Abstract: This paper investigates the time-varying return and volatility spillover impact of exchange rates, interest rates, consumer prices, and industrial production on stock market returns in Pakistan by using monthly data covering the time period 2000-2018. For this purpose, we first estimate GARCH models to obtain the conditional variance. Next, we employ the Gaussian state-space model, which allows the coefficients to vary over time, to estimate the time-varying return and volatility spillover impacts of the underlying variables on stock market returns. We find a significant time-varying impact of inflation rate, interest rates, and exchange rates on stock returns, suggesting that the impacts of these variables on stock returns change over time. The findings also confirm the time-varying volatility impacts, indicating that the intensity and magnitude of the transmission of macroeconomic volatility to stock returns’ volatility significantly changes over time. This empirical analysis is helpful for investors and firm managers to design and implement more effective hedging strategies to minimize interest rate, consumer price, and exchange rate risks.
