It has been updated, Boxes 19-2 and 19-5 have been added, and other boxes have been renumbered accordingly. Introduction to the MaterialThe Great Depression in the 1930s presented an economic crisis of enormous proportions. Between 1929 and 1933, real GDP in the U.S. fell by almost 30% and unemployment reached an all-time high of almost 25%. While the economy grew fairly rapidly from 1933-37, unemployment remained in the double digit range. In 1937/38, there was another major recession and the unemployment rate remained above 5% until 1942. In the 1930s unemployment averaged 18.8%, but by 1939 real GDP had recovered to its 1929 level.The classical economists of the time were not equipped to explain the existence of such substantial and persistent unemployment or to prescribe policies to deal with it. Only in 1936, in John Maynard Keynes’book The General Theory of Employment, Interest and Money, was a macroeconomic theory introduced upon which policies to keep the economy out of future recessions could be based. Keynes’ theory provided an explanation of what had happened during the Great Depression and suggested policies that might have prevented it.The stock market crash of 1929 is often seen as the catalyst for the Great Depression but, in fact, economic activity actually started to decline even before the crash. What might well have393been an average recession turned into a very severe depression due to the inept economic policies employed at the time. The Fed failed to provide needed liquidity to banks and did little to prevent the collapse of the financial system. The huge contraction in money supply due to the large numbers of bank failures caused the economic downturn. Fiscal policy was weak at best. Politicians concerned with balancing the budget raised taxes to match increases in government spending, so the decline in aggregate demand was not counteracted.Many other countries also suffered during the same period, mainly as a result of the collapse of the international financial system and the enactment of high tariffs worldwide. These policies were designed to protect domestic producers in an attempt to improve each country’s domestic trade balance at the expense of foreign trading partners. However, the attempts to "export" unemployment ultimately resulted in an overall decline in world trade and production.In the U.S., many institutional changes and administrative actions, collectively known as the New Deal, were implemented in the 1930s. The Fed was reorganized and new institutions were created, including the FDIC, the SEC, and the Social Security Administration. Public works programs and a program to establish orderly competition among firms were also implemented.The experience of the Great Depression led to the belief that the economy is inherently unstable and active stabilization policy is needed to maintain full employment. Keynes was an advocate of active government policy. In his work, he explained what had happened in the Great Depression and what could be done to avoid a recurrence. Many years later, Milton Friedman and Anna Schwartz offered a different explanation. In their book A Monetary History of the United States, Friedman and Schwartz argued that the severe decline in money supply, caused by the Fed’s failure to prevent banks from failing, was the reason for the severity of the Great Depression. They claimed that monetary policy is very powerful and that fluctuations in money supply can explain most of the fluctuations in GDP over the last century. This argument provided the impetus for new research on the effects of fiscal and monetary stabilization policies. While economists are still debating these issues, we can conclude that monetary policy can affect the behavior of output in the short and medium run, but not in the long run. In the long run, increases in the growth rate of money supply will simply lead to increases in the rate of inflation. Box 19-3 gives an overview of the monetarist positions on the importance of money for the economy, while Box 19-2 quotes Fed Chairman Ben Bernanke, who admits that the magnitude of the Great Depression was indeed the result of the Fed’s action—or, more accurately, inaction.The link between inflation and monetary growth can easily be derived from the quantity theory of money equation:MV = PY ==> %∆M + %∆V = %∆P + %∆Y ==> m + v = π + y ==> π = m - y + v In other words, the rate of inflation (%∆P = π) is determined by the difference between the growth rate of nominal money supply (%∆M = m) and the growth rate of real output (%∆Y = y), adjusted for the percentage change in the income velocity of money (%∆V = v).Figure 19-1 shows that trends in the rate of inflation and the growth of money supply (M2) have been somewhat similar over the last four decades. There is plenty of evidence to support the notion that in the long run, inflation is a monetary phenomenon here in the U.S. as well as in other countries. However, there are short-run variations, indicating that changes in velocity and output growth have also affected the inflation rate. By the mid 1990s, the relationship between394M2 growth and inflation had largely broken down, even for the long run. It is still true, however, that there has never been inflation in the long run without rapid growth of money supply, and the faster money grew the higher the rate of inflation.Although there is no exact definition, countries are said to experience hyperinflation when the inflation rate reaches 1,000% annually. Countries that have experienced hyperinflation have all had huge budget deficits which, in many cases, originated from increased government spending during wartime. A classical example is the German hyperinflation of 1922/23. In an economy experiencing hyperinflation, there is often widespread indexing, most likely to foreign exchange rates rather than to the price level, since prices are changing so fast. Eventually, hyperinflation becomes too much to bear and the government is forced to take harsh measures, including fiscal reform and the introduction of a new monetary unit pegging the new money to a foreign currency. Box 19-4 on the situation in Bolivia in the 1980s provides a good example of how hyperinflation can be stopped. It also points out that the costs are great in terms of decreasing per-capita income. In 1985, Bolivia stopped external debt service, raised taxes, reduced money creation, and stabilized the exchange rate. Inflation came down quickly, but per-capita income in 1989 was 35 percent less than it had been a decade earlier.In its fight against hyperinflation, Israel tried to keep unemployment rates low by instituting wage and price controls while also sharply cutting budget deficits and rationing credit. These measures reduced the rate of inflation significantly. In the late 1980s, the governments of Argentina and Brazil imposed wage-price controls but failed to supplement them with fiscal austerity, so the result was much less satisfactory, although they, like many South American countries eventually succeeded in lowering their inflation rates. In the early 1990s, countries in Eastern Europe experienced brief periods of high inflation during their adjustments from centrally planned economies to more market based economies (as shown in Table 19-6). There is no guarantee that periods of hyperinflation will not surface again. New Box 19-5 describes the situation in Zimbabwe where the decision made in 2006 to print more money to finance higher government spending led to inflation rates in excess of 1,000%.When inflation is high, policy makers must focus on reducing it without causing a major economic downturn. This is fairly difficult to accomplish, however, since labor contracts tend to reflect past expectations and new contract negotiations take time. In addition, it may be difficult for a central bank to gain credibility in its fight against inflation because of its behavior in the past. Credibility is important, since inflationary expectations adjust down faster if people believe that a government is serious in its attempt to reduce inflation. If this is the case, the expectations-adjusted Phillips curve shifts to the left sooner and the economy adjusts more quickly to the full-employment level of output at a lower inflation rate. But some increase in unemployment is almost always needed to reduce inflation, since real wages need to adjust down to their full-employment level. The costs to society are often measured in terms of the sacrifice ratio, that is, the ratio of the cumulative percentage loss of GDP to the achieved reduction in the inflation rate.Probably all economists now agree with the monetarist propositions that rapid money growth tends to be inflationary and inflation cannot be kept low unless money growth is kept low. We also know that monetary policy has long and variable lags. But other monetarist positions remain more controversial, including those that suggest that the economy is inherently stable and that monetary targets are better than interest rate targets. The rational expectations approach can be seen as an extension of the monetarist approach, with a strong belief that markets clear rapidly395and people use all information available to them. This is why they advocate policy rules rather than discretion and place emphasis on the credibility of policy makers. Box 19-6 highlights the rational expectations approach.Any government that is unwilling to show fiscal restraint will ultimately be faced with excessive money growth and an increase in the inflation rate. Continued large government budget deficits create a policy dilemma for a central bank, which must decide whether to monetize the debt. If the central bank decides not to finance the debt, the increased borrowing needs of the government may drive interest rates up, leading to the crowding out of private spending. The central bank may then be blamed for slowing down economic growth. But if the central bank is worried about high interest rates and monetizes the debt in order to keep interest rates low, inflation may increase with the central bank taking the blame.The financing of government spending through the creation of high-powered money is an alternative to explicit taxation. Inflation acts like a tax since the government can spend more by printing money while people can spend less, since some of their income must be used to increase their nominal money holdings. The inflation tax revenue is defined as:inflation tax revenue = (inflation rate)*(the real money base).The ability of the government to raise additional tax revenue through the creation of money (and therefore inflation) is called seigniorage, and Table 19-7 shows some empirical evidence of the inflation tax revenue raised as percentage of GDP for some Latin American countries. However, there is a limit to how much revenue a government can raise through an inflation tax. As inflation increases, people reduce their currency holdings and banks reduce their excess reserves, since holding money becomes more costly. Eventually the real monetary base falls so much that the government's inflation tax revenue decreases. Figure 19-3 shows this graphically.While higher deficits can cause higher inflation if they are financed through money creation, higher inflation may also contribute to deficits, since inflation reduces the real value of tax payments. In addition, high nominal interest rates (caused by high inflation) raise the nominal interest payments the government must make on the national debt. The inflation-adjusted deficit corrects for that and is defined in the following way:inflation-adjusted deficit = total deficit - (inflation rate)*(national debt).Large government budget deficits and rapid monetary expansion seem to be inevitable parts of hyperinflation. The high rate of monetary expansion originates in the government's desire to raise its inflation tax revenue. However, the government can only be successful if it prints money faster than the public anticipates. Eventually, the process will break down, as the real money base becomes smaller and smaller.During the 1980s, the U.S. experienced very large budget deficits, which were temporarily brought under control in the late 1990s, only to increase sharply again in 2002. Figure 19-4 shows the trend in U.S. budget deficits as percentage of GDP, while Tables 19-8 and 19-9 give an overview of trends in the U.S. government's outlays and revenues. It is interesting to note that entitlements and interest payments on the national debt have increased significantly over the last396four decades. On the revenue side, corporate income taxes as a share of GDP have declined, while social insurance taxes have increased substantially.To highlight the role of the national debt in the budget, it is useful to distinguish between the actual budget deficit and the primary (non-interest) budget deficit. The U.S. budget deficits in the 1990s were actually more a result of high interest payments on the previously incurred debt than of government spending exceeding tax revenues. This is the legacy of past deficits. As the national debt accumulates, its interest costs accelerate, contributing even more to the budget deficit. The national debt is the result of all past and present budget deficits, and the process by which the Treasury finances the debt is called debt management. As old government securities mature, the Treasury issues new securities to make the payments on old ones.Robert Eisner has argued that it is important to recognize that the government has assets and not just debts. Any spending on infrastructure should be treated as accumulation of real capital and offset by the debt issued to pay for it. In other words, just like private spending, government expenditures should be separated into government “consumption” and government “investment.”With the U.S. gross national debt now exceeding $8.5 trillion (or over $28,000 per capita), it becomes important to consider its real burden. If individuals who hold government bonds consider an increase in government debt as an increase in their personal wealth, they will consume more and a lower share of GDP will be invested. This will lead to a lower rate of capital accumulation and slower future economic growth. Another concern is that foreigners hold a large part of the debt. Since the burden of future tax payments on this part of the debt (plus interest) will fall on U.S. taxpayers while the recipients of these payments will be foreigners, there will be a reduction in U.S. net wealth.High deficits cannot be sustained indefinitely, but as long as national income is growing faster than the national debt (implying a declining debt-income ratio), the potential for instability is fairly low. In the 1990s, there was widespread sentiment that government had grown too big and that sound fiscal policy had to be implemented. The fiscal restriction finally succeeded in turning the large budget deficits of the 1980s into budget surpluses in 1998. A debate quickly began among politicians about the best ways to put the surplus to use. Was it better to cut taxes, increase spending, or gradually pay off the national debt? The path chosen by the Bush administration was a massive tax cut, leading to renewed budget deficits in 2002.Another debate revolves around Social Security reform. There is increasing concern about the financial difficulties that the Social Security system will face in the near future. The system is financed to a large extent on a pay-as-you-go basis, with most of the earmarked taxes paid by current workers being used immediately to finance the Social Security benefits of current retirees. Such a transfer of resources from the young to the old can be accomplished if:• A growing population increases the ratio of workers to retirees. If population growth slows, however, then contributions have to be increased or benefits have to be cut.•High-income growth allows retirement benefits to be higher than past contributions, since the source of the benefits is the higher income of the younger generations. If income growth slows, however, then the system may face financing difficulties.•The political situation is favorable. A larger percentage of older people than younger people vote so the elderly can enforce the intergenerational transfer through the political system. But at some point, the young, who expect to receive lower benefits than their parents relative to their contributions, may refuse to support the system through their taxes.397While the Social Security system is often seen as a “forced savings system,” which makes sure that everyone accumulates some wealth for retirement, there is strong empirical evidence that the system actually reduces national saving due to its pay-as-you-go financing. The decline in saving reduces the rate of capital accumulation, which lowers productivity and future living standards.The Social Security trust fund actually has been growing as a result of the Social Security Reform of 1983, but current predictions are that the system will be bankrupt after 2045 when most of the baby-boomer generation will have retired. While most people do not wish to see the Social Security system totally abandoned, additional reforms are very likely in the near future. The central question is how to earn higher returns on the funds invested to prevent the system from insolvency and how to preserve equity for those who have already paid into the system. Suggestions for LecturingStudents who follow the news see stock prices fluctuate daily and they probably heard about past stock market bubbles and crashes. These students will be curious about the impact of major swings in stock market activity on the economy. Most people assume that the stock market crash of October, 1929 marked the beginning of the Great Depression and are not aware that economic activity had actually begun to decline earlier. A good way to introduce the material in this chapter is to ask: “Could a Great Depression happen again?” or “Do stock market crashes cause economic downturns?” Either will lead to a lively class discussion that can help to highlight several of the issues raised in the chapter. In this discussion the major stock market crash of October, 1987 and the decline in (especially high-tech) stock values that started in March, 2000 will undoubtedly come up. They are reminders that stock market bubbles will always eventually burst and that there is considerable risk associated with buying stocks.Most economists now agree that the magnitude of the Great Depression was exacerbated by inadequate fiscal and monetary policy responses. The Fed’s failure to inject e nough liquidity into the banking system to prevent failures led to a severe contraction in the supply of money and an economic downturn, and. Policy makers also did little initially to stimulate economic activity through fiscal policy. The severity of the economic situation in the 1930’s is not surprising to economists today, as no well-developed economic theory existed at the time that could deal with a disturbance of this magnitude. It was not until John Maynard Keynes offered an explanation of what had happened during the Great Depression and suggested ways to prevent future recessions that macroeconomists began to ponder the values of fiscal and monetary stabilization policies. It is no wonder that Keynes is seen by many as the “father of all macroeconomists.”Economic theories are generally pro ducts of their time and, as mentioned above, Keynes’macroeconomic theory was developed as a result of the Great Depression. His explanation and prescription for preventing future depressions were widely accepted, but did not have much impact on policy making in the U.S. until the 1960s, when the government followed (mostly fiscal) activist policies to ensure full employment.The handling of the major stock market crash of 1987 appears to indicate that policy makers have learned from past mistakes. Stock values dropped by more than 24% in October of 1987, but we did we not see a severe downturn in economic activity. Why not? For one, Alan398Greenspan, who had been appointed as chair of the Board of Governors of the Fed only a few months earlier, was conscious of what had happened in 1929 and immediately assured financial markets that the Fed would provide the liquidity needed to prevent a financial collapse. The Fed quickly started to undertake open market purchases in an effort to drive interest rates down. In addition, as a result of institutional changes implemented after the Great Depression, government now has a much larger role in the economy. Students should be aware that the Great Depression not only shaped modern macroeconomic thinking and approaches to stabilization policy, but also shaped the structure of many U.S. institutions. Instructors may want to spend some time talking about these institutions and their importance to our economy.It also should be noted that the economy was in much better shape when the stock market crashed in 1987 than it was in 1929. While we can only speculate on what would have happened had the economy been in worse shape, the existence of programs such as Social Security and unemployment insurance would have dampened the severity of a downturn by providing some automatic stability. In addition, the existence of the FDIC, which insures all bank deposits up to $100,000, now serves to avoid panic in financial markets and runs on banks.The recession in 1981/82, which was the most severe recession since the Great Depression and brought the unemployment level close to 11%, provides another good example that policy makers now react much more swiftly to major economic upheavals. Even though the recession was fairly severe, it did not last for an extended period, since expansionary policies were implemented almost immediately after the magnitude of the downturn became clear.There are still disagreements about the primary causes for the Great Depression and these should be clarified. The Keynesian explanation concentrates on spending behavior, that is, the reduction in consumption and the collapse of investment. The decrease in aggregate demand was exacerbated by the restrictive fiscal policy implemented by the government trying to balance the budget. The monetarist explanation concentrates on the behavior of money and asserts that the Fed failed to prevent the collapse of the banking system. The large number of bank failures led to a loss of confidence in the banking system, an enormous increase in the currency-deposit ratio, and therefore a huge decrease in the money multiplier. Monetarists see the resulting severe decline in money supply as the cause of the Great Depression. Both explanations fit the facts and it is important for instructors to point out that there is no inherent conflict between them; in fact, they complement one another.While the programs of the New Deal are largely credited with revitalizing the economy in the mid-1930s, probably one of the most important factors was the sharp increase in money supply, starting in 1933. This is often a forgotten fact. It should be noted that while unemployment remained high, the deflation of prices and wages stopped after 1933, and output began to rebound. In addition, some of the programs implemented by the government after the Great Depression helped to keep wages from falling further.The fact that unemployment’s downward pressure on wages tends to weaken if high unemployment is persistent should also be mentioned at this point. The possibility that the behavior of nominal wages affects the rate of inflation should be discussed with reference to the situation in some European countries, where the unemployment rate has been above the levels experienced in the U.S. for quite some time.The German hyperinflation of 1922-23, when the inflation rate averaged 322% per month, provides another example of a major economic event that shaped macroeconomic thinking. But399students will probably prefer to discuss more recent examples, such as the Bolivian experience of the 1980s highlighted in Box 19-4 or the situation in Zimbabwe starting in 2006. Both cases make clear that the cost of stopping hyperinflation can be extremely high in terms of a decreased standard of living. The discussion should make it clear that large budget deficits and rapid monetary growth are always prevalent in times of hyperinflation, and only draconian measures can ensure a reduction in inflationary expectations. Without such measures the economy will collapse and has to be completely restructured, with the introduction of a new monetary unit that may be pegged to a foreign exchange rate.There is no exact definition of hyperinflation, but it is said to exist when the inflation rate reaches 1,000% on an annual basis. Students will always remember the following definition of inflation in general: “inflation is nothing more than too much money chasing too few goods.” But is inflation “always and everywhere a monetary phenomenon,” as Milton Friedman put it? Figure 19-1 indicates that the rate of inflation and the growth rate of M2 show somewhat similar long-run trends (at least until about 1993), but there are large variations in the short run. In other words, the link between monetary growth and the inflation rate is by no means precise. For one, growth in output affects the inflation rate and real money holdings. Interest rate changes and financial innovations also affect desired money holdings and therefore the income velocity of money. Empirical evidence indicates that the velocity of M2 has shown a fairly constant long-run trend from the 1960s to the 1990s, while the velocity of M1 has fluctuated significantly over the last few decades. Considering the enormous changes that took place in the U.S. banking system in the 1980s, it is surprising that the income velocity of M2 actually stayed as stable as it did. By the late 1990s, the link between M2 growth and the inflation rate had largely broken down; the possible causes and any monetary policy implications should be discussed.By now, students should be familiar with the quantity theory of money equation and should be able to derive the equation that shows the long-run relationship between money growth, output growth, velocity changes, and the rate of inflation. We can thus derive the following:MV = PY ==> %∆M + %∆V = %∆P + %∆Y ==> %∆P = %∆M - %∆Y + %∆V==> π = m - y + v.This equation indicates that higher growth rates of money (%∆M = m) adjusted for growth in output (%∆Y = y) and changes in velocity (%∆V = v) are associated with higher inflation rates (%∆P = π). The strict monetary growth rule is based on this equation and suggests that a zero inflation rate can be achieved if money supply is only allowed to grow at the same rate as the long-run trend of output, assuming that velocity remains stable. It should be made clear, that this equation shows only a long-run relationship and that output growth and velocity can be highly variable in the short run, causing great variations in the inflation rate.Besides looking at the role of monetary growth in determining the inflation rate, instructors may also want to spend some time looking at the role of nominal wages and labor productivity. Just by recalling the simple equationw = W/P,400。
