This paper aims to assess the extent to which top earners in Ecuador were affected by the COVID-19 crisis compared to other segments of the population. Our analysis uses administrative data for individuals affiliated to social security between January 2019 and December 2021. We identify the top...

I discuss a new approach which decomposes inequality into the contributions of population groups by income sources. I estimate a matrix with rows and columns which indicate different population groups and income sources respectively, with each element indicating the marginal change in the...

This paper presents the findings from a feasibility study on the potential for developing a static tax-benefit microsimulation model for Tanzania. The paper provides an account of the current tax-benefit system in Tanzania and introduces the survey dataset which could function as the...

This paper assesses the feasibility of simulating the distributional impacts produced by various tax and transfer instruments in Viet Nam. Viet Nam's system of tax and transfer policies underwent frequent changes, in terms of diversity and adjustment scope. The most important source of data is...

This paper proposes to understand a singular but salient factor that enables the wealthy to deflect their tax burden downwards: elites' political leverage to shape legislation via their capacity to influence political actors and policy outcomes. The analysis sheds light on alternative mechanisms...

This paper provides an account of a South African tax-benefit microsimulation model - SAMOD - which has been developed for use by government over the past ten years. The two datasets that underpin the current version of SAMOD are introduced, and the model's tax and benefit policies are described...

This paper presents new evidence on the study of income mobility in Ecuador over the period 2004 - 11. We utilize longitudinal data of individual income tax returns to measure income mobility both at the top and at the middle of the income distribution, and we find three main empirical results....

This paper assesses the feasibility of developing a tax and benefit microsimulation model in Mozambique. Mozambique's National Development Strategy 2015-35 commits to providing social security to three-quarters of poor and vulnerable households by 2035. Tax-benefit microsimulation can be used to...

This study presents the findings from a feasibility study on the potential for developing a static tax-benefit microsimulation model for Zambia. The paper focuses on the details of the tax-benefit system and possible data sources, building on information collected in the initial scoping study of...

The aim of this study is to evaluate the feasibility to implement a tax and benefit microsimulation model for Ecuador using EUROMOD as an interface. We first present a detailed description of the main components of the tax and benefit system in Ecuador for year 2014. We then describe available...
