Fundamental Analysis

Fundamental Analysis. Classical vs. Keynesian. Similarities. Both the classical approach and the Keynesian approach are macro models and, hence, examine the interaction between asset, money, and labor markets. Both models depend on the “fundamentals” (GDP, price levels, etc).

  1. Fundamental Analysis Classical vs. Keynesian

  2. Similarities • Both the classical approach and the Keynesian approach are macro models and, hence, examine the interaction between asset, money, and labor markets. • Both models depend on the “fundamentals” (GDP, price levels, etc)

  3. Classical Analysis Keynesian Analysis Differences

  4. Classical Analysis Prices are flexible, markets clear Money is “Neutral” Emphasis on Relative Prices Asset markets play a minor role Emphasis on Technology rather that policy (Supply side) Keynesian Analysis Differences

  5. Classical Analysis Prices are flexible, markets clear Money is “Neutral” Emphasis on Relative Prices Asset markets play a minor role Emphasis on Technology rather that policy (Supply side) Keynesian Analysis Prices are fixed in the short run Money can influence output in the short run (Phillips curve) Asset markets play a pivotal role Emphasis on policy rather than technology (demand side) Differences

  6. Example: The Productivity Slowdown • During the Mid 1970’s, productivity growth dropped from its long run average of 1.5% to -.27%.

  7. Classical Analysis • How would this drop in productivity influence capital markets?

  8. Classical Analysis • How would this drop in productivity influence capital markets? • Investment demand would most likely drop as firm’s face lower profit expectations.

  9. Classical Analysis • How would this drop in productivity influence capital markets? • Investment demand would most likely drop as firm’s face lower profit expectations. • Lower productivity ,means shrinking personal income. What happens to personal savings?

  10. Classical Analysis • How would this drop in productivity influence capital markets? • Investment demand would most likely drop as firm’s face lower profit expectations. • Lower productivity ,means shrinking personal income. What happens to personal savings? • Temporary drop in income tends to lower savings • Permanent declines in income tend to lower consumption

  11. Classical Analysis • Recall that at a (fixed) global interest rate, the current account balance is the difference between domestic savings and domestic borrowing (public and private)

  12. Classical Analysis • Suppose that, initially trade was balances at the global interest rate of 10%.

  13. Classical Analysis • Suppose that, initially trade was balances at the global interest rate of 10%. • A drop in investment demand in a closed economy would lower the domestic interest rate • In an open economy, the economy runs a trade surplus

  14. Classical Analysis • How would this drop in productivity influence money markets?

  15. Classical Analysis • How would this drop in productivity influence money markets? • Recall, the demand for money is equal to M = kPY • A drop in income (Y) without a corresponding drop in money supply creates rising prices

  16. Classical Analysis • What happens to real/nominal exchange rates?

  17. Classical Analysis • What happens to real/nominal exchange rates? • Recall, P=eP* (PPP) • Assuming no change in the foreign price level, a rise in the domestic price level causes an equal rise (depreciation) in the nominal exchange rate • PPP implies a constant real exchange rate

  18. Summary • Current account improves • No change in domestic (real) interest rates • A rise in the domestic price level • A depreciation in the nominal exchange rate • A constant real exchange rate

  19. Keynesian Analysis • As before, begin in capital markets. • Investment drops while savings remains constant • With excess demand for credit, interest rates fall and income falls (lower income lowers savings) – IS shifts left

  20. Keynesian Analysis • The shift in IS reflects two opposing forces in the balance of payments:

  21. Keynesian Analysis • Lower income improves the current account, but lower interest rates worsen the capital account

  22. Keynesian Analysis • With a high rate of capital mobility, the interest rate effect dominates and a BOP deficit results • A BOP deficit forces a currency depreciation

  23. Keynesian Analysis • We know that the long run impact is a currency depreciation • However, lower domestic interest rates imply a future currency appreciation (Interest Parity)

  24. Keynesian Analysis • We know that the long run impact is a currency depreciation • However, lower domestic interest rates imply a future currency appreciation (Interest Parity) • Therefore, the initial currency depreciation must be larger than the long run result (overshooting)

  25. Summary • Current account improves (by more in the short run due to the sharp depreciation) • Domestic real interest rates fall • No change in domestic prices • A sharp depreciation (both real and nominal) followed by an appreciation

  26. Savings: 1970-1980

  27. Consumption: 1970-1980

  28. Investment: 1970-1980

  29. Interest Rates: 1970-1980

  30. Current Account: 1970-1980

  31. GDP: 1970-1980

  32. Prices: 1970-1980

  33. Exchange Rate: 1970-1980

  34. Example: Government Deficits • Currently, the US deficit is around $500B dollars (projected to be $550B in 2004)

  35. Classical Analysis • Suppose that the government runs a $500B deficit

  36. Classical Analysis • Suppose that the government runs a $500B deficit • A rise in demand for loanable funds increases the interest rate

  37. Classical Analysis • Suppose that the government runs a $500B deficit • However, with higher anticipated future taxes, households increase their savings

  38. Classical Analysis • Suppose that the government runs a $500B deficit • These two effects offset each other, leaving savings, investment, and the interest rate unchanged.

  39. Summary • The current account is unaffected as are domestic interest rates • Assuming that the deficit has no effect on GDP, money markets are unaffected leaving prices and exchange rates (real and nominal) unchanged.

  40. Keynesian Analysis • Suppose that the government deficit increases. • The long run impact should be zero.

  41. Keynesian Analysis • However, in the short run, the IS curve shifts right – output increases and interest rates rise. • In this example, the worsening of the trade deficit is more than offset by higher interest rates attracting foreign capital. A balance of payments surplus is created.

  42. Summary • In the short run, a BOP surplus is created causing a currency appreciation • However, interest parity suggests that higher domestic interest rates imply a currency depreciation
