Resumen
Descripción
The cross-sectional approach to the assessment of climate change impacts on
agriculture is a widely used technique. It is based on land prices and supposes a perfect
mobility of agricultural activities following climate evolution. Theory and our empirical
study of the French land market show that land prices do not only reflect the land rent
related to productivity. We argue, that geographical labeling represents a component of
land prices which is space invariant. Thus, present rents related to geographical labeling
cannot be transferred to new regions, as a cross-sectional analysis would suggest.
