Why do people appear to forgo information by sorting into “echo chambers”? We construct a highly tractable multi-sender, multi-receiver cheap talk game in which players choose with whom to communicate. We show that segregation into small, homogeneous groups can improve everybody’s...

In this explorative study, we adopt a knowledge-centred perspective on clusters and investigate whether clusters' internal structure explains clusters' external (knowledge) collaborative strategies. All in all, the main analytical issue underlying this paper is the following: do internal...

We analyze a model of endogenous two-sided network formation where players are affected by uncertainty in their opponents' decisions. We model this uncertainty using the notion of equilibrium under ambiguity (Eichberger and Kelsey, 2014). Unlike the set of Nash equilibria, the set of equilibria...

I present a novel experimental design to measure lying and mistrust as continuous variables on an individual level. My experiment is a sender-receiver game framed as an investment game. It features two players: firstly, an advisor with complete information (i.e., the sender) who is incentivized...

We study the role of information about the multiplier in a finitely repeated investment game. A high multiplier increases the reputational incentives of a trustee, leading to more repayments. Our perfect Bayesian equilibrium analysis shows that if the trustee is privately informed about the...

Freelancing human experts play an important role in Initial Coin Offerings (ICOs). Expert ratings partially reflect the reciprocal network of ICO members and analysts. Ratings predict ICO success, but highly imperfectly so. Favorably rated ICOs tend to fail when more ratings reciprocate prior...

The question of the determinants of inter-regional knowledge flows has received a growing interest in the recent past. Particularly, the question of the relationship between geography and networks has been debated. Yet, at the inter-regional level, there is no study assessing the effect of...

This paper analyse how previous experience and affiliation influence individual employees but also the current employers. Knowledge can be embodied in several different forms, in individuals, in books, in machines, or in processes. Human capital refers to embodied knowledge in individuals,...

The construction of formal models that deal with space observed a huge increase since the late 1980s. As Fujita et al. (1999) stress, the field of regional economics experienced a revival with the emergence of new analytical tools such as the diffusion of imperfect competition models, networks...

The EU Framework Programme (FP) belongs to the most important instruments promoting transnational collaborative R&D projects in Europe. Its main objective is to initiate cross-border complementarities in order to exploit knowledge resources and to conduct large scale research. Within the EU FPs...
