Introduction to Economics

Session B: July 20 - July 30, 2021
9:30 a.m. - 12 p.m.
Dick Oosthuizen

Introduction to Economics will survey introductory concepts in economics, emphasizing key topics in microeconomics and macroeconomics. This will allow students to use economic arguments as often used in debates about government policies, discussion of business strategies, and many other arenas in life. The goal of the course is to teach students to “think like an economist,” which I hope will help them to understand the world around you, make better economic decisions in life, and be a more informed citizen and voter. To achieve this goal, the course will combine lectures and recitations. Lectures are used to introduce concepts generally, convey the big picture, and talk about economics, the world, the news and current events. Recitations are used to review concepts and solve examples, and to discuss economic policy questions.

Economics is the study of how society allocates its scarce resources. Microeconomics is the study of the behavior of households and firms, whose collective decisions determine how resources are allocated in a free market economy. We will study when markets are likely to produce “efficient” outcomes, and when government intervention may improve or harm the competitive market outcome. We will use economic theory to analyze issues like a gas tax to change reliance on oil, minimum wages to increase salaries of the working class, and government subsidies to increase education. Macroeconomics is the study of the economy as a whole. We will understand how the size of the US economy is determined, how unemployment is measured, and how inflation affects everyday life, among other areas. We will study policy options that the government and the Federal Reserve Bank consider, and discuss the pros and cons of their actions.

Goals for students

  • To gain a broad understanding of economics in general.
  • To get a grasp on how to use economic arguments as seen in daily newspaper articles, as well as more advanced text excerpts.
  • To distinguish key fields in economics, and to know the basic arguments used in each of them, such as microeconomics, macroeconomics and (a slight exposure to) finance.
  • To expose them to areas of research, possible careers, and learning opportunities within the field of economics, such as a possible Bachelor’s and Master’s degree after high school.

Possible assignments

Homework Exercises
Students will be expected to prepare a few questions before each meeting to stimulate discussions during recitations regarding the relevant content. Students will work in groups of 2-4 on these problems. These problems are based on the material in the lectures and relevant accessible discussion articles, to be handed out after the recitations after students are first exposed to the relevant material. They will be expected to have solved the problems the next day so we can discuss solutions.

Group research projects

If possible, students are invited to write discussions about relevant economic policy decisions. Why did the Federal Reserve make the decision to increase the money supply? According to recent literature, was the timing correct? How did Europe do? Or: What caused the Great Recession, and are we on the brink of another crisis? Why or why not? What are the risk factors involved? The idea for them is NOT to dive deep into the literature and construct advanced proofs regarding each statement. Instead, they are asked to review a select amount of discussion articles which will be very accessible to them. Based on these articles, they are invited to write a short summary of their findings, and what areas they think should be explored in the future. On day 9, students will present their topics and research.


In addition to readings, students are encouraged to read on the internet, such as Bloomberg, The Economist, Wall Street Journal, or a financial newspaper for 20-30 minutes a day. The goal of this exercise is for them to be exposed to different aspects of Economics and Finance, and be up to date about the current developments.
