ABSTRACT:This paper examines the efficiency of the Value Added Tax (VAT), focusing on its role as arevenue-raising tool and its use to achieve non-revenue objectives. The analysis highlights the VAT's potentialability to generate revenue with minimal distortions, emphasizing its advantages over alternative taxes, such asturnover taxes and tariffs, particularly in minimizing the cascading effects of input taxation. The paper alsoexplores the VAT as a macroeconomic policy tool, especially in counter-cyclical fiscal policy, and its potential toaddress environmental and health objectives. It concludes that a well-designed and implemented VAT is ahighly efficient revenue-raising tool, surpassing other forms of consumption taxation, but cautions against itsmisuse in industrial policy and other contexts for which it is ill-suited.

The most fundamental purpose that the VAT serves, of course, is raising revenue: Efficiency inthis dimension, and the related question of whoit is that really pays the VAT, are the subject of the first part ofthis paper (Secti
