Money and Banking: What Everyone Should Know

What is money? Consider the fundamental nature of money as a social contract and a social institution that coordinates economic activity. Explore the connections between financial institutions and economic well-being, including the importance of "stable value money" to trade and the critical roles of healthy banks, efficient asset markets, and monetary policy.

Money developed as a medium of exchange to facilitate trade. Here, learn about five stages in the evolution of money. Beginning with barter, trace the rise of commodities as money, the invention of coins, paper money backed by precious metals, and finally our era's "fiat" money, which has value by agreement alone.

Study the invention of paper money in the history of goldsmiths issuing paper receipts backed by gold deposits. Then trace the important history of the gold standard, upon which nations pegged the value of currencies, and the reasons the gold standard was abandoned in 1971.

The U.S. government's role in financial affairs has been historically controversial. Learn about the two failed attempts in early U.S. history to establish a central bank, followed by the system of "national" banks chartered in the 1860s. Follow key issues surrounding national currency and coinage, leading to the Federal Reserve Act of 1913.

Finance is not just the business of the wealthy. Here, study nontraditional models for solving economic problems, from examples of local currencies galvanizing local economies to "microfinance" arrangements such as Bangladesh's Grameen Bank, which create highly successful savings and loan programs for the poor.

This lecture investigates the factors governing inflation, beginning with an inflation history of the United States over the last century. Learn about the correlation between inflation and the consumer price index, and how inflation is triggered by excess money growth. Also, review inflation's detrimental effects and costs.

The history of hyperinflation offers both a compelling story and a cautionary tale of inflation's damaging effects. Trace the root causes of extreme inflation in governments that finance deficits by printing new money. Then, study key cases of hyperinflation, its "vicious circle" quality, and the inevitable fiscal reform that ends it.

Explore the meaning of "investment" in economics as increases to a nation's "capital stock" - the equipment, technology, and human resources used in the production process. Then see how investment is made possible by domestic saving and foreign borrowing, and how investment is critically related to economic growth.

Understanding how interest rates work sheds important light on our economy. Study the difference between the "nominal" or agreed-upon interest rate in a loan transaction and the "real" rate of interest. Learn how the "real" rate factors in the rate of inflation to determine the actual cost/benefit of borrowing and lending.

Financial intermediaries or "middlemen" play an important role in modern economies. Investigate how intermediaries such as commercial banks facilitate borrowing and lending, which provide valuable services to each party. Afterward, study the fundamental types of intermediary institutions, including savings banks, mutual funds, money market funds, and insurance companies.

In learning how commercial banks operate, examine the sources from which banks acquire their funds and how they use the funds they acquire, as well as how assets and liabilities function within banks. Finally, study three formal definitions of money, and how banks literally create money in the process of making loans.

Investigate the role and importance of central banks as they provide banking services to commercial banks, focusing on the U.S. Federal Reserve. See how central banks control an economy's interest rates and create money, and how their ability to increase or decrease the money supply makes them the world's most powerful financial institutions.

Present value is an important formula for computing the current value of payments that will be received or made in the future. Learn how present value is used, in the examples of determining the current value of a savings bond and how much to save per year for future college tuition.

This lecture explores how financial decisions are made in the face of future uncertainty. Using the examples of both a dice game and a real-world business strategy, study the statistical tool of "expected value" as a method of predicting possible outcomes. See how the probability of expected profits influences business decisions.

Economists have developed ways of assessing people's willingness to take on risk in financial decision making. With reference to the "St. Petersburg Paradox," a classic problem relating to odds in gambling, observe how individuals tend to value the dollars they might lose more highly than the dollars they might win.

Bond markets play a key economic role by channeling funds from savers to government and private entities that need funding beyond their current revenues. In this lecture, study the various types of bond instruments, including Treasury bills, notes, and bonds. Learn also about important factors underlying the federal deficit and the national debt.

In a deeper look at bonds, investigate how secondary markets for bonds operate and what they offer investors. Study fundamental concepts including the "yield to maturity" of bonds and the "holding period yield" in understanding the link between bond prices and interest rates and how economic events change them.

Changes in interest rates have widespread economic effects. Consider interest rates as market prices, set by the current market for credit. Then see how interest rates are determined in the long run by patterns of saving and investment, and in the short run by factors such as government deficits and recessions.

The many interest rates in different areas of the economy tend to change together over time. Here, learn about the key factors that govern this, beginning with the ways that interest rates adjust to expected changes in inflation. Observe also how risk in borrowing and lending affects the rate of interest.

The formula known as the "Expectations Hypothesis" allows analysts to forecast future interest rates and conditions in the credit market. Understand the intuition behind the hypothesis, study the formula itself as it tracks yields on Treasury securities, and see how it benefits borrowers considering mortgages and loans.

Stock markets provide individuals the chance to share in the ownership and profits of corporations. Investigate the history of stock markets, their basic functions on behalf of investors, and how trades are made. Finally, learn about the various stock indexes that track the markets, and how mutual funds operate.

What determines prices in the stock market? Approach this question first through the "market fundamentals" model of stock prices, a formula linking a firm's capital, profits, and dividends to its share price. Contrast this with the "capital asset pricing model," which evaluates the rate of return an investor requires.

This lecture introduces the fascinating group psychology of stock investing. Study the phenomenon of stock market "bubbles," in which prices are driven up without reference to profitability data. Then, grasp the "bubble" mind-set, which triggers speculative buying and selling based only on what others are paying.

Derivative securities play an important role in finance by allowing business decision makers and private investors to lower risk. See how derivative securities are created using underlying products, and study the major types of derivatives and how they function, including stock options, commodities futures, mutual funds, and "collateralized" debt obligations.
