Testing the null hypothesis of no regime switching with an application to GDP growth rates

This paper presents tests for the null hypothesis of no regime switching in Hamilton’s (Econometrica 57:357–384, 1989) regime switching model. The test procedures exploit similarities between regime switching models, autoregressions with measurement errors, and finite mixture models. The proposed tests are computationally simple and, contrary to likelihood based tests, have a standard distribution under the null. When the methodology is applied to US GDP growth rates, no strong evidence of regime switching is found.

The Economic Value of Water Quality

Stated preference values for water quality ratings based on the US Environmental Protection Agency National Water Quality Inventory ratings provide an operational basis for benefit assessment. Iterative choice survey results for a very large, nationally representative, Web-based panel imply an average valuation of $32 for each percent increase in lakes and rivers in the region for which water quality is rated “Good.” Valuations are skewed, with the mean value more than double the median. Sources of heterogeneity in benefit values include differences in responses to average water quality information and the base level of water quality. Conjoint estimates are somewhat lower than the iterative choice values. The annual economic value of the decline in inland US water quality from 1994 to 2000 is over $20 billion.      

Testing time-homogeneity of rating transitions after origination of debt

When modelling rating transitions as continuous-time Markov processes, in practice, time-homogeneity is a common assumption, yet restrictive, in order to reduce the complexity of the model. This paper investigates whether rating transition probabilities change after the origination of debt. Accordingly, we develop a likelihood-ratio test for the hypothesis of time-homogeneity. The alternative is a step function of transition intensities. The test rejects time-homogeneity for rating transitions observed over 7 years in a real corporate portfolio. Especially 1-year transition probabilities increase over the first year after origination. This time effect suggests that banks should manage their credit portfolios with respect to the age of debt.      

Corporate social responsibility: attributions,loyalty, and the mediating role of trust

This study investigates whether consumers’ perceptions of motives influence their evaluation of corporate social responsibility (CSR) efforts. The study reveals the mediating role of consumer trust in CSR evaluation frameworks; managers should monitor consumer trust, which seems to be an important subprocess regulating the effect of consumer attributions on patronage and recommendation intentions. Further, managers may allay the negative effects of profit-motivated giving by doing well on service quality perceptions. On the other hand, appropriately motivated giving continues to positively affect trust regardless of the performance of the firm on service quality provision.     

On the importance of matching strategic behavior and target market selection to business strategy in high-tech markets

Business strategy is fundamentally concerned with the actions required to create superior customer value in the firm’s target markets with the ultimate goal of achieving superior performance. Marketing theory suggests that two critical marketing activities required to achieve this end are: (1) the adoption of appropriate strategic behaviors (i.e., customer-oriented, competitor-oriented, technology-oriented) and (2) targeting of the appropriate market segments (i.e., innovators, early adopters, early majority, late majority, laggards). This study builds on prior research which demonstrates that the strategic behavior—firm performance relationship is contingent on the firm’s strategy by examining this relationship in high tech markets and by considering the incremental contribution of appropriate target market selection. Responses from 160 senior marketing managers in high-tech firms reveal strong support for our framework. Thus, this study provides useful guidance to executives and managers in high-tech firms regarding the steps that they should take to increase their probability of success.

Valuing animal genetic resources: a choice modeling application to indigenous cattle in Kenya

In an effort to improve productivity and profits, many farmers have replaced traditional livestock breeds with higher yielding alternatives. While such changes may bring about short‐term economic gains, the loss of traditional livestock breeds could result in the loss of an important genetic resource as a variety of important genetic traits adapted to local conditions gradually become less common in the population. This is a particular problem in Africa, where livestock make a substantial contribution to human livelihoods. Using the example of cattle in Kenya's pastoral livestock markets this study uses a choice experiment approach to investigate buyers' preferences for indigenous breeds such as the Maasai Zebu. The analysis employs a latent class approach to characterize heterogeneity in valuations both within and across respondents buying cattle for breeding, slaughter, or resale. The results show that there are at least three classes of buyers with distinct preferences for cattle traits and that most buyers favor exotic rather than indigenous breeds. Such preferences have implications for the conservation of indigenous cattle in Kenya and in other developing countries and suggest that some form of intervention may be required to ensure the preservation of this important animal genetic resource.     

Schadenfreude: The (not so) Secret Joy of Another’s Misfortune

Despite growing interest in emotions, organizational scholars have largely ignored the moral emotion of schadenfreude, which refers to pleasure felt in response to another’s misfortune. As a socially undesirable emotion, it might be assumed that individuals would be hesitant to share their schadenfreude. In two experimental studies involving emotional responses to unethical behaviors, we find evidence to the contrary. Study 1 revealed that subjects experiencing schadenfreude were willing to share their feelings, especially if the misfortune was perceived to be deserved (i.e., resulting from unethical behaviors). Study 2 extends this work by incorporating schadenfreude targets of different status (CEO versus employee). Consistent with the “tall poppy syndrome,” subjects were more willing to share schadenfreude concerning high status targets than low status targets when the perceived severity of the target’s misconduct was low. This status effect disappeared at higher levels of perceived deservingness, however. Reported willingness to share schadenfreude was strongest at these levels but did not differ significantly between high and low status targets. These findings build on the social functional account of emotions, suggesting that sharing schadenfreude may signal normative cues to others regarding workplace behaviors that are deemed to be unethical.     

Leadership: The Being Component. Can the Spiritual Exercises of Saint Ignatius Contribute to the Debate on Business Education?

In recent years, scholars have increasingly dedicated their attention to analyse and reflect on the topic of leadership. However, the debate has often focused on the figure of the leader, as if being a leader were a self-sufficient function in itself, understood without finalities or independent of them. I would argue that leadership is not a position that can be assumed, but, rather, a relationship that is constructed. Similarly, the question of leaders has often given rise to a deconstruction of its components, without any insight as to how the reality is put together. Leadership cannot be understood solely from a technical or instrumental perspective. It is not a mere relational skill that simply requires developing competencies. The exercise of leadership always includes—explicitly or implicitly—a connection with values. Therefore, developing leadership is impossible without a personal process that develops the person’s capacity for perception, learning, interiorisation, explicit sense-making and constructing meaning. These issues are truly important at a time in which the debate on business education and its contribution is completely open, targeting the very core of business education’s reason for being. Though open, the debate can only become a truly dynamic discussion if there is a real dialogue between the different positions and traditions. For this reason, this paper proposes an anthropological and non-denominational reading of some of the fundamental meditations found in the Spiritual Exercises of Saint Ignatius which could be used as a heuristic in the debate regarding what business schools propose. This paper represents an initial step in this direction, exploring some of the potentialities of the Spiritual Exercises for business schools that do not claim any religious tradition.
