Focusing the catastrophic illness debate.

Unlike other aspects of the American health experience, there is a current void of information on expensive illness experiences. This paper is designed to fill this void and prrsents an analysis of the incidence and cost of catastrophic illness in the United States. Catastrophic illness is defined as an illness episode for which a person incurs $5,000 or more of medical expenses in a calendar year. This information is used to provide a framework for focusing the debate about catastrophic and national health insurance.     

PROJECTION MODELS FOR U.K. FOOD AND AGRICULTURE*

Successful policy planning depends to a large extent on being able to predict the consequences of alternative measures. In the case of agriculture, it is important to know how the future pattern of supply and demand in this sector will be affected by government action on specific issues such as farm price support, and by expected trends in macro-economic variables such as national incomes and population. This paper illustrates the application of a model of U.K. agriculture to the projection of changes in the production and consumption of food and agriculture products between now and 1975. The demand projections show the effect of important levies, and of joining the E.E.C, on future expenditure on food, while the supply projections show how the output of a number of agricultural commodities will be affected by adjusting farm prices towards E.E.C. levels.     

PUBLIC DECISION GUIDES FOR WATER RESOURCE DEVELOPMENT IN WESTERN CANADA1

The concern of the paper is public river basin development in Western Canada. It attempts to set forth public decision guides and objectives in development of water resource policy. Operational formulations that are useful in public natural resource development and management are considered. Cet article traîte du développement des bassins fluviaux publiques au Canada Ouest.

A Consumer-Based Approach to Designing Product Line Extensions

A high proportion of new product introductions entail line extensions (e.g., new flavors, sizes, convenience packs, features) rather than totally new products. An attendant problem with line extending involves the possibility of cannibalization of the firm's current products. Paul Green and Abba Krieger describe an approach for designing line extensions that employs consumer tradeoff data and a variety of search heuristics to find "optimal" extensions that explicitly consider the cannibalization of current offerings. The methodology is applied to a case in which an agricultural chemicals firm is introducing a new soybean herbicide.     

Stackelberg price leadership in spatial competition

This paper examines Stackelberg price leadership in a spatially competitive model with infinitely many stores on an infinite line. A Stackelberg price leader charges significantly more than the pure Nash equilibrium price, induces its neighbors to charge somewhat more than the pure Nash equilibrium price, and increases its profits. Under Nash equilibrium, collusion of two stores makes a difference to prices only if the colluding stores are nearest neighbors. Under Stackelberg price leadership, collusion makes a difference to prices even if the stores are not nearest neighbors.     

Transaction costs and crop marketing in the communal areas of Impendle and Swayimana,KwaZulu-Natal

High transaction costs are detrimental to the efficient operation or existence of markets for inputs and outputs. The cost of information and the costs associated with the search for trade partners, the distance to formal markets and contract enforcement are likely to influence the marketing of food crops. This study hypothesises that the level of income generated from food-crop sales by small-scale farmers in the Impendle and Swayimana districts of KwaZuluNatal is influenced by transaction costs and certain household and farm characteristics. Regression analysis shows that the depth of marketing methods is significantly influenced by transaction cost proxies, such as cooperation with large commercial farmers and ownership of means of transport. Results from a block-recursive regression analysis show that the level of crop income generated is determined by the depth of marketing methods, the size of allocated arable land and off-farm income. Households with lower transaction costs, sizeable allocated land and off-farm income can be expected to generate higher income from food crops. Investment in public goods such as roads, telecommunications and an efficient legal system (to uphold commercial contracts), as well as farmer support services (input supply, extension, marketing information and research), would probably raise farm and non-farm income by reducing transaction costs. This would increase the effective demand for locally produced goods and services, thus contributing to rural employment and livelihoods within rural communal areas.     

Exchange Rate Behavior of Canada,Japan, the United Kingdom and the United States

We revisit a significant research topic on exchange rate behavior by restating the test procedures with an appropriate econometric methodology to re-examine three aspects. (i) Does the inflation (price) factor affect nominal exchange rate? (ii) Do relative interest rates affect a country’s exchange rate? (iii) Do the price and interest rate effects hold if controls for non-parity factors are embedded in tests? The quarterly data series for this study are taken over 55 years. The traditional parity condition model with price and interest rate as criterion variables is extended to take into account recently-verified non-parity factors, namely trade, productivity and foreign reserves. The results affirm that both parity factors and also the non-parity factors significantly affect the exchange rates of Canada, Japan, the United Kingdom and the United States. In our view, these findings relating to four free-floating currencies help extend our knowledge on how currency behavior is consistent with parity and non-parity theorems using a relevant methodological approach in this study.
