Managers as informal third parties: The impact of supervisor-subordinate relationships on interventions

This research focuses on the distinctions between formal and informal third parties articulated by Kolb and Sheppard (1985), the most important of which is the relationship that exists between the third party and the disputants. Several hypotheses are advanced regarding the consequences of a sudden change in the relationship on the process and outcomes of the intervention. An experimental simulation of a supervisor-subordinate discussion (about a dispute among subordinates) is conducted with 62 undergraduate volunteers as participants. The supervisors in the experimental group receive negative affective information about the subordinate prior to the meeting, which is expected to influence the relationship and hence the intervention. Results indicate that in the experimental condition performance evaluations were lower, ratings of trust were lower, and the atmosphere in the discussion was rated as less friendly. Interestingly, in dyads where the negative information was discussed openly each of the ratings was higher than when the negative information was not discussed, as was the satisfaction reported by each of the participants. The implications of these findings for future research are discussed.     

Procurement mechanisms and the emergence of new governance structures in the CEECs: evidence from the Bulgarian wine industry

During transition, Bulgaria witnessed the dismantling of communist agri-food supply channels and a weakening of contract enforcement mechanisms. Wineries have had to establish grape procurement and purchasing relationships with a more diverse set of growers and intermediaries. In an attempt to overcome the weaknesses of procurement via spot markets, they have sought more interdependent contractual forms that secure greater control over the quality of inputs and minimise the possibility of opportunistic behaviour. The desired option by wineries is complete backward integration but attempts to achieve this have been limited by fragmented land ownership, credit constraints and incomplete property rights.     

Throwing good money after bad

An “investment bubble” is a period of “excessive, and predictably unprofitable, investment” (DeMarzo et al. in J Financ Econ 85:737–754, 2007). Such bubbles most often accompany the arrival of some new technology, such as the tech stock boom and bust of the late 1990s and early 2000s. We provide a rational explanation for investment bubbles based on the dynamics of learning in highly uncertain environments. Objective information about the earnings potential of a new technology gives rise to a set of priors or a belief function. A generalised form of Bayes’ rule is used to update this set of priors using earnings data from the new economy. In each period, agents—who are heterogeneous in their tolerance for ambiguity—make optimal occupational choices, with wages in the new economy set to clear the labour market. A preponderance of bad news about the new technology may nevertheless give rise to increasing firm formation around this technology, at least initially. To a frequentist outside observer, the pattern of adoption appears as an investment bubble.     

Short-run efficiency in the labor-managed firm

This paper examines the short-run comparative statics of resource allocation in a labor-managed firm when workers are free to adjust work hours but not membership in a competitive market environment. It is found that the workers might encounter difficulties in attaining their utility-maximizing choices of work hours, but with the acceptance of a simple collective-choice decision rule, each worker's optimum becomes the Pareto-optimum.     

Second order multiscale stochastic volatility asymptotics: stochastic terminal layer analysis and calibration

Multiscale stochastic volatility models have been developed as an efficient way to capture the principal effects on derivative pricing and portfolio optimization of randomly varying volatility. The recent book by Fouque et al. (Multiscale Stochastic Volatility for Equity, Interest-Rate and Credit Derivatives, 2011) analyzes models in which the volatility of the underlying is driven by two diffusions – one fast mean-reverting and one slowly varying – and provides a first order approximation for European option prices and for the implied volatility surface, which is calibrated to market data. Here, we present the full second order asymptotics, which are considerably more complicated due to a terminal layer near the option expiration time. We find that to second order, the implied volatility approximation depends quadratically on log-moneyness, capturing the convexity of the implied volatility curve seen in data. We introduce a new probabilistic approach to the terminal layer analysis needed for the derivation of the second order singular perturbation term, and calibrate to S&P 500 options data.     

Crafting Compromises in a Strategising Process: A Case Study of an International Development Organisation

This paper focuses on how organisational members in non‐governmental organisations (NGO) can develop credible and legitimate strategic plans and positions out of diverse and conflicting perspectives. Using empirical data drawn from a strategic planning episode in an international development NGO, the study examines the process of ‘crafting compromises’ whereby organisational members make mutual adjustments and concessions to reach consensus on new strategic plans and positions. The analysis shows that two processes facilitate crafting compromises in strategising; being adaptive and responsive to critique as strategic positions are developed, and an ability to forge relevant connections between new strategic proposals and past strategic positions.     

The Dodd‐Frank Wall Street Reform and Consumer Protection Act: Accomplishments and Limitations*

The Dodd‐Frank Wall Street Reform and Consumer Protection Act of 2010 is widely described as the most ambitious and far‐reaching overhaul of financial regulation in the United States since the 1930s. Together with other regulatory reforms introduced by regulatory agencies globally, the Act aims to put an end to the too‐big‐to‐fail problem and is expected to alter the structure of financial markets in profound ways. This article provides an overall assessment of the Act in three different ways: first, in light of first economic principles, or how theory suggests we should regulate the financial sector, given the systemic risk externality each financial firm imposes on other firms and the rest of the economy; second, from a comparative perspective that views the proposed reforms in relation to those undertaken in the 1930s following the Great Depression; and, finally, in the form of an assessment of how the proposed reforms would have fared in preventing and dealing with the crisis of 2007–2009 had they been in place at the time. The article also highlights key areas that are left wholly or partly unaddressed by the Dodd‐Frank Act—notably, the pricing of explicit and implicit government guarantees; dealing with inevitable opportunities for the financial sector to engage in regulatory arbitrage; and containing the systemic risk arising from collections of small institutions and markets such as money market funds and repo contracts.     

Using ‘Electronic Portfolios’ to Challenge Current Orthodoxies in the Presentation of an Initial Teacher Training Design and Technology Activity

The paper examines the extent to which a University undergraduate curriculum initiative provided initial teacher trainees with opportunities to challenge orthodox design methodologies through the production of an electronic portfolio within and extended design and technology activity. It was found that the ‘electronic portfolio’ served primarily as a developmental tool for promoting creative continuity and sound, reflective, design practice within a structured educational design challenge. The portfolio also provided a focus for the development of ‘e’ learning skills as it facilitated the use of new technologies in the compilation of the portfolio. Additionally, the portfolio provided trainees with a means by which they were able to demonstrate their capability to prospective employers. The use of the ‘electronic portfolio’ challenges current orthodoxy and methods routinely employed to present and assess trainees’ creative work, which have been shown to constrain innovative practice. The paper concludes that the use of the ‘electronic’ portfolio was successful in facilitating trainees’ engagement with a creative Design and Technology process.     

External COO/presidents as expert directors: A new look at the service role of boards

Much of the scholarship on boards of directors has examined either the control (i.e., monitoring) role or the resource dependence role that boards fill. Relatively little has examined the service role, wherein directors provide advice and guidance to management. This study builds on recent work exploring director expertise by asking how operational expertise on boards impacts firm performance. We find that having external COO/presidents on a board of directors positively impacts firm performance when the firm's operational efficiency is declining, but negatively impacts performance when the firm's operational efficiency is improving. We also find that other types of external executives serving as directors exhibit the opposite relationship, suggesting that the value of director expertise is context‐dependent. We discuss the implications of these findings for director selection. Copyright © 2013 John Wiley & Sons, Ltd.
