Question 5

Situation 33-1 Suppose that the equation that represents the expected benefits of burglary for a given prospective criminal is as follows:
EB = Ps x Loot
The criminal's cost equation is as follows:
EC = [Pp x (I + F)] +  AC
Where:
EB is the expected benefits of burglary
Ps is the probability of successfully burglarizing a house
Loot is the dollar take from the burglary  
EC is the expected costs of burglary
Pp is the probability of imprisonment
I is the income the criminal gives up if caught and imprisoned
F is the dollar value the criminal puts on freedom
AC is the anguish cost of committing a burglary
Refer to Situation 33-1.  If the prospective criminal sets the following values:
Ps = 50 percent
Loot = $30,000
Pp = 10 percent
I = $10,000
F = $25,000
AC = $5 ,000
The prospective criminal's expected benefit from committing the burglary is ______________ and his expected cost of committing the burglary is _______________.  Economic theory tells us that under these circumstances, the prospective criminal ______________ commit the burglary.

Accepted Answer

A) $15,000; $8,500; will 
B) $15,000; $8,500; will not
