Measuring Domestic Logistics Costs
This section outlines a number of macro-level methodologies that could be
used to measure various aspects of domestic logistics costs. The emphasis is
on exploiting existing data sources. The first subsection discusses the
treatment of logistics in the national accounts, and provides some
approximate data on the size of the logistics sector relative to GDP in a
number of countries. The second subsection presents data relevant to logistics
from the International Comparison Program, focusing on both the size of the
sector relative to GDP and prices. The third subsection uses firm-level data
from the World Bank’s Enterprise Surveys dataset to analyze productivity in the
logistics sector across a range of countries.
