Multi-Purpose Consumption and Functional Differentiation: Why has the Vibrant Galleria replaced the Good Old Fashioned Department Store?
A very striking change in product selection over the last century has been the increased degree of specialisation of durable goods. To analyse these changes this paper introduces a new form of product differentiation called functional. It is shown that when a homogeneous population demands multiple locations (rather than consumers being heterogeneous) several standard results are reversed. A monopoly has an incentive to offer excessively specialised goods and delay innovation. It is in a duopoly that product characteristics will be efficient. Entry of a third firm will be more profitable in the fringes. Furthermore entry results in too much variety. Finally, the paper presents a novel argument in favour of bundling.
