Breeding can result in more output per unit of inputs as well as improved quality of outputs. A genetic-based technical change component is introduced into the Malmquist index, and productivity growth due to genetic and nongenetic factors is estimated for Icelandic dairy farms with quality...

We introduce genetic-based technical change into a Malmquist productivity index and measure the growth in productivity caused by bovine breeding. Because breeding is likely to affect milk quality, we adjust milk quantities for quality differences. We use panel data on Icelandic dairy farms from...
