Farmers markets could be considered the historical flagship of local food systems, and their numbers in the US have grown significantly over the last decade, a 150% increase from 1994 through 2006 (AMS 2007). Total nationwide sales for the 2005 season were estimated at $1 billion, reflecting 13% sales growth since 2000 (USDA 2006). Community Supported Agriculture (CSA) is a marketing strategy where consumers buy \"shares\" in the farm before planting begins and receive a portion of whatever is available each week of the growing season. These shares generally cost several hundred dollars and provide enough fresh produce for a family; some shares include other products, such as eggs, honey, flowers, and/or meat. This review of literature focuses on research that examines the impacts that CSA and farmers markets have on farmers, consumers, and communities, following up on Brown's (2002) findings by reviewing research conducted on farmers markets since 2000.

Antibiotic effectiveness can be viewed as a biological commons since one individual's current use may decrease future effectiveness for everyone else. The value of the biological commons declines when the targeted bacteria develop antibiotic resistance. Antibiotic resistance is a global threat to health and development, causing serious economic damage and loss of human lives. The greatest share of antibiotics is used in livestock production, leading to concerns that such use may threaten human health. While various policies are in place to promote judicious use of antibiotics, their effectiveness is unclear. One key challenge in antibiotics management is the uncertainty surrounding various decisions related to antibiotic use, including whether a suspect case has an infection, how likely an infection will spread, and how effective antibiotics can be if used. We develop a disease management model that incorporates linkages among diagnostic testing decisions, antibiotic use decisions, and alternative treatment costs. We show that many unintended consequences may arise from policies designed to promote judicious antibiotic use. Antibiotics and self-tests are complements (substitutes) whenever antibiotic cost is high (low), implying that a self-test subsidy can plausibly increase expected antibiotic use. With regard to a prescription regulation (PR) that switches an antibiotic from over-the-counter to prescription, we show that while PR can reduce therapeutic antibiotic use as intended it may not achieve the social optimum. In a simple real-world application, we find that PR induces excessive veterinary service demand but does not reduce antibiotic use among typical U.S. dairy farms. PR also leads to the substitution of veterinary services for self-tests in obtaining information. We discuss how our analytical framework can be applied to other contexts, including antibiotics for human use.

This article adopts a long-term perspective to examine Indian agricultural data: from crop yields for estimating food output, the examination of food prices and wages for calculating income and living standards, to the status of food consumption to ascertain hunger and malnutrition. The focus will be on the evaluation of how the new statistical data collection methods that emerged in the early decades of twentieth century have impacted the field of development economics in India. It makes the case that the emergence of survey methods data that were initially created by officials and later on by professionals employed in institutions in India were novel and began to gain attention in the international sphere. It proceeds to underline the importance of these statistical databases for identifying the minimum standard of living to escape poverty as an important measure for ascertaining how national development strategy could reduce poverty and hunger and also shows that these databases proved to be a core resource for unpicking recent puzzles regarding food and nutrition levels among the poorer sections of society. Additionally, the article engages with more recent estimation methods where survey-based agricultural statistical databases have been incorporated in multi-scalar indices alongside meteorological and ecological data to create more informative agricultural databases to advance the objective of sustainable agricultural development in India.

Recent food scares such as the discoveries of Bovine Spongiform Encephalopathy and E. coli-contaminated spinach have heightened interest in food traceability. Here, we show how exogenous increases in food traceability create incentives for farms and marketing firms to supply safer food by increasing liability costs. We model a stylized marketing chain composed of farms, marketers, and consumers. Unsafe food for consumers can be caused by either marketers or farms. We show that food safety declines with the number of farms and marketers and imperfect traceability from consumers to marketers dampens liability incentives to supply safer food by farms.

Esophageal hypersensitivity is currently believed to have a crucial role in the pathogenesis of functional chest pain (FCP). The aim of this study was to evaluate the clinical efficacy of venlafaxine, a serotonin-norepinephrine reuptake inhibitor (SNRI), for FCP in young adult patients. Patients diagnosed with FCP were randomized to either an extended-release formulation of venlafaxine (75 mg hora somni) or a placebo for 4 weeks. After a washout period of 2 weeks, patients crossed over to the other arm of the study. The primary efficacy variable was the number of patients with >50% improvement in symptom scores. The secondary efficacy variables were (i) the symptom intensity score during each week, (ii) quality of life (QOL), (iii) the Beck Depression Inventory (BDI) score, and (iv) side effects. A total of 43 patients (37 men, mean age 23.5 + or - 1.9 years) completed the study. A positive response was observed in 52.0% of patients during venlafaxine treatment; 4.0% had a positive response with placebo treatment as assessed by the intention-to-treat analysis (venlafaxine vs. placebo: odds ratio 26.0; 95% confidence interval 5.7-118.8; P<0.001). Results of Short-Form 36 (SF-36) indicated that patients who received venlafaxine treatment had a significantly greater improvement in body pain and emotional role compared with those who received placebo treatment (P=0.002 and P=0.002, respectively). No significant change was noted in the depression score after venalafaxine or placebo treatment. One patient withdrew from the study because of sleep disturbance and loss of appetite while receiving venlafaxine. Venlafaxine, an SNRI antidepressant, significantly improved symptoms in young adult patients with FCP.

The relationship between Food Stamp Program (FSP) participation and household food insecurity (FI) is investigated using data from the 1996-1997 National Food Stamp Program Survey. Endogeneity of FSP participation is accommodated with an instrumental variables approach. In contrast to other findings reported in the literature, results suggest participation in the FSP reduces the severity of FI. Sociodemographic variables play important roles in FSP participation and FI. Underreporting of FSP participation and limited observations of food-insecure households in previous studies may have also been factors.

A theoretical model of consumer response to publicized food safety information on meat demand is developed with an empirical application to U.S. meat consumption. Evidence is found for the existence of pre-committed levels of consumption, seasonal factors, time trends, and contemporaneous own- and cross-commodity food safety concerns. The average demand response to food safety concerns is small, especially in comparison to price effects, and to previous estimates of health related issues. This small average effect masks periods of significantly larger responses corresponding with prominent food safety events, but these larger impacts are short-lived with no apparent food safety lagged effects on demand.

This analysis utilizes farm-level data to evaluate the extent to which U.S. farm program benefits, particularly direct payments, bring about distortions in production. The issue is important in WTO negotiations and in the debate over the distortionary effects of decoupled (\"green-box\") payments. Our results suggest that the distortions brought about by AMTA payments, though statistically significant in some cases, are very modest. Larger effects are implied for market loss assistance payments. Probit models suggest that AMTA payments do not influence the likelihood that agents will acquire more land. Our results are reinforced using an aggregate county-level acreage model.

The extent to which crop insurance programs have resulted in additional land being brought into production has been a topic of considerable debate. We consider multiequation structural models of acreage response, insurance participation, CRP enrollment, and input usage. Our analysis focuses on corn and soybean production in the Corn Belt and wheat and barley production in the Upper Great Plains. Our results confirm that increased participation in insurance programs provokes statistically significant acreage responses in some cases, though the response is very modest in every case. In the most extreme cases, 30% decreases in premiums as a result of increased subsidies provoke acreage increases ranging from 0.2% to 1.1%. A number of policy simulations involving increases in premium subsidies are considered.

Both bodies of the U.S. Congress have recently considered legislation to restrict use of antibiotics in livestock feed. Although several studies have addressed the costs of such restrictions, little is known about consumer demand. This study estimates consumers' willingness to pay for pork produced without subtherapeutic antibiotics and consumers' willingness to contribute to a reduction in antibiotic resistance by collecting data in a grocery store environment with mechanisms that involve the exchange of real food and real money. Results indicate that the welfare effects of a ban depend heavily on assumptions about consumers' current knowledge about antibiotic use in pork production and the extent to which consumers are currently able to purchase antibiotic-free pork.
