Despite the comprehensive previous research on different aspects of inventions and externalities spanning both the micro- and macrolevels, no prior studies have, to our knowledge, examined the relationship between the commercialization strategies of inventions/patents and social knowledge spillovers. To bridge this gap in the literature, we examine how such spillovers, measured as forward citations, covary with four commercialization modes: (1) setting up a new firm, (2) commercialization within an existing firm where the inventor either is employed or (3) has an ownership stake, and (4) licensing/selling patents to other firms. Alternatively, an inventor may refrain from commercialization. Utilizing unique survey data on patents owned by small- and medium-sized enterprises and individuals, we provide evidence that commercialization through licensing/selling is the most efficient way of generating knowledge diffusion. We also find some support for new ventures being an important source of knowledge spillovers.

The challenges of combatting climate change are unprecedented and now very urgent. Current approaches are not working fast enough. This paper, and this journal issue, conceive of the challenge as one of non-marginal structural and institutional change. Several different conceptual frameworks and pluralist theories are considered, emanating from complexity theory, economics, natural sciences, political economy, and strategy. These are deployed to identify potential accelerators, including synergies between climate action and other key political issues, and beneficial non-linear dynamics such as shifts in consumer preferences and technology learning curves. The delays in action also mean that removing carbon dioxide from the atmosphere is now necessary, and even unconventional geoengineering approaches may need to be considered. A pluralist and practical approach to climate action, accounting for different institutional and social contexts across countries, is argued to be required to accelerate action.

We introduce a new measure of human capital, defined as employees' former involvement in entrepreneurship. Such entrepreneurial human capital (EHC) complements traditional human capital measures accumulated through work experience and education. Using detailed longitudinal register data, we track the previous years of entrepreneurial experience for the population of employees in Swedish private sector firms. We provide evidence that higher EHC among employees is associated with significantly higher levels of firm productivity. The baseline result implies that a 10 % increase in employees being former entrepreneurs increases firm-level productivity by 3.9 %. Additionally, we provide evidence that heterogeneity in employees' previous entrepreneurial experience (e.g., the reason for entering and exiting entrepreneurship, type of venture, length of entrepreneurial experiences, and relatedness of technology) influences the impact of EHC on productivity. The results are shown to be robust to various estimation techniques, alternative definitions of EHC, and other performance measures.

This comprehensive Handbook presents thoughtful analysis on how regulations can impact innovation within a number of fields and markets, and provides a greater understanding of regulatory complexity and the challenging task it presents for future research. The Handbook of Innovation and Regulation embraces some of the key policy areas such as the regulation of markets, critical sectors, and global and regional aspects, focussing particularly on those regulations which target innovation. Reviewing these often interconnected policy areas in terms of both macroeconomic and microeconomic issues, this Handbook expertly studies how regulations in differing fields can affect innovative activities. By placing innovation centre stage, the contributors emphasise the direct and indirect effects of imposed regulations. Further, they illustrate the critically important overall impact of innovation to make firms competitive, promote economic growth and increase societal welfare. Addressing research and policy challenges, this Handbook would be an excellent resource for academics in regulatory economics, innovation and entrepreneurship, international trade, regional economics as well as environment and digitisation and policymakers in both national and international organisations.

During the first quarter of 2020, the global economy was rapidly hit by a pandemic which led to state-wide lockdowns and the worst economic crisis since the World War II. Both the supply and the demand sides of economies were severely affected, followed by a dramatic dip in global GDP. As a response, policymakers introduced an unprecedented number of interventions to back up employees, firms, and industries to counteract the collapsing markets. Our main objective is to explore how these fundamental policy interventions are likely to influence the future potential and functioning of markets. Historically swings in the pendulum favoring either market-based solutions or more regulated public sectors have coincided with disruptive crises. The overall question is what will happen during post-COVID-19, will governments withdraw their crisis policies and how will a possible retreat be organized? Are we entering an era of permanently increased governmental interventions? More precisely, we identify three specific threats to the market-oriented economy: the extension and development of governmental expenditures, protectionistic measures, and the level of state aid and the degree of competition at markets. We are particularly interested in the effect of the COVID-19 measures, and their possible extension, on Schumpeterian dynamics, both in terms of entry and exits (Schumpeter I) and how the position of large firms will be affected (Schumpeter II).
