Tony Addison January saw the snow arrive in Helsinki. As I look out across the harbour, the scene is one of various shades of white and grey. The...
Tony Addison It’s now February, and Helsinki remains deep in snow. We had an extended blizzard last weekend, with temperatures hovering around minus...
Tony Addison As we come to the end of November, the snow has yet to arrive in Helsinki. We continue to enjoy clear skies and spectacular sunsets...
Tony Addison Today, there is much frustration with the financial sector. Society’s precious savings are not being put to the best of uses—investing...
Qualitative case studies suggest that the outcomes of tax treaty negotiations are determined by power politics and negotiating capability. In contrast, quantitative studies have tended to depart from a model that implies absolute gains, full...

Based on a unique panel dataset consisting of both formal and informal firms surveyed every other year from 2005 to 2013, this paper explores the benefits of formalization to the government and firm employees in Vietnam. We find that formalization...
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...
The theoretical analysis of optimal commodity taxation is advanced, but there is only limited empirical evidence to guide commodity tax policies. With this paper, we contribute to this body of literature by empirically examining, using Finnish...
The Mirrlees Review recommends that commodity taxation should in general be uniform, but with some goods consumed in conjunction with labour supply (such as child care) left untaxed. This article examines the validity of this claim in an optimal...
We study a model of human capital driven growth, where the parent’s human capital serves as a productive input in the child’s human capital production only when that of the former exceeds a minimum level required to intellectually contribute to the...
Brazil’s recent growth has been intensely pro-poor, and both poverty and inequality have declined significantly in the last decade. It has been suggested that Brazil’s unexpected successes are the outcome of a new model of development. The paper...
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...
This paper examines the effects of health-oriented food tax reforms on the distribution of tax payments, food demand and health outcomes. We offer an illustration of how one can take into account the uncertainty related to both demand estimation and...
This paper analyses the consequences of formalisation on the performance of informal firms, using a panel dataset from Vietnam. We find that switching firms (before switching) have higher profit and value added compared to non-switching firms...

A large informal sector is a challenge for developing countries building up social protection systems. Expanding social safety nets reduces poverty, but financing them can increase the tax burden, potentially reducing availability of formal sector...
This paper uses income and expenditure surveys from 1992 to 2014 and public tax and spending accounts to estimate the redistributive impact of Mexico’s fiscal system over this period. It presents standard and marginal benefit incidence analysis for...
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...
Growth, poverty reduction, and social peace are all undermined when public expenditure management and taxation are weak and when the fiscal deficit and public debt are not managed successfully. And large-scale aid and debt relief cannot work without...
The main argument of this paper is that there is considerable heterogeneity in the way aid can shape tax performance in developing countries: through behavioural effects, donor conditionality, recipient policy reform and technical assistance; and...
An important feature of aid to developing countries is that it is given to the government. As a result, aid should be expected to affect fiscal behaviour, although theory and existing evidence is ambiguous regarding the nature of these effects. This...
Almost twenty years have passed since researchers from the Institute for Liberty and Democracy in Peru showed how ‘bad laws’ impose disproportionate costs on those who choose formality. Although a multitude of conflicting regulations still precludes...

Let’s face it, data is important. It sits at the core of almost everything that we in the development economics research community do. However, the...
The Nordic model relies on high tax rates to finance an extensive welfare state. If labour supply elasticities are large, the burden of financing the model can be large even if, arguably, the practice of providing subsidised goods that support labour...
This paper reviews income distribution in developing (and transition) countries in recent decades. On average, before-tax income distribution is less unequal in developing countries than it is in industrial countries. However, unlike industrial...
The sculpture below in Mexico City is called ‘El Ángel de la Securidad Social’ (The Angel of Social Security) and was created by Jorge Marín in 2013...
The recent rise in inequality in the distribution of disposable income in many, although not all, countries has led to a search for explanations, particularly since for much of the postwar period falling inequality has been the norm. In OECD...
In recent years many global firms—including Starbucks, Google, and Amazon—have come under fire for avoiding paying taxes in one country by shifting...
Understanding the development effects of official aid is crucial to building a better bridge between research and policy. This paper reviews the current evidence regarding the impact of aid on growth and poverty reduction, and develops a new...

This journal presents a synopsis of the contextual conditions, factors and challenges under which the recent evolution of tax systems has taken place, as an introduction to this United Nations University-World Institute for Development Economics...

Do intergovernmental transfers reduce revenues collected by local government authorities (LGAs)? There is already a well-established body of literature in public finance, which argues that intergovernmental grants “crowd out” local revenues. Most...
This paper examines the impact of the introduction of the value-added tax on inequality and government revenues using newly released macro data. We present both conventional country fixed effect regressions and instrumental variable analyses, where...
This paper investigates the effects of taxation on income inequality in an unbalanced panel of 45 countries in sub-Saharan Africa over the period 1980–2018. We use instrumental-variable two-stage least squares and instrumental-variable quantile...
This paper constructs time series of global profit shifting covering the 2015–19 period, during which major international efforts were implemented to curb profit shifting. We find that (i) multinational profits grew faster than global profits, (ii)...

The importance of domestic revenue mobilization and taxation for sustainable development is widely acknowledged in global development discussions, but...
The aims of this paper are twofold. It firstly identifies and discusses the extent to which public revenues from natural resources are adequately captured in existing cross-country revenue databases, before exploring the extent to which such data can...
About a decade ago, the world’s biggest economies agreed to crack down on multinational corporations’ abusive use of tax havens. This resulted in a 15...
