The purpose of this paper is to describe the long-term trends in German agricultural development for the period since 1850 and to test the "induced innovation" hypothesis against German experience.

The focus of this analysis is to measure, by use of production functions, the contribution to total output of not only the quantity of traditional inputs (land, labor, fertilizer, etc.), but also the quality of certain inputs, particularly irrigation; technology; environmental factors (soil...

This study examines the argument that farm size is associated with technical efficiency. A non-parametric, frontier analysis method is used, together with some additional statistical analysis. Although some gains in efficiency appear as we move toward larger farms, they do not seem to be...

The main purpose of this study is to measure, among commodities and among agro-economic zones, the economic efficiency and the real cost of earning foreign exchange through producing and exporting eight selected commodities by using the concepts of social profitability and domestic resource...

Accurate estimates of returns to scale require that inputs and output are measured without error and that environmental and managerial differences among firms of varying sizes are taken into account. Measurement problems affecting estimates of returns to scale in agriculture include: (1)...

Measures of productivity growth are often pro-cyclical. This study focuses on measurement errors in capital inputs, associated with unobserved variations in capital utilization rates, as an explanation for the existence of pro-cyclical patterns in measures of agricultural productivity. Recently...

There have been substantial increases in our understanding of the process of agricultural development over the last half century. Yet the productivity gap between developed and developing countries has not narrowed. In this paper I assess (a) the resource and environmental constraints and (b)...
