The correlation coefficient and problems of inference in recreation research

Correlation analysis frequently has been used for the investigation of leisure research questions. This paper illustrates the problem of “unequal weighting of cases” which is present in the use of correlation analysis. It further illustrates how this problem can mislead researchers when they make substantive inferences about leisure.     

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.     

Long memory in stock market volatility and the volatility-in-mean effect: The FIEGARCH-M Model

We extend the fractionally integrated exponential GARCH (FIEGARCH) model for daily stock return data with long memory in return volatility of Bollerslev and Mikkelsen (1996) by introducing a possible volatility-in-mean effect. To avoid that the long memory property of volatility carries over to returns, we consider a filtered FIEGARCH-in-mean (FIEGARCH-M) effect in the return equation. The filtering of the volatility-in-mean component thus allows the co-existence of long memory in volatility and short memory in returns. We present an application to the daily CRSP value-weighted cum-dividend stock index return series from 1926 through 2006 which documents the empirical relevance of our model. The volatility-in-mean effect is significant, and the FIEGARCH-M model outperforms the original FIEGARCH model and alternative GARCH-type specifications according to standard criteria.     

An environmental performance index for products reflecting damage costs

Several studies have demonstrated how to use DEA (Data Envelopment Analysis) based techniques to estimate environmental performance indices. None of these studies, however, are taking information on the environmental damage costs of the pressure types considered into account. This study is bridging a gap between environmental indices founded in physical pressures and damage costs founded in welfare economics. The aim of the paper is twofold: first, to demonstrate how to implement the information on environmental damage costs within a DEA based environmental performance index, and second, to estimate these indices at product level by using Danish input-output data and environmental data from 1997.     

The Stewardship Role of Analyst Forecasts,and Discretionary Versus Non-discretionary Accruals

We examine the interaction between discretionary and non-discretionary accruals in a stewardship setting. Contracting includes multiple rounds of renegotiation based on contractible accounting information and non-contractible but more timely non-accounting information. We show that accounting regulation aimed at increasing earnings quality from a valuation perspective (earnings persistence) may have a significant impact on how firms rationally respond in terms of allowing accrual discretion in order to alleviate the impact on the stewardship role of earnings. Increasing the precision of more timely non-accounting information (analyst earnings forecasts) increases the ex ante value of the firm and reduces costly earnings management. There is an optimal level of reversible non-discretionary accrual noise introduced through revenue recognition policies. Tight rules-based accounting regulation, as opposed to leaving firms more choice over non-discretionary accrual policies, may lead firms to rationally respond by inducing costly earnings management. More generally, regulating both earnings persistence and the tightness of admissible auditing policies may not result in less equilibrium earnings management.     

Environmental Innovations in Small and Medium Sized Enterprises

Supporting and accelerating the adoption and diffusion of environmental innovations amongst small and medium sized enterprises (SMEs) is a major challenge to environmental policy makers. Research suggests that whilst SMEs possess high flexibility, their innovative capacity may be limited to incremental changes within their existing technology system and network. Twenty case studies examining the innovation adoption process in SMEs in four sectors and in five countries within the ENVIS project (commissioned by the EU) revealed great variety in factors driving this process. Findings indicate that this variation can be attributed to the character of the environmental innovation, the specific business opportunity, the regulatory setting and pressure experienced by the sector. Based on these findings an analytical framework is suggested, whereby the environmental innovative capability of SMEs is conceived as the result of an interplay between the competencies, the network relations and the strategic orientation of the company (the 'dynamic triangle'). This indicates that policy to support SME's adoption of environmental innovations has to take an integrated form, i.e. addressing and developing competence, networks and strategic orientation of SMEs simultaneously whilst remaining systemic and context sensitive.     

A Tutorial on Palm Distributions for Spatial Point Processes

This tutorial provides an introduction to Palm distributions for spatial point processes. Initially, in the context of finite point processes, we give an explicit definition of Palm distributions in terms of their density functions. Then we review Palm distributions in the general case. Finally, we discuss some examples of Palm distributions for specific models and some applications.     

Innovative Assets And Inter-Asset Linkages—A Resource-Based Approach To Innovation

The paper proposes a framework for analyzing assets and inter-asset linkages associated with technological innovation. The framework is consistent with a Penrosian view of the firm and draws on recent contributions from both the more general resource-based perspective and the innovation and technology perspective of the firm.

Three broad categories of firm assets are distinguished: tradeable resources, technical/functional capabilities and managerial competences. Assets for technological innovation are defined as resources, technical capabilities and managerial competences for developing new products and processes. A taxonomy of generic innovative assets is proposed that distinguishes four generic categories of innovative assets: Scientific research assets, process innovative assets, product innovative application assets and aesthetic design assets. Critical inter-asset linkages are analyzed in terms of inter-asset specificity. It is argued that high degrees of inter-asset specificity provide greater scope for innovation and make higher demands on the innovative assets and their coordination than low degrees of inter-asset specificity. It is moreover suggested that complementary assets not only play the role of assuring proper commercialization of given innovations; they may also play a critical role as a ‘focusing device’ for directing the innovative process.

Finally, some implications for strategy in innovative firms are indicated. Thus, the proposed inter-asset framework may help to specify the notion of core competences and provide a more differentiated perspective on innovation strategy and first-mover advantages.     

Shooting fish in the barrel? Examining the standard test of the Lucas variability hypothesis

The LVH (Lucas variability hypothesis) says that the reaction of real output to changes in nominal demand depends negatively upon the variability of the rate of change of nominal demand. The LVH was first proposed as a testable prediction from R. E. Lucas' 1973 model of the business cycle – known as the misperceptions model. The LVH has frequently been successfully tested on cross-country data sets. We first replicate the standard test result. We then proceed to show that the test suffers from the problem that the same LVH-test result appears – qualitatively and quantitatively – even in models having the reverse causal structure, from the one assumed by Lucas. We have consequently shown that the LVH-test is developed within a framework where it is hard to miss -hence the title.
