what is price level 
price level is the average of current prices across the entire spectrum of goods and services produced in an economy in more general terms price level refers to the price or cost of a good service or security in the economy price levels may be expressed in small ranges such as ticks with securities prices or presented as a discrete value such as a dollar figure in economics price levels are a key indicator and are closely watched by economists they play an important role in the purchasing power of consumers as well as the sale of goods and services it also plays an important part in the supply demand chain understanding price levelthere are two meanings of the term price level in the world of business the first is what most people are accustomed to hearing about namely the price of goods and services or the amount of money a consumer or other entity is required to give up to purchase a good service or security in the economy prices rise as demand increases and drop when demand decreases the movement in prices is used as a reference for inflation and deflation or the rise and fall of prices in the economy if the prices of goods and services rise too quickly when an economy experiences inflation a central bank can step in and tighten its monetary policy and raise interest rates this in turn decreases the amount of money in the system thereby decreasing aggregate demand if prices drop too quickly the central bank can do the reverse loosen its monetary policy thereby increasing the economy s money supply and aggregate demand the other meaning of price level refers to the price of assets traded on the market such as a stock or a bond which is often referred to as support and resistance as in the case of the definition of price in the economy demand for a security increases when its price drops this forms the support line when the price increases a sell off occurs cutting off demand this is where the resistance zone lies price level in the economyin economics price level refers to the buying power of money or inflation in other words economists describe the state of the economy by looking at how much people can buy with the same dollar of currency the most common price level index is the consumer price index cpi the price level is analyzed through a basket of goods approach in which a collection of consumer based goods and services is examined in aggregate changes in the aggregate price over time push the index measuring the basket of goods higher weighted averages are typically used rather than geometric means price levels provide a snapshot of prices at a given time making it possible to review changes in the broad price level over time as prices rise inflation or fall deflation consumer demand for goods is also affected which leads to changes in broad production measures such as gross domestic product gdp price levels are one of the most watched economic indicators in the world economists widely believe that prices should stay relatively stable year to year so that they don t cause undue inflation if price levels rise too quickly central banks or governments look for ways to decrease the money supply or the aggregate demand for goods and services although prices change gradually over time during inflationary periods they can change more than once a day when an economy experiences hyperinflation price level in the investment worldtraders and investors make money by buying and selling securities they buy and sell when the price reaches a certain level these price levels are referred to as support and resistance traders use these areas of support and resistance to define entry and exit points support is a price level where a downtrend is expected to pause due to a concentration of demand as the price of a security drops demand for the shares increases forming the support line meanwhile resistance zones arise due to a sell off when prices increase once an area or zone of support or resistance is identified it provides valuable potential trade entry or exit points this is so because as a price reaches a point of support or resistance it will do one of two things bounce back away from the support or resistance level or violate the price level and continue in its direction until it hits the next support or resistance level
