RENDON CARDONA, Andrés Julián. Oligopolistic differentiation of the Colombian green bean coffee in the US market. []. , 17, 36, pp.99-125. ISSN 1657-4206.

New Empirical Industrial Organization (NEIO) literature notes that imperfect foreign competition among commodities may be characterized by prices, quantities and product differentiation. This paper shows that the effectiveness of the differentiation strategy of Colombian green bean coffee in the US market has caused Colombia to compete in terms of quantities with its major opponent, Brazil. In order to show it, this paper brings a set of models which allow us to identify the competitive structure followed by Brazil and Colombia in the United States market of green bean coffee imports. These models are evaluated through a likelihood ratio test to determine which of them best explains the data. Stackelberg is the best model showing Brazil's leadership in terms of quantities.
