Marking brainliest / written answers 1. under what conditions is a market at equilibrium? 2. when supply exceeds demand, what happens to prices? 3. what kinds of goods require search costs? 4. how does a supply shock affect equilibrium pricing? 5. why do buyers and sellers conduct business on the black market?

1) When the supply and demand curves intersect, the market is in equilibrium. This is where the quantity demanded and quantity supplied are equal.

2)The corresponding price is the equilibrium price or market-clearing price, the quantity is the equilibrium quantity.

3) goods brought on by fads

4) Because supply shock is a sudden change of a good. Meaning if it is a negative shock, the equilibrium price and quantity of course will go down. And if it is a positive shock, vice versa of negative.

5) consumers are able to pay more so they can buy a product when rationing makes it unavailable

biological/genetic factors means they were born or predisposed to have something. nothing can really change it, and you can't really do much to "fix" it. it isn't something learned

these are the biological factors:

adrian is relatively tall and he is on the basketball team

(adrian can't ever stop being tall or force himself to be tall. likely one or both of his parents are tall as well and they passed on the tall gene. he probably does basketball because he is tall)

the rest are environmental/cultural factors. these are things that are taught to us. for example, cynthia wasn't born saving pocket money, her family most likely taught her this (environmental factor)

hope this !
