Dynamic Adjustment In The U.S. Dairy Industry, Wayne H. Howard, Richard C. Shumway Nov 1988

Dynamic Adjustment In The U.S. Dairy Industry, Wayne H. Howard, Richard C. Shumway

Agribusiness

A dual model is used to examine the dynamic structure of the U.S. dairy industry. Properties implied by the theory of the competitive firm and independent adjustment of two quasi-fixed inputs, labor and herd size, are tested and not rejected. Instantaneous adjustment, however, is soundly rejected for each quasi-fixed input. Input adjustment to optimal levels is estimated to take about two years for labor and ten for cows. Quality adjustments of the labor and cow series do not fully embody the technological change that has occurred in this industry over the study period.


Information And Herd Health Management Practices In Texas Dairies, Wayne H. Howard, Thomas O. Knight, Richard C. Shumway, Robert W. Blake, Michael A. Tomaszewski Dec 1987

Information And Herd Health Management Practices In Texas Dairies, Wayne H. Howard, Thomas O. Knight, Richard C. Shumway, Robert W. Blake, Michael A. Tomaszewski

Agribusiness

The dissemination of information by extension agents on dairy management practices used to control mastitis and the reception and use of that information by producers are investigated. Producers are surveyed to determine current practices used. The relationship between milk yield, somatic cell count, management practices, and producer and production characteristics is estimated. Subjective probabilities are elicited from "expert," extension agents, and producers concerning the impact and cost of various management practices. Subjective marginal value products and marginal input costs are computed and compared for the respondent groups. Stochastic dominance is used to rank the relative importance of the practices as …


Projecting Regional Market Shares For Selected Florida Fresh Market Vegetables, Wayne H. Howard, Arden W. Colette Jan 1981

Projecting Regional Market Shares For Selected Florida Fresh Market Vegetables, Wayne H. Howard, Arden W. Colette

Agribusiness

Growers of tomatoes, cucumbers, eggplants and green peppers in Florida have exhibited concern about their market share in the U.S. winter fresh vegetable market. Several studies have looked at the affects of changes in tariffs and Market Orders on Florida's market share from 1962-1979 using regression and time-series analysis. Florida produce dominates the market in the eastern regions during the winter and spring season. Even though the market shares fluctuate, Florida has historically had a smaller share. The market shares have stabilized after the shocks. Forecast market shares, based on the time-series models, show Florida's producers maintaining their dominance in …


Optimal Regional Conjunctive Water Management, Jay E. Noel, Delworth B. Gardner, Charles V. Moore Aug 1980

Optimal Regional Conjunctive Water Management, Jay E. Noel, Delworth B. Gardner, Charles V. Moore

Agribusiness

An optimal control model is used to determine the socially optimal spatial and temporal allocation of groundwater and surface water among agricultural and urban uses. The control model is described briefly and its advantages over other dynamic models are enumerated. Optimal rates of groundwater pumpage over the planning horizon were highly sensitive to increasing energy costs. Groundwater basins are shown to react differently to alternative economic and hydrological parameters. In a dynamic setting, a policy of pump taxes was shown empirically to be superior to pro-rata quotas and uncontrolled pumpage.
