Content validation of a measure of R&D effectiveness

The overall purpose of this paper is to analyse the content validity of a tool for measuring research and development (R&D) effectiveness in industry using an approach known as scale or construct validation.
Since a large number of indicators is needed in order to measure this concept, and it is often difficult to find qualitative measures that would provide more information than quantitative measures or purely numerical magnitudes, we have constructed a scale that enables us to create a multiindicator to measure R&D inputs, processes, outputs and results. This multiindicator also enables us to group together all the relevant data obtained from the R&D management literature, which we then validate by consulting the opinion of experts from two firms that are very active in R&D and we have consulted two more nationally recognized Spanish researchers on R&D.     

Die aktuelle Weltwirtschaftskrise und der ökologische Umbau der Wirtschaft

Die aktuelle Finanz- und Wirtschaftskrise und der Klimawandel haben gemeinsame Wurzeln, aber ganz unterschiedliche Wirkungen. Sie werden deshalb auch sehr verschieden wahrgenommen. Sie lassen sich nur bek?mpfen, wenn man klug aufeinander abgestimmte politische Ma?nahmen ergreift.     

Sectoral linkages of foreign direct investment firms to the Czech economy

Foreign direct investments (FDI) influence the industrial structure of the host economy through linkages to the domestic economy. Firms may use intermediate goods produced by either domestic or foreign firms, and sell their products to either domestic or foreign customers. The resulting change in the industrial structure of the indigenous economy is analysed in a panel regression for the case of the Czech Republic. The results show that linkages have a strong influence on the sectoral composition of the indigenous economy, supporting the development of indigenous manufacturing and labour-intensive industry.     

Customer desire expectations about service employees: An analysis of hierarchical relations

This article proposes a hierarchical model of customers' desire expectations about service employees, and of the motivations underlying the expectations. The model is based on recent developments in means–end chain theory. A paper-and-pencil laddering methodology is applied to collect data among 231 customers in Austria concerning their desire expectations about service employees of clothing stores. Additive tree and social network analyses reveal three orientations in customer desire expectations, covering the process, outcome, and relational aspects of service encounters. Meanings within orientations are mutually linked and hierarchically organized from desire expectations about specific service employees' behaviors, via customer goal attainments and feelings, to behavioral responses. Implications for service marketing theory and practice are offered. © 1998 John Wiley & Sons, Inc.     

Exit as governance: do blockholders affect corporate innovation in large US firms?

Using a sample of large US firms, this study shows that blockholders in combination with liquidity can contribute positively to innovation (R&D investments). We contribute to the literature on managerial myopia that has focused mainly on large owners and their type (short-term/long-term). Our results are in line with recent theoretical studies arguing that blockholders in combination with market liquidity can mitigate managerial myopia, as suggested by the exit model of governance. The results indicate that blockholders can be efficient in resolving agency problems and that they can enhance long-term prosperity, even when the individual blockholder investment horizon may not be long.     

Optimal portfolios when volatility can jump

We consider an asset allocation problem in a continuous-time model with stochastic volatility and jumps in both the asset price and its volatility. First, we derive the optimal portfolio for an investor with constant relative risk aversion. The demand for jump risk includes a hedging component, which is not present in models without volatility jumps. We further show that the introduction of derivative contracts can have substantial economic value. We also analyze the distribution of terminal wealth for an investor who uses the wrong model, either by ignoring volatility jumps or by falsely including such jumps, or who is subject to estimation risk. Whenever a model different from the true one is used, the terminal wealth distribution exhibits fatter tails and (in some cases) significant default risk.     

Ecotourism development in Ghana: A postcolonial analysis

Despite growing research on ecotourism in Ghana, it is unclear to what extent colonial approaches to forestry and wildlife conservation still influence ecotourism in the country. This paper examines ecotourism development in Ghana from a postcolonialist perspective. It is based on a thematic assessment of primary data from in-depth interviews with a range of ecotourism actors. The paper shows that ecotourism in Ghana, much like colonial forestry and wildlife conservation, faces challenges such as the marginalisation of the local community, the use of neo-crisis narratives, a dependence on international forces, and the marginalisation of local ecological knowledge. It argues for a holistic approach to the development of ecotourism as a win–win strategy for sustainable development.     

The innovation trajectory of eco-cement in the Netherlands: a co-evolution analysis

In this article, we scrutinize the innovation trajectory of eco-cement in the Netherlands by examining the innovation nexus of eco-cement manufacturers, scientists/researchers, waste producers and policymakers as part of a broader analysis of markets, policy and society, with special attention to standards and regulations. The influence of policy and innovation interactions are substantiated by policy documents, media news, patterns of eco-cement use, and in-depth interviews conducted with relevant eco-cement actors. Our analysis brings forward empirical evidence of how policymakers are involved in the innovation trajectory of eco-cement in multiple ways through building regulations, sector policies, waste policies, and science and innovation policies. Political economy aspects of regulation and innovation in cement industry (e.g. the cooperative approach of waste authorities with regard to re-use of waste, absence of policies to put a price on CO₂ emissions from cement production) are being described, together with the specificities of the cement market. Bans on the disposal of fly ash and sewage sludge resulted in the use of those materials either as a supplementary cementitious material or a fuel. Demand for green cement from is presently growing but meets with several obstacles. Carbon policies are shown to constitute a weak influence. Innovation in eco-cement co-evolved with policy, through mutual dependencies, as a theoretical finding for innovation studies.
