This paper applies alternative panel data models to a cross‐sectional dataset that contains observations at the plot level for a sample of wine‐grape farms in Central Chile. The input‐output data as well as key attributes of the production system are at the plot level, at which individualized management exists. However, plots belonging to a particu...

This study aims to weigh the influence of observable traits on live cattle prices, i.e., the percent impact on the final price of various physical characteristics. These characteristics are those that commonly are published in auction catalogues, as is the case of: average lot weight, lot size, age, breed and corporal condition. In addition, the in...

Chile has become an increasingly important player in international wine markets. Concurrent with the expansion of Chilean wine output and exports, there has been an increase in production in several other "New World" countries including Argentina, Australia, New Zealand and South Africa. The overall growth in wine supplies has increased competition...

Text book in farm management. Includes economic principles and applications. Written for Spanish speaking students of farm business.

This study aims at estimating the percent impact on the price of farmland of the following physical attributes: size, soil quality, water rights, connectivity and location. To this effect, all the farm sales occurred in the province of Talca between 2003 and 2006 were examined, directly from the corresponding title deeds, at the Conservador de Bien...

A log-linear hedonic price function for Chilean avocados cv. Hass for the international market was estimated. The data were obtained directly from the export bulletins of the 2005-2006 season from a reputable Chilean fruit company located in Quillota, which is the heart of the avocado plantations in Chile. FOB price (in logs) was explained accordin...

A hedonic price function for Argentinean wines in the U.S market is estimated in order to evaluate the effect of the most important attributes of wine on price. Results show that labeling practices and the choice of the right wine quality attributes are far more influential on price than expert panel opinions or oenological wine improvements such a...

This study aims at determining the marginal prices of agronomic and marketing variables for Chilean export apples. The agronomic variables are variety and size, and the marketing variables destination port and month of sale. The database corresponds to the 2002-03 and 2003-04 seasons and was obtained directly from the export bulletins of an importa...

Se estimó una función de precios hedónicos asociando el precio al detalle del vino chileno en el mercado estadounidense a los siguientes atributos visibles: nota de calidad, envejecimiento, cepa, valle de origen y pertenencia a alguna asociación de productores. Se estimó el impacto porcentual en el precio de cada uno de estos atributos para las ven...

A hedonic function relating the retail price of Chilean wine in the US market to a number of relevant variables was estimated. The variables were: quality ratings, aging, grape variety, valley of origin and membership to an association. Estimates for the percentage impact and marginal prices of these variables are provided. The overall conclusion i...

Se estimó un modelo de oferta y demanda de vino, utilizando series de tiempo del periódo 1980 a 2004. El consumo doméstico de vino se estimó en función del propio precio, precios de sustitutos (cerveza, bebidas gaseosas), población mayor de 18 años y gasto en consumo per cápita, como proxy de ingreso. Puesto que el vino es un bien transable de expo...

An hedonic function relating the retail price of Chilean wine in the USA market to the following variables was estimated: quality rating, aging, variety, valley of origin and membership to an association. Estimates for the percentage impact of each of these factors were estimated for all vintages carried out from 1989 to 2002 and for all the vintag...

Se analiza la evolución del precio de la tierra y la rentabilidad de la agricultura en el período 1983 a 2002, y la influencia de la segunda variable en la primera. También se analiza la plusvalía de la tierra atribuible a factores distintos a rentabilidad agrícola, para el período indicado. Para estudiar la evolución del precio de la tierra se div...

Este estudio busca determinar las ventajas relativas de una cosecha mecánica de uva vinífera en comparación con la cosecha manual. Durante las vendimias de los años 1998 y 1999 se recogieron 20 muestras directamente de la tolva de una vendimiadora automotriz e igual número de muestras de las gamelas de cosechadores manuales, con el fin de analizar...

This study aims at determining the relative advantages of mechanical wine grape harvesting in comparison to handpicking. During the 1998 and 1999 harvests, 20 fruit samples were collected directly from the collectors of a self-propelled grape harvester and an equal number from the baskets of hand pickers, with the purpose of evaluating the quality...

Standard artificial breeding of the freshwater snail Physa venustula for ecotoxicological evaluation of pesticides was realized. The bioassays were standardized with a breeding protocol of four batches of P. venustula fed with a solution of Cereal Leaves™ plus fishmeal and Chlorella vulgaris in our laboratory. The oviposition had a downward trend t...

This study aimed at describing the current technological levels of the irrigated vineyard farm industry of the Central Valley of Chile, by estimating the production, cost and productivity variations associated with size and estimating the optimal plantation size. To that purpose, a survey of 82 randomly selected vineyard farms, equivalent to 4.8% o...

Se aplicó una encuesta a una muestra aleatoria de 82 empresas vitícolas de riego ubicadas entre las regiones V a VII de Chile, equivalentes al 4,8 por ciento del universo estadístico, con el objetivo de describir la tecnología que actualmente aplica este subsector agrícola, los cambios en la producción y los costos asociados al tamaño de plantación...

If activity net revenue distributions for farm planning under risk are subjectively assessed, the claimed advantages of MOT AD (Minimisation Of Total Absolute Deviation) programming can be reaped only if some way can be found of generating discrete vectors of net revenue deviations. Pseudo-random sampling is evaluated for this purpose and it is sho...

Phytophthora cinnamomi está considerada como el principal agente asociado con el decaimiento de Quercus en Andalucía. Sin embargo, frecuentemente aparecen chancros en los árboles que sufren el decaimiento en esta región. En las prospecciones llevadas a cabo en Andalucía en zonas afectadas de decaimiento, se detectó la presencia de áreas alargadas d...
