Agricultural productivity in 41 Sub-Saharan Africa (SSA) countries from 1960 to 1999 is examined by estimating a semi-nonparametric Fourier production frontier. Over the four decades the estimated rate of productivity change was 0.83% per year, although the average rate from 1985-99 was a strong...

In this paper we propose an empirical model to decompose the evolution of the agricultural GDP share of Taiwan into three components: price changes, factor endowment changes and technological change. The full sample period is 1967 to 1997. The data were first tested to assess whether the time...

Young (1995) estimated Total Factor Productivity (TFP) growth for Hong Kong, Taiwan, Singapore and South Korea. He reported moderate growth rates for these four regions. This means that rapid growth of GDP in these four economies is due mainly to fast increase of inputs. Young (2000) also...

This paper examines changes in agricultural productivity in18 developing countries over the period 1961-1985. We use the nonparametric, output- based Mamquist index to examine whether the results from such approach confirm results from other methods that have indicated declining agricultural...

The present paper explores why farmers are taxed in poor countries and subsidized in rich countries. Using the economic theory of contests to come to an understanding of the incentives for agricultural protectionism, we first sketch a framework for an excludable and rivalrous rent. We then apply...

This paper introduces a dynamic model of productivity measurement based on recent endogenous growth theories. The model presented in this study is based on dynamic duality theory and incorporate public goods (public capital and R&D) as external factors to the firms. It also rationalizes the...

This study uses the quantity-based Allais-Debreu measure of loss to measure the waste, in output or resources, induced by interventions in the agricultural sector in 18 developing countries.

In this paper we adapt a partial equilibrium approach of Allais and Diewert to measure the efficiency loss in the producing sector due to quotas. The measure of waste is the additional profits available due to reallocation subject to constraints that the welfare of persons and firms outside the...

The objective of this paper is to present Hickssian general equilibrium approaches to productivity measurement in the presence of market failure.

The issue considered here is the retail pricing of patented crop traits such as Roundup Ready herbicide resistance or Bt insect resistance. Our concern is not with the price of the seeds in which the traits are embodied, but rather with the implicit or explicit price for the traits themselves....
