Integrating national accounting and macroeconomic approaches to estimate the underground, informal, and illegal economy in European countries

Abstract

This article proposes a hybrid national accounts (NA)-macroeconometric approach to fill the gap between the demand for reliable and internationally comparable estimates and the sparse availability of official statistics based on the NA approach. The proposed method combines data from Eurostat’s Tabular approach for the exhaustiveness of NA with estimates based on theoretical hypotheses on the drivers of non-observed production. We estimate underground, informal, and illegal economies for 22 European countries over the period 2000–2020.
