t his paper investigates the asymmetric behavior of inflation. we use logistic smooth transition autoregressive (lstar) model to characterize the regime-switching behavior of iran’s monthly inflation during the period may 1990 to december 2013. we find that there is a triple relationship between the inflation level, its fluctuations and persistence. the findings imply that the behavior of infla...

depending on the assumptions that are made in new keynesian models, one can attain different new keynesian phillips curves. in this study, three different new keynesian phillips curves and two different central bank behavioural functions are presented which leaves six new keynesian dsge models to study. the purpose of this study is the comparison of these six models and selecting the best model...

the main goal of this research is studying the causative & effect of deficit budget, money offering and inflation rate in iran during 1360-1390. the results in long time indicates that the bulk of money has had positive effect & meaning on inflation rate during that time and alteration of budget deficit of the government has also positive effect on inflation but by meaningless impress, in other...

study of price trend in iran, showed that general level of prices is rising continually during time. an inflation situation has effect on most economic variables. therefore investigation of effective factors and variables on inflation is important. exchange rate and gap in product are factors which affect inflation. in this paper the impact of exchange rate shocks and gap on inflation in iran’s...

We forecast US GDP and inflation over 1-, 4and 8-step horizons using the dataset from Stock and Watson (2009), with factors, variables, both, and neither. Autometrics handles perfect collinearity and more regressors than observations, enabling all principal components and variables to be included for model selection, jointly with using impulse-indicator saturation (IIS) for multiple breaks. Emp...

The influence of recent global shocks such as the COVID-19 pandemic and Russian–Ukrainian war on variability major macroeconomic trends not only shows synchronized behavior across economies but also induces similar policy responses to counter these shocks. purpose this article is explore transmission inflation among G20 evaluate its contribution domestic inflation. To end, we use Diebold Yilmaz...

this paper empirically investigates the relationship between cpi inflation uncertainty, and private investment in the iranian economy from 1988 to 2010 by using quarterly data. we employ a bivariate var(5)-garch(1,1)-in-mean with diagonal bekk model to discover in a unified framework how are the interactions between the variables. in the model, conditional variance of inflation and private inve...
