タイトル：Competing Teams in Large Markets: Free Entry Equilibrium with (Sub-)Optimal Contracts
アブストラクト：In this paper, we formalize a market with a large number of competing production teams following Alchian and Demsetz (1974). We allow for wide-spread externalities which can affect players’ payoffs. These externalities include changes in market conditions and pollutions, and may generate a variety of equilibrium outcomes. There are finite types of atomless players, who can form team-firms with finite memberships using available technologies. Given an arbitrary set of feasible partnership contracts for each team type, we consider free entry equilibrium as our equilibrium concept—in a free entry equilibrium, no team type can attract its members from other teams by proposing any implementable partnership contract. Furthermore, in a free entry equilibrium, players of the same type may have different payoffs—unequal treatment of equals. We show that as long as each firm type’s implementable payoff set is compact and continuous in externality variables, there exists a free entry equilibrium. We provide several applications of our results.

タイトル："Forced Displacement, Mental Health, and Child Development: Evidence from the Rohingya Refugees"
アブストラクト：Forced displacement is a major driver of mental disorders among refugees worldwide. Poor mental health of adult refugees, particularly mothers, is also considered a risk factor for the psychological well-being and development of their children. In this study, we experimentally examine the extent to which a multifaceted psychosocial program improves the mental health of refugee mothers, and facilitates growth and development among children under the age of two. In partnership with BRAC, we ran a cluster randomized controlled trial on 3,500 Rohingya mother-child dyads in refugee camps in Bangladesh. Participants were given weekly psychosocial support for 44 weeks through peer volunteers, which includes psychoeducation and parenting support for mothers and play activities for both mothers and children. The intervention was largely successful and led to: (i) reductions in the psychological trauma and depression severity of mothers and children, (ii) improvements in communication, gross-motor, and problem-solving skills of children, and (iii) reductions in stunting and severe stunting. The intervention cost about $1 per dyad per week and is currently being scaled up in refugee camps in Bangladesh, where about seventeen thousand mother-child pairs now benefit from it.
