Review the below described Concentration strategies in the textbook. These are strategies that involve trying to successfully compete only within a single industry. There are three concentration strategies:

  • Market penetration involves trying to gain additional share of a company’s existing markets using existing products. Often companies will rely on advertising to attract new customers with existing markets.
  • Market development involves taking existing products and trying to sell them within new markets. One way to reach a new market is to enter a new retail channel or geographic areas.
  • Product development involves creating new products to serve existing markets.

Select one of these and find an article that describes a company that has successfully used this strategy.   Identify the company and provide an analysis of what the company has done. Also, from your own learning from the class, assess what the company did to make this successful.

Consider the Bertrand duopoly model with differentiated products. Firm 1's demand function is q1 = 1/2-(P1-P2)/3, and Firm 2's demand function is q2 = 1/2 - (P2-P1)/3. Firms have identical marginal costs c>0. a) Derive firms' best replies and draw them. b) Compute the Bertrand equilibrium prices, quantities, and profits (show all the steps of the derivation)

Parts A and B contain hypothetical quotes by two unnamed politicians. Using information from this course/textbook, explain why each quote reflects faulty economic reasoning. (Each quote might contain parts that are at least partially true, but when combined, the overall statement is not true).

  1. “If we limit the price of drug XYZ to one-third of its current level, we will be harming the very patients we claim to be helping. The company that produces XYZ spent millions of dollars developing and testing this drug, and will almost certainly stop producing it once the price ceiling is implemented.” (Note: assume that this drug is still protected by its patent).
  2. “My opponent in Part A is nuts; the company will continue producing XYZ. No one will be hurt by this life-saving legislation, except for the company and its greedy managers and shareholders.” Hint: Can you identify another group of people (stakeholders) who might be hurt by this legislation?

  1. One benefit claimed by third-party logistics provider is that they can provide access to critical performance and operational data. From the supply chain information system perspective, what do you think these data could be? How these data may impact supply chain performance? Are these data really critical to a firm? Also, why can 3rd party logistics providers collect these data?
  1. ERP system started in the 1990s and has quickly become a necessity for almost all companies. People claim that the ERP system has brought enormous benefits to organizations, from improving competition and efficiency to enhanced collaboration. This is the reason why almost all companies are working (or planning to work) with an ERP system.

However, the study has shown that the failure rate of the ERP system is significant. The failure rate ranges from 50% to 70% depends on different studies. If ERP is such a great system, people must have accumulated sufficient experience over decades of history. Why do you think there is still such a high failure rate?

Problem 17-02
Interest Rate Parity

The nominal yield on 6-month T-bills is 7%, while default-free Japanese bonds that mature in 6 months have a nominal rate of 4%. In the spot exchange market, 1 yen equals $0.011. If interest rate parity holds, what is the 6-month forward exchange rate? Round the answer to five decimal places. Do not round intermediate calculations.

Thanks for the help!
