In this paper we examine levels and trends in agricultural output and productivity in 93 developed and developing countries that account for a major portion of the world population and agricultural output. We make use of data drawn from the Food and Agriculture Organization of the United Nations...

The estimated parameters of output distance functions frequently violate the monotonicity, quasiconvexity and convexity constraints implied by economic theory, leading to estimated elasticities and shadow prices that are incorrectly signed, and ultimately to perverse conclusions concerning the...

The materials balance condition is a fundamental adding up condition, which essentially says that �what goes in must come out�. In this paper we argue that a number of the recently developed methods of incorporating pollution measures into standard productive efficiency models are...

In this paper we investigate the effect of the introduction of incentive regulation upon the total factor productivity (TFP) growth of electricity generation companies in the United States, using sample data on 61 firms observed over a 13-year period from 1986 to 1998. Empirical estimates of TFP...

Various government-owned businesses provide water supply services to Australian residents. With the advent of recent competition and regulatory reforms in infrastructure industries in Australia, more and more of these businesses are now facing new types of incentive-based regulatory regimes....

Information on the economies of scope (or cost complementarities) between two or more output variables is traditionally obtained from the second derivative properties of an econometrically estimated multi-output cost function. However, in some instances the econometric estimation of a cost...
