This paper explores the revenue-raising aspect of progressive taxation and derives, on the basis of a simple model, the optimal degree of tax progressivity where the tax revenue is used exclusively to finance (perfectly) targeted transfers to the poor. The paper shows that not only would it be...

Spain's structural reforms, implemented around 2012, have arguably contributed to a faster and stronger economic recovery. In particular, there is strong evidence that the 2012 labor market reforms increased wage flexibility, which helped the Spanish economy to regain competitiveness and create...

Is there a one-size-fits-all approach to inclusive growth? We look at four key case studies across advanced and emerging markets-the Nordics, India, Brazil, and Egypt-to try to answer this question. We highlight qualitatively in these countries the key components of inclusive growth models,...

Using micro-data from household expenditure surveys, we document the evolution of consumption poverty in the United States over the last four decades. Employing a price index that appears appropriate for low income households, we show that poverty has not declined materially since the 1980s and...

We analyze microdata from Mexico's survey on household income and expenditures (ENIGH) to study the evolution of income inequality in Mexico over 2004-16, identify its sources, and investigate how it was affected by government social policy. We find evidence of only a small decline in inequality...

This paper discusses the definition and modelling of a universal basic income (UBI). After clarifying the debate about what a UBI is and presenting the arguments in favor and against, an analytical approach for its assessment is proposed. The adoption of a UBI as a policy tool is discussed with...

This paper challenges the conventional wisdom that inequality in Poland increased markedly during the economic transition. Income and consumption inequality actually declined in 1990-92 and rose only moderately above pre-transition levels by 1997. However, inequality in labor earnings increased...

This paper presents a novel technique to measure and compare the redistributive capacity of observed tax (or transfer) policies. The technique is based on income distribution simulations and controls for differences in pre-tax income distributions. It assumes that the only information on the...

This paper assesses a possible explanation for the global downward trend in top personal income tax rates over the last decades: globalization and the related tax evasion and avoidance opportunities could have raised elasticities of taxable income, which would imply lower optimal tax rates. The...

This paper discusses how the structure of the tax system affects its progressivity. It suggests a measure of progressive capacity of tax systems, based on the Kakwani index, but independent of pre-tax income distributions. Using this and other progressivity measures, the paper (i) documents a...
