Kevin Techer (University Jean Monnet Saint-Etienne) will present the paper “Hazardous waste transportation: a cost allocation analysis” on May 22nd, 2024, at 10:30 AM, in room QA406.

Abstract:   

This paper studies hazardous waste transportation problems. Due to their dangerous nature, the transportation of such waste implies a risk of incident having irreversible consequences on the environment. This problem has lead to a body of legal statutes that monitor the generation, storage and transportation of hazardous waste. Assuming that the transport of hazardous waste is done in a cooperative manner on a transport network, this paper investigates how to share the cost of maintaining such network among the involved agents. We analyze the hazardous transportation problem from the viewpoint of axiomatic analysis. We consider several axioms that are interpreted through different environmental law principles and provide a characterization of a new allocation rule: the responsibility rule. Then we show that the responsibility rule coincides with the multi-choice Shapley value of an appropriate multi-choice game.

Artem Razumovskii (CERGE-EI) will present the paper “Interim Deadline for Procrastinators” on May 8th, 2024, at 10:30 AM, in room QA406.

Abstract:   

People are partially time inconsistent and many have difficulties committing to a detailed schedule for a project. I study optimal interim deadlines and how they affect the behavior and resulting welfare of the present-biased agent. I consider a model in which there are three types of agent in terms of how the agent understands her present bias: naive, sophisticated, and partially-sophisticated. For each type, there is a unique design for an exogenous interim deadline that maximizes the agent’s welfare. However, only the sophisticated agent would self-impose an optimal interim deadline, while the naïve agent would not apply a self-imposed deadline at all. The partially-sophisticated agent sets a nonoptimal self-imposed deadline and can even decrease her own welfare by imposing it. The main result is that the partially-sophisticated agent who is relatively less present-biased would decrease her own welfare by using a self-imposed deadline, and the partially-sophisticated agent who is relatively more present-biased would increase her welfare given the same degree of sophistication.

Abstract:   

The paper introduces a new coalitional game with transferable utility — called a two-sided platform game. The participation of the platform user on one side benefits the other side, and the platform can be established if and only if there is more than one entrepreneur. Well-known point solutions and set solutions are investigated. It turns out that the kernel and the nucleolus coincide, and both the Shapley value and the nucleolus have simple expressions. The paper sheds light on platforms and antitrust issues. When there is more than one platform entrepreneur, the utility share of each entrepreneur is relatively low in both point solutions.
