Tax Evasion and the Shadow Economy

Tax Evasion and the Shadow Economy

Edited by Michael Pickhardt and Aloys Prinz

Leading scholars examine recent evidence from theoretical and empirical research on tax compliance and tax evasion, and provide an in-depth analysis of underlying methods. Strategies to fight tax evasion are evaluated and the motivations behind it are explored, as are the impact and size of the shadow economy in Europe. As well as promoting a better understanding of the issues, this book intends to stimulate further debate and, in so doing, broaden the exchange of ideas and concepts.

The OECD has designed a framework in order to classify such activities as belonging to the so-called non-observed economy (NOE). There are (too) many words to encapsulate activities related to NOE within an economy e.g. ‘black, concealed, hidden, informal, non-observed, shadow, subterranean, unrecorded’, etc. Among scholars, the aforementioned terms are loosely used as mere synonyms, whereas different terms purport to capture different activities according to their scope. The field research has been expanding since the late 1970s. Thus a brief review of the landmarks of its history and major steps to achieve a tractable taxonomy is required (see Box 5.1). Beyond taxonomy, the NOE is a controversial issue on several grounds: definition and scope, and estimates as regards the magnitude as well as the trend of the NOE, upon which scholars disagree. How should the NOE be accounted for? Has the NOE been expanding until the late 1990s and declining since, or does it remain fairly stable? Does it represent a large or small share of GDP? Section 5.2 is devoted to definition and scope: the NOE is designed as a set of eight types liable to taxes that are encapsulated within five categories: the illegal economy or underground economy, as well as the informal economy, for statistical and economic reasons,...
