Managerial and Behavioural Theories
It was only in the 1960s that the neo-classical theory of the firm was seriously challenged by alternatives such as managerial and behavioral theories. Managerial theories of the firm, as developed by William Baumol (1959 and 1962), Robin Marris (1964) and Oliver E. Williamson (1966), suggest that managers would seek to maximise their own utility and consider the implications of this for firm behavior in contrast to the profit-maximising case. (Baumol suggested that managers’ interests are best served by maximising sales after achieving a minimum level of profit which satisfies shareholders.) More recently this has developed into ‘principal–agent’ analysis (e.g. Spence and Zeckhauser and Ross (1973) on problems of contracting with asymmetric information) which models a widely applicable case where a principal (a shareholder or firm for example) cannot costlessly infer how an agent (a manager or supplier, say) is behaving. This may arise either because the agent has greater expertise or knowledge than the principal, or because the principal cannot directly observe the agent’s actions; it is asymmetric information which leads to a problem of moral hazard. This means that to an extent managers can pursue their own interests. Traditional managerial models typically assume that managers, instead of maximising profit, maximise a simple objective utility function (this may include salary, perks, security, power, prestige) subject to an arbitrarily given profit constraint (profit satisficing).

Famous quotes containing the words behavioural and/or theories:
“The tabloids are like animals, with their own behavioural patterns. There’s no point in complaining about them, any more than complaining that lions might eat you.”
—David Mellor (b. 1949)
“The real trouble about women is that they must always go on trying to adapt themselves to men’s theories of women, as they always have done. When a woman is thoroughly herself, she is being what her type of man wants her to be. When a woman is hysterical it’s because she doesn’t quite know what to be, which pattern to follow, which man’s picture of woman to live up to.”
—D.H. (David Herbert)
