Abstract: The paper uses a panel VAR framework to estimate the impact of a series of reforms aimed at reducing transactions cost and information cost in India’s secondary market for equity, on trading cost and trading volume. In particular, we focus on the reforms that were introduced after the creation of the National Stock Exchange (NSE) and screen-based trading that have been much discussed in the literature. Our results suggest that only the creation of the clearing corporation that reduced or eliminated counterparty risk had an economically meaningful/significant impact on trading cost and volume. We also find that the impact was much greater for mid-cap firms than for large-cap and small-cap firms. In the same vein, while trading costs and trading volumes Granger cause each other for mid-cap firms, there is only one-way causality for large-cap firms – trading cost Granger causes volume but the reverse is not true, and for small-cap firms there is no causal relationship between the two. Further, the impact of a shock to the trading cost on volume dissipates within 5 periods (months), as does the impact of a shock to the volume on trading costs. The implications of these findings are discussed in the paper.
