This paper develops a new measure of total factor productivity growth in agricultural Production which incorporates Bio Economic components effects. The new measure is called the Bio Economic-Oriented Total Factor Productivity (BTFP) index, and incorporates components of Bio Economic as liquids biofuels. BTFP measure changes in Bio Economic efficiency and can be decomposed into bio economy efficiency change (BEC), and Bio Economic technological change (BTC) components. An empirical analysis, involving 7 Central American countries-level during 1980-2007, is provided using DEA methods. The results show an annual growth in bio economy total factor bio economy productivity growth of 1.1 percent, with bio economy efficiency change (or bio economy catch-up) contributing 0.03 percent per year and bio economy technical change (or bio ethanol frontier-shift) providing 0.09 percent.
