- The central prediction of the Aghion, Bloom, Blundell and Howitt model is an inverted U-shaped relationship between innovation and competition. The model is built on the assumption of a product market and has not yet been tested on the service sector. Using detailed firm-level data on Swedish service-sector firms, we find evidence of an inverse U-shaped relationship for exporting service-sector firms. A further breakdown of innovation expenditures shows that the inverse U-shaped pattern holds for intramural R&D and training, but not for extramural R&D. Finally, the results indicate that as competition increases, small firms tend to seek strategic alliances with competitors, whereas large firms tend to reduce collaboration with competitors. The behavior of large firms can partly be due to their superior capacity to handle innovation projects internally, which will become more important if increased competition results in higher pay-offs to innovation.

Journal article (peer-reviewed)abstract
- Purpose: Parenting programmes are seen as feasible and cost-effective in preventing early behavioural problems in children and adolescents. A number of studies have concluded that such programmes are effective in reducing child problem behaviours and improving the skills and well-being of parents. Nevertheless, less is known about long-term programme effects.Design/methodology/approach: A non meta-analytic discussion.Findings: Long-term evaluations of parenting programmes suffer from a number of methodological weaknesses resulting in an inability to make robust causal inferences about child and parent outcomes in the longer term. The current evidence is favorable but is likely to be biased by methodological weaknesses. There is a need for more studies of greater methodological strength to obtain conclusive evidence that would guide empirical research, practice and policy.Originality/value: The paper discusses weaknesses in long-term evaluations of parenting programmes and highlights concrete future directions toward improving the quality of study design, evaluation and data analysis.
