Through their writing, people often reflect their values. Since the 1970s, academic economists have gradually changed their third-person pronoun choices, from using the masculine form to incorporating feminine and plural forms. We document this transition empirically, and examine the role of...

The persistence literature in economics and related disciplines connects recent outcomes to events long ago. This influential literature marks a promising development but has drawn criticism. We discuss two prominent examples that ground the rise of the Nazi Party in distant historical roots....

A stable government is by definition not dominated by any other government. However, it may happen that all governments are dominated. In graph-theoretic terms this means that the dominance graph does not possess a source. In this paper we are able to deal with this case by a clever combination...

A well-known model in sociology and marketing is that of opinion leadership. Opinion leaders are actors who are able to affect the behavior of their followers. Hence, opinion leaders have some power over their followers, and they can exercise this power by influencing their followers choice of...

In the absence of well-established factor markets, the role of indigenous institutions and social networks can be substantial for mobilizing factors for agricultural production. We investigate the role of an indigenous social network in Ethiopia, the iddir, in facilitating factor market...

One of the most famous ranking methods for digraphs is the ranking by Copeland score. The Copeland score of a node in a digraph is the difference between its outdegree (i.e. its number of outgoing arcs) and its indegree (i.e. its number of ingoing arcs). In the ranking by Copeland score, a node...

We consider a connection networks model. Every agent has a demand in the form of pairs of locations she wants connected, and a willingness to pay for connectivity. A planner aims at implementing a welfare maximizing network and allocating the resulting cost, but information is asymmetric: agents...

We consider a generalization of the Minimum Cost Spanning Tree (MCST) model dubbed the Minimum Cost Connection Network (MCCN) model, where network users have connection demands in the form of a pair of target nodes they want connected directly, or indirectly. Given a network which satisfies all...

The purpose of this paper is to explore the problem of power distribution within networks of relationships between companies and consumers (business-to-consumer (B2C) networks) and to examine the ways in which value is created and captured in such structures. To this end, we applied the network...

Online platforms facilitate the formation of micro-communities on the Internet by enabling exchange between locally dispersed individuals. Since all interactions are mediated through the online platform, user representation plays a critical role for such communities. Grounded in Social Exchange...
