ECONOMIC IMPACT OF INTRODUCING ROTATIONS ON LONG ISLAND POTATO FARMS

Potatoes have been grown continuously on many Long Island (New York) fields. Environmental concerns have raised questions about the continued usage of this practice. A farm-level linear programming model was used to investigate the economic impacts of crop rotations which result in reduced potato acreage. Crop rotations (an Integrated Pest Management tactic) reduced total pesticide use, but also reduced returns above variable costs as successively stringent rotation requirements were forced into the solution. The crop rotations which caused the least effect on income were identified.Resource /Energy Economics and Policy,

The Impact of Outsourcing on Efficiency in Rural and Nonrural School Districts: The Case of Pupil Transportation in Minnesota

Government finance reforms in the United States have encouraged public entities to focus on their core mission and to use outsourcing to improve efficiency, yet little is known about whether these reforms impact rural areas differently than nonrural areas. This paper analyzes the provision of one service that is provided either in-house by school districts or outsourced— pupil transportation—and presents a variable cost function for pupil transportation for individual districts in the state of Minnesota. In-house provision of transportation was not shown to be more costly than outsourcing in either rural or nonrural locations; however, small rural districts were much more likely to provide pupil transportation in-house than other types of districts. Large contractors may seek the most profitable contracts in urban and suburban areas, while showing little interest in contracting opportunities in rural school districts

PUPIL TRANSPORTATION: THE IMPACT OF MARKET STRUCTURE ON EFFICIENCY IN RURAL, SUBURBAN, AND URBAN SCHOOL DISTRICTS IN MINNESOTA

This paper presents a cost function for the pupil transportation industry in Minnesota. In-house provision of transportation was not shown to be more costly than outsourcing. Large contractors may seek the most profitable contracts in urban and suburban areas, while showing little interest in contracting opportunities in rural school districts

Economic and Energy Savings from Cogeneration: The Case of Surface-Heated Greenhouses

Heating greenhouses by applying waste heated power plant cooling water to the outside surface could yield natural gas savings of up to 640 million therms and net present value (1980) savings of up to $2.8 billion for the continental U.S

What Have We Learned About Student Characteristics, Accommodations, and AA-MAS?

The National Center on Educational Outcomes (NCEO) and a consortium of five states joined together to form the Multi-state GSEG Toward a Defensible Alternate Assessment Based on Modified Achievement Standards (AA-MAS). This paper reports the results of one study conducted by this GSEG project. The purpose of this study was to learn more about the extent to which low performing students used accommodations. A longitudinal data set from one state was used for this analysis. The results indicated that students who performed at the 10 th percentile or above on the statewide test typically used fewer accommodations than lower performing students. And, regardless of performance level, that students instructed in less inclusive settings typically used more accommodations than other students
