摘要:In many countries, capital markets are often served by multiple stock
exchanges, typically with one national or dominant exchange and several
regional or satellite exchanges. While multiple exchanges create a competitive
landscape, they also lead to fragmented liquidity and diseconomies in
operations. This paper examines the role of the Lahore Stock Exchange (LSE)
in comparison with the country’s dominant exchange, the Karachi Stock
Exchange (KSE), in four areas: (i) market efficiency in processing information,
(ii) transaction costs, (iii) contribution to price discovery, and (iv) market
integration. A comparative analysis of the exchange performance indicates
the two exchanges to be at par in terms of informational efficiency and
transaction costs. There is evidence of informational linkages and
interdependencies between the two exchanges; the LSE appears to contribute
to price discovery and competes to an appreciable extent. Against the
background of proposals to merge the country’s three stock exchanges, a
major consideration in evaluating public policy is the relative performance of
the LSE and its viability as an effective competitor. Eliminating inter-
exchange competition by merging the stock exchanges is predicted to lead to
higher transaction costs, lower incentives for regulatory compliance, and
diminished motivation for promoting capital market development.
