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.     

Strategic responses to frontier-based budget allocation: Implications for bureaucratic slack

This paper analyzes the effect on bureaucratic slack of letting a sponsor apply a simple frontier-model in the budgetary process. The relationship between the sponsor and the bureaus is described within a simple game theoretic framework in which the sponsor is given the option of utilizing the frontier-technology when allocating a fixed budget to the bureaus. The effect on bureaucratic slack is shown to be ambiguous. However, conditions under which the sponsor benefits from applying the frontier-model are identified. It is also shown that collusion between bureaus does not destroy the possible benefit of applying the frontier-model.     

A Note on the Importance of Testing for Regularities for Estimated Flexible Functional Forms

In empirical productivity analysis it has become customary to use flexible functional forms to represent a firm's production technology by estimating cost functions. In this note we suggest a procedure to calculate the region where an estimated translog cost function meet the required regularities (positive cost, positive marginal cost, homogeneous, monotonicity and concavity in input prices). We calculate this region for the US Bell cost function as reported by Evans and Heckman (1984, 1986), and show that the estimated cost function had negative marginal cost in most of the test region.     

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.     

Agent-Based E-Supply Chain Decision Support

The global Internet economy is expected, over time, to give rise to increasingly agile practices where new supply chain arrangements are dynamically set up in response to changing business conditions and demands for highly customized products and services. To implement these "e-supply chain" practices, enterprises need the ability to rapidly evaluate new business opportunities and dynamically identify the best potential supply chain partners to respond to them. They also need the ability to effectively coordinate production and delivery of goods or services across the resulting value chains. In this article, we introduce MASCOT, an agent-based decision support environment for dynamic supply chain management. MASCOT agents help users distributed across multiple organizations and across different levels within a given enterprise to collaborate on the development and revision of supply chain solutions, as they evaluate different business opportunities (e.g., requests for bids from potential customers) and different sourcing options. This article also discusses new coordination protocols, developed within the context of MASCOT and aimed at better exploiting the power of finite capacity scheduling functionality across the supply chain. Empirical results are presented quantifying the benefits afforded by these new protocols under different loads and supply chain configurations.     

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.
