This paper presents an integrated model for the economic and environmental assessment of the use of natural resources when new activities (i.e. biomass crops for energy production) are introduced into the farm production plan. The methodology is based on the integration of positive mathematical...

Irrigation water demand is estimated using field-level panel data from Kansas over 16 years. The cost of pumping varies over time due to changes in energy prices and across space due to differences in the depth to water. Exploiting this variation allows us to estimate the demand elasticity while...

In this paper we analyse the economic impact of alternative water management instruments that allow addressing the problem of non-renewable groundwater pumping in the aquifers of the Guadalentín Valley (southeast Spain). Their impact is assessed using a partial equilibrium mathematical...

This paper determines the demand for a forestry program amongst rural households in western Kenya. It is based on a field survey with 277 households, using a stratified random sampling approach. The study follows attribute based method to elicit farmers’ preferences. Demand is measured in...

This paper analyses the economics of biofuel production and the implications that the accelerating growth in biofuel production in many countries could have on agricultural markets. It shows that production costs of ethanol and biodiesel differ significantly across countries and feedstock crops....

This study examines the dynamic effects of grain prices and energy prices on catfish feed prices and the price of food-sized catfish at the farm level. Using the autoregressive distributed lag model and bounds testing procedure, a long-run relationship between feed and farm prices and their...

Recent increases in the price of crude oil have led to a rise in the prominence of corn-based ethanol as an alternative source of energy. As a result linkages have been established between commodity and energy prices. The aim of this study is to determine if soybeans, corn, wheat, oil, and...

This paper considers the effects of granting a fishermen's sales organization exclusive rights to sell unprocessed fish. On the assumption that the fishermen's monopolyis able to discriminate between plants and end use alternatives in its pricing policy, the conditions for profit maximization...

Production costs for fresh Atlantic groundfish and scallop processing are examined using direct observation, linear regression analysis, and cost accounting. Assuming that management chooses a production technique where marginal costs are constant over a wide range of production due to...

To value water quality improvements in the Chesapeake Bay or elsewhere, it is necessary to choose an appropriate model of consumer behavior. A number of different travel cost based recreation demand models have beenemployed to value changes in water quality or beach access. Among the possible...
