Tastes, production, labor markets, financial markets, and competition have become highly globalized; financial and economic crises have become more frequent, and the risks of doing business have increased in a world economy that has become more sluggish (growing less rapidly than in past decades). Thoroughly recognizing and highlighting this new business environment, Managerial Economics in a Global Economy examines how firms reach optimal managerial decisions in the face of these modern constraints. Managerial Economics in a Global Economy synthesizes economic theory, decision sciences, and business administration to help instructors train students on how managerial deccisions are actually made in the modern, globalized world. Theory is explained clearly and the applications are numerous, real, and relevant. A global perspective permeates the presentation- examples, data and theory- to help illustrate how local economic decision making is now inescapably global.
