Describe the Nature of the Concert as a Public Good

First paragraph write about (make sure you answer all questions): A famous singer plans to perform a concert at a football stadium in the heart of a large city. The stadium has several high-rise buildings around it and hundreds of people in the upper floors of these buildings can potentially see inside the stadium.
Step 2 Discuss the distribution and delivery of public goods.
Address the following in your response:
Explain the "free-rider" problem in the context of this performance.
Describe the nature of the concert as a public good.
If you were in charge of ticket sales for this concert, how would you respond to a situation in which you had 1000 tickets left over the day before the show?
What would be your plan to maximize profits? How can external benefits be realized through the delivery of a public good or service?
Second paragraph: A student responded (below) use these instructions to respond: IN, addition to other comments you may have, address the following in your response posts:
What potential benefits do other students foresee as a result of this "free-rider" issue?
Do those benefits outweigh the financial loss being disputed?
Use any personal experience, if appropriate, to help support or debate other students' posts. If differences of opinion occur, debate the issues professionally and provide examples to support your opinions.
Students response: 
In this case with the concert at the stadium the people in the upper floors of the high-rise buildings will receive the benefits from the resources or services without contributing or paying for the cost of the benefit, this would be consider “free-rider.”
The nature of the concert as a public good is known as the natural monopoly goods. It’s a good that is non-rivival but excludable. With a concert more people don’t decrease the enjoyment of the others; also people can be excluded if they don’t pay for the benefits of the service.
If I had 1000 tickets left a day before the concert I would probably give an incentive to sale these tickets by using the free rider program, which is get two tickets for the price of one. Someone will be able to benefit from the concert without paying the full price.
I would reduce direct cost, negotiate lower prices with my suppliers in order to maximize by profits.
