We make economics decisions every day: what to buy, whether to work or play, what to study. We respond to markets all the time: prices influence our decisions, markets signal where to put effort, they direct firms to produce certain goods over others. Economics is all around us.

The Concept of Scarcity
Where do markets come from? We will start with understanding the constraint of scarcity that we face and the concept of opportunity cost that reflects the true cost of any decision we make. We will learn to model scarcity using the Production Possibilities Frontier that allows us to visualize tradeoffs, distinguish between efficient, inefficient and unattainable points. We will also discuss how economic growth affects our options and allows us to achieve the previously unattainable.

Specialization & Trade
Trade allows us to achieve the unattainable- we can consume more than we can produce on our own. We will introduce the concept of Comparative Advantage and discuss how gains from specialization allow us to use our resources efficiently. We will apply these concepts to a simple model of trade, showing that now the Consumption Possibilities Frontier allows points outside the Production Possibilities Frontier.

Supply and Demand
We will introduce the central model of Supply & Demand. This will allow you to communicate with other economists and finally understand those business pages and market updates. We will distinguish between a movement along and a movement of the supply & demand curves. We will define market equilibrium as understand that at an equilibrium price there is neither excess demand nor excess supply. We will end by a few scenarios where exogenous changes affect supply and/or demand and analyze the impact on equilibrium price and quantity.

Understanding Markets: Elasticities, Market Surplus, Efficiency, and Equity
There is a lot of terminology this week. We will introduce of the concept of elasticity of demand that measures the responsiveness of quantity demanded to a change in the price of a good. We will explore the relationship between change in price and revenue or sales and how elasticities can help us predict whether a decrease in price will increase or decrease revenue. We then introduce other elasticities of note: cross price elasticity, income elasticity and elasticity of supply. We end the week by exploring the great accomplishment of markets: maximizing the size of the pie or the total benefit to society.

Excellent course on the principles of markets and the effects of taxes and subsidies. Really enjoyed it and learned a lot. You definitely start to see the world around you in a different way.
由 WS 提供Mar 4, 2020
I really liked this course. The lecturer is able to convey terminologies clearly in a short time. The problems are more sophisticated and worth time thinking instead of just toy questions.
由 JR 提供Jun 6, 2020
The professor was clear and concise. I learned a lot without ever feeling overwhelmed. The quiz questions were relevant to the material covered and improved my understand of the material.
由 AP 提供May 16, 2020
The information I gained during this course will surely help me in becoming a better economist in the future and I found all the concepts quite easy as they were explained very well.
常见问题
我什么时候能够访问课程视频和作业？
Access to lectures and assignments depends on your type of enrollment. If you take a course in audit mode, you will be able to see most course materials for free. To access graded assignments and to earn a Certificate, you will need to purchase the Certificate experience, during or after your audit. If you don't see the audit option:
- The course may not offer an audit option. You can try a Free Trial instead, or apply for Financial Aid.
- The course may offer 'Full Course, No Certificate' instead. This option lets you see all course materials, submit required assessments, and get a final grade. This also means that you will not be able to purchase a Certificate experience.
我购买证书后会得到什么？
您购买证书后，将有权访问所有课程材料，包括评分作业。完成课程后，您的电子课程证书将添加到您的成就页中，您可以通过该页打印您的课程证书或将其添加到您的领英档案中。如果您只想阅读和查看课程内容，可以免费旁听课程。
