In the tax literature, the tax effort index for any country is usually measured by the ratio of the actual tax ratio to the predicted ratio. This reflects mainly the variance in the taxable capacity of a country. A high value of tax effort index indicates that a particular country is collecting...

This paper measures the tax effort of a sample of fifty-nine developed and developing countries over the period 1995-2015 by comparing a country's actual tax/GDP ratio with the ratio predicted derived from an international tax function which relates tax revenue to various measures of a country's...

The term fiscal resource curse refers to countries' inability to raise taxes from a broad base in the presence of natural resources. We employ a novel instrumental variable strategy to estimate the causal effect of resource revenues on non-resource tax effort by exploiting the so-called 'China...

This paper attempts to extend the theoretical and empirical methodology employed in previous literature, by proposing a utility maximization process to estimate the optimal tax revenue from a sample of 30 countries. It is shown that an optimal tax system is defined solely by two crucial...

The purpose of this paper is to examine the various structural determinants of revenue and tax effort in Tunisia. We used on the empirical study an ARDL model to estimate the dynamic equation of fiscal potential and its structural and non-structural determinants covering the period of 1996-2017...

This paper empirically analyses the effects of the tax complexity and other elements, such as natural resource revenues, public expenditure, and the capacity of the statistical system, on the efficiency of Ecuadorian Customs Administration. For this purpose, the methodology used consists of...

Attention on domestic resource mobilization-particularly in developing countries- has increased significantly in recent years. This stems from, among other things, recognition in the Sustainable Development Goals that further domestic funding is required for development needs, and the Addis Tax...

This paper investigates the effect of ICT and e-formalization on tax mobilization efforts in sub-Saharan Africa. Using a panel of 42 countries from 1991 to 2018 and applying appropriate model specifications; the empirical findings show that there is strong support that ICT (mobile subscription...

This paper describes the estimation of a new tax effort index for 120 developing countries over 1990-2012. Two major innovations are the use of a new measure of non-resource tax revenues and the correction of the traditional method of tax effort estimation by accounting for structural economic...

Several African countries have to increase their tax revenues to finance human and economic development. General consumption taxes, such as VATs, are the preferred instrument for doing so, because they are less detrimental to growth than income taxes. To enable their use, VAT design has to be...
