Capital inflow simustaneusly influences exchange rate, and interest rate, and thus sequently affects stock prices. Employing cointegration approach and Engle Granger Error Corection Model (ECM), covering monthly time series data from January 2000 to April 2010, both short run and long run relationships are investigated. It is found out that there is cointegration relationship between stock price as dependent variable and  exchange rate  and interest rate, as independent variables. In the long run and in the short run, interest rate statisticaly significant negatively influences the stock prices. The impact of exchange rate on stock price is statistically significant, and changes in sign from negative in the short run effect to positive in the long run effect. In the long run, stock price is elastic to the changes in interest rate, and exchange rate.

Abstract

There are two purposes of this paper. Firstly, it deals with expectation formation. Secondly, it will be tested whether the expectation has a significant role in determining the current exchange rate in the case of Indonesian currency against the US dollar and Euro. This research will compare two kinds of expectation formation. Firstly, the expectation built from the fundamental economy is known as rational expectation formation. Secondly, the expectation formulated from past time series information, the Auto Regressive Moving Average (ARMA) model, is utilized. The steps to prove the role of expectation are stationary process, degree of integration, co-integration, and U-Theil's Inequality Coefficient Test (UTIC). It is found that both kinds of expectation formation have essential roles in determining the current exchange rate in Indonesia. However, according to UTIC criteria, a rational expectation better explains both current exchange rate movements.
