- W2901511056 abstract "RESUMO O estudo analisa o impacto dos investimentos em P&D nas vendas das firmas, tomando uma amostra de 2.000 firmas. Usando a técnica de variáveis instrumentais na regressão quantílica, o coeficiente de elasticidade em P&D apresentou-se consideravelmente maior em relação ao método tradicional (estimador de Koenker e Bassett) e com inversão de tendência com aumento dosquantis. O estimador de regressão quantílica com variáveis instrumentais revela os riscos de tendenciosidade e inconsistência quando o pressuposto de exogeneidade é violado. Ao contrário dos resultados apresentados na literatura, as implicações deste estudo mostram que firmas com maior volume nas vendas (quantis superiores da distribuição condicional) obtêm maior retorno no uso dos investimentos em P&D." @default.
