INTERPAKS, Examines the level of significance of extension services and the marginal contribution of extension services to increased agricultural production in Gujarat State (1976-77). In addition, the marginal contributions of extension services are compared for the high and low productivity areas of the state. Results of the regression analysis indicate that extension investment has played a significant role in increasing agricultural production only in the high productivity areas while in the low productivity areas it has played an insignificant and even negative role.

17 pages., Via online journal., This article provides new estimates of the marginal product of public agricultural research and extension on state agricultural productivity for the U.S., using updated data and definitions, and forecasts of future agricultural productivity growth by state. The underlying rationale for a number of important decisions that underlie the data used in cost‐return estimates for public agricultural research and extension are presented. The parameters of the state productivity model are estimated from a panel of contiguous U.S. 48 states from 1970 to 2004. Public research and extension are shown to be substitutes rather than complements. The econometric model of state agricultural TFP predicts growth rates of TFP for two‐thirds of states that is less than the past trend rate. The results and data indicate a real social rate of return to public investments in agricultural research of 67% and to agricultural extension of 100+%. The article concludes with guidance for TFP analyses in other countries.
