The paper presents a detailed description of the ISMIK model which was developed as a part of "Priority project TÁMOP - 2.3.2-09/1 Establishing labour market forecasts and foreseeing structural changes". The ISMIK model is a dynamic microsimulation model to project individuals' educational...

The so called classic model of tax compliance behaviour interprets the problem as an individual decision under risk made by a single taxpayer. After a concise description of this model our literature survey investigates whether the empirical results found in the literature corroborate the...
