Asymmetric Behavior of Inflation in Iran: New Evidence on Inflation Persistence Using a Smooth Transition Model
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 behavi...
متن کاملA Smooth Transition GARCH Model with Asymmetric Transition Phases
This paper develops a smooth transition GARCH model with an asymmetric transition function, which allows for an asymmetric response of volatility to the size and sign of shocks, and an asymmetric transition dynamics for positive and negative shocks. We apply our model to the empirical financial data: the NASDAQ index and the individual stock IBM daily returns. The empirical evidence shows that ...
متن کاملMultilaminate Elastoplastic Model for Granular Media
A multilaminate based model capable of predicting the behavior of granular material on the basis of sliding mechanisms and elastic behavior of particles is presented. The capability of the model to predict the behavior of sand under arbitrary stress paths is examined. The influences of rotation of the direction of principal stress axes and induced anisotropy are included in a rational way witho...
متن کاملForecasting ENSO with a smooth transition autoregressive model
This study examines the benefits of nonlinear time series modelling to improve forecast accuracy of the El Niño Southern Oscillation (ENSO) phenomenon. The paper adopts a smooth transition autoregressive (STAR) modelling framework to assess the potentially regime-dependent dynamics of sea surface temperature anomaly. The results reveal STAR-type nonlinearities in ENSO dynamics, resulting in sup...
متن کاملThe Extended Nuclear Matter Model with Smooth Transition Surface
The existence of electric fields close to their critical valueEc = m e c e~ has been proved for massive cores of 10 up to 10 nucleons using a proton distribution of constant density and a sharp step function at its boundary [1, 2, 3]. We explore the modifications of this effect by considering a smoother density profile with a proton distribution fulfilling a Woods–Saxon dependence. The occurren...
