<div class="text-justify">Greetings colleague continuing to share content from the world of Economics, we know that macroeconomics is the focus of the economy that studies the most aggregated variable in the economic world, such as GDP, this variable is a very important indicator for any economy, this variable refers to the monetary value of the production of goods and services of final demand of a country or region during a determined period, normally one year than the fiscal year.

<br>PIB reader friend allows us to identify failure in the economic models applied in an economy, to solve or respond to the scarcity law, and also allows us to know if all internal production of a nation complies with the demands of its society, because having account there are goods and services, not everything is produced, it is necessary to compare it outside the internal economy, we must be careful with the following when buying most goods and services, taking into account that it can produce, that creates inflation and a flight of capital or of national income to activate the economy and its factors of production. PIB measures only final production and not so-called intermediate production, in order to avoid double counting, something very important to refer to final goods and services.

<br> This is a nominal value at current price of goods and services, also a real value at constant price, within these variables we can find the following in the valuation at market prices is carried out including indirect taxes and subsidies to the exploitation. What is unique about everything is how in the economic world these variables do not allow us to know savings, investment and the trade balance. They are three flow magnitudes that satisfy a very simple identity in the requirement of a country's need for society.

<br> Another way to see if there was a good entrance of national income is thanks when the rate of variation of the GDP increases, that is, the PIB of the calculated year is greater than that of the previous year, because the current year reference is taken with Previously, the same is done with unemployment, inflation that are also macroeconomic variables, this variable in a country is divided into different states or provinces, to then determine the gross domestic territorial production, thus the analysis of economic development for each region is included.
