| Over the last twenty five years commodity crop farms have steadily declined in number and grown in average size, and production has shifted to larger operations. During the same period, the share of agricultural payments going to large farms has increased, in large part because payments are tied to actual or historical crop production. This study evaluates whether payments from federal farm programs may have contributed to the concentration of farmland. Using zip code-level data constructed from the micro files of the 1987-2002 Agriculture Censuses the study estimates the association between government payments per acre and subsequent growth in weighted median farmland area. A semi-parametric generalized additive model controls for location and initial... |

| Previous research has found that on-farm income variability helps determine off-farm labor supply. However, unobserved heterogeneity of farms or regions may have biased earlier results. In this study, we use an exogenous increase in Federal crop insurance subsidies as a natural experiment to identify the importance of risk in off-farm labor supply. The subsidy increases induced greater participation in crop insurance programs and thereby reduced farmers' financial risks. By merging county-level crop insurance participation data with farm-level Agricultural Census data from 1992 and 1997 we can compare the off-farm labor decisions of individual farms before and after the subsidy and thereby control for unobserved heterogeneity. Unlike previous studies, we... |

| Nearly all farm business ventures involve financial risk. In some instances, private and public tools used to manage financial risks in agriculture may influence farmers' production decisions. These decisions, in turn, can influence environmental quality. This bulletin summarizes research and provides some perspective on private and public attempts to cope with financial risks and their unintended environmental consequences. Specifically, it examines the conceptual underpinnings of risk-related research, challenges involved with measuring the consequences of risk for agricultural production decisions, government programs that influence the risk and return of farm businesses, and how production decisions influence both the environment and the risk and... |

| We examine changes in land use caused by the large increase in crop insurance premium subsidies under the 1994 Federal Crop Insurance and Reform Act (FCIRA). We use a conditional logit model to estimate changes in six major land uses from 1992 and 1997 as a function of the change in expected return to crop insurance. Our data on individual land parcels across the entire coterminous United States enable identification of the extent, location, and physical characteristics of the land brought into and retained in production as a result of the crop insurance policies. Results indicate the additional crop insurance premium subsidies increased cultivated cropland area on the order of 1.9 million acres (0.6%), consistent with the lower range of previous... |

| This study makes use of farm-level data from the Agricultural Census to evaluate the effects of the 1996 Federal Agriculture Improvement and Reform (FAIR) Act, which intended to "decouple" commodity payments from production decisions. Prior to this Act, agricultural support payments were linked to production decisions via prices and a complex set of restrictions that acted to control the supply of agricultural commodities. We compare farm-level 1992-to-1997 changes in commodity crop plantings of farms that participated in government programs with farms that did not participate. We find that the growth rate of program-crop acreage of non-participants was 19 percentage points below that of participants. This estimated difference remains unchanged after... |

| The studies in this report analyze the effects of decoupled payments in the Federal Agriculture Improvement and Reform (FAIR) Act on recipient households, and assess land, labor, risk management, and capital market conditions that can lead to links between decoupled payments and production choices. Each study contributes a different perspective to understanding the response of U.S. farm households and production to decoupled income transfers. Some use new microdata on farm households collected through USDA's Agricultural Resource Management Survey (ARMS), initiated in 1996, and its predecessor survey. These data are used to compare household and producer behavior and outcomes before and after the FAIR Act. Other studies use applied or conceptual models to... |

| Farm income is highly variable due to annual price and yield uncertainties. The federally subsidized crop insurance program is an important tool for managing this risk, and has grown from a relatively modest program to one that encompasses the majority of productive cropland in the country. The success of this program depends on identification of actuarially fair insurance premium rates, which in turn depends on accurate estimation of farm-level yield distributions. We use the confidential U.S. Department of Agriculture Risk Management Agency (RMA) panel dataset to estimate farm-specific distributions of yields and actually fair crop insurance premiums. Our ongoing work includes using the difference between our estimated actually fair premiums and RMA's to... |

| Early-warning systems for plant diseases are valuable when the systems provide timely forecasts that farmers can use to inform their pest management decisions. To evaluate the value of the systems, this study examines, as a case study, USDA’s coordinated framework for soybean rust surveillance, reporting, prediction, and management, which was developed before the 2005 growing season. The framework’s linchpin is a website that provides real-time, county-level information on the spread of the disease. The study assesses the value of the information tool to farmers and factors that influence that value. The information’s value depends most heavily on farmers’ perceptions of the forecast’s accuracy. The study finds that the framework’s information is valuable... |

| We use administrative data from the Federal crop insurance program to examine how yield distributions change as farmers cycle into and out of the program. We are able to do this by linking many years of crop insurance data by individual farm conditioning observed yields on the particular county and year in which they are observed. Armed with millions of observations, we examine many states and five major crops: corn, soybeans, wheat, rice and cotton. We find little evidence that yield distributions are affected by insurance. An exception is rice in Arkansas, where insurance shifts the distribution markedly downward. |

| The idea that agricultural subsidies are fully capitalized into farmland values forms the foundation of the argument that subsidies are entitlements and removing them would drastically reduce farmland asset values. Surprisingly little evidence substantiates this claim. Using field-level data and explicitly controlling for potentially confounding variables we find that landlords only capture between 14 – 24 cents of the marginal subsidy dollar. The duration of the rental arrangement has a substantial effect on the incidence. Initially, landlords extract 44 cents of the marginal subsidy dollar, but the incidence falls by 1.5 cents with each additional year of the rental arrangement. This duration effect reveals that rental market frictions play an important... |

| Previous research finds that some environmental benefits stemming from the Conservation Reserve Program (CRP) are offset by slippage: farmers simply plant more acreage to substitute for land that was idled. Our analysis shows that previous slippage estimates likely stem from spurious correlation. Most land retired under CRP is of lower-than-average quality. Due to the marginal economic viability of these lands they also are more likely to move both into and out of agricultural production. CRP enrollments therefore will be spatially correlated with non-cropland to cropland conversions even if no slippage is present. Using time-series rather than cross-sectional variation in CRP enrollments, we obtain new slippage estimates that control for land... |

| This report examines evidence on the relationship between agricultural land-use changes, soil productivity, and indicators of environmental sensitivity. If cropland that shifts in and out of production is less productive and more environmentally sensitive than other cropland, policy-induced changes in land use could have production effects that are smaller-and environmental impacts that are greater-than anticipated. To illustrate this possibility, this report examines environmental outcomes stemming from landuse conversion caused by two agricultural programs that others have identified as potentially having important influences on land use and environmental quality: Federal crop insurance subsidies and the Conservation Reserve Program (CRP), the Nation's... |

| Farm-level Census data and county-level income shock data reveal that past unexpected income shocks affect the rate of change in average farm size. Average farm size increases more quickly in counties experiencing negative income shocks as compared to counties experiencing positive income shocks. This result cannot be explained by perfect-market models, which predict farm size should adjust according to changes in the relative prices of labor and capital. We posit a model wherein cash flows affect liquidity, which in turn affects farm borrowing and capital costs. In the model, farms that do not face liquidity constraints benefit from negative income shocks because they reduce land values, so these farms expand while liquidity-constrained farms contract.... |

| Economic theory suggests several possible mechanisms through which direct government farm payments might influence the pattern of structural change in agriculture. This study estimates what effect farm payments have had on farm structure using farm-level panel data from the 1987, 1992, and 1997 Agricultural Censuses. Results suggest that the size of per-acre payments received in the past are associated with a small and weakly positive change in farm size between consecutive censuses, but that payments are significantly correlated with an increased likelihood of farm survival between consecutive periods. |
