Money Growth and Inflation
The principle of monetary neutrality asserts that changes in the quantity of money influence nominal variables but not real variables. One application of monetary neutrality is the Fisher effect: when the inflation rate rises, the nominal interest rate rises by the same amount so that the real interest rate remains the same.

Unemployment
The labor force is the total number of workers, including both the employed and the unemployed. The unemployment rate is the percentage of those who would like to work and do not have jobs. Frictional unemployment is inevitable simply because the economy is always changing. Unemployment insurance, while reducing the hardship of unemployment, increases the amount of frictional unemployment. The unemployment that results because the number of jobs available in some labor markets is insufficient to provide a job for everyone who wants one is called structural unemployment, which is often thought to explain longer spells of unemployment.

At he broadest level, the financial system moves the economy’s scarce resources from savers to borrowers. Savers supply their money to the financial system with the expectation that they will get it back with interest at a later date, while borrowers demand money from the financial system with the knowledge that they will be required to pay it back with interest at a later date.

Measuring the Cost of Living
The consumer price index (CPI) is a measure of overall cost of the goods and services bought by a typical consumer. When the CPI rises, the typical family has to spend more money to maintain the same standard of living. The inflation rate is the percentage change in the price index from the preceding period. When the inflation rate rises, the economy’s overall price level is rising. The producer price index (PPI) measures the cost of a basket of goods and services bought by firms rather than consumers. Because firms eventually pass on their costs to consumers in the form of higher consumer price, changes in the PPI are often thought to be useful in predicting changes in the CPI. Continue reading
