The articles were divided into three topics: i) inflation persistence; ii) price formation; and iii) wage rigidities. Regarding the first of these, the book includes six papers focusing on identifying general changes in inflation trends, as well as on the degree of inflation persistence. The second topic brings together four papers studying price formation from a macroeconomic viewpoint, using direct surveys of producers, or calculations of frequency and duration using microdata from consumer price indexes or retail points of sale. After analyzing this information, the authors identify the general behavior of producers for setting prices and changes resulting from inflation shocks. The book ends with two articles on wage rigidities, which are also taken from a macroeconomic standpoint. The researchers use individual surveys and surveys aggregated by the type of firm or business sector. This information allows them to identify some relations between wage levels (and their rigidity –degree and direction–) and the average age of workers, the type of firm and the state of the economy, among other factors, in order to obtain information for supporting economic policy decision-making.
