ANALYSIS OF DYNAMIC INTERRELATIONSHIPS BETWEEN TRANSPORTATION RATES AND GRAIN PRICES AgEcon
Yu, Tun-Hsiang (Edward); Bessler, David A.; Fuller, Stephen W..
Transportation rates are vital components in the structure of U.S. grain exports. In this paper we study the dynamic properties of corn and soybean prices, and barge, rail and ocean shipping rates using time series analysis on monthly 1992-2001 data. Using Error Correction Model and Directed Acyclic Graphs, we capture the interconnectivity between the transportation rates and grain prices at selected domestic and export markets. We find Illinois processor prices are important sources of price discovery for both corn and soybeans. Further, barge rates explain about 2-4% of the variation in grain prices while rail rates explain about 10-12% of the variation in corn and soybean prices.

Analyzing the Economics Values of An Alternative Preprocessing Facility in the Biomass Feedstocks - Biorefinery Supply Chain AgEcon
Yu, Tun-Hsiang (Edward); Larson, James A.; Gao, Yuan; English, Burton C..
It is generally believed that preprocessing procedure can reduce the transportation and storage costs of biomass feedstock for biofuel production by condensing the feedstock’s size. However, the capital costs of preprocessing facilities could be significant in the feedstock logistics system. Applying a GIS and mixed-integer mathematical programming model, this study evaluates the economic values of a preprocessing technology, stretch‐wrap baling, in the biomass feedstock supply chain for a potential commercial-scale switchgrass biorefinery in East Tennessee. Preliminary results suggest that the stretch-wrap baling equipment outperforms the conventional hay harvest methods in terms of total delivered costs. Although the densification process involves...

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...

Cointegration and Causality Analysis of World Vegetable Oil and Crude Oil Prices AgEcon
Yu, Tun-Hsiang (Edward); Bessler, David A.; Fuller, Stephen W..
Because of the recent soaring petroleum price and growing environmental concerns, biodiesel has become an important alternative fuel. Biodiesel is the mono alky esters made from a vegetable oil, such as soybean or rapeseed oil, or sometimes from animal fats. The escalation in world petroleum price has stimulated the demand for biodiesel, which consequently expanded the use of vegetable oils. This paper investigates the long-run interdependence between major edible oil prices and examines the dynamic relationship between vegetable and crude oil prices. The data consists of 378 weekly observations extending from the first week of January in 1999 to the fourth week of March in 2006. We apply time-series analytical mechanisms and directed acyclic graphs...

Evaluating the Production and Price Impacts of Biotechnology Application in Crop Markets AgEcon
Brookes, Graham; Yu, Tun-Hsiang (Edward); Tokgoz, Simla; Elobeid, Amani E..
Biotechnology crop traits have been applied on a widespread commercial global basis since 1996, making it the most rapidly adopted crop technology in agriculture. The primary biotechnologies used have included technology delivering herbicide tolerance and insect resistance for crops, such as corn, soybeans, cotton, and canola. This technology has provided farmers with productivity improvements through a combination of yield improvements and cost reductions. Thus, this technology has had an impact on prices of cereals and oilseeds (and their derivatives) both in countries where biotech traits were applied and in the global market. Realizing the surging significance of biotechnology application in global crop markets, this study first summarizes the...

Impact of Biofuel Industry Expansion on Grain Utilization and Distribution: Preliminary Results of Iowa Grain and Biofuel Survey AgEcon
Yu, Tun-Hsiang (Edward); Hart, Chad E..
This paper examines the impact of biofuel expansion on grain utilization and distribution at the state and cropping district level as most of grain producers and handlers are directly influenced by the local changes. We conducted a survey to understand the utilization and flows of corn, ethanol and its co-products, such as dried distillers grains (DDG) in Iowa. Results suggest that the rapidly expanding ethanol industry has a significant impact on corn utilization in Iowa. Comparing to the earlier survey results, ethanol plants drew a considerable amount of corn away from traditional destination markets, such as feeders or export markets. A major portion of corn supplies came from in-state sources, while the sales of Iowa ethanol and DDG were dominated by...

Land Allocation Effects of the Global Ethanol Surge: Predictions from the International FAPRI Model AgEcon
Fabiosa, Jacinto F.; Beghin, John C.; Dong, Fengxia; Elobeid, Amani E.; Tokgoz, Simla; Yu, Tun-Hsiang (Edward).
We quantify the emergence of biofuel markets and its impact on U.S. and world agriculture for the coming decade using the multi-market, multi-commodity international FAPRI (Food and Agricultural Policy Research Institute) model. The model incorporates the trade-offs between biofuel, feed, and food production and consumption and international feedback effects of the emergence through world commodity prices and trade. We examine land allocation by type of crop, and pasture use for countries growing feedstock for ethanol (corn, sorghum, wheat, sugarcane, and other grains) and major crops competing with feedstock for land resources such as oilseeds. We shock the model with exogenous changes in ethanol demand, first in the United States, then in Brazil, China,...

LOCK CONGESTION AND ITS IMPACT ON GRAIN BARGE RATES ON THE UPPER MISSISSIPPI RIVER AgEcon
Yu, Tun-Hsiang (Edward); Fuller, Stephen W.; Bessler, David A..
An anticipated increase in lock delays on the upper Mississippi River has generated concern about its future navigational efficiency. The objective of this paper is to identify selected factors affecting lock delay on the River's busiest locks and to examine the impact of lock delay on grain barge rates. Results show that lock unavailability, traffic level, and delay at nearby locks affect lock delay. Further, barge rates are affected by lock delay, however, the impact is modest.

Long-Term and Global Tradeoffs between Bio-Energy, Feed, and Food AgEcon
Tokgoz, Simla; Elobeid, Amani E.; Fabiosa, Jacinto F.; Hayes, Dermot J.; Babcock, Bruce A.; Yu, Tun-Hsiang (Edward); Dong, Fengxia; Hart, Chad E.; Beghin, John C..
Projections of U.S. ethanol production and its impacts on planted acreage, crop prices, livestock production and prices, trade, and retail food costs are presented under the assumption that current tax credits and trade policies are maintained. The projections were made using a multi-product, multi-country deterministic partial equilibrium model. The impacts of higher oil prices, a drought combined with an ethanol mandate, and removal of land from the Conservation Reserve Program (CRP) relative to baseline projections are also presented. The results indicate that expanded U.S. ethanol production will cause long-run crop prices to increase. In response to higher feed costs, livestock farmgate prices will increase enough to cover the feed cost increases....

Mitigating Land Use Changes From Biofuel Expansion: An Assessment of Biofuel Feedstock Yield Potential in APEC Economies AgEcon
Elobeid, Amani E.; Tokgoz, Simla; Yu, Tun-Hsiang (Edward).
The emerging biofuel sector has drawn great interest as an alternative source of fuel for transportation. The expansion of biofuels greatly impacts world agricultural markets, since currently, the primary feedstocks for ethanol and biodiesel production are field crops and their derived products. There is great interest in the potential of countries to expand their biofuel sectors through increased production of feedstocks. The long-term potential for developing first-generation biofuels in many countries depends on a large and constant supply of feedstocks. This may be achieved in two ways: land extensification and/or land intensification. However, expansion of land area comes with a number of environmental challenges highlighted by the recent debate on...
