The Central Bank

• Ensures the currency's purchasing power is maintained.

Inflation

• Rising prices made it difficult for Doña Marta to fill her basket years ago.
• The basket being full indicates positive economic conditions today.
• Inflation is decreasing, implying money is not losing value.
• The DANE (National Administrative Department of Statistics) calculates a weighted average of goods consumed by various income groups to determine the family basket's composition.

Economic Challenges

• The Central Bank or the Banco de la República are concerned when Colombians like Doña Marta struggle to afford their basket.
• They wish citizens had as much money as sheep have wool.
• If the bank prints excess money relative to the country's production, prices rise and Doña Marta's basket becomes harder to fill.
• Her husband, Don Arturo, works in a wool factory.
• Don Arturo receives money for selling wool, which is his salary and part of the productive apparatus.
