The Relationship Between the Economic Surplus and Production Function Approaches for Estimating Ex-Post Returns to Agricultural Research
Provedor de dados: 31
Autores: Davis,   Jeffrey S.
The objective of this paper is to develop the conceptual linkage between the production function and economic surplus approaches used to evaluate the returns to agricultural research. First it is established that, for the Cobb-Douglas functional form generally used, an increase in research expenditure will result in a pivotal divergent shift in the supply function. It is then shown that the measure of this change in economic surplus is approximately the same as the value marginal product. Finally it is concluded that if the other possible types of supply shifts, that is, proportional divergent, parallel or convergent, are appropriate, then the production function approach will under-estimate the benefits and therefore rate of return to research expenditure.

A COMPARISON OF ALTERNATIVE PROCEDURES FOR CALCULATING THE RATE OF RETURN TO AGRICULTURAL RESEARCH USING THE PRODUCTION FUNCTION APPROACH
Provedor de dados: 31
Autores: Davis,   Jeffrey S.
The aim of this paper is to test whether the marginal internal rate of return (MIRR) to research and extension estimates are sensitive to the estimation procedure used to find them. To achieve this, a summary of the previously used estimation procedures is made. Following this a cross section aggregate production function estimate is developed for the U.S. in 1964. The parameter estimates from this model are used to calculate the MIRR's using the different estimation procedures.

A COMPARISON OF PROCEDURES FOR ESTIMATING RETURNS TO RESEARCH USING PRODUCTION FUNCTIONS
Provedor de dados: 31
Autores: Davis,   Jeffrey S.
The production function approach has been one of the two main ex-post procedures used to estimate the rate of return to agricultural research. A critical part of estimating the marginal internal rate of return (MIRR) is the procedure adopted to spread the benefits of research through time. Past studies using this approach have given only brief consideration to this computational procedure. The objective in this study was to review the different computational procedures used and, then, using cross-section production function estimates for U.S. agriculture, determine whether the MIRR estimates are sensitive to the computational procedure used. The results from this comparison indicate a large range in the estimates. The implication, then, is that careful...

THE INFLUENCE OF THE 1973 FEDERAL GOVERNMENT TAXATION CONCESSION REVISIONS ON AGRICULTURE
Provedor de dados: 31
Autores: Davis,   Jeffrey S.
In recent years there has been considerable discussion of many aspects of taxation policy, this note attempts to add to this discussion by taking a broader outlook than considering merely those concessions or policies which have been changed. This is done by, firstly, considering some theoretical implications of taxation concessions, and particularly the concept of a "neutral tax" policy. Secondly, by outlining the possible situations when concessions may be justified. Thirdly, by giving a brief summary of the previous taxation concessions, their aims, whether these aims fit into the conditions under two above and their actual effects. Finally, in light of the theoretical considerations summarized in section 2, a brief assessment is given of the impact of...
