We develop a behavioural micro simulation model (LuxTaxBen) that contains very precise information on income tax rules, as well as eligibility-rules for a number of welfare programs, such as social assistance, housing allowance etc. The model has been built specifically for analysing the...

Globalization and automation might imply deep changes on the labour market. An important policy issue is whether and how the tax-transfer rules should be reformed to cope with those changes. While the prevailing response has consisted of more sophisticated designs of mean-testing and targeting,...

We present an exercise in empirical optimal taxation for European countries from three areas: Southern, Central and Northern Europe. For each country, we estimate a microeconometric model of labour supply for both couples and singles. A procedure that simulates the households' choices under...

We use a behavioural microsimulation model embedded in a numerical optimization procedure in order to identify optimal (social welfare maximizing) tax-transfer rules. We consider the class of tax-transfer rules consisting of a universal basic income and a tax defined by a 4th degree polynomial....

We present an extension of the numerical approach to empirical optimal taxation allowed by a peculiar structure of a microeconometric model of labour supply that includes a representation of the demand side. This makes it possible to identify optimal tax-transfer rules while accounting for...

In this paper we propose a tax and benefit reform to increase the working hours and to decrease the welfare participation of single mothers in Sweden. We have access to highquality tax and income data, and use a detailed tax-benefit program to generate precise budget-sets. We formulate and...

In this paper, we formulate and estimate a structural, static model of household labor supply and multiple welfare program participation. Given the complicated nature of both the income tax schedule and the benefit rules for different welfare programs, we use unique access to a very detailed...

The purpose of this paper is to evaluate a recent Swedish in-work tax credit reform where we pay particular attention to labor market exclusion; i.e. individuals in as well as outside the labor force are included in the analysis. To highlight the importance of the joint effects from the tax and...

The purpose of SWEtaxben is to evaluate the impact of changes in the tax/benefit systems on households as well as the central governmental budget. Relating to the micro simulation literature this model can be labeled a static micro simulation model with behavioral changes. This behavioral change...

This paper follows the theory of optimal taxation and the goal is to identify a tax/benefit design that maximizes social welfare. A two stage process is proposed where the individuals preferred choice of leisure and consumption is solved in the first stage, and the second stage identifies the...
