We look at privatization in a general equilibrium model of a small, tariff-distorted, open economy. There is a differentiated good produced by both private and public sector enterprises. A reduction in government production in order to cut losses from such production raises the returns to...

Does competitive pressure foster innovation? In addressing this important question, prior studies ignored a distinction between discrete innovation aiming at entirely new technology and continuous improvement consisting of numerous incremental improvements and modifications made upon the...
