This paper investigates the effect of migration on farm technical efficiency
drawing on a large and representative sample of agricultural households in
Kosovo. A two-stage estimation procedure is applied: a frontier technique to
estimate the effect of migration on farm efficiency, followed by a propensity
score based matching approach to robustly estimate the sample average effect
on efficiency for different levels of migration intensity. Migration is found to
have an efficiency decreasing effect which is amplified for better educated
workers. The observed negative effect of migration on efficiency is evident
even at low levels of migration intensity.
