Domestic Trade in Services in Regional Input-Output Models

Lack of statistical data on interregional trade in services often leads regional input-output (I-O) models to rely on assumptions about the degree to which services are imported from other regions. One advantage of using an I-O model is that it provides the flexibility to tailor the basic model to provide more accurate estimates. This paper reviews the literature on tradability of services for insights that may improve the design of individual economic impact studies based on regional I-O models.
