The Tobacco Excise Tax Simulation Model (TETSiM) is a tool to quantify the likely impact of a change in the excise tax structure and/or the level of the excise tax on a number of variables, including the price of cigarettes, cigarette consumption and excise tax revenue. Programmed in Excel, it provides a customisable model of the excise tax system for individual countries. The degree of complexity of the model depends on the structure of the excise tax system, and the availability of appropriate data. In principle, any person with Excel programming skill can develop a TETSiM model for their country. However, some tobacco excise taxation experience is useful, especially if the tax or pricing system is quite complicated. All researchers at REEP have been trained in the TETSiM model and can help officials develop their own country models.
