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...

Home bias is a perennial feature of international capital markets. We review various explanations of this puzzling phenomenon highlighting recent developments in macroeconomic modelling that incorporate international portfolio choices in standard two-country general equilibrium models. We refer...
