This paper describes IZAΨMOD, the policy microsimulation model of the Institute for the Study of Labor (IZA). The model uses household microdata from the German Socio-Economic Panel Study and firm data from the German linked employer-employee dataset LIAB. IZAΨMOD consists of three components:...

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....

The purpose of the paper is to provide a discussion of the various approaches for accounting for labour supply responses in microsimulation models. The paper focuses attention on two methodologies for modelling labour supply: the discrete choice model and the random utility - random...

In-work transfers are often seen as a good trade-off between redistribution and efficiency, as they alleviate poverty among low-wage households while increasing financial incentives to work. The present study explores the consequences of extending these transfers in Ireland, where support for...

Microsimulation methods and models of labor market decisions have attracted a lot of attention as an approach to the assessment of consequences of family related policies in the area of labor market and fertility. We set these models in the context of relevant demographic theories and present...

We analyze the labor supply and income effects of a needs-based minimum benefit system ("Bedarfsorientierte Mindestsicherung") to be introduced in Austria by the end of this/beginning of next year. The aim of this reform is to reduce poverty as well as increasing employment rates of recipients...

This paper describes IZA[psi]MOD, the policy microsimulation model of the Institute for the Study of Labor (IZA). The model uses household microdata from the German Socio-Economic Panel Study and firm data from the German linked employer-employee dataset LIAB. IZA[psi]MOD consists of three...

This paper advances a structural inter-temporal model of labour supply that is able to simulate the dynamics of labour supply in a continuous setting and to circumvent two main drawbacks of most of the existing models. The first limitation is the inability to incorporate individual heterogeneity...

This paper contributes to the debate about the optimal design of tax-transfer systems. Based on the theory of optimal taxation, combined with microsimulation and microeconometric techniques we derive the welfare function which makes the current German tax and transfer system for single women...
