PROFIT MAXIMISATION AND IMPERFECT COMPETITION—AN APPLICATION OF QUADRATIC PROGRAMMING TO HORTICULTURE*

This paper discusses the determination of profit-maximising behaviour under conditions of imperfect competition in product and/or factor markets. After stating a quadratic programming model which restricts product demand and factor supply functions to a linear form, an empirical application to a New Zealand nursery firm is discussed. It is concluded that such quadratic programming models should have an important role to play in horticultural management
