Key Concepts

Graphical Representation

In a supply and demand graph, the initial demand curve represents the original relationship between price and quantity demanded. When consumers expect future prices to rise, the entire demand curve shifts to the right, indicating a higher quantity demanded at each price level. This graphical shift highlights how expectations can affect market behavior independent of an immediate change in the good's price.

Consumer Expectations

Consumer expectations refer to the beliefs that buyers have about future market conditions, such as anticipated price changes. When consumers expect prices to increase in the future, they are more likely to purchase the good now, resulting in an increase in current demand that shifts the demand curve to the right.

Demand Curve

The demand curve is a graphical representation that shows the relationship between the price of a good and the quantity consumers are willing to purchase, holding all else constant. It typically slopes downward, reflecting the inverse relationship between price and quantity demanded.

Movement Along vs. Shift of the Demand Curve

A change in the price of the good leads to a movement along the demand curve, meaning that the quantity demanded changes due to the change in price. However, a shift of the demand curve occurs when a non-price factor changes, such as consumer income, tastes, or expectations, altering the overall demand at every price level.

00:01 Once again, i welcome to a new problem.

00:04 This time we're still dealing with demand graphs.

00:08 And if you think about it, the x axis usually has the quantity demanded.

00:15 And the y axis usually has the prize.

00:18 And the demand graph is downward sloping.

00:21 And the reason for that is the fact that as prizes go up, meaning you're going upwards, like this, the demand goes down.

00:41 And that's along the graph.

00:42 So if you only look at price and nothing else, this is what's going to happen.

00:47 So everything else is constant.

00:50 All outside factors are constant.

00:52 But if you're thinking about the price versus the demand, that's what happens.

00:56 So we have a problem.

00:58 And in this particular problem, we, um, we, um, we, you know, assume that consumers anticipate a future increase in prices.

01:26 So consumers are anticipating a future increase in prices, and that's general increase in prices.

01:34 And because this is an outside event, it's a future increase in prices, it's an outside event.

01:40 We want to see how will this anticipation affect future or rather not future, but how will this anticipation? affect changes in demand.

02:13 So our understanding in this problem is the fact that you have demand, which is the represented by the overall graph.

02:34 And then you also have something called quantity demanded.

02:42 Which is represented by movement along the graph.

02:57 Demand by itself can shift due to outside factors.

03:07 So there are many other factors that can affect demand and cause it to shift.

03:12 So demand shows the relationship between price and quantity demanded.

03:17 At different prices.

03:19 So just by looking at this demand, for example, we're going to have a specific price here, p1, producing certain quantity demanded right there.

03:30 And then we could also have another prize at p2, producing another quantity demanded at d2.

03:37 What you notice is that you're staying on the same graph.

03:42 You're staying on the same graph, so you don't go outside the graph.

03:47 But you stay inside the graph.

03:51 If consumers anticipate a future rise in prices of a product, they will shift their behavior to stock, what we call purchase the product today before the prizes or prizes rise in the future before the prizes rise in the future...
