text: "We study how competition between physicians affects the provision of medical
care. In\r\nour theoretical model, physicians are faced with a heterogeneous patient
population, in which patients\r\nsystematically vary with regard to both their
responsiveness to the provided quality of care and their\r\nstate of health. We
test the behavioral predictions derived from this model in a controlled laboratory\r\nexperiment.
In line with the model, we observe that competition significantly improves patient
benefits\r\nas long as patients are able to respond to the quality provided. For
those patients, who are not able\r\nto choose a physician, competition even decreases
the patient benefit compared to a situation without\r\ncompetition. This decrease
is in contrast to our theoretical prediction implying no change in benefits for\r\npassive
patients. Deviations from patient-optimal treatment are highest for passive patients
in need of\r\na low quantity of medical services. With repetition, both, the positive
effects of competition for active\r\npatients as well as the negative effects
of competition for passive patients become more pronounced. Our\r\nresults imply
that competition can not only improve but also worsen patient outcome and that
patients’\r\nresponsiveness to quality is decisive."

text: We consider a model where for-profit providers compete in quality in a price-regulated
market that has been opened to competition, and where the incumbent is located
at the center of the market, facing high costs of relocation. The model is relevant
in markets such as public health care, education and schooling, or postal services.
We find that, when the regulated price is low or intermediate, the entrant strategically
locates towards the corner of the market to keep the incumbent at the low monopoly
quality level. For a high price, the entrant locates at the corner of the market
and both providers implement higher quality compared to a monopoly. In any case,
the entrant implements higher quality than the incumbent provider. Social welfare
is always higher in a duopoly if the cost of quality is low. For higher cost levels
welfare is non-monotonic in the price and it can be optimal to the regulator not
to use its entire budget. Therefore, the welfare effect of entry depends on the
price and the size of the entry cost, and the regulator should condition the decision
to allow entry on an assessment of the entry cost.

text: We study the effects of product differentiation on the bundling incentives
of a two-product retailer. Two monopolistic manufacturers each produce a differentiated
good. One sells it to both retailers, while the other only supplies a single retailer.
Retailers compete in prices. Retail bundling is profitable when the goods are
close substitutes. Only then is competition so intense that the retailer uses
bundling to relax competition both within and across product markets, despite
an aggravation of the double marginalization problem. Our asymmetric market structure
arises endogenously for the case of close substitutes. In this case, bundling
reduces social welfare.

text: Many countries have opened their health care markets to private for-profit
providers, aiming to promote quality and choice for patients. The prices are regulated
and providers compete in location and quality. We show that whereas opening a
public hospital market typically raises quality, the private provider strategically
locates towards the corner of the market to avoid costly quality competition.
Social welfare depends on the size of the regulator's budget and on the altruism
of the public provider. If the budget is large, high quality results and welfare
is highest in a duopoly whenever entry is optimal. If the budget is small, quality
levels in a duopoly mirror the quality level in a monopoly. It can be optimal
for the regulator not to use the full budget.

text: This paper examines the evolutionary stability of behaviour in contests where
players’ participation can be stochastic. We find, for exogenously given participation
probabilities, players exert more effort under the concept of a finite-population
evolutionarily stable strategy (FPESS) than under Nash equilibrium (NE). We show
that there is ex-ante overdissipation under FPESS for sufficiently large participation
probabilities, if, and only if, the impact function is convex. With costly endogenous
entry, players enter the contest with a higher probability and exert more effort
under FPESS than under NE. Importantly, under endogenous entry, overdissipation
can occur for all (Tullock) contest success functions, in particular those with
concave impact functions.

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. '
