During the time period (1998 – 2002) when a large part of the data used in this study was collected, the average herd size was about 30 cows. Due to a major structural change that is taking place at the moment, the average herd had grown to 46 cows in 2005 (Statistics Sweden, 2006), a figure that suggests that the farms grow quickly. However, many dairy farms also exit dairy production. Farm production at a Swedish dairy farm is often diversified, where the farms have major beef production and also Drivers and Restraints for Economic and Technical Efficiency in Dairy Farms 19 cash crop production.

Tobit regression was used also in the research project synthesized in this chapter. Simpler alternatives, like the ordinary least square regression, may cause predicted values of efficiency to exceed one, which is not desirable. On a few occasions in this research project, however, logistic regressions were used instead, because that modelled better what was demanded.
