The study examines Pareto optimal risk sharing in insurance with consumption substitution and saving in a two-period model. It confirms the robustness of classical risk-sharing results, even with recursive utility, and explores the link between consumption elasticity and saving. Precautionary savings and partial separation of risk aversion are demonstrated.
This paper introduces CATALIST, a detailed sectoral model of the Spanish economy, to assess transitional risks from climate policies like carbon pricing. It reveals varied sectoral impacts, potential financial stability risks, and growth opportunities via smart tax revenue use, offering a versatile tool for policy and scenario analysis.
Insurance decisions range from trivial to significant, accumulating impact over time. Intuition can mislead, especially when premiums rise due to risk. Key factors include hazard size, wealth, risk aversion, and insurer margins. Greater transparency in insurance margins can help families make informed choices, improving financial well-being and societal welfare.

The EU's Digital Services Act and Corporate Sustainability Due Diligence Directive both require large companies to implement internal risk management systems. This approach, however, strengthens corporate power by minimizing regulatory costs, reinforcing technocratic solutions, and enabling corporations to evade responsibility for negative social impacts by framing them as external risks. This procedural focus hinders effective enforcement.
Natural disasters drive insurance premium increases in affected areas for three years and cause delayed, smaller rises in unaffected areas. Insurers also adjust rejection rates, particularly in low-income regions. Financial constraints influence cost distribution, raising concerns about equity and affordability as climate risks grow and insurers adapt pricing strategies.
The insurance sector faces pressure from rising catastrophic risks, leading to higher premiums and policy non-renewals. This paper proposes an arbitrage-free method for pricing catastrophe reinsurance using the compound dynamic contagion process and Esscher transform. The findings help insurers assess liabilities amid emerging risks like climate change, cyberattacks, and pandemics.
Significant risk transfer (SRT) securitization is increasingly used by major EU banks for risk and capital management. It provides flexible, reasonably priced capital, improving balance sheets and capital ratios. Supervisors assess risk transfer for capital relief. The SRT market has grown substantially and is a key tool for European banks.
The EU AI Act's implementation begins after a 3-year legislative journey, requiring national authorities to clarify and enforce it. This policy brief outlines Belgium's tasks under the Act, including scope application, exemptions, and the designation of competent authorities to manage AI-related responsibilities.
This paper introduces "co-opetition" (combining competition and cooperation) to reinsurance risk-sharing. A two-layer game-theoretic framework models insurer-reinsurer contracting and price competition (Stackelberg-Nash), followed by collaborative risk-sharing. The model, using mean-variance preferences, yields explicit equilibrium results, demonstrating the feasibility of analyzing complex reinsurance market dynamics. Future research could explore different preferences, premium principles, and market structures.
This paper explores continuous-time mean-variance reinsurance with heterogeneous beliefs, a novel approach. It finds complex optimal contracts, beyond standard types, and proves their uniqueness. Specific forms emerge under different belief assumptions. Critically, it shows this model better reflects real-world insurer decisions than models ignoring belief differences.
