The Decision ProcessThe Decision Process •Where does economics fit in?•Establish Objectives… what is our goal?•Define the Problem…Competition is fierce...•Identify factors that affect the problem… Other firms appear to produce a comparable product at lower costs…•Specify Alternative Solutions… Should we expand our plant size or decrease our plant size or improve our product techniques?•Collect Data and Other Information… Do bigger firms dominate the industry? or smaller firms? Have higher quality firms performed well?•Evaluate and Screen Alternatives… Bigger firms are in better financing (need clarity) shape. Smaller firms are being (need clarity) customers are buying which ever costs the least.•After further investigation of the best, cost less.•Implement best alternatives and monitor results…

Theory of the Firm Expected Value Maximization
Owner-managers maximize short-run profits. Primary goal is long-term expected value
maximization. Constraints and the Theory of the Firm
Resource constraints. Social constraints.
Limitations of the Theory of the Firm Alternative theory adds perspective. Competition forces efficiency. Hostile takeovers threaten inefficient managers.

Goal of the Firm
© 2009, 2006 South-Western, a © 2009, 2006 South-Western, a part of Cengage Learningpart of Cengage Learning
Theory of the Firm
Objective 1: Maximize stock prices. Maximize the present value (PV) of the expected future profits – maximize PV over time…
Value of the Firm = present value of future profits. Expected profits are discounted, which puts more weight on profits in the near term than the long term. Any new information revealed about a company will immediately impact their stock price. Positive reports increase the prospects of future expected profit (stock prices rise), negative reports typically negatively impact the outlook of future profits (stock prices fall).
