Statistical methods are used to study relationships between research expenditures (adjusted for inflation) made from producer checkoff programs and soybean yields and net revenues in the United States for the years 1978 – 2007. Results presented are for yield and net revenue data and research expenditures for the entire United States. We find that research expenditures over the years 1994 to 2007 are responsible for a 0.95 bushel per acre per year increase in soybean yields. We calculate net producer revenues to be about $17 per acre higher than would have been the case without the soybean research checkoff expenditures. |

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. |

The Staggers Rail Act of 1980 granted railroads freedom to establish rates and enter into confidential contracts with grain shippers. Recent legislation (1986) required that certain contract terms be disclosed. This study shows rail rates in the Plains region commenced an upward trend after implementation of the disclosure policy. Results suggest contract disclosure and increased reliance on posted tariffs facilitated rate coordination within the oligopolistic railroad industry. |

To date, mixed demand systems have been all but ignored in empirical work. A possible reason for the scarcity of such applications is that one needs to know a priori which prices and quantities are endogenous in the mixed demand system. By using a directed acyclical graph (DAG), causal relationships among price and quantity variables are identified giving rise to a causally identified demand system (CIDS). A statistical comparison is made of the traditional Rotterdam model with a Rotterdam mixed demand system identified through the use of a DAG. In this analysis, the respective Rotterdam demand systems consist of five products: steak, ground beef, roast beef, pork, and chicken. |

For many decades, fresh fruits and vegetables enjoyed a reputation as the healthiest products full of essential vitamins, minerals, and other beneficial substances for a balanced diet. However, numerous recent food outbreaks associated with fresh produce have raised concerns on the mind of the consumer. Following an outbreak, consumers reduce their immediate consumption of the affected products. Even tough fresh fruits and vegetables have unique characteristics and flavors, consumers tend to substitute affected outbreak products with other fruits and vegetables. The potential impact of food borne illness on consumption has also a longer term impact, reducing consumption of the products over a period of several months after the outbreak. This paper used... |

The paper considers the use of directed acyclic graphs (DAGs), and their construction from observational data with PC-algorithm TETRAD II, in providing over-identifying restrictions on the innovations from a vector autoregression. Results from Sims’ 1986 model of the US economy are replicated and compared using these data-driven techniques. The directed graph results show Sims’ six-variable VAR is not rich enough to provide an unambiguous ordering at usual levels of statistical significance. A significance level in the neighborhood of 30 % is required to find a clear structural ordering. Although the DAG results are in agreement with Sims’ theory-based model for unemployment, differences are noted for the other five variables: income, money supply, price... |

Advanced methods that combine directed acyclic graphs with Bernanke structural vector autoregression models are applied to a monthly system of three U.S. soy-based markets: for soybeans upstream and for the two soybean co-products soy meal and soy oil further downstream. Analyses of the impulse-response function and forecast error variance decompositions provide updated estimates of market-elasticity parameters that drive these markets and updated policy-relevant information on how these monthly markets run and dynamically interact. Results characterize impacts on the three U.S. soy-based markets of increases in U.S. prices of soy meal and soybeans. |

Vector autoregression was utilized to investigate dynamic relationships existing between prices of purebred bulls and prices of slaughter steers, utility cows, feeder calves, and cow-calf pairs. Results suggest purebred bull prices respond most quickly to an increase in utility cow prices (proxy for slaughter bull prices). Feeder calf prices exhibited the most pronounced positive effect on the price of herd sires, with a lagged response which took over two years to build. |

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... |

Temporal relationships are investigated among fabricated cut prices, carcass value, and fed cattle prices. Also, linkages between fed cattle and wholesale beef prices are examined using vector autoregressive (VAR) techniques. Results, using daily prices over the 1980-85 period, suggested that fabricated cut prices and cattle prices are related to the imputed carcass value, carcass quote, and fed cattle prices. In addition, three fabricated cuts dominate as leading indicators of fed cattle prices of most fabricated cut prices. They are strip loin and bottom and top round prices. VAR models outperform the univariate and random-walk models of forecasting ability. |
