This paper studies the effect of economic stability on the growth of 17 Latin American countries between 1980-2014 for three different economic growth groups; low, middle and high. The hypothesis is that a more unstable economy, meaning, a larger inflation and product volatility, negatively affects investments, which affects growth. In order to contrast this hypothesis, a random effect model is estimated using a panel of 17 Latin American countries in a 35-year period, in which countries are classified according to the k-median cluster method. Results indicate that instability affects negatively the economic performance of the region, particularly countries with a smaller growth. Because of this, the recommendation for such cases is the application of anti-cyclic and anti-inflationary policies.
