| A real options model is developed to examine the determinants of farmer participation in the Conservation Reserve Program (CRP). This study contributes to the literature by developing a framework for ex post analysis of uncertainty and irreversibility. It extends the applications of real options models to analyze farmer participation in the CRP. The model incorporates land and owner attributes, and determines whether uncertainty and irreversibility affect the probability of participation. Option values play a significant role in farmer decisions to retire land by reducing the probability of participation. These results have implications for the design and implementation of conservation programs. |

| To avoid the abuse and misuse of antibiotics, procalcitonin (PCT) and C-reactive protein (CRP) have been used as new approaches to identify different types of infection. Multiple databases were adopted to search relevant studies, and the articles that satisfied the inclusion criteria were included. Meta-analyses were conducted with Review Manager 5.0, and to estimate the quality of each article, risk of bias was assessed. Eight articles satisfied the inclusion criteria. The concentrations of both PCT and CRP in patients with bacterial infection were higher than those with non-bacterial infection. Both PCT and CRP levels in patients with G− bacterial infection were higher than in those with G+ bacterial infection and fungus infection. In the G+ bacterial... |

| This study investigated factors that affect participation behavior of limited resource farmers (LRF) in Conservation Reserve Program (CRP) in Alabama. A binary logit model was employed to analyze data obtained from 611 respondents. Results indicated that males, part-time occupation, total acres, participation in non-conservation related programs, direct method of receiving CRP information, and respondents' interest in receiving CRP information, were strong predictors of participation in the CRP. Key words: Limited resource, CRP, minorities, participation behavior |

| Conservation reserve program (CRP) payments amount to several billion dollars annually. Payments are allocated to both remove land from production and to help farmers pay for conservation improvements. However, research examining whether farmers increase their utility with CRPs is limited. This paper uses simulation analysis and certainty equivalents to compare farming income to payments under the CRP. Farming income is a combination of crop production and government payments as specified in the 2002 Farm Bill. This analysis focuses on farms in three different counties in Kentucky. Results indicate that CRPs are good choices for many farmers. |

| The Conservation Reserve Program (CRP) is the largest land retirement program ever operated in the US. Since its inception in 1985, many researchers have studied the impacts of this program; however, only a few have analyzed how the CRP affects surrounding non–enrolled parcels. In this research I examine how the CRP may affect the conversion of non–cropped land to agriculture, a phenomenon referred to as “slippage” in the literature, and specifically addressed by Wu (2000) and Roberts and Bucholtz (2005). Building on these earlier studies, I empirically model slippage using data derived from satellite imagery that provides information on land cover changes between 1992 and 2001. The study area consists of 1,053 counties located in the Northern Plains, Corn... |

| The Conservation Reserve Program (CRP) was created in the 1985 Farm Bill as a program to remove highly erodible and environmentally sensitive land from agricultural production for 10-15 years. Originally viewed as a supply control program it rapidly evolved into a program that met many environmental objectives. In 2007 SD had 729,397 acres of CRP contracts expired, which was nearly 47% of the 1.56 million acres enrolled. The policy environment in late 2006 and most of 2007 consisted of CRP program offers for renewals or extensions (2-5 years) of many CRP contracts against a backdrop of escalating crop prices and economic incentives to return expiring contract acres to agricultural production. Overall there was a net reduction of 263.7 thousand acres (17%)... |

| How might increases in commodity prices, along with the acreage reduction mandated in the 2008 Farm Act, impact the Conservation Reserve Program (CRP)? Modeling Strategy The Likely To Bid (LTB) model “restarts” the CRP from scratch. Uses National Resources Inventory data to find parcels “likely” to offer acreage to the CRP Policy scenarios We consider several scenarios, both with and without increases in CRP rental rates. Continuation of current prices, which are well above prices prevalent when most CRP contracts were enrolled Predicted prices due to an increase in biofuels production to 15 billion gallons Expectation that summer 2008 prices will be the norm Findings Continuation of current, relatively high commodity prices would have noticeable... |
