Abstract
The labour employment trends of 2003 Swiss FADN farms between 2004 and 2009 are studied,
differentiating between the use of on- and off-farm family labour, employees, and contracting services
accomplished by and for third parties. By means of a correlation and data envelopment analysis, the
relationships between changes in labour input, farm size, productivity and income are empirically
explored. With the aid of a cluster analysis 7 major strategies to adjust labour input are revealed whereas
slightly over half of the farms in the period under consideration leave labour input at a constant level.
Although some of the clusters differ substantially in terms of growth in both labour productivity and
income, differences in total factor productivity are not significant.
