| 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. |

| 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,... |

| 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,... |
