UK Inflation 4.4% in February 2011

CPI annual inflation – the Government’s target measure – was 4.4 per cent in February, up from 4.0 per cent in January.

The largest upward pressures to the change in CPI inflation came from:

ECB to reveal if increased commodity prices or wages dictate rate increase policy

On Thursday this week ECB is expected to be the first of the three leading central banks to raise interest rates by 25 basis-points in its main rate to 1.25 per cent.

The ECB announced at last month’s policy meeting its “strongly vigilant” stance against inflation. Eurostat published its flash estimates where Euro area annual inflation is expected to be 2.6% in March 2011. This is well over the 2% target.

Default Factor Modelling Blueprints from JAM Analytic Bridge Blog (ABBU)

The Default Factors are 'Probability of..' / 'Loss Given ..' etc etc (there are more spohisticated variants and inverts which can be deployed), alot of people find these difficlult to get their heads around (I sympathize, I did too, at the beginning); and then you have to integrate them into a macro-factor model to estimate risk capital (an oversimplification I know).

A Developing issue in Macro-Econometric Modeling: Stress Testing

There is a developing issue in Macro-Econometric Modeling right now. It has been burning for about a year; we at asymptotix have some practical engagement with it which is reflected in our essay called 'Crowding Out 2'. That essay and its related comments simply document our experience at the client coal-face where we naively found ourselves addressing in a commercial engagement a great intellectual challenge of our time, probably way ahead of the academic curve. At a much more global and higher media oriented level this issue is documented in what is known as the Krugman / Ferguson debate or put more crudely (cf Niall Ferguson) the Keynesians versus the Monetarists (or more strictly the Classicists or Neo-Classicists).

BIS - Joint Forum recommends improvements in risk aggregation models

The report suggests improvements to the current modelling techniques used by complex firms to aggregate risks. It also examines supervisory approaches to firms' use of risk aggregation models, particularly in light of the global financial crisis.

 

Mr Tony D'Aloisio, Chairman of the Joint Forum and Chairman of the Australian Securities and Investments Commission, said "This report is essential reading for firms considering ways to make more effective use of risk aggregation methods, and for supervisors wanting to understand firms' use of risk aggregation models to help identify shortcomings in a firm's approach."
