Humanitarian response to hurricane disasters: Coordinating flood‐risk mitigation with fundraising and relief operations

To alleviate flooding, caused by hurricanes, governments build structural barriers called levees. In addition, relief providers such as the nongovernmental organizations and charities raise funds, and procure and deliver supplies (food, water, and medicines) for humanitarian relief. The strategy for managing disasters must, therefore, weigh the costs and benefits of building levees as well as procuring and delivering supplies. We use a three‐stage decision making framework to study how the investment in levee capacity can be integrated with supply procurements, fundraising, and rapid response. One of our major findings is that a large fundraising cost discourages postdisaster funding, implying relatively large investments in levee and prepositioned supplies. That notwithstanding, a large social value (of saving life) can tilt the balance in favor of postdisaster funding. If the levee capacity increases, funding for predisaster procurement is reduced without affecting postdisaster funding. For a sufficiently large increase in capacity, however, postdisaster response becomes superfluous. We also find that hurricane uncertainty motivates levees with large capacity. In contrast, levee‐failures motivate levees with small capacity.     

Prospect theory and foreign policy decision-making: Underexposed issues,advancements, and ways forward

How much mileage can we get out of prospect theory to explain foreign policy decision-making? To answer this question, we first argue that risk as outcome uncertainty is the appropriate definition in prospect-theoretical applications. Then, we indicate that probability weighting—a crucial component of prospect theory—is typically ignored in such applications. We argue why this is problematic and suggest how to move forward. Next, we discuss how to establish the reference point in the face of outcomes in multiple dimensions, as is typically the case in foreign policy decision-making. Finally, we discuss what we have learnt regarding prospect theory’s scope conditions and the differences across individuals in the theory’s applicability. Overall, our contribution lies in identifying several underexposed or neglected issues (e.g., the definition of risk and probability weighting), in examining the advancements regarding prospect theory’s scope conditions, and in discussing avenues for further research.     

The continuing resonance of the war as risk management perspective for understanding military interventions

In the late 1990s and 2000s, a slew of books and journal articles proposed that a nexus between risk management and warfare was emerging. This article argues that risk management ideas continue to shape recent campaigns against Libya, Islamic State, Syria, and the war on terror from Niger, Yemen to Somalia. It uses existing literature on risk and warfare to examine four key aspects of contemporary interventions. First, the article evaluates the overall strategic context as security concerns shift from terrorism toward renewed great power competition. Second, it re-assesses the risk calculus for military action through the language and grammar of risk invoked by politicians. Third and fourth, it addresses the continuing reliance on air power and the managerial ethos of military operations as important features of war as risk management.
