The Bureau of Statistics and Census of the Comptroller General of the Republic hereby presents the methodologies used to calculate the main variables of the Annual National Accounts in Panama, from the main components of gross domestic product (GDP). For the base year 2007 was prepared Table Supply and Utilization (COU), which is a picture of macroeconomic consistency, which has produced and imported supply and destination for goods or services (consumed, invested or exported) in addition to the components of production, intermediate consumption and value added according to economic activity. Because of the complexity of its preparation, years that are not available a calculation of the series in economic activities are applied to the base year annual indicators associated with each activity. Here are the main methodological aspects used for measuring the value added in the various categories of economic activity that make up the GDP and of their components of income and expenses.
The COU was prepared by object produced by row and by economic activity as column, only for the base year 2007. For 2007, all activities were confronted in their levels of production, use of goods and consistency between supply, including imported, and their use as inputs or final demand. Where there were inconsistencies, was used to investigate direct sources alternative references. In calculating the series for economic activities, information is used from surveys, financial, and administrative records. For some activities data which do not have adequate coverage, applies to the base year data, an Annual indicator associated with the activity. The SNA recommends that if possible, be made regular changes of base year even five years each.
