An empirical finding by Gaspar, Jaramillo and Wingender (2016) shows that once countries cross a tax-to-GDP threshold of around 12¾ percent, real GDP per capita increases sharply and in a sustained manner over the following decade. In this paper, we attempt via four case studies - Spain, China,...

Growing regional inequality within countries has raised the perception that 'someplaces and people' are left behind. This has prompted a shift toward inward-looking policies andaway from pro-growth reforms. This paper presents novel stylized facts on regional inequality forOECD countries. It...

Distribution neutral fiscal policy refers to a structure of taxes and transfers that keep the income distribution unchanged even after positive or negative shocks to an economy. This is referred to as a Strong Pareto Superior (SPS) allocation which improves the standard Pareto criterion by...

This paper shows that donors that maximize relative aid impact spread their budgets across many recipient countries in a unique Nash equilibrium, explaining aid fragmentation. This equilibrium may be inefficient even without fixed costs, and the inefficiency increases in the equality of donors'...
