چکیده

This paper is concerned with the power of tests for regime switching. Asymptotic results are currently available only for the null distribution, and this distribution is dependent on the underlying parameter space. This paper addresses the lack of asymptotic results. The asymptotic behavior of the test statistic is determined under a full range of drifting sequences of true distributions. The results are based on a construction of the test statistic in terms of Hermite polynomials. The number of terms in the polynomial construction depends on the size of the parameter space. Using this relation, a collection of power curves, indexed by the sample space, is obtained. The …nite sample properties of the test statistic are analyzed via Monte Carlo simulation.

Misalignment on the Persistence of Inflation in Iran

The purpose of this study is to investigate the impact of exchange rate misalignment on inflation persistence. For this purpose, Vector Auto Regression method and Markov Switching model is used for quarterly data during 1989:4 -2014:3. The results show that, the impact of liquidity growth and exchange rate misalignment on inflation persistence is positive. On the other hand, GDP growth has a ne...

Estimating Stock Price in Energy Market Including Oil, Gas, and Coal: The Comparison of Linear and Non-Linear Two-State Markov Regime Switching Models

A common method to study the dynamic behavior of macroeconomic variables is using linear time series models; however, they are unable to explain nonlinear behavior of the series. Given the dependency between stock market and derivatives, the behavior of the underlying asset price can be modeled using Markov switching process properties and the economic regime significance. In this paper, a two-...

Forecasting Crude Oil prices Volatility and Value at Risk: Single and Switching Regime GARCH Models

Forecasting crude oil price volatility is an important issues in risk management. The historical course of oil price volatility indicates the existence of a cluster pattern. Therefore, GARCH models are used to model and more accurately predict oil price fluctuations. The purpose of this study is to identify the best GARCH model with the best performance in different time horizons. To achieve th...

Modeling Gasoline Consumption Behaviors in Iran Based on Long Memory and Regime Change

In this study, for the first time, we model gasoline consumption behavior in Iran using the long-term memory model of the autoregressive fractionally integrated moving average and non-linear Markov-Switching regime change model. Initially, the long-term memory feature of the ARFIMA model is investigated using the data from 1927 to 2017. The results indicate that the time series studied has a lo...

Has Tehran Stock Market Calmed Down after Global Financial Crisis?Markov Switching GARCH Approach

We have introduced an early warning system for volatility regimes regarding Tehran Stock Exchange using Markov Switching GARCH approach. We have examined whether Tehran Stock Market has calmed down or more specifically, whether the surge in volatility during 2007-2010 global financial crises still affects stock return volatility in Iran.  Doing so, we have used a regime switching GARCH model.  ...
