Steve went to his favorite hamburger restaurant with $3, expecting to buy a $2 hamburger and a $1 soda. when he arrived he discovered that hamburgers were on sale for $1, so steve bought two hamburgers and a soda. steve's response to the decrease in the price of hamburgers is best explained by: the substitution effect. the income effect. the price effect. a rightward shift in the demand curve for hamburgers.

the answer is "b.the increased supply will create a surplus. "

the essential thought behind price controls is straightforward - utilize the power of law to modify the equilibrium of a market. for instance, the legislature may choose that the steel business needs to survive, and in this way pass a law to set a value floor on steel. this implies all steel sold must offer at or over the floor value, which must be set over the equilibrium cost for it to have any impact. the switch could likewise happen - the administration can choose that steel is excessively costly and set a value roof underneath its equilibrium value, with the goal that all steel must be sold at or beneath that ceiling.
