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.This course is an introduction to the microeconomic theory of markets: why we have them, how they work, what they accomplish. We will start with the concept of scarcity and how specialization according to comparative advantage helps us achieve more than we could alone. Next we model a marked using the tools of Supply and Demand and learn what well working markets accomplish and what their limit are. We end by exploring the impact of government intervention on perfect markets. Examples are taken from everyday life, from goods and services that we all purchase and use. We will apply the theory to current events and policy debates through weekly exercises. These will empower you to be an educated, critical thinker who can understand, analyze and evaluate market outcomes.
