Abstract
We analyse asymmetric interest rate pass through, the impact of interest rate volatility on interest rates and the monetary transmission mechanism in the countries of the CSME22Caribbean Single Market and Economy. using the Asymmetric TAR and MTAR cointegration models by Enders and Siklos (2001) and the EC-EGARCH(1, 1)-M model by Wang and Lee (2009), who examined the same issue for the US and nine Asian countries. The CSME is a unique case of study given that it contains within it a monetary union: the OECS2. First, our results show that there is complete pass through in the retail lending rate for Trinidad and Tobago and for St. Lucia and therefore, by extension, in all the countries of the OECS33Organization of Eastern Caribbean States. but not the other countries of the CSME. In contrast, Wang and Lee (2009) found complete pass through for the US deposit rate but not in the rates of the other nine Asian countries. Second, in Wang and Lee (2009) the results of the TAR and MTAR models show asymmetric cointegrating relationships in the lending rate of three Asian countries and the deposit rate of five Asian countries. Comparatively, our results show asymmetric cointegrating relationship in the lending and deposit rate of only three countries out of six: Jamaica, Guyana and St. Lucia. Third, the results from the conditional mean equation in the EC-EGARCH(1, 1)-M model in Wang and Lee (2009) show that for the countries with asymmetric cointegrating relationships, the lending rate displays downward adjustment rigidity and the deposit rate displays upward adjustment rigidity. In contrast, our results show that both rates for Jamaica display upward adjustment rigidity and both rates for Guyana and St. Lucia display downward adjustment rigidity. Finally, similarly to Wang and Lee (2009), our results from the EC-EGARCH(1, 1)-M models show that the effect of interest rate volatility on interest rates varies among countries. Three out of the Asian countries from Wang and Lee (2009) support the collusive pricing arrangement hypothesis while in our case it happens only in two countries out of six from the CSME: Guyana and St. Lucia. Moreover, the leverage effect exists in the lending rate for two out six countries in the CSME as it happens in Wang and Lee (2009) in two out of their Asian countries. Along the same lines, the leverage effect exists in the deposit rate of three countries in the CSME, contrary to Wang and Lee (2009), who do not find any evidence at all. This shows evidence of an important heterogeneity in the behaviour of the CSME countries and that Trinidad and Tobago and St. Lucia (showing the effect of belonging to a monetary union) are our only analysed countries where, as in the US, there is complete pass through and the central bank can transfer all the cost associated with an increase in its policy rate to the retail rates.....
