The latest empirical results of the size of the shadow economy in 18 OECD countries are presented, using the currency demand approach to calculate the shadow economy over time. The results indicate a strong increase in the size of the shadow economy, over the period 1960 to 1998 and for 15 of...

The main focus of this paper lies on the "driving forces" of the development and size of the shadow economy in 39 highly developed OECD countries. The most influential factors on the shadow economy are tax policies and state regulation, which, if rising, increase the shadow economy, though...

In a simple cash-credit model, I study the effects of the combination of costly tax collection and tax evasion on fiscal and monetary policy for optimal resource allocation. Allowing the informal sector to use cash more intensively than the formal sector, I compute the optimal interest and tax...

This paper develops a competition theory framework that evaluates an important aspect of the OECD's Harmful Tax Practices Initiative against tax havens. We show that the sequential nature of the process is harmful and more costly than a "big bang" multilateral agreement. The sequentiality may...

For the first time we develop a time series of tax evasion (in % of official GDP) for 38 OECD countries over the period 1999 to 2010 based on MIMIC model estimations of the shadow economy. Considering indirect taxation and self-employment as the driving forces of tax evasion, we observe a...

Tax avoidance by major multinational enterprises (MNEs) has been extremely topical after the great financial crisis of 2008. As a result, the Organisation for Economic Cooperation and Development (OECD) in 2013 commenced a project known as the “base erosion and profit shifting” (BEPS)...

Following the financial crisis and ensuing austerity, politicians discovered the problem of tax avoidance. In response, the OECD and G20 launched the Base Erosion and Profit Shifting (BEPS) project in 2013, and this has in October, 2015 culminated with the release of a series of action steps...

The Unified Approach issued by the OECD Secretariat on Oct 9, 2019, is the OECD's most recent attempt to find international consensus on BEPS Action Item 1, “Taxing the Digital Economy.” Our assessment is that the Pillar One proposals in the Unified Approach suffer from several defects, the...
