Measuring the systemic risk transfer from the United States to the South African financial sector

The sub-prime crisis in 2008 illustrated how systemic risk in the financial sector of one country could spread to the financial sectors in other countries, and subsequently result in a global financial crisis. This direct transfer of systemic risk was made possible by phenomena such as contagion and common shocks. The way in which these elements of interconnectedness can magnify seemingly small levels of systemic risk, and subsequently transfer between financial sectors illustrate the necessity for a more in-depth analysis. This measurement is done using three approaches. A dynamic conditional correlation (DCC) model is used to investigate contagion. To analyse the volatility spillover effect from the US to SA, an exponential generalized autoregressive conditional heteroskedastic (EGARCH) model is employed. Finally, a new contribution is made where a marginal expected shortfall (MES) model is used to set the FTSE/JSE All-Share Index (ALSI) as a hypothetical bank in the financial sector of the S&P 500. All approaches show weak evidence for a direct systemic risk transfer and therefore indicate that any systemic risk transfer is more likely to take an indirect form through changes in capital flows or interest rates.     

Exploring the ethicality of firing employees who blog

This exploratory study evaluates the ethical considerations related to employees fired for their blogging activities. Specifically, subject evaluations of two employee‐related blogging scenarios were investigated with established ethical reasoning and moral intensity scales, and a measure of corporate ethical values was included to assess perceptions of organizational ethics. The first scenario involved an employee who was fired because of innocuous blogging, while the second vignette involved an employee who was fired because of work‐related blogging. Survey data were collected from employed college students and working practitioners. The findings indicated that the subjects' ethical judgments that firing an employee for blogging was unethical were negatively related to unethical intentions to fire an employee for blogging. Moral intensity was positively related to ethical judgments and negatively related to unethical intentions to fire an employee for blogging, while individual perceptions of ethical values were negatively associated with unethical intentions. Finally, subjects perceived that terminating an employee for innocuous blogging that did not target an employer was more ethically intense than was firing an employee for work‐related blogging. The implications of the findings for human resource professionals are discussed, as are the study's limitations and suggestions for future research. © 2010 Wiley Periodicals, Inc.     

Second in command: the misunderstood role of the chief operating officer

Asking the question,"What makes a great COO?" is akin to asking "What makes a great candidate for U.S. vice president?" It all depends on the first name on the ticket--the CEO. New research sheds light on this most contingent, and most mysterious, of C-suite jobs. After in-depth conversations with dozens of executives who have held the position and with CEOs who have worked with COOs, the authors have concluded that different views of the COO role arise from the different motives behind creating the position in the first place. There are seven basic reasons why companies decide to hire a COO: to implement the CEO's strategy; to lead a particular initiative, such as a turnaround; to mentor a young, inexperienced CEO; to complement the strengths or make up for the weaknesses of the CEO; to provide a partner to the CEO; to test out a possible successor; or to stave off the defection of a highly valuable executive, particularly to a rival. This tremendous variation implies that there is no standard set of great COO attributes, which makes finding suitable candidates difficult for companies and recruiters alike. Still, certain common success factors came up consistently in the interviews, the most important being building a high level of trust between CEO and COO. Trust comes from meeting obligations on both sides: The COO must truly support the CEO's vision; keep ego in check; and exhibit strong execution, coaching, and coordination skills. The CEO must communicate faithfully, grant real authority and decision rights, and not stymie the COO's career. It's surprising that COOs are not more common. They would be, the authors contend, if there were less confusion surrounding the role. As we continue to demystify that role, more companies will benefit from more effective leadership.     

Incremental State Higher Education Expenditures

Panel regressions are used to analyze various measures of state higher education expenditures for 45 states over a time period from 1986 through 2005. Results of panel stationarity tests indicate that each expenditures series contains a unit root. This finding is consistent with the incremental theory of public expenditures and implies that time series of these variables should be differenced if used as dependent variables in regression models. Regression results indicate that changes in state higher education expenditures are significantly procyclical. State higher education spending appears to fully adjust to population growth and over-adjust to CPI inflation. Larger state governments are associated with significantly larger annual adjustments to per capita real state higher education expenditures. No significant evidence is found that state Medicaid or elementary education expenditures crowd out higher education spending.

Securitized banking and the run on repo

The panic of 2007–2008 was a run on the sale and repurchase market (the repo market), which is a very large, short-term market that provides financing for a wide range of securitization activities and financial institutions. Repo transactions are collateralized, frequently with securitized bonds. We refer to the combination of securitization plus repo finance as “securitized banking” and argue that these activities were at the nexus of the crisis. We use a novel data set that includes credit spreads for hundreds of securitized bonds to trace the path of the crisis from subprime-housing related assets into markets that had no connection to housing. We find that changes in the LIB-OIS spread, a proxy for counterparty risk, were strongly correlated with changes in credit spreads and repo rates for securitized bonds. These changes implied higher uncertainty about bank solvency and lower values for repo collateral. Concerns about the liquidity of markets for the bonds used as collateral led to increases in repo haircuts, that is the amount of collateral required for any given transaction. With declining asset values and increasing haircuts, the US banking system was effectively insolvent for the first time since the Great Depression.     

New Product Development Speed: Too Much of a Good Thing?

New product development (NPD) speed has become increasingly important for managing innovation in fast‐changing business environments due to continuous reduction in the product life cycle time and increase in competition from technological advancements and globalization. While the existing literature has not produced consistent results regarding the relationship between speed and success for NPD projects, many scholars and practitioners assert that increasing NPD speed is virtually always important to NPD success. The purpose of this paper is to examine the implicit assumption that faster is better as it relates to new product success (NPS). From the perspectives of time‐compression diseconomies and absorptive capacity, the authors question the assumption that speed has a linear relationship with success. The authors further argue that time‐compression diseconomies depend on levels of uncertainty involved in NPD projects. Using survey data of 471 NPD projects, the hypotheses were tested by hierarchical regression analysis and subgroup polynomial regression. The results of this study indicate that NPD speed has a curvilinear relationship with NPS, and the nature of the speed–success relationship varies, depending on type and level of uncertainty. When turbulence or technological newness is high, the relationship is curvilinear, but when uncertainties are low, the relationship is linear. In contrast, the results of this study suggest a curvilinear relationship under conditions of low market newness but not when market newness is high. The present paper asserts that time‐compression diseconomies and absorptive capacity are important theoretical constructs in understanding speed in NPD. The different impact of market newness and market turbulence on NPD speed supports the distinction of newness and turbulence as two different sources of uncertainty. Discussion focuses on the implications of NPD speed under the different conditions of uncertainty. NPD teams need to pursue NPD speed as a critical strategy, but it is necessary to analyze the source and degree of uncertainty about projects before a time‐based strategy is selected. In order to address the challenges of high uncertainty, a firm needs to probe, learn, and iterate fast. In particular, NPD teams need to distinguish between the different requirements for new products in emerging and new markets, and those in fast‐changing markets. Moreover, NPD teams need to balance how fast they need to go with how fast they can go by considering team absorptive capacity and customer absorptive capacity.     

Housing tenure transitions of older households: Life cycle, demographic, and familial factors

Understanding the housing choices of the older households will grow in importance as the baby boom generation starts to retire. This analysis utilizes a rich longitudinal data set (PSID) to provide insight into the reasons why older households make housing transitions. Because of the richness of the data, this analysis is able to control for life transitions, a household's income and wealth, and connection to one's children in predicting when a homeowner makes a housing transition. The results demonstrate that age is not related directly to housing tenure choice for older households. Instead, having lower health status and being a single head of household is the important predictor of housing tenure transitions. At the same time, very few life changing events immediately lead a homeowner to become a renter, although they do influence the decision to downsize or consumer home equity. Finally, living next to one's children lowers the probability of becoming a renter or downsizing, and having richer children increases the probability of downsizing and thereby consuming one's housing wealth.     

Second‐gift behaviour of first‐time donors to charity: an empirical study

• This study examined the second‐time charity giving behaviour of a sample of 551 young people during a 2‐year period following the occurrence of their first ever significant donation. It explored the factors that encouraged an individual to make a second gift, the probabilities that a donation would be made within certain time intervals after the initial gift (3 months, 6 months, a year, etc.) and the variables that influenced whether the second donation would go to the charity receiving the person's first gift or to a different charity. Relevant issues were investigated via a Cox proportional hazards regression analysis and through a binary logistic regression. Covariates employed in the course of the study included the degree of emotional uplift a person experienced and the level of mind‐set change that took place consequent to a first donation, donor confusion with the range and variety of charities available and the reputation and image congruity of the second charity to which the participant had contributed. The roles of personal inertia and social pressure when making donation decisions were also examined.

Experimental methods: Between-subject and within-subject design

In this article we explore the issues that surround within-subject and between-subject designs. We describe experiments in economics and in psychology that make comparisons using either of these designs (or both) that sometimes yield the same results and sometimes do not. The overall goal is to establish a framework for understanding which critical questions need to be asked about such experimental studies, what authors of such studies can do to ameliorate fears of confoundedness, and which scenarios are particularly susceptible to divergent results from the two approaches. Overall, we find that both designs have their merits, and the choice of designs should be carefully considered in the context of the question being studied and in terms of the practical implementation of the research study.     

Response Strategies and Learning in Discrete Choice Experiments

This study explores ordering effects and response strategies in repeated binary discrete choice experiments. Mechanism design theory and empirical evidence suggest that repeated choice tasks per respondent induce strategic behaviour. We find evidence that strategic opportunities provided by the order in which choice sets are presented to respondents affect choice decisions (strategic response). The results suggest, however, that respondents may solely respond to high cost rather than low cost inconsistencies. That is, respondents are more cost sensitive, and thus have a lower willingness to pay (WTP), if the same or a similar level of provision was offered in a previous choice set at a lower cost than if it was not. Yet, the cost sensitivity, and thus WTP, remains unaffected if the same or a similar level of provision was offered in a previous choice set at a higher cost. Our findings further indicate that cost sensitivity increases (and thus WTP decreases), when respondents progress through the choice task, with this increase (decrease) lessening as more choice questions are answered. Possible explanations are value learning and strategic learning.
