In 2008, Zimbabwe issued a 100 trillion Zimbabwe dollar note and the inflation rate rose to over 7.68 billion percent per month! This series of seven videos begins with the story of Zimbabwe’s hyperinflation before taking a step back to ask: what is inflation and what are its causes? How is it measured? Does it have any costs? This unit also introduces the quantity theory of money, and with it, one of the most important identities in macroeconomics.
