After all in a market economy money must be earned. To earn money means that an individual must produce something that can be exchanged for money. Once money is earned it then can be exchanged for goods and services. In other words earning money precludes the possibility of consuming without producing first. From this we can infer that what causes general rise in prices is increases in the money stock.
Inflation is seen by most individuals as bad news.
For, it is seen as undermining people's living standards through the erosion of real incomes. For if inflation is a general rise in prices then we must conclude that a rise in prices undermines people's living standards. Careful analysis of this issue will show that a rise in prices doesn't as such undermine people's living standards. Prices are the manifestation of people's valuation of goods in terms of money. The act of valuing however, cannot alter these goods.
