find and discuss articles about firms that illustrate these different types of costs in the real world: historical costs, accounting costs, opportunity costs, long run costs, short run costs, transaction costs, information costs and coordination costs. (Note: you will probably need to use more than one article to be able to discuss all of these different costs.) Choose two of the ways companies cut cost and explain what cost information would be used to implement that decision. Defend your answer and cite your sources.
