Answer to Question 1
Without enforceable property rights, entrepreneurs lose the incentive to take on risk because they are not assured ownership of their resources. Economic growth suffers as a result. Failure to protect intellectual property rights has a similar impact. If the benefits of technological advances are shared with all firms, each individual firm has little incentive to invest in the costly research and development necessary for technological progress to continue.
Answer to Question 2
No, the company is not maximizing profit because marginal revenue is not equal to cost. In fact, the cost of the last unit produced (15) is greater than the revenue that the firm gained from its sale. Thus, the firm lost money on the last unit sold. To maximize profits, the firm needs to lower its level of output.
