Abstract: The objective of model-building was an inflation model suitable for prognosis as well as for simulation. The model serves two purposes. First of all, it is a tool for analysing inflation. Secondly, it is part of the model of Estonian economy, which completes the adjustment loop of the macromodel. The theoretical background of the inflation model derives from four basic features of Estonian economy. Namely, Estonia is: a small and open economy, a transitional economy, economy under currency board arrangement and a market economy. When estimating the model, inflation was decomposed into a) underlying inflation which is a long-run process and b) inflation deviations from the equilibrium which are caused by the short-run impact of inflation factors. The underlying inflation, which reflects the convergence, is determined as a trend. The latter was specified as a time function, ARMA process, moving average and HP filter, whereas the best result was obtained with time function. According to modelling output the short run dynamics of the inflation are determined by three main factors - demand pressure reflected by the GDP gap, exchange rate of the US dollar (which is proxy for foreign prices), and administrative action for correcting regulated prices. The adequacy of the model has been tested on the basis of ex post and ex ante prognosis. The model provided acceptable results in the simulation of endogenous and exogenous shocks
