Sharing Non-Anonymous Costs of Multiple Resources Optimally
In cost sharing games, the existence and efficiency of pure Nash equilibria
fundamentally depends on the method that is used to share the resources' costs.
We consider a general class of resource allocation problems in which a set of
resources is used by a heterogeneous set of selfish users. The cost of a
resource is a (non-decreasing) function of the set of its users. Under the
assumption that the costs of the resources are shared by uniform cost sharing
protocols, i.e., protocols that use only local information of the resource's
cost structure and its users to determine the cost shares, we exactly quantify
the inefficiency of the resulting pure Nash equilibria. Specifically, we show
tight bounds on prices of stability and anarchy for games with only submodular
and only supermodular cost functions, respectively, and an asymptotically tight
bound for games with arbitrary set-functions. While all our upper bounds are
attained for the well-known Shapley cost sharing protocol, our lower bounds
hold for arbitrary uniform cost sharing protocols and are even valid for games
with anonymous costs, i.e., games in which the cost of each resource only
depends on the cardinality of the set of its users
An Optimal Incentive System For Real Estate Agents
This article presents an alternative system for selling real estate. It overcomes the well-known deficiencies of the percentage commission system. In our system, the agent purchases the property from the seller and simultaneously receives a put option. The put option gives the agent the right to put the property back to the original owner. It is shown that this system has many of the desirable properties of a dealer system, while avoiding some of the problems that are inherent in that system.
Mergers, Investment Decisions and Internal Organisation
We analyse the effects of investment decisions and firms’ internal organisation on the efficiency and stability of horizontal mergers. In our framework synergies are endogenous and there might be internal conflict within merged firms. We show that often stable mergers do not lead to more efficiency and may even lead to efficiency losses. These mergers lead to lower welfare, suggesting that a regulator should be careful in assuming that possible efficiency gains of a merger will be effectively realised. Moreover, the paper offers a possible explanation for merger failures. ZUSAMMENFASSUNG - (Fusionen, Investitionsentscheidungen und unternehmensinterne Organisation) Wir analysieren die Auswirkungen von Investitionsentscheidungen und internen Organisationsstrukturen auf die Effizienz und Stabilität von horizontalen Firmenzusammenschlüssen. In unserer Untersuchung sind Synergien endogen und es können interne Konflikte in dem fusionierten Unternehmen auftreten. Es zeigt sich, dass "stabile" Fusionen häufig nicht zu mehr Effizienz, sondern sogar zu Effizienzverlusten führen können. Da solche Firmenzusammenschlüsse zu einer geringeren Wohlfahrt führen, sollte der Regulierer nicht ungeprüft annehmen, dass potentielle Wohlfahrtsgewinne auch immer tatsächlich erreicht werden. Außerdem bietet das Papier eine mögliche Erklärung für das Scheitern von Fusionen.Horizontal Mergers, Investment, Efficiency gains, Internal Conflict.
Regulation, competition, and liberalization
In many countries throughout the world, regulators are struggling to determine whether and how to introduce competition into regulated industries. This essay examines the complexities involved in the liberalization process. While stressing the importance of case-specific analyses, this essay distinguishes liberalization policies that generally are pro-competitive from corresponding anti-competitive liberalization policies
Engaging Residents in Low-Income Housing Communities to Volunteer and Earn an Economic Opportunity:
Low-income housing families have an acute need to gain an economic opportunity to build financial stability. Bella Communities' innovative resident volunteer engagement program, coupling the opportunity to earn rent credits through volunteering and promoting civic engagement, is rooted in the idea that the opportunity to earn an economic incentive through volunteering can fundamentally impact people's financial stability in two ways: first, by providing residents a solution to stitch a financial backstop to withstand emergencies and shortfalls, and, second, by fostering a sense of financial relief so that residents can pursue other endeavors to improve personal wellbeing and the community through volunteering. The architecture framework of our approach ensures optimal quality, efficiency, and effectiveness in our services. We believe the ReV-UP program adds value by being a "strong link within the chain" of asset-based community development
The Self-Enforcing Provisions of Oil and Gas Unit Operating Agreements: Theory and Evidence
This paper extends the existing theory and empirical investigation of unitization contracts. It highlights the importance of incentive-compatibility and self-enforcement and the bargaining problems faced in achieving viable, long-term contracts. We argue that only if the parties to a unitization contract have unit production shares that are the same as their cost shares will the contract be incentive compatible. Using a data base of sixty unit operating agreements, we measure the industry's actual behavior against the principles of production from a common pool. Our survey of units that have only one production phase and that are relatively homogeneous reveals that such equal sharing rules are always found and they appear to encourage the parties to behave optimally. In more complex units with multiple production phases and/or separate concentrations of oil and gas (gas caps) we find deviations from the theoretical ideal. In the case of multi-phase units, we find equal cost and production shares within phases, but not across phases. A pre-set trigger for shifting from one production phase to the next helps to maintain optimal behavior. For gas cap units, however, we generally do not find the equal sharing rule. Conflicts and rent dissipation follow as illustrated by the case of the Prudhoe Bay Unit. The paper describes the desirable contract rules for avoiding moral hazard. It also shows how the effects of those rules can be replicated in difficult situations.
