Trade-adjusted measures of productivity increases in US hog production
The average dressed weight for barrows and gilts slaughtered in the United States has increased 23% since 1977, from an annual average of 163lbs to 201lbs in 2010. This measure of pork production includes pork produced from US born and raised hogs as well as hogs imported from Canada. This paper addresses technological change in US born and raised pork production. Since pork produced from Canadian hogs could distort estimates of technological improvement and other variables describing changes in US born and raised pork production, a method of adjusting production data series for the portion of US pork production that comes from foreign-born hogs is developed. The resulting data are used to estimate the rate of change in average dressed weight, assumed to be due to technical change in the US swine herd.
