sustainability behaviours is scarce. The aim of the current study was to explain sustainable behaviour from a social identity perspective. We conducted a longitudinal cross‐national within‐subjects design consumer study in six countries (T1, N=3083; T2, N=1440). The results indicate that environmental sustainability can comprise several distinct yet overlapping sustainable behaviours. Multiple social identities seem to play different roles in these different behaviours. Therefore, efforts to enhance different sustainability behaviours are challenging yet promising. Once consumers incorporate a sustainable behaviour, it becomes part of their own identity and could lead to spill over effects on other closely related sustainable behaviours.     

Children's Opportunities in Germany – An Application Using Multidimensional Measures

Single parents and unmarried couples are increasingly replacing the traditional nuclear family. This paper investigates if the greater variety in living arrangements contributes to increased resource disparities among children in Germany. Children in single parent families are disadvantaged in at least three dimensions decisive for their later achievements: material standard of living, parental education, and parental childcare time. We compute multidimensional inequality and poverty indices using SOEP data from 1991 to 2012. We distinguish between parental and publicly provided childcare, which is an increasingly important in‐kind benefit in Germany. We find that both multidimensional inequality and poverty declined as expanded public childcare strongly reduces resource disparities among children.     

Foreign Direct Investment in Sub-Saharan Africa: Motivating Factors and Policy Issues

Sub-Saharan Africa's (SSA) foreign direct investment (FDI) share has persistently averaged 1% of global flows. The location decision and perceptions of investors are therefore instructive for policy making. This article factor analyses a survey of perceptions, operations, and motivations of 758 foreign investors in 10 SSA countries. We find that the provision of transaction cost–reducing information on industries and markets and utility services to investors before and after a firm's FDI decision are significant factors. FDI location decision in SSA is influenced strongly by political economy considerations. Labor and production input variables are not influential.
