The LOTTE system of tax microsimulation models

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 (LOTTESkatt), a labor supply model (LOTTE-Arbeid), and a model for distributional effects of commodity taxation (LOTTE-Konsum). In addition to providing descriptions of the designs of the three microsimulation models, we give examples of how the models are used in practical and academic work.
