Abstract: In the paper, we use the theory of mechanism design to exhibit the cost of efficient provision of healthcare, defined as the uniquely defined sum of individual side payments which would eliminate moral hazard. It is argued that this cost may be used to assess the costs arising from use of the treatment in cases where it is not appropriate from a strictly medical point of view. An example is given to indicate how this assessment might enter into practical cost-effectiveness analysis. URI: http://hdl.handle.net/10398/7626 Files in this item: 1

A model of trade with several countries where local integration benefits allHansen, Bodil O.; Keiding, Hans (København, 2005)[More information][Less information]
Abstract: For the study of economic integration, it is costumary to use a three countryworld, where two of the countries may introduce forms of closer economic cooperation. In the present model, we follow this tradition but put special emphasis on the role of credit and entrepreneurship. Our model is of the standard neoclassical type, with the addition that production takes time and is subject to uncertainty. Also, firms must use the financial system in order to buy inputs; the cost of credit may differ among countries and industries, reflecting their basic patterns of uncertainty. Following the Newbery-Stiglitz approach, we show that in such model we may exhibit cases of Pareto inferior trade and, in particular, Pareto inferior economic integration. More specifically, we show that integrating countries of very different economic size may give rise to adverse effects on welfare, whereas integration of countries with a more similar economic structure and size tends to have beneficial effects for the parties. Keywords: trade, uncertainty, Pareto inferior trade, regional integration. JEL classification: F11, F15, F34 URI: http://hdl.handle.net/10398/7495 Files in this item: 1

Abstract: We consider a model of commercial television market, where private broadcasters coexist with a public television broadcaster. Assuming that the public TV station follows a policy of Ramsey pricing whereas the private stations are profit maximizers, we consider the equilibria in this market and compare with a situation where the public station is privatized and acts as another private TV broadcaster. A closer scrutiny of the market for commercial television leads to a distinction between target rating points, which are the prime unit of account in TV advertising, and net coverage, which is the final goal of advertisers. Working with net coverage as the fundamental concept, we exploit the models of competition between public and private price and quantity in order to show that privatization of the public TV station entails a welfare loss and results in TV advertising becoming more expensive. Keywords: TV broadcasting, imperfect competition, Ramsey pricing, welfare comparison. JEL classification: L11, L82, L33 URI: http://hdl.handle.net/10398/7501 Files in this item: 1
