A review of the basic theory of optimal open-source software contributions points to three key factors affecting the decision to contribute to the open-source development process: non-pecuniary benefits, future expected monetary returns, and open-source licence type. This paper argues that...

We study the evolution of sectoral employment and labor cost in eleven European countries in the last two decades. Our statistical approach consists in decomposing for country, industry and temporal effects. Virtual economies are constructed by filtering country effects. We find that sectoral...

We analyze the implications for the dynamics of capitalaccumulation of market power and endogenous demand elasticities, in anenvironment in which the latter are affected by the number of competitorsin each industry. In equilibrium the interest rate increases as capitalaccumulates, even though...

There is a wide literature on the dynamic adjustment of employment and its relationship with the business cycle. Our aim is to propose a statistical model that offers a congruent representation of post-war UK labour market. We use a cointegrated vector autoregressive Markov-switching model where...

Background: Current human resources planning models in nursing are unreliable and ineffective as they consider volumes, but ignore effects on quality in patient care. The project RN4CAST aims innovative forecasting methods by addressing not only volumes, but quality of nursing staff as well as...

Interstate Highway and Industrial Clustering Investment in highway construction is usually justified by the belief that it will contribute to economic growth via a variety of mechanisms: market expansion, regional specialization, acceleration of industrial clusters (agglomeration) and...

Objective. To assess the effectiveness of interventions in community and workplace settings to reduce sickness absence and job loss in workers with musculoskeletal disorders (MSDs). Methods. Relevant randomized controlled trials (RCTs) and cohort studies, published since 1990, were identified by...

This dissertation applies the theory of technology accumulation to explain the internationalisation of foreign and West German multinational enterprises (MNEs) into East Germany. This theory shifts the focus from technology transfer to the international diffusion of innovation within the MNE. It...

Policymakers are increasingly interested (see NESTA 2007a, DIUS 2008) in what has been called User-Led (von Hippel 1988), Open (Chesborough 2003) and Democratic (von Hippel 2005) innovation as a driver for profit and/or social well-being. This paper argues that user-led innovation is a composite...

This thesis is concerned with the organisation of innovation in the interaction between multinational companies and host-country innovation systems. It proposes a framework for characterising the decentralised governance of innovation projects in sectors and identifying emerging organisational...
