This note introduces the problem of indexation of wages, exchange rate and other prices in the Phillips' curve. With this aim we developed a simplified model of inflationary process decopositing it in inertial inflation, the Phillips' curve and administered or supply shock inflation. Using this model we first show that a supply shock shifts the Phillips' curve accelerating the trend rate of inertial inflation. Second, that a continuous demand pressure through Phillips' curve leads to continuous acceleration of the inflation rate. And third, that a rise in the rate of unemployment may lead to an oligopolistic increase in the profit margin, which also leads a shift in the Phillips' curve and an acceleration of the inflation.
