The article introduces “hiding behavior” as a concept for understanding why people conceal economic problems and solve them by committing crimes. This concept's theoretical purport, empirical applicability, and relevance for the research area are considered through an analysis of an empirical case. An explanatory model is then developed, focusing on the concrete social relations in which hiding behavior originates and in which it remains embedded. From case studies we see how hiding behavior is situated in social relations characterized by a specific form of uncertainty arising from engulfment and isolation. In these relations money plays a central role, providing a medium for action-coordination essential in the incidence of economic crime. Finally, the explanatory power of the proposed conceptual model is discussed, with several possible refinements suggested for it.
