True or false:
1. Frictional unemployment, while not good in itself, is a by-product of a healthy phenomenon; and because it is short lived, it is not generally viewed as a serious problem.
2. Structural employment can arise because jobs that require particular skills disappear.
3. Structural unemployment is easily measured and stable over time.
4. Cyclical unemployment may result from an insufficient level of demand for goods and services.
5. Given the volatility and dimensions of unemployment, governments view it as the result of inadequate demand, which is especially correctable through government policies.
6. The natural rate of unemployment roughly equals the sum of frictional and cyclical unemployment when they are at a maximum.
7. When unemployment rises above the natural rate, it reflects the existence of cyclical unemployment.
8. The natural rate of unemployment does not change over time.
