The STPD offers comparable information on services trade policies for 68 economies in 23 subsectorsacross five broad areas ― financial services, telecommunications, distribution, transportation andprofessional services, respectively. The STPD features several improvements. First, data arecollected according to a newly developed policy classification, consistent with both the earlier WorldBank database and the current OECD database, enabling for the first time a comparison of servicespolicies over a significant period and across a large cross-section of industrial and developingeconomies. Second, the database contains information not just on core trade policies but also onother increasingly relevant aspects, such as licensing conditions and data restrictions. Third, policyrestrictiveness is quantified following a more systematic approach that aggregates the informationwithin a single consistent and transparent framework. Building on these innovations will make itpossible to identify global patterns of services trade policies as well as secular trends in policymakingover the past decade.
