Enhancing Irrigation Efficiency but Increasing Water Use: The Jevons' Paradox AgEcon
Gomez, Carlos Mario; Gutierrez, Carlos.
In this paper we analyze the conditions under which increasing technical efficiency of water use in the agricultural sector might not reduce water demand and pressures on water ecosystems. Departing from this basic problem we discuss how policy measures performed to enhance water productivity in the agriculture might be transformed into effective alternatives to improve the conservation of water resources and then guarantee the successful implementation of the Water Framework Directive. A preference revelation model is presented in the third section of the paper and one empirical application to an irrigation district in southern Spain is used in the fourth section to discuss the effectiveness of water savings measures.

Texto Bàsico de Economia Agrícola: Su importancia para el Desarrollo Local Sostenible AgEcon
Zúniga-González, Carlos Alberto.
The present works is part of my doctoral dissertation for getting title of Doctor of Philosophy with major in Science and Specialization in the Economics of Agriculture and Local Development. The research hypothesis was: “If agricultural and forest activities apply agricultural economics, then it highlights the important element for sustainable local development, useful for the policy maker and decisions taker”. Therefore, the study makes emphasis in the importance for applying agricultural economics to the forest and agricultural activities. The agricultural economics basic text is an elemental document for the agricultural economics curricular component; it is a component for the agricultural and economic science careers. The academic...

Remittances, Income Distribution, and Rural Asset Accumulation AgEcon
Adams, Richard H., Jr..
This paper examines the direct, first-rounds impact of two types of remittances—internal and external remittances—on income distribution and asset accumulation in rural Pakistan. Using income decomposition techniques on a three-year panel household data set, the paper finds that internal remittances have a positive effect on equity and that external remittances have a negative effect. The study also uses an asset-accumulation model to pinpoint the effect of remittances on five types of rural assets: irrigated land owned, rainfed land owned, livestock assets, agricultural capital, and nonfarm assets. The results show that remittances do have an effect on rural asset accumulation. While external remittances have a positive and significant effect on the...

One Player Games versus Two Player Games: Comparing Agribusiness Cooperatives with Investor-Owned Business Models AgEcon
Parker, Frederick.
Cooperative business firms are prevalent in agribusiness, yet no concise generalized model exists to demonstrate how and why cooperative firms differ from, and may be selected over, the more common investor owned business firm. It is shown within a generic transaction game that cooperatives fill both producer and consumer roles as an aggregated player that is expected to maximize aggregate producer and consumer payoffs rather than maximizing either payoff separately, which contrasts with investor owned firms as essentially two player games between separate and competing producers and consumers where each player seeks to maximize their separate payoff individually. A cardinally valued game theoretic matrix is used to demonstrate the expected differences...

The MODERE Model and The Economic Analysis of Farmers’ Decisions AgEcon
Gomez Gomez, Carlos Mario; Gutierrez, Carlos.
The MODERE, the Ministry of the Environment Irrigation Decision Model, is a simulation tool which uses mathematical programming methods to reveal the implicit multiattribute objective function lying behind the observed cropping decision. The model takes different criteria such as profit maximization, risk aversion, avoidance of management complexities and so forth into account. In order to determine the feasible combination of attributes of this objective function the model considers the production possibility frontier explicitly as depending on market prices, policy incentives, availability of production factors, water irrigation facilities agronomic vocation and other constraints. Once calibrated the model becomes a powerful tool to assess the impact of...

U.S. Executives' Views on International Agribusiness Education in the United States: An IAMA Membership Survey AgEcon
Wachenheim, Cheryl J.; Lesch, William C..
Industry members of the International Agribusiness Management Association were surveyed regarding agribusiness education. Respondents agreed that an ability to communicate and work with others are the most important skills for new graduates to possess. Skills and experiences related to international business were considered less important. Most respondents indicated that they do or are willing to assist the academic community with curricular design or implementation. Viewpoints of firms more actively involved in the academic curriculum concerning student qualifications and design of an international study program differed from those of other firms that also employ new graduates, but were not so engaged.

Forget the Hoe: Managing Invasive Plant Species with Dynamic Programming" AgEcon
Verdone, Michael; Frasier, W. Marshall.
Abstract Bromus Tectorum is an invasive plant species known to reduce abundance of native perennial grasses, increase fire frequency and intensity, decrease animal performance, and alter microbial communities and ecosystem processes. Specifically, in the Intermountain West, Bromus has been associated with decreases in livestock performance. Land managers use several methods to control invasion, but no previous studies fully integrate the dynamic interaction between control methods and the biophysical behavior of Bromus invasion. This research uses dynamic programming in conjunction with a process based ecological model to solve for optimal management strategies of Bromus invasion. The model represents biological responses to different management strategies...
