Leandro Prados de la Escosura publicó Spain’s HistoricalNational Accounts: Expenditure and Output, 1850-2015, una actualización de sus estadísticas históricas de cuentas nacionales españolas. Leemos en el abstract "This
essay offers a new set of historical GDP estimates from the demand and supply
sides that revises and expands those in Prados de la Escosura (2003) and
provides the basis to investigate Spain’s long run economic growth. It presents
a reconstruction of production and expenditure series for the century prior to
the introduction of modern national accounts. Then, it splices available
national accounts sets over the period 1958-2015 through interpolation, as an
alternative to conventional retropolation. The resulting national accounts
series are linked to the ‘pre-statistical era’ estimates providing yearly
series for GDP and its components since 1850. On the basis of new population
estimates, GDP per head is derived. Trends in GDP per head are, then, drawn
and, using new employment estimates, decomposed into labour productivity and
the amount of work per person, and placed into international perspective"
