Article
Full-text available
The credibility of agricultural carbon credits will play a critical role in the determination of payments received by farmers through voluntary carbon markets. This article analyzes the major challenges from both the demand and supply sides to voluntary agricultural carbon credit programs and serves as a resource to researchers, producers, policyma...
Article
Full-text available
The emerging agriculture credits market can be currently characterized as an unarticulated patch of coexisting programs with different rules, incentives, and penalties, rather than as a cohesive and transparent market where the same activity has the same implication across programs. In its formative stage, the incipient agriculture credits market i...
Article
Full-text available
Conservation practices such as no-till and cover crops have been shown to have on- and off-farm benefits. However, when benefits of a practice do not go to the provider, underinvestment may occur. Farmland rental arrangements where tenants may not reap the benefits of conservation investments are a commonly cited barrier to conservation practice ad...
Article
Full-text available
Cover crops can generate both on-farm and water-quality benefits. However, their use in Iowa remains subdued, partly due to implementation costs faced by farmers. We tested the hypothesis that monetary incentives through cost-share programs are effective at increasing the area of farmland planted to cover crops in Iowa, as opposed to the alternativ...
Article
Full-text available
This study illustrates and quantifies how overlooking the impact of weather shocks can affect the measurement and decomposition of agricultural total factor productivity (TFP) change. The underlying technology is represented by a flexible input distance function with quasi‐fixed inputs estimated with Bayesian methods. Using agricultural production...
Conference Paper
Full-text available
Changes to productivity on the farm could have implications for productivity in other segments of the economy. Identifying these productivity linkages can help reveal synergies between agriculture and other industries in an effort to promote economic growth or to dampen negative spillovers that may also occur.
Article
Full-text available
Cover crops are becoming more accepted as a viable best management practice because of their ability to provide important environmental and soil health benefits. Because of these benefits, many land managers are strongly encouraging the use of cover crops. Additionally, there is limited information on farmers′ perceptions of the benefits and challe...
Article
Georgia is the second largest producer of cotton and the largest producer of peanuts in the United States. These crops combined represent a significant portion of Georgia's economy. As natural resources become more threatened, the cotton and peanut industries have been facing increasing challenges to improve environmental sustainability. This resea...
Presentation
Full-text available
Alternative sources of demand for sustainability in agricultural production are discussed, along with the associated challenges and opportunities presented to American farmers and ranchers. Four major roles for Land Grant Universities' Extension Services are identified to better serve stakeholders in this area.
Article
Cover crops provide environmental services that can effectively reduce the negative impacts from otherwise highly productive row-crop systems in the US Midwest. In this context, winter rye is the most commonly used cover crop among producers because it overwinters and produces considerable biomass in the spring. While the soil and water benefits of...
Article
Full-text available
Land grant universities hold a trusted brand in the agriculture sector and have been a source of reliable and unbiased information for a long time. However, ongoing population, sociological, and technological trends are undermining the relevance of extension services as we know them. The future of farm management extension is tied to the future of...
Article
Agricultural production studies are usually conducted using classical econometrics that make it difficult, if not impossible, to impose conditions derived from economic theory on flexible functional forms. Therefore, such conditions need not hold in estimation. We apply Bayesian econometrics to estimate a flexible production function using U.S. agr...
Article
Full-text available
Despite the active promotion of cover crops as a key conservation practice, their adoption is very limited. We developed a series of partial budgets based on a statewide survey of Iowa farmers to evaluate the changes in net returns resulting from the incorporation of cover crops into a corn or soybean production system. The average net returns to c...
Technical Report
Full-text available
Farmland is arguably often a farmer’s single largest investment item, a major source of collateral, and a key component of the farmer’s debt portfolio. At the macro level, the value of land and buildings represent over 80 percent of all U.S. farm assets. As a result, changes in the farmland market and the implications for farmland owners, tenants,...
Article
Full-text available
This study uses partial budgets to assess the annual net private economic returns to cover crop use in Midwest row crop farms. Data were compiled through an online survey to farm operators that manage production systems with and without cover crops. The average net returns to cover crops terminated with herbicides followed by corn was negative, but...
Article
Full-text available
Despite being generally accepted as a promising conservation practice to reduce nitrate pollution and promote soil sustainability, cover crop adoption in Midwestern US agriculture is low. Based on focus groups, surveys and partial budgets, we calculated the annual net returns to cover crop use for farmers in Illinois, Iowa and Minnesota; and elicit...
Article
Full-text available
The present study aims at improving our understanding of the individual contribution of the components of total factor productivity (TFP) change to U.S. agricultural productivity. A novel sequential primal-dual estimation routine to calculate TFP change is proposed, using a multi-output input distance function in the first stage, followed by a cost...
Article
Full-text available
Perennial bioenergy crops are considered an important feedstock for a growing bioeconomy. However, in the USA, production of biofuel from these dedicated, nonfood crops is lagging behind federal mandates and markets have yet to develop. Most studies on the economic potential of perennial biofuel crops have concluded that even high‐yielding bioenerg...

Full-text available
This paper uses panel data for the 1980-2004 period to estimate the contributions of public research to US agricultural productivity growth. Local and social internal rates of return are estimated accounting for the effects of R & D spill-in, extension activities and road density. R & D spill-in proxies were constructed based on both geographic pro...

This volume is written primarily for agricultural economists doing research on productivity. It includes discussions of the theoretical underpinnings of productivity measurement as well as the many practical considerations that go into translating this theory into actual measures of aggregated outputs and inputs. The unifying concept of agricultura...
Article
The increases in cotton fibre prices which occurred between August 2010 and August 2011 were steeper than at any time since records began. Moreover, because the movements were unprecedented, no one knew for certain how much, or how quickly, those increases would affect the prices of yarns, fabrics and apparel in the manufacturing supply chain, and...
Article
Cotton is among the most internationally traded agricultural commodities. As a result, cotton prices are often described in terms of a world price. This world price, called the A Index, has been published by the trade group Cotlook since the mid-1960’s and is generally accepted as representative of a global price for cotton. As a world price, the A...

Article
Full-text available
This study provides a new framework of analysis of the market and welfare effects of mandatory country-of-origin labeling (MCOOL) for fruits and vegetables that accounts for heterogeneous consumer preferences, differences in producer agronomic characteristics, and retailer market power. The market and welfare effects of MCOOL are shown to be case-s...
Article
Full-text available
A common question when analyzing supply chains is how much a change in input costs at one stage in the supply chain affect prices downstream. To address this question, research has been conducted that examines the extent that changes in prices are “passed-through.” Much of the pass-through research that has been conducted has been focused on change...
Article
Full-text available
Alternative trade organizations (ATOs) based on philosophies of social justice and/or encironmental well-being are establishing new channels of trade and marketing. Partisans promote ATOs as systems to transfer benefits from consumers in the wealthy northern hemisphere to producers in the poor southern hemisphere. The central public policy question...
Article
Cotton price has climbed since the beginning of this year to levels far beyond the projections made by various market watchers, including the World Bank. This study analyses the flow of investment funds as well as the composition of the cotton futures and options markets and sheds some light on the price spiral.

The present study adopts a survey methodology designed to measure a combination of socio-economic impact indicators as well as measures particular to the Fair Trade coffee growing and m...
Article
Full-text available
This paper analyzes the market and welfare effects of the introduction of GM products in small open developing economies that, prior to the adoption of GM crops, were net exporters of non-GM products. It explicitly accounts for differences in consumer attitudes towards GM products and producer agronomic characteristics as well as for the structure...
Article
Full-text available
Third party certification processes have been proposed as a mechanism to deal with adverse selection in the newly industrialized agricultural sector. But their appropriateness heavily relies on the accuracy of detection of the low quality types by the certification agency. Once the assumption of perfect certification is relaxed, moral hazard issues...
Article
In this paper we revisit the issue on the impact of public R&D expenditure on US agricultural productivity growth. We estimate a dual cost function using a state-by-year panel data set. We construct the potential R&D “spillins” based on both geographical location and production mix. We also examine the role of the extension service, transportation...
