This paper examines the effect of temporarily suspending the trading of exchange-listed individual stocks. We evaluate whether regulatory authorities can successfully use the mechanism of trading suspension in forcing companies to disclose new and material information to the capital market. Previous studies on trading suspensions mainly concentrate on North-American stock markets and find no co...

A gravity model, frequently used to explain trade patterns, is used to explain stock market correlations. The main result of the trade literature is that geography matters for goods markets. Physical location and trading costs should be less of an issue in asset markets. However we find that geographical variables still matter when examining equity market linkages. In particular, the number of ...

We examine the optimal trading strategy for an investment fund which in the absence of transactions costs would like to maintain assets in exogenously fixed proportions, e.g. 60/30/10 in stocks, bonds and cash. Transactions costs are assumed to be proportional, but may differ with buying and selling, and may include a (positive) capital gains tax component. We show that the optimal policy invol...

This paper studies the relation between the premiums in takeover bids involving exchange-listed target firms from 1975-91 and the pre-announcement stock price runups. The evidence shows that the pre-bid runup and the postannouncement increase in the target’s stock price (the Amarkup@) are generally uncorrelated. With little substitution between the runup and the markup, the runup is an added co...

We analyze determinants dealers' market shares and trading costs. find dealer have lower price impacts than exchange trades, consistent with uninformed traders seeking dealers. Due to ability avoid informed investors, dealers often undercut...

We use computer-based simulations of stock market as a background environment for experimental tests of the integration of an order-driven trading system into a dealedquote-driven market. Experimental subjects traded using a traditional dealer quote screen (such as Nasdaq in the U.S. or the London Stock Exchange's SEAQ), to which was added a public limit order facility. Data captured on subject...

This article investigates the impact of terrorist attacks on global capital markets. We find economic consequences of terrorist attacks spillover through trading partners. When a bigger economy (measured by GDP) is targeted, the spillover is specifically prominent for economically smaller trading partners. Such partners see a -2.5% reduction in national stock indices. Odds for smaller trading p...
