Macroeconomics

Concepts of Macroeconomics

The aspect of macroeconomic is widely studied in close relation to the microeconomics since these are factors that relate closely and often affect each other in the economic sense of it. Macroeconomics can be described as the branch of economics that deals with structure, performance and behavior of a regional or national economy in totality. It is mostly concerned with the aggregate indicators like the unemployment rates, price indices and GDP in order to grasp the function of the whole economy of the region. It also develops models that help in the explanation of the relationships between economic factors like the consumption, national income, unemployment, output, inflation, investment, saving, international finance and international trade.

There are basic indicators of macroeconomics which can be used to the macroeconomic levels of a given region. These will help in the explanation of the stagflations whenever they happen and can also be used in the prediction of stagflation. Economic growth is one of the factors of macroeconomics. The increase in the economic activities if often measure through the use of the GDP and it is noted that negative growth is one of the major indicators of economic depression and economic recession hence can be used to predict the occurrence of such events.

Gross national product is yet another indicator of macroeconomics this is the value of the output in terms of goods and services that are received by a country in a year as well as the income received in a year by the people who reside within the country in one year. The capital invested abroad is also included in this bracket. This is where the use of rationality can be effectively used to make better predictions as compared to the historical facts according Krugman P., (2014) since these incomes and capital investments abroad will always change and shift accordingly.

National income is also a factor of macroeconomics and refers to the total value of goods and services that has been produced by the citizens of a given region or country over a given period of time, often a year. This is where the use of historical experiences can be of great importance since it can be practically impossible to expect a double national income digits just one or two years down the line hence even stagflation can be predicted to last a given period using this approach.

Inflation is yet another important indicator of macroeconomics and it can be referred to as the sustained increase in prices of services and goods over a given period of time. As the argument posted in the article by Krugman P., (2014) that preemptive pricing has been fronted by some as a measure to check the inflation, it is evident that this will only help heighten the inflation instead.
