To select criteria to assess the effects of national government
involvement, we looked at the objectives behind this involvement.
Urban-economic development was the main motive behind both
generations of key projects and the main reason for the national
government to become involved in the projects. The benefits of this
development would accrue to public as well as private parties by
such means as private investment, employment growth (particularly
in the service sectors) and an increase in the demand for office
space and housing, and lead to higher real estate prices (cf. Brounen
& Jennen, 2008: 400; De Wit & Van Dijk, 2003: 39).
