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...

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...

This paper examines income tax systems in over thirty countries over the past forty years using microdata from the Luxembourg Income Study. We show that income tax systems worldwide are well approximated by a two-parameter log-linear effective tax function. We provide country- and year-specific...

We examine the role of owner-occupied housing for income inequality. Departing from related work, we incorporate accrued capital gains, focus on long-run measures of income, and consider implications for tax progressivity. Using Australia as a case study, we show that housing income can have...

This study analyzes whether the tax progression proviso's calculation method for foreign income exemptions under a tax treaty breaches EU law. This research question has not yet been examined in the literature. In such a case, a violation of the EU fundamental freedoms may result in taxpayers...

We link French households' tax records to the corporations they control, and build a payout-policy-neutral income measure, with corresponding tax burdens including those of "billionaires": the top 0.0002%. Defined as such, income is more concentrated than taxable income, it better predicts...

The implementation of capacity development (CD) advice and reforms since a 2018 TADAT assessment shows slower progress than expected. Renewed recommendations suggest initiating a transformation program for integrated reform

Im Rahmen dieses Projektes wurde gemeinsam mit dem Institut für Höhere Studien die Höhe der kalten Progression in Österreich geschätzt. Diese Berechnungen begründen die Grundlage für die Indexierung des Steuersystems im folgenden Jahr.

This paper presents a novel approach to addressing VAT regressivity, by proposing the adoption of a progressive VAT: a single-rate, broad-base, VAT, whereby tax paid on consumption is re-paid to lower income households in real-time, at the moment of purchase. Such a system can effectively...

Seit dem Jahr 2016 wurde der Einkommensteuertarif jährlich an die Inflation angepasst, um die sonst automatisch steigende durchschnittliche Belastung der Einkommen - die "kalte Progression" - auszugleichen. Zu diesem Zweck wurden Grundfreibetrag und Tarifeckwerte verschoben, sodass die...

Many countries have automatic wage tax withholding systems with tax non-filing options for some taxpayers. We show that this has sizable and potentially unintended implications for effective taxation because taxes are often over-withheld. Low-income taxpayers pay more taxes than they have to...

This chapter examines the implications of Artificial Intelligence (AI) and automation for the taxation of labor and capital in advanced economies. It synthesizes empirical evidence on worker displacement, productivity, and income inequality, as well as theoretical frameworks for optimal...

In this study, we examine the behavior of self-employed taxpayers who "bunch" at an income level just below a critical threshold, which triggers a transition from a simple tax regime to a more complex one. Under the simple regime, individuals complete their tax forms independently, while the...
