Principles of Supply and Market Dynamics Quiz

#1

Which of the following is NOT a determinant of supply?

Consumer preferences
Explanation

Factors such as input prices, technology, and expectations influence supply, not consumer preferences.

#2

What is the law of supply?

As price increases, quantity supplied increases
Explanation

Producers supply more at higher prices, assuming other factors remain constant.

#3

Which of the following is a determinant of market supply?

Taxes and subsidies
Explanation

Government policies like taxes and subsidies directly impact the supply of goods and services.

#4

Which of the following is a determinant of market demand?

Price of related goods
Explanation

Changes in the price of substitutes or complements influence the demand for a good.

#5

In economics, what does 'ceteris paribus' mean?

All else being equal
Explanation

It's a Latin term indicating the isolation of a single variable's effect while holding other variables constant.

#6

What is the law of demand?

As price decreases, quantity demanded increases
Explanation

Consumers buy more of a good as its price falls, ceteris paribus.

#7

What happens to equilibrium price and quantity if both demand and supply increase?

Price increases, quantity is indeterminate
Explanation

While price increases due to increased demand and supply, the change in quantity depends on the relative magnitude of the shifts.

#8

What is a price floor?

A legally established minimum price for a good or service
Explanation

Governments set price floors to prevent prices from falling below a certain level.

#9

What is the price elasticity of supply?

A measure of how much quantity supplied responds to a change in price
Explanation

It indicates the sensitivity of quantity supplied to price changes.

#10

What is the primary function of a market?

To facilitate exchange between buyers and sellers
Explanation

Markets bring together buyers and sellers to conduct transactions efficiently.

#11

Which of the following scenarios would cause a rightward shift in the supply curve?

A decrease in production costs
Explanation

Lower production costs enable firms to supply more at each price level, leading to a rightward shift in the supply curve.

#12

What does the law of diminishing marginal returns state?

As more units of a variable input are added to fixed inputs, marginal product eventually decreases
Explanation

Beyond a certain point, increasing the variable input while holding other inputs constant yields diminishing additional output.

#13

What is the difference between a change in supply and a change in quantity supplied?

A change in supply is caused by a change in non-price determinants, while a change in quantity supplied is caused by a change in price
Explanation

Shifts in supply curve result from factors like technology, costs, etc., whereas changes in quantity supplied occur due to price fluctuations along the supply curve.

#14

What is a perfectly elastic supply?

A situation where quantity supplied is infinitely responsive to price changes
Explanation

Even a slight change in price results in an infinite change in quantity supplied.

#15

What is the relationship between price and quantity supplied in a market with a perfectly elastic supply curve?

Price is constant regardless of quantity supplied
Explanation

Suppliers can sell any quantity at a fixed price, so quantity supplied doesn't affect price.

#16

What is a perfectly inelastic supply?

A situation where quantity supplied does not change in response to price changes
Explanation

Quantity supplied remains constant regardless of changes in price.

#17

What is the difference between a change in demand and a change in quantity demanded?

A change in demand is caused by a change in non-price determinants, while a change in quantity demanded is caused by a change in price
Explanation

Changes in demand result from factors like income, preferences, etc., whereas changes in quantity demanded occur due to price fluctuations along the demand curve.
