Key Concepts

Cross-Market Effects and Substitution

This concept refers to how changes in one market can spill over into related markets. For example, external events that affect the price of a key commodity can influence the prices of substitute or complementary goods. The effect is explained through the idea of cross-price elasticity, where an increase in the price of one product might lead consumers to shift their demand towards a substitute, affecting its market equilibrium.

Demand Shocks

A demand shock occurs when an external factor causes the demand for a product to suddenly change, shifting the demand curve to the left (a decrease) or to the right (an increase). These shifts could be due to changes in consumer preferences, income variations, seasonal trends, or other environmental influences, which in turn alter the equilibrium price and quantity in the market.

Supply and Demand Model

This is the basic framework in economics that shows how the interaction between buyers and sellers determines the market price and quantity. A supply-and-demand diagram illustrates the equilibrium where the supply curve intersects the demand curve, and any external changes will shift one or both curves, leading to new equilibrium outcomes.

Supply Shocks

A supply shock is an event that causes a sudden change in the supply of a good, typically shifting the supply curve either to the left (a decrease) or to the right (an increase). Such shocks can be caused by natural events, geopolitical tensions, or other external factors that affect production or availability, leading to changes in market prices and quantities.

00:01 Here we're going to be taking a look at the market forces of supply and demand and working to better understand how particular situations and occurrences in the market for different products, goods, and services are affected by such occurrences.

00:15 So let's start with our first one here.

00:17 You can see that i've given us a couple scenarios and a couple supply and demand curves to work with as well.

00:21 So what we're seeing here in our first one is that there's a cold snap that exists in florida.

00:27 So as a result, orange juice prices go up all over the country.

00:33 Now, what exactly happened on the supply and demand curve if we wanted to depict it? well, this cold snap in florida, we know that florida is big on growing oranges.

00:42 They're a big supplier of it.

00:44 So this cold snap occurs.

00:46 The orange crop dies, thus reducing supply.

00:50 So our supply curve is going to shift upward like this, right? this is our new supply because we have less of it now.

00:59 So as a result, you can see what our new equilibrium is.

01:02 All of a sudden, our quantity demanded has fallen, and our price has gone up.

01:10 All right, let's move on to our next one.

01:13 In new england, we see that when they warm up, when summer comes around, the caribbean hotel room prices drop dramatically.

01:21 Well, let's go ahead and depict this as well.

01:23 So new england warms up.

01:25 This means fewer people are likely traveling to the caribbean, right? they don't need to travel to warmer weather when it's already here for us.

01:33 So this means that demand is reduced for these caribbean hotel rooms.

01:38 So demand has fallen...
