The paper presents empirical analysis of a panel of countries to estimate an agricultural production function using a measure of capital in agriculture absent from most studies. The authors employ a heterogeneous technology framework where implemented technology is chosen jointly with inputs to...

Investments in technology have yielded large gains for agriculture, and the benefits have been passed on to consumers in the form of lower prices. Thus history justifies public spending on agricultural research.A comprehensive examination of data from many countries shows that in 1967-92, 81...

Asia's green revolution in rice was transformational and improved the lives of millions of poor households. Rice has become an increasingly important part of African diets and imports of rice have grown. Agronomists point out that large areas in Africa are well suited for rice and are encouraged...

This study develops a conceptual framework for analysing the ways in which changes in the economic environment modify factor productivity. It focuses on the technology actually used in production — implemented technology — rather than the generation of technology. Implementation reflects the...
