A normative foundation for equity‐sensitive health evaluation: The role of relative comparisons of health gains

We explore in this paper the relationship between equity‐sensitive population health evaluation measures and normative concerns for relative comparisons of health gains. Such a relationship allows us to characterize focal equity‐sensitive models for the evaluation of population health. Instances are the so‐called multiplicative Quality Adjusted Life Years (QALYs) and multiplicative Healthy Years Equivalents (HYEs), as well as generalizations of the two. Our axiomatic approach assumes social preferences over distributions of individual health states experienced in a given period of time. It conveys informational simplicity, as it does not require information about individual preferences on health.     

When Preferences for a Stable Interest Rate Become Self‐Defeating

Monetary policymakers often seem to have preferences for a stable interest rate, in addition to stable inflation and output. In this paper, we investigate the implications of having an interest rate level term in the loss function when the policymaker lacks commitment technology. We show that such preferences may become self‐defeating, in the sense that they generate a less stable interest rate than in the case without preferences for interest rate stability.     

The Broadband Access Market: Competition,Uniform Pricing and Geographical Coverage

In this paper we analyze the market for broadband access. A key feature of this market is that it is considerably more expensive to connect consumers in rural locations than in urban locations. We show that while competition increases welfare compared to monopoly when prices are free to differ across locations, the opposite may be true if there is a requirement of uniform pricing across locations. Furthermore, we show that given uniform pricing, the regulator may increase consumer surplus as well as profit by requiring a higher regional coverage than the market outcome.     

Remote operation in environmentally sensitive areas: development of early warning indicators

Exploration and production of oil and gas in certain sensitive areas such as the Barents Sea and Lofoten is controversial and further expansion depends on the ability to avoid harmful spills. One way of improving the ability to avoid such spills is to use early warning indicators. The objective of the work presented in this paper is to describe and compare strengths and weaknesses of different approaches for the development of early warning indicators. The approaches that have been compared are: safety performance-based methods; risk-based methods; incident-based methods; and resilience-based methods. There are pros and cons with all methods. All methods are very favorable with respect to some characteristics and at the same time very unfavorable to some other characteristics. They are also different in terms of scope and depth of analysis. This suggests that we should be flexible with respect to the choice of methods, and preferably use more than one method. Thus, the main conclusion is that it is favorable to have the possibility to use several different methods for the establishment of early warning indicators.     

Satisfaction and image as mediators of store loyalty drivers in grocery retailing

The purpose of this article is to analyze the role of satisfaction and image as mediators of four store loyalty drivers (store location, service quality, assortment, and price) within a comprehensive cause–effect model. The analysis employs a more holistic view of the store loyalty model than is common in a retailing context. It is based on the consistent macro-oriented National Customer Satisfaction Index (NCSI) approach. This makes it an important cross-over study, both enabling a comparison of results across industries and providing a more solid base for model validation. The data source is a survey among customers of a chain-based Norwegian grocery store which is analyzed by partial least square (PLS) and covariance-based structural equation (LISREL) estimation. A change in customer's perception of store image, where image is measured as a reflective ‘overall’ latent variable, has the expected direct significant effect on loyalty. But in addition, image will also serve as an important mediator between satisfaction and loyalty, and this is a rather uncommon result in a retailing context. Another significant finding is that a customer's perception of store assortment only influences perception of image and ultimately loyalty indirectly via satisfaction, whereas price evaluation and service quality works directly both through image building and satisfaction creation. Satisfaction creation seems to be more important for store loyalty than image building.     

What are student preschool teachers learning about diet in their education in Norway?

This article is based on a qualitative study on diet education among student preschool teachers. The problem under discussion is: What does a student preschool teacher learn in his education about food, meals, and nutrition? The material used in the article comprises interviews with student preschool teachers at one university and one college in Norway. Preschool teacher education is a three years university college study with bachelor degree. The survey results show that student preschool teachers do not receive even the most element training, when it comes to food and meals, including nutrients, vitamins, and minerals, although education must prepare them for a job outside the kindergarten. Practical cooking was almost completely absent in their education, including hygiene. Most student preschool teachers did not know what fat they were to use in cooking. Food and senses, allergies, and food and culture were not discussed in their education. There was little correlation between the formal curricula in connection with food and meals and the training the preschool teacher students received in their education.     

Cattle sharing and rental contracts in an Agrarian economy: evidence from Ethiopia

Empirical evidence on the role of cattle sharing and rental contracts in agrarian economies is limited. This article is an investigation of different types of cattle sharing and rental contracts producers in rural Ethiopia adopt. It also investigates why households in rural Ethiopia rely on these contracts that are vulnerable and therefore subject to potential moral hazard problems described in earlier literature. We apply random effect probit and control function econometric methods to household panel data collected in 2005 and 2007 from two agro‐ecological zones in Ethiopia. Controlling for the endogeneity of access to livestock credit, we find that contracts are spatially fragmented and better developed where population density is high and credit and insurance markets are poorly developed. We also find that contracts help cash poor and credit constrained households to improve their herd dynamics, to get access to nonlivestock resources (land, labor and cash) and share risks that could have been difficult without the contract. We show that contracts are rational responses of residents in rural communities characterized by imperfect credit and insurance services, since households with better access to credit are less likely to rely on contracts.
