Market structure implications of export-price uncertainty

This paper considers the profit-seeking firm that has the opportunity to export, as a price taker, to an uncertain rest-of-the-world market. When that firm competes domestically as an oligopolist the competitive export option can impact on both the firm and its domestic competitiors. The latter conjecture is explored and the resulting inferences are offered as a possible explanation for the market structures that tend to evolve in international markets.     

INTRADAY MARKET BEHAVIOR AND THE EXTENT OF FEEDBACK BETWEEN S&P 500 FUTURES PRICES AND THE S&P 500 INDEX

In this study we empirically examine the intraday lead/lag relation between S&P 500 futures prices and the S&P 500 index, and whether daily market characteristics are associated with changes in the relation. We estimate daily Geweke measures of feedback and regress time series of these measures on daily price volatility and volume characteristics. Results indicate that the contemporaneous price relation is substantive and that measures of contemporaneous feedback are positively associated with the daily range of the futures price. The primary implication is that the relation between cash and futures prices becomes stronger as futures price volatility increases. As volatility increases, information is being impounded at a faster rate so that futures and equity markets operate more closely as one market. Large futures price moves, by themselves, are not responsible for breakdowns in the stock-futures price relation.     

Unemployment or protectionism: Some choices for the USA and Western Europe to the year 2000

This article reports on the economic implications to the USA and Western European economies after imposing protectionist trade policies on selected groups of imports till 2000. The effects of this policy are also presented for Japan and the non-oil-producing developing countries. Before discussing the results of the computations and the import restricting assumptions, a summary of the methodological framework, the World Input-Output Model, used in the computation is presented.     

Revisiting the empirical estimation of the effect of margin changes on futures trading volume

This study revisits the empirical estimation of the effect of margin requirements on trading volume. Although theory suggests that margin requirements impose a cost to traders and will therefore likely reduce volume traded, empirical examinations have generally failed to find this association. The contention of this article is that the theory is correct, but empirical estimation has generally neglected to adjust margins for underlying price risk. After adjusting for risk, this analysis finds economically and statistically significant negative effects of margin requirements on trading volume as predicted by theory. This study examined 6 contracts over a 17‐year time period and found that financial futures contracts (gold, Dow Jones, and 10‐Year Treasury Notes) were considerably more sensitive to changes in margin requirements than agricultural futures (wheat, corn, and oats). © 2003 Wiley Periodicals, Inc.

Stock price crash risk and internal control weakness: presence vs. disclosure effect

This study examines the stock price crash risk for a sample of firms that disclosed internal control weaknesses (ICW) under Section 404 of the Sarbanes‐Oxley Act (SOX). We find that in the year prior to the initial disclosures, ICW firms are more crash‐prone than firms with effective internal controls. This positive relation is more pronounced when weakness problems are associated with a firm's financial reporting process. More importantly, we find that stock price crash risk reduces significantly after the disclosures of ICWs, despite the disclosure itself signalling bad news. The above results hold after controlling for various firm‐specific determinants of crash risk and ICWs. Using an ICW disclosure as a natural experiment, our study attempts to isolate the presence effect of undisclosed ICWs from the initial disclosure effect of internal control weakness on stock price crash risk. In so doing, we provide more direct evidence on the causal relation between the quality of financial reporting and stock price crash risk.     

Volume and Volatility Surrounding Quarterly Redesignation of the Lead S&P 500 Futures Contract

During the last weeks before each quarterly expiration of Standard & Poor's (S&P) 500 futures, the bulk of trading volume begins to shift away from the next‐to‐expire (nearby or lead) contract toward the second‐to‐expire (next out) contract. At some point, the exchange formally redesignates the next out as the new lead contract, and the next out replaces the nearby in the futures pit location designated for the lead contract. This event invariably results in a dramatic increase (decrease) in trading activity in the next out (nearby) contract. This shift in relative trading volumes is due to the microstructure of the futures exchange rather than new information or underlying volatility conditions. The event thus offers us an opportunity to examine how volatility responds to noninformation‐based exogenous changes in volume. This study examines the volatility behavior of nearby and next out S&P 500 futures contracts on the 10 days surrounding quarterly redesignation of the lead contract. Our model measures possible changes in (a) the level of volatility and/or (b) the association between volume and volatility after redesignation of the lead contract. Results indicate that when we account for the association between volume and volatility, the higher volume lead contract consistently experiences a lower level of volatility. This outcome supports the view that the larger population of liquidity providers who trade the more active lead contract fosters greater market depth and lower volatility. © 2001 John Wiley & Sons, Inc.
