1. The Global Recession The Global Recession. World GDP Growth, 2007-2010. Emerging market countries hoped that they could avoid a similar fate, that there would be in effect decoupling between advanced countries and emerging market countries. As Figure 1 shows, these hopes were dashed.

2. The Global Recession From early 2007 to the end of 2008, stock prices lost more than half of their value. While they have recovered, they are still far below their peak. Stock Prices and the Recession, 2007-2009.

3. The Trigger. U.S. House Price declines Housing prices increased sharply from 2000 to 2006, only to decline, equally sharply, from 2006 on. U.S. housing prices, 2000-2009.

4. The Trigger. U.S. House Price declines These developments were much less benign than most economists thought. First, housing prices could go down. Second, in many cases, the mortgages were in fact much riskier than either the lender pretended, or the borrower understood. The estimated output cost of the crisis is around $30 trillion, roughly 1/2 of annual world GDP, and 100 times the initial mortgage losses! While the trigger was the U.S. housing price decline, its effects were enormously amplified.

10.  When housing prices declined, and some mortgages went bad  High leverage implied a sharp decline in the capital of banks.  This forced them to sell some of their assets that were often hard to value.  They had to sell them at very low prices—often referred to as re sale prices.  The complexity of the securities (MBSs, CDOs) and of the true balance sheets of banks (banks, and their SIVs) made it very difficult to assess the solvency of banks, and their risk of bankruptcy.  Interbank lending froze.  On September 15, 2008, Lehman Brothers, a major bank with more than $600 billion in assets, declared bankruptcy.  Leading financial participants concluded that many, if not most, other banks and financial institutions were indeed at risk.  These guys knew the shape they themselves were in...if they couldn’t trust themselves, how could they trust counterparties???  INTERBANK LENDING FROZE Amplification Mechanisms. Leverage, Complexity, and Liquidity

12. Amplification mechanisms The rate spread, which reflects the risk banks perceived in lending to each other, went sharply up in September 2008. The Ted Spread, 2007-2009. Banks became very reluctant to lend to each other. The TED Spread: The difference between the riskless rate (measured by the rate of 3-month government bonds) and the rate at which banks are willing to lend to each other (known as the Libor rate...which we now know was understated!)

23. According to your textbook, the built-in mechanism that can lift economies out of recessions is this: – Output below the natural level of output leads to lower inflation. – Lower inflation leads in turn to higher real money growth. – Higher real money growth leads to an increase in output over time. (M/P) up  i down  I up  Y up…until full employment restored This mechanism, however, is not foolproof. Disinflation, Deflation, and the Liquidity Trap

24. A Long Slump Spending decisions depend on real interest rate Demand for real balances depends on nominal rate When inflation decreases in response to low output, there are two effects: (1) The real money stock increases, leading the LM curve to shift down, and (2) expected inflation decreases, leading the IS curve to shift to the left. The result may be a further decrease in output. The Textbook Effects of Lower Inflation on Output

25. A Long Slump The Liquidity Trap When the nominal interest rate is equal to zero, and once people have enough money for transaction purposes, they become indifferent between holding money and holding bonds. The demand for money becomes horizontal. This implies that, when the nominal interest rate is equal to zero, further increases in the money supply have no effect on the nominal interest rate. Money Demand, Money Supply, and the Liquidity Trap

26. A Long Slump: Liquidity Trap and Deflation In words: The economy caught in a vicious cycle: Low output leads to more deflation. More deflation leads to a higher real interest rate and even lower output, and there is nothing monetary policy can do about it. In the presence of a liquidity trap, there is a limit to how much monetary policy can increase output. Monetary policy may not be able to increase output back to its natural level. Suppose the economy is in a liquidity trap, and there is deflation. Output below the natural level of output leads to more deflation over time, which leads to a further increase in the real interest rate, and leads to a further shift of the IS curve to the left. This shift leads to a further decrease in output, which leads to more deflation, and so on. The Liquidity Trap and Deflation

30. Negatively sloped AD: Inflation down  Burden of debt on debtors up  They spend less  Wealth of creditors up  but they’re not spenders

33. Topsy Turvy Economics: Debt Deflation at Zero Lower Bound Monetary stimulus doesn’t matter when interest rate on bonds is zero: Currency Up but Deposits Down  M up a little H up $GDP unaffected or down Reserves Up  Bank Credit Down It’s like “pushing on a string” Paradox of thrift: Deleveraging: S up  Y down  P down  (M/P) up... But i can’t fall so no recovery Paradox of deleveraging: Fire sale of assets only lowers their prices  Deflation The more debtors pay the more they owe. Perverse Aggregate Demand (upward sloping: falling price reduces spending) Debtors can’t spend and creditors won’t spend (unless real interest rate is negative) Paradox of toil: Increased supply drives down price and reduces output and employment Paradox of flexibility: The more wages and prices fall in slump, the worse things get Prescriptions: Fiscal stimulus Increased gov’t debt  inflationary expectations Central bank commitment to irresponsible stance  inflationary expectations Debt forgiveness: principal reductions

34. Has potential real GDP shifted downward? Prolonged unemployment  loss of skills Then we’re not in a slump...get used to it...But we got back on track after the Great Depression It took WWII  High employment/learning scientific breakthroughs...is there a lesson here?

38. The robust growth that Japan had experienced since the end of World War II came to an end in the early 1990s. Since 1992, the economy has suffered from a long period of low growth—what is called the Japanese slump. Low growth has led to a steady increase in unemployment, and a steady decrease in the inflation rate over time.

Why did it last so long? Were monetary and fiscal policies misused, or did they fail? What are the factors behind the modest recovery?

42. The Rise and Fall of the Nikkei The increase in stock prices in the 1980s and the subsequent decrease were not associated with a parallel movement in dividends. Stock Prices and Dividends in Japan since 1980 The fact that dividends remained flat while stock prices increased strongly suggests that a large bubble existed in the Nikkei. The rapid fall in stock prices had a major impact on spending—consumption was less affected, but investment collapsed.

43. Fiscal policy was used as well. Taxes decreased at the start of the slump, and there was a steady increase in government spending throughout the decade. Fiscal policy helped, but it was not enough to increase spending and output. The Japanese Slump The Failure of Monetary and Fiscal Policy

44. Government spending increased and government revenues decreased steadily throughout the 1990s, leading to steadily larger deficits. Government Spending and Revenues (as a percentage of GDP) in Japan since 1990 Output growth has been higher since 2003, and most economists cautiously predict that the recovery will continue. This raises the last set of questions. What are the factors behind the current recovery? There appear to be two main factors. A Regime Change in Monetary Policy The Cleanup of the Banking System
