In a novel real-effort setting, we experimentally study the effects of different communication media on creative performance in a collaborative tasks. We find that creative performance significantly decreases when group members communicate via chat instead of face-to-face. However, we find no...

This paper analyses the effect of information disseminated by the Internet on voting behavior. We address endogeneity in Internet availability by exploiting regional and technological peculiarities of the preexisting voice telephony network that hinder the roll-out of fixed-line broadband...

How do the social media affect the success of charitable promotional campaigns? We use individual-level longitudinal data and experimental data from a social-media application that facilitates donations while broadcasting donors' activities to their contacts. We find that broadcasting is...

Trust and trustworthiness are important components of social capital and much attention has been devoted to their correct evaluation. In this paper, we argue that individuals' trust and trustworthiness are strongly dependent on the level of trust and trustworthiness of the social group in which...

We survey the literature on social networks by putting together the economics, sociological and physics/applied mathematics approaches, showing their similarities and differences. We expose, in particular, the two main ways of modeling network formation. While the physics/applied mathematics...

We develop a model where, in the first stage, minority individuals have to decide whether or not they want to assimilate to the majority culture while, in the second stage, all individuals (both from the majority and the minority group) embedded in a network have to decide how much effort they...

We address the question of whether media influences occupational choices. To theoretically examine media effects, we construct a dynamic Bayesian occupational choice model with sequential decisions under ambiguity due to imperfect information. We show that sufficiently intensive positive media...

Can media coverage of shooters encourage future mass shootings? We explore the link between the day-to-day prime time television news coverage of shootings on ABC World News Tonight and subsequent mass shootings in the US from January 1, 2013 to June 23, 2016. To circumvent latent endogeneity...

We employ several different approaches to estimate the political position of Australian media outlets, relative to federal parliamentarians. First, we use parliamentary mentions to code over 100 public intellectuals on a left-right scale. We then estimate slant by using the number of mentions...
