Applied Fields of Economics
There is a basic theory and factors in economics in which all economists are interested. However, economics has some main applied fields that deal with specific topics such as industrial, agricultural economics, economics of energy, economics of education, labour economics, etc.
Industrial organization and structure are studied by the industrial economics which also analyzes markets for manufactured goods as well as policies of various enterprises. The degree of concentration and barriers against new competitors in the market have already been analyzed by industrial economics for such important branches of economy as mining, gas and oil industries, etc. The firms and companies’ operation in an industry is influenced by the structure of the industry itself. Both profits and losses in any industry also are affected by the behaviour of firms and companies engaged in the industry.
The economics of energy is known as another important field of applied economics, and it is closely connected with the industrial economics. A lot of energy has been used by modern economy in recent decades. Farms, factories, plants, transport as well as domestic needs consumption have greatly increased the consumption of energy since new modern equipment and technologies have been introduced.
In the past wood and coal were used as the main sources of energy. Then these sources were replaced by gas and oil, in most industries. However, in the 1970s energy sources became scarce and there was a rise in energy prices. Since that time serious adjustments have been made by industrial economics in order to cope with energy scarcity.
For the last few decades the problems of energy economics have been discussed by specialists and governments in many countries. Regular meetings are held by the OPEC formed to regulate oil prices.
