Technical efficiency, herd size, and exit intentions in U.S. dairy farms

Abstract

The U.S. dairy industry has seen major restructuring in recent decades. A sharp decline in the number of U.S. dairy farms and an increase in average herd sizes have accompanied exits, which have been concentrated among smaller herds. Given that more productive farms are better positioned to increase operation size and to continue operation, we hypothesize that the more technically efficient farms are better able to expand and also have stronger incentives to continue production. Using data from the USDA's 2010 ARMS Phase III, Dairy Production Practices and Costs and Returns Report, we estimate technical efficiency using stochastic production frontier analysis with endogenous inputs. The efficiency estimate is then incorporated into the analysis of exit intention and herd size. The results confirm our hypotheses that smaller and less efficient farms are more likely to exit and that more efficient dairy farms tend to expand herd size. Moreover, farms without successors but with older and more educated operators are more likely to exit. JEL classifications: D2, J2, Q12

Feed use intensification and technical efficiency of dairy farms in New Zealand

“…Previous studies have noted that farm efficiency differs by region due to differences in soil quality, geographical climate, attitude and farming practices (Kompas and Che ; Dong et al . ). A recent study by Jiang and Sharp () found that the mean technical efficiency for dairy farms in the South Island (81.96 per cent) was higher than that for farms in the North Island (69.52 per cent).…”

“…; Jiang and Sharp ; Dong et al . ) to identify a set of explanatory variables for technical inefficiency. Specifically, variables representing supplementary feed use intensification, farm size, herd size, farm location, milking frequency and shed type were selected and included in the inefficiency model.…”

Efficiency in wine grape production: comparing long‐established and newly developed regions of South Africa

“…All the statistical tests to determine the preferred model suggest that this simple model is an inadequate representation of these data when compared with more advanced models, which is common in this literature (see, for example, Dong et al. () and Seymour (). First, including the additional labor and viticulture variables in the OLS regression improved the F ‐statistic and increased the R 2 to 0.90, as four of the nine coefficients were significantly different from zero.…”

Effect of Herd size on the Productive, Reproductive, and Economic Efficiency of Holstein Dairy Cows

“…19.49) followed by medium (C.18.62) and large size group (C.18.01) in Karnal district. Additionally, Dong et al (2016) showed that larger size herds can continue in the production process than smaller size herds. As well, the profitability measures for larger size herds were superior to the comparable small size herds.…”
