This paper provides the details of the construction of new quarterly measures of the real GDPs of the 36 US trading partners that are taken into consideration by the Federal Reserve in its "broad exchange rate" indexes. These new measures have some important advantages. First, they allow the construction of various income aggregates and sub-aggregates, which makes it possible, for example, to match the Federal Reserve's "broad," "major-currency," and "other important" trading partner effective exchange rates and, more broadly, to discuss the geographical and geopolitical determinants of US trade. Second, they allow the construction of variants of the two different types of measures that are utilized in the literature, namely direct and export-share-weighted sums of trading-partner real GDPs. Finally, given that our new measures of GDP for these countries can be directly compared to each other, they can be of interest for other researchers who need a consistent dataset on a quarterly basis.
