Resumen
Descripción
Georgia agricultural production continues on an increasing trend and reached a historical high in 2006. Increases in output have been accompanied by relatively lower levels of input increases. The Tornqvist productivity index indicates an average annual productivity increase of 3.0% during 1960-2006. Productivity increases explain how the Georgia agricultural economy is expanding during a period when farm acreage and the number of farms are declining. An alternative to the Tornqvist productivity index is the Bennet-Bowley productivity indicator. A feature of the Bennet-Bowley indicator is that it is a component of normalized profit change. Profit change can be decomposed into a price change component, as well as a productivity component. Declining output prices relative to input prices during 1960-2006 were not favorable for increased profitability. Results show that Georgia farm profit increased from 1960-2006 due to increased agricultural productivity.
