Financial market speculation leads to individual gain at the expense of society.
The article discusses how people in financial markets make decisions based on uncertainty and the actions of others. Agents try to predict what others will do to avoid losses or make money. This can lead to a lack of collective perspective and coordination. The study suggests that without specific tools, understanding of common reality, and agreement on actions, individual decisions may not lead to overall satisfaction or social welfare. Rules are seen as guidelines to help coordinate collective actions, rather than constraints.
