Definition: This method of estimating the size of the informal economy is based on a Dynamic General Equilibrium model where economic agents can allocate time and effort in the formal and the informal sector. Their allocation decision is driven by model parameters such as government spending and taxation. The theoretical model is calibrated to arrive at a measure of the size of the informal economy. The estimate is put to further robustness tests. See Elgin and Oztunali (2012) for further methodological detail.
