Dual-regime business tax systems typically subject smaller firms to an output (turnover) tax and larger firms to a profit (corporate) tax. Despite their prevalence, there is little formal analysis of their optimal design. This paper addresses this gap by developing a theoretical framework to...

The paper analyses commodity taxation in an economy where a good can be recycled. Consumers deliver units of a used good to a reuse operator, who sells the good in a second-hand market after some processing. Two regimes are considered. One is a pure market setting where the reuse operator pays...

Raising the retirement age is a common policy response when social security schemes face fiscal pressures. We develop and estimate a dynamic life cycle model to study optimal retirement and tax policy when individuals face health shocks and income risk and make endogenous retirement decisions....

Purpose: The present paper analyzes the current situation of taxation of financial services, pointing out the main alternative taxation methods. Design/methodology/approach: It is carried out an analysis of them, through the application of all of them to the same numerical example. Originality:...

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...

To study the economic and welfare consequences of alternative time paths towards net zero CO2e emissions, we develop a multi-sector dynamic computable general equilibrium model of an open economy with heterogeneity in abatement costs across sectors and firms and with adjustment costs in the...

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...

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...

Adaptation is omnipresent but people systematically fail to correctly anticipate the degree to which they adapt. This leads individuals to make inefficient intertemporal decisions. This paper concerns optimal income taxation to correct for such anticipation-biases in a framework where consumers...
