After 162 years of political unification, Italy still displays large regional economic differences. In 2019, the per capita GDP of Lombardia was 39,700 euros, but Calabria's per capita GDP was only 17,300 euros. We build a two-region, two-sector model of the Italian economy to measure the wedges...

In a model with ex-ante homogenous households, earnings risk and a general earnings function, we derive the optimal linear labor tax rate and optimal linear education subsidies. The optimal income tax trades off social insurance against incentives to work and to invest in human capital....

In this paper, we analyse the role of mobility in tax and subsidy competition. Our primary result is that increasing "relocation" mobility of firms leads to increasing "net" tax revenues under fairly weak conditions. While enhanced relocation mobility intensifies tax competition, it weakens...

This paper shows that subsidy competition may be efficiency enhancing. We model a subsidy game among two asymmetric regions in a new trade model, where capital can freely move among regions, but capital rewards are repatriated. We study subsidy competition, starting from an equilibrium where the...

This paper provides a rationale for subsidizing green (renewable) energy production. Within a multi-country model where energy is produced with mobile capital in green and dirty production, we investigate the countries' decentralized choice of emissions taxes and green energy subsidies. Without...

This paper develops sufficient conditions under which the Weak Green Paradox may (and may not) hold in terms of subsidies for biofuel production such that the supply-side responses by fossil fuel producers may more than offset the substitution to biofuels. Analytical results are derived and...

Assuming a two-period model with endogenous choices of labour, education, and saving, efficient education policy is characterized for a Ramsey-like scenario in which the government is constrained to use linear instruments. It is shown that education should be effectively subsidized if, and only...

Given that credit and insurance markets are imperfect, and given also that intra-household transfers, and much of the work a child does, are private information, the second-best policy uses a combination of need and merit based education awards, together with a mix of taxes on parental income,...

Atkinson and Stiglitz (Journal of Public Economics 1976) show that when the government has access to non-linear income taxation and consumer preferences are separable between consumption and leisure, there is no need for differentiated commodity taxation. This paper examines the empirical...
