Lisa — Money

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.

Kiatnakin Bank — Saving for your dream


This young Thai kid dreams of being an astronaut and making great scientific discoveries, but he’s got to save enough Baht (Thai currency) to be able to afford to the telescope. For reference, 2500 baht is about $75 US. The young boy is tempted by ice cream, street food, video games and toys, but he maintains his frugalness and saves up enough to buy the telescope. After enough time, he rushes to the store to buy the telescope, only to find out that the telescope now costs 3500 baht. The message is clear, inflation occurs and makes the value of money deteriorate over time. This Thai bank is encouraging savings to help combat that.
