Customer segmentation in retailing based on retail brand patronage patterns

In this study, we propose an alternative method for customer segmentation based on households’ retail brand portfolios. We suggest blockmodeling, a method that is rooted in social network analysis, to identify homogeneous groups of customers being characterized by similar patronage patterns. In a second step, we combine this method with psychometric analyses to examine group differences based on sociodemographic and purchasing behavior variables. To illustrate our approach, we use a sample of 500 households out of a panel data set of 36,502 German households in the fast-moving consumer goods sector. The findings of our analyses yield support for our assumption that our methodology, taking into account the relationship between households and the different retail brands they patronize, provides a broader understanding of the antecedents of households’ multiple store patronage strategies, leading eventually to a new form of customer segmentation.     

Measuring regional income disparities in LDCs

The problem of income disparities in developing countries is constantly gaining in importance. Clearly a pure growth strategy alone cannot be effective and disparities are steadily increasing. What is needed for an effective policy first of all are adequate statistics and indicators.     

When are bonus payments for managers perceived as fair? Results from a quasi-experiment

We investigate under which circumstances bonus payments for managers are accepted as fair, asking workers to judge several hypothetical scenarios. We find that perceptions vary widely with the characteristics of the situation, as well as with the workers’ general attitudes.     

Demand for a labor‐based drought insurance scheme in Ethiopia: a stated choice experiment approach

Index‐based weather insurance is increasingly used to manage weather‐related risks in smallholder agriculture. However, cash‐constrained smallholders often lack the resources to pay an insurance premium, which may undermine its wider adoption. This article investigates alternative insurance payment methods that may help to enhance the adoption of index‐based weather insurance. We use a choice experiment to elicit smallholders’ willingness to pay in cash or labor for index‐based weather insurance in four districts in the south‐central highlands of Ethiopia. The insurance schemes were created using a fractional factorial design with three factors: work, cash, and payout rate. We analyze the choice data using a random parameter mixed logit model. We find that the average participants need a subsidy to pay cash for insurance because their willingness to pay is less than the expected cost of the insurance. On average, they are willing to pay only 0.81 ETB (Ethiopian currency) to get an expected yearly payout of 1 ETB. However, most are willing to participate in work‐for‐insurance programs at lower daily wage rates than is common for other work programs in Ethiopia.     

A comparative analysis of rice–wheat systems in Indian Haryana and Pakistan Punjab

Intensive irrigated rice–wheat production systems have converted the north-west Indo-Gangetic Plains into South Asia's cereal basket. Their strategic importance is undermined by a slowdown in productivity growth linked to the degradation of soil and water resources. Findings from farm surveys are used to examine contrasts and similarities between rice and wheat farms, cultivation practices, productivity, and profitability in the rice–wheat belt of India's Haryana State and Pakistan's Punjab province. In Haryana average wheat and paddy yields are markedly higher, but the yield advantage is offset by higher total production costs, resulting in lower private returns. The diverging institutional environment including varying levels of intervention in produce and input markets contributed to the evolution of the Pakistani production model as relatively ‘medium input–medium output’ and the Indian production model as ‘high input–high output’. The study reiterates the need to reinvigorate productivity growth and to reduce production costs in these intensive cereal production systems while conserving natural resources such as water and limiting negative environmental impacts. The study however also raises questions about the future of current rice–wheat systems.     

Changing Food Consumption of Households in Developing Countries: A Bangladesh Case

Increasing incomes, urbanization, and population growth are transforming developing countries. This structural transformation is changing lifestyles and consequently food consumption and agri-food systems. The present study uses Bangladesh as a case study, a rapidly growing developing economy in South Asia to examine the changing food consumption pattern. Using information from more than 29,000 households, the present study demonstrates that, with the increase in income and urbanization, this traditional rice-consuming country is increasingly consuming more wheat. The changes in the relative consumption in Bangladesh are prominent both in rural and urban areas. The literature often is based on the premise that with increasing income, households switch from staple cereals to high food-value items. The present study highlights the need to also consider within-staple substitution.     

Germany's New Insider Law: The Empirical Evidence after the First Year

Abstract. This paper investigates insider trading activities in German stocks during the first year following implementation of the new Insider Law on 1 July 2002. It can be observed that insiders act as contrarian investors. They buy stocks after prices have fallen and sell stocks after prices have risen. In general, insider trades are very profitable. A typical stock purchased by an insider yields an abnormal return of almost 3 per cent during the 25 days following the transaction. In contrast, a typical stock that has been sold by insiders achieves an abnormal return of nearly −3 per cent over the same time period. Outsiders who copy the transactions of insiders can achieve nearly the same abnormal returns. Abnormal returns remain substantial even after transaction costs. The results suggest that prices of stocks in which insiders trade do not seem to be semi-strong efficient.     

Coercion,Guidance and Mercifulness: The Different Influences of Ethics Programs on Decision-Making

The development of an ethics program is a method frequently used for organising responsible behaviour within organisations. For such a program, certain preconditions have to be created in the structure, culture and strategy. In this organisational context, managers have to take their decisions in a responsible way. This process of decision-making, embedded in an ethics program, is the main focus of this article. Ethics programs often influence decision-making in a formal way; certain norms and types of behaviour are formalised and controlled within the organisation. Subsequently, individual managers have to infer the meaning of responsible behaviour from the demands laid down in the ethics program. Such a formal ethics program has some important advantages but the dangers of such an approach are often ignored. This article discusses both the advantages and disadvantages of a formal ethics program and adds two alternative ways of stimulating responsible behaviour in the organisation. In a monological approach the reflections of the decision makers on their own values are central in differentiating between right and wrong. In a dialogical approach, the communications between decision makers and other stakeholders involved are the foundations for determining a responsible solution. Because each approach is appropriate for certain issues, a well-chosen combination is justified. Such an ethics program should be strict on certain issues but leave room for reflection and interaction on other issues.     

Versicherungsfremde Leistungen in der Gesetzlichen Krankenversicherung

In der jüngeren Vergangenheit ist eine Tendenz zur verst?rkten Finanzierung der Gesetzlichen Krankenversicherung mit Haushaltsmitteln des Bundes erkennbar. Mit einem Bundeszuschuss sollen die Aufwendungen der GKV für versicherungsfremde Leistungen fi nanziert werden. Ob der Bundeszuschuss korrekt bemessen ist, kann aber nur dann festgestellt werden, wenn auch der Umfang der versicherungsfremden Leistungen in der GKV bekannt ist.
