Confidence indices developed by Fedesarrollo, an independent center for economic studies, via surveys conducted among the public in general and businessmen. These surveys include questions about perceptions and expectations on economic activities like consumption or demand of goods and services, industrial production and commercial development. Indices updated on monthly basis. Industrial index <COCCIC index> and commerce index <COCCCOC index> are presented with a one-month lag. In order to determine the consumer confidence index, a net balance is calculated as a result of subtracting the percentage of negative answers from the percentage of positive answers to the 5 questions that are part of Fedesarrollo's monthly survey.
