The Opportunity Cost of Holding Money
• You could be earning interest on the money!
• Opportunity Cost therefore changes with interest
rates
• We use short-term rates as the cost
• When we use the term money, we consider it to mean
funds that will be used for transactions in the short
term, not funds to be invested in longer term projects
