Study Notes
Opportunity Cost
- Opportunity cost is the value of the next-best alternative that is given up when choosing one option over another
- It takes into account the costs and benefits of all other options and converts them into costs of the decision being made
- Implicit costs, which are not normally measured, should be included in opportunity costs
- Sunk costs, which are already spent and cannot be changed, should not be included in opportunity costs
History of Economics
- In the past, people believed that poverty was a result of God's will
- Enlightenment scholars looked for alternative explanations, such as the nature of land ownership
- Over time, the amount of knowledge expanded, and social sciences were divided into categories
- In the late 1800s and early 1900s, social science was further divided into economics, political science, and sociology
Economics in Perspective
- This book presents economics as a way of thinking, focusing on graphical supply and demand frameworks
- It goes beyond traditional Marshallian economics, introducing a wider variety of models and thinking
- Marshallian economics is primarily about policy, not theory, and sees institutions, political and social dimensions of reality as important
Types of Experiments
- Laboratory experiments: individuals are brought into a computer laboratory and their reactions to various treatments are measured and analyzed
- Field experiments: experiments in which treatments in the real world are measured and analyzed
- Computer experiments: simulated economies are created within the computer and results of various policies are explored
- Natural experiments: naturally occurring events that approximate a controlled experiment, such as the effect of raising the minimum wage in New Jersey
Real-World Application: Economists and Market Solutions
- Economic reasoning is increasingly used in government policy
- The regulation of pollution is an example of how economic reasoning can be applied to policy
- The Clean Air Act of 1970 capped the amount of pollutants that firms could emit, but a market-based approach could have achieved the same goal at a lower cost
- Economists argue that changing the incentives that individuals face can lead to better policy outcomes
Learn about the concept of opportunity cost in economics, where choosing one option means giving up others, and how it applies to everyday life.
