Última Farmers' Subjective Valuation of Subsistence Crops: The Case of Traditional Maize in Mexico AgEcon Arslan, Aslihan; Taylor, J. Edward. Shadow prices guide farmers' resource allocations, but for subsistence farmers growing traditional crops, shadow prices may bear little relationship with market prices. We econometrically estimate shadow prices of maize using data from a nationally representative survey of rural households in Mexico. Shadow prices are significantly higher than the market price for traditional but not improved maize varieties. They are particularly high in the indigenous areas of southern and southeastern Mexico, indicating large de facto incentives to maintain traditional maize there.

Ano: 2008 URL: http://purl.umn.edu/44488 SHADOW PRICES OF SULFUR DIOXIDE ALLOWANCE IN PHASE I ELECTRIC UTILITIES AgEcon Rezek, Jon P.. The divergence of SO2 allowance price from initial estimates has spawned substantial interest since emission trading began. This paper uses non-parametric DEA to calculate technical, output revenue and allocative efficiency measures of Phase I electric plants. The allocative efficiency measure is then used to determine if allowance prices actually reflect opportunity costs.

Ano: 1999 URL: http://purl.umn.edu/21638 SHADOW PRICE OF ENVIRONMENTAL BADS: WEAK VS. STRONG DISPOSABILITY AgEcon Shaik, Saleem; Helmers, Glenn A.. This paper addresses the issue of the shadow price of environmental bads treated as an undesirable output (normal input) with weak (strong) disposability in a two-stage estimation. Nebraska agriculture sector time series data used is spread over 1936-94. Results indicate the difference in the price due to the disposability property.

The Malmquist index has become extensively used in international comparisons of agricultural productivity since it does not require prices for its estimation, which are normally not available. However, the DEA approach used to estimate this index still uses implicit price information. This entails potential problems because these methods are susceptible to the effect of data noise, and shadow prices can prove to be inconsistent with prior knowledge on cost shares. In this paper we analyze implicit input shadow shares used in the DEA approach to estimate agricultural productivity using the Malmquist index for 72 developing countries. We then set bounds to the implicit input shares introducing information on their likely value and compare constrained and...

Ano: 2009 URL: http://purl.umn.edu/51797 Measuring the Efficiency Effect of Banning Anti-Microbial Growth Promoters: The Case of Danish Pig Production AgEcon Lawson, Lartey Godwin; Sauer, Johannes; Jensen, Peter V.; Jensen, Helen H.. This study examines the effect of banning antimicrobial growth promoters on efficiency in the production of weaned and slaughter (finishing) pigs. We focus on the reaction of producers and production efficiency. We evaluate the estimated output and input shadow prices relative to market prices to analyse producer reactions and capture the impact on production efficiency by evaluating the effects of the ban changes on total factor productivity. To this end we model a multi product shadow profit function and incorporate output and input related shadow prices by using a second order flexible functional form. The development in total factor productivity is subsequently measured by calculating the Malmquist index on the farm level. To make infer-ences on the...

Ano: 2007 URL: http://purl.umn.edu/9995 Environmental Efficiency Among Corn Ethanol Plants AgEcon Sesmero, Juan P.; Perrin, Richard K.; Fulginiti, Lilyan E.. Economic viability of the US corn ethanol industry depends on prices, technical and economic efficiency of plants and on continuation of policy support. Public policy support is tied to the environmental efficiency of plants measured as their impact on emissions of greenhouse gases. This study evaluates the environmental efficiency of seven recently constructed ethanol plants in the North Central region of the U.S., using nonparametric data envelopment analysis (DEA). The minimum level of GHG emissions feasible with the available technology is calculated for each plant and this level is used to decompose environmental efficiency into its technical and allocative sources. Results show that, on average, plants in our sample may be able to reduce GHG...
