Existing tax schedules are often overly complex and characterized by discontinuities in the marginal tax burden. In this paper we propose a class of progressive smooth functions to replace personal income tax schedules. These functions depend only on three meaningful parameters, and avoid the...

Microsimulation models of the LOTTE system are key tools for tax policy-making in Norway and are extensively used in the budget process. The aim of this paper is to give an overview of the different modules in the LOTTE family - a non-behavioral tax-benefit model for personal income tax...

The paper presents the main characteristics of BETAMOD, a static microsimulation model that reproduces the Italian personal income tax (IRPEF), as well as local income taxes, namely the regional and municipal additional income taxes, building on a detailed reconstruction of tax legislation. With...

Given a settled reduction in the present level of tax revenue, and by exploring a very large combinatorial space of tax structures, in this paper we employ a genetic algorithm in order to determine the ‘best' structure of a real world personal income tax that allows for the maximization of the...

In this paper we explore South Africa's personal income tax system using two microsimulation models. The first, SAMOD, simulates personal income tax and social benefits using a dataset derived from the nationally representative National Income Dynamics Study survey. The second, PITMOD, simulates...

In this paper we explore options for augmenting South Africa's personal income tax revenue using two microsimulation models: PITMOD simulates the personal income tax system and is underpinned by a dataset comprising a full extract of anonymized individual-level administrative tax data; and SAMOD...

This paper documents the impact of voter turnout on top marginal tax rates in the 34 OECD countries for the period between 1974 and 2014. Across a number of specifications, I find that increases in voter turnout have a positive and statistically significant effect on top tax rates. This finding...

The basic deterrence model of tax evasion is described, its main predictions are derived and limitations and flexibility are outlined. Further, the model is interpreted in light of some key institutional features characterising tax enforcement in OECD countries. Throughout the survey, findings...

The origins of fiscal capacity have traditionally been linked to warfare and democratization. However, non-democratic states also invest in fiscal capacity, even in times of peace. In fact, the majority of income taxes-a cornerstone of government finance-were introduced by non-democratic states...
