RESUMO

This research work introduces a new detailed data-set of high frequency observations on prices, sold quantities and inventories by a brazilian long steel wholesaler, from nov, 1997 to dec, 2005. From empirical analysis, we tried to verify whether the implementation of protectionist measures, through imposition of technical standards to steel imports, brought significant impacts on price formation on brazilian market. We demonstrate that the difference between the time series models before and after the imposition of the restrictions is very clear: while the model SARIMA(0,0,2)(0,1,0) fits better with the series before, ARIMA(0,1,1) fits with the series after the restrictions date, suggesting that the measures leaded to a new business environment, which permitted the brazilian mills achieve price levels not compatible with a competitive market.
