We estimate expected short interest for Nasdaq stocks. Extending prior work, our research is among the first to investigate
the impact of ownership structure on short-selling activity. We find that short interest is negatively related to institutional
ownership and positively related to inside ownership; stocks with greater liquidity and smaller relative spreads are more
heavily shorted. We also develop a measure of the unanticipated level of short selling; relative to the reported amount of
short interest, this unexpected level of short selling seems at first to better represent the opinions of informed investors
engaging in costly short-selling activities. However, the power of the unanticipated level of short-selling factor is displaced
when we make allowances for traditional market, firm-size, and momentum variables. 相似文献

The year of 1994 was a milestone on a historical road of the textile trade development worldwide. The Final Act concluding the Uruguay Round and officially establishing the WTO regime was signed during ministerial meeting at Marrakesh, Morroco on the 15th of April, 1994, and hence is known as the Marrakesh Agreement. That marked a beginning of quota phase out. China has been on a resolute stance to trade restrictions and protectionism all through quota phase out and post-quota period and will continue to do so when safeguard deal terminates… 相似文献

We investigate determinants of foreign ownership in newly privatized firms. We analyze data on privatized Czech firms to address two related general questions. First, what characteristics distinguish transition firms that attract a foreign investor? Second, how do firm‐specific characteristics influence the size of the foreign equity stake? Our results suggest that foreign investors i) seek safe, profitable firms in which they can exert unchallenged influence on corporate governance and then ii) structure their equity stakes to mitigate agency costs and political risk. 相似文献

This paper offers insights into developments in the practice of performance measurement and management through examination of three case studies. Analysis of the cases suggests a clear distinction between performance measurement and management. It clarifies the usefulness of implementing broad-based performance measurement frameworks, and the criticality of organisational culture to effective performance management. 相似文献

We use simulation methods to examine the results of hedging maize food security imports into Malawi and Zambia on the South African Exchange (SAFEX). Results show that hedging using either futures or options can spread import costs over time, thereby reducing variability, and also possibly generating lower average costs. These benefits are increased if hedging only takes place when local prices are at less than import parity and also if the hedge is levered. However, problems will remain so long as intra-regional transport costs remain high. 相似文献

Abstract: We consider the impact of the May 1999 move to screen trading of the LIFFE FTSE 100 index futures contract. This resulted in a narrowing of the effective spread. Spread determinants are broadly similar in the two regimes. The narrowing of the spread appears due to increased competition among traders and a decline in tick-level volatility rather than to the way these or other variables affect the spread. Market depth appears largely unaffected. Under screen trading, realized spreads widen as more limit orders are taken up rather than in relation to order size per se . 相似文献

Using a hedonic pricing model, this paper investigates the responsiveness of residential property values in a well-defined
inner-city neighborhood of Kenosha, Wisconsin, to the presence of two small former industrial sites contaminated by various
environmental pollutants, or brownfields, and a local neighborhood park, or greenspace. Using readily available data on sales
and assessments for residential property in close proximity to the brownfields and the greenspace, we estimate well-behaved
and statistically significant property value gradients with respect to the park, the environmental amenity, and the brownfields,
the environmental disamenities. These functions are then used to estimate the possible impact that brownfield remediation
may have on total property value. We estimate that remediation and redevelopment of the brownfields into greenspaces would
increase property values for the 890 neighborhood residences between $2.40 and $7.01 million. These results suggest that small
brownfields have a measurable impact on property values and that readily accessible data can be used to help local policymakers
make decisions on remediation issues. 相似文献

Learning, price formation and the early season bias in the NBA 总被引:1,自引:0,他引:1

We test the NBA betting market for efficiency and find that totals lines are significantly biased early each season, yet sides lines do not show a similar bias. While market participants generally force line movements in the correct direction from open to close, they do not fully remove the identified bias in totals lines. This inefficiency enables a profitable technical trading strategy, as the resulting win rate of our proposed simple betting strategy against the closing totals line is 56.72%. 相似文献
