Economics is the study of scare resources. What should we produce? How should we produce? For whom and when should we produce? These economic questions is the foundation in basic courses in economics.
When you study economics you will use theoretical analyses to get a picture of how the economy works and how it can change. If you continue to study on an intermediate level you can choose courses in for example industrial economics, financial economics or environmental economics. On advanced level we have courses in for instance health economics.
There are many research areas in economics. Some examples are public economics, environmental economics and labor economics. The research can be theoretical or empirical.
Economics can be chosen as a major subject within several different programmes and is a smaller part of several others. You can also read economics as freestanding courses. There is a Master's programme if you aiming for a Master's degree in economics.
