    This technical bulletin is a compilation of water-related publications by the faculty of the Department since 1961. Topics range from the economics of irrigation to the use of windmills and from water supply policy to water quality in feedyards and playa lakes. Most of the publications address regional issues with widespread implications, but some articles address water issues in other regions of the United States and the world. This listing illustrates the depth and breadth of the work done on water issues within the Department.Resource /Energy Economics and Policy,

    Dynamical simplices and Fra\"iss\'e theory

    Full text link
    We simplify a criterion (due to Ibarluc\'ia and the author) which characterizes dynamical simplices, that is, sets KK of probability measures on a Cantor space XX for which there exists a minimal homeomorphism of XX whose set of invariant measures coincides with KK. We then point out that this criterion is related to Fra\"iss\'e theory, and use that connection to provide a new proof of Downarowicz' theorem stating that any Choquet simplex is affinely homeomorphic to a dynamical simplex. The construction enables us to prove that there exist minimal homeomorphisms of a Cantor space which are speedup equivalent but not orbit equivalent, answering a question of D. Ash

    Price Determinants of Ranch Horses Sold at Auction in Texas

    Get PDF
    A hedonic pricing model was used to determine parameters affecting ranch horse prices at two Texas auctions. Color, sex, age-sex interaction, sale order, and consigning ranch were all found to significantly affect price. Sire analysis found that progeny performance records did not significantly affect price.auction, hedonic model, ranch horses, Demand and Price Analysis, Livestock Production/Industries, C01, Q10,

    Economic Efficiency of Short-Term Versus Long-Term Water Rights Buyouts

    Get PDF
    Because of the decline of the Ogallala Aquifer, water districts, regional water managers, and state water officers are becoming increasingly interested in conservation policies. This study evaluates both short-term and long-term water rights buyout policies. This research develops dynamic production functions for the major crops in the Texas Panhandle. The production functions are incorporated into optimal temporal allocation models that project annual producer behavior, crop choices, water use, and aquifer declines over 60 years. Results suggest that long-term buyouts may be more economically efficient than short-term buyouts.dynamic production function, nonlinear optimization, Ogallala Aquifer, water rights buyout, Agribusiness, Environmental Economics and Policy, Q30, Q32, Q38,

    TOWARDS A COMPREHENSIVE REGIONAL WATER POLICY MODEL FOR THE TEXAS HIGH PLAINS

    Get PDF
    A 19 county, 50-year dynamic economic optimization model of irrigated crop production is linked to a detailed hydrology model for purposes of improving policy estimates of economic cost and associated water saving of groundwater conservation management policies. Spatial and temporal desegregation, allows planners to target specific areas and improve the accuracy of benefit-cost policy estimates.Resource /Energy Economics and Policy,

    Environmental effects on lunar astronomical observatories

    Get PDF
    The Moon offers a stable platform with excellent seeing conditions for astronomical observations. Some troublesome aspects of the lunar environment will need to be overcome to realize the full potential of the Moon as an observatory site. Mitigation of negative effects of vacuum, thermal radiation, dust, and micrometeorite impact is feasible with careful engineering and operational planning. Shields against impact, dust, and solar radiation need to be developed. Means of restoring degraded surfaces are probably essential for optical and thermal control surfaces deployed in long-lifetime lunar facilities. Precursor missions should be planned to validate and enhance the understanding of the lunar environment (e.g., dust behavior without and with human presence) and to determine environmental effects on surfaces and components. Precursor missions should generate data useful in establishing keepout zones around observatory facilities where rocket launches and landings, mining, and vehicular traffic could be detrimental to observatory operation

    Effectiveness of Two Water Conservation Policies: An Integrated Modeling Approach

    Get PDF
    Agriculture in the Texas High Plains depends entirely on the Ogallala Aquifer. Texas enacted water conservation legislation to address declining reserves in the aquifer. We developed an integrated regional water policy model that links a hydrology model with an economic optimization model to estimate policy impacts with respect to economic cost and water conservation. Testing the effectiveness of two policies, a groundwater extraction tax and extraction quotas, we observe that neither significantly inhibits groundwater use. Although both policies conserve similar amounts of groundwater, the regional cost of the tax policy to agriculture is more than the quota policy.integrated regional water policy model, Texas High Plains, water conservation policy, hydrology model, economic optimization model, Ogallala Aquifer, tax policy, quota policy, Agribusiness, Community/Rural/Urban Development, Food Security and Poverty, Land Economics/Use, Political Economy, Q30, Q31, Q38,

    Equal or Just? Intergenerational Allocations within Family Farm Businesses

    Get PDF
    A multi-disciplinary literature review was conducted in order to integrate multiple perspectives pertaining to family farm business transfer. Factors affecting perceptions of equality in family farm transfers were identified. Preliminary survey results analyze perceptions of equality within farm families and how these perceptions affect family farm transfer planning and implementation.family farm succession, intergenerational transfer, Farm Management, Q10, Q12,

    Parental Motivation in Family Farm Intergenerational Transfers

    Get PDF
    An intergenerational transfer model incorporating both altruism and exchange is presented for family farm transfers. A simulation study is conducted to test parental motivation in intergenerational transfers of family farm businesses. Results indicated that family farm intergenerational transfers are altruistically motivated.Family Farms, Intergenerational Transfer, Family Farm Succession, Consumer/Household Economics, Farm Management, Q10, Q12,
