A structural gravity model is used to estimate barriers to services trade across many sectors, countries
and time. Since the disaggregated output data needed to flexibly infer border barriers are often missing
for services, we derive a novel methodology for projecting output data. The empirical implementation
sheds light on the role of institutions, geography, size and digital infrastructure as determinants of
border barriers. We find that border barriers have generally fallen over time but there are differences
across sectors and countries. Notably, border effects for the smallest economies have remained stable,
giving rise to a divergent pattern across countries
