Return Volatility,Trading Imbalance and the Information Content of Volume

In this paper, we examine the relationship between volume and return volatility using the transaction data. We introduce transaction and volume imbalance measures to capture the information content of trades. These two information measures are shown to have a strong explanatory power for return volatility and contain incremental information about the asset values over and above that conveyed by the size and frequency of trades. Also, return volatility is significantly correlated with the percentage of trading volume taking place at NYSE. This result suggests that NYSE trades are more informative and contribute more to price discovery. There is evidence that price discovery concentrates in more heavily traded stocks, particularly the Dow Jones Stocks. Finally, return volatility is found to be persistent at the intraday level. The persistence level is higher for less frequently traded stocks. Return volatility also exhibits temporal variations. In particular, return volatility is significantly higher in the opening half-hour for less frequently traded stocks. Thus, stocks with different frequencies of trades may follow different volatility processes.     

Following the story: narrative mapping as a mobile method for tracking and interrogating spatial narratives

Museums and heritage tourism sites are highly curated places of memory work whose function is the assembling and ordering of space and narrative to contour visitors’ experiences of the past. Variations in such experiences within and between sites, however, necessitates a method that: (1) captures how guides, visitors, and exhibits interact within spaces when representing and performing history and (2) allows researchers to document those variations. We developed narrative mapping, a mobile and geographically sensitive form of participant observation, to enable museum scholars and professionals to systematically capture, visualize, and interpret tendencies and variations in the content, affective qualities, and spatial arrangements of museum narratives over multiple sites and across multiple tours at the same site. Two antebellum plantation museum case studies, Laura Plantation in Louisiana and Virginia’s Berkeley Plantation, demonstrate the method’s utility in documenting how stories are spatially configured and materially enlivened in order to analyze the ways enslaved persons are placed within these narratives.     

Delayed firm‐paid general training

This article adds the empirically verified, but analytically neglected, fact of delayed worker training to a model of general training. By delaying training, firms can gain partial information on worker‐firm matches, generating wage compression. Analytical results differ from those of other training models. In the noncooperative regime, all firm‐paid training is delayed, all worker‐paid training is immediate. With no externalities to other firms, the cooperative result is Pareto‐optimal. In a continuous‐time extension, firms choose a probationary period after which workers are trained. With longer probations, fewer bad‐match workers are trained and wage compression rises. Government training mandates are also studied.     

Underwriter Reputation and Initial Public Offers: The Detrimental Effects of Flippers

In this research, we examine the relationship between the reputation of investment banks and the investor clientele to whom they market initial public offers. We hypothesize that the most reputable investment banks have considerable distribution power but confine initial public offer sales to investors with long-term horizons in an effort to maintain prestige. Using the level of relative after-market trading volume to proxy for investor type, we find that as underwriter reputation increases investors with short-term trading horizons (“flippers”) tend to dominate the offerings over the lower prestige levels. For underwriters in the upper reputation tier, however, this dominance begins to decline with increasing reputation. In addition, we find a negative relation between the after-market price performance of the initial public offer firm and the first week's trading volume. The results suggest that flippers can be detrimental to the performance of initial public offer firms. While distributing power may be essential for the maintenance of the reputation of investment banks, the type of investor clientele also appears to be of major importance.     

The future for producers’ co-operatives

Drawing on a wider historical perspective and an in-depth case study, the authors seek to establish the status of the recent revival in worker co-operatives and the form that these organisations may take in the future.     

The role of market research for charities: Identifying target groups and developing successful relationships

No one can find friends by sitting at home, and no relationship can develop without plenty of interaction between the people involved. However, charities with large numbers of donors and volunteers cannot be expected to have day-to-day contact with more than a handful of their key supporters. This paper illustrates how market research can be used by charities as the conduit between charities and their supporters — not only to show how the relationship between the two sides can be developed to best effect, but also to identify the most appropriate target groups to find new support.
