The digitalization of transaction processes through tools such as electronic invoicing (e-invoicing) aims to improve tax compliance and reduce administrative costs. Another important aspect of digitalization is its potential to reduce tax evasion. We analyze the impact of the widely introduced...

When deciding on the social desirability of public investment, the cost of a project is sometimes adjusted by a factor known as the Marginal Cost of Public Funds (MCPF) which captures the cost of raising public funds through distortionary taxation. However, there is no scholarly consensus on...

I consider the case for the minimum wage alongside (optimal) income taxes when workers differ in both wages and working hours, such that a given level of income corresponds to multiple wage rates. The minimum wage is directly targeted at the lowest-wage workers, while income taxes are at most...

This study examines the effects of the tax structure composition for public sector efficiency in a sample of 41 developing countries for the period between 1997-2019. We start by calculating Public Sector Performance (PSP) composite indicators and use them as outputs to compute data envelopment...

This paper introduces life expectancy inequality into a tractable Mirrleesian life-cycle model and characterizes the optimal income tax policy using theory and calibration. A positive association between life expectancy and income counteracts the well-known static pattern of declining marginal...

We develop a theory of tax reforms for a setting with multi-dimensional heterogeneity amongst taxpayers and multiple economic decisions that are all subject to fixed and variable costs. The theorems in this paper provide a complete characterization of the conditions under which Pareto- or...

This paper analyzes the welfare implications of children’s enfranchisement within a political economy framework that emphasizes the trade-offs in public policy when the electorate includes different age groups. Public spending is financed by tax revenues, meaning that higher spending on...

We study the optimal taxation of expenditures that generate income while also serving a consumption function. We characterize the Pareto optimal income tax deduction for such mixed-purpose expenditures within a generalized Atkinson-Stiglitz model. Pareto optimality requires a partial deduction...

Tradable black (CO2) and green (renewables) quotas gain in popularity and stringency within climate policies of many OECD countries. The overlapping regulation through both instruments, however, may have important adverse economic implications. Based on stylized theoretical analysis and...

This paper studies the optimal income redistribution and optimal monitoring when disability benefits are intended for disabled people but when some able agents with high distaste for work mimic them (type II errors). Labor supply responses are at the extensive margin and endogenous take-up costs...
