This paper reviews reassesses the methodology and principal findings of the “Rose effect”, i.e. the trade effects of currency union, looking at both EMU and non-EMU currency unions. The consensus estimate suggests that the euro has already boosted intra-euro area trade by five to ten percent. The paper discusses a gamut of models that might explain the Rose effect in Europe and suggests a series of empirical test that could help identify the economic mechanisms involved.
