Income and fertility
Gross domestic product (GDP) is the total dollar value of all goods an economy produces over a given time, usually expressed as a comparison to the previous quarter or year. If the year to year GDP is up 5 percent, then the economy has grown 5 percent. There are two approaches - the income approach (adding up all earnings over a year) and the expenditures approach (adding up what everyone spent). The income approach is described as the total employee compensation, gross profit for corporations and non-incorporated firms, and taxes minus subsidies. The expenditures method is more common and it specifically combines total consumption within households, and the total investment within a business. It also reveals how much money the government is spending and the balance of trade. Another factor by which is not promptly supportive are the youngsters who play a role within GDP. They clearly do not add to it and do not help the stock and bond market returns. Youngsters are wellsprings of advancement, entrepreneurial souls and play a major incentive to GDP.
Economic integration
Dynamic analysis has started with a new definition of gross domestic product (GDP), as a difference between aggregate revenues of sectors and investment (a modification of the value added definition of the GDP). It was possible to analytically prove that all the states gain from economic unification, with larger states receiving less growth of GDP and productivity, and vice versa concerning the benefit to lesser states. Although this fact has been empirically known for decades, now it was also shown as being mathematically correct.
