There are two types of farming tractors on the market, the FT250 and the FT500. The only difference between the two is that the

Answer:

The statistical value farmers place on avoiding a tractor accident is $200,000.

The statistical value farmers place on avoiding a tractor fatal accident is $15,000,000.

Step-by-step explanation:

We have two tractors, with different probabilities of non-fatal and fatal accidents, and also different prices.

We will use this price difference to estimate how it is valued a non-fatal and fatal accident.

The difference in prices is:

\Delta P=125,000-137,000=-12,000

The expected non-fatal accidents for each tractor is

FT500\rightarrow 1/10=0.1\\\\FT250 \rightarrow 1/25=0.04

The difference in expected non-fatal accidents is:

\Delta NFA = 0.10-0.04=0.06

For a 6% more chance of having an accident, the farmers discounts 12,000 for the price of the less safe of the tractors.

Then, we can calculate the statistical value farmes place on avoiding a tractor accident as:

V_{NFA}=\frac{-\Delta P}{\Delta NFA} =\frac{12,000}{0.06} =200,000

The expected fatal accidents for each tractor is

FT500\rightarrow 1/1,000=0.0010\\\\FT250 \rightarrow 1/5,000=0.0002

The difference in expected fatal accidents is:

\Delta NFA = 0.0010-0.0002=0.0008

For a 0.08% more chance of having an fatal accident, the farmers discounts 12,000 for the price of the less safe of the tractors.

Then, we can calculate the statistical value farmes place on avoiding a tractor accident as:

V_{FA}=\frac{-\Delta P}{\Delta FA} =\frac{12,000}{0.0008} =15,000,000
