We will derive a two-state put option value in this problem. data: s0 = 180; x = 190; 1 + r = 1.1. the two possibilities for st are 210 and 110.

a.
the range of s is 100 while that of p is 80 across the two states. what is the hedge ratio of the put? (negative value should be indicated by a minus sign. round your answer to 2 decimal places.)

Upscale hotels in the united states recently cut their prices by 20 percent in an effort to bolster dwindling occupancy rates among business travelers. a survey performed by a major research organization indicated that businesses are wary of current economic conditions and are now resorting to electronic media, such as the internet and the telephone, to transact business. assume a company's budget permits it to spend $5,000 per month on either business travel or electronic media to transact business. graphically illustrate how a 20 percent decline in the price of business travel would impact this company's budget set if the price of business travel was initially $1,000 per trip and the price of electronic media was $500 per hour. suppose that, after the price of business travel drops, the company issues a report indicating that its marginal rate of substitution between electronic media and business travel is 1. is the company allocating resources efficiently? explain.
