Prominent features of differentiated product markets are segmentation and product proliferation that blurs the boundaries between segments. I develop a tractable demand model, the Ordered Nested Logit, which allows for over lap between neighboring segments. I apply the model to the automobile market where segments are ordered from small to luxury. I find that consumers, when substituting outside their vehicle segment, are more likely to switch to a neighboring segment. Accounting for such a symmetric substitution matters when evaluating the impact of new product introduction or studying the effect of subsidies on fuel-efficient cars.

"The central aim of this book is to consider to what extent changes in organisations and in the nature of jobs are compatible with the need, increasingly expressed by employees, for greater integration between work and family life. The book questions what sort of dilemmas modern and future employees face, in terms of shaping their careers and organising their lives at home. The authors formulate answers to these problematic questions by shedding light on relevant developments in the European labour markets, the European workplaces, in (flexible) working patterns, changing preferences for working hours and in gender relations at work.".
