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...

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

We adopted an empirical approach to capture the macroeconomic impact of tax changes for the examined period from 1974 to 2018. It is generally accepted that vector autoregression model (VAR) has proven useful for describing the dynamic interrelationships of multivariate series. Our empirical...

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,...

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...

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...

South Africa is one of the most unequal economies globally. In this paper, we examine the design of its personal income tax (PIT), with a focus on its redistributive function. We apply the Pfähler decomposition method to analyse the redistributive effects of key components of the South African...

This paper tests whether partially unemployed workers value future preserved benefits when they bunch at the kink of the unemployment insurance benefit-withdrawal schedule. I extend the bunching formula of Saez (2010) to a dynamic setting that accounts for the value of future benefits tied to...

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...

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 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...

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...

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...

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...

Flat tax systems have gained traction in countries that transitioned from socialism, with more than 20 nations in Eastern Europe and Central Asia adopting such systems since the mid-1990s. These reforms aimed to streamline tax processes, enhance compliance, and boost economic growth. While...

Immigration may affect income inequality not only by changing factor prices but also by inducing policy makers to adjust the prevailing income tax system. We assess the relative importance of these economic and political channels using administrative data from Switzerland where local authorities...

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...

In a dual income tax (DIT) system, labor income is taxed progressively, while capital income is subject to a lower proportional tax. DIT systems were introduced in Sweden, Norway, and Finland in the early 1990s. In the absence of rules restricting capital income distributions, owners of...

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...

Immigration may affect income inequality not only by changing factor prices but also by inducing policy makers to adjust the prevailing income tax system. We assess the relative importance of these economic and political channels using administrative data from Switzerland where local authorities...

We decompose earnings risk into contributions from hours and wage shocks. To distinguish between hours shocks, modeled as innovations to the marginal disutility of work, and labor supply reactions to wage shocks we formulate a life-cycle model of consumption and labor supply. For estimation we...
