## Inflation

• ### Forecasting the 2007 recession

After the introduction to economic indicators in section : macroeconomic forecasting through economic indicators, this section will look at the possibilities of predicting the recession starting in December 2007 using these indicators. Again it is important to remember that as this paper is written ex. post with revised data and a broad understanding of what went wrong1, it could easily be pointed at numerous of relatively detailed and complicated indications that something was fundamentally wrong with the US economy ahead of the recession.

• ### Inflation: Causes, Costs, and Current Status

Since the end of World War II, the United States has experienced almost continuous inflation— the general rise in the price of goods and services. It would be difficult to find a similar period in American history before that war. Indeed, prior to World War II, the United States often experienced long periods of deflation. It is worth noting that the Consumer Price Index (CPI) in 1941 was virtually at the same level as in 1807.

### Galloping and creeping inflation

In the summer of 1923, the German inflation was rapidly heading toward the grand finale: total repudiation of the currency. As an instructor in a Berlin college, this writer drew a monthly salary that had been raised from an inflated 10,000 marks or so in early 1922 to 10,000,000 marks by July, 1923, and the whole amount was being paid twice a month; then, once every week; then once each day.

### Price level

Prices are of great importance in macroeconomics as indeed they are in microeconomics. However, in microeconomics we are more interested in prices of individual goods and services and such prices are rarely important for the economy as a whole although there are exceptions (for example, the price of oil).

In macroeconomics we are more interested in how prices change on average . We define the price level as a weighted average of several different prices. If p 1 is the price of gasoline and p 2 the price of oil, then 10 p 1 + p 2 is a price level. It is a weighted average of two prices with weights 10 and 1. Normally, the price level is defined using many more prices.

• ### The Modus operandi of inflation

Money originates in one of two ways. One way is by depositing gold, the value of which is credited to the depositor on a bank account. However, the bulk of the nation's "purchasing power" stems from credit extended by banks,! be it by loaning funds or by purchasing securities (bonds).

• ### What Is Inflation?

It may be one of the most familiar words in economics. Inflation has plunged countries into long periods of instability. Central bankers often aspire to be known as “inflation hawks.” Politicians have won elections with promises to combat inflation, only to lose power after failing to do so.
