a new mathematical model for the optimal production isformulated for the inventory management system under time-varyingand stochastic inflation environment for deteriorating items. the timehorizon is finite and demand rate is dependent to the inflation. in thereal situation, some but not all customers will wait for backlogged itemsduring a shortage period, such as for fashionable commodities or...

the issue of this paper is the relationships between inflation rate , unemployment rate and production, one of the main discussions in macroeconomic models. this 'paper is an effort 'to determine the relationship between the above- mentioned phenomenon in the short-and in the long 11m as well as to calculate the natural rate of unemployed in iran. for this purpose, the theoretical mod...

this paper estimates the determinants of inflation in iran using a linear and non- linear regression model over the period 1959-2008. in the model specification, the conventional variables (liquidity, production and exchange rate) as well as positive and negative oil revenue shocks, monetary disequilibrium, and demand gap are considered. the results show that nonlinear time series regression mo...

O ne of the more important challenges facing policymakers is that of assessing inflation expectations. Goodfriend (1997) points out that one can interpret the meaning of a given interest rate policy action primarily in terms of its impact on the real rate of interest. However, evaluating this impact requires not only that one understands the various links between the nominal rate and expected i...
