Resumen
Descripción
This paper investigates how the
sector-specific source or the changing sectoral composition
of labor productivity has contributed to aggregate beta
convergence, using a newly constructed eight-sector
database. The main findings are twofold. First, both within
and sectoral reallocation have become important drivers of
aggregate convergence in labor productivity. Second,
agricultural productivity growth has been a significant
contributor to aggregate convergence, whereas catch-up in
other sectors has only contributed a small amount to
convergence. The strong growth of the agriculture sector has
been the most important driver of aggregate productivity
convergence even though agricultural productivity itself in
low-income countries is weakly converging to that in
advanced economies.
