Keeping zero tariffs is good economics, but the EU's political interest matters too

Tariffs are a key element in any trade deal negotiated between the EU and the UK. Ozlem Taytas Ozturk (LSE) explains why and writes that while a zero tariff arrangement is in the economic interests of all the business sectors involved, the final deal may be swayed by politics. The EU may impose some tariffs in order to discourage non-EU countries from seeking a better deal with the bloc, and discourage restless members from leaving.
