Testing for Linear and Nonlinear Granger Causality in the Stock Price-Volume Relation

Linear and nonlinear Granger causality tests are used to examine the dynamic relation between daily Dow Jones stock returns and percentage changes in New York Stock Exchange trading volume. We find evidence of significant bidirectional nonlinear causality between returns and volume. We also examine whether the nonlinear causality from volume to returns can be explained by volume serving as a proxy for information flow in the stochastic process generating stock return variance as suggested by Clark's (1973) latent common-factor model. After controlling for volatility persistence in returns, we continue to find evidence of nonlinear causality from volume to returns.     

Retailing from the margins - the re-emergence of a food co-operative movement?

The disadvantage faced by low-income food consumers has long been recognized, with such groups likely to pay more for their food products, which are commonly limited in terms of range and quality. Such disadvantage stems not only from economic constraints, but also from geographical, sociodemographic and infrastructural factors, such as low car ownership levels (which limit mobility), age, family structure and infirmity. Issues of access and mobility are especially pertinent given that the majority of U.K. food retailers have sought to achieve increased market share through the pursuit of economies of scale, the inherent benefit of high margin maintenance, large format development and the relocation to edge-of-town/out-of-town and affluent suburban sites. To date, little attention in the form of research has been directed to examining strategies adopted by those on low incomes to address such circumstances. This paper outlines the initial findings of a wider longitudinal study that examines the activities of food co-operatives and food groups within the Glasgow area, which are run by, and are for the benefit of, those on low incomes. Through semi-structured interviews with relevant local government departments and funding bodies, management committees and volunteers involved in the daily operation of food groups, the initial aim was to identify the operational and organizational characteristics of food cooperative initiatives. The next stage was to determine what those involved perceived as the contribution made to the members and wider community, and finally, future opportunities for food cooperatives were identified. The results therefore, provide an invaluable insight, not only into the workings of food co-operatives, but also into the experience of those on low incomes in respect of food shopping. The research findings, perhaps ironically, provide a possible strategic direction for food retailers who, in the face of traditional market saturation, must identify new market growth opportunities within areas that they have previously neglected.     

Relationship-Specific Assets and the Pricing of Underwriter Services

This paper investigates the effect of setup costs on the pricing of investment banking services. The existence of setup costs is predicted to result in lower underwriter spreads in IPOs for firms that are expected to issue again. Consistent with this prediction, I find significantly lower spreads for firms that make subsequent issues. I also find that a firm's likelihood of changing underwriters in a subsequent offer is related to the time between offerings and the underwriter's pricing performance in the IPO. These results suggest that the deviations from optimal IPO pricing carry a penalty for the underwriter.     

The Determinants of Stock Option Compensation: Evidence from Finland

A new, long, and rich panel data set consisting of all Finnish publicly traded firms is used to study how firm characteristics and stock market developments influence the adoption and targeting of stock option compensation. Stock option adoption is found to be a procyclical phenomenon. Findings from firm‐level econometric analysis often corroborate those based on U.S. data, but important differences also emerge. Findings include: (i) firms with higher market value per employee are more likely to use stock option compensation; (ii) share returns from the past year affect the adoption of targeted stock options, but not broad‐based plans; (iii) our results are consistent with the hypothesis that selective and broad‐based plans arise as solutions to differing monitoring difficulties. Broad‐based schemes are observed when production is human capital‐intensive and employee performance is hard to monitor, while selective schemes are adopted when ownership is dispersed and therefore owners may have weak incentives to monitor management.     

The Losses Realized in Bank Failures

This paper examines the losses realized in bank failures. Losses are measured as the difference between the book value of assets and the recovery value net of the direct expenses associated with the failure. I find the loss on assets is substantial, averaging 30 percent of the failed bank's assets. Direct expenses associated with bank closures average 10 percent of assets. An empirical analysis of the determinants of these losses reveals a significant difference in the value of assets retained by the FDIC and similar assets assumed by acquiring banks.     

LABOUR MARKET FLEXIBILITY AND EMPLOYMENT ADJUSTMENT: MICRO EVIDENCE FROM UK ESTABLISHMENTS

In this paper we study how firms react to demand shocks, examininghow different aspects of flexibility shape their responses.Our main findings are: (i) very few firms choose to adjust pricein response to a demand shock; (ii) firms with more flexibilityare more likely to respond to demand shocks by adjusting employmentand hours. Our results provide a microeconomic explanation forrecent macroeconomic evidence that labour input has become moreclosely aligned to the business cycle.     

A Nonlinear Factor Analysis of S&P 500 Index Option Returns

Growing evidence suggests that extraordinary average returns may be obtained by trading equity index options, and that at least part of this abnormal performance is attributable to volatility and jump risk premia. This paper asks whether such priced risk factors are alone sufficient to explain these average returns. To provide an answer in as general as possible a setting, I estimate a flexible class of nonlinear models using all S&P 500 Index futures options traded between 1986 and 2000. The results show that priced factors contribute to these expected returns but are insufficient to explain their magnitudes, particularly for short‐term out‐of‐the‐money puts.
