Capital accumulation and the growth of aggregate agricultural production

Abstract

Haley, S.L., 1991. Capital accumulation and the growth of aggregate agricultural production. Agric. Econ., 6: 129-157.This report empirically examines the role which capital accumulation plays in the growth of agricultural production potential. The report assumes that the degree to which available technology can be implemented in a nation's agricultural sector depends on accumulated investments that have been made in the sector. Results from estimating aggregate agricultural production functions show the primary importance of rural labor in accounting for agricultural GDP and crop production. Capital accumulation is the dominant explainer of livestock production. Estimation results support the conjecture that capital tends to save scarce land resources (substitute relationship) and use rural labor (complementarity relationship). Output supply elasticities derived from the estimated equations tend to be large. The large elasticities imply that price distortions have had large impacts on resource use and production. t, metric tonne = 1000 kg. 0169-5150/91/$03.50

Sources of agricultural productivity growth and stagnation in sub-Saharan Africa

“…Many econometric studies have examined agricultural productivity differences among countries (e.g, Nguyen, 1979;Mundlak and Hellinghausen, 1982;Antle, 1983;Hayami and Ruttan, 1985;Lau and Yotopolous, 1989;Haley, 1991;Ghura and Just, 1992). These studies, which estimate aggregate agricultural production functions from international data, have been important in quantifying the relative importance of such factors as modern input use, research, infrastructure, and capital accumulation on agricultural growth.…”

New Look on the Specific Factor Model: Empirical Evidence from Manufacturing Industries in Tanzania

“…Unfortunately, there are no data for agriculture and services for Tanzania. In the literature, Haley (1991) reports that the Sub-Saharan African labor share in agricultural value-added is 0.72 and the capital share is 0.16. For the service sector, labor and capital shares are 0.7 and 0.3.…”

Rural livelihoods in the arid and semi-arid environments of Kenya: Sustainable alternatives and challenges

“…In sub-Saharan Africa (SSA), this has rarely been the case, since most household-level diversification is both non-farm and nonrural in character. There is evidence, however, that people can reinvest in agriculture using non-farm incomes (Haley, 1991). Alleviation of credit constraints and reduction of the risk of innovation can be achieved through this means.…”
