This paper investigates the order in which new information is first reflected in the market – through changes in spreads or through updated depths. We develop an error correction model of spreads and depths and estimate Gonzalo-Granger common factor components using two years of tick-by-tick...

Prior studies have reported a positive correlation between insider trading and stock price changes. The implication of these studies is that insider (i.e., informed) trades have a differential impact on price discovery than non-insider (i.e., uninformed) trades. Based on these results, various...

Using an audit trail transaction data set compiled by the Commodity Futures Trading Commission (CFTC), we seek to ascertain directly the motives behind dual traders’ own account trading and whether or not they are informed traders. We estimate our system of equations on each of the 101 most...

We address two important themes associated with institutions’ trading in foreign markets: (1) the choice of trading venues (between a company’s listing in its home market and that in the U.S. as an ADR); and (2) the comparison of trading costs across the two venues. To do so, we identify...

Using high-frequency data and a carefully constructed 1-1 matched sample of control (non-decimal) stocks, we isolate the effects of decimalization for a sample of NYSE-listed common stocks trading in decimals. We find that both quoted and effective bid-ask spreads and depths have declined...

We compare trading costs in the transparent U.S. Treasury bond market with the less transparent U.S. corporate and municipal bond markets, based on newly available transaction data. We estimate that the mean bid-ask spread per $100 par value is 23 cents for municipal bonds, 21 cents for...

We examine the determinants of the realized bid-ask spread in the U.S. corporate, municipal, and Treasury bond markets for the period 1995 to 1997, based on newly available transactions data. We find that the bid-ask spread is negatively related to a bond’s trading activity and positively...

Using proprietary audit trail transactions compiled by the Commodity Futures Trading Commission, we investigate, at the individual trader level, (1) the timing and (2) the determinants of dual traders’ personal trades. Our analysis reveals a surprising absence of any trade timing by dual...

Although brokers’ trading is endemic in securities markets, the form of this trading differs between markets. Whereas in some securities markets, brokers may trade with their customers in the same transaction (simultaneous dual trading or SDT), in other markets, brokers are only allowed to...

We compare trading costs in the U.S. Treasury bond market with U.S. corporate and municipal bond markets, based on newly available transaction data. We estimate that the mean bid-ask spread per $100 par value is 23 cents for municipal bonds, 21 cents for corporate bonds and 8 cents for Treasury...
