The correct answer is: Profit maximisation.

Traditional economic theory assumes that entrepreneurs make decisions so as to maximise profit. More recently, as companies have grown and the managers have become more divorced from ownership by shareholders other theories have been suggested. These include Baumol's theory of sales maximisation and Williamson's theory that managers need only attain a minimum level of profit to keep shareholders content after which they may follow their own objectives. Cyert and March on the other hand suggested that no one objective is followed but a series of objectives which are a compromise.
