Economics will help you understand human incentives as well as those of the financial markets. Together these will broaden your perspective of the business as a whole. You will be able to appreciate the economy more holistically than ever before.
An economics degree by itself can help you get banking, finance, or consulting jobs. You can expect wages close to the average salary in your country. However, most of these jobs are not considered to be high paying ones.
By taking additional stats, econometrics, maths, and modelling courses you can upgrade your quantitative and critical thinking skills. These skills will make you employable in a number of new fields.
You will have access to more senior-level positions and get opportunities in data analysis, supply chain, and research. Strong quantitative skills are a must for such positions.
The sheer flexibility in selecting your advanced courses can open up so many avenues for you. For instance, by taking behavioural economics, economic policy, and economic law can you can be hired as an economic strategist.
