Which is the most accurate statement about trade?

Trade can make every nation better off.

A decrease in supply will cause an increase in price, which will cause a decrease in quantity demanded.

True

A price ceiling set above the equilibrium price is not binding.

True

An increase in price increases consumer surplus.

True

Economists often find it worthwhile to make assumptions that do not necessarily describe the real world.

True

If a major union goes on strike, then the country would be operating inside its production possibilities frontier.

True

If a supply curve is horizontal, then supply is said to be perfectly elastic, and the price elasticity of supply approaches infinity.

True

In principle, trade can make a nation better off, because the gains to the winners exceed the losses to the losers.

True

Necessities tend to have inelastic demands, whereas luxuries tend to have elastic demands.

True

Patent protection is one way to deal with technology spillovers.

buyers' responsiveness to a change in the price of a good.

inefficient, and the equilibrium does not maximize the total benefit to society as a whole.

Absolute advantage is found by comparing different producers'

input requirements per unit of output.

The business cycle is the

irregular fluctuations in economic activity.
