The importance of cooperative behavior in business environments has been theorized in the field of management. However, measuring cooperation quantitatively is often challenging.

We find that Mongolian entrepreneurs generally achieve much higher cooperation levels and hence higher experimental earnings than Mongolian students. Also, among individual participants, producing and desisting from theft in the lab setting is correlated at the 1% level with real‐world business sales. Our findings align with the view that cooperative impulses or abidance of social norms can be an advantage in business relationships.
