The complexities of the relationship between a country's level of construction activity and its stage of economic development are considerable. Studies over the last three decades, based on macroeconomic analysis, have attempted to model the relationship but have usually been hampered by problems of data quality and availability. Nevertheless, paradigms have emerged (usually based on Keynesian philosophy), which are concerned with the dynamics of construction activity as an agent in the promotion of economic growth in economies at different stages of development. One such is the 'Bon curve'. An examination of the data issues of attempting to assess the validity of the proposition is made and then the role of the construction sector in highly developed economies is considered.
