  11. 11. Inverted Phillips Curve [“Swerve] ”[late 90s] The Crocodile Hunter the Fed Still Listens To Alban William Housego Phillips was a violinist, crocodile hunter, and electrician who became a W.W.II hero. Many say the link between unemployment and inflation has been weakened by technology-driven productivity advances and global competition. [the so-called “ new economy ” ] However, Alan Greenspan still believes in the SRPC trade-off. 97 98 The new economy was really just a favorable supply shock [oil dropping from $26 to $11] and a speedup in productivity.

  14. 14. Phillips “Curl” Unemployment got worse but so did inflation .
  15. 15. Incomes Policies – Wage and Price Controls Wage & price controls were tried & failed during these periods . Diocletion-301; Kublai Khan-13th century; Antwerp-1584; Continental Congress-1775; Nixon-1971; & S. American Countries-1980s. Inflation always won and wage and price controls lost. 1. This produces shortages of products & workers can’t send signals. 2. Price increases show up off the books. 3. Firms convert illegal wage increases ( create new job classifications ) into legal promotions 4. Workers can’t freely bargain for wages 5. The public quickly tires of this . 6. The Market can’t equate QD and QS . 7. Economists reject this approach to reducing inflation. Kublai Khan

  17. 17. Wage-Price Controls To Control Inflation [1971 & 1973 – both failed] President Nixon came into office as a strong opponent of wage-price controls to control inflation . However as inflation edged over 5% in summer of 1971 , he did try it for 90 days . In August of 71, Nixon announced to the nation on a Sunday night (pre- empting “Bonanza”) , the 90 day freeze on wages. Nixon hoped he would not be perceived as a flip-flopper on this issue. The next day, 90% of the next day’s news were devoted to this issue. The DOW liked the news and shot up 33 points , as Nixon was perceived as “acting boldly” , and coming to the defense of the consumers against the “price gougers” . He also did it again in 73 but it didn’t work any better. His head of the OMB told him that they had convinced the public of their original position that, “wage & price controls don’t work to control inflation.” P rotesters against the N ixon Wage f reeze So-do wage & p rice c ontrols work to control inflation?

  22. 22. Reaganomics The core of the supply-side theory was that lower marginal tax rates would cause people to “supply” more labor , working more and harder, which would increase growth – and the positive effect on growth would be so large that “G” tax revenue would actually increase rather than decrease in response to the tax cut. [Ave. 23% cut] “ I was on the Laffer curve.”
  23. 23. 0 100 m m n l THE LAFFER CURVE Tax revenue (dollars) Tax rate (percent) Maximum Tax Revenue President Reagan said he was on the Laffer curve. He said that after WW II , when he started making big money, that he could do 4 movies before hitting the top marginal tax rate of 90%. After 4, because he could only keep 10%, he would quit making movies until the next year. “ Yes, I was on the Laffer cuve. I couldn’t shoot my way out” The “Gipper” Bonzo For rich people , there would be a disincentive to quit working when they hit the top marginal tax rate. For most workers , this was not the case .

  24. 24. Comparing the Laffer Curve to Robin Hood <ul><li>Arthur Laffer illustrated his supply-side views with a story relating to Robin Hood , who stole from the rich to give to the poor . Laffer likenedpeople traveling through Sherwood Forest to taxpayers , whereas Robin Hood and his band of merry men were government . As taxpayers passed through the forest, Robin Hood and his men intercepted them and forced them to hand over their money. Laffer asked audiences, “Do you think that travelers continued to go through Sherwood Forest?” </li></ul>His answer was, “No.” Taxpayers will avoid Sherwood Forest to the greatest extent possible. They will lower their taxable income by reducing work hours, retiring earlier, saving less, and engaging in tax avoidance and tax evasion activities. Robin Hood and his men may end up with less revenue than if they collected a relatively small “tax” from each traveler for passage through the forest. The “rich” Sherwood Forest Robin Hood
