Resumo Este trabalho busca testar se o BNDES desempenha um papel compensando potenciais imperfeições no mercado de crédito no que diz respeito a investimentos em P&D. Para isso, propomos uma análise de regressão com interação inspirada em Maskus et al. (2012). Utilizamos dados de 22 setores das indústrias extrativa e de transformação no Brasil, tendo como fontes principais a PINTEC, o BNDES e a PIA, compreendendo 6 triênios a partir de 1998 até 2014. Nossos resultados oferecem algum suporte para a hipótese de um papel positivo do BNDES: o crédito do BNDES está mais positivamente correlacionado com a intensidade de P&D em setores da indústria e períodos em que é maior a dependência de capital (financeiro) externo.
This paper analyses how income distribution, Intellectual Property Rights and other regulatory policies such as minimum quality standards determine pricing strategies in a dynamic context where a monopolist periodically introduces new generations or upgrades of a durable good. This paper differs from Inderst's (2003) or Koh's (2006) in that discrimination through quality and screening take place in a context where consumers buy several (not a single) versions of the durable good during a lifetime. It differs from Glass (2001) in that here an equilibrium may emerge in which different consumer types replace their durable generations with different frequencies. Our model's predictions or stylised facts are illustrated with data from the last Brazilian POF (household budget survey).
