Sin taxes are increasingly being used to discourage the consumption of goods perceived to harm individuals and society. This paper examines the impact of South Africa's Health Promotion Levy (HPL)-the first sugar tax implemented in Africa-on the consumption of sugar-sweetened beverages (SSBs) in...

We use a natural experiment and administrative data to study the effect of corporate tax cuts on business activity. For identification, we exploit the abolition of municipal corporate income taxation in Sweden in 1985, which created variation in corporate tax changes faced by different...

We study optimal redistribution and carbon taxation in a Mirrlees framework. Households differ in their carbon footprint due to both (i) the overall level of spending and (ii) the composition of spending. Introducing a cap on carbon emissions reduces the social value of output, which lowers the...

This paper examines the efficiency of the Value Added Tax (VAT), focusing on its role as a revenue-raising tool and its use to achieve non-revenue objectives. The analysis highlights the VAT's potential ability to generate revenue with minimal distortions, emphasizing its advantages over...

We use variation in marginal tax rates and in tax bracket thresholds at which they apply in order to identify the substitution and income effects of tax reforms. We use a triple-difference estimator that exploits variation from subnational tax reforms, for which behavioral responses to taxes are...

This paper characterises the Laffer curve of each individual taxpayer in a schedular multirate income tax with income shifting. Analytical expressions for the revenue-maximising tax rate and the revenue-maximising elasticity are provided for the individual taxpayer and the aggregate population,...

We study how corporate taxation interacts with intra-firm incentive conflicts between shareholders and managers and how this interaction impacts the firm’s economic decisions and outcomes. In our model, investment under asymmetric information facilitates entrenchment and rent extraction by the...

We analyze non-cooperative commodity taxation in a symmetric two-country trade model characterized by monopolistic competition and international firm and capital mobility. In this setting, taxes in one country affect foreign welfare through the relocation of mobile firms and through changes in...

Taxation affects the allocation of talented individuals across professions by blunting material incentives and thus magnifying non-pecuniary incentives of pursuing a “calling.” Estimates from the literature suggest high-paying professions have negative externalities, whereas low-paying...

The upcoming one-year repeal of the federal estate tax creates an opportunity to reconsider the taxation of wealth transfers. This paper argues that federal wealth transfer taxes should be retained and potentially expanded. The estate tax contributes importantly to the progressivity of the tax...
