attacks on New York and Washington on September 11, 2001 (henceforth 9/11), the (economic) analysis of terrorism has gained in importance in (economic) research. Some contributions have focused on the causes of terrorism, asking, e.g., whether terrorism is rooted in poor political and economic conditions (i.e., in repression and poverty). Others have centered on the consequences of terrorism. For instance, (global) terrorism may damage economic growth and globalization, e.g., by reducing trade flows and investment flows. The interaction of terrorism and counter-terrorism has also been the center of some academic interest, given that the fight against terrorism also has noticeable economic consequences of its own accord, e.g., by affecting the ease of travel and trade and by diverting public investment to internal security. This survey provides an in-depth analysis of existing research on the economic analysis of terrorism and
