Different dimensions of knowledge in cooperative R&D projects of university scientists

An increasing speed of new knowledge generation and a growing specialization of individuals in specific fields make cooperative R&D projects indispensable to stay abreast of the latest technological developments. However, studies targeting this field of research have almost exclusively focused on industrial cooperation projects, neglecting the importance of academic R&D collaboration.We attempt to address this research gap by investigating completed R&D cooperation projects of 376 German professors of the chemical and biological sciences. Based on their evaluation, we can distinguish between successful and less successful projects mainly involving explicit or tacit knowledge. We further characterize these groups by identifying significant group differences regarding trust, the interdependency between partners, the frequency of communication and the closeness of partners. Overall, our study presents new empirical evidence that the codification of knowledge plays an important role for the success of cooperative R&D projects.     

Integration, agglomeration and welfare

This paper studies the social desirability of agglomeration, and the efficiency arguments for policy intervention in a simple, analytically tractable new economic geography model. The location pattern emerging as market equilibrium is ‘bubble-shaped’, i.e. it features dispersion both at high and low trade costs and stable equilibria with partial and full agglomeration for intermediate levels of trade costs. We show that the market equilibrium is characterized by over-agglomeration for high trade costs and under-agglomeration for low trade costs, and we work out analytically that a net pecuniary externality is the underlying cause of this market failure. One particularly noteworthy result is that the net pecuniary externality is positive at high levels of trade freeness. However, there is no market under-agglomeration unless this positive net pecuniary externality interacts with an additional congestion force originating in the (per se efficient) competitive housing market.     

Book reviews

Recent regulatory initiatives stress that an independent oversight board, rather than the management board, should assume the role of auditors' client. In an experiment, we test whether the type of client affects auditors' independence. Unique features of the German institutional setting enable us to realistically vary the type of auditors' client as our treatment variable: we portray the client either as the management preferring aggressive accounting or the oversight board preferring conservative accounting. We measure auditors' perceived client retention incentives and accountability pressure in a post-experiment questionnaire to capture potential threats to independence. We find that the type of auditors' client affects auditors' behaviour contingent on the degree of the perceived threats to independence. Our findings imply that both client retention incentives and accountability pressure represent distinctive threats to auditors' independence and that the effectiveness of an oversight board in enhancing auditors' independence depends on the underlying threat.     

Optimal delegation choices in the presence of an incongruent performance measure and double moral hazard

An owner‐manager can delegate two tasks to an agent. A time constraint prevents him from completing both tasks at first‐best levels. He can (a) perform both tasks personally to the extent possible, (b) delegate one task to an agent, or (c) delegate both tasks. Agency costs arise from a congruity problem, a double moral hazard problem, and a risk and incentive trade‐off. Delegation becomes more favorable the stronger the time constraint. Once delegation is preferred, the optimal extent of delegation depends on the relation of sensitivity to productivity ratios in both tasks. Agency costs not necessarily increase in delegation level.     

Financial liberalization and the relationship-specificity of exports

We investigate the causal impact of equity market liberalizations on sectoral export performance across 91 countries (1980–1997). The increased availability of external finance has boosted trade of industries that intensively use relationship-specific inputs, and lowered exports of industries using standardized inputs.     

Wage Rigidity, Monetary Integration and Fiscal Stabilization in Europe

Flexibility in fiscal policy is a necessary ingredient in a policy package for EMU. Even with strong endogenous shock absorbers, such as real wage flexibility, fiscal policy can speed up the stabilization process in response to demand shocks. If real wages are rigid, as they typically are in Europe, fiscal policy cannot remove the adverse effects of asymmetric supply shocks, but it can successfully limit the divergence between member states. Monetary flexibility, a possible option in the run-up to EMU, cannot completely make up for the stabilization function of fiscal policy.     

Industrial services, product innovations, and firm profitability: A multiple-group latent growth curve analysis

Manufacturers in many industries seek service-led growth beyond their product core. Yet research on the link between service revenue growth and firm profitability is still at an early stage. To shed further light on this complex relationship, we report the results of a longitudinal study based on panel data of 414 companies in the German mechanical engineering industry collected over a five-year period. Employing latent growth curve modeling and using multiple group analysis, the study provides empirical evidence for the causality between service infusion strategies and manufacturers' profit trajectories. The results also reveal differential effects of service categories and the moderating role of manufacturers' product innovation efforts. For companies with high product innovation activity, services supporting the product (SSPs) directly increase firm profitability, while services supporting the clients' actions (SSCs) do not display any link with long-term profitability. Conversely, for companies with low product innovation activity, SSCs have a significant, positive effect on firm profitability, while SSPs have only an indirect effect. In sum, our findings caution managers that service offerings do not automatically improve company profits. Manufacturers must carefully consider the fit between their service offerings and product innovation activities to grow bottom line results.     

Same Same But Different: Dialects and Trade

Language is a strong and robust determinant of international trade patterns: Countries sharing a common language trade significantly more with each other than countries using different languages, holding other factors constant. In this article we present the first analysis of the effect of language on trade in an intra‐national context. Analyzing unique data for a single‐language country, Germany, we find that similarities in the local dialect have a significantly positive impact on regional trade. We interpret this finding as evidence for the trade‐promoting effect of culture, because linguistic similarities likely reflect cultural ties across regions, rather than lower costs of communication or similar institutions.
