Abstract:
In this thesis, we use the results of a novel survey of 500 firms from 13 different sectors in Turkish economy and a two-sector general equilibrium model to measure the extent of informality in these sectors through a sectoral analysis as well as in country level. Afterwards, we evaluate the effects of two different policy tools, namely the level of income taxes and the level of tax enforcement on informality. Our results show that both are effective policy tools in tackling informality, enforcement is a steadily effective tool and the effect of taxation, while positive, shifts around depending on the enforcement level.
