Prices and Information Under Imperfect Competition

Imperfectly competitive product markets cannot be informationally efficient as private information has strategic implications interfering with price adjustment. This is illustrated in a duopoly model with sequential price setting where private information either leads to prices not being adjusted to all available information or to adjusted but biased prices.     

On myopia as rationale for social security

It has been argued that “paternalistically motivated forced savings constitutes an important, and to some the most important, rationale for social security retirement systems.” This paper revisits the role played by myopia in generating a theoretical rationale for pay-as-you-go (PAYG) social security in dynamically efficient economies. If the competing asset is linear storage and myopic agents are allowed to borrow against future pension benefits, there is no welfare-rationale for PAYG pensions. Sufficiently strong myopia may justify such pensions only if agents cannot borrow against their future pension, but then they are at a zero-saving corner. With enough myopia, co-existence of positive optimal pensions and positive private saving is possible if the return to saving declines with saving, as in a model with a neoclassical technology.     

Realized volatility forecasting and market microstructure noise

We extend the analytical results for reduced form realized volatility based forecasting in ABM (2004) to allow for market microstructure frictions in the observed high-frequency returns. Our results build on the eigenfunction representation of the general stochastic volatility class of models developed byMeddahi (2001). In addition to traditional realized volatility measures and the role of the underlying sampling frequencies, we also explore the forecasting performance of several alternative volatility measures designed to mitigate the impact of the microstructure noise. Our analysis is facilitated by a simple unified quadratic form representation for all these estimators. Our results suggest that the detrimental impact of the noise on forecast accuracy can be substantial. Moreover, the linear forecasts based on a simple-to-implement ‘average’ (or ‘subsampled’) estimator obtained by averaging standard sparsely sampled realized volatility measures generally perform on par with the best alternative robust measures.     

Analytical methods for planning educational facilities in an era of declining enrollments

With declining enrollments, metropolitan school districts are faced with problems of property disposition. A school facilities planning and management model utilizing a linear programming approach enables assessment of alternative uses for school facilities. The objective in this study is to minimize expenditures subject to constraints which include a limit to distance traveled, racial ethnic quotas, and overhead costs, such as transportation, maintenance and energy. An economic post-optimal cost sensitivity analysis of the proposed options is presented and also a comparison of this approach to school management with others found in the literature.     

Industrial ecology and some implications for rural SMEs

In a project at Western Norway Research Institute, the concept of industrial ecology (IE) is used as a framework for environmental performance of small- and medium sized enterprises (SMEs) in Norway. The main goal of the project ‘Green SMEs’ is to identify existing and future environmental challenges for rural SMEs. The focus is on external demands coming from the surroundings of the individual businesses. Examples of issues being dealt with are industrial wastes becoming sources of raw materials for other industries, design and material choice for disassembly and reuse, development of industrial ecosystems, and industrial metabolism. This paper presents actual examples of industrial ecosystems and also some cases illustrating the problems small remotely located firms meet when the principles of IE are to be applied. These problems include the inability to participate in efficient industrial ecosystems (webs) with exchange of wastes to raw materials. Larger companies, often being more centrally located, have greater chances at identifying and attracting other businesses which they can co‒operate with in finding usage for their wastes. The ‘cluster’‒properties of efficient industrial ecosystems can therefore be a limiting factor in the development of such systems in rural areas. Small companies also have less opportunities to be proactive in establishing industrial ecosystems also merely due to the smaller scale of their operations. © 1997 John Wiley & Sons, Ltd. and ERP Environment.     

Diverging expectations in buyer-seller relationships: Institutional contexts and relationship norms

Many firms assume that outsourcing partnerships may allow them to strengthen their overall competitiveness. Lured by its intuitive appeal, several enter into such partnerships, only to realize that they represent a marginal rather than a magical solution to their quest for increasing market performance. An important reason for this is the diverging beliefs and expectations held by both parties in the buyer-seller dyad. The purpose of this contribution is to develop a framework for understanding the divergences in expectations and relationship norms in cross-cultural business relationships among SMEs. We discuss four relational expectations derived from the B2B literature on relational norms for addressing these divergences: Quality, frequency and scope of communication, role specifications and coordination of work nature of planning horizons, and trustworthiness and link these to relationship performance. We explore the proposed impact of diverging relationship norms on relationship expectations using data from an ongoing field study of Danish buyers and Chinese suppliers. We link these diverging expectations to the business practices of Danish buyers and Chinese and their institutional contexts. In the concluding part of the paper, we discuss our findings and outline implications for management and academia.     

Governance mode for port congestion mitigation: A transaction cost perspective

Transaction cost analysis (TCA) has been applied in a wide range of academic disciplines, including economics, marketing, sociology, organization theory, and business strategy. Literature in maritime transport has had limited exposure to this versatile theoretical framework. This paper aims at developing a conceptual model that describes governance strategies that various players within the maritime sector can adopt to mitigate congestion at ports. A TCA is used to examine port congestion mitigation from a governance perspective. A theoretical analysis conducted for this paper reveals that the three characteristics of TCA – asset specificity, frequency, and uncertainty – prevail in the maritime sector, too. The first two factors, frequency, and uncertainty, contribute to port congestion, while the third factor, asset specificity, exists because to release port congestion, some players ought to make a specific investment. We use TCA to discuss the circumstances under which governance modes such as bilateral governance and vertical integration should be used to avoid congestion and other kinds of transaction costs associated with these three attributes in the maritime sector. In this study, we suggested several testable propositions to identify the mode of governance that should be selected by stakeholders to mitigate port congestion and to protect specific investments made to release congestion at ports. This line of analysis will certainly provide all the stakeholders engaged (particularly, a public policymaker) useful insight into understanding congestion from a governance perspective.     

The Role of Human Resource Management in Strategy Making

Among the strategy scholars, there is general consensus that responsive‐integrative strategy making is essential for ensuring a competitive advantage in contemporary dynamic environments. What is the role of HR in this process, and how can HR support responsive‐integrative strategy making? To answer these questions, we use illustrative experiences from Chr. Hansen, a global supplier of bioscience‐based ingredients to the food, health, and animal feed industries. We argue that HR's strategic role lies in providing support for both centralized and decentralized strategy making by offering aspirations for strategic decisions and by gathering various sources of inspiration for strategy discussions. © 2013 Wiley Periodicals, Inc.     

A Review on Possible Approaches for Detecting Early Warning Signs in Projects

In this paper, we attempt to provide an overview of the full extent of early warning detection approaches, which are directly or indirectly addressed in the literature. These approaches can aid project managers in taking corrective actions timely enough for preventing failures. The study is based on a review of the current literature within the field of early warning in project management and our own experiences gained from practice. An analysis of the strengths and weaknesses of each approach and their applications in different contexts are also performed. We conclude that the choice of the most effective approach is arguably dependent on the type of project, organizational culture, and the project environment.
