Final answer:
The statement about the theory of liquidity preference is false, as it does not conflict with the ideas of supply and demand. Buyers can pay more, and sellers can sell for less than the equilibrium price for various reasons. A price floor does not shift demand or supply but sets a minimum legal price.
Step-by-step explanation:
The statement "The theory of liquidity preference is largely at odds with the basic ideas of supply and demand" is false. The theory of liquidity preference, developed by John Maynard Keynes, relates to the demand for money, particularly the decision to hold cash versus securities. This theory suggests that the interest rate is the 'price' of money that equates the supply of and demand for money. The higher the interest rate, the less money held for speculative reasons; the lower the interest rate, the more money held.
Regarding goods market behavior, the statement, "In the goods market, no buyer would be willing to pay more than the equilibrium price," is false because there are various reasons why buyers may be willing to pay more. For example, in the case of perceived shortages, necessity, or the desire for luxury or unique items, buyers may place a higher value on the product than the current market price.
Similarly, the statement, "In the goods market, no seller would be willing to sell for less than the equilibrium price," is also false. Sellers may be willing to sell at lower prices for reasons such as the need for liquidation, market entry pricing strategies, or competition.
A price floor is a minimum legal price set by the government. It does not shift the demand or supply curve; rather, it sets a minimum price that can be charged for a good or service. So, the correct answer to the question of what a price floor will usually shift is d. neither.
