Robustness of Sovereign Risk Indicators:
There are very high correlations the CCA Risk Indicators and Credit Default Swap Spreads (CDS) & EMBI bond spreads on foreign currency debt.
Highly statistically significant
Note that the Risk Indicators did not use sovereign bond or CDS spreads as an input!
(See IMF Staff Paper 2008 and IMF Working Paper 05/155 for results and robustness tests)

Economy-wide CCA Balance Sheet Models Capture Non-linear Risk Transmission
Note that if asset volatility in CCA sector balance sheets is set to zero:– Implicit put options go to zero,
– Macroeconomic accounting balance sheets and traditional flow-of-funds are the result
– Measurement of (non-linear) risk transmission is not possible using macroeconomic flow or accounting frameworks
Interlinked implicit options result in compound options that exhibit highly non-linear risk transmission, as seen a variety of financial crises

Linking the economy-wide CCA models to macroeconomic models
Ideally, we would like to link the sector CCA models to macro models in order to form an integrated model for the economy.
Leonardo will discuss this in detail for Chile.
I will just highlight the issue in two slides.
