Resource Allocation Among Competing Innovators

Many innovative products are designed to satisfy the demand of specific target consumers; thus, the innovators will inevitably compete with each other in the product market. We investigate how a profit-maximizing principal should properly allocate her limited resources to support the innovations of multiple potentially competing innovators. We find that, as the available resources increase, the optimal diversification of investment may first increase and then decrease. This interesting nonmonotone pattern is driven by a trade-off between the risk of innovation failure and rent dissipation because of competition. Using this framework, we also analyze a nonprofit principal seeking to maximize the total number of successful innovations, the probability of at least one innovator succeeding, consumer surplus, and total social welfare. A nonprofit principal tends to invest more diversely compared with a for-profit counterpart. This paper was accepted by Sridhar Tayur, entrepreneurship and innovation.

A Virtuous Circle of Governance Contests with Externalities

Governments create contests to allocate resources to stakeholders, e.g., grants, contracts. The actions of these stakeholders can generate a positive externality for themselves—the contest winner can attract additional outside funding and donations from third-parties who want to jump on the winner’s bandwagon. Herein we examine the externalities arising from these contests created by governance and their impact on a virtuous circle of governance contests. Among various conditions that make governance virtuous, we focus on the equilibrium expected payoffs of stakeholders, the difference in them, and the rent-dissipation rates. Our study shows that the impact of externalities on the efficiency of governance depends on two key factors: (i) the choice of governance contests, the player-externality and the winner-externality, and (ii) the relative efficiency of stakeholders’ efforts.

On a Fallacy in the Coase Theorem and the Theorem of Transaction Costs Substitution

This paper first presents a historical account of the origin of the Coase Theorem. It then elaborates its significance in explaining the working of economic institutions. After expounding the concepts of transaction cost and rent dissipation, it points out an error in the Coase Theorem. Lastly, the paper propounds the Theorem of Transaction Costs Substitution as an extended and general version of the Coase Theorem.
