RESUMO: O presente artigo utiliza-se de uma estimação em painel, considerando-se seis estados brasileiros, para verificar a influência sobre as vendas no varejo de três componentes macroeconômicos, tais como a renda real média, a taxa de desemprego e a taxa de juros, entre os anos de 2004 e 2011, período no qual a economia brasileira observou expressivo crescimento econômico. Optou-se por uma estimação em SUR (regressões aparentemente não correlacionadas) para ampliar o ajuste ao longo dos espaços geográficos estudados. Como resultado geral, nota-se que as vendas ao varejo são elásticas, contemporaneamente, à renda real média. As demais variáveis, taxa de desemprego e taxa de juros demonstraram-se inelásticas e em alguns estados sequer significativas, além de se manifestarem com uma defasagem de três meses. ABSTRACT: This paper performs a panel exercise, including six Brazilian states, to determine the influence on retail sales of three main macro-indicators, such as personal income, unemployment rate and interest rates, in the 2004-2011period, when Brazilian economy showed an expressive economic growth rate. A SUR (seemingly uncorrelated residuals) methodology estimation across Brazilian states was conducted. All results point out that retail sales and personal income are linked contemporarily and, at the same time, elastic. As for unemployment rate and interest rates, despite their significance in most states, both are inelastic to explain retail sales and lagging three months in the macroeconomic context.
