With this information, the researchers carry through collections of data in the commerce and the too much establishments that carry through sales of products or services for consumers. With the information of prices gotten in the research in field and with the weight of each one of the item in the budget of the families, by means of calculations if he gets the inflation for the period measured for the IPCA. The IPEA (Institute of Applied Economic Research) recently carried through a work where it in recent years presented the variation of the prices of the products and services measured by the IPCA. In accordance with this study, that grouped the composition of the products and services in foods and drinks (with weight of 22,3%), services (with 23,0%), monitored (with 31,5%) and industrialized (with 23,1%), of 2000 the 2010 inflation in 2002 only exceeded the goal established for the government. Since 2005 that the goal of the inflation is of 4,5% with tolerance of 2,5 percentile points up and down in this year and of 2 percentile points in the other years. The industrial products that in 2001, 2002 and 2004 had been superior to the inflation goal, since 2005 come presenting always inferior increase of prices to center of the goal. The monitored ones, that they are basically public services that had been privatized such as telephony, water, public energy, transports, had had well different behaviors of 2000 the 2005 and 2006 until the moment.
In the first period, the increase of the prices was always superior to goal of inflation and in as the period, always inferior. The main reason of this change in the behavior of the prices of these services was the alteration of the method of readjustments of the tariffs waked up since the privatization. This change more took the application of index adjusted for the reality such as the use of spread sheets of costs. The services in generalities had only had a more compatible behavior with the superior band of the inflation goal during last the ten years, having exceeded this limit in 2010. The behavior of food and drinks in last the eleven years has varied very, since 20.7% in 2002 to an increase of 1,7% in 2006. To control the inflation is basic, however, if it does not have to forget it growth the economy and generation of income and wealth in our country. Factors as the exchange tax that in recent years if has kept below of what if it can consider as adequate if on the other hand have helped to hold the increase of the prices, for another one have soldier on barrack duty the economy to grow more strong, notadamente by means of increase of the exportations and the reduction of the importations of consumption goods and services. Moreover, as the astronomical interests that Brazil is practising currently to hold the inflation have corroded the public finances and flooding the country of dollars that still more raise the costs for the Brazilian government. This necessary politics of changes that lead to the moderation of the inflation, adjustment of the tax of exchange for a platform that does not harm the Brazilian exporters and diminishes the brutal cost of Brazil is having at the moment with the reserves in foreign currencies that do not stop to grow.
