in this paper asymmetric price transmission mechanism and nonlinear adjustment between producer and retail prices of milk were examined in zanjan province of iran. for this purpose, a two-regime threshold vector error correction model (tvecm) and a sup-lm test developed by hansen and seo (2002) were employed for checking presence of a threshold effect. application of unit root tests indicated t...

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...

among the food products, grains play an important role in the consumption patterns of people, especially in the developing countries. since iran's main source of public dietary energy comes directly from grains, investigating and identifying the determinants of import of these products can be an important step towards food security. most experimental studies consider import of grains as only a ...

This paper uses the semiparametric error correction model (Li andWooldridge, 2002) and investigates the dynamics of wage, employment and labor efficiency after introducing five-day work week to the Korean labor market. Efficient working hour function is obtained by nonparametric method (polynomial approximation) and the dynamics are investigated using impulse response analysis. Average derivati...

The imbalances between investment financing and domestic savings in terms of providing sufficient capital are an obstacle to implementing economic development Indonesia. Therefore, the flow foreign is indispensable, one which by portfolio order increase market liquidity as a source development. This study aims analyze response influence gross product variables, inflation, exchange rates, intere...

We consider structural vector error correction models (VECMs) in which permanent shocks are partially identified with a set of long-run restrictions, and fully identified with an additional set of short-run restrictions. An identification method with a combination of short-run and long-run restrictions has been studied in the vector autoregressive models literature, but not thoroughly applied t...

This paper discusses the money demand function in China. We use Cointegration technique and Error Correction Model to estimate the long-run and short -run money demand function. We find that M2 aggregate appears to be cointegrated with price level and income. We also specified a satisfying error correction model for M2.

This study aimed to discover the insight of error correction by implementing two correction systems on three Iranian university students. The three students were invited to write four in-class essays throughout the semester, in which their verb errors and individual-selected errors were corrected using the Code Correction System and the Individual Correction System. At the end of the study, the...

Non linear error correction models (NLECM) have been increasingly used recently in the econometric literature since they lead to more insightful results than the linear models in empirical studies. In this research we present alternative methods of dealing with non linearity in error correction models. We apply these models to the demand for money in Tunisia and our results show that we get bet...
