The 2006/07 Iowa Grain and Biofuel Flow Study: A Survey Report AgEcon
Yu, Tun-Hsiang (Edward); Hart, Chad E..
This report is divided into two sections. The first part reports the statewide results for each of five surveyed groups: Iowa grain marketers, Iowa grain handlers, Iowa corn processors, Iowa soybean processors, and Iowa biodiesel producers. The state-level results provide a general idea of the grain and biofuel flows that occurred and the transportation that was utilized in the biofuel-boom era. In order to gain further insights into the regional level data, we present the survey results of grain marketers and handlers in each crop reporting district (CRD) in the second part of the report.

Using a Farmer's Beta for Improved Estimation of Actual Production History (APH) Yields AgEcon
Carriquiry, Miguel A.; Babcock, Bruce A.; Hart, Chad E..
The effect of sampling error in estimation of farmers' mean yields for crop insurance purposes is explored using farm-level corn yield data in Iowa from 1990 to 2000 and Monte Carlo simulations. We find that sampling error combined with nonlinearities in the insurance indemnity function will result in empirically estimated crop insurance rates that exceed actuarially fair values by between 2 and 16 percent, depending on the coverage level and the number of observations used to estimate mean yields. Accounting for the adverse selection caused by sampling error results in crop insurance rates that will exceed fair values by between 42 and 127 percent. We propose a new estimator for mean yields based on a common decomposition of farm yields into systemic and...

INSURING EGGS IN BASKETS AgEcon
Hart, Chad E.; Hayes, Dermot J.; Babcock, Bruce A..
The vast majority of crop and revenue insurance policies sold in the United States are single-crop policies that insure against low yields or low revenues for each crop grown on a particular farm. This practice of insuring one crop at a time runs counter to the traditional risk management practice of diversifying across several enterprises to avoid putting all of ones eggs in a single basket. This paper examines the construction of whole-farm crop revenue insurance programs to include livestock. The whole-farm insurance product covers crop revenues from corn and soybeans and livestock revenues from hog production. The results show that at coverage levels of 95 percent or lower, the fair insurance premiums for this product on a well-diversified Iowa hog...

AN ANALYSIS OF THE PROPOSED DOHA ROUND MODALITIES AgEcon
Babcock, Bruce A.; Fabiosa, Jacinto F.; Matthey, Holger; Isik, Murat; Tokgoz, Simla; Elobeid, Amani E.; Hart, Chad E.; Full, Frank.
The Uruguay Round Agreement on Agriculture (URAA) provided a continuing mandate for progressive reforms to liberalize world agricultural markets. A new round of negotiation was put into motion in early 2000 and later formalized in what is now called the Doha Round. The Doha Round negotiation follows the same principle laid out in the URAA, with the introduction of three reform anchors: market access, export competition, and reduction of domestic support. This paper specifies the new schedule of commitments for each member country under the proposed modalities and assesses the potential market impacts of these changes for world agricultural markets. We specifically focus on grains, oilseeds, sugar, cotton, livestock, poultry, and dairy markets.

RETHINKING AGRICULTURAL DOMESTIC SUPPORT UNDER THE WORLD TRADE ORGANIZATION AgEcon
Beghin, John C.; Hart, Chad E..
This paper focuses on the third pillar of the Uruguay Round Agreement on Agriculture (URAA) of the World Trade Organization (WTO), the discipline of agricultural domestic support. The paper examines the current definition of agricultural domestic support used by the WTO, focusing on the Aggregate Measure of Support (AMS) and other forms of support that are less to least distorting (Blue and Green Box payments). The analysis looks at the recent experience of four member states (the United States, the European Union, Japan, and Brazil). The structure of recent support varies considerably by country. Some countries, notably the United States, have strategically used the de minimis exemption to deflate their support figures substantially in order to remain...

Rankings of Risk Management Strategies Combining Crop Insurance Products and Marketing Positions AgEcon
Hart, Chad E.; Babcock, Bruce A..
Farmers can choose from a wide selection of crop insurance products and marketing strategies. Combinations of these risk management tools have varying effects on the user's risk environment. Nine risk management strategies are ranked for their impacts on average returns, certainty equivalent returns, and risk premiums. The analysis is conducted using historical price and yield data for 1976 to 1999 in five Iowa counties. The results show the benefits of crop insurance in reducing revenue risk. Also, given that the producer will forward contract some of his or her crop, the combination of E-Markets' Decision Rules for Contracts (DRC) pricing tool and Crop Revenue Coverage (CRC) crop insurance receives the highest ranking.

Using a Farmer's Beta for Improved Estimation of Expected Yields AgEcon
Carriquiry, Miguel A.; Babcock, Bruce A.; Hart, Chad E..
Effects of sampling error in estimation of farmers’ mean yields for crop insurance purposes and their implications for actuarial soundness are explored using farm-level corn yield data in Iowa. Results indicate that sampling error, combined with nonlinearities in the indemnity function, leads to empirically estimated insurance rates that exceed actuarially fair values. The difference depends on the coverage level, the number of observations used, and the participation strategy followed by farmers. A new estimator for mean yields based on the decomposition of farm yields into systemic and idiosyncratic components is proposed, which could lead to improved rate-making and reduce adverse selection.

CROP INSURANCE RATES AND THE LAWS OF PROBABILITY AgEcon
Babcock, Bruce A.; Hart, Chad E.; Hayes, Dermot J..
Increased crop insurance subsidies have increased the demand for insurance at coverage levels higher than the traditional level of 65 percent. Premium rates for higher levels of yield insurance under the Federal Actual Production History (APH) program equal the premium rate at the 65 percent coverage level multiplied by a rate relativity factor that varies by coverage level but not by crop or region. In this paper, we examine the consistency of these constant rate relativity factors with the laws of probability by determining the maximum 65 percent premium rate that is consistent with a well-defined yield distribution. We find that more than 50 percent of U.S. counties have premium rates for corn, soybeans, and wheat that are not consistent with the laws...

Scott; Adams, Gary M.; Willott, Brian; Madison, Daniel; Meyer, Seth D.; Kruse, John R..
The Food and Agricultural Policy Research Institute (FAPRI) prepares a preliminary agricultural outlook on world agricultural production, consumption, and trade every fall. This is followed by an outside review, re-evaluation of projections, and completion of the final baseline in January. The FAPRI 2000 World Agricultural Outlook presents these final projections for world agricultural markets. A companion volume, the FAPRI 2000 U.S. Agricultural Outlook, presents the U.S. component of the baseline. FAPRI projections assume average weather patterns worldwide, existing policy, and policy commitments under current trade agreements. FAPRI projections do not include conjectures on potential policy changes, such as those resulting from the likely eastward...

Influence of the Premium Subsidy on Farmers' Crop Insurance Coverage Decisions AgEcon
Babcock, Bruce A.; Hart, Chad E..
The Agricultural Risk Protection Act greatly increased the expected marginal net benefit of farmers buying high-coverage crop insurance policies by coupling premium subsidies to coverage level. This policy change, combined with cross-sectional variations in expected marginal net benefits of high-coverage policies, is used to estimate the role that premium subsidies play in farmers' crop insurance decisions. We use county data for corn, soybeans, and wheat to estimate regression equations that are then used to obtain insight into two policy scenarios. We first estimate that eventual adoption of actuarially fair incremental premiums, combined with current coupled subsidies, would increase farmers' purchase of high-coverage policies by almost 400 percent...

Biofuels: Potential Production Capacity, Effects on Grain and Livestock Sectors, and Implications for Food Prices and Consumers AgEcon
Hayes, Dermot J.; Babcock, Bruce A.; Fabiosa, Jacinto F.; Tokgoz, Simla; Elobeid, Amani E.; Yu, Tun-Hsiang (Edward); Dong, Fengxia; Hart, Chad E.; Chavez, Eddie C.; Pan, Suwen; Carriquiry, Miguel A.; Dumortier, Jerome.
We examined four evolution paths of the biofuel sector using a partial equilibrium world agricultural sector model in CARD that includes the new RFS in the 2007 EISA, a two-way relationship between fossil energy and biofuel markets, and a new trend toward corn oil extraction in ethanol plants. At one extreme, one scenario eliminates all support to the biofuel sector when the energy price is low, while the other extreme assumes no distribution bottleneck in ethanol demand growth when the energy price is high. The third scenario considers a pure market force driving ethanol demand growth because of the high energy price, while the last is a policy-induced shock with removal of the biofuel tax credit when the energy price is high. Standard results hold where...

Option Pricing on Renewable Commodity Markets AgEcon
Jin, Na; Lence, Sergio H.; Hart, Chad E.; Hayes, Dermot J..
Options markets on agricultural commodities with maturities that exceed 13 months seldom trade. Our hypothesis is that this market failure is due to the absence of an accurate option pricing model for commodities where mean reversion can be expected. Standard option pricing models assume proportionality between price variance and time to maturity. This proportionality is not a valid assumption for commodities where supply response works to bring prices back to production costs. The model suggests that traditional option pricing models will overprice long-term options on these markets.

Farm-Level Analysis of Risk Management Proposals AgEcon
Babcock, Bruce A.; Hart, Chad E.; Adams, Gary M.; Westhoff, Patrick C..
This paper presents a detailed report of the representative farm analysis (summarized in FAPRI Policy Working Paper #01-00). At the request of several members of the Committee on Agriculture, Nutrition, and Forestry of the U.S. Senate, we have continued to analyze the impacts of the Farmers' Risk Management Act of 1999 (S. 1666) and the Risk Management for the 21st Century Act (S. 1580). Earlier analysis reported in FAPRI Policy Working Paper #04-99 concentrated on the aggregate net farm income and government outlay impacts. The representative farm analysis is conducted for several types of farms, including both irrigated and non-irrigated cotton farms in Tom Green County, Texas; dryland wheat farms in Morton County, North Dakota and Sumner County, Kansas;...

CAP Reform and the WTO: Potential Impacts on EU Agriculture AgEcon
Binfield, Julian C.R.; Donnellan, Trevor; Hanrahan, Kevin F.; Hart, Chad E.; Westhoff, Patrick C..
In 2003 an agreement was finalized to instigate arguably the most significant reform of the European Union's (EU) Common Agricultural Policy (CAP) since its inception. In the Luxembourg Agreement many of the direct payments that have been linked to production are decoupled and instead provided in the form of a land-based payment. The reforms did not include any significant changes to either EU border support or the ability of the EU to utilize export subsidies that have been widely criticized by other nations. Even though the reforms do not directly address trade in agricultural products it is argued that World Trade Organization (WTO) concerns played a significant role in the designs of the reforms. In this paper an analysis of the Luxembourg reforms and...
