THE RETURNS TO AGRICULTURAL RESEARCH IN MAINE: THE CASE OF A SMALL NORTHEASTERN EXPERIMENT STATION

Estimates of the marginal internal rate of return to expenditures for research by the Maine Agricultural Experiment Station are presented. Estimates are performed using ridge regression under an array of specifications, including alternative functional forms, lag structures, costs of public funds, and variable specifications. The results are consistent with many previous results that imply an underinvestment in agricultural research.Research and Development/Tech Change/Emerging Technologies,

TB135: The Estimation of the Returns to Agricultural Research and Extension in Maine: 1951-1985

The purpose of this report is to determine a statistical estimate of the returns to agricultural research at the Maine Agricultural Experiment Station during the period 1950 through 1986. The approach taken here follows most of the recent literature regarding the estimation of returns to agricultural research, by estimating an econometric production function and deriving an internal rate of return on both research and extension expenditures within the state of Maine. This estimate is derived using ridge regression techniques. The approach taken here differs somewhat from much of the returns to research literature in that it focuses on a single state, while most other work in this area considers the country as a whole. In addition the estimates here take explicit account of benefits accruing from outside of the state.https://digitalcommons.library.umaine.edu/aes_techbulletin/1071/thumbnail.jp

TOWARD A MARKETING STRATEGY FOR FRESH WILD BLUEBERRIES IN THE NORTHEAST

B827: Toward a Cooperative Marketing Strategy for Fresh Wild Blueberries

Marketing wild blueberries as a fresh product has become an increasingly viable alternative for Maine wild blueberry producers. This bulletin presents the results of research that identified marketing regions with the greatest profit potential for fresh wild blueberries and whether there are packaging or promotional strategies that are likely to be more successful than others within these regions. The authors analyze retail demand for fresh wild blueberries in Maine, Boston, and New York City, as well as describe the results of a survey of wholesale buyers of fresh blueberries in Boston. The conclusions based on the analysis of demand at these two levels of the marketing chain provide some interesting evidence with which to begin to develop a fresh wild blueberry marketing strategy.https://digitalcommons.library.umaine.edu/aes_bulletin/1042/thumbnail.jp

B816: An Economic Analysis of a Maine Dairy Farm Anaerobic Digester

Anaerobic digestion is a method for decomposing organic matter, producing in the process, biogas, which is mostly methane. This process can be used to eliminate or reduce disagreeable and often environmentally harmful characteristics of wastes. During the autumn of 1984, the University of Maine began operation of an anaerobic digestion unit acquired from Agway, Inc., a large Northeastern agricultural cooperative. This system, installed at the Witter Animal Science Center, decomposes animal manures and ultimately produces electricity and hot water. A by-product of the system is a fertilizer with characteristics superior to fertilizers produced from biological wastes that have not undergone a process of anaerobic digestion. The research objectives were to (1) construct an economic-engineering model representing the waste to energy system, (2) quantify the benefits and costs of the system, (3) estimate the cash flows accruing over the lifespan of the system, (4) evaluate the model to determine the net present value of the system, and (5) evaluate alternative scenarios to determine the effect on economic feasibility.https://digitalcommons.library.umaine.edu/aes_bulletin/1051/thumbnail.jp
