I study the optimal taxation of robots and labor income. In the model, robots substitute for routine labor and complement non-routine labor. I show that while it is optimal to distort robot adoption, robots may be either taxed or subsidized. The robot tax exploits general-equilibrium effects to...

The paper discusses the implications of optimal tax theory for the debates on uniform commodity taxation and neutral capital income taxation. While strong administrative and political economy arguments in favor of uniform and neutral taxation remain, recent advances in optimal tax theory suggest...

The theory of optimal taxation has often been criticized for being of little practical policy relevance, due to a lack of robust theoretical results. This paper argues that recent advances in optimal tax theory has made that theory easier to apply and may help to explain some current trends in...

In reality, avoidance providers are usually either high-skilled specialists or insiders. The strong collusion thus,...

The paper analyses the impacts of occupational choice and entrepreneurial effort on the structure of wage, profit and capital taxation. Entrepreneurial effort is unobservable and therefore not tax-deductible. The optimal profit tax is less than unity even if individual entrepreneurial effort is...

For a small open economy, such as Australia, its living standards (per capita income) are determined by the level of its terms of trade, labour productivity, labour force participation and population. Australia’s terms of trade, labour force participation and population growth are expected to...
