Pros and Cons of Backing Winners in Innovation Policy
In the economics profession there is a fierce debate whether industrial and innovation policy should be targeted to specific sectors or firms. This paper discusses the welfare effects of such targeted policies in a third-market international trade model under imperfect competition. A theoretical case for picking winners through a preferential innovation policy is discussed, which is shown to hold without evoking retaliation from foreign competitors. However, in practice information uncertainties remain a concern. The question whether in this case ‘backing winners’ is a wise policy option depends on the characteristics of the information asymmetries and on the extent the government is able to design selection procedures in a way to minimize the transaction costs that may be caused from the market participants’ opportunistic behavior.Innovation policy; R&D subsidies, strategic trade policy, asymmetric information, spill-over effects

Minimal information for studies of extracellular vesicles (MISEV2023): From basic to advanced approaches
Extracellular vesicles (EVs), through their complex cargo, can reflect the state of their cell of origin and change the functions and phenotypes of other cells. These features indicate strong biomarker and therapeutic potential and have generated broad interest, as evidenced by the steady year-on-year increase in the numbers of scientific publications about EVs. Important advances have been made in EV metrology and in understanding and applying EV biology. However, hurdles remain to realising the potential of EVs in domains ranging from basic biology to clinical applications due to challenges in EV nomenclature, separation from non-vesicular extracellular particles, characterisation and functional studies. To address the challenges and opportunities in this rapidly evolving field, the International Society for Extracellular Vesicles (ISEV) updates its 'Minimal Information for Studies of Extracellular Vesicles', which was first published in 2014 and then in 2018 as MISEV2014 and MISEV2018, respectively. The goal of the current document, MISEV2023, is to provide researchers with an updated snapshot of available approaches and their advantages and limitations for production, separation and characterisation of EVs from multiple sources, including cell culture, body fluids and solid tissues. In addition to presenting the latest state of the art in basic principles of EV research, this document also covers advanced techniques and approaches that are currently expanding the boundaries of the field. MISEV2023 also includes new sections on EV release and uptake and a brief discussion of in vivo approaches to study EVs. Compiling feedback from ISEV expert task forces and more than 1000 researchers, this document conveys the current state of EV research to facilitate robust scientific discoveries and move the field forward even more rapidly
Essays on strategic trade policy
The first chapter considers a two-country two-sector third-market Cournot competition model to show that (i) a non-uniform rearrangement of the initially-uniform R&D subsidy/tax in a way which preserves the net government expenditure, or (ii) a non-uniform combination of R&D subsidies and taxes under initial free trade, increases the aggregate profit of the national firms without affecting other countries and, therefore, improves national and joint welfare of the trading countries. This provides a country with an incentive to create a national champion by treating its firms asymmetrically. The second chapter explains that the arguments of the first chapter remain valid under a variety of extensions including conjectural variations approach to the firms\u27 strategic behavior, asymmetric marginal costs and non-constant returns to scale. Domestic consumption of the oligopoly good and international R&D spill-over effects do not affect the arguments, either. The third chapter considers a two-country two-sector segmented-market Cournot duopoly under various scale economies to show that an intra-industry trade emerges from a reciprocal dumping incentive, and that a protective import tariff under non-constant returns to scale generates ‘intra-market profit shifting and profit creating effects’ and ‘cross-market substitution effects’. The cooperatively optimal tariff is smaller than the non-cooperative tariff but its sign is indeterminate, thus leading to the conclusion that the international efforts towards trade liberalization should be supported, although a managed trade ‘may’ be Pareto-superior to free trade depending on parameters

Pros and Cons of ‘Backing Winners’ in Innovation Policy
In the economics profession there is a fierce debate whether industrial and innovation policy should be targeted to specific sectors or firms. This paper discusses the welfare effects of such targeted policies from the perspective of strategic game theory of the firm. A theoretical case for picking winners through a preferential innovative policy is discussed in a third-market international trade model, which is shown to hold without evoking retaliation from foreign competitors. However, in practice information uncertainties remain a concern. The question whether in this case ‘backing winners’ is a wise policy option depends on the characteristics of the information asymmetries and on the extent the government is able to design selection procedures which minimize the transaction costs that may be caused from the market participants’ opportunistic behavior.Innovation policy, R&D subsidies, strategic trade policy, asymmetric information, spill-over effects
