This chapter aims to contribute to the better understanding of R&D by scholars and practitioners. It includes a first section where the concept of innovation is defined and its public good nature and cumulative dimension are analysed. Next, the incentives that firms have to undertake R&D to attain a competitive edge upon rivals are considered. This entails the consideration of both ex ante and ex post incentives to undertake R&D. Since innovation is costly and derives important external effects, cooperation in R&D activities is prominent in several industries where firms enter into research joint ventures, or form research networks. The effect of cooperation is that, under some circumstances, the industry performance is better as compared to full competition. The final section addresses the complementarities and conflicts among the different microeconomic policies (trade, industrial and competition policy) faced by governments when considering the support of R&D activities.

Around the world, competition agencies and academics alike have raised concerns that the existing suite of policy tools and economic theory fail to capture all of the harms that can arise in digital markets. At the same time, other academics and practitioners consider that competition policy and industrial organization is unable to account for many of the benefits that online platforms and digital ecosystems can bring. As a range of new interventions – ranging from strengthened ex-post enforcement tools to new ex-ante regulations – are being proposed, we ask which view is right? Are the business practices observed in digital markets and targeted by these reforms so obviously harmful that they are deserving of a return to form-based prohibitions in place of effects-based analysis? Or does this represent an unhelpful regression, based on a misunderstanding of how these new types of markets function?

Abstract The economics literature on Net Neutrality (NN) has been largely critical of NN regulation on the basis of theoretical findings that NN violations can be both welfare improving and welfare deteriorating, depending on the circumstances of the case in question. Thus, an ex post competition policy approach would be preferable to a strict ex ante prohibition of NN violations. In contrast, the current paper argues that NN regulation is largely ineffective, in particular, when it comes to the prohibition of fast lanes and other quality of service (QoS) differentiations, and to a lesser extent, when it comes to the zero price rule. NN regulation is only effective in preventing the blocking of specific content and in preventing the favoring of ISP owned content and in preventing some price discriminations. These are also areas where NN regulations are more likely to be welfare-enhancing. Where they are ineffective, NN regulations are likely to create inefficiencies through the cost and allocative inefficiencies caused by NN bypass. The paper ends with a call for theoretical and empirical economic analyses of NN circumvention techniques.

This chapter elaborates the operation of criminal liability by closely considering efficient crimes and the law’s stance toward them, shows how its commitment to proportional punishment prevents the probability scaling that systemically efficient allocation requires, and discusses the procedures that determine the actual liability prices imposed on offenders. Efficient crimes are effectively encouraged by proportional punishment, and their nature and implications are examined. But proportional punishment precludes probability scaling, and induces far more than the systemically efficient number of crimes. Liability prices that match the specific costs imposed by the offender at bar are sought through a two-stage procedure of legislative determination of punishment ranges ex ante and judicial determination of exact prices ex post, which creates a dilemma: whether to price crimes accurately in the past or deter them accurately in the future. An illustrative Supreme Court case bringing all these themes together is discussed in conclusion.
