Title: The dynamic interactions of hate, violence and economic well-being Authors: Appelbaum, Elie Abstract: This paper provides a simple dynamic model that explores the interdependence and dynamic properties of hate, violence and economic well-being. It shows that a time-dependent economic growth process that affects the evolution of hate can yield a long-run steady state, but this steady state will not be free of hate and violence. Moreover, we show that better (long-run) economic conditions do not necessarily result in lower equilibrium levels of hate and violence. We also show that, under reasonable conditions, cycles of hate and violence cannot occur. Consequently, the dynamic properties of hate and violence alone cannot result in cyclical (net) economic well-being patterns. While stable and unstable equilibria are possible, the most likely equilibrium is a saddle point. Given its nature, we can view the paper as an example of a formal model for the ideas of the "dynamical system" literature in psychology. Although the paper does not discuss policy decisions, it identifies potential instruments for policymakers to achieve better steady states and greater stability. Finally, we provide two fully nonlinear multi-dimensional numerical examples (in an appendix) to demonstrate the implications of various psychological attributes, sensitivity to economic conditions, externalities, violence and small equilibria perturbations regarding the nature of the steady state and stability of the equilibria.

Title: University-government-foundation collaboration on arms control and security policy in the United States from Truman to Trump Authors: Evangelista, Matthew Abstract: The relationship between the United States government, private foundations, and university-based researchers working on peace and security policy has evolved over time. Since the end of World War II we can identify four main phases: (1) secret government funding into the 1960s; (2) a Golden Age of foundation support in the 1970s and 1980s; (3) decline of support after the end of the Cold War; (4) a revival of interest in the wake of the terrorist attacks of 11 September 2001, with government funding through the Pentagon's Minerva grants and new foundation support representing an unusual alliance between leftwing and realist critics of US military expansionism on the one hand and rightwing neoisolationists on the other. To illustrate these phases, the article draws, among others, on documents from Cornell and Harvard universities and materials from the Ford, MacArthur, and Koch foundations. It represents an idiosyncratic account, based in part on the author's experiences.

Title: Unveiling the impacts of geopolitical risk on the transition to the decentralized financial landscape Authors: Kyriazēs, Nikos K.; Economou, Emmanouil Marios L. Abstract: This paper examines the dynamic interplay between the global geopolitical risk and eleven decentralized finance (DeFi) digital currencies during the inflationary burden caused by the Russia-Ukraine war episodes. Daily data spanning from 13 October 2021 to 29 October 2024 and the innovative Quantile-Vector Autoregressive (Q-VAR) methodology are employed for estimating the pairwise, joint and network linkages at the lower, middle and upper quantiles. High levels of geopolitical risk are more connected with bull markets of the DeFi assets and new war episodes strengthen this relation. Geopolitical tensions combined with high inflation lead to the GPR becoming major determinant of DeFi markets so contributing to the transition to the digital decentralized cashless financial system. Maker is the leading DeFi asset in this transition and constitutes a promising successor of fiat currencies that suffer from devaluation generated by conflicts.

Title: Online interest in radical Islam and terrorist attacks Authors: Nicolini, Marcella; Sabatini, Fabio; Fantazzini, Dean Abstract: This study investigates the link between terrorist attacks and public interest in radical Islam and violent extremism, using monthly data from 150 countries between 2004 and 2015. Employing a dynamic common correlated effects (DCCE) estimator to account for potential cross-country correlations, our analysis reveals that attacks carried out in the name of Islam significantly drive online searches for sensitive keywords. Specifically, terms suggesting violent actions, such as "beheadings," and explicitly jihad-related terms show stronger correlations, indicating heightened interest in the terrorists' actions and messages. Our findings suggest that terrorist attacks not only occur in areas where public attention to terrorism is already heightened but also intensify interest in violent extremism within those regions. This amplification may contribute to terrorists' objectives by increasing the public visibility they seek.
