In a recent contribution, H. Naito (1999) has shown that production efficiency may be violated in the optimum with non-linear income taxation. Using a slightly simpler framework, this paper complements Naito's analysis in showing that production efficiency does not hold in the optimum with (i)...

Policies that impact the production sector, such as intermediate goods taxation (e.g. taxing robots) and trade liberalization create winners and losers. When do we need to integrate pre-distribution concerns in the design of these production policies? Should we consider the endogenous changes of...

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...

We propose a new approach to assess the impact of regulatory changes on the production sector such as competition policies, taxing intermediate goods, robots or AI, trade regulation, production of public firms or environmental standards for firms. Our framework covers multidimensional nonlinear...

We study nonlinear income taxation in a Roy model in which agents' productivity is sectorspecific. We show that when income taxes can be sector-specific, the Diamond-Mirrlees theorem (according to which the second-best displays production efficiency) fails: social welfare (be it Rawlsian or...

In this paper it is shown that allowing the deduction of work-related expenses has a strictly positive effect on tax efficiency only if two conditions hold jointly: (i) The expenses should be interpretable as real cost and (ii) the expenses should be required for increasing taxable income....

The desirability for production efficiency is re-examined in this study, where agents choose occupation based on lifetime income net of tuition costs. Efficient revenue raising implies that the government should trade off efficiency in production for efficiency in intertemporal consumption, as...

Differentiated tax rates on labor and capital income are found to be optimal in this study, where agents choose occupation based on lifetime income net of tuition costs. Efficient revenue raising in a case where the government can not observe educational effort implies that the government should...

Consider a simple general equilibrium economy with one representative consumer, a single competitive firm and the government. Suppose that the government has to finance public expenditures using linear consumption taxes and/or a lump-sum tax on profits redistributed to the consumer. We show...
