In order to describe the comovements in both conditional mean and conditional variance of high dimensional nonstationary time series by dimension reduction, we introduce the conditional heteroscedasticity with factor structure to the error correction model. The new model is called the error correction–volatility factor model. Some specification and estimation approaches are developed. In partic...

This paper investigates the lag length selection problem of a Vector Error Correction Model (VECM) by using a convergent information criterion and tools based on the Box-Pierce methodology recently proposed in the literature. The performances of these approaches for selecting of the optimal lag length are compared via Monte Carlo experiments. The effects of misspecified deterministic trend or c...

The present paper analyzes the existence of a long-run relationship between the trade balance and exchange rate of Iran and South Korea by a new approach. It proposes an asymmetric co-integrating NARDL model by two positive and negative partial sum decompositions which can use mixed I (0) and I (1) variables by bounds testing approach. The proposed tests are based on calculated F –statistics an...

the law of one price (lop) in oilseeds market of iran (cotton, maize, and soybeans) is tested in the present study, using annual domestic data, and world prices for the period of 1992-2008. modern time series econometric analysis methods, including co-integration and error correction model are made use of. the main results obtained from the study confirms an in the long- run relationship betwee...

Background & objectives: Despite the importance and impact of health and education on economic growth in countries, the causal relationship between education and health is important to policymaking. This study aimed to investigate the causality relationship between education and health in the short and long runs using the Vector Error Correction Model (VECM) in Iran. Method: This was an analyt...

This study investigated the dynamic relationship between money, prices and output in a multivariate structure of casualty analysis in Iran for the two period of 1969 to 2012 (entire period) and 1989 to 2012 (sub-period). This statistical framework has been projected for situations where causal links may have changed over the sample period. Results of a three-variable Vector Error Correction Mod...

In this article, we estimate the vertical price transmission through the Iranian rice marketing chain by usingmonthly data from March 2000 to February, 2009 and error correction model (ECM).The causality testresults indicate that changes in the producer price clearly led changes in wholesale and retail prices. InProducer-Retail and Wholesale-Retail models, price transmission is asymmetric but i...
