Sequential choice processes are ubiquitous in consumer decision making. In each attribute decision, consumers are often faced with different numbers of options which they must trade off in order to make the best possible choice. Thereby, complicated high variety choices at the beginning of a choice process produce a larger trade-off conflict and, thus, initially a greater mental depletion than more simple low variety choices. We examine the strength of mental depletion in sequential choices on individuals’ perceived attractiveness of the firm’s recommended default option at a target choice. We show that consumers who are confronted with difficult high variety choices early in the decision sequence followed by low variety choices initially deplete more than consumers who encounter exactly the same attribute decisions in reverse. As a result, depleted consumers are more likely to fall prey to the recommended default or some perceptually focal options close to the default anchor at target choice succeeding a sequence of decisions.     

A game theoretical analysis of an extended manager-auditor-conflict

Horst Albach has dealt in his research very often with problems of the quality of balance auditing (Albach 1992, 2003). Sometimes his considerations show close relations to the current crisis of the financial market and its consequences. Some of his contributions were already made in times, when it was not yet expected that the dependency of auditors from clients could once become a serious deficit of auditing. Those aspects also become relevant now in connection with the crisis of the financial market.The misgivings that arise continuously in this context with regard to the correctness of submitted balance sheets have sparked off intense discussions in two directions in the Federal Republic of Germany. Whereas the USA has already realised a prohibition of this nature to a great extent through statutory provisions, a broad spectrum of additional consultancy services is still permissible in the Federal Republic of Germany in spite of similar initiatives on the part of legislators.The present paper analyses methodically in the framework of an extended manager–auditor game how the Nash equilibrium is altered in a non-cooperative two-person game through the behaviour of the players, if the supervisory board, as an exogenous party, detects with a specific probability the incorrect certification of a substantively incorrectly prepared balance sheet. At the same time, payoffs from consultancy services for both players are included in the analysis here. However, with a greater probability of detection of an incorrectly certified incorrect balance sheet, and through the reductions of consultancy payoffs, the supervisory board can work towards the product of audit and publication quality being increased.     

Model-based measurement of latent risk in time series with applications

Summary.  Risk is at the centre of many policy decisions in companies, governments and other institutions. The risk of road fatalities concerns local governments in planning countermeasures, the risk and severity of counterparty default concerns bank risk managers daily and the risk of infection has actuarial and epidemiological consequences. However, risk cannot be observed directly and it usually varies over time. We introduce a general multivariate time series model for the analysis of risk based on latent processes for the exposure to an event, the risk of that event occurring and the severity of the event. Linear state space methods can be used for the statistical treatment of the model. The new framework is illustrated for time series of insurance claims, credit card purchases and road safety. It is shown that the general methodology can be effectively used in the assessment of risk.     

An individual-based model for competingDrosophila populations

An individual-based model forDrosophila is formulated, based on competition amongst larvae consuming the same batch of food. The predictions of the model are supported by data for single speciesDrosophila populations reared in the laboratory. The model is used to build a simple discrete model for the dynamics ofDrosophila populations that are kept over a number of generations. The dynamics of a single species is shown to give either a stable equilibrium or fluctuations which can be periodic or chaotic. When the dynamics of a species in the absence of the other is periodic or chaotic, we found coexistence or two alternative states, on neither of which the species can coexist.     

Flexible SWAps for Strategic Policy‐making: Reflections on the Zambian Experience

This article offers an alternative view on the emergence of new forms of development co‐operation by analysing the emergence of SWAps in Zambia since the early 1990s. SWAps in Zambia emerged not as part of a grand design but in response to the changing environment in which aid agencies were operating. An examination of the relative success of the health and education SWAps and the spectacular failure of the agriculture SWAp suggests that a flexible approach is more effective than the imposition of a planning template. Furthermore, the failure of the agricultural SWAp has been followed by significant new forms of public/private partnership.     

Planning for strategic flexibility

In the last 10 years much has been written about the increasing environmental uncertainty firms and other organizations have to cope with. This uncertainty made it much more difficult to plan, since unexpected events often made them obsolete.Flexibility is frequently considered as a way to ‘solve’ the problem of environmental turbulence.In this article, based upon theoretical and empirical research, the author explores the concept of flexibility, puts forward some of his research findings, and advances some implications on how to increase strategic flexibility.     

Adaptive Strategies,Gender Ideology,and Work‐Family Balance Among Dutch Dual Earners

Using questionnaire data on 149 Dutch dual‐earner couples with young children participating in the European Famwork study, we examine how adaptive strategies and gender ideology relate to parents’ perceived success in balancing work and family. Path analysis indicates that some adaptive strategies may harm individuals’ work‐family balance, particularly when they are made in the domain where the time budget is limited. In the need to succeed in multiple roles, however, endorsement of traits traditionally linked with the opposite gender, that is masculine traits for women and feminine traits for men, seems beneficial. We speculate that two underlying mechanisms — social pressure and time constraints — jointly operate in determining perceived success in balancing work and family.     

Sustainable urban development? Low-cost housing challenges in South Africa

Low-cost housing provision has been a major focus of government in post-apartheid urban South Africa. While successes can be noted, there is growing concern regarding the social and environmental sustainability of housing programs and the impacts upon both the surrounding environment and human health. Utilizing key informant interviews, survey research, Census data and documentary review, this essay identifies the major impediments to a sustainable low-cost housing provision in urban South Africa. The essay also points to hopeful signs in new policy directions, particularly attention to health issues and informal settlement upgrade programs. However, the major obstacles to a sustainable low-cost housing process, including macro-economic conditions, enduring historical legacies of race and class, the scale and rapidity of urban growth and institutional challenges show little indication of abating.     

'White Men are Liars' - another look at Aboriginal-Western interactions

Aboriginal Australia has been in the national press lately fortragic reasons. Family violence, substance abuse, unemployment,poor health, appalling living conditions, hopelessness –the statistics and stories tell a terrible tale of life in someremote area communities. Although they do not describe all Indigenouscommunities, they are a reality for a sufficiently large numberto require a radical rethink of policies designed to promoteIndigenous rights and prosperity. They exist despite structuralreforms previously achieved and believed to rectify the wrongsof the past, such as land rights, government financial support,educational
