Petroleum economics is a complicated series of political and economic interactions pertaining to the oil industry. While economics in general is a complex subject, in the case of oil, political concerns add a new layer to the study of economics. People who study petroleum economics need to be familiar with economics generally, but also geopolitical history and the history of the oil industry as a whole. Experts in this field can work for government agencies, oil companies, and private companies interested in the economics of oil production, transport, and refining.
As with economics in general, there are a number of approaches to petroleum economics. Many experts boil down economic activities to a balance between supply and demand. In this case, supply and demand are both influenced by political concerns. Political events can have an impact on oil supply as well as demand, and in turn, oil supply and demand can influence politics.
There are a number of theories to describe economic phenomena in the oil industry, as well as to explore political relationships and social phenomena. This branch of economics also includes a broad number of connected fields, including international shipping, agriculture, manufacturing, transport, and so forth. Understanding of these fields is important, as all of these industries are involved in the global demand for oil.
People interested in this subject study a wide variety of topics, from theories about global oil availability in the future to the environmental costs associated with oil and gas production. They can apply their studies to shaping oil and gas policy, assisting companies with the development of new oil fields, and educating people interested in the economies and politics of oil-producing nations. Alternative energy is also a topic of study for some people in this field, as they are interested in the political push for the development of alternatives to oil, as well as the economic impacts of shifting energy supplies.
Colleges and universities all over the world offer coursework in petroleum economics, and in some cases, provide students with degrees in this field. Many people working in the subject have graduate degrees and have conducted research in this field. Discussions of the oil industry can be found everywhere from the pages of confidential government briefings to the front page of the newspaper, and there are ample employment opportunities available to experts in this particular area of economics.
