Tracking urban sprawl: Using spatial data to inform farmland preservation policy

The development of state farmland preservation policies has primarily relied upon results of the Census of Agriculture that is updated every 5 years by the USDA National Agriculture Statistics Service. Questions about the suitability of the Census of Agriculture center on the measures of total farmland and total cropland as reported by agricultural producers. The reliance on these variables fails to distinguish between conversion to developed uses and other fluctuations in the total availability of farmland. This inability to directly measure farmland conversion to developed uses has been shown to influence state level farmland preservation policies. The policies of Illinois and Indiana highlight the disparate approaches, with Illinois pursuing an intensive policy to protect farmland and Indiana choosing to not address farmland preservation at a state level. In order to assess the suitability of the different approaches to farmland preservation policy it is critical to evaluate the Census of Agriculture data used to justify the policies of Illinois and Indiana.     

Measuring the effect of farmland preservation on farm profitability

Purchase of development rights (PDR) programs have been created in 27 states to preserve farmland resources. These programs seek to advance several societal objectives, including the protection of farmland from development, retention of rural amenities, and promotion of the economic viability of farming. Using New Jersey farm-level data, this study evaluates whether participation in a state PDR program improves farm profitability. The propensity score matching method is used to correct for selection bias arising from the voluntary nature of these programs. No statistically significant profit differential is found between preserved and observationally equivalent unpreserved farms in our full sample of 4029 farms. When the analysis is replicated across different farm types, we find weak evidence that the profitability of preserved residential lifestyle/retirement farms is lower than that observed for their unpreserved equivalents. In contrast, we find that small farms (<$100,000 in annual sales) operated by individuals for whom farming is a principal occupation earn $414 to $436 more per acre in profit than their observationally equivalent unpreserved counterparts.     

Characteristics of Successful Southeastern U.S. Agribusiness Exporters

Abstract

A survey of southeastern U.S. agribusiness exporters showed that export firms had many characteristics in common regardless of commodity category. In general, the profile of a successful southeastern U.S. agribusiness exporter in terms of export sales is one that tends to have higher total sales, foreign and domestic, and more export-market experience though the firm tends to be relatively young. While almost half of the firms engaged in promotion activities, less than a quarter of the respondents availed themselves of federal export promotion/assistance programs because of unfamiliarity or perceived costs. An overwhelming majority considered freight forwarding companies as indispensable parties to all transactions because of the extreme complexity of export-import logistics.     

How financial investment distorts food prices: evidence from U.S. grain markets

Convergence between commodity futures prices and the underlying physical assets at each contract's expiration date is a pivotal condition for the market's functioning. Between 2005 and 2010, convergence failed for several U.S. grain markets. This article presents a price pressure‐augmented commodity storage model that links the scale of nonconvergence to financial investment channeled through indices, which are traded in commodity futures markets. The model is empirically tested, using Markov regime‐switching regression analysis. Regression results strongly support the model's predicted link between index investment and the extent of nonconvergence for three grains traded at the Chicago Board of Trade: wheat, corn, and soybeans.     

The effects of farmland use rights trading and labor outmigration on the governance of the irrigation commons: Evidence from China

The governance of the commons depends on collective action by resource users, which may be influenced by land use dynamics and changes in livelihood. We examine the case of China that has experienced massive outmigration of its rural population and significant changes to its land use policy. We contribute to the literature by examining the interaction effects of farmland use rights trading and rural labor out migration on collective action for the governance of the irrigation commons, which has the potential to open up a new line of theoretical and empirical inquiry. Using the socio-ecological system framework, we run ordered probit regression based on data from a survey of 125 villages in 18 provinces in China. We find that a moderate degree of farmland use rights trading has a positive effect on collective action for the governance of the irrigation commons and can slow down and mitigate the negative effect of rural labor outmigration. We conclude with implications for land use policy and governance of the commons.     

Long-run impacts of trade shocks and export competitiveness: Evidence from the U.S. BSE event

This paper examines how comparative advantages of major beef exporters changed following the 2003 bovine spongiform encephalopathy (BSE) outbreak, which significantly disrupted the U.S. beef trade until approximately 2007. Using longitudinal data on beef export values and constructed revealed comparative advantage measures, we show that while some measures of the long-run impacts of BSE on U.S. beef export competitiveness have returned to pre-2003 levels, the U.S.’s comparative advantage has not. We also examine a hypothetical scenario of no BSE event in 2003 and predict that in the absence of the BSE outbreak, the U.S. beef sector would have been increasingly more competitive by 2017 than it actually was. Long-term trade competitiveness may not simply return to normal even after a short-term disruption.

Earnings Management through Specific Accruals and Discretionary Expenses: Evidence from U.S. Agribusiness Firms

This study examines both accruals based earnings management (AEM) and real earnings management (REM) in U.S. agribusinesses. In particular, the focus is on agribusinesses that report low earnings quality, defined as firms with extreme level of accruals compared to their peers. The cross‐sectional modified Jones model (Jones 1991; Dechow et al 1995) is used to test for AEM. To capture REM practices, we implement the discretionary expenses model by Roychowdhury (2006). We find evidence of AEM and find no evidence of REM in agribusinesses. In addition, our results show that managers might be managing earnings through specific accruals doubtful accounts receivable provisions and special items.     

Mergers and Acquisitions and Productivity in the U.S. Meat Products Industries: Evidence from the Micro Data

This article investigates the motives for mergers and acquisitions (M&As) in the U.S. meat products industry from 1977 to 1992. Results show that acquired meat and poultry plants were very productive before mergers, and that all but the very largest meat slaughter and processing plants and all but the bottom 20% of the poultry slaughter and processing plants significantly improved their productivity growth in their postmerger periods. These results lead to the conclusion that synergies and related efficiencies are important motives for M&As.     

Analyzing the behavioural mechanism of farmland abandonment in the hilly mountainous areas in China from the perspective of farming household diversity

Revealing the mechanism under the occurrence of farmland abandonment from the perspective of farming household diversity is conducive to proposing well-directed farmland protection policies. With a thorough consideration and study of cases in some hilly mountainous areas in China, this paper uses behaviour decision models of farming households to systematically understand and analyse the behavioural mechanism leading to farmland abandonment by different types of farming households, including aged households, stable part-time households, unstable part-time households and pure households. The mechanism is empirically analysed with a logistic regression model by household survey data collected from Jiangxi and Guizhou, 2 Chinese provinces, and the results observed as follows: (1) age is a key determinant of farmland abandonment of aged households, and as the age of farm labourers increases by one year, the probability of farmland abandonment increases by 8.5 %; (2) off-farm labourers is a key determinant of farmland abandonment of stable part-time households, and for each additional number of off-farm labourers, the abandonment probability increases by 41.4 %; (3) plot features such as land quality, irrigation and distance to home, are the main determinants affecting farmland abandonment of pure households; and (4) high possibility for unstable part-time households not to abandon farmland. A series of policy measures targeted for diverse farming households are therefore finally proposed to alleviate the farmland abandonment in hilly mountainous areas and other areas with similar problems.     

Prioritising land to be preserved for agriculture: A context-specific value tree

In Belgium as in many other countries, agricultural land is under pressure for development of other land uses. This paper presents a method for setting priorities for preservation of land for agriculture. The method is based on a participatory approach through which a value tree is formulated. This results in a list of criteria to define farmland value, which is explicitly linked to the objectives for farmland preservation. The value tree allows the list of criteria to be determined in a structured and consistent way. The participatory process contributes to the development of a shared vision on farmland preservation. The approach also incorporates context specificity, as shown by its application for farmland preservation in Flanders.     

Governing farmland conversion: Comparing China with the Netherlands and Germany

Farmland conversion has become an increasing concern in China and other parts of the world, including Europe and the USA. Be it for environmental or food security reasons, questions arise concerning how urbanization should be governed, i.e. what rules and regulations could enhance the efficiency and sustainability of land use. Taking a first step toward answering such questions, this paper describes different governance structures for farmland conversion in the Netherlands, Germany, and China. Secondly, it compares five identified differences between these countries in the realms of land property, land use planning, the role of the market, the role of government, and the performance of governance structures. The purpose of this paper is to develop an approach for comparing governance structures for land conversion that: (a) offers some opportunities for exchange of experience between the three countries and (b) provides a framework for further research on governance structures in farmland conversion.     

Impacts of Policy Reforms on the Supply of Mexican Labor to U.S. Farms: New Evidence from Mexico

The availability of immigrant farm-workers from Mexico is a critical factor affecting the U.S. fresh fruit and vegetable sector. This paper uses retrospective panel data from rural Mexico to examine the impact of the North American Free Trade Agreement and the Immigration Reform and Control Act on the supply of migrant labor to the United States. We find that, in contrast to expectations, both policies were associated with an increase in migration to U.S. farm jobs from rural Mexico.

Slotting Fees for Organic Retail Products: Evidence From a Survey of U.S. Food Retailers

Based on a survey of U.S. food retailers, our study finds that almost one third of U.S. food retailers charge slotting fees for certified organic food products, a retailing area where slotting fees had not previously been well documented. Econometric results from both ordered response and binary response models suggest that a number of firm-level attributes do influence the presence and/or relative size of organic slotting fees in a manner that is mostly consistent with an economic efficiency rationale and partly consistent with a market power/strategic behavior rationale for slotting fees.     

Measuring public agricultural research and extension and estimating their impacts on agricultural productivity: new insights from U.S. evidence

This article provides new estimates of the marginal product of public agricultural research and extension on state agricultural productivity for the U.S., using updated data and definitions, and forecasts of future agricultural productivity growth by state. The underlying rationale for a number of important decisions that underlie the data used in cost‐return estimates for public agricultural research and extension are presented. The parameters of the state productivity model are estimated from a panel of contiguous U.S. 48 states from 1970 to 2004. Public research and extension are shown to be substitutes rather than complements. The econometric model of state agricultural TFP predicts growth rates of TFP for two‐thirds of states that is less than the past trend rate. The results and data indicate a real social rate of return to public investments in agricultural research of 67% and to agricultural extension of 100+%. The article concludes with guidance for TFP analyses in other countries.     

An analysis of bundle pricing in horizontal and vertical markets: The case of the U.S. cottonseed market

The U.S. cottonseed market has seen the rapid development and adoption of seeds with differing bundles of genetically modified (GM) traits. It has also seen an increase in vertical integration by biotechnology firms. In this article, we investigate the price impacts associated with structural changes in the U.S. cottonseed market from 2002 to 2007. We develop a structural model to examine the substitution/complementarity relationships among cottonseeds sold with different genetic trait bundles and under different vertical arrangements. We examine the price impacts emanating from product differentiation, market concentration, and market size. The econometric investigation finds evidence of subadditive bundle pricing in patented biotech traits. While higher own‐market concentrations are found to be associated with higher prices, we also uncover evidence of cross‐product complementarity effects that lead to lower prices. Simulations are used to evaluate net price effects, illustrating the usefulness of the approach in the analysis of changing market structures.     

Planning for social inclusion: The impact of socioeconomic inequities on the informal development of farmland in suburban Beijing

Informal development on farmland is not only a major problem facing thousands of people, but also a major challenge to land use planning. In the rapidly growing literature on informal land development in China, most authors claim that ambiguous property rights and the dual land tenure system are the primary factors involved. As a result, existing state-led land use planning responses to informal development are solely focused on strengthening the legal regulation of land development. This paper challenges this approach, on the basis of the theory of urban informality. By examining many illegal gated communities in suburban Beijing, the paper argues that the informal development of farmland on the urban fringe is the result of local grassroots groups spontaneously responding to socioeconomic inequities in the context of transition to a market economy. These inequities mainly concern distributive inequity, procedural inequity and contextual inequity in relation to land use. It appears that the ongoing market-oriented initiatives of the state government could worsen informal land development unless these socioeconomic inequalities at the local level are tackled. The growing civil society is another change to the state's control of informal land development in China's cities. A new land use planning system which has more concern for social inclusion rather than focusing on centralized control is imperative in China.
