Attanasio Selection-Bias Decomposition Framework
"Therefore, if the estimated treatment effect on quality conditional, of course, on submission is positive and significant, this is in effect an unambiguous indication of a positive unconditional effect as well."
Face-to-Face vs. Virtual Peer Interaction Scalability Trade-Off
"For the UgS we find that whereas the treatment effect on submission is positive and very significant for the face-to-face treatment, the positive effect arising under virtual-within interaction is not statistically significant."
First-Order Stochastic Dominance (FOSD) Communication Polarization
"Messages are quite polarized in either the business or sentiment dimension... showing an inverse dependence in the (strong) FOSD sense between the respective business-based and sentiment-based distributions."
Incentivized Token Peer-Reward Mechanism
"Every two weeks... individuals were provided with 10 tokens. They were advised to hand these tokens to those peers whom they found most helpful... the tokens given by the 50 highest-ranked entrepreneurs... acted as lottery tickets for one of the 30 (attractive) rewards."
Asymmetric Market-Scale Effect on Peer Network Diversity
"In the set of small countries, where only virtual-across interaction is possible, there are positive and significant peer effects on both extensive and intensive quality but not on submission... Instead, when entrepreneurs of large countries are exposed to virtual-across interaction, no significant peer effects arise in any of the three outcomes."
Negative Peer-Composition Effect
"However, the average baseline quality of group peers have a negative composition effect on intensive quality. In fact, a similarly negative composition effect is also induced by peers' average experience level."
Post-Indexed Communication Lag Parameterization
"For a value of $\tau = 80$... the estimated peer coefficient reaches in every case a value very close to the coefficient estimated for $\tau = \infty$."
Second-Order Peer Instrumentation (G²X Identification)
"The approach we pursue here to tackle the reflection problem follows Bramoullé et al. (2009) and De Giorgi et al. (2010)... It relies on using the variables in G²X (the total influence weights associated to the peers lying two links away) as respective instruments for Gy."
Semantically Weighted Peer Networks and Multidimensional Communication Balance
"Tables 20 and 21 show that, either through business-weighted or sentiment-weighted links alike, peers can exert significant influence... even though business-oriented messages are often weak in sentiment content and vice versa, individuals tend to use a quite balanced set of the two types in the overall communication they establish with any given peer."
Stability Selection via Bootstrapped Regularized Logistic Regression
"We fit from 200 to 1,000 independent logistic-regression models on random subsets of the data... The regressors that have a score larger than 0.5 are declared to be informative."
Two-Stage Expert and Senior Investor Evaluation Mechanism
"A total of 93 proposals actually moved into a concrete follow-up by the investor. Up to 30 of them had been funded or were still followed up as of November 2018."
