What is economics and what do economists do?
TLDRThis video script serves as an engaging introduction to the field of economics, presented by Dr. Pete Schuhmann. He defines economics as the study of how people, businesses, societies, and nations deal with scarcity and distribute scarce resources. He explains the two broad branches of economics: macroeconomics, which focuses on the entire economy, and microeconomics, which examines individual and firm-level decision-making. Dr. Schuhmann highlights key concepts like opportunity cost, trade-offs, and thinking at the margin, emphasizing the diverse array of topics economists study and the skills they employ, including critical thinking, math, statistics, and data analysis. He also discusses the diverse career paths available for those studying economics and the areas of agreement and debate within the field.
Takeaways
- 😃 Economics is the study of how people, businesses, societies, or nations deal with scarcity and distribute scarce resources.
- 🤔 Economists use various tools like math, statistics, data analysis, and reasoning to study economic phenomena and provide useful information to decision-makers.
- 🌐 Macroeconomics focuses on the study of the entire economy at the national and international level, while microeconomics examines individual and firm-level decision-making and dynamics.
- 💰 Economists analyze concepts like opportunity cost, trade-offs, incentives, and cost-benefit analysis to understand economic behavior and decision-making.
- 🔬 While economics aims to be objective and follows a scientific method, it is an inexact science due to the complexity and unpredictability of economic systems.
- 🏛️ Economists work in various sectors, including government, private firms, banking, consulting, academia, and non-governmental organizations.
- 🙅♂️ Not everyone who studies economics is an economist, as graduate training is often required to practice economics professionally.
- 🧑🤝🧑 While economists may disagree on specific issues, they generally agree on principles like voluntary transactions, analyzing costs and benefits, and designing public policies to improve social well-being.
- 🥇 Two of the most important concepts in economics are opportunity cost (the idea that every action involves trade-offs due to scarce resources) and thinking at the margin (analyzing incremental changes rather than absolute values).
- 🌳 The field of economics is broad and diverse, covering various topics and sub-disciplines, from agriculture and natural resources to labor and industrial organization.
Q & A
What is the definition of economics according to the script?
-Economics is defined as the study of how people, businesses, societies, or nations deal with scarcity.
What are the two broad branches of economics mentioned?
-The two broad branches of economics mentioned are macroeconomics and microeconomics.
Who is considered the father of the supply and demand model?
-Alfred Marshall is considered the father of the supply and demand model.
What concept did Adam Smith focus on in his economic theories?
-Adam Smith focused on the concept of rational self-interest and its ability to promote social well-being under certain conditions.
What is Milton Friedman known for in the 20th century?
-Milton Friedman is known as perhaps the 20th century's most vocal advocate for free markets.
What does the 'circular flow' model represent in economics?
-The 'circular flow' model represents the exchange between households and businesses, where households provide labor in exchange for income, and businesses provide goods and services in exchange for money.
How do economists study their discipline according to the script?
-Economists study their discipline using mathematics, statistics, data, and reasoning.
Is economics considered a science, and why or why not?
-The script suggests that economics can be considered both a science and not a science because, while it follows the scientific method of observation, theorization, and empirical testing, it lacks controlled experiments due to the complexity and uniqueness of economies.
What is the importance of opportunity cost in economics?
-Opportunity cost is crucial in economics as it represents the idea that every action involves giving up something else, highlighting the trade-offs due to scarce resources.
Do all economists agree on the same theories and policies?
-No, economists do not agree on everything. There is a lot of uncertainty and ambiguity in the field, leading to different viewpoints on theories and policies.

🎓 Introduction to Economics: Fundamentals and Applications
Dr. Pete Schuhmann presents an overview of economics, defining it as the study of how people deal with scarcity and distribute scarce resources. He distinguishes between macroeconomics, which focuses on the entire economy, and microeconomics, which examines individual and firm-level decision-making. Key concepts like opportunity cost and thinking at the margin are introduced as tools economists use to understand trade-offs and decisions. The discipline's scope is illustrated through various fields and applications, highlighting its relevance across diverse domains.
🔍 The Nature of Economic Inquiry: Methods and Approaches
This section delves into the methodological approaches employed by economists in their study of economic phenomena. It discusses the use of mathematical models, statistical analysis, data collection, and empirical testing to formulate theories and draw inferences. The section acknowledges the challenges posed by the absence of controlled experiments in economics, likening it to predicting the fall of leaves on a windy day rather than objects in a vacuum. The breadth of topics economists study is showcased through the Journal of Economic Literature Classification of Fields, spanning from agriculture and natural resources to international economics.
🧠 Key Concepts and Career Prospects in Economics
The section emphasizes two critical concepts in economics: opportunity cost and thinking at the margin. Opportunity cost highlights the notion of trade-offs and the idea that every action involves giving up something due to resource scarcity. Thinking at the margin encourages incremental analysis rather than absolute changes. The section also discusses career prospects for economics graduates, acknowledging the diverse opportunities available due to the versatile skillset acquired, including critical thinking, data analysis, and communication. It also addresses the uncertainty and disagreements within the discipline, while noting areas of consensus, such as the importance of incentives, voluntary transactions, and cost-benefit analysis in policymaking.
