GDP

What does GDP measure and is it an accurate macroeconomic indicator?

GDP - Gross Domestic Product measures the wealth of a country according to the amount that is produced and consumed in the market.  It only measures actions if they affect the economic market, such as buying goods or working for an employer.  It takes into account inflation, but does not measure the amount of polution, happiness and demolition.  It does not have a  moral compass, it is just a number, a statistic.  Because of this, it is a macroeconomic indicator, because from a standpoint of looking at the affects of choices, GDP is merely a number and constitutes scarcity or incentives.  It is the choices of buying or selling that creates the GDP, however a decision or many descisions cannot be isolated from the GDP.
