Do the Baltics form an integrated economic area, or are they just neighbours? The recently issued ECFIN paper "The Baltics: three countries, one economy?" takes a quantitative look at the question.
There seems to be an integrated Baltic economy, i.e. an area driven for a sizeable part by common factors and economic links. Yet, there are also asymmetries, with Estonia being the most exposed to international developments, Latvia being less influenced by regional spillovers and Lithuania being a much less influential driver.
Note: EA-16 is EA-19 excluding the Baltic countries. EU-25 is EU-28 excluding the Baltic countries.
