The elasticity of taxable income (ETI) parameter is a key quantity in empirical analysis of tax policy and labor supply. We examine when a commonly applied class of ETI estimands can be used to learn about individuals' ETI parameters and their (un)compensated elasticities of labor supply. We...

This report provides an up-to-date assessment of the scale and distributional impact of tax relief on public, occupational, and private pension contributions in Ireland. Using SWITCH, the ESRI's tax-benefit microsimulation model, we quantify the cost of tax relief under the current...

This paper describes the integration of labour supply behavioural responses into UKMOD, the UK tax-benefit microsimulation model belonging to the EUROMOD family. Traditional static models quantify only the direct ("morning after") fiscal and distributional effects of policy reforms, abstracting...

This paper assesses the fiscal and distributional effects of personal income tax expenditures in Portugal using EUROMOD and 2022 EU-SILC microdata. We compare the 2023 tax-benefit system with a counterfactual scenario in which tax expenditures are removed to estimate first-round impacts. We find...

The taxing authority of subnational governments is limited by the geographic location of individuals and economic activity. The rise of telework decouples a worker's residence from the employer's location, creating challenges for personal income taxes, corporate income taxes, and unemployment...

This paper critically reviews the empirical and structural literature on the effects of income taxation on informal economic activity. Although labor taxation has been widely studied in relation to labor market outcomes, evidence linking income taxes to informality remains fragmented and uneven...

Since its inception, the Welsh Government has had powers over local taxation - determining the structure of council tax (with councils then setting the headline tax rate) and the structure and level of business rates. The late 2010s saw the Welsh Government gain powers over a number of other...

An influential literature suggests that the rise of taxation should come with a 'governance dividend': the quality of government should improve, because the taxpaying citizenry will subject the ruler to increased scrutiny. While this fits the history of nowadays advanced economies, it is less...

Empirical evidence suggests that social acceptance of redistribution depends on whether income differences result from preferences (of which individuals are responsible) or from circumstances. We propose a new empirical method that measures the importance of preferences in the distribution of...

The taxing authority of subnational governments is limited by the geographic location of individuals and economic activity. The rise of telework decouples a worker's residence from the employer's location, creating challenges for personal income taxes, corporate income taxes, and unemployment...

The rare access to exact official geocoordinates opens new methodological possibilities for analyzing highly sensitive tax data. We explore their visualization potential and systematically evaluate aggregation as an anonymization strategy, with particular attention to its methodological and...

I survey the research on the last twenty-five years of subnational income tax policy and conclude that the defining feature of state and local income taxes is geography. Geographic boundaries limit the power of subnational governments to tax people and activities. The article discusses where...

This paper develops an analytical framework for examining land taxation in the context of contemporary urban economies. We dissect the China case for simulation, comparing two model-based scenarios where revenue losses from consumption taxes are replaced by higher income taxes and land taxes. We...

We analyze how value added taxes (VATs) affect labor market outcomes (firms' employee costs, wages, hours worked, employment). While VATs are designed to tax consumption, they are levied at the firm level, which creates potential spillovers to labor markets. We hypothesize that VATs affect wages...

The study examines the shift in taxation of open-ended fixed-income funds in Brazil from a realization basis to an accrual basis (locally known as come-cotas), which was introduced in 1998 and more recently extended to include private closed-end funds and offshore trusts through the enactment of...

This paper extends the sufficient statistics approach to study international tax policy. International policy differs from domestic policies because i.) from the perspective of domestic policy makers the welfare weight on foreign agents lies below that of domestic agents, and ii.) behavioral...

This note examines the effective income tax rates of top earners in Honduras, using a novel approach that links personal and corporate income tax data. This comprehensive income measure, achieved through collaboration with the Honduras Tax Authority (SAR), reveals a crucial link between 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...

In this paper, we investigate the effect of higher personal income taxes on CEO and firm performance in publicly traded US firms. In response to higher taxes on compensation, CEOs are less likely to reach performance goals and spend more time working in boards outside of their firm. At the same...

This report presents results on a review of data available to the State Revenue Committee for estimating the Personal Income Tax and Social Security Contribution gaps. It is concluded that SRC has sufficient quality data available from operational audits to assess the gaps

Joint taxation of married couples represents a puzzle for welfare economics. We investigate whether political economy forces can explain its persistence. We develop sufficient statistics to determine whether a reform towards individual taxation would garner majority support and apply this...

The Scottish Government has a range of tax powers at its disposal, which it has used in recent years to forge an increasingly distinct tax policy from the rest of the UK. In its 2025-26 Budget, the Scottish Government made a number of tax policy changes, including to income tax, business rates,...

Is charitable giving politically motivated? This article uses exhaustive administrative household panel data and a natural experiment to investigate the giving behavior of wealthy households and quantify their preferences for charitable and political donations. Our dataset includes all the...

Die Studie untersucht den Beitrag der unterschiedlichen Einkommensarten, insbesondere der Einkommen aus unselbständiger Beschäftigung zur Finanzierung der öffentlichen Haushalte im Jahr 2019. Neben dem typischerweise dargestellten Aufkommen aus direkten Abgaben (Sozialbeiträge und...

Die Mitte der Gesellschaft wird bei der Einkommensteuer stark belastet. Das ist ein Problem, das von nahezu allen politischen Parteien erkannt wird. Eine Reform scheitert allerdings sowohl an der Frage, wo sich die Mitte befindet, als auch an der Frage der Finanzierung. In diesem Papier...

An often neglected implication of couple taxation is its impact on marital sorting. A tractable model of such an impact is offered in this paper. It reveals that, as compared to joint taxation with income splitting, individual taxation makes higher-ability individuals more picky in the marriage...

We estimate the effects of personal income tax decreases on financial well-being, including qualitative subjective assessments and quantitative measures. A plausibly causal design shows that tax decreases in the Tax Cuts and Jobs Act made survey respondents more likely to say they were “living...

Public disclosure laws on politicians' outside income aim to enhance electoral accountability, but their effects remain unclear and may backfire. Using a German disclosure reform, administrative tax data, and a difference-in-difference design, we show that MPs increased their outside income...

Tax administrations increasingly use audits via mail (correspondence audits) to audit taxpayers. Correspondence audits are cheaper than face-to-face audits but their effects on compliance are unclear. We investigate the effects of correspondence and face-to-face audits on post-audit tax...

I take a simple model of affine taxation of labour income and append to it the possibility that the chosen tax schedule triggers conflict in society. I demonstrate theoretically that, under certain conditions, the set of efficient tax schedules is a proper subset of the set of efficient tax...
