| Title: | The Impact of recombinant bovine Somatotropin on Dairy Farm Profits: A Switching Regression Analysis |
| Authors: | Tauer, Loren W. |
| Issue Date: | 2003-09 |

| Abstract: | Production and profit impacts from the use of recombinant Bovine
Somatotropin (rbST) on dairy farms were estimated using switching regression, with
separate regressions for rbST-using farms and non-rbST-using farms. To correct for
potential self-selection bias, a probit adoption function was estimated and used to
correct the error term in each regression equation. Farmers who use rbST were found
to have more formal education and have larger dairy herds, but age was not a
significant determining factor in adoption. RbST was estimated to increase milk
production per cow even when correcting for the fact that rbST users would have
higher milk production per cow without the use of rbST. However, that greater
production per cow from rbST use did not translate into an estimated impact on
profits per cow. |
