Presentation and Derivation of a Five-Parameter Survival Function Intended to Model Mortality in Modern Female Populations

A single analytical expression for the probability of survival from birth to age x that would hold good for all ages in the entire human life span has been sought for centuries. With an eight-parameter function, Heligman and Pollard achieved this goal, for integer values of x , in 1980. The present paper introduces a five-parameter survival function intended to model human mortality in modern female populations. The introduced function is not only defined for integers. It is defined for all ages.     

Growth Potential for Maritime Trade and Ports in Europe

Global economic development in recent decades has been characterised by a rapidly progressing intensification in world trade and the international division of labour. As a result of the expansive development of international merchandise trade, cargo shipping has been one of the fastest growing economic sectors. The progressive global integration processes, the future reduction in trade barriers and the expected increase in prosperity in numerous regions of the world will also call for a marked expansion in world trade and cargo shipping. This designates maritime logistics as an economic sector with favourable perspectives for development. What growth rates can be expected for EU maritime trade? And what impact will these have on Europe’s ports? This article is based on the HWWI and Berenberg Bank study “Maritime Trade and Transport Logistics” published in 2007.     

CES Production Functions and Economic Growth

We examine inconsistencies and controversies related to the use of CES production functions in growth models. First, we show that not all variants of CES functions commonly used are consistently specified. Second, using a simple growth model, we find that a higher elasticity of substitution leads to a higher steady state and makes the emergence of permanent growth more probable. It is also pointed out that the effect of a higher elasticity of substitution on the speed of convergence depends on the relative scarcity of the factors of production. Finally, we discuss possible explanations of variations in the elasticity of substitution.

The influence of extrinsic product attributes on consumers’ food decisions: review and network analysis of the marketing literature

ABSTRACT

The paper synthesises the existing research on the influence of key product characteristics on the consumers’ food decision-making. By applying network analysis on a sample of 233 empirical studies from the last three decades, the paper demonstrates how marketing-specific variables are embedded in a network of other predictors. The paper also analyses network structure and density using well established measures. The results show that there is still a lack of research concerning the interplay between marketing-relevant extrinsic product attributes (e.g. price, brand, labelling, country of origin) and intrinsic food attributes, policy-related factors, as well as aspects of the proximal and distal environment. The paper identifies gaps in the marketing literature and derives research propositions. Additionally, implications for marketing practice are developed.     

The Influence of Retail Management’s Use of Social Power on Corporate Ethical Values,Employee Commitment,and Performance

Recent cases in retailing reflect that ethics have a major impact on brands and performance, in turn, demonstrating that brand owners, employees, and consumers focus on ethical values. In this study, we analyze how various sources of social power affect corporate ethical values, retailer’s commitment to the retail organization, and ultimately sales and service quality. Multi-source data based on a sample of 225 retailers indicated a strong link between power, ethics, and commitment and that these affected output performance.     

Financial innovation and the long-run demand for money in the United Kingdom and in West-Germany

Financial Innovation and the Long-Run Demand for Money in the United Kingdom and in West Germany. — This paper uses a cointegration model to compare the long-run demand for broad money in the UK and (West) Germany during the period 1963Q1–1990Q2. In the long-run demand function for Germany, real M3 is determined in classical manner by real income and a single opportunity cost variable. By contrast, the UK demand function requires in addition an explicit own rate on money as well as a risk variable. The income elasticity is also very high. These differences reflect the more rapid pace of financial innovation in the UK in the 1970s and 1980s.     

The new World Trade Organization: Pacemaker for world trade?

The Gatt Uruguay Round was finally brought to a conclusion in April following long-drawn-out negotiations. What changes are contained in the new agreements? How should we rate these changes? How important will the future World Trade Organization (WTO) be?
