| This paper examines the impacts of alternative management strategies for the production of alfalfa within the context of a total farm plan. A linear programming model is used to represent a 600-acre farm which can grow either grain crops or alfalfa. Alfalfa production competes with the grain crops for available land, labor, machinery, and field time over a calendar of tillage, plating, cutting, spraying, and harvesting activities. The profitability of an acre of alfalfa and the contribution of alfalfa to net returns for the farm varies quite widely depending on the particular alfalfa management strategy selected. |

| A growing share of water pollution in the U.S. can be attributed to nonpoint sources (USEPA 2002). Some of this trend can be attributed to declining point source (PS) emissions as a result of regulation under the Clean Water Act (CWA). However, fertilizer-intensive practices used to improve agricultural productivity over recent decades have also increased nitrate loads and resulted in water quality impairments. Nonpoint source (NPS) pollution from agricultural practices is generally exempt from federal regulation. However, some voluntary programs allow point sources subject to the CWA’s effluent limitations to meet their standards by purchasing offset credits reflecting reductions in NPS discharges to the same waters (USEPA 2004). Such water quality... |

| This study examines the effects of price incentives on the availability of petroleum. Expected sustained higher crude oil prices to domestic producers constitute an incentive to increase both exploratory drilling and secondary and tertiary recovery of oil as well as production out of reserves. Reserve-production ratios tend to fall under high prices. Equalization of the domestic price to the real world price would make the U.S. self sufficient within a six year period. Constant prices result in no new additions to reserves after a five year period and very low production levels. Imports reach sixty-five percent of domestic consumption. |

| A conjoint analysis of equestrian trail characteristics (trail length, scenic views, open land, bathroom/shower facilities, restricted use, distance, and entrance fee) is conducted for the state of Kentucky. The conditional logit results show location is an important determiner of willingness to pay. In particular, scenic views and restricted use are highly valued (WTP above $20). However, increased distance from home to the trail results in a negative willingness to pay. |

| This study developed an intertemporal profit function to determine optimal conservation adoption strategies under alternative scenarios with respect to crop prices, relative yields, discount rates, and other assumptions. Special emphasis was placed on determining from the analysis when the switchover from conventional to soil-conserving practices should take place. Technological change was incorporated by allowing crop yields to vary over time. Our analysis thus provides a new, more precise measurement of the cumulative net benefit differential. The optimal period for switchover from conventional to soil-conservating practices was found to vary depending on the assumptions made about corn prices and discount rates. Empirical results were based on an... |

| Using data collected from a combination of on-site and on-line surveys, this study examines recreational demand for equestrian trail-riding in Kentucky. A truncated, negative binomial regression is applied to analyze individuals’ visitation behavior consistent with a travel cost model. Results suggest that distance is the most significant determinant of average annual visits to a particular site. Various trail site characteristics, such as trail length, scenic overlooks, and trail markers, affect the number of visits an individual takes. Geographic information system (GIS) analysis permits the identification of equestrian population centers. Information obtained from this study offers a decision base for policymakers to use to manage existing equestrian... |

| An empirical analysis reveals that states with more highly educated populations have better environmental conditions, after controlling for income, population density, and industrial composition. The strategy of raising human capital stocks to maintain or improve environmental quality is proposed as a complement, if not an alternative, to direct government intervention, which consists of command and control, market incentives, and moral suasion. Under this approach, general education becomes the control variable that guides economic behavior in a manner consistent with long-term environmental sustainability. |
