Answer:
Your opportunity cost of attending a game compared with the opportunity cost facing a college student 10 years ago is:
A) higher, because more games are televised today.
Opportunity costs are the cost of choosing one alternative from another.
In this case, when college students attend college football games they are unable to do other activities, not only while they are at the stadium or going to the stadium, but they are not able to purchase other goods. The cost of those alternatives that are lost are higher now because many college football games are televised now, before if you wanted to see a game you had to go to the game. So a student is now able to watch the game while doing other activities, or saving money for buying something else.
Can this change in opportunity cost account for the decline in college football​ attendance?
B) ​Yes, because these changes increase the opportunity cost of watching football games in person.
Even though opportunity costs do not involve actual cash payments, they are still important and individuals do consider them when they are choose one option over another. E.g. imagine if you had to choose between spending a considerable amount of money by attending a game (ticket, gas, beverages, etc.) or watching that game on TV and buying a few clothes instead or going on a date, etc. What option would you choose?
