We present eight existing projection methods and test their relative performance in estimating Supply and Use tables (SUTs) of the Netherlands and Spain. Some of the methods presented have received little attention in the literature, and some have been slightly revised to better deal with...

We formulate the problems of finding a "key sector" and a "key group" of sectors in the economy by the hypothetical extraction method (HEM), and derive their analytic solutions that are termed industries' "factor worths". It is shown that the key group of <formula format="inline"><simplemath>"k" ≥ 2</simplemath></formula> sectors is, in...
