1. Inflation may cause harm for growthIn 1998, Atish Ghosh and Steven Phillips has used data on growth Capita GDP annually by price comparison and data on inflation by CPI on average in 145 of the country in the period 1960-1990 with the observed phenomenon of 3603 and Multivariate regression method used by the group to verify the relationship between inflation and economic growth. Atish Ghosh and Steven Phillips said that the relationship between inflation and growth is not simply a one-way relationship that is the inflation impact on growth or increase the impact on inflation; between inflation and growth have non-linear interactions. Correlation between inflation and growth in the same economic cycle. The results of the verification of data through the following principal findings:(1) Between inflation and growth were related inversely; inflation is not only a meaningful factor in the statistical proof that also is an important decision factor for growth. Inverse proportion relationship between inflation and growth appears in the check according to the countries and according to both the dăy of the time; (2). When low inflation around 2%-3%, between inflation and growth have proportional relationships; when inflation is high, between inflation and growth rate of the reverse relationship is expressed through the function is convex. Research results indicating when inflation at rates from 10% to 20%, then the growth rate will decline; (3) the inflation threshold exists: "inflation Threshold for an increase in the level of 2.5% ", when inflation is higher than the threshold of 2.5% will have reduced the impact on economic growth. Some researchers (Joao Ricardo Faria; Francisco Galrao Carneiro; Michael Bruno and William Easterly) looked at the impact of high inflation and the inflation shock for growth over the long term, going to get: in long-term economic growth is not affected by high inflation and the inflation shock as well as political shocks, the commercial exchange rate in particular, the economy recovered very strongly during the high inflation was tame
