This paper discusses a model of vertical and horizontal product differentiation within the Dixit-Stiglitz framework of monopolistic competition. Firms compete not only in prices and horizontal attributes of their products, but also in the quality that can be controlled by R&D activities. Based...

The granting of publicly subsidized joint projects has become a popular policy instrument in both Germany and the European Union. However, little is known about how the emerging subsidized network affects the allocation process of future project grants. Employing unique databases containing...

Carbon Capture Utilization and Storage (CCUS) stands as a pivotal technology crucial for achieving the most ambitious climate objectives. Despite its prominent inclusion in energy mix projections, its current deployment falls short of the requisite level. Additionally, uncertainties surrounding...

I develop a model of R&D cooperation with uncertain research outcomes. In this model asymmetric outcomes of R&D competition emerge naturally. Therefore ex-ante and ex-post R&D cooperation can be studied as alternatives for firms. Using this model I compare welfare losses under ex-ante and...

We reconsider the justifications of R&D subsidies by Spencer and Brander (1983) and others by allowing firms to pool R&D investments and license innovations. In equilibrium R&D joint ventures are formed and licensing occurs in a way that eliminates the strategic benefits of R&D investment in the...
