The land assembly problem revisited

As in the standard land assembly problem, a developer wants to buy two adjacent blocks of land belonging to two di¤erent owners. The value of the two blocks of land to the developer is greater than the sum of the individual values of the blocks for each owner. Unlike the land assembly literature, however, our focus is on the incentive that each lot owner has to delay the start of negotiations, rather than on the public goods nature of the problem. An incentive for delay exists, for example, when owners perceive that being last to sell will allow them to capture a larger share of the joint surplus from the development. We show that competition at point of sale can cause equilibrium delay, and that cooperation at point of sale will eliminate delay.

Chasing patents

We examine the problem faced by a company that wishes to purchase patents in the hands of two di¤erent patent owners. Complementarity of these patents in the production process of the company is a prime e¢ciency reason for them being owned (or licenced) by the company. We show that this very same complementarity can lead to patent owners behaving strategically in bargaining, and delaying their sale to the company. When the company is highly leveraged, such ine¢cient delay is limited. Comparative statics results are also obtained. Relevant applications include assembly of patents for drug treatments from the human genome, and land assembly.
