Abstract: The Global Talent Competitiveness Index (GTCI) attempts to summarise complex and versatile concepts related to human capital and talent competitiveness at the national scale worldwide. The JRC analysis suggests that the conceptualised multi-level structure of the GTCI 2013 is statistically coherent and balanced (i.e., not dominated by any pillar or sub-pillar; all indicators contribute to the variation of the respective Input/Output sub-indices and to the overall GTCI). The reliability of the GTCI, as measured by the Cronbach-alpha value, is very high at 0.94 (well above the recommended 0.7 threshold for a reliable aggregate). Furthermore, the analysis has offered statistical justification for the equal weights and the use of arithmetic averaging at the various levels of aggregation. It has also shown that the GTCI is “statistically” more reliable in the current form, namely built as the average of the six pillars, instead of the average of the Input and Output sub-indices. The GTCI and sub-index country ranks are robust to methodological assumptions related to the estimation of missing data, weighting, and aggregation formula (less than three position shifts on average for 94 out of 103 countries). Consequently, inferences can be drawn for most countries in the GTCI, while some caution may be needed for a few countries. Note that perfect robustness would have been undesirable as this would have implied that the GTCI components are perfectly correlated and hence redundant, which is not the case for the GTCI 2013. In fact, one way in which the GTCI helps to highlight other components of human capital and talent competitiveness is by pinpointing the differences in rankings that emerge from a comparison between the GTCI and each of the six pillars: for more than 32% (up to 58%) of the countries, the GTCI ranking and any of the six pillar rankings differ by ten positions or more.
