The Demand Curve
 
02:45
Transcript: In the demand curve, we are trying to find out what’s the relationship between price and the quantity that is demanded. Let’s make it really simple by keeping everything else constant. That means ceteris paribus, given everything else constant. Let’s freeze them! Wow, only price and quantity left. With these 2 variables, we can draw 2 axes. The convention is to put the price on the vertical axis and quantity on the horizontal axis. Remember, as consumers, we want to stretch our dollar. At $2, eww, apples are expensive, we’ll only get 1 apple. (pause) But at $1, woah, apples are cheaper now, we’ll get 3 apples. Then we connect the dots. Tada, the demand curve! Note-- it’s downward sloping. When price increases, quantity demanded decreases. When price decreases, quantity increases. The arrows are always in opposite directions. This is the law of demand: there’s an inverse relationship between price and quantity demanded, ceteris paribus, given everything else constant. Why? First, it’s because of substitution effect. When apples get more expensive, we substitute apples with something else, like oranges. So we buy fewer apples. There’s also the income effect. Given the same income, when apples get more expensive, our purchasing power erodes. We feel our wallets shrinking. Remember the summary from the previous video? Why did I state quantity demanded here and demand here? What’s the difference? If you like this video, remember to like and subscribe. Next up: Change in quantity demanded vs change in demand _____________________________________________________ Why is the demand curve downward sloping? Because there's an inverse relationship between price and quantity demanded. Why is there an inverse relationship between price and quantity demanded? Why does price and quantity demanded change in opposite directions? Why price increases, why does quantity demanded decrease? Well, it's because of the substitution effect and income effect. When the price of apple increases, for example, we tend to substitute apples with some other similar goods like oranges. In addition, when price increases, our purchasing power drops. With the same amount of money, we can now buy fewer goods. So our real income decreases and we purchase fewer goods. This is called the income effect. The law of demand states that there is an inverse relationship between price and quantity demanded. The higher the price, the fewer the number of people willing and able to buy a good. Hence, the demand curve slopes downwards. The gradient of the curve is negative.

Change in Demand vs Change in Quantity Demanded- Key Concept
 
01:47
A change in demand is when the whole curve shifts and a change in quantity demanded is movement along the demand curve due to a change in price. Price Doesn't shift the curve.

Change in demand vs. change in quantity demanded
 
03:06
This movie explains the difference between a change in demand and a change in quantity demanded. The trick here is to remember that demand represents the relationship between price and quantity while quantity demanded is a single number that the consumers wish to purchase. Sometimes a question will ask what the change in quantity demanded is (which is a number) or what will happen to change demand (which requires a change in one of the determinants).

This is an update to the 2012 version of the lesson introducing how to determine an equation for demand using price and quantity data from a demand schedule or a demand curve. In parts 2 and 3 of this lesson we'll examine how changes in price and the non-price determinants of demand will lead to movements along a demand curve or a change in the 'a' and 'b' variables and a shift in demand.

How Substitutes and Complements Affect Demand
 
04:20
This video shows how changes in the price of a related good (a substitute or complement) can affect demand for a good. Decreases in the price of a substitute decrease demand for a good, while increases in the price of a substitute increase demand for a good. Conversely, decreases in the price of a complement increase demand for a good, while increases in the price of a complement decrease demand for a good.

Supply and Demand - Explained the EASY way - A caveman could even understand this..
 
08:12
Supply and Demand explained in an EASY way for all you people who struggle with this Message me if you have any questions! Sorry for the audio distortion my webcam is lame.. Supply and demand is perhaps one of the most fundamental concepts of economics and it is the backbone of a market economy. Demand refers to how much (quantity) of a product or service is desired by buyers. The quantity demanded is the amount of a product people are willing to buy at a certain price; the relationship between price and quantity demanded is known as the demand relationship. Supply represents how much the market can offer. The quantity supplied refers to the amount of a certain good producers are willing to supply when receiving a certain price. The correlation between price and how much of a good or service is supplied to the market is known as the supply relationship. Price, therefore, is a reflection of supply and demand.

Factors Affecting Demand.
 
03:40
Transcript: Let’s imagine we are all consumers. What makes us want to buy more apples or fewer apples? Prices. At $2, we’ll say, nah, it’s too expensive. Let’s just get 1. But if the price drops to $1, we’ll say, cool, let’s get 3 apples now. Tastes and preferences. Hey, I saw an advert today. Apples are good for health. All of a sudden, I want to buy more apples. When tastes shift towards apples, demand for apples increases. Price of complements. We say goods are complements of each other when they are normally bought together. For example, printer and ink cartridges. Or bread and jam. If bread gets cheaper, what happens to our demand for jam? Well, bread gets cheaper, we buy more bread, so we’ll buy more jam. Price of substitutes. Substitutes are goods that are bought for the same purpose. For instance, Pepsi and Coke are substitutes. When price of Pepsi drops, we’ll start to think, hey, let’s buy fewer cans of Coke and switch to Pepsi. They are the same thing anyway. So when price of Pepsi drops, demand for coke decreases. Income. You know, we all have this lust for material stuff? And we think that when we make more money, we are going to buy more of this and this and that? These type of goods are called normal goods. When our income increases, we want to get more normal goods like cars. There’s another category of goods called inferior goods. For example, food from roadside stalls. Perhaps your income increases and think, this food is inferior! You have more money, you want to eat in a restaurant now. When our income increases, we demand fewer inferior goods. Expectation of prices. “There’s a drought going on in Thailand. Shortage of rice in the near future is expected”. Crap, no rice? Man, I think price of rice is going to increase. Better go buy and stock up some rice now. So if we think future prices of rice will increase, our demand for rice today increases. Population. When the number of people on an island increases, the demand for houses increases. When population increases, demand for something will increase. So this is the summary. But hey, there are so many factors affecting demand. I’m getting confused. How do I graph the demand curve? If you like this video, remember to like and subscribe.

Supply and Demand
 
02:23
http://economicsdetective.com/ If you've only heard of one economics concept, it's probably supply and demand. Eventually we'll want to derive this concept from basic assumptions about utility and cost functions, but for now I'll just go through the 2-minute version. Let's start with supply. A supply curve is a relationship between the price of a certain good, and the amount of that good producers make. Let's say they're producing umbrellas. Supply curves typically slope upwards, since a higher price means producers can earn more from each item they sell, so it's worth it for them to produce more of that item. Now, on to demand. A demand curve is a relationship between the price of a certain good, and the amount of that good buyers want to buy. Although there are exceptions, most demand curves slope downwards. Intuitively, you'll buy more of something if it's cheaper. If we graph our supply curve and our demand curve together, we get this cool little X. The price at which supply and demand cross is the market-clearing price. If the price is at the market-clearing level, producers produce exactly as many umbrellas as as buyers want to buy, so every umbrella is sold, and everyone who wants to buy an umbrella can do so. What if the price of umbrellas is higher than the market-clearing price? Then producers make more umbrellas than buyers are willing to buy at that price, and we have a surplus. Similarly, if the price of umbrellas is set below the market-clearing price, buyers want to buy lots of umbrellas, but producers aren't so eager to produce that many, so there is a shortage of umbrellas. It's important to realize that the words "surplus" and "shortage" always refer to price-phenomena. 1000 umbrellas could constitute a surplus if the price of an umbrella is $100, or it could constitute a shortage if the price of an umbrella is $1. Where would we expect to see prices in our supply and demand model? The answer depends on many things. It depends on whether there is one producer or many, on whether there is one buyer or many, on what the laws are, and on how quickly the market can react to a sudden rain storm.

Change in demand versus change in quantity demanded
 
02:11
It is important to distinguish between a shift of the demand curve and a movement along the demand curve. A shift of the demand curve occurs whenever any of the nnon-price factors change. A new demand relation is formed and is referred ot as a change in demand. A movement along the dmeand curve takes place when the price of the good or service changes. This is referred to as change in quantity demanded.

What happens to equilibrium price if both supply and demand increase
 
02:59
This video shows the potential outcomes for equilibrium price, if both the supply and demand curves shift right. The answer is unknown without knowing the magnitudes of the shifts, and this is explained. We explain what happens to cause the changes in both supply and demand and then demonstrate the resulting effect that these changes have on the price. We can see from the video that there is definite direction that price must move but that is not the end of the story. We also have to take into account the magnitude of the changes to both supply and demand. Once we know the magnitude of the changes we can figure out the new equilibrium price and whether this equilibrium price will be higher or lower than the original market price. We can also then explore the equilibrium quantity to see how it compares to the original market quantity found in the beginning of the problem.

Relationship between Demand and Supply | मांग और आपूर्ति के बीच का संबंध
 
03:07
Hi dear friends, I just uploaded this video for the explanation about description of Supply and Demand Relationship. Relationship Between Demand and Supply. Supply and demand is perhaps one of the most fundamental concepts of economics and it is the backbone of a market economy. Demand refers to how much (quantity) of a product or service is desired by buyers. The quantity demanded is the amount of a product people are willing to buy at a certain price; the relationship between price and quantity demanded is known as the demand relationship. Supply represents how much the market can offer. The quantity supplied refers to the amount of a certain good producers are willing to supply when receiving a certain price. The correlation between price and how much goods or services are supplied to the market is known as the supply relationship. Price, therefore, is a reflection of supply and demand.

Supply Curve. Why is there a direct relationship between price and quantity supplied?
 
02:01
Transcript: 1 In the supply curve, we want to know the relationship between price and quantity supplied. Let’s make it really simple by keeping everything else constant. That means ceteris paribus, 2 Great, only price and quantity left. As usual, we put the price on the vertical axis and quantity on the horizontal axis. JINGLE As producers, we love profits like bees love honey. Since price increases revenue, (pause) Increase in revenue increases profits, The higher the price, the merrier! 3 At $2, we’ll supply 10 cakes. But at $4, woah, higher price, Let’s supply more cakes. (20) Connect the dots. Tada, the supply curve! Note-- it’s upward sloping. When price increases, quantity supplied increases. When price decreases, quantity supplied decreases. The arrows are in the same direction. This is the law of supply: there’s an direct relationship between price and quantity supplied, ceteris paribus, given everything else constant. If you like this video, remember to like and subscribe. Next up: Change in quantity supplied vs change in supply _____________________________________________________ Why is there a direct relationship between price and quantity supplied? How does the supply curve look like? In a supply curve, the price is on the vertical axis and the quantity is on the horizontal axis. Since revenue minus cost equals to profit, as price increases, revenue increases, so profit increases. For producers, the higher the price, the better. So they will supply more goods. Hence, as price increase, quantity supplied increases. There is a direct relationship between price and quantity supplied. So the supply curve slopes upwards. In other words, the supply curve has a positive gradient. The law of supply states that there is a direct relationship between price and quantity supplied.

The Total Revenue Test of Price Elasticity of Demand ( part 1)
 
08:17
By looking at how a change in price affects the total revenues of producers in a market (whether TR increases or decreases) we can draw some quick and accurate conclusions about whether demand for a good is elastic, inelastic or unit elastic between two prices. We'll also learn that even along a straight-line demand curve there is a RANGE of elasticities of demand for every good.

Laws of Demand and Supply | Demand and Supply Curves - Fundamental Economics
 
07:30
This is a very quick video about the Laws of Supply and demand as well as a brief introduction to demand and supply curves. If this video is a little fast, we apologize. Our lessons are meant to be fast. Read more below. What is the law of supply? The law of supply describes the direct relationship between price and quantity. This means that as price increase, quantity also increases. This tells us that the supply curve, a graphical representation of the law of supply, is upward sloping since the slope is positive. The law of demand on the other hand describes the indirect relationship between price and quantity demanded by consumers. This means that as price increases, consumers demand less. This is represented by the demand curve as a downward sloping line since it has a negative slope. If you find anything in this video, please let us know in the comment section and hopefully we can get it fixed or clarify the error in the description! Lastly, If you need any clarification on the subject matter in this video, please eave a comment. Hopefully either us or one of your fellow leaarners can answer your question!
