Analysis of the Soybean-to-Corn Price Ratio and its Impact on Farmers' Planting Decision-Making in Indiana 31
Ubilava, David.
In Indiana agricultural land is used mostly for corn and soybean harvesting. Rotated corn is a common practice, but in recent years, essentially due to the "ethanol boom" and increased profitability of corn production, many farmers have switched to continuous corn. Corn price increase affects the soybean-to-corn (STC) ratio, however, it is hypothesized that over time market effects will be felt, and return the ratio to its stable range. The threshold autoregressive model is used to analyze the monthly time series of STC ratio in Indiana. Results suggest that exogenous shocks will not have permanent effect on the STC price ratio, but will require, however, a reasonably long time to die out.

DIFFERENCES IN U.S. CONSUMER PREFERENCES FOR CERTIFIED PORK CHOPS WHEN FACING BRANDED VS. NON-BRANDED CHOICES 31
Ubilava, David; Foster, Kenneth A.; Lusk, Jayson L.; Nilsson, Tomas K.H..
Consumers' preferences for credence attributes of a product may differ from each other, when facing the choices between branded and/or non-branded products. We test this hypothesis with conditional and mixed logit regression using data obtained by choice experiment surveys. The results suggest that, on average, consumers are willing to pay more for a certification attribute when the product is branded. Additionally, greater variation in consumer willingness-to-pay is observed in the non-branded case. This latter characteristic of the results may represent the increased uncertainty some consumers internalize concerning quality consistency when brand information is not provided. These results have interesting implications for producers, processors,...

EFFECTS OF FIRM-SPECIFIC FACTORS ON R&D EXPENDITURES OF AGRIBUSINESS COMPANIES 31
Roucan-Kane, Maud; Ubilava, David; Xu, Pei.
The objective of this paper is to determine how the firm's infrastructure, the financial characteristics of a company (net income, sales), and the organizational structure (number of acquisitions, age of establishment of the firm) affect R&D investments in the agricultural sector. We use data for companies under the SIC codes for agricultural chemicals, and crop planning and protection. The results based on analysis of 69 observations of 12 firms revealed that firm's financial and organizational infrastructure does affect its R&D expenditures. Older and larger firms tend to spend more on R&D. During the last 17 years the R&D expenditures with respect to the sales of the company have been reduced. Finally, contrary to the expectations,...

Nonlinearities in the World Vegetable Oil Price System: El Nino Effects 31
Ubilava, David; Holt, Matthew T..
In this research we estimate the effect of El Nino Southern Oscillation (ENSO) over time on market dynamics for eight major vegetable oil prices. We estimate a system for vegetable oil prices by using a smooth transition vector error correction model (STVECM) to analyze impacts of ENSO events on production, and, more interestingly, their asymmetric nature. The results of estimated Exponential STVECM and Quadratic STAR models, respectively for the system of oil price equations and the ENSO variable regressions, suggest a smooth transition between ENSO regimes, and provide a better overall fit to the data than do linear models. Effects of the ENSO shock are analyzed using generalized impulse-response functions (GIRFs). The non-linear nature of these shocks...

Targeting Consumers by Store - The Basis of Increased Sales with Less Advertising 31
Ubilava, David; Foster, Kenneth A..
Conditional Logit approach was used to analyze the Choice Experiment data obtained from the grocery stores and supermarket of Tbilisi, Georgia. Results show that customers' preferences for selected pork attributes in different stores are not the same. So, targeting customers by store can be beneficial marketing tool for pork suppliers.

The Effect of the El Nino Southern Oscillation on U.S. Corn Production and Downside Risk 31
Tack, Jesse B.; Ubilava, David.
El Nino Southern Oscillation (ENSO) teleconnections imply anomalous weather conditions around the globe, causing yield shortages, price changes, and even civil unrests. Extreme ENSO events may cause catastrophic damages to crop yields, thus amplifying downside risk for producers. This study presents a framework for quantifying the effects of climate on crop yield distributions. An empirical application provides estimates of the effect that ENSO events have on the means of U.S. county-level corn yield distributions, as well as the probabilities of catastrophic crop loss. Our findings demonstrate that ENSO events strongly influence these probabilities systematically over large production regions, which has important implications for research and policy...

The ENSO Impact on Predicting World Cocoa Prices 31
Ubilava, David; Helmers, Claes Gustav.
Cocoa beans are produced in equatorial and sub-equatorial regions of West Africa, Southeast Asia and South America. These are also the regions most affected by El Nino Southern Oscillation (ENSO) -- a climatic anomaly affecting temperature and precipitation in many parts of the world. Thus, ENSO, has a potential of affecting cocoa production and, subsequently, prices on the world market. This study investigates the benefits of using a measure of ENSO variable in world cocoa price forecasting through the application of a smooth transition autoregression (STAR) modeling framework to monthly data to examine potentially nonlinear dynamics of ENSO and cocoa prices. The results indicate that the nonlinear models appear to outperform linear models in terms of...

The SURE Program and Its Interaction with Other Federal Farm Programs 31
Ubilava, David; Barnett, Barry J.; Coble, Keith H.; Harri, Ardian.
We investigate potential effects of the Supplemental Revenue Assistance Payments (SURE) program introduced in the 2008 Farm Bill. Results suggest little impact on optimal crop insurance purchase decisions, though the SURE program does seem to provide an incentive for mid-level insurance coverage. For producers in the price counter-cyclical payment (PCCP) program, SURE payments are actually higher (lower) when commodity prices are high (low). This is not the case for producers in the Average Crop Revenue Election (ACRE) program.
