Robust measurement of national technological progress

We propose a measure of technological progress based on the information embedded in standard input-output tables. A connection is established between the quantities necessary as inputs, the associated output and auxiliary prices. It is argued that the wage-profit frontiers and the associated production prices together provide a robust basis for measuring technological progress and productivities. The computation of the wage-profit frontiers is a non-trivial exercise because of high combinatorial complexity. An algorithm that renders this computation feasible is presented. We analyze technological progress and productivities among 30 countries between 1995-2011 using the latest multi-regional input-output data.
