Macroeconomics is the sum total of economic activity, dealing with the issues of growth, inflation, and unemployment. It concerns the effects of national economic policies, an example of which is taxation rates and application, on the national economy. Macroeconomics is based on assumptions in microeconomics. Gross domestic product is an economic statistic describing the monetary value of all the finished goods and services produced within a country’s borders.

It describes the relationship between price levels and the quantity of output that producers are willing to provide. The higher the demand the higher the price.
