Three candidates to be the next WHO Director-General remain: Tedros Adhanom Ghebreyesus, David Nabarro, and Sania Nishtar. The World Health Assembly's ultimate choice will lead an Organization facing daunting internal and external challenges, from its own funding shortfalls to antimicrobial...

Inadequate financial resources are a major driver for poor health. Financial insecurity contributes to health inequities in mutually reinforcing ways, with some effects lasting years. Fostering financial security to reduce the likelihood or magnitude of such pressures would have significant...

The West African Ebola epidemic is a pivotal moment for the global health system. Just as the depth of the crisis ultimately spurred an unprecedented response, the failures of leadership demand innovative reforms. This analysis offers a template for these reforms, responding to the profound...

In this paper we study consistency in the context of additive cost sharing mechanisms. We contrast an extremely weak notion of consistency with the standard definition, which we denote strong consistency. First we show that many well known CSMs are consistent in both senses: Aumann-Shapley,...

We provide several new characterizations of well known cost sharing methods (CSMs) as maxima of linear (or convex) functionals. For the Shapley-Shubik method the characterization has an interpretation in terms of randomly ordered agents choosing their most preferred CSM, while the...

We consider the social norms of repeated matching games in the presence of finite probability trembles and show that such norms must be subgame perfect along the equilibrium path but need not be subgame perfect off the equilibrium path. This is consistent with the well known experimental results...

In this paper we develop a unified framework for the study of additive cost sharing methods. We show that any additive cost sharing method satisfying the dummy axiom can be generated by a (possibly infinite) convex combination of path generated methods. We also show that the set of scale...

Using a new representation theorem for additive cost sharing methods as sums of path methods, we show that many of the standard additive cost sharing methods (Aumann-Shapley, Shapley Shubik, and Serial Cost) are consistent. These results follow directly from a simple sufficient condition for...

We consider three new axioms for surplus sharing problems. The first is strong monotonicity which says that workers should be rewarded for increases in productivity and the second says that productive workers should receive some compensation. The third requires that the surplus sharing rule...
