Dual sourcing with price discovery
Alcalde, José; Dahm, Matthias - 2016
Reverse auctions are considered a fast and inexpensive price discovery tool to award procurement contracts and it is … often desirable to award contracts to more than one supplier. We propose a new procurement procedure that is based on a … enough, the procedure not only allows taking advantage of dual sourcing but also generates lower procurement expenditures …

Risk-taking in social settings : group and peer effects
Bougheas, Spiros P.; Nieboer, Jeroen; Sefton, Martin - 2013 - Revised version of 2013-01, This version: June 6, 2013
We investigate experimentally the effect of consultation (unincentivized advice) on choices under risk in an incentivized investment task. We compare consultation to two benchmark treatments: one with isolated individual choices, and a second with group choice after communication. Our benchmark...

Contagion of pro- and anti-social behavior among peers and the role of social proximity
Dimant, Eugen - 2018
This paper uses a novel experimental design to study the contagion of pro- and antisocial behavior and the role of social proximity among peers. Across systematic variations thereof, we find that anti-social behavior is generally more contagious than pro-social behavior. Surprisingly, we also...

On peer effects : contagion of pro- and anti-social behavior and the role of social cohesion
Dimant, Eugen - 2017 - This Version: April 2017
Little is known about the underlying mechanisms of behavioral contagion, in particular with respect to differences in contagion of pro- versus anti-social behavior. Our principal contribution is the use of a novel experimental approach that enables us to analyze the contagion of behavior under...

Heterogeneity and cooperation in privileged groups : the role of capability and valuation on public goods provision
Kolle, Felix - 2012
We experimentally investigate cooperation in privileged groups which according to Olson (1965) are groups in which at least one member has an incentive to supply a positive amount of the public good. More specifically, we analyze group member heterogeneity with respect to two dimensions:...

Cooperation in small groups : the effect of group size
Nosenzo, Daniele; Quercia, Simone; Sefton, Martin - 2013 - Revised version of 2012-17, This version: 29 July 2013
We study the effect of group size on cooperation in voluntary contribution mechanism games. As in previous experiments, we study four- and eight-person groups in high and low marginal per capita return (MPCR) conditions. We find a positive effect of group size in the low MPCR condition, as in...
