employment• Analyzed in terms of Aggregate Demand and

Aggregate Supply. AD depends on IS-LM, which is a major building block. (also, IS*-LM*)

Epilogue to Mankiw text

Four most important lessons of macroeconomics. 1.    In the long run, a country’s capacity to produce goods and services determines the standard of living of its citizens. 2.    In the short run, aggregate demand influences the amount of goods that a country produces 3.    In the long run, the rate of money growth determines the rate of inflation, but does not affect the rate of unemployment 4.    In the short run, policymakers who control monetary and fiscal policy face a tradeoff between inflation and unemployment

The four most important unresolved questions in macro

1.  How should policymakers try to raise the economy’s natural rate of output? 2.   Should policymakers try to stabilize the economy? 3.   How costly is inflation, and how costly is reducing inflation? 4. How big a problem is government debt?

Note that the US currently suffers a recession, a large short term deficit, and the prospect of high long term debts.
