The article looks at how people bargain in groups. When everyone has to agree, everyone spends the same amount of effort. But when only some need to agree, patient people put in more effort. Surprisingly, patient people might end up with less money. If groups are different, it can cost more to reach an agreement. Big groups do better in bargaining. Groups that need more agreement tend to grow. And sometimes, people agree too quickly because they don't want to spend more money.
