Vineyard Acreage in Oregon, 1982

This statewide survey report on vineyard acreage in Oregon covers bearing and nonbearing acres, size of vineyard operation, variety and county, size distribution, prices, and yields. The report also contains some comparisons of data for 1981 and 1982

Using a Hedonic Model of Solar Radiation to Assess the Economic Effect of Climate Change: The Case of Mosel Valley Vineyards

In this paper we provide a simple, credible method for assessing the effects of climate change on the quality of agricultural land and then apply this method using a rich set of data on the vineyards of the Mosel Valley in Germany. The basic idea is to use a simple model of solar radiation to measure the amount of energy collected by a vineyard, and then to establish the econometric relation between energy and vineyard quality. Coupling this hedonic function with the elementary physics of heat and energy permits a straightforward calculation of the impact of any climate change on vineyard quality (and prices). We show that the variability in vineyard quality in this region is due primarily to the extent to which each vineyard is able to capture radiant solar energy, so that these data provide a particularly credible “experiment” for identifying and measuring the appropriate hedonic equation. Our empirical results indicate that the vineyards of the Mosel Valley will increase in value under a scenario of global warming, and perhaps by a considerable amount. Vineyard and grape prices increase more than proportionally with greater ripeness, so that we estimate a 3°C increase in temperature would more than double the value of this vineyard area, while a 1°C increase would increase prices by about 20 percent.

CHARACTERISATION AND TECHNICAL EFFICIENCY OF PORTUGUESE WINE FARMS

This study aims to characterise the evolution of vineyard production, to measure the levels of technical efficiency, and to relate these with farmers and farms attributes. The sample used is composed of a panel of vineyard farms, for the period 2000-2005, belonging to Portuguese Alentejo region. The methodology used to estimate technical efficiency, was the stochastic production frontier. The results showed that there are room to improve the levels of technical efficiency in input use and that efficiency is variant with time. It was observed that technical efficiency increases with economic size and net farm income, as well as with family entrepreneurship.efficiency, parametric, vineyard, Crop Production/Industries, Farm Management,
