I have a master's degree in mathematics and worked as a teacher for two years after graduation. I want to take a cross-disciplinary examination for my doctorate, which is better, economics or finance? Help! Don't even think about it It must be a financial exam. Economics is a specialized study of theory. If you like doing research, you can study economics when you work in universities and research institutes in the future. But finance is more practical, and employment is very good. Not to mention a doctor of finance, 200,000 to 300,000 a year is definitely no problem.
