Answer to Question 1

The substitution bias causes the CPI to overstate inflation and the cost of living because the CPI, being based on a fixed market basket of goods and services, implicitly assumes that consumers do not switch away from products whose prices are rising and into products whose prices are falling (or rising less). Consumers dodge some price increases by switching to other products, therefore decreasing their cost of living below what the CPI indicates.
The increase in quality bias causes the CPI to overstate inflation and the cost of living because a portion of the price increase of many goods and services is due to an increase in quality. The Bureau of Labor Statistics tries to filter out the portion of the price increase due to quality, but does not fully adjust the price increase for quality improvements.
