P. R. de  aAn economic model for establishing priorities for agricultural research and a test for the Brazilian economy.  aPurdue: Purdue Universityc1974  a234p.  aTese Doutorado.  aThe potential contribution of technical change to agricultural development has been reconized for some time now. However, it has only recently been fully appreciated that technical change can take alternative routes in its resource-saving effects, and that the particular route that it takes is conditioned by relative factor scarcities. Increasing attention is being given to the problem of the management of research resources, and to the importance of allocating such resources according to criteria or some sense of priority. More particulary, policy-makers in Brazil have been giving more attention to agricultural research and to the importance of a sense of priorities in carryng out such research. Therefore, the search for criteria by means of which scarce research resources might be allocated should assist policy-makers as well as research managers. The specific objectives of the present study were to: (1) develop and analytical framework which provides a basis for establishing agricultural research priorities, (2) develop empirical models which contain the relevant parameters and which can be estimated from available data, or for wich parameters can be taken from other sources, (3) estimate the appropriate parameters, determine changing resource scarcities, and evaluate recent technical change in Brazil, (4) draw implications and make recommendations for the allocation of research resources in Brazil.  aagriculture  aresearch  aAgricultura  aPesquisa  aAspecto econômico  aEconomic aspects
