Purpose – This study aims to examine how embeddedness influences consultants’ information seeking when making decisions within a social network of relationships, and how these social networks evolve throughout the project delivery stages. The study is grounded in social network theory and...

We study a model of collective search by teams. Discoveries beget discoveries and correlated search results are governed by a Brownian path. Search results' variation at any point---the search scope---is jointly controlled. Agents individually choose when to cease search and implement their best...

This paper reviews recent research on the aggregation of heterogeneous time preferences. Main results are illustrated in simple Ramsey models with two or three agents who differ in their discount factors. We employ an intertemporal view on these models and argue that preferences of a decision...

Consider the following principle regarding the performance of collective choice rules. "If a rule selects alternative x in situation 1, and alternative y in situation 2, there must be an alternative z, and some member of society whose appreciation of z relative to x has increased when going from...

1. Problem definition: This paper studies how teams make operational decisions in two canonical settings: standalone Newsvendor inventory decisions (tactical decision-making) and Newsvendor under information sharing (strategic decision-making). 2. Academic / Practical Relevance: Team...

We experimentally investigate the path dependence of voluntary contributions in a public good game with heterogeneous agents who vary in their ability to increase the public good. More specifically, we analyze whether contribution norms observed in a first phase of the experiment under a...

A committee divided into two factions is considering a costly project. Support of both factions is required for the project to be approved. As long as the decision is delayed, the committee can learn which faction benefits from the project. At the equilibrium, one of the factions effectively...

Quantitative scholarship on civil conflict still largely relies upon the ethnic group as the foundation for measures of politically-relevant diversity and, in particular, identity-based political inclusion. However, ethnicity remains notoriously difficult to measure: even cutting-edge analyses...

Does increased partisanship undermine the ability of politically heterogeneous groups to function and cooperate in apolitical settings? On the eve of the 2020 U.S. elections, we conducted an online experiment in which Democrats and Republicans played repeated public goods games, both with and...

Are there collective decision methods which (i) give everyone, including minorities, an equal share of effective power even if voters act strategically, (ii) promote consensus and equality, rather than polarization and inequality, and (iii) do not favour the status quo or rely too much on...
