A clinical trial participant experiences a serious adverse event (SAE). What is the sponsor’s PRIMARY obligation?

What is the overriding principle in the conduct of any clinical trial?

Consider a firm whose marginal cost of producing additional output is $20, and who charges a price of $25. What is this firm’s markup factor?

All firms operating in a competitive market have cost functions:

Consider an industry where the sales of the largest six firms are: $10, $10, $8, $6, $4, and $2. a) [2 points] Calculate the four-firm concentration ratio as well as the Herfindahl-Hirschman Index (HHI) for this industry. b) [2 points] Adjust the distribution of sales among the industry shown above to highlight that HHI accounts for the distribution of sales among the largest firms, while the concentration ratio does not.  Calculate the new HHI and four-firm concentration ratio. (keep the total sales, number of firms, and four-firm concentration ratio the same as part a) c) [2 points] Adjust the distribution of sales among the industry shown above to highlight that HHI accounts for sales outside the largest firms. Calculate the new HHI and four-firm concentration ratio (keep the total sales and four-firm concentration ratio the same as part a, but you can change the number of firms)

Which of the following is NOT a potential source of monopoly power?

The sales in this market, from largest to smallest firm, are: $10, $5, $2, $2, $1. What is the industry’s four-firm concentration ratio?

Consider a firm where cost function is:

Each firm in a long-run perfectly competitive industry has a cost function of: , with a marginal cost of: . How much output does each firm product in the long-run, and what price results? (hint: you’ll need the long-run average cost as a function of q).

Consider a long-run perfectly competitive industry versus a long-run monopolistically competitive industry. a) [2 points] Which industry type has higher profits? b) [2 points] In which industry will cost and price be higher? If there is a difference, explain why. (note: I want an answer that explains the fundamental reason why a difference exists, if there is one.)
