Abstract
The study examines the rupee–US dollar exchange rate (Rs/$) behaviour in the presence of increasing and ample capital inflows in the post-reform period in India. Using monthly data (1994:4 to 2007:8) the study estimates a basic exchange rate model in a time series framework in order to assess the relative significance of capital inflows in the presence of interest rate, inflation rate and growth rate differentials and other factors (forward exchange rate/expected exchange rate) in influencing the rupee–dollar exchange rate behaviour. It finds the dominance of foreign institutional investments affecting the rupee–dollar exchange rate and, to a certain extent, it is seen that the influence of the growth rate differential affects the exchange rate behaviour in India.

Notes
1The interest parity condition explains the relationship between interest rates and exchange rates. Under perfect capital mobility, interest rate differences must be offset by expectations of exchange rate movements if the investors are risk averse and endowed with rational expectations. The domestic interest rate can exceed the foreign interest rate only if the domestic currency is expected to depreciate. This is known as uncovered interest parity.
2In estimating the long-run parameters of the interest rate equations through Dynamic Ordinary Least Square (DOLS), it basically involves regressing any IEquation(1) variables on - other IEquation(1)
variables, any I(0) variables to be incorporated and leads and lags of the first differences of any IEquation(1)
variables in the model.
