Total Factor Productivity in Uk Agriculture, 1967‐90

Abstract

Indices of total factor productivity (TFP) measure aggregate output per unit of aggregate input, providing a guide to the efficiency of agricultural production. This paper outlines the relationship between production functions and TFP indices. An index for the period 1967‐90, constructed from the UK aggregate agricultural accounts, shows that TFP grew at an average rate of 1.9% per annum and that TFP growth has increased since the UK joined the European Community. At the aggregate level, this change seems to be explained by increased aggregate output and decreased aggregate input, in about equal proportions. Disaggregation shows the intensification effect of the CAP price regime. There has been rapid growth in the output of farm crops, relative to other enterprises, and in the use of agricultural chemicals.

The Agricultural Productivity Gap in Europe

“…For agriculture, existing empirical estimates suggest that labor income share is in the ballpark of 0.4–0.5 (Hayami and Ruttan ; Mundlak ). Similar values are reported for the United Kingdom in Thirtle and Bottomley () and Fuglie (). To ensure comparability of our results with those in Herrendorf and Schoellman (), we assume a labor income share of 0.44 for agriculture .…”

“…Los índices de miden el agregado de producto por unidad de insumo agregado y ofrecen así una guía para observar la e ciencia de la producción agrícola (Thirtle y Bottomley, 1992). Son pocos los estudios en que se calcula la por cultivos, debido a la di cultad de controlar los niveles especí cos de insumo y producto.…”

Theory, measurement, policy and politics: Agricultural R&D and productivity in three countries

“…Better defence required better data but the TFP data available to Thirtle and Bottomley (1992) was not adequate to establish the causality running from R&D to TFP. By the late 1990s government attitude changed to one of freedom of information and collaboration with academia.…”
