Federal Open Market Committee conducts monetary policy by controlling the money supply. The money supply is the quantity of money available in the economy. The primary way in which the Fed changes the money supply is through open-market operations. The Fed purchases and sells U.S. government bonds. To increase the money supply, the Fed buys government bonds from the public. To decrease the money supply, the Fed sells government bonds to the public.3. The Phillips curve shows the short-run combinations of unemployment and inflation that arise as shifts in the aggregate demand curve move the economy along the short-run aggregate supply curve. The Phillips curve seems to offer policymakers a menu of possible inflation and unemployment outcomes. As a result, the long-run Phillips curve is vertical at the natural rate of unemployment. Monetary policy could be effective in the short run but not in the long run. In the long run, expected inflation adjusts to changes in actual inflation.4. Job search, this unemployment is different from the other types of unemployment. It is not caused by a wage rate higher than equilibrium. It is caused by the time spent searching for the “right” job. Minimum wage laws, although minimum wages are not the predominant reason for unemployment in our economy, they have an important effect on certain groups with particularly high unemployment rates. When the minimum wage is set above the level that balances supply and demand, it creates unemployment. Unions, a union is a worker association that bargains with employers over wages and working conditions. In the 1940s and 1950s, when unions were at their peak, about a third of the U.S. labor force was unionized. A union is a type of cartel attempting to exert its market power. Efficiency wages, Efficiency wages are above-equilibrium wages paid by firms in order to increase worker productivity. The theory of efficiency wages states that firms operate more efficiently if wages are above the equilibrium level.Part3:1.
