Microeconomics studies individual economic units — consumers, firms, and markets — and the decisions they make. It examines how prices are determined by supply and demand, how consumers maximise utility given budget constraints, and how firms choose output levels and pricing stra Read more
What is 'Supply'?
EasySupply is a fundamental economic concept that describes the total amount of a specific good or service that is available to consumers. The "Law of Supply" states that as the price of a good increases, producers will want to supply more of it to make more profit.
Supply isn't just about what is in the stores today; it also includes what is in warehouses and what factories are currently making!
What is a 'Giffen Good'?
HardA Giffen Good is a rare type of inferior product that defies standard economic theory: as the price of the good increases, people actually buy more of it. This usually happens with staple foods (like rice or bread) in very poor communities.
If the price of rice goes up, a poor family might not be able to afford meat anymore, so they have to buy even more rice just to survive!
What is the law of demand?
EasyThe Law of Demand states that, if all other factors remain equal, the higher the price of a good, the fewer people will demand that good. In other words, price and quantity demanded have an "inverse" relationship.
This law is visualized on a graph as a downward-sloping line, showing that as you move along the price axis from high to low, the quantity increases!
What is 'Inferior Good'?
MediumAn Inferior Good is an economic term for a product whose demand decreases as consumer income increases. These are typically lower-quality items that people only buy because they cannot afford something better, such as instant noodles or public bus rides. When a person's income goes up, they stop buying the inferior good and switch to a more expensive alternative.
During a recession, sales of "inferior goods" like canned meat and thrift store clothes actually tend to go up!
What are 'Giffen Goods'?
HardGiffen Goods are a rare type of inferior good for which demand increases as the price increases, defying the standard Law of Demand. This usually happens with basic staples (like bread or rice) for very poor people; when the price goes up, they can no longer afford "luxury" items like meat, so they end up buying even more of the basic staple to survive.
The most famous theoretical example is the Irish Potato Famine, where people allegedly bought more potatoes as prices rose because they had no other food options!
What is the term for the price at which quantity demanded equals quantity supplied?
EasyThe Equilibrium Price is the market price where the quantity of goods supplied is exactly equal to the quantity of goods demanded. At this point, there is neither a surplus nor a shortage, and the market is "cleared."
In a truly free market, the "Invisible Hand" is always pushing prices toward equilibrium; if the price is too high, a surplus will form and force the price down!
Demand means?
EasyIn economics, demand refers to the consumer's desire and willingness to purchase a specific good or service at a particular price, supported by the ability to pay for it. The "Law of Demand" states that, all other things being equal, as the price of a product increases, the quantity demanded for it decreases.
There is a rare type of product called a "Veblen Good" (like designer handbags or luxury cars) for which demand actually increases as the price goes up because people perceive the higher price as a symbol of status and exclusivity.
What is 'Demand'?
EasyDemand is the consumer's desire and willingness to pay a price for a specific good or service. The Law of Demand states that as the price of an item goes up, consumers will generally want to buy less of it.
"Pent-up demand" happens after a crisis when people suddenly rush out to buy things they couldn't get for a long time!
What measures price rise?
EasyThe Consumer Price Index (CPI) is the most widely used measure for tracking price rises (inflation) at the consumer level. It is calculated by taking a "basket" of commonly purchased goods and services-like bread, rent, and fuel-and tracking how the average price of that basket changes over time.
To keep the CPI accurate, the "basket" is updated every year to reflect modern trends; for example, in recent years, items like "VCRs" and "compact discs" have been removed and replaced with "streaming service subscriptions" and "smartwatches."
What is a 'Monopoly'?
EasyA Monopoly occurs when a single company or entity is the sole provider of a particular good or service, giving them the power to set prices without competition. This often leads to higher prices and less innovation for consumers.
A "Natural Monopoly" occurs when it is more efficient for one company to provide a service, such as water or electricity lines, because the cost of building duplicate infrastructure is too high!
What is 'Elasticity of Demand'?
MediumElasticity of Demand (specifically Price Elasticity) measures how sensitive the quantity demanded of a good is to a change in its price. If a small change in price leads to a large change in demand, the good is "elastic" (like luxury cars). If demand barely changes, it is "inelastic" (like life-saving medicine).
Companies use elasticity to decide whether to have a sale; if a good is inelastic, lowering the price won't increase sales enough to make more money!
What is microeconomics?
EasyMicroeconomics is the branch of economics that focuses on the behavior of individual people and small businesses. It studies how these individuals make decisions about what to buy, how much to work, and how companies set prices for their products based on the interaction of supply and demand.
Microeconomics often uses "Game Theory" to explain how businesses compete; for instance, it explains why two gas stations located across the street from each other often end up having identical prices despite being competitors.
Which type of good has demand increase as income increases?
MediumA normal good is a type of good for which demand increases as a consumer's income increases (and decreases when income falls). Most items, from organic food to new cars, are normal goods.
The opposite is an "inferior good" (like instant noodles or used clothing), where people actually buy less of it as they get richer and can afford better alternatives!
What is 'Price Ceiling'?
MediumA price ceiling is a government-imposed limit on how high a price can be charged for a product. A common example is "Rent Control" in large cities.
While price ceilings are meant to help poor people, they often cause "shortages" because if the price is too low, producers won't want to make/provide enough of the product!
What is 'Normal Good'?
MediumA Normal Good is a product whose demand increases as consumer income rises. Most things we buy, such as new clothes, restaurant meals, and electronic gadgets, fall into this category. When people have more money, they tend to "trade up" to better or more frequent versions of these goods.
Air travel is a classic normal good; as a country gets richer, its citizens start flying significantly more often for vacation!
Which curve shows demand?
MediumA demand curve is a graphical representation of the relationship between the price of a good or service and the quantity of it that consumers are willing to buy. In a standard graph, the curve slopes downward from left to right, showing that as the price decreases, people typically buy more of the product.
There are exceptionally rare items called "Giffen Goods" (usually basic staples like bread or rice in very poor regions) where the demand curve actually slopes upward-as the price of the staple food rises, poor people can no longer afford better food (like meat), so they are forced to buy even more of the basic staple!
What is elasticity?
MediumElasticity is a measure used in economics to show how sensitive the quantity demanded of a good is to a change in its price. If a small change in price leads to a huge change in demand, the product is "elastic" (like luxury vacations); if a big change in price barely changes the demand, the product is "inelastic" (like life-saving medicine).
One of the most inelastic products in the world is salt; because people only need a small amount and there is no substitute for it, they will usually keep buying the exact same amount even if the price doubles or triples.
What is oligopoly?
HardAn Oligopoly is a market structure in which a small number of large firms dominate the industry and have the majority of the market share. Because there are only a few players, each firm is acutely aware of the actions of its competitors; a price change or marketing campaign by one firm usually triggers a quick response from the others.
The commercial aircraft manufacturing industry is a classic "duopoly" (a type of oligopoly) dominated by just two giants: Boeing and Airbus. Because it is so expensive to build planes, it is nearly impossible for new competitors to enter the market.
What is 'Consumer'?
EasyA Consumer is a person or a group who intends to order, or uses purchased goods, products, or services primarily for personal, social, family, or household needs. In a market economy, consumers drive production because businesses only make what they think people will buy. The "Consumer Price Index" tracks how much these people have to pay for their daily needs.
In the US, consumer spending accounts for about 70% of the entire economy's activity!
What is 'Producer'?
EasyA Producer is a person, company, or country that makes, grows, or supplies goods or commodities for sale. Producers use the "factors of production"-land, labor, and capital-to create items that satisfy consumer wants. The goal of a producer in a capitalist system is typically to maximize profit.
With the rise of the internet, many people are now "Prosumers," meaning they both produce and consume content (like on YouTube or TikTok)!
