Longevity and the life-cycle of management buy-outs

The longevity debate about buy-outs has hitherto been restricted. By focusing on large highly leveraged transactions, existing research has taken only a partial view of how long buy-outs last and the factors influencing longevity. This paper develops and tests hypotheses concerning the influences on buy-out longevity across the whole spectrum of management buy-out applications. Both quantitative and case study evidence from the U. K. is presented. A heterogeneity view of buy-outs is supported. Tests using quantitative data show that earlier exit is associated with larger buy-outs, and buy-outs arising on privatization from the public sector and from non-U. K. parents. Case study evidence principally supports hypotheses that earlier exit is associated with financing institutions being in a relatively stronger position than management and with more rapidly changing market conditions for the firm.     

An explanation of why shareholders' losses are so large after drug recalls

Recent studies show firms suffering drug recalls experience security losses many times larger than any reasonable measure of their direct cost. We discover that the implied standard deviation of stock returns from the Black-Scholes option pricing model significantly increases after a drug recall. The implied standard deviation provides a good proxy for the stock's ex ante beta. The higher systematic risk after a product recall must raise the discount rate used by investors. After a recall, stock prices are reduced in line with the lower expected future earnings and are further reduced because of a higher discount rate.     

Options and efficiency: Some experimental evidence

This paper examines the information aggregation role of options when agents possess diverse information about possible asset returns. We construct two identical experimental markets: one with and one without options. We find that options speed the information aggregation process. Asset markets that have parallel option markets aggregate traders' diverse information faster than markets where options trading is not available. Implied ranges were calculated from asset and option prices and compared to the actual ranges. These comparisons suggest that options may provide a means for agents to coordinate beliefs about asset values.     

The Economic Significance of User-Generated Feedback

This paper examines the impact of user-generated feedback on price at a price comparison site or shopbot. It employs a modified hedonic price function to explore the use made by current potential consumers of the experience of past actual consumers in evaluating quality attributes that were not observable when the product was initially launched on to the market. Using a database of daily observations on 211 digital cameras traded on NexTag.com, we find that the product’s star rating, reflecting all the available individual assessments of the product, has a significant negative impact on the discount on the manufacturer’s recommended selling price at which the product is offered.
