First of all, it needs to be clear that the definition of "most difficult" may vary from person to person. Everyone's feeling of "difficulty" may depend on their own background, interest, learning style and other factors.
At the same time, different majors will involve different disciplines and technologies, and each technology has its own difficulties. However, among ordinary economists, econometrics and macroeconomics are usually considered as difficult fields to learn.
Econometrics is a branch of economics, which specializes in how to use mathematical and statistical methods to analyze and predict economic phenomena. It covers advanced mathematical concepts, such as linear algebra, probability theory and statistics.
For students with weak mathematical foundation, econometrics may become a challenge. In addition, econometrics also needs a deep understanding and processing ability of economic data, which is also a difficult point.
Macroeconomics is a discipline that studies the overall economic operation, including economic growth, inflation, unemployment and other issues. It involves complex concepts and indicators such as gross national product (GDP), inflation rate and unemployment rate. Macroeconomics also involves dynamic optimization, monetary policy, fiscal policy and other advanced technologies, which may be challenging for many beginners.
In addition to econometrics and macroeconomics, other challenging economics majors include financial economics, environmental economics and international economics.
Financial economics studies the operation of financial markets and the pricing of financial products. It needs to understand complex financial instruments and trading strategies, such as derivatives, options and futures. Financial economics also involves advanced technologies such as stochastic process, option pricing and risk management.
Environmental economics is to study the economic impact of environmental problems and how to deal with them through economic means. It involves complex issues such as sustainable development, environmental policy and climate change, and needs to know a lot of policies and data.
International economics is a discipline that studies international trade, international finance and global economic operation. It needs to understand complex international trade agreements, international financial markets and global economic trends. International economics also involves complex concepts and technologies such as exchange rate, balance of payments and international trade policy.
It is very important for candidates who want to become economists to choose a major that suits them. Different majors will have different difficulties, but as long as you have a solid foundation in economics, study hard and understand deeply, you can master these professional knowledge. At the same time, taking part in training courses, doing problems and simulating exams are also effective ways to improve learning efficiency and pass exams.
