Elasticidade-preço da demanda por etanol no Brasil: como renda e preços relativos explicam diferenças entre estados

Abstract: Este artigo estuda a demanda por etanol no Brasil no período 2001-2009, considerando as características regionais de renda e de preços relativos. Essas características explicam variação relevante na elasticidade-preço da demanda, aspecto até então desconsiderado em estudos anteriores. Foi estimado um modelo econométrico a partir de um painel de dados estaduais mensais, no qual variáveis instrumentais foram usadas para controlar a endogeneidade na análise da demanda. Conclui-se que a demanda é mais elástica em … Show more

“…According to Orellano et al ., 11 there is an identification problem with demand estimation models that use aggregated data because the data on observed sales and prices correspond to points of market equilibrium. The researcher therefore faces a classic endogeneity issue in these models because prices are explanatory variables correlated with the regression error term.…”

“…The researchers reported that ethanol was a price elastic good and that the short-term price of ethanol and cross-price elasticities of gasoline increased in the post-flex-fuel period. Similarly, Orellano et al 11 analyzed the demand for ethanol in 2001-2009, considering the regional characteristics of income and relative prices and using monthly state data with instrumental variables (ethanol prices from adjacent regions) to control endogeneity. They suggested that demand is more elastic in poorer states and that the relative price (ethanol/ gasoline) is close to 70%.…”
