Abstract
Innovation and diffusion are imbricated concepts. Understanding diffusion of innovations means advancing knowledge about technological progress. There is in the literature the understanding that diffusion is context-dependent. The objective of this paper was to analyze the innovations diffusion in Brazil, considering their socioeconomic particularities. With consumption data collected from a national survey (PNAD) for six products in different periods, diffusion curves were estimated from Rogers (1962) and coefficients calculated according to Bass (1969). The main results were: 1) the model was useful for the diffusion analysis in Brazil, stating that Rogers and Bass are relevant theories also for this context; 2) the diffusion of the products investigated is in different stages in this economy, and is, essentially, an imitation process; and 3) should be considered the diffusion peculiarities for the Brazilian economy, since there seems to be endogenous factors that make it differentiated.
