purpose, we will walk through the Tunisia trade dashboard, and provide links between the different dimensions of its analysis and the WITS GVC Module every step of the way.

The first tab of country‐level dashboards is obtained from the output of the country analysis query, displaying information on final and intermediate goods’ GVC gross exports and imports by the selected country to/from the world in each of the selected GVC categories (as aggregated by the user), both in dollar values and as a percentage share of the country’s total exports (imports), total manufacturing exports (imports) and GDP in current USD, as well as dollar values of those aggregates, over the specified period of analysis.<sup>25</sup> These data can be presented in table format and line graphs, displaying the evolution of export and import flows in each of the GVC categories selected in the country analysis query, over time. Whenever one export flow is much larger than the rest, it is advisable to present a second set of graphs excluding such flow, in order to render visible any trends that may be otherwise unnoticeable in the remaining GVC export flows In the case of the Tunisia dashboard, exports of final goods and imports of intermediate goods in the Apparel & Footwear GVC category are substantially larger than in any other categories, and are consequently excluded from the second set of diagrams to enhance readability.

The second tab of country‐level dashboards compares exports and imports of final and intermediate goods belonging to each of the selected GVC categories in the country of interest, to those in each of the peer countries included in the customizable comparators’ group. In the case of Tunisia, the default pre‐ selected set of comparator economies includes Bulgaria, Colombia, Costa Rica, Dominican Republic, El Salvador, Jordan, Morocco, Thailand and Turkey. The output of the country analysis query displays GVCs export and import data for all these countries and the country of interest (in our example, Tunisia), both in dollar values and as a share of total exports (imports), in the initial and final years of the selected period, as well as the compound annual growth rate (CAGR) between these two points in time.<sup>26</sup> This provides a benchmark for the analysis of the country’s GVC export performance and import dependence in each of the products and categories, and introduces a dynamic criterion in this assessment by looking not only at GVC exports and imports in each category in levels, but also evaluating their growth over time.

The third tab of the dashboard exploits information from the products of interest query, whose output yields a list of the top individual products at the six‐digit level of aggregation within each of the selected GVC categories, ranked on either export or import value (or both) on a year of choice within the analysis period selected in the query. The actual number of products to be displayed is customizable, with the default option set in twenty products. The user also has flexibility to choose the initial and final years to be used for the calculation of market shares and compound annual growth rates. For the resulting subset of products and for both the country of interest and all of its comparators, the output of the query includes total exports and imports in dollar values, global market shares in percentages, and world exports and imports in dollar values, in all cases both in the selected initial and final years, as well as the compound annual growth rate of country’s imports and exports between the two. All these data allow to quickly grasp a bunch of information on each of these products: their relative importance in term of the dollar value of their exports and/or imports and whether there is two‐way trade; how fast they have been growing or, on the contrary, if they are on the decline; and whether such trend has been consistent or otherwise there have been trend changes or any atypical export values in any of the years within the considered time span. In the case of Tunisia, the existence of both imports and exports within these

> 25 The longest possible period of analysis at the time of writing is 28 years spanning 1988‐2014, when choosing H0 nomenclature (HS 1988/92).

> 26 Whenever any of the selected peer countries does not have available data in one or both of the selected years, data corresponding to a proximate year are presented instead, noting this in a footnote.
