Lisa’s “Money” took over the airwaves thanks to TikTok. The song addresses several economic concepts. First, currency is considered a medium of exchange, and cash is perfectly liquid. Understanding the important role that currency plays is critical to market transactions. Second, the sum of currency and checkable deposits are equivalent to the M1, Money Supply. Throughout the song, Lisa assures us that cash and her bank account support her lifestyle. Lisa provides several lines about her purchasing and spending behavior, supporting the definition of the velocity of money. Economists measure the velocity of money to examine how currency travels throughout the economy, measuring the quantity of exchanges.
