Resumen
Descripción
Rural access is among the most important
infrastructure constraints in rural Africa. Using the
results from comprehensive household surveys and other data
from Ethiopia, the paper recasts light on the heterogeneous
impacts of road accessibility on agriculture and
nonagricultural growth. It is found that crop production is
increased by major and feeder road improvements. Significant
synergy is also found. When investigating further into this
effect, there are two impacts: farmers' access to the
input market, especially fertilizer, was improved mainly by
major corridor improvement. And output market access was
improved by feeder road improvement. In addition, the
household's nonagricultural income is somehow increased
by improved road connectivity. There must be secondary
effects. The transport demand function estimated with
additional data indicates that as the road network improves,
people's mobility increases. Furthermore, local
business employment is found to increase with road
improvements. To meet the increasing demand for mobility,
efficiency and frequency of transport services are important.
