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

The Categorical Economic Policy Uncertainty (EPU) Indexes include a range of sub-indexes based solely on news data. These are derived using results from the Access World News database of over 2,000 US newspapers. 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 \'taxation\' would be included in the Taxes 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.
