However, there has been a lot of controversy over the direction of the casual relationship between the service quality and the customer satisfaction. The purpose of this study is to investigate the casual relationship between the service quality and the customer satisfaction. Granger's test of casuality method has been used to test the casuality relationship between two variables. In this paper, we applied the Granger's test of casuality method to KS-SQI and NCSI data of 17 business area which had been gathered annually.

This study tests for the law of one price and Grander Causality between the EU ETS and Nord Pool $CO_2$ allowance prices. The Johansen cointegration test shows that there exists a long run equilibrium between EU ETS and Nord Pool prices and support the law of one price. The Granger casuality test suggests that the EU ETS leads Nord Pool for all vintages traded. The test results imply that the EU ETS can be regarded as the representative carbon market in the EU where many exchanges just started competing for the newly rising market for carbon.

Comovement of international stock market prices has been lately a major controversy in the global stock market. This paper explores whether the common trend has really existed among the US, Japan and Korea's stock markets using the econometric techniques such as VAR, VECM as applied. Pair of indices from the exchange market and the over-the-counter market in each country has been tested, and the exchange market only has been turned out that the common trend existed. The dynamic analyses using the Granger causality test, impulse response function, and the forecast error decomposition have followed to show that the US stock market has played some important role in the Korea and Japan's market in the exchange as well as in the OTC market. The results of the paper imply that the more careful investigation with respect to the co-integration may be necessary in the global market integration studies.
