Innovation management in service firms: a research agenda

This article suggests an agenda for further research on innovation management in service firms. It investigates differences and similarities between issues identified by previous academic research and issues brought up by practitioners within the area of innovation management in service firms. The results show that there are some major differences; for instance, researchers stress a need for formalized processes for development work, while practitioners focus on facilitating innovation in everyday operations. The main conclusion is that in order to bridge the gap between research and practice we would encourage further research on innovation in service firms to (1) conduct micro studies of innovation work, (2) view innovation in the context of everyday operations and (3) focus on co-workers’ innovative potential.     

Perceived risk and the earthquake insurance purchase decision: a commentary on a paper by Lennart Sjöberg

Sjöberg in his 1994 report entitled 'Perceived risk vs. demand for risk reduction' has argued that 'risk perception' involves two separable components: the probability that an event will occur and the consequences of this event. Based on three empirical studies, Sjöberg concluded that one of these two factors is far more important than the other: that the perceived severity of consequences is a better predictor of demand for mitigation than the perceived probability of harm or risk. This paper focuses on the second of the three reported studies involving the adoption of home insurance in Sweden. The empirical analysis reported here, based on survey research in California, supports the conclusion that perceived probability of occurrence continues to be an important factor in the decision to purchase voluntary hazards insurance.     

Exit and Survival in a Concentrating Industry: The Case of Daily Newspapers in the Netherlands

This paper studies the effects of aggregate, industry-, and firm-specific factors on the exit hazard rates in the market for daily newspapers in the Netherlands from 1950 to 1996. We present a brief overview of the exit literature. On the basis of the existing empirical evidence, we decided to specify and estimate exponential and piecewise constant hazard rate models. We find that exit hazard rates of daily newspapers depend on the circulation size, ownership, and number of incumbents. Moreover, the effects are time-dependent. We do not find any significant effect of macroeconomic factors.     

Quo Vadis MRIO? Methodological, data and institutional requirements for multi-region input-output analysis

In order to understand wider sustainability impacts of consumption and to successfully promote and implement sustainable consumption and production policies, there is a need to capture the whole life-cycle impact of products and services across international supply chains. Multi-region input-output (MRIO) databases are a well described and suitable foundation for global sustainability analyses addressing a wide range of policy and research questions. In this paper we reflect on the reasons for the recent boom in MRIO compilation, summarise the current state of development and discuss future options for MRIO analysis. We list in detail the requirements for efficient and effective MRIO research and propose systemic and institutional changes. We deliberately try to go beyond existing ambitions for MRIO compilation and thus intend to stimulate discussion and to lay out the options for the future of MRIO research.     

Large sample estimation and testing procedures for dynamic equation systems

Joint two-step estimation procedures which have the same asymptotic properties as the maximum likelihood (ML) estimator are developed for the final equation, transfer function and structural form of a multivariate dynamic model with normally distributed vector-moving average errors. The ML estimator under fixed and known initial values is obtained by iterating the procedure until convergence. The asymptotic distribution of the two-step estimators is used to construct large sample testing procedures for the different forms of the model.     

Banking and Debt Crises in Europe: The Dangerous Liaisons?

The potential mutation of the Sub-Prime banking crisis into a sovereign debt one in Euro area countries is investigated. After reviewing the criteria used to measure the debt vulnerability, the balance sheet approach is presented in order to illustrate the potential connections between these two types of crises. A graphical analysis yields evidence that at the end 2009 the probability of observing a Euro area country defaulting is less likely than six month before. Nevertheless, the serious threats, which concern Greece and Ireland, do not permit us to exclude the occurrence of a contagious, or self-fulfilling, sovereign debt or currency crises in Euro area in the future.     

Cointegration Testing in Panels with Common Factors*

Panel unit‐root and no‐cointegration tests that rely on cross‐sectional independence of the panel unit experience severe size distortions when this assumption is violated, as has, for example, been shown by Banerjee, Marcellino and Osbat [Econometrics Journal (2004), Vol. 7, pp. 322–340; Empirical Economics (2005), Vol. 30, pp. 77–91] via Monte Carlo simulations. Several studies have recently addressed this issue for panel unit‐root tests using a common factor structure to model the cross‐sectional dependence, but not much work has been done yet for panel no‐cointegration tests. This paper proposes a model for panel no‐cointegration using an unobserved common factor structure, following the study by Bai and Ng [Econometrica (2004), Vol. 72, pp. 1127–1177] for panel unit roots. We distinguish two important cases: (i) the case when the non‐stationarity in the data is driven by a reduced number of common stochastic trends, and (ii) the case where we have common and idiosyncratic stochastic trends present in the data. We discuss the homogeneity restrictions on the cointegrating vectors resulting from the presence of common factor cointegration. Furthermore, we study the asymptotic behaviour of some existing residual‐based panel no‐cointegration tests, as suggested by Kao [Journal of Econometrics (1999), Vol. 90, pp. 1–44] and Pedroni [Econometric Theory (2004a), Vol. 20, pp. 597–625]. Under the data‐generating processes (DGP) used, the test statistics are no longer asymptotically normal, and convergence occurs at rate T rather than as for independent panels. We then examine the possibilities of testing for various forms of no‐cointegration by extracting the common factors and individual components from the observed data directly and then testing for no‐cointegration using residual‐based panel tests applied to the defactored data.
