In a generalized quality-ladder growth model, this paper firstly derives the optimal patent breadth and the socially optimal profit-sharing arrangement between patentholders. In this general-equilibrium setting, it identifies and derives a dynamic distortion of markup pricing on capital...

We estimate the effect of four types of education qualifications, as a proxy for human capital and skill levels, on GDP per capita, and compute the average percentage returns. We also test the effect of the product of each proxy of human capital with R&D on GDP per capita. We find that only...

This paper extends the principles of open source software development to a non-industry-specific level by introducing the Open Source Innovation (OSI) model. OSI exhibits main differences to other related models and concepts such as the private-collective model, commons-based peer production,...

We study the product and process innovation choice of firms in which a managerial incentive à la Vickers (1985) is present. Taking a two-stage dynamic game approach, we show that managerial firms are led to over-invest in process innovation, as compared to standard profit-maximising firms,...

We develop a simple estimator for production functions in the presence of endogenous productivity change that allows us to retrieve productivity and its relationship with R&D at the firm level. Our dynamic investment model can be viewed as a generalization of the knowledge capital model...

Multi-product firms dominate production activity in the global economy. There is widespread evidence showing that large corporations improve their efficiency by increasing the scale of their operations; this objective can be realized either by consistently investing in R&D or by expanding the...

Is the patent length an effective policy instrument in stimulating R&D? This paper develops a generalized variety-expanding growth model and then calibrates the model to the aggregate data of the US economy to analyze the effects of extending the patent length. The numerical exercise suggests...

In this paper, we investigate the relationship between private and public investment in R&D. Various models proposed in the literature to take account for several instruments policies as: (subsidies, taxes…) are estimated to verify if private and public R&D spending are complement or...

Although the economy of China has grown very strongly over the last few decades, this spectacular performance has come at the expense of rapid environmental deterioration. Amidst animated debate on the issue of global warming, this study attempts to explore the determinants of CO2 emissions in...

Successful innovation depends on the management of a firm’s knowledge base. This paper empirically investigates the determinants of knowledge regulation. Using a unique survey dataset, the analysis suggests that R&D managers do not leak knowledge randomly, but rather regulate knowledge...
