We present a continuous-time generalization of the seminal R&D model of d’Aspremont and Jacquemin ('American Economic Review', 1988) to examine the trade-off between the benefits of allowing firms to cooperate in R&D and the corresponding increased potential for product market collusion. We...

This paper examines the acceptance of burden sharing rules that refer to the costs of the Ger-man energy transition, which is one of the most challenging and disputed national climate and energy policy measures. Based on data from a comprehensive survey of more than 2,200 citi-zens, the...

The EU emissions trading system (ETS) and the promotion of renewable energy are overlapping regulations. Although the resulting early development of renewables is associated with several advantages such an overlap may violate the path of optimal abatement. Subsidies may cause a too high share of...

The Green Paradox states that, in the absence of a tax on CO2 emissions, subsidizing a renewable backstop such as solar or wind energy brings forward the date at which fossil fuels become exhausted and consequently global warming is aggravated. We shed light on this issue by solving a model of...

Halal certification of financials product may reduce transaction costs for its buyers when it provides a trusted standard for investors that seek to comply with Islamic law. However, we show that in practice it takes considerable amounts of time (20 days) and money (USD 122,000) to obtain a...

We describe how product liability interacts with regulatory product approval in influencing a firm's incentives to acquire information about product risk, using a very parsimonious model. The firm may have insufficient information acquisition incentives when it is not fully liable for the harm...

Using a simple OLG model where the research output of one generation provides inputs for the next, the paper explains how quality standards can become established in scientific competition. Researchers seek status, which they get if their results are used by the next generation. Quality is...

This paper argues that growth theory needs a more general notion of “regularity” than that of exponential growth. We suggest that paths along which the rate of decline of the growth rate is proportional to the growth rate itself deserve attention. This opens up for considering a richer set...

The relevant competitors in regard to innovation might, but not necessarily do, correspond to the identified competitors on actual product markets. Hence, the conventional analysis of product markets, in order to assess the potential anticompetitive effects of mergers, is insufficient to capture...

Innovation and technological change are central to the quest for regional development. In the globally-connected knowledge-driven economy, the relevance of agglomeration forces that rely on proximity continues to increase, paradoxically despite declining real costs of information, communication...
