The Global Risks Alliance (GRA)
The research behind Reinsurance and Catastrophe: the questions it asks, the methods it uses and how evidence is reviewed before it is published.

Reinsurance and Catastrophe · Evidence registerEvidence register, in outline: domain structure with placeholder names and illustrative values, not a record.
Reinsurance and Catastrophe research is the evidence work behind the platform: questions such as reinsurance structures and catastrophe models, answered with extreme value theory and tail risk as well as actuarial mathematics and reviewed before publication. Every result carries an evidence label, from observed to modelled or expert judgement, and missing data is shown as missing, never filled silently.

For professional research, in GRA's spatial-finance reading, the map opens on population density, night lights and true-colour imagery with built-up and settlement extent from NASA GIBS, framed on the Gulf of Mexico coast; every other NASA layer, live feed and forecast waits in the layer list.
The interactive map needs JavaScript; the layer list and sources are below.

Reinsurance and Catastrophe research concerns catastrophe loss, risk transfer and capital. It is written for catastrophe modellers and reinsurance underwriters and brokers' analysts, carries an evidence label on every value and never performs any institution's own analysis of placement or broking.
Results are labelled as observed, officially reported, estimated, modelled, forecast, scenario or expert judgement. Missing data is shown as missing, never filled silently.
Each term as this page uses it. Where a standard-setting body defines the term, the wording follows that body.
| Term | Definition |
|---|---|
| Research integrity | Conduct of research in line with principles of reliability, honesty, respect and accountability, as the European Code of Conduct for Research Integrity sets them out. |
| Evidence label | A tag naming the kind of evidence, such as observed or modelled, that should survive every summary. |
| Reproducibility | Obtaining consistent results using the same data and analysis code as the original study. |
| Stochastic event set | A large simulated catalogue of events, each with a frequency, representing what a peril could produce. |
The bodies and documents this page is read against. Status and editions change; each link goes to the issuing body.
The current service level is R0: information and enquiries. An enquiry receives a reference and names the next step; applications, payments, compute allocations and registrations open only when their team, terms and review capacity exist.
