Conflict in times of COVID-19Book chapterNicolas Berman, Mathieu Couttenier, Nathalie Monnet et Rohit Ticku, Simeon Djankov et Ugo Panizza (Eds.), 2020-06, pp. 147-156, CEPR Press, 2020

This chapter discusses the potential impacts of the spread of COVID-19, and the restriction policies that it has triggered in many countries, on conflict incidence worldwide. Based on anecdotal evidence and recent research, we argue that imposing nation-wide shutdown policies diminishes conflict incidence on average, but that this conflict reduction may be short-lived and highly heterogeneous across countries. In particular, conflict does not appear to decline in poor, fractionalised countries. Evidence points to two potential ways in which COVID-related restriction policies may increase conflict: losses in income and magnified ethnic and religious tensions leading to scapegoating of minorities.

Steuart, Hegel, Chamley: A Case Upon the Nature of ‘Influence’Book chapterGilles Campagnolo, J. M. Menudo (Eds.), 2020, pp. 214-240, Routledge, 2020

From July 25 to 31, 1796, Georg Wilhelm Friedrich Hegel, then working as a private tutor for the aristocracy in Bern, took a mountain hike in the neighbouring Alps. Hegel travelled from Thoune to Altdorg via the Jungfrau and the Uri, a land of glaciers. As Hegel began studying economics for good, the query would reappear: in his reading of Sir James Steuart’s Inquiry into the Principles of Political economy, Hegel would make his first step into economic theorizing. In Frankfurt, Hegel was not yet a tenured Gymnasium professor. He was again a private tutor, experiencing hardships of a salaried life – though in wealthy families. Paul Chamley selected excerpts of interest based on his first assessment of the thesis that there surely exists a solid ‘system of political economy’ by Hegel. He assumed it rather than he found it as a result of his comparative study.

Manufacturing Doubt: How Firms Exploit Scientific Uncertainty to Shape RegulationBook chapterYann Bramoullé et Caroline Orset, Matthias Ruth (Eds.), 2020, pp. 215-230, Edward Elgar Publishing, 2020

Many regulations with first-order economic and environmental consequences have to be adopted under significant scientific uncertainty. Examples include tobacco regulations in the second half of the 20th century, climate change regulations and current regulations on pesticides and neonicotinoid insecticides. Firms and industries have proved adept at exploiting such scientific uncertainty to shape and delay regulation. The main strategies documented include: hiring and funding dissenting scientists, producing and publicizing favorable scientific findings, ghostwriting, funding diversion research, conducting large-scale science-denying communication campaigns, and placing experts on advisory and regulatory panels while generally concealing involvement. In many cases, special interests have thus deliberately manufactured doubt and these dishonest tactics have had large welfare consequences.
Largely and unduly neglected by economists, these doubt-manufacturing strategies should now be addressed by the field. Here, we first present a simple theoretical framework providing a useful starting point for considering these issues. The government is benevolent but populist and maximizes social welfare as perceived by citizens. The industry can produce costly reports showing that its activity is not harmful, and citizens are unaware of the industry’s miscommunication. This framework raises important new questions, such as how industry miscommunication and citizens’ beliefs are related to scientific uncertainty. It also sheds new light on old questions, such as the choice of policy instrument to regulate pollution. We subsequently outline a tentative roadmap for future research, highlighting critical issues in need of more investigation.
