Monetary Theory (2026 - 2026)

In lecture two, we learn about the mechanics of a gold standard, focusing on how supply and demand for monetary gold determine money’s quantity and purchasing power. Dr. White explains the system’s self-correcting mechanism, where changes in demand spur adjustments in gold mining, restoring equilibrium and supporting long-run price stability. Comparing gold and fiat systems, the lecture highlights historically lower inflation, greater price predictability, and stronger fiscal discipline under gold. Finally, we review common objections about gold resource costs and consider why economists today generally oppose returning to a gold standard.

In lecture three, we examine banks’ role in issuing money under a gold standard, explaining why people prefer banking services to direct gold transactions and what constrains banks without legal limits. We explore fractional-reserve banking as a voluntary system where banks provide payments and interest while lending a portion of deposits. The lecture concludes by showing how market forces—adverse clearings, reserve losses, and the price-specie flow mechanism—naturally limit money creation, allowing competitive banking systems to self-regulate without central bank oversight.

In lecture four, we explore fiat money—currency created by government decree rather than commodity backing—tracing its rise after wartime suspensions of the gold standard and the shift to central bank control of the money supply. We examine the quantity theory of money, showing that increases in money supply drive price levels and make central banks responsible for inflation. The lecture concludes that institutions like the Federal Reserve control inflation through monetary policy, challenging alternative explanations such as deficits or “greedflation” as primary causes of inflation.

In lecture five, we consider whether government intervention in monetary services improves public welfare, using concepts like market failure and Pareto efficiency. We evaluate public goods, externalities, and natural monopoly arguments, finding little support for intervention since money is largely rival and excludable, and network effects are typically internalized by markets. The lecture concludes with Friedman’s optimum quantity of money theory, which advocates mild deflation to reduce the cost of holding money and maximize welfare, though such policies have proven impractical in practice.

In lecture six, we analyze arguments for government involvement in banking, particularly the claim that unrestricted banking is inherently unstable and prone to runs. We explore the Diamond-Dybvig model that justifies deposit insurance, contrasting random panic theories with "bad news" explanations for runs. Dr. White concludes that well-capitalized, diversified banking systems—like Canada’s—are stable, and that U.S. instability stemmed from legal restrictions, leading to the Federal Reserve as a political compromise rather than an economic necessity.

In lecture seven, we study the underlying causes of money growth and inflation, examining why central banks issue more money than is consistent with stable purchasing power. We delve into the concept of seigniorage—the profit from money creation—tracing its historical roots from medieval mints that debased coins to modern fiat money systems where governments can finance spending by printing currency. The lecture analyzes how governments facing fiscal pressures, particularly during crises, may resort to excessive money printing, potentially leading to hyperinflation, and discusses the growing U.S. debt-to-GDP ratio and its implications for future monetary policy and inflation risk.

In our eighth and final lecture, we discuss the challenges of maintaining sound money in a fiat monetary system and examine potential solutions to prevent fiscal problems from undermining the dollar's purchasing power. We delve into the debate over central bank rules versus discretion, analyzing why monetary policy cannot permanently reduce unemployment or boost real economic growth. Dr. White concludes our course by evaluating various monetary policy targets, including inflation targeting versus nominal GDP targeting, and considers alternative approaches such as Hayek's proposal for competitive currencies and the potential role of Bitcoin as a monetary standard.
