Hey, guys. Let's go ahead and define some key terms that'll help us understand and answer the question, what is economics? So our first term here, scarcity, it's the idea that in this world we have unlimited wants, but only limited resources to fulfill those wants. Right? So, for example, you know, my wants, I want a new guitar. I love to travel. Shoot. I'd even love to go to the moon. But it's gonna be kinda tough. Right? What kind of resources do I have? I definitely don't have a spaceship, so that's not gonna be happening anytime soon. I've got my time. So if I were to travel, yeah, I'd have the time for it, but what about the money? I don't have the money right now. I've got well, I've got my empty bank account. At least I have that. Maybe I can put some money in it eventually. So that's the idea. Right? We're gonna have to pick our battles here. We've only got limited resources and we've got all sorts of things that we're gonna want in this world. It kinda leads us to our next topic, trade-offs. It's the idea that we have to give up one thing to get something else. So for example, tonight, I've been planning to go to the Panthers game with my dad for a while here. Panthers, the Florida Panthers, that's our hockey team down here. And just last night, my friend calls me that there's a big party happening tonight, and all my friends are gonna be there. Well, I'm gonna have to pick 1 or the other here, right, and I'm spoiler alert I'm not gonna sell out my dad so I'll go to the Panthers game tonight. But it's not always 2 things that we're choosing between. What if it's your day off and you just wanna go to the beach? Right? Maybe you got the day off. Let's go to the beach. What are you giving up to go to the beach? Well, the opportunity to just stay home. Right? You could have just stayed home instead. Just relax at home. So, you know, there's always something you're giving up, and that's the idea of an opportunity cost, The value of the next best alternative to a choice. Right? So a good example is something you'll probably relate to, going to college. Right? When you go to college, you're giving up the opportunity to get a full-time job right away. Right? Maybe some of you have part-time jobs. I'm sure a lot of you are full-time students too though. The idea here is that when you go to college, yes, you have all the costs of college tuition, fees, room and board, books, right? But there's also that opportunity cost of having gotten a job right away. So you're giving up all that money you could have already been making. So with these concepts, let's define economics.
Introduction to Economics: Study with Video Lessons, Practice Problems & Examples
Created using AIEconomics is the social science that studies how individuals and societies make decisions under conditions of scarcity, where unlimited wants meet limited resources. Key concepts include scarcity, trade-offs, and opportunity cost, which highlight the necessity of making choices. Microeconomics focuses on individual and business decisions, while macroeconomics examines the economy as a whole, addressing issues like inflation, unemployment, and economic cycles. Understanding these distinctions is crucial for analyzing economic behavior and policy implications.

Definition of Economics:Micro vs. Macro

Alright. So let's quickly discuss the difference here between microeconomics and what we're studying here, macroeconomics. Economics, in general, is defined as a social science focused on the decisions made by individuals, institutions, and society under conditions of scarcity. The key idea here is scarcity, where we have scarce resources and how we are going to use these resources. The decisions that we make on an individual level and on larger levels as well.
In microeconomics, a course might teach you about the choices that individuals and businesses make, such as how prices affect a market for a certain product, the supply and demand of a product, how a business maximizes its profit, and how many laborers to hire. These are all micro ideas on a small scale, concerning what one business or one person might do in one market.
However, here in this course, we're talking about macroeconomics, which deals with the 'big picture'. We're discussing bigger issues, studying the economy as a whole, focusing on nations, not just national but global economics. We're going to deal with bigger ideas like recessions and what causes recessions, the causes of economic booms, and inflation. We'll explore how inflation affects interest rates and the supply of money, along with issues like unemployment. We aim to understand the reasons why unemployment happens, the types of unemployment that exist, and the effects they have on the economy.
Here in this course, we're focusing on macroeconomics, but you might also encounter questions that ask whether a specific issue deals with microeconomics or macroeconomics. It's good to understand the difference between the two.
Alright, let's go ahead and move on to the next topic.

What is the definition of scarcity in economics?
Scarcity in economics refers to the fundamental problem that arises because resources are limited while human wants are unlimited. This means that there are not enough resources to fulfill all our desires and needs. For example, you might want to buy a new car, travel the world, and save for retirement, but you only have a limited amount of money and time. Scarcity forces individuals and societies to make choices about how to allocate their limited resources to satisfy their most important needs and wants. This concept is central to the study of economics as it drives the need for trade-offs and opportunity costs.
Created using AIWhat is the difference between microeconomics and macroeconomics?
Microeconomics and macroeconomics are two branches of economics that focus on different levels of analysis. Microeconomics examines the decisions made by individuals and businesses, such as how prices affect the supply and demand of a product, how a business maximizes its profit, and how many workers to hire. It deals with specific markets and the behavior of individual economic agents. On the other hand, macroeconomics looks at the economy as a whole, addressing larger-scale issues like inflation, unemployment, economic growth, and recessions. It studies national and global economic trends and policies. Understanding both is crucial for a comprehensive analysis of economic behavior and policy implications.
Created using AIWhat is opportunity cost and why is it important in economics?
Opportunity cost is the value of the next best alternative that is forgone when a choice is made. It represents the benefits you could have received by taking a different decision. For example, if you decide to spend time studying for an exam instead of going out with friends, the opportunity cost is the enjoyment and social interaction you miss out on. In economics, opportunity cost is important because it helps individuals and societies make informed decisions by considering the potential benefits of alternative options. It highlights the trade-offs involved in every decision, ensuring that resources are used efficiently.
Created using AIHow does inflation affect the economy?
Inflation is the rate at which the general level of prices for goods and services rises, eroding purchasing power. When inflation is high, each unit of currency buys fewer goods and services, which can reduce consumer and business spending. This can lead to slower economic growth. Inflation also affects interest rates; central banks may raise rates to control inflation, making borrowing more expensive. Additionally, inflation can impact savings, as the real value of money saved decreases over time. However, moderate inflation is often seen as a sign of a growing economy, encouraging spending and investment.
Created using AIWhat causes economic recessions?
Economic recessions are periods of significant decline in economic activity, typically defined by two consecutive quarters of negative GDP growth. Several factors can cause recessions, including high inflation, which reduces purchasing power; high interest rates, which make borrowing expensive; reduced consumer and business confidence, leading to decreased spending and investment; and external shocks, such as natural disasters or geopolitical events. Additionally, financial crises, such as the collapse of major financial institutions, can trigger recessions. Understanding these causes helps policymakers implement measures to mitigate the impact and support economic recovery.
