According to Marshall, which products had "very elastic" demand among working-class consumers? Which products had inelastic demand among the same group?

Suppose the supply function for a certain item is given by $S(q)=(q+1)^{2}$, and the demand function is given by $D(q)=\frac{1000}{q+1}$. a. Graph the supply and demand curves. b. Find the point at which supply and demand are in equilibrium. c. Find the consumers’ surplus. d. Find the producers’ surplus.

According to the World Bank, at the end of 2013 (t = 0) the U.S. population was 316 million and was increasing according to the following model: $P(t)=316 e^{0.0074 t}$, where P is measured in millions of people and t is measured in years after 2013. a. Based on this model, what will be the population of the United States in 2020? b. Determine when the U.S. population will be twice what it is in 2013.

Explain why you think, or do not think, that several things could shift the demand curve at the same time.

The last paragraph in this section uses the phrase "we have to use our judgment." What does the author mean by this phrase?

How are the three cases of demand elasticity measured?

How do we measure the three cases of demand elasticity ?

A baker knows that her customers will pay 5 dollars for a loaf of bread, but the marginal utility they get decreases after the first loaf. How might the baker get her customers to buy more than one loaf?

Explain how quantity and price appear on a graph in economics, and use that information to explain why a demand curve is downward sloping.

What impact does an anti-price gouging law have on an economic system ?

Does a change in consumers' tastes lead to a movement along the demand curve or a shift in the demand curve? Does a change in price lead to a movement along the demand curve or a shift in the demand curve?
