### Course description and aims

With microeconomics, macroeconomics is one of the most fundamental fields in economics, dealing with the aggregated economic variables such as GDP, unemployment rate, price index, and so on.

This course provides a basic view of macroeconomics at the undergraduate level. The first half of this course covers measurement of macroeconomic activity, households' consumption-saving behavior, firms' production-investment behavior, and the role of financial asset markets and money. Then, the second half focuses on how major macroeconomic variables are determined in both long-run and short-run equilibria. We also discuss the effectiveness of fiscal and monetary policies.

The aim of this course is twofold. First, students can precisely explain the definitions of the aforementioned major macroeconomic variables which they roughly know through newspapers and evening news. Second, they can construct a simple mathematical model to analyze the mechanics of how the variables are determined.

### Student learning outcomes

By the end of this course, students will be able to:
1) Using the definitions, calculate major macroeconomic variables, including GDP, inflation rate, unemployment rate, current account, etc.
2) Understand how decisions made by economic agents (e.g., households and firms) determine such macroeconomic variables.
3) Explain the role of money, financial markets, and banks by using a simple model.
4) Grasp the differences between long-run and short-run macroeconomic equilibrium and discuss the effectiveness of fiscal and monetary policies in each time frame.

### Competencies that will be developed

 ✔ Specialist skills ✔ Intercultural skills Communication skills Critical thinking skills Practical and/or problem-solving skills

### Class flow

As stated in the "Course schedule," two times are used for one topic like household's behavior, firm's behavior, and so on.

### Out-of-Class Study Time (Preparation and Review)

To enhance effective learning, students are encouraged to spend approximately 100 minutes preparing for class and another 100 minutes reviewing class content afterwards (including assignments) for each class.
They should do so by referring to textbooks and other course material.
