This authoritative monograph explores the effectiveness and transferability of the rapidly expanding range of policy approaches and measures available as weaponry in the fight against the shadow economy. Beginning with a review of the extent of undeclared work, the author discusses the discrepancies between regions and the potential impacts of the economic crisis, comparing the nature of the potential solutions available with those actually adopted. rnrnThe way forward, the book concludes, is to move away from increasing the costs of engaging in hidden work using repressive measures, and concentrate more on developing initiatives that enhance the benefits of engaging in declared work and increase the likelihood of compliance by engendering a commitment to tax morality. This insightful and unique exposition will have considerable appeal to academics, practitioners and policy-makers across the globe involved in the fight against undeclared work.
