This article analyzes competition indicators in the Portuguese economy in the period 2000-2009, focusing on the differences between tradable and non-tradable sectors. The article computes the Herfindahl-Hirschman index and the price-cost margin, i.e., classical concentration and profitability measures, for a large set of markets. The analysis carried out is fundamentally distinct from the one conducted by competition authorities, aiming to set an overall scenario for competition developments. The article concludes that, although there are apparently no widespread problems, there is substantial room for improvements in the business competition environment in several markets, notably in the non-tradable sector.
