GRA · Actuarial and Quantitative Risk

Spatial financeWhere capital meets hazard, exposure and transition

توێژینەوە و بەڵگە

Actuarial and Quantitative Risk research asks how to estimate tails honestly with short and changing data, how to represent dependence between perils and regions, how climate should condition pricing, and how models should be validated when the past is a biased sample.

02پرسیارەکان

What the research asks.

  1. 01

    Loss distributions

    Frequency, severity and aggregate loss, and how tails are estimated.

  2. 02

    Extreme value methods

    Tail estimation for hazards, markets and operational losses.

  3. 03

    Climate-adjusted pricing questions

    How non-stationary hazard changes pricing assumptions.

  4. 04

    Credibility and sparse data

    Working where loss history is short or missing.

  5. 05

    Dependence and correlation

    Copulas, contagion and why correlations break in stress.

  6. 06

    Capital and solvency models

    Internal models, standard formulas and their assumptions.

Every result keeps its label.

Results are labelled as observed, published statistics, estimated, modelled, forecast, scenario or expert judgement. Missing data is shown as missing, never filled silently.
