The Malmquist index has become extensively used in international comparisons of agricultural productivity since it does not require prices for its estimation, which are normally not available. However, the DEA approach used to estimate this index still uses implicit price information. This...

This paper addresses the issue of the shadow price of environmental bads treated as an undesirable output (normal input) with weak (strong) disposability in a two-stage estimation. Nebraska agriculture sector time series data used is spread over 1936-94. Results indicate the difference in the...

The biological nature of agricultural production processes induce a higher degree ofuncertainty surrounding the economic performance of farm enterprises. This has contributedto the development and acceptance of forms of public intervention aimed at reducing incomevariability that have no...

Researchers should be wary of the expectations framework and optimization method employed when drawing conclusions about the likely production behavior of farmers The article compares the predictive accuracy of two expectational schemes, supply-based expectations (SBE) and adaptive expectations...

This article investigates the possibilities of including policy choices directly into a sector model that simulates an economic equilibrium It uses a mathematical programming framework because these models have wide applicability in agricultural sector analysis The objective function is...

This research demonstrates the need and the procedure for testing sector programming models It compares the model estimates of endogenous variables to carefully selected base period parameters It uses an operational, static, deterministic, and highly aggregate programming model of Philippine...

A basic model is presented as an expansion of the general location model for optimal organization of an industry operating in spatial markets. Complications are introduced into the model: variations in raw product costs, inventory and carryover (considerations, and multiproduct firms. Recent...
