Do Peers Affect Student Achievement? Evidence from Canada Using Group Size Variation
We provide the first empirical application of a new approach proposed by Lee (2007) to estimate peer effects in a linear-in-means model. This approach allows to control for group-level unobservablesExpand

Imprints of dark energy on cosmic structure formation: II) Non-Universality of the halo mass function
The universality of the halo mass function is investigated in the context of dark energy cosmologies. This widely used approximation assumes that the mass function can be expressed as a function ofExpand

  • 1 April 2016
I present a model of conformism in social networks that incorporates both peer effects and self-selection. I find that equilibrium behaviors are linked through the Laplacian matrix of the equilibriumExpand

Imprints of dark energy on cosmic structure formation – I. Realistic quintessence models and the non‐linear matter power spectrum
Quintessence has been proposed to account for dark energy (DE) in the Universe. This component causes a typical modification of the background cosmic expansion, which, in addition to its clusteringExpand

Providing global public goods under uncertainty
We study how uncertainty and risk aversion affect international agreements to supply global public goods. We consider a benchmark model with homogeneous countries and linear payoffs. When countriesExpand

Effective permeability tensor and double resonance of interacting bistable ferromagnetic nanowires
We present a model for the effective permeability tensor of nonsaturated arrays of axially magnetized bistable ferromagnetic wires based on a Maxwell-Garnett formalism generalized to include the caseExpand

Introducing the Dark Energy Universe Simulation Series (DEUSS)
In this "Invisible Universe" proceedings, we introduce the Dark Energy Universe Simulation Series (DEUSS) which aim at investigating the imprints of realistic dark energy models on cosmic structureExpand

My Friend Far Far Away: Asymptotic Properties of Pairwise Stable Networks
We explore the asymptotic properties of pairwise stables networks (Jackson and Wolinsky, 1996). Speci fically, we want to recover a set of parameters from the individuals' utility functions using theExpand

Giant magneto-optical Faraday effect in GaP epilayers containing MnP magnetic nanoclusters
We report a giant magneto-optical (MO) effect in a GaP(011) epilayer with embedded MnP nanoclusters (GaP:MnP) grown on a GaP(011) substrate using metal-organic vapor phase epitaxy. The MO effectExpand
