A new fluctuation test for constant variances with applications to finance

We present a test to determine whether variances of time series are constant over time. The test statistic is a suitably standardized maximum of cumulative first and second moments. We apply the test to time series of various assets and find that the test performs well in applications. Moreover, we propose a portfolio strategy based on our test which hedges against potential financial crises and show that it works in practice.     

Wealth and Poverty in the English Football League

Member clubs in professional sporting leagues can increase joint incomes by adopting measures that equalise playing performance. In the English Football League some degree of performance equalisation has traditionally been achieved by restricting financial competition and through income sharing arrangements. Elite clubs in the League have recently secured changes in these arrangements which will increase their dominance in the industry. This paper analyses the affects of these changes and of shifts in market demand on the recent financial positions and cash flows of ten of the most and ten of the least successful clubs, and concludes that collective management policies in the League are contrary to the normal economic objectives of a sporting league.     

Is investment decision-making influenced by perceptions relating to auditors’ client dependence and amount of audit fees?

The objectives of this study are to examine whether investing decisions are affected by knowledge about the auditor's revenue dependence on a client and whether the amount spent by a company on audit fees affects decisions to invest in the company. A behavioral experiment is conducted where risk assessments and investing decisions are made for four hypothetical investing scenarios. The study finds that investing decisions are affected by knowledge about an auditor's revenue dependence on a client, but are not affected by knowledge about the size of a client's audit fees.     

The Effects of Ambiguous Information on Initial and Subsequent IPO Returns

Newly public companies must disclose significant risk factors in the offering prospectus. These disclosures are examples of “soft” or ambiguous information. Ambiguity models predict that investors will alter their portfolio weights and react to subsequent signals about such information. We test for these effects in a sample of 1,398 initial public offerings (IPOs) using word count ratios between soft and hard information as measures of ambiguity. We find a significant relationship between the soft information on risk and both initial and ex post measures of returns. These results support the view that soft information embeds ambiguity and that it influences investors’ portfolio choices.     

Chinese consumer decision-making styles: A comparison between the coastal and inland regions

China is rapidly becoming an important market for consumer goods, but relatively little is known about variations in consumer shopping patterns in different regions of China. We employ a cultural materialism perspective in understanding decision-making styles of inland and coastal shoppers. Our findings reveal that consumers in the two regional markets do not differ in utilitarian shopping styles but they do in hedonic shopping styles. Marketers need to understand these differences to be able to market effectively to consumers in different regional markets within China.     

Who is the “Self” that Buys?: An Exploratory Examination of Imaginative Consumption and Explanation of Opinion Leadership

The present research, first, combines literatures on self‐theory, imaginative consumption, and opinion leadership. Second, the research, using self‐theory, explores individual difference variables predictive of imaginative consumption in two studies using different populations. The results reveal fashion product involvement, self‐esteem, fashion knowledge, idea shopping motivation, and probability of a mispurchase influence the degree to which an individual imaginatively consumes fashion products. Third, the research makes a contribution by explaining from where opinion leaders derive their abilities—imaginative consumption. In contributing to scholarly work, the research explains the role of imagination and opinion leadership in both theories of self‐verification and self‐enhancement. Managerial implications include identifying potential opportunities for marketing communications and retail management. The findings are promising and encourage further exploration of the phenomenon of imaginative consumption.     

UNDERSTANDING THE FINANCIAL CONSEQUENCES OF THE BULLWHIP EFFECT IN A MULTI‐ECHELON SUPPLY CHAIN

This article is concerned with how supply chain strategies can mitigate the Bullwhip Effect and inflated inventories from the perspective of the central firm (typically a manufacturer) in the supply chain. We first outline a base case scenario with a validated system dynamics simulation model, using supply chain characteristics as reported by a real firm, in this case a Mexican electronics supplier to U.S. automobile assemblers. We find, surprisingly, that a lower Bullwhip Effect Index (BE) does not always lead to lower costs in the supply chain studied. Furthermore, sensitivity analysis suggests some interesting, counterintuitive results. The implications of these findings are further developed as we test how lead time reduction can also reduce the Bullwhip Effect in the simulated setting.     

Applying financial portfolio and multiple criteria approaches to product line decisions

This article describes the application of decision rules from financial portfolio theory to the evaluation of product lines. The focus is on the risk/return implications of an “add” decision to the total portfolio versus the individual product. Multiple criteria approaches that aid product line evaluations are also presented.
