This paper presents (1) a conceptual framework for structural change when farms may be multiproduct or specialized and (2) an econometrics of causes of structural and total factor productivity (TFP) change for U.S. agriculture. Farm size, farm specialization, and part-time farming are the...

This paper provides a basis for both the base case projections and an important policy simulation dealing with the diffusion of biotechlogy to developing countries

This paper reviews econommic studies of rice research programs and attempts to identify the contributions of rice varietal improvement to changes in rice productivity. I also report some new work specifically addressed to the contributions of genetic resources to the production of rice varieties.

This paper tests whether structural change in US agriculture is an important channel to TFP growth and evaluate the relative impcat of (i) public research and education policies, (ii) private R&D and market forces, and (iii) government farm programs on structural change.

We partnered with a micro-lender in Mali to randomize credit offers at the village level. Then, in no-loan control villages, we gave cash grants to randomly selected households. These grants led to higher agricultural investments and profits, thus showing that liquidity constraints bind with...

The investment decisions of small-scale farmers in developing countries are conditioned by their financial environment. Binding credit market constraints and incomplete insurance can reduce investment in activities with high expected profits. We conducted several experiments in northern Ghana in...

This paper examines the apparent conflict between the classical assumption of a bargaining agricultural sector wage and the neo-classical assumption of a competitive wage in the context of a labour surplus developing economy. It concludes that the relatively inelastic supply of labour hours...

This paper present a model of the Green Revolution in India, in which the development and diffusion of HYVs, the expansion of irrigation and the expansion of multiple-cropping are treated as endogenous responses to more basic investments in agricultural technology and infrastructure, as well as...

This paper examines whether sharecroppers and fixed-rent tenants in the rice farms of South Asia are distinguished by their farming skills. The idea that fixed-rent contracts are typically given to relatively skilled tenants dates back to the agricultural (tenancy) ladder hypothesis of Spillman...
