17. Monetary Policy in Practice Fed policy and the output gap Taylor Rule (setting the Fed Funds Rate that takes into account both inflation rate and output gap) Fed Funds Rate = 1 + (1.5 x inflation rate) + (0.5 x output gap) OR 1+(1.5 X π%)+(0.5 X Output Gap) Stanford Economist, John Taylor

18. Inflation Targeting Inflation Targeting The Fed and Inflation (prefers inflation of about 2%) Inflation Targeting (used by “other” central banks— more accountability and transparency—everyone knows the goal and if the bank doesn’t succeed, it comes under scrutiny) Inflation Targeting v. Taylor Rule (Infl Targ more forward-looking than backward-looking as the Taylor Rule) Inflation Targeting v. Fed discretion
