g If the U. S. real exchange rate appreciates, U. S. exports a. increase and U. S. imports decrease. b. decrease and U. S. imports increase. c. and U. S. imports both increase. d. and U. S. imports both decrease.

The answer is B.

Explanation:

If dollar appreciates, imports become cheaper(decrease), meaning dollar will buy more of another foreign currency

because Americans will find foreign goods less expensive because they have to spend less for those goods and services in dollar.

In the same vein, exports rise(increase) or less profitable, causing the domestic demand to fall because foreigners will find American goods more expensive because they have to spend more for those goods and services in dollar

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.
