Factors of Variation Why do backward linkages differ among countries and over time? There are variations in Product mix Relative prices of construction inputs Construction technologies Although there is not a sufficient amount of data to standardize these factors of variation, there are other ways to assess the strength and nature of construction backward linkages… Examine backward and forward linkage measures for aggregate construction sector in a number of countries and over time!
