An Evolutionary Edge of Knowing Less (or: On the "Curse" of Global Information) AgEcon
Stark, Oded; Behrens, Doris A..
Consider a population of farmers who live around a lake. Each farmer engages in trade with his two adjacent neighbors. The trade is governed by a prisoner’s dilemma “rule of engagement.” A farmer’s payoff is the sum of the payoffs from the two prisoner’s dilemma games played with his two neighbors. When a farmer dies, his son takes over. The son decides whether to cooperate or defect by considering the actions taken and the payoffs received by the most prosperous members of the group comprising his own father and a set of his father’s neighbors. The size of this set, which can vary, is termed the “span of information.” It is shown that a larger span of information can be detrimental to the stable coexistence of cooperation and defection, and that in...

¿Cómo enfrentar una geografía adversa?: el rol de los activos públicos y privados AgEcon
Escobal D'Angelo, Javier; Torero, Maximo.
En el Perú, país con una asombrosa diversidad ecológica, con 84 zonas climáticas y paisajes distintos, con selvas tropicales, altas cordilleras y desiertos, puede que el contexto geográfico no sea suficiente para explicar las variaciones regionales en ingresos y bienestar, pero si es muy significativo. La pregunta más importante que este trabajo trata de responder es: qué rol juegan las variables geográficas - tanto naturales como antropogénicas - al explicarse las diferencias de gasto per cápita entre las diversas regiones del Perú. Cómo han cambiado estas influencias en el tiempo, a través de qué medios han sido transmitidas, y si el acceso a los activos privados y públicos ha compensado los efectos de una geografía adversa.

IDENTIFYING APPROPRIATE GERMPLASM FOR PARTICIPATORY BREEDING: AN EXAMPLE FROM THE CENTRAL VALLEYS OF OAXACA, MEXICO AgEcon
Bellon, Mauricio R.; Smale, Melinda; Aguirre, Alfonso; Taba, Suketoshi; Aragon, Flavio; Diaz, Jaime; Castro, Humberto.
Identifying the appropriate germplasm to be improved is a key component of any participatory breeding effort because of its implications for impacts on social welfare and genetic diversity. This paper describes a method developed to select a subset of 17 populations for a participatory breeding project from a set of 152 maize landraces. The larger set of landraces was collected in order to characterize, for conservation purposes, the maize diversity present in the Central Valleys of Oaxaca, Mexico. The method combines data representing the perspectives of both men and women members of farm households and those of genetic resources specialists, including professional plant breeders, gene bank managers, and social scientists. The different perspectives...

In search of an evolutionary edge: trading with a few, more, or many AgEcon
Stark, Oded; Behrens, Doris A..
Consider a population of farmers who live around a lake. Each farmer engages in trade with his m adjacent neighbors, where m is termed the "span of interaction." Trade is governed by a prisoner’s dilemma "rule of engagement." A farmer’s payoff is the sum of the payoffs from the m prisoner’s dilemma games played with his m/2 neighbors to the left, and with his m/2 neighbors to the right. When a farmer dies, his son takes over. The son who adheres to his father’s span of interaction decides whether to cooperate or defect by considering the actions taken and the payoffs received by the most prosperous member of the group comprising his father and his father’s m trading partners. Under a conventional structure of payoffs, it is shown that a large span of...

Measuring Social Welfare: A Dog’'s Hind Leg Possibility Postulate AgEcon
Hertzler, Greg.
Our current methods of analysing policies and the distributions of wealth insure that society is on an efficient frontier. This is not the same as a social optimum. To choose the optimal point on the frontier we need a social welfare function. Following the ordinal revolution in demand theory, a large body of research concluded that social welfare functions don't exist. The intensity of people's preferences cannot be observed and hence interpersonal comparisons are essentially impossible. This paper argues that the intensity of people's preferences can be observed and could be incorporated into a social welfare function.

The Economic Potential of Second-Generation Biofuels: Implications for Social Welfare, Land Use and Greenhouse Gas Emissions in Illinois AgEcon
Chen, Xiaoguang; Khanna, Madhu; Onal, Hayri.
This paper develops a dynamic micro-economic land use model that maximizes social welfare and internalizes externality from greenhouse gas emissions to obtain the optimal land use allocation for traditional row crops and bioenergy crops (corn stover, miscanthus and switchgrass), the mix of cellulosic feedstocks and fuel and food prices. We use this carbon tax policy as a benchmark to compare the implications of existing biofuel policies on land use, social welfare and the environment for the 2007-2022 period. The model is operationalized using yields of perennial grasses obtained from a biophysical model, county level data on yields of traditional row crops and production costs for row crops and bioenergy crops in Illinois. We show that a carbon tax policy...

The Human Right to Food as a U.S. Nutrition Concern, 1976-2006 AgEcon
Messer, Ellen; Cohen, Marc J..
For 30 years, U.S. food and nutrition scientists and policymakers concerned with food and nutrition have explored the possibility of making the human right to food (HRF) the moral and legal cornerstone of U.S. domestic and international initiatives in this area. The U.S. government has consistently opposed formal right-to-food legislation, labeling it as overly burdensome and inconsistent with constitutional law. In contrast, anti-hunger advocates have favored a rights-based framework as a way to hold government accountable for improving the nutritional situation of its poorest citizens and for saving lives and preventing malnutrition in developing countries. The U.S. government has continually expanded food and nutrition assistance at home and abroad, but...
