Variations in housing satisfaction and health status in four lower socio-economic housing typologies in the eThekwini Municipality in KwaZulu-Natal

A study was done in the Durban Area, South Africa amongst residents (n?=?300) of four lower socio-economic housing typologies: Reconstruction and Development Programme (RDP) houses, informal settlements (IS), traditional rural houses (TR) and inner-city apartments (IC). Respondents living in IC were most satisfied with their dwellings, those living in RDP houses and in IS were the least satisfied. People living in the IC perceived their health best, while those living in IS perceived it as worst. Major reasons for dissatisfaction with housing were pest infestation in their dwelling in the past 12 months, inadequate toilet facilities, high temperature, unclean neighbourhood, poor ventilation and dust. Pest infestation and poor ventilation were mentioned most frequently by flat dwellers whilst RDP, IS and TR households complained about inadequate toilet facilities. For many people living in low socio-economic housing, both housing and service provision remain inadequate.     

Evaluating failure in the innovation process: the micropolitics of new product development

For almost 40 years academics from a wide range of disciplinary backgrounds have sought to improve our understanding of the innovation process. In this paper, we examine the contribution made by those such as Kotler who have attempted to describe a rational approach to New Product Development (NPD). We argue that such frameworks offer a view of organisational activity which substantially understates the political activity associated with managing the innovation process. Most of those writing from a marketing perspective acknowledge external political influences such as government policies and the leverage of 'special interest groups'. We focus on the work of Burns and Stalker who clearly recognised the way in which internal political struggles to access resources or to improve career prospects impact on innovation. To analyse the role of micropolitics in the NPD process we describe the case of WEL, a medium-sized manufacturing firm, as managers and engineers attempted to develop an important new product. We conclude that it is essential to incorporate the role of internal politics into any framework which claims to offer a realistic account of NPD.     

Risk premiums and predictive ability of BAX futures

This study provides an in‐depth analysis of risk premiums in the Canadian Bankers' Acceptances futures (BAX) market. The predictive regressions for excess and holding‐period returns on BAX futures lend empirical support to the presence of time‐varying risk premiums especially at longer horizons. Despite the evidence of time variation in the risk premium, however, the unbiasedness of the basis as a predictor of spot returns in forecast efficiency regressions cannot be rejected. The out‐of‐sample forecasts of spot returns demonstrate the excellent predictive ability of models that exploit the restrictions implied by the unbiasedness hypothesis. Overall, our findings support the presence of a slowly moving risk premium and entail important practical implications for measuring monetary policy expectations and portfolio allocation. © 2010 Wiley Periodicals, Inc.

A Solution Methodology for Probabilistic Capital Budgeting Problems Using Complex Utility Functions

Historically, the study of economic equipment replacement is primarily limited to that of a single machine or a single machining system. The replacement situation whereby machines under consideration are part of a large integrated system has received little attention. This paper proposes a framework, for the analysis of multiple-machine replacement within an integrated system context. The major difficulty of analyzing such a problem lies in the interactive nature of an integrated system; that is, how should the effects to the entire system be assessed as a result of alterations to one or more of its components. The emphasis of this work is on the issues regarding multiple machine replacement. A single-period model is utilized in order to simplify the presentation. A comprehensive example is also provided for illustration.     

An Exploratory Study of the Impact of Degree of Religiousness Upon an Individual's Corporate Social Responsiveness Orientation

The recent failures and scandals involving many large businesses have highlighted the importance of corporate social responsibility as a fundamental factor in the soundness of the free market system. The corporate social responsiveness orientation of business executives plays an important role in corporate decision making since managers make important decisions on behalf of their corporations. This paper explores whether there is a relationship between an individual's degree of religiousness and his or her corporate social responsiveness (CSR) orientation. The results of a survey of 473 business students found a significant relationship between degree of religiousness and attitudes toward the economic and ethical components of CSR. Some explanations as well as limited generalizations and implications are developed.     

Practical Implications of Educational Background on Future Corporate Exceutives' Social Responsibility Orientation

Differences between business students atsecular and non-secular universities withregard to their corporate social responsibilityorientation (CSRO) are examined. The resultsshow that the two groups' attitudes toward thefour components of CSRO are significantlydifferent. Specifically, compared to businessstudents in non-secular institutions, thestudents of secular universities exhibitgreater concern about the legal component ofcorporate responsibility and a weakerorientation toward discretionary activities. Nosignificant differences between the two groupswere observed with respect to economicperformance and the ethical dimension.Explanations as well as limited generalizationsand implications are developed.     

Longevity Risk

Most of the western world has seen a steady increase in the average lifetime of its inhabitants over the past century. Although the past trends suggest that further changes in mortality rates are to be expected, considerable uncertainty exists regarding the future development of mortality. This type of uncertainty is referred to as longevity risk. This paper reviews the current state of the literature concerning longevity risk. First, we discuss the modeling of future mortality, including the Lee and Carter (J Am Stat Assoc 87:659–671, 1992)-approach, as well as other approaches. Second we discuss the importance of longevity risk for the solvency of portfolios of pension and life insurance products. Finally, we investigate possibilities for longevity risk management. In particular, we consider longevity risk management through securitization and/or pension and insurance (re)design.     

Currency crisis transmission through international trade

The Eurozone recent crisis has shown how balance of payments problems in less developed European Monetary Union (EMU) member countries can affect EMU trading partners, spreading the crisis to a larger group of countries. This paper introduces a three-country dynamic general equilibrium model to analyze whether and how terms of trade effects can generate a spillover effect or a currency crisis transmission between countries. Specifically, using a two period model, it incorporates world market clearing conditions for tradables into a new theoretic model, analyzes net capital flow movements between countries, and establishes cross-border macroeconomic linkages. This paper shows how a currency crisis can transmit through the real (trade) sector channel of the economy.     

Hiring Risky Workers: Some Evidence

Lazear recently suggested that firms that do not expect to live for a long time will hire only safe workers. Hence their worker turnover will be lower. In this paper we test this hypothesis using both the industry growth rate and industry-average age of establishments as measures of the horizon for a particular firm. We find mixed results, both at the industry level and at the establishment level. Establishments in growing industries do indeed exhibit higher churning flows, but a high average age of establishments reduces rather than increases churning.
