This report presents multifactor productivity indices of Brazil's agricultural sector. The imposed restriction, that the production technology is constant returns to scale, influences calculation of indices. The difference between the constant returns-to-scale index and the more general index derived here indicates that constant returns to scale is an overly restrictive assumption for Brazilian agriculture. This report presents indices for eight categories of inputs (energy, feed and seed, fertilizers, labor, land, pesticides, livestock, and machinery) and describes and documents the data used in calculation of the indices.
