University research and development of a microsatellite

Developing a microsatellite at a university is an effective means of training engineering students for an R&D career. Such a programme requires the adoption of many research and development processes from industry. This paper describes how tailored forms of systems engineering, project management and technology management were applied to develop a high technology product at a tertiary educational institution. This microsatellite development programme has produced students who are well prepared for the realities of engineering practice, and a research and development facility that earns research funding for the university.     

Takeovers and cooperatives: governance and stability in non-corporate firms

If consumers wholly or partially control a firm with market power they will charge less than the profit maximizing price. Starting at the usual monopoly price, a small price reduction will have a second order effect on profits but a first order effect on consumer surplus. Despite this desirable static result, it has been argued that cooperatives are vulnerable to take-over by outsiders who will run them as for-profit businesses. This paper studies takeovers of cooperatives. We argue that there will not be excessive takeovers of cooperatives due to the Grossman-Hart problem of free riding during takeovers.     

Variable reduction,sample selection bias and bank retail credit scoring

This paper investigates the effect of including the customer loan approval process to the estimation of loan performance and explores the influence of sample selection bias in predicting the probability of default. The bootstrap variable reduction technique is applied to reduce the variable dimension for a large data-set drawn from a major UK retail bank. The results show a statistically significant correlation between the loan approval and performance processes. We further demonstrate an economically significant improvement in forecasting performance when taking into account sample selection bias. We conclude that financial institutions can obtain benefits by correcting for sample selection bias in their credit scoring models.     

The Marketers’ Prismatic Palette: A Review of Color Research and Future Directions

Color carries meaning and can influence consumers’ thoughts, feelings, and behaviors. Many disciplines, such as neuroscience, psychophysics, visual cognition, and biology have used new technologies to gain insights in understanding the complexities of color perception, yet there exists relatively little research in the field of marketing. This paper aims to reestablish the importance of color research in marketing, draw attention to the complex nature of this research, and to fuel further investigation and the development of new insights about color as it relates to marketing. The authors offer an integrated conceptual framework centered on the embodied and referential meanings of color and highlight the complexities and nuances that researchers must consider in order to develop this area. Insights from and gaps in the extant literature are highlighted to present a set of questions and propositions for future research in this area of investigation.     

The multinomial option pricing model and its Brownian and Poisson limits

The Cox, Ross, and Rubinstein binomial model is generalizedto the multinomial case. Limits are investigated and shown toyield the Black-Scholes formula in the case of continuous samplepaths for a wide variety of complete market structures. In thediscontinuous case of Merton-type formula is shown to result,provided jump probabilities are replaced by their correspondingArrow-Debreu prices.     

The role of low expectations in health and education investment and hazardous consumption

Abstract .  Young people with little 'social or health capital' may be more likely to take up hazardous consumption and shun investments in human capital, raising their likelihood of a 'rags to rags' sequence. First, diminishing marginal utility could raise the marginal benefit of hazardous consumption and the cost of investment. But poor youths may also have lower expectations of future success, independent of the choices they make. Lower expectations of success could reduce the future cost of hazardous consumption and benefit of investment. We test the effect of expectations on decisions to smoke, drink hazardously, exercise, and complete high school, using a longitudinal study of youth in New Zealand. We find that 15-year-olds' expectations of success predict the subsequent onset of smoking, lack of exercise, and failure to complete high school, but not hazardous drinking. While some of the influence of expectations can be explained by low social and health capital, IQ, and other factors, expectations retain a direct effect on smoking and exercise once these other factors are controlled for.     

HOUSE PRICES AND THE ECONOMY

UK house prices more than doubled from 1985 until 1989, with house price inflation over the previous year peaking at 34 per cent in the fourth quarter of 1988. The ratio of house prices to average incomes reached levels which surpassed even those experienced during the 1972-73 house price boom. This sharp increase in housing wealth has been a major factor in the fall in the savings ratio over the past three years. This forecast release examines the prospects for future house price movements, discusses the sources of the recent house price boom and finally considers the possible impact on consumer expenditure.     

Option Pricing With V. G. Martingale Components1

European call options are priced when the uncertainty driving the stock price follows the V. G. stochastic process (Madan and Seneta 1990). the incomplete markets equilibrium change of measure is approximated and identified using the log return mean, variance, and kurtosis. an exact equilibrium interpretation is also provided, allowing inference about relative risk aversion coefficients from option prices. Relative to Black-Scholes, V. G. option values are higher, particularly so for out of the money options with long maturity on stocks with high means, low variances, and high kurtosis.
