This paper provides mathematically consistent calculations of the forward, backward, and total linkages in the Brazilian economy in 1975. Our results reveal, among other things, that : 1) high linkages cannot be exclusively associated with modern industrial sectors; 2) none of our linkage measures have any consistent relationship with domestic resource cost, our measure of efficiency; 3) there are some doubts on the proposition that Brazilian economic growth has been linkage-intensive; and 4) there are some important differences between "key" sectors from the standpoint of backward and forward linkages.22 p.
