We consider duopolists innovating and producing a good subject to network externalities, so that the reservation price of a consumer increases with aggregate consumption. The post-innovation network consists of two compatible sub-networks, with increased network valuation of the new product....

The extant economic and marketing literature on product line design mainly addresses firm's product decisions in conventional markets. However, many products demonstrate salient network externalities in their consumption, such as computers, software, telephone, telefax, and Internet routers. To...

We consider duopolists innovating and producing a good that is subject to network externalities, so that the reservation price for a consumer increases with aggregate consumption. The post-innovation network consists of two compatible sub-networks, with increased network valuation of the new...

Despite what we learn in law school about the “meeting of the minds,” most contracts are merely boilerplate -- take-it-or-leave-it propositions. Negotiation is nonexistent; we rely on our collective market power as consumers to regulate contracts’ content. But boilerplate imposes certain...

We introduce a racing model with multiple product generations, product innovation, spin-outs, and licensing. Industry conditions and innovation characteristics affect who wins the race and who markets the resulting product. Small firms market their innovations when they pioneer a new generation...

New and old products differ in two respects: quality and newness. Whereas a higher quality of a new product always benefits consumers, the newness itself benefits some consumers, but not others, and for some, it is even a disadvantage. We capture these features in a Hotelling model of...

In the last decades, technologies became more complex which increased the degree of uncertainty in R&D. To overcome the uncertainty, firms frequently engage in R&D collaborations, e.g., Research Joint Ventures (RJVs), and licensing agreements. While RJVs are well explored in the literature, very...

Licensing in a patent thicket allows firms to either avoid or resolve hold-up. Firms' R&D incentives depend on whether they license ex ante or ex post. We develop a model of a patent portfolio race, which allows for endogenous R&D efforts, to study firms' choice between ex ante and ex post...

The paper introduces preference persistence into a dynamic discrete choice model of demand for durables. This persistence may arise, for example, when the products can be categorized into a few number of formats, which involve special knowledge, maintenance and upgrade. The standard optimal...

New and old products differ in two respects: quality and newness. Whereas a higher quality of a new product always benefits consumers, the newness itself benefits some consumers, but not others, and for some, it is even a disadvantage. We capture these features in a Hotelling model of Over-...
