Despite the criticality of tax administration (TA) reforms in enhancing domestic revenue mobilization, few studies have attempted to quantify the revenue impact of such reforms. This paper fills this gap by estimating the revenue yields associated with various tax administration capabilities,...

Many countries face the challenge of raising additional tax revenues without hurting economic growth. Comprehensive, cross-country information on the revenue impact of tax policy changes can thus support informed decision-making on viable reforms. We assess the likely revenue impact of various...

This paper presents estimates of the size of the shadow economy in 76 developing, transition, and OECD countries, which are derived by combining figures from different estimation methods. We describe and discuss the strengths and weaknesses of the different estimation methods. We find that the...

In recent years the level of taxation of many developing countries has changed dramatically over relatively short periods. These changes are too large and too sudden to attribute fully to a deterioration in tax administration or to changes in the traditional determinants of tax levels. The paper...

This paper examines the role of tax administration in developing countries from an economic perspective. The traditional separation of tax policy and tax administration in the literature is shown to break down in developing countries, where tax administrators decide in what manner complicated...

This paper discusses important tax policy issues facing developing countries today. It views tax policy from both the macroeconomic perspective, which focuses on broad questions such as the level and composition of tax revenue, and the microeconomic perspective, which focuses on certain design...

Issues of taxation and development, which have long been a central concern of the IMF, have attracted wider and renewed interest in the last few years. This paper reflects on three broad lessons of experience: that developing countries differ vastly in tax matters, and in ways that are less than...

This paper studies tariff-tax reforms in a calibrated two-region global New Keynesian model composed of a developing and an advanced region. In our baseline calibration, a revenue-neutral reform that lowers tariffs in developing countries can reduce domestic welfare. The reason is that the...

We investigate the impact of remittances on public debt sustainability and detail how the traditional debt-to-GDP ratio can be modified to create a more accurate representation of debt sustainability for a country that receives significant remittance inflows. The main result is that inclusion of...
