Abstract
|
|
|
Purpose: The purpose of this study is to provide an empirical overview of the import patterns of the Eyeglasses and Contactlens industry.
Methods: This study used an Engle-Granger cointegration technique and Johansen’s multivariate cointegraion methodology test to check the stationarity of the model. This paper also applies Rolling regression to our model, indicating that Eyeglasses and Contact Lens import is endogenous to the economic variable.
Results: The empirical results show how the import in Eyeglasses and Contact Lens is related to the economic variables.
Conclusions: This paper shows how the import of Eyeglasses and Contactlens is influenced by economic variables, such as exchange rate and industrial product, and seasonal factors.
