How can governments reduce the prevalence of cross-border tax fraud? This paper argues that the use of digital technologies offers an opportunity to reduce fraud and increase government revenue. Using data on intra-EU and world trade transactions, we present evidence that (i) cross-border trade tax fraud is non-trivial and prevalent in many countries; (ii) such fraud can be alleviated by the use of digital technologies at the border; and (iii) potential revenue gains of digitalization from reducing trade fraud could be substantial. Halving the distance to the digitalization frontier could raise revenues by over 1.5 percent of GDP in low-income developing countries.

This paper analyzes saving patterns and determinants in Latin America and the Caribbean (LAC), including key policy variables and regimes. The review of previous empirical studies on LAC saving reveals contradictions and omissions. This paper presents empirical results of an extensive search of determinants of private and public saving rates, adding previously neglected variables (including different measures of key external prices and macroeconomic policy regimes), in linear form and in interactions with other saving determinants. It analyzes statistical differences in saving determinants between LAC and the rest of the world in a nested econometric framework, and discusses differences across three country subgroups within LAC. The results highlight commonalities and differences in saving behavior between LAC and other world regions, as well as within LAC, identifying the role of key policy variables and regimes.
