I study a network based mechanism of norm enforcement in a community where agents play a Prisoner’s Dilemma with changing partners. Agents may choose a number of close friends. Communication to close friends within the network enforces cooperation. In a world with noiseless communication, it is optimal that each agent has close contacts to all other network members. Moreover, it is optimal to h...

OBJECTIVE To assess the effectiveness of midwives administering misoprostol to women with incomplete abortion seeking post-abortion care (PAC), compared with physicians. DESIGN A multicentre randomised controlled equivalence trial. The study was not masked. SETTINGS Gynaecological departments in two hospitals in a low-resource setting, Kenya. POPULATION Women (n=1094) with incomplete abor...

In this paper we present a model of the multiple unit, single item procurement network formation problem in environments with incomplete information (MPNFI). For this we first develop the structure of the procurement network formation problem within Myerson’s framework for cooperative games with incomplete information [1]. Using this framework we then investigate the non-emptiness of the incent...

We address the question of whether price of stability results (existence of equilibria with low social cost) are robust to incomplete information. We show that this is the case in potential games, if the underlying algorithmic social cost minimization problem admits a constant factor approximation algorithm via strict cost-sharing schemes. Roughly, if the existence of an α-approximate equilibri...

299 cases of incomplete abortions were admitted to jahanshah saleh hospital, razi medical school university of tehran during the period of october 10, 1973 to november 24, 1974. all were treated with single dilatation and curettage. the patient groups were roughly half outpatient and half inpatient. the information was recorded on standard forms and computed by the international fertility resea...
