Bid-ask spreads in multiple dealer settings: Some experimental evidence
We report the results of an experiment designed to investigate the behavior of quoted spreads in multiple-dealer markets. We manipulate verbal communication (not allowed and allowed) and order preferencing (not allowed, allowed, and allowed with order-flow payment) between eighteen sessions. Without preferencing, spreads are wider when communication is allowed. With preferencing (and no order-flow payments), individuals do not have incentives to narrow the spread and a wide spread may be maintained without a collusive agreement. However, spreads narrow somewhat when individuals are given the ...

Immediate disclosure or secrecy? the release of information in experimental asset markets
The Federal Reserve has made significant changes in its predisposition to release information over time. This paper reports the results of experimental asset markets designed to investigate how the public disclosure of uncertain information affects market and individual outcomes. In one set of markets, no information is released at the beginning of each trading year. In two other sets, an imperfect pre-announcement of the state of nature is disclosed. The reliability of the pre-announcement (60 percent and 90 percent) varies across treatments. Halfway through each trading year, the state of ...

Asset prices and informed traders' abilities: evidence from experimental asset markets
This study reports the results of fifteen experimental asset markets designed to investigate the effects of forecasts on market prices, traders' abilities to assess asset value, and the link between the two. Across the fifteen markets, the authors investigate alternative forecast-generating processes. In some markets the process produces an unbiased estimate of asset value and in others a biased estimate. The processes generating the biased forecasts, though, are less variable than the process generating the unbiased forecast. The authors find that, in general, period-end asset price reflects ...

Competitiveness and price setting in dealer markets
The behavior of securities dealers has been closely scrutinized in the 1990s. Recent investigations of the National Association of Securities Dealers and the Nasdaq market by the U.S. Department of Justice and the Securities and Exchange Commission suggest that market makers colluded to fix prices and widen bid-ask spreads in attempts to increase dealers' profits at investors' expense. At a minimum, market makers appear to have adopted a quoting convention that can be viewed as anticompetitive behavior. ; This article explores the Nasdaq pricing controversy in light of economic theory and ...

Institutional investors, analyst following, and the January anomaly
Studies have documented that average stock returns for small, low-stock-price firms are higher in January than for the rest of the year. Two explanations have received a great deal of attention: the tax-loss selling hypothesis and the gamesmanship hypothesis. This paper documents that seasonality in returns is not a phenomenon observed only for small firms' stock or those with low prices. Strong seasonality in excess returns is reported for a sample of widely followed firms. Sample firms have unusually low excess returns in January, and returns adjust upward over the remainder of the year. ...

The origins of bubbles in laboratory asset markets
In twelve sessions conducted in a typical bubble-generating experimental environment, we design a pair of assets that can detect both irrationality and speculative behavior. The specific form of irrationality we investigate is probability judgment error associated with low-probability, high-payoff outcomes. Independently, we test for speculation by comparing prices of identically paying assets in multiperiod versus single-period markets. When these tests indicate the presence of probability judgment error and speculation, bubbles are more likely to occur. This finding suggests that both ...

Voluntary disclosure under imperfect competition: Experimental evidence
This study investigates disclosure behavior when a manager has incentives to influence the actions of a product market competitor in a Cournot duopoly. Theoretical research suggests that under various conditions the manager has incentives to withhold some signals and disclose others. Using an experimental economics method, we find support for partial information disclosure. Our results suggest that when the manager receives private information about industrywide cost, unfavorable (favorable) information is disclosed (withheld) and the competitor adjusts production accordingly. In contrast, ...

Time-varying volatility in Canadian and U.S. stock index and index futures markets: A multivariate analysis
We use a multivariate generalized autoregressive heteroskedasticity model (M-GARCH) to examine three stock indexes and their associated futures prices: the New York Stock Exchange Composite, Standard and Poor's 500, and Toronto 35. The North American context is significant because markets in Canada and the United States share similar structures and regulatory environments. Our model allows examination of dependence in volatility as it captures time variation in volatility and cross-market influences. Estimated time-variation in volatility is significant, and the volatilities are highly ...

Efficiency in index options markets and trading in stock baskets
Researchers have reported mispricing in index options markets. This study further examines the efficiency of the S&P 500 index options market by testing theoretical pricing relationships implied by no-arbitrage conditions. The effect of a traded stock basket, Standard and Poor's Depository Receipts (SPDRs), on the link between index and options markets is also examined. Pricing efficiency within options markets improves, and the evidence supports the hypothesis that a stock basket enhances the connection between markets. However, when transactions costs and short sales constraints are ...
