  text: 'We explore how competition between physicians affects medical service provision.
    Previous research has shown that, without competition, physicians deviate from
    patient‐optimal treatment under payment systems like capitation and fee‐for‐service.
    Although competition might reduce these distortions, physicians usually interact
    with each other repeatedly over time and only a fraction of patients switches
    providers at all. Both patterns might prevent competition to work in the desired
    direction. To analyze the behavioral effects of competition, we develop a theoretical
    benchmark that is then tested in a controlled laboratory experiment. Experimental
    conditions vary physician payment and patient characteristics. Real patients benefit
    from provision decisions made in the experiment. Our results reveal that, in line
    with the theoretical prediction, introducing competition can reduce overprovision
    and underprovision, respectively. The observed effects depend on patient characteristics
    and the payment system, though. Tacit collusion is observed and particularly pronounced
    with fee‐for‐service payment, but it appears to be less frequent than in related
    experimental research on price competition. '

  text: 'This paper studies welfare consequences of consumer-side market transparency
    with endogenous entry of firms. Different from most studies, we consider the unique
    symmetric entry equilibrium, which is in mixed strategies. We identify two effects
    of market transparency on welfare: a competition effect and a novel market-structure
    effect. We show, surprisingly, that for almost all demand functions the negative
    market-structure effect eventually dominates the positive competition effect as
    the market becomes increasingly transparent. Consumer-side market transparency
    can therefore be socially excessive even without collusion. The only exception
    among commonly used demand functions is the set of constant demand functions. '
