Estimating the price elasticity of demand in the London stock market

The hypothesis that demand curves for individual stocks slope downwards is typically investigated by empirical analysis of stock price movements following events that cause shifts in demand or supply. However, it is difficult to attribute observed price movements between downward sloping demand curves and information conveyed by the event. In this paper an econometric approach, based on market-maker response to unexpected changes in inventory, is used to separate out the slope of the demand curve from information effects and estimate the slopes of the demand curves for twenty stocks included in the Financial Times-Stock Exchange 100 Share Index (FTSE100). The analysis suggests that downward sloping demand curves would decrease the price by about 7.5% for a 1% increase in the number of outstanding shares.     

Day-of-the-Week Autocorrelations, Cross-Autocorrelations, and the Weekend Phenomenon

This study examines whether autocorrelations or cross-autocorrelations are more closely associated with the weekend phenomenon. Our results show a significant day-of-the-week pattern in autocorrelations associated with the weekend phenomenon. However, we find no marginal influence of a day-of-the-week pattern in cross-autocorrelations on the weekend phenomenon.     

Differences in the Cost of Mortgage Credit Implications for Discrimination

This paper estimates the mortgage interest rate differences paid by Asian, Hispanic, and African–American borrowers to a national home mortgage lender in the years 1988–1989. Controlling for differences in market rates, rate lock protection, and borrower risk factors, conventional loan interest rates are almost perfectly race-neutral. The single deviation from race-neutrality is that when interest rates fall during the borrower's rate-lock period, only African–American borrowers are unable to capture a share of this decline. Government (FHA and VA) credit models show small premia paid by African–American borrowers of about $1.80 per month on average. In government lending, Hispanic borrowers alone are unable to capture rate declines occurring during the borrower's rate-lock period.     

Negotiations under the threat of an auction

Many takeovers occur after one-on-one negotiations, which suggests a troubling lack of competition. We seek to determine whether acquirers in such friendly deals are truly insulated from competitive pressures. We study two countervailing influences: (1) potential but unobserved latent competition, i.e., the likelihood that rival bidders could appear, and (2) anticipated auction costs when negotiations fail. Using various proxies, we find that latent competition increases the bid premium offered in negotiated deals and that auction costs reduce the premium.     

Accounting for Foucault

Michel Foucault's concept of governmentality has been central to critical accounting research for two decades, a centrality that has placed systems of calculation as the starting point of discussions of the state, the firm and the market. We begin by outlining the development of governmentality in Foucault's own work. Despite the rich, productive nature of the concept, Foucault was careful to define governmentality as broadly and loosely as possible, the better to convey its open-endedness. The second section considers the introduction of Foucault to accounting research. The combination of Foucault and accounting history is not at all obvious, but became possible because a series of important contextual studies demonstrated that accounting history had to consider both the historicity of the profession and that its practices were vital in constructing measures of organisational performance, not simply uncovering previously obscure or hidden social realities. Moreover, accounting history studies the production of targets and measures of progress towards utility and welfare, processes that are not reducible to the firm or even to economic calculation. Our third section outlines the genesis of the ‘London School of governmentality’ and the main strands of their theoretical contribution. Finally, we examine the governmentalists’ analysis of corporate restructuring and the introduction of new production organisation by Caterpillar. Our aim is to use the Caterpillar case as the vehicle for a broader consideration of governmentality, strategy and the enterprise.     

The Effect of Policyholder Transfer Behavior on the Value of Guaranteed Minimum Death Benefits

Abstract

Variable annuity contracts frequently include both guaranteed minimum death benefit (GMDB) options and options to transfer funds between fixed and variable accounts. We model the difference between fixed and variable rates as the primary determinant of policyholder transfer behavior. We find that people tend to transfer their money into variable accounts at about 39% of the rate that would be required to maintain constant percentage rebalancing, but with the opposite sign. If these transfers are not taken into account, the GMDB options on the variable accounts will be overvalued and overhedged. Ignoring this effect can have a substantial impact on the size of the futures portfolio needed to hedge this risk and a nonnegligible impact on the earnings of the variable annuity portfolio.     

The Variance Gamma Process and Option Pricing

A three parameter stochastic process, termed the variance gamma process, that generalizes Brownian motion is developed as a model for the dynamics of log stock prices. The process is obtained by evaluating Brownian motion with drift at a random time given by a gamma process. The two additional parameters are the drift of the Brownian motion and the volatility of the time change. These additional parameters provide control over the skewness and kurtosis of the return distribution. Closed forms are obtained for the return density and the prices of European options. The statistical and risk neutral densities are estimated for data on the S & P500 Index and the prices of options on this Index. It is observed that the statistical density is symmetric with some kurtosis, while the risk neutral density is negatively skewed with a larger kurtosis. The additional parameters also correct for pricing biases of the Black Scholes model that is a parametric special case of the option pricing model developed here.

Handling Missing Data by Re-approaching Non-respondents

When handling missing data, a researcher should be aware of the mechanism underlying the missingness. In the presence of non-randomly missing data, a model of the missing data mechanism should be included in the analyses to prevent the analyses based on the data from becoming biased. Modeling the missing data mechanism, however, is a difficult task. One way in which knowledge about the missing data mechanism may be obtained is by collecting additional data from non-respondents. In this paper the method of re-approaching respondents who did not answer all questions of a questionnaire is described. New answers were obtained from a sample of these non-respondents and the reason(s) for skipping questions was (were) probed for. The additional data resulted in a larger sample and was used to investigate the differences between respondents and non-respondents, whereas probing for the causes of missingness resulted in more knowledge about the nature of the missing data patterns.     

Capitalization and the Voucher: An Analysis of Precinct Returns from California's Proposition 174

In 1993, Californians voted on a school voucher initiative. We hypothesize that homeowners in good school districts understood the voucher to be a threat to their property values and thus voted against it. Precinct returns from Los Angeles County confirm this hypothesis. We also examine an alternative hypothesis explaining the relationship between school quality and precinct returns. According to the alternative, voters perceived the initiative to be a referendum on public school quality. To distinguish between the two hypotheses, we compare the voting patterns of homeowners and renters. The comparison does not favor one hypothesis over the other.
