Estimation of Commodity Specific Production Costs Using German Farm Accountancy Data AgEcon
Bahta, Sirak Teclemariam; Berner, Anja; Offermann, Frank.
A central problem in estimating per unit costs of production originates from the fact that most farms produce multiple outputs and standard farm-accounting data are only available at the whole-farm level. The seemingly unrelated regression (SUR) approach is used to estimate per unit production costs based on German farm accountancy data. Special emphasis is put on outlier detection prior to the estimation of production costs to increase the robustness of the results. Outlier observations are identified based on the Mahalanobis distance for each observation on the data set. It was observed that less negative cost coefficients are estimated after the exclusion of the outliers. The time series analysis of cost estimation based on SUR regression shows the...

The Structure Model Based Determinants of Capital Structure: A Seemingly Unrelated Regression Model AgEcon
Yan, Yan; Shi, Xiangdong; Barry, Peter J.; Paulson, Nicholas D.; Sherrick, Bruce J..
This study proposed a seemingly unrelated regression model to investigate the predicting capability of the structure model and test the capital structure theories. The model considered dynamic property of the structure model and characteristics of farm records. FBFM data are used in empirical analysis. The regression results provide new supportive evidence on capital theories.

Household Grocery Shopping Destination Allocation: Have Local Stores Caught on with the Rise of Local Foods? AgEcon
Zhou, Guzhen; Hu, Wuyang; Batte, Marvin T.; Woods, Timothy A.; Ernst, Stanley C..
Locavorism and the Local Food Movement have captured attention of consumers, production suppliers and academic researchers. Local food advocates emphasize the benefits of locally grown food from fresher to better tastes and to more energy efficient due to shorter transportation distance. However, limited studies have been done about household grocery purchase allocations in the awakening of local food, especially for individuals who stick with the “locavore” principle. Through a recent survey conducted in Ohio, this study found that mainstream food suppliers (national grocery chains or retailers) still claim most market shares, however, locally owned food stores and farmers’ markets are gaining popularity. The study also found that education attainment...
