This paper investigates the total factor productivity (TFP) performance of NWFP agriculture crop subsector from 1970 to 2004. It identifies the sources of growth of TFP growth and assesses TFP growth changes in agriculture crop sub-sector. Data envelopment analysis (DEA) approach is used to estimate the changes in the production frontier. The Malmquist productivity index has decomposed total fa...

We characterise the following equilibria: Persistent asymmetry where nobody adopts, Leapfrogging where low quality firms adopt, Forging ahead where high quality firms adopt, and Catching up where everybody adopts. We study th...
