(Inter)regional Input-Output Table Estimation from Surveys to Spatial Econometrics

Abstract

Researchers and practitioners who consider economic regional (sub-national)
policy questions often face the problem of regional input-output (I–O) table
unavailability. The literature offers a number of approaches to approximate such
tables. In this paper, a survey of the leading state-of-the-art methods in the field
is presented, and their pros and cons are discussed. I take into account both
single-region approaches, such as the location quotient (LQ) family, as well as
interregional input–output (IRIO) methods, especially their class referred to as
gravity-RAS. I pay particular attention to recent developments in using spatial
econometric methods (Spatial IRIO). The discussion is illustrated with simple
numerical examples and selected empirical results.
