How important are chromosomes in our development? We know that chromosomes transmit all the information as to who we are to become both physically and chemically, and they pass on important characteristics such as handedness, height, weight and hair color – but how important are they to helping us become who we are? Is nature more important than nurture? Is there anything we can do that changes our chromosomes? Could this help or hinder us in our development? What happens when one of these chromosomes goes awry?

Note* - You must have 250 words in your response and cite any sources that you use to answer the question. (it might be easier to copy information online then citing it afterwards)

There are two individuals, Scooter and the Big Man. There are two different streets in which each

individual can choose to live: Tenth Avenue and Thunder Road. It costs nothing to live or move

into each location. However, the probability of getting sick (and losing $100 to medical bills) on

Tenth Avenue is 0.25, while the probability of getting sick on Thunder Road is 0.5. Each individual

is endowed with $100 and faces a utility function of

U

=

√

w

where w is wealth. Scooter values living

on Thunder Road at $80 and living on Tenth Avenue at $40. The Big Man values living on Tenth

Avenue at $80 and living on Thunder Road at $40. Each person can choose where he wants to live

only once.

(a) Assuming each individual only cares about maximizing expected utility, where will each indi-

vidual want to live?

(b) Scooter and the Big Man can buy insurance for their medical bills from a firm. The firm can

break even, but cannot expect to make a positive profit because of perfectly competitive markets

and entry and exit. Due to a failure to collect accurate information, the firm hedges its bets

and assumes each individual will choose to live on the risky Thunder Road and values living on

Thunder Road at $80. What is the premium (p) the firm will charge each individual?

(c) Assume the firm charges each individual the premium as found in part b. Still assuming Scooter

and the Big Man only care about maximizing their expected utilities, what will each individual

choose to do? That is, where will they live? Will they choose to buy insurance?

(d) What is the name of the market failure that takes place in part c? How does it apply here?

(e) The firm hires a consultant who is good at acquiring accurate market information. Assume the

firm knows that Scooter values living on Thunder Road at $80 and the Big Man values living

on Tenth Avenue at $80. What premium should the firm charge each individual?

(f) Assume the firm charges the premiums found in part e. Still assuming Scooter and the Big

Man only care about maximizing their expected utilities, what will each individual choose to

do? That is, where will they live? Will they choose to buy insurance?

(g) Did the results from parts e and f solve the market failure identified in part e? If so, how? If

not, why not?
