A theoretical model of a landowner’s optimal bid is presented, and we demonstrate the ambiguity in a landowner’s optimal bid response to CPA designations. The bid choice is analyzed using a data set of accepted and unaccepted offers during three CRP sign-up periods. We focus empirically on a subset of offers from the Prairie Pothole CPA to identify whether bid responses to exogenous location factors differ across landowners with varying opportunity costs to enrollment.

The CRP pays farmers to remove chosen plots of land from agricultural production and put them to a conservation use. An interesting aspect of this auction is that winners are determined by a combination of low bids and environmental scores of individual plots. Using decision theoretic approach to model this auction we show that farmers condition their bids on the strength of their environmental scores and that they value environmental benefits, especially those that increase future soil productivity of their land.}, number={6}, journal={INTERNATIONAL JOURNAL OF INDUSTRIAL ORGANIZATION}, author={Vukina, Tomislav and Zheng, Xiaoyong and Marra, Michele and Levy, Amando}, year={2008}, month={Nov}, pages={1323–1332} }

Although they have been emphasized in many commentaries about the adoption process, they have been directly addressed in only a minority of the large literature relating to the adoption of innovations. Risk, uncertainty and learning play a number of distinct roles in the process of adopting new technologies. These distinct roles have often been blurred or treated incompletely in past research. Theoretical and empirical literature, which explores and evaluates these various roles is reviewed, with a focus on agricultural technologies.

Using estimated demand equations, we simulate the costs of reducing conventional insecticide applications through subsidization of Bt cotton. Results indicate that reducing cotton insecticide applications by 40% in the Southeast would require a $@@‐@@21/acre subsidy, with total annual program costs between $@@‐@@53 million and $@@‐@@60 million.}, number={1}, journal={AMERICAN JOURNAL OF AGRICULTURAL ECONOMICS}, author={Hubbell, BJ and Marra, MC and Carlson, GA}, year={2000}, month={Feb}, pages={118–132} }

In all, enough information was collected from the literature for 321 separate profitability results including 120 direct comparisons of organic production to conventional and 144 no-till vs. conventional direct comparisons for North American grains for a meta-analysis. The first part of the analysis was a standard, descriptive summary of the data. This showed that the relative profitability of organic production was, on average, higher for corn and grain sorghum and if the research was conducted at a research experiment station. No-till averaged higher profitability in on-farm trials and with oilseeds, corn and grain sorghum in the descriptive analysis. Then the study proceeded with a meta-analysis of the economic comparisons. The meta-analysis results indicated that study location (Eastern, Central or Western North America) was a key factor in explaining the relative profitability of each alternative cropping system relative to the conventional system. In addition, study type (on-farm or research station experiment) and type of grain crop (small grain, oilseed, other) were important in explaining the relative profitability of both systems.}, number={4}, journal={JOURNAL OF SUSTAINABLE AGRICULTURE}, author={Marra, MC and Kaval, P}, year={2000}, pages={19–32} }

The model outcomes are predictions of various economic measures, including the coefficient of variation of net returns for corn, wheat, soy-beans, and cotton. Then Knutson et al. use the results of the Ray et al. simulations to predict the distribution of net farm income over the next 10 years for several types of representative southern farms. Any attempt to measure the changes in riskiness in southern agriculture is commendable—even heroic—and I applaud these efforts, both the national modeling effort by Ray et al. and the application to southern representative farms by Knutson et al. This task has a lot in common, I think, with trying to “tease out” the temperature changes associated with the greenhouse effect. The number of factors and mechanisms at work is mind-boggling. It's tough enough to try to get a handle on what might happen to the first moment of net farm income over the next 10 years, let alone the second.}, number={1}, journal={Journal of Agricultural and Applied Economics}, author={Marra, M.
