USA: Categorial Economic Policy Uncertainty Index, Trade Policy (NSA)

The Categorical Economic Policy Uncertainty (EPU) Indexes include a range of sub-indexes based solely on news data.

Each sub-index requires economic, uncertainty, and policy terms as well as a set of categorical policy terms. For instance, articles that fulfil to requirements to be coded as EPU and also contain the term \'import tariffs\' would be included in the trade policy uncertainty sub-index.Each categorical series is multiplicatively normalized to have a mean of 100 from 1985-2010.A full list of terms (Categorical Term List) can be found at: https://www.policyuncertainty.com/categorical_terms.html.
