Due to the limited size of the insurance market, insurance companies usually purchase insurance
from a few reinsurance companies with large differences. At this time, using the Vasicek model to describe the
counterparty credit risk will be inaccurate; besides, the insurance company’s understanding of the counterparty
default threshold distribution is incomplete, which makes it difficult to effectively determine the counterparty
default probability.

Cat bonds & Artificial Neural Networks | An example of reinsurance products’ ...GRATeam
Over the last fifty years, numbers and costs of natural disasters have not ceased to multiply. Given this phenomenon, insurers and reinsurers struggle to cover the associated losses. Consequently, they turned to financial markets in order to obtain new hedging capabilities, by using various types of products, suchas excess of loss contracts (named XL) and cat bonds.
This paper presents a mathematic model allowing to predict the number and the cost of incoming catastrophes. Data used include wind catastrophes affecting the southeast area of the United States and whose damages are worth more than a billion dollars. This model helps to price insurance risk transfer products, such as XL contracts or cat bonds. First a regression relying on neural network methodology is implemented in order to predict the global annual cost of future catastrophes. Then, based on the same methodology, a classification is done in order to allocate these costs to the various catastrophes.
Our models are used to price several contracts included in the reinsurance program of “Heritage Insurance,” so our results help estimate the share of premiums received by the reinsurer. Two calculations methods are applied: the exposure curve and the “burning cost” method.
Ours models are also validated on cat bond products, but this time using a financial method. This method allows to estimate the share of the Expected Excess Return (EER) depending of the Probability of First Loss (PFL) and the Conditional Expected Loss (CEL).

M.R. Carter Behavioral Insights for Index Insurance
2. Behavioral Wake-up Call
Behavioral lab experiments have uncovered a wealth of
evidence that people do not approach risk in accord with
economics’ workhorse theory of “expected utility”
For example, found that demand tripled with ’simple’ contract
reformulation in Peru that should not have mattered from a
standard expected utility perspective
Contract reformulated as a lump sum contract focussed on
capital protection rather than income protection
Seemingly consistent with insights from behavioral economics
(cumulative prospect theory) (see work of Jean Paul Petraud)
So what other insights from behavioral economics may help us
understand design of and demand for agricultural index
insurance
M.R. Carter Behavioral Insights for Index Insurance
3. Outline
Focus here on two areas
Insights from the behavioral economics of ambiguity aversion
Basis risk is big ... but,
Ambiguity aversion makes it bigger
Measure ambiguity aversion & its impact on insurance demand
in Mali
Certain premium & uncertain payouts: Why this matters more
than we think
Insights from work on certain vs. uncertain utility
Preference for certainty & insurance demand in Burkina Faso
Impact of contract formulation on contract demand
M.R. Carter Behavioral Insights for Index Insurance
4. Basis Risk is Big ...
... but its behavioral implications may be bigger
To see this, let’s consider index insurance from the farmer’s
perspective
M.R. Carter Behavioral Insights for Index Insurance
5. Index Insurance as a Compound lottery
Collaborative work with Ghada Elabed
M.R. Carter Behavioral Insights for Index Insurance
6. Index Insurance as a Compound Lottery
Note that if the contract failure probability q2 > 0, index
insurance is a partial insurance
Expected utility theory explanations (EUT): With q2 > 0, the
worst that can happen is worse with insurance than without
(Clarke 2011)
Empirical evidence: people dislike partial insurance even more
than the predictions of expected utility theory
Wakker et al. (1997): people demand more than 20%
reduction in the premium to compensate for q2 = 1%
Let’s look more into this surprising aversion to basis risk when
insurance is a compound lottery
M.R. Carter Behavioral Insights for Index Insurance
7. Aversion to Ambiguity & Compound Lotteries
Long-standing evidence (Ellsberg paradox) that people are
averse to ambiguity & act much more conservatively in its
presence
Similar empirical evidence of a similar reaction to compound
lotteries
Psychologically:
Complexity
If people cannot reduce the lottery, then final probabilities
seem unknown –> akin to ambiguity
Halvey (2007) shows in an experiment a link between
ambiguity aversion and compound risk attitudes
M.R. Carter Behavioral Insights for Index Insurance
8. Modeling Compound Risk Aversion
For the simple (binary) compound lottery structure above,
write:
p ∗v[(1−q1)∗u(a1)+q1 ∗u(a0)]+
(1−p)∗v[(1−q2)∗u(b1)+q2 ∗u(b0)]
where:
Inner utility function u captures attitudes towards “simple”
risk: u ≥ 0, u ≤ 0
Outer function v captures attitudes towards “compound” risk:
v ≥ 0
if v ≤ 0 : compound-risk averse
if v = 0 : compound-risk neutral & compound reduces to
corresponding simple lottery

10. Empirical Measurement of Risk & Compound-risk Aversion
Framed field experiments with 331 cotton farmers in
Bougouni, Mali who were in an area being offered a high
quality/low basis risk contract.
Games were contextualized as cotton insurance and
incentivized (mean earnings 1905 CFA (4 USD))
Game 1: Measured the coefficient of risk aversion through
insurance coverage decision with a simple, zero basis risk
contract
Game 2: Added in basis risk (20%) and then elicited
Willingness to Pay (WTP) to eliminate this basis risk:
Theory says that WTP will be a function of compound-risk
aversion and risk aversion
Combine the findings of Game 1 and Game 2 to derive the
coefficient of compound-risk aversion
M.R. Carter Behavioral Insights for Index Insurance
11. Game 1: Measuring Risk Aversion
Games framed as cotton production with insurance games
Historical yield data of the region of Bougouni
Density of cotton yields discretized into six sections with the
following probabilities (in %): 5, 5, 5, 10, 25 and 50%
M.R. Carter Behavioral Insights for Index Insurance
12. Game 1: Measuring Risk Aversion
Here, farmers can choose between 6 coverage levels of
individual insurance (or to not purchase at all), markup of 20%
u (π) =
π1−r
1−r if r = 1
log(π) if r = 1

3 70 (0.27;0.36)
4 80 (0.36;0.55)
5 100 (0.55;∞)
M.R. Carter Behavioral Insights for Index Insurance
13. Game 2: Measuring Compound Risk Aversion
Added basis risk into simple contract used to measure risk
aversion
Offered farmers a choice between the index contract with basis
risk & the basis risk free contract
Kept the price of index insurance constant
Starting with a really high price for the the basis risk-free
contract, slowly lowered the price to see whether and at what
point the individual will shifted from the index to the basis
risk-free contract
Those that shift at a higher price are more averse to basis risk
Using measured simple risk aversion, can then infer additional
compound risk aversion
M.R. Carter Behavioral Insights for Index Insurance
14. Game 2: Measuring Compound Risk Aversion
57 % of the farmers are compound-risk averse to varying
degrees
Willingness to pay to avoid the secondary lottery of those
individuals who demand index insurance is on average
considerably higher than the predictions of expected utility
theory.
Overall, average willingness to pay to eliminate basis risk is
almost 30% of the price of the index contract
Simulated impact on demand for index insurance (with a 20%
mark-up) by a population that has the risk and compound risk
aversion characteristics of the Malian population:

16. Certain vs. Uncertain Utility
Collaborative work with Elena Serfilippi & Catherine Guirkinger
Andreoni & Sprenger propose a simple way to account for
commonly observed behavioral paradoxes (e.g., Alais paradox):
Assuming constant relative risk aversion, hypothesize that
individuals value certain outcomes according to:
v(x) = xα
whereas they value risky outcomes according to
u(x) = xα−β
where α > β > 0
M.R. Carter Behavioral Insights for Index Insurance
17. Certain vs. Uncertain Utility
Collaborative work with Elena Serfilippi & Catherine Guirkinger
If this ’overvaluation’ of outcomes that are certain is correct
(β > 0), implies that individuals undervalue insurance because
the bad thing (the premium) is certain and hence overvalued
relative to the good thing (payments) which are uncertain and
undervalued
Note that overvaluation is above and beyond what would be
expected based on standard risk aversion
Consistent with farmer complaints in the field about paying
premium in bad years
M.R. Carter Behavioral Insights for Index Insurance
18. Field Experiment in Burkina Faso
Working with 577 farmer participants in the area where we are
working with Allianz, HannoverRe, EcoBank, Sofitex and
PlaNet Guarantee to offer area yield insurance for cotton
farmers, played two incentivized behavioral games:
Measured risk aversion over uncertain outcomes (α) and
extent of certainty preference (β)
Measured willingness to pay for insurance under two randomly
offered alternative, actuarially equivalent contract framings:
Standard framing (certain premium)
Novel framing (premium forgiveness in bad years)
Found that:
One-third of farmers exhibit certainty preference
Average willingness to pay is 10% higher under novel framing
Certainty preference farmers value the alternative framing by
25%

Certainty Pref. (β > 0) 168 29
Others (β < 0) 218 38
Given that about one-third of farmers appear to have a strong
preference for certainty, the key question then becomes if these
farmers are sensitive to contract design and framing
Specifically, will these farmers
undervalue conventionally framed insurance relative to
Expected Utility types
respond positively to an insurance contract in which payment
of the premium is uncertain (rebated)
M.R. Carter Behavioral Insights for Index Insurance
24. Insurance Demand Experiment
An insurance on cotton production is something you buy before you
know your yield. The insurance gives you some money after the
harvest, but only in case of bad yield. Let me explain how the
insurance works.
Frame A
The amount of your savings is 50.000 CFA. You decide to buy an insurance
before you know your yield. The insurance price is 20.000 CFA.You pay the
insurance with your savings. Therefore you remain with 30.000 CFA. In case of
bad yield, the insurance gives you 50.000 CFA. In case of good yield the
insurance gives you 0 CFA.
Frame B
The amount of your savings is 50.000 CFA. You decide to buy an insurance
before you know your yield. The insurance price is 20.00 CFA.You pay the
insurance with your savings, BUT only in case of good yield.Therefore you
remain with 30.000 CFA in case of good yield and 50.000 CFA in case of bad
yield. In case of bad yield the insurance gives you 30.000 CFA. In case of good
yield the insurance gives you 0 CFA.
M.R. Carter Behavioral Insights for Index Insurance
25. Willingness to Pay for insurance
Randomly offered some farmers Frame A, and others Frame B
Under both frames, explore farmer’s willingness to buy
insurance as we slowly decreased the price from a very high
30,000 CFA (3-times the actuarially fair price) to 0 CFA
Price was decreased in 5000 CFA increments
Price at which farmers switches identifies willingness to pay

standard errors, etc.) confirms these findings that Frame B
has a large & significant impact on demand for the 30% of the
population that exhibits a strong preference for certainty

27. Conclusions
Behavioral economics has offered a number of insights on how
people ’really’ behave (as opposed to how economists believe
they behave)
Insights especially rich in the area of behavior in face of risk
Behavioral economic games with West Africa cotton farmers
reveal two things:
1 Basis risk not only lessens value of insurance, but farmers’
ambiguity aversion depresses demand even more than would be
expected (meaning that insurance can have none of its
hypothesized development impacts)
2 Farmers surprisingly overvalue “sure things” relative to unsure
things–writing contracts with unsure premium enhances
farmers willingness to pay for insurance significantly
Given continuing problems of sluggish demand for agricultural
index insurance in many places, these insights suggest
important new ways of designing contracts
