Investor confusion and similarly identified securities

This paper extends the analysis of Rashes (2001) to examine the co‐movement of prices for a sample of UK equity securities with similar ticker symbols and names. In contrast to Rashes (2001), we find only limited evidence of price changes that could be attributed to ticker symbol or name confusion. Our results suggest that any such confusion, if it exists at all, is most likely confined to very short time horizons and is not a systematic occurrence for similarly identified securities.     

Labour standards and capacity in global subcontracting chains: evidence from a construction MNC

This article investigates how fundamental labour rights specified in international framework agreements are implemented and monitored in subcontracting chains. It shows how labour's capacity for workplace‐based monitoring is influenced by factors such as ownership structures, the societal context, and, most importantly, the institutions and dynamics of local labour control.     

ON THE SIZE DISTRIBUTION OF WEALTH IN CANADA*

This paper is concerned with measurement of the size distribution of personal wealth in Canada. The only available estimates of this distribution are those provided on the occasions when Statistics Canada's Survey of Consumer Finance has surveyed assets and debts. Results of the latest “SCF” to do this, that of 1977, are not yet available. The paper shows that the previous study, conducted in 1970, indicated wealth-inequality as viewed by top quantile shares roughly of the same order as estimated by others for the U.S. and U.K. A comparison of asset and debt aggregates implied by the survey, however, with independent totals indicates that for almost all items the SCF likely under-estimated true holdings. The possible relative importance of sampling and non-sampling errors in explaining this distortion is considered, drawing on Monte Carlo evidence and American validation studies of survey response. It is concluded that sampling error is unlikely to provide the explanation for SCF discrepancies in aggregates, but that non-sampling error is capable of doing so. Finally the 1970 SCF distribution of wealth is re-estimated. First a correction is made for hypothetical differential response according to true net worth. Second an attempt is made to remove the effects of under-reporting by respondents. The “best-guess” re-estimated distribution exhibits mean net worth considerably greater than shown by the SCF but only a slightly greater degree of concentration. Under certain fundamental assumptions this result is surprisingly robust. The appropriate conclusion is not that survey estimates of the distribution of wealth are reliable, but that the strong non-sampling errors affecting the 1970 Canadian SCF wealth estimates may have been composed of almost completely offsetting sources of bias.     

Tacit collusion, firm asymmetries and numbers: Evidence from EC merger cases

This paper estimates the implicit model, especially the roles of size asymmetries and firm numbers, used by the European Commission to identify mergers with coordinated effects. This subset of cases offers an opportunity to shed empirical light on the conditions where a Competition Authority believes tacit collusion is most likely to arise. We find that, for the Commission, tacit collusion is a rare phenomenon, largely confined to markets of two, more or less symmetric, players. This is consistent with recent experimental literature, but contrasts with the facts on ‘hard-core’ collusion in which firm numbers and asymmetries are often much larger.     

Long‐term information,short‐lived securities

The authors explore strategic trade in short‐lived securities by agents who have private information that is potentially long‐term, but do not know how long their information will remain private. Trading short‐lived securities is profitable only if enough of the private information becomes public prior to contract expiration; otherwise the security will worthlessly expire. How this results in trading behavior fundamentally different from that observed in standard models of informed trading in equity is highlighted. Specifically, it is shown that informed speculators are more reluctant to trade shorter‐term securities too far in advance of when their information will necessarily be made public, and that existing positions in a shorter‐term security make future purchases more attractive. Because informed speculators prefer longer‐term securities, this can make trading shorter‐term contracts more attractive for liquidity traders. The conditions are characterized under which liquidity traders choose to incur extra costs to roll over short‐term positions rather than trade in distant contracts, providing an explanation for why most longer‐term derivative security markets have little liquidity and large bid‐ask spreads. © 2006 Wiley Periodicals, Inc.
