 - São Paulo :  Nobel,  jan./mar. 1996 
<br/><br/> This paper examines the relative price’s behavior of the Brazilian industry in the phases of expansion and retraction of the economic activity level between 1974-1994. The results suggest that relative prices of the oligopolistic sector accelerate more (less) in periods of recession (expansion) then the competitive sector. The main conclusion is that given the differentiated behavior in the price and low competition of the majority of the Brazilian industry, it is likely that the recession result of a restrict economic policy will be absorved by the competitive sector “in favour” of the oligopolistic sector
