The shadow (underground) economy plays a major role in many countries. People evade taxes and regulations by working in the shadow economy or by employing people illegally. On the one hand, this unregulated economic activity can result in reduced tax revenue and public goods and services, lower...

Recently, there has been growing recognition that some formal employees receive from their formal employers two wages, namely an official declared wage plus an additional undeclared (envelope) wage, which reduces the tax and social contributions paid to the authorities. The aim of this paper is...

In recent years, it has been increasingly recognised that governments seeking to tackle undeclared work effectively should adopt a holistic approach. This seeks to coordinate strategy across the fields of labour, tax and social security law, and to use the full range of policy measures...

The aim of this paper is to evaluate two contrasting ways of explaining and tackling undeclared work. The rational economic actor approach theorizes undeclared work as arising when the benefits of undertaking undeclared work outweigh the costs, and the policy focus is upon deterring undeclared...

To tackle participation in unregistered employment, the conventional policy approach has been to deter such work by increasing the penalties and risk of detection. Recently, an alternative preventative approach has emerged that tackles participation in unregistered employment by improving...

In recent years, participants in the informal economy have started to be viewed less as rational economic actors who engage in the informal economy when the pay-off is greater than the expected cost of being caught and punished, and more as social actors who engage when their tax morale (i.e.,...

This paper provides an evidence-based evaluation of the competing ways of explaining and tackling the informal economy. Conventionally, participants have been viewed as rational economic actors who engage in the informal economy when the benefits outweigh the costs, and thus participation is...

We review existing estimates of the size of the Spanish underground economy, apply the Ahumada et al. (2007, RIW) correction procedure to some of them and calculate the size of the underground economy in Spain for the period 1960 through 2009 by using the modified-cash-deposits-ratio (MCDR)...

We further refine the Modified-Cash-Deposits-Ratio (MCDR) approach, developed by Pickhardt and Sardà (2011, 2012) with a view to analyze size and causes of the cash using section of the underground economy. Among other things, we address the issue of cash hoarding. Findings include that the...
