Time-consistency in managing a commodity portfolio: A dynamic risk measure approach

We address the problem of managing a storable commodity portfolio, that includes physical assets and positions in spot and forward markets. The vast amount of capital involved in the acquisition of a power plant or storage facility implies that the financing period stretches over a period of several quarters or years. Hence, an intertemporally consistent way of optimizing the portfolio over the planning horizon is required. We demonstrate the temporal inconsistency of static risk objectives based on final wealth and advocate the validity in our setting of a new class of recursive risk measures introduced by Epstein and Zin [Epstein, G., Zin, S., 1989. Substitution, risk aversion, and the temporal behavior of consumption and asset returns: A theoretical framework. Econometrica, 57 (4) 937–969] and Wang [Wang, T., 2000. A class of dynamic risk measures University of British Columbia]. These risk measures provide important insights on the trade-offs between date-specific risks (i.e., losses occurring at a point in time) and time-duration risks represented by the pair (return, risk) over a planning horizon; in a number of situations, they dramatically improve the efficiency of static risk objectives, as exhibited in numerical examples.     

Trading House Price Risk with Existing Futures Contracts

This paper examines the use of futures contracts to hedge residential real estate price risk. We examine whether existing futures contacts can effectively be used to offset volatility in national house prices. Little evidence of any simple systematic relation between national prices and futures prices is found. Since house prices are not easily replicated with a portfolio of existing futures contracts, a further implication is that the Chicago Mercantile’s introduction of a financial asset whose value reflects house prices will help complete the market. Nevertheless, the success of the CME’s new derivative contracts may be limited in light of state and regional house price correlations.

Can corporate governance save distressed firms from bankruptcy? An empirical analysis

We examine financially distressed firms and document how governance characteristics affect (1) a firm’s ability to avoid bankruptcy and (2) the power of financial/accounting information to predict bankruptcy. Overall, our findings indicate that a distressed firm’s governance characteristics significantly affect its probability of bankruptcy. We find that smaller and more independent boards with a higher ratio of non-inside directors and with larger ownership stakes of inside directors are more effective at avoiding bankruptcy once distress is indicated. These results are consistent with the belief that these types of governance structures induce more effective monitoring. The results are also consistent with the view that the inclusion of governance characteristics enhances the power of financial accounting models in predicting bankruptcy.

Real Options, International Entry Mode Choice and Performance

abstract    Recent scholarship suggests that combining insights from real option theory with transaction cost economics may improve decision-making models. In response to this suggestion we develop and test a model of international entry mode choice that draws from both perspectives. Examining samples of Dutch and Greek firms entering Central and Eastern European markets, we found that adding real option variables to a transaction cost model significantly improved its explanatory power. Additionally, firms that used the combined real option/transaction cost predicted choices had significantly higher levels of subsidiary performance satisfaction than firms that did not. Our results suggest that effective managerial decision-making may involve more than mere transaction cost minimization considerations; real option value creation insights also appear to influence the success of decision outcomes.     

Conversations during purchase consideration: sales assistants and customers

Conversations among and between our fellow customers and sales personnel provide social and informational exchange to support material exchange in retail settings. A 2 x 2 factorial field experiment (in a ladies' clothing retailing context) was undertaken to compare perceptions of the effects of oral contributions made by sales assistants, and by fellow customers, on levels of satisfaction, purchase intentions and credibility during the service experience. Conversations with other customers are shown to lead to greater perceived satisfaction in the consideration phase than those with sales assistants. Sales assistants are confirmed as less credible, and the notion that spoken interactions with assistants may lead to increased purchase intention is rejected.     

Beyond Seniority-Based Systems: A Paradigm Shift in Korean HRM?

This study compares work organization and labour relations at three assembly plants: the Ford Escort plant in Wayne, Michigan; the Ford Escort-Tracer plant in Hermosillo, Mexico; and the Mazda-Ford joint venture in Flat rock, Michigan. All three plants are commonly understood to be ‘team concept’ work environments; all three also exhibit a common technical organization derived from the same Mazda-Ford engineering set-up. However, the social organizatin of each plant's work teams is substantially different. The single most important variable in shaping these contrasting outcomes was the role of the union: aggressively involved in the earliest planning for team production at Wayne, while arriving late at Flat Rock and adopting a passive role. When the UAW local at Flat Rock elected more militant leaders, this evolving dynamic pushed in the direction of worker-centred teams; conversely, when the union in the Ford Hermosillo plant was weakened by company reprisals following a bitter strike, management was free to push in the direction of supervisor-centred teams.     

Remuneration practices in the UK hospitality industry in the age of the national minimum wage

This article examines why the introduction of the National Minimum Wage has been less disruptive in hospitality than had been anticipated. It shows that in hospitality establishments pay rates are not the outcome of managerial decision making alone, but are influenced by broader economic and social processes. Furthermore, key aspects of the ‘total reward system’ held to exist in hospitality, the provision of live-in accommodation for workers and the practice of tipping, on which there are specific National Minimum Wage regulations, are generally not treated as remuneration. This highlights the need for a reconsideration of how remuneration practices in hospitality operate.     

Trusting and Monitoring Business Partners throughout the Relationship Life Cycle

Purpose: The goal of this research is to understand the theoretical and empirical confluence of multi-dimensional trust with the role of monitoring as business partnerships unfold and evolve dynamically throughout the course of the relationship life cycle.

Methodology: A pilot study is run in which in-depth interviews are conducted with managers to glean their insights regarding the theoretical questions and to verify terminology for survey items. A large-scale survey study is then conducted to test hypotheses about the relationships among the focal constructs. The participants in both studies are real procurement professionals reporting on their primary supplier relationships. The qualitative study and the samples of real world managers enhance the external validity of this research.

Findings: In early stages of business relationships, monitoring and benevolence trust interact to positively impact business performance. Continued monitoring in later stages interact with benevolence trust to performance detriment. Conversely, monitoring and competence aspects of trust hurt business performance in earlier life stages.

Research Implications: Theoretical frameworks that include the constructs of multidimensional trust, monitoring, and relationship life cycle stages can build on the nuanced 3-dimensional contingencies established in this research. In particular, this research furthers the concepts of monitoring and the relationship life cycle.

Practical Implications: There is a time and a place to trust one's business partners, and a time and a place to verify their trustworthiness. As business partnerships are forged, monitoring and benevolence trust can be particularly fruitful.

Contribution: In this research, the authors build on the business marketing literature that has begun to delineate the benevolence and competence dimensions of trust in business relationships; they demonstrate the role that partner monitoring has in maintaining business commitments; and establish how these effects are modified over the stages of the relationship life cycle; i.e., from exploration, to build-up, maturity, and decline.     

PRICE-LEVEL TARGETING AND STABILISATION POLICY: A SURVEY

Abstract.  This paper surveys recent articles on the costs and benefits of price-level targeting, focusing its use as a tool for stabilisation policy. It discusses how price-level targeting can affect the short-run trade-off between output and inflation variability by influencing inflation expectations. It reviews how assigning an explicit price-level target to a central bank that is unable to commit to its future policies can improve economic performance. It surveys other potential benefits and costs. Among the costs, it underlines the importance of perfectly rational expectations for the optimality of price-level targeting, and an exacerbation of the time inconsistency problem.
