o     If Odds Ratio = 1
o     If Odds Ratio < 1
C. You toss a coin, if head comes, you are given Rs. 200 and if tail comes, you have to pay Rs. 200. Will you play this game or not? Give your answer with brief explanation.
(Marks: 3+3+4)
Answers : A)

Risk and Uncertainty : Risk is when an outcome may or may not occur but its probability is known while uncertainty is when an outcome may or may not occur but its probability is not known.

Answers : B)

1)      For risk neutral person

o     If Odds Ratio > 1, then he will definitely buy
o     If Odds Ratio = 1, then he will be indifferent
o     If Odds Ratio < 1, then he might not buy as OR < 1

2)      For risk averse person

o     If Odds Ratio > 1, then in this case as well he might decide not to buy.
o     If Odds Ratio = 1, then he will definitely not buy
o     If Odds Ratio < 1, then he will definitely not buy

3)      For risk loving person

o     If Odds Ratio > 1, then he will definitely buy
o     If Odds Ratio = 1, then he will definitely buy
o     If Odds Ratio < 1, then in this case as well he might decide to buy.


Answers : C)

The tossing of a coin and the probability of a head appearing is 50% i.e. the odds of success are fair.  So the option of OR < 1 and OR > 1 is not there. The only possibility is OR = 1 which means that the chances are not that bad. Now it depends on the fact that whether I am a risk averse, risk neutral or risk loving person. In case of fair odds both risk loving and risk neutral person might decide to play. So I will play this game as the amount of money involved is not that much and as far as my perception of it is concerned the marginal benefit of gaining 200 Rs is perceived by me as more than the marginal cost of losing the 200 Rs. So I would definitely play this game. Moreover the excitement of winning might overshadow my rational judgement and I would definitely decide to play by being carried away by excitement.
