Many sources of economic data cover only a limited set of states at any given point in time. Data are often systematically missing for some states over certain time periods. In the context of conflict studies, economic data are frequently unavailable for states involved in conflicts, undermining the ability to draw inferences of linkages between economic and political interactions. For example, simply using available data in a study of trade and conflict and disregarding observations with missing data on economic variables excludes key conflicts such as the Berlin crisis, the Korean War, the Cuban Missile Crisis, and the Gulf War from the sample. A set of procedures are presented to create additional estimates to remedy some of the coverage problems for data on gross domestic product, population, and bilateral trade flows.
