Relying on the agent in charge of production for project evaluation
I study the optimal project choice when the principal relies on the agent in charge of production for project evaluation. The principal has to choose between a safe project generating a fixed revenue and a risky project generating an uncertain revenue. The agent has private information about the production cost under each project but also about the signal regarding the profitability of the risky project. If the signal favoring the adoption of the risky project is goods news to the agent, integrating production and project evaluation tasks does not generate any loss compared to the benchmark in which the principal herself receives the signal. By contrast, if it is bad news, task integration creates an endogenous reservation utility which is type-dependent and thereby generates countervailing incentives, which can make a bias toward either project optimal. Our results can offer an explanation for why good firms can go bad and a rationale for the separation of day-to-day operating decisions from long-term strategic decisions stressed by Williamson.Information flows, countervailing incentives, multitasking, asymmetric information, innovations
Failure to collude in the presence of asymmetric information
In this paper, we design the optimal contract when two agents can collude under asymmetric information. They have correlated types, produce complementary inputs and are protected by limited liability. Therefore, a joint manipulation of reports allows them to internalize informational and productive externalities. We show that by taking advantage of the transaction costs created by asymmetric information, even though they collude, the principal can achieve the outcome without collusion regardless of the sign and the degree of correlation. In particular, the principal can implement a non-monotonic quantity schedule in a collusion-proof way while this is impossible if collusion occurs under complete information.Asymmetric information, transaction costs, limited liability, side-contract, collusion-proofness, virtual cost
A simple access pricing rule to achieve the Ramsey outcome for interconnected networks
This paper considers a general and informationally efficient approach to determine the optimal access pricing rule for interconnected networks. It shows that there exists a simple rule that achieves the Ramsey outcome as the unique equilibrium when networks compete in linear prices without network-based price discrimination. The approach is informationally efficient in the sense that the regulator is required to know only the marginal cost structure, i.e. the marginal cost of making and terminating a call. The approach is general in that access prices can depend not only on the marginal costs but also on the retail prices, which can be observed by consumers and therefore by the regulator as well. In particular, I consider the set of linear access pricing rules which includes any fixed access price, the Efficient Component Pricing Rule (ECPR) and the Modified ECPR as special cases. I show that in this set, there is a unique rule that implements the Ramsey outcome as the unique equilibrium independently of the underlying demand conditions.Networks, Access Pricing, Interconnection, Competition Policy
When Is the Optimal Lending Contract in Microfinance State Non-Contingent?
Whether a microfinance institution should use a state-contingent repayment or not is very important since a state-contingent loan can provide insurance for borrowers. However, the classic Grameen bank used state non-contingent repayment, which is puzzling since it forces poor borrowers to make their payments even under hard circumstances. This paper provides an explanation to this puzzle. We consider two modes of lending, group and individual lending, and for each mode we characterize the optimal lending and supervisory contracts when a staff member (a supervisor) can embezzle borrowers' repayments by misrepresenting realized returns. We identify the main trade-off between the insurance gain and the cost of controlling the supervisor's misbehavior. We also found that group lending dominates individual lending either by providing more insurance or by saving audit costs.
Bundling electronic journals and competition among publishers
Site licensing of e-journals has been revolutionizing the way academic information is distributed. However, many librarians are concerned about the possibility that publishers might abuse site licensing by practicing bundling. In this paper, we analyze the private and social incentives for the publishers to use bundling in the context of STM electronic journal market. In the short run in which the number of journals is exogenously given, we find a strong conflict between the two incentives: each publisher finds bundling optimal and bundling increases the industry profit but reduces social welfare. However, in the long run we find that publishers might have higher incentives to introduce new journals under bundling than without bundling and, in this case, bundling can reduce the industry profit while increasing social welfare. Finally, we examine publishersā incentive to provide links to the websites of the rival publishers under bundling and show that even asymmetric publishers have incentive to interconnect.Bundling, site licensing, interconnection, merger
Optimal second-degree price discrimination and arbitrage: On the role of asymetric information among buyers
The traditional theory of monopolistic screening tackles individual self-selection but does not address the possibility that buyers could form a coalition to coordinate their purchases and to reallocate the goods. In this paper, we design the optimal sale mechanism which takes into account both individual and coalition incentive compatibility focusing on the role of asymmetric information among buyers. We show that when a coalition of buyers is formed under asymmetric information, the monopolist can do as well as when there is no coalition. Although in the optimal sale mechanism marginal rates of substitution are not equalized across buyers (hence there exists room for arbitrage), they fail to realize the gains from arbitrage because of the transaction costs in coalition formation generated by asymmetric information.Monopolistic screening, coalition incentive compatibility, asymetric information, transaction costs
Money, fame and the allocation of talent: Brain drain and the institution of science
The earning structure in science is known to be flat relative to the one in the private sector, which could cause a brain drain toward the private sector. In this paper, we assume that agents value both money and fame and study the role of the institution of science in the allocation of talent between the science sector and the private sector. Following works on the Sociology of Science, we model the institution of science as a mechanism distributing fame (i.e. peer recognition). We show that since the intrinsic performance is less noisy signal of talent in the science sector than in the private sector, a good institution of science can mitigate the brain drain. We also find that providing extra monetary incentives through the market might undermine the incentives provided by the institution and thereby worsen the brain drain. Finally, we study the optimal balance between monetary and non-monetary incentives in science.Fame, Science, Brain Drain, Incentives, Asymmetric Information
Bundling and Competition for Slots: On the Portfolio Effects of Bundling
We consider competition among sellers when each of them sells a portfolio of distinct products to a buyer having limited slots. We study how bundling affects competition for slots. Under independent pricing, equilibrium often does not exist and hence the outcome is often inefficient. When bundling is allowed, each seller has an incentive to bundle his products and an efficient equilibrium always exists. Furthermore, in the case of digital goods, all equilibria are efficient if slotting contracts are prohibited. We also identify portfolio effects of bundling and analyze the consequences on horizontal mergers. Finally, we derive clear-cut policy implications.
