You and other college students are deciding whether to major in music or engineering. You learn that there is a shortage of engineers, making it easy for engineering graduates to find employment, while there is a glut of musicians for whom finding a job is difficult. As a result, you and many other college students decide to major in engineering. Which economic principle does this illustrate? Individuals do not normally take into account the decisions of other individuals. Changes in incentives are unlikely to change the decisions people make. Markets tend to move towards equilibrium as individuals respond to incentives. Government intervention can improve efficiency when there is a market failure. Specialization leads to economic efficiency.

What is the 3 step recipe for predicting market outcomes?
Step 1: Determine which curve is shifting (supply, demand, or both). Remember that any change affecting buyers or their marginal benefits will shift the demand curve, while any change affecting sellers or their marginal costs will shift the supply curve. Step 2: Determine if it's an increase, shifting the curve to the right, or a decrease, shifting the curve to the left. An increase in marginal benefit is an increase in demand, while an increase in marginal cost creates a decrease in supply. Step 3: Determine how prices and quantities will change in the new equilibrium. Compare the old equilibrium with the new equilibrium.
What are the three symptoms in a market that is in disequilibrium?
Symptom 1: Queuing. When you're driving around looking for a spot, you're effectively queuing—waiting in line—for the next available spot. The extra time you spend in the queue raises the effective price you're paying because it will cost you both time and money to get a spot. Symptom 2: Bundling of extras. When you bought dinner just so you could get the valet to park your car, you were effectively buying extras (that dinner) so you could get the thing you wanted (the parking spot), and this effectively raises the price you're paying to park. Symptom 3: A secondary market. By parking in someone else's driveway, you've found a way around the "official" market for parking spots.

During this same time, drivers start to prefer compact cars over trucks, leading to a decrease in the demand for trucks. Which of the statements most accurately describes what happens to the equilibrium price and quantity of trucks? The equilibrium price will increase and the equilibrium quantity will increase. The equilibrium price will decrease and it is unclear how the equilibrium quantity will change. The equilibrium quantity will decrease and it is unclear how the equilibrium price will change. The equilibrium price will decrease and the equilibrium quantity will decrease.
The equilibrium price will decrease and it is unclear how the equilibrium quantity will change.
What is the price-quantity principle?
The higher the price, the higher the quantity supplied.
What is the Law of large numbers?
The law of large numbers states that as a company grows, it becomes more difficult to sustain its previous growth rates.
how are markets organized?
There are many different ways in which buyers and sellers meet, and each of them counts as a market. A few examples are illustrated in Figure 1. In some cases, like in a coffee shop, prices are posted, and you simply pay the price, grab your latte, and go. Alternatively, perhaps you've participated in an auction, where the price you pay depends on how much the other bidders forced you to raise your bid
What is an equilibrium price?
There's only one price at which the quantity supplied equals the quantity demanded, this is the equilibrium price.
