Abstract
The paper sought to estimate technical efficiency in Ghana’s agricultural sector and more importantly, investigate
the factors that influence the estimated technical efficiencies.
Using data from 1976-2007, the results showed a
decreasing returns to scale in Ghana’s agriculture.
Land is negatively inelastic showing over use of the factor.
Technology variables, fertiliser and tractor and combines are positively related to output.
Whilst fertiliser is elastic,
tractor and combines is inelastic.
The level of inefficiency is 21% with decreasing returns to scale.
The SFA
specification is the appropriate m
