Liquidity Risk The Interbank Market and Game Theory

Interbank markets may fail to allocate liquidity efficiently due to: asymmetric information about the quality of banks’ assets, banks’ free-riding on each other’s liquidity or on central bank liquidity; or as a consequence of predatory behaviour forcing ineffiient liquidation of bank assets. These are the (reasonably) well understood features of the "Game Theory" of the global interbank market.

It is becoming generally understood (particulalry in banking software development) that… Continue

Structured Credit Instruments (Toxic Assets) Theory and Practice of Quantitative Fair Value

We at asymptotix have been publishing again!

This is all part of the 'Theory Forge' (or theoretical framework) which I have been initiating recently. Our publications work (we think) by explaining more fully our theoretical point of view & our specific approach to quantitative analytics in risk management and finance. The content is mostly taken from the higher level theoretical background with which we approach specific client engagements.

Our new publications are two… Continue

Think Top Down, Build Bottom Up

by Kesavan,H.

When an organization kick-starts a Business Intelligence (BI) initiative, it should start TOP-DOWN by identifying a business sponsor first. This business sponsor is none other than the CEO himself. The drive for such an initiative has to come from the top. An IT head such as a CIO sponsoring the initiative may not take it very far and most often the initiative might end up getting abandoned or the BI system, even if implemented, might not find any… Continue

Market research in a recession

Ironically, a recession that is making consumer understanding even more necessary has also led to a reduction in market research budgets and shrinking head counts. There’s less money and fewer people to conduct research at a time when it’s more important than ever! more...

Is the Recession Going to End This Year?

According to Bernanke, there is a possibility that the recession could end in 2009. Additionally, over the weekend the G20 summit came out with promises to do what they could to stimulate the global economy. Between the trillions that the U.S. is spending on economic stimulus, along with the efforts being made around the world, it really is not that surprising of an assertion.… Continue

Time Value of Data

by Kesavan, H.

We have all heard of time value of money. What could this "time value of data" mean?

All organizations these days are sitting on mountains of data and struggling to make sense of this data avalanche. In their desire to stay competitive, these organizations tend to store as much data as they can, for a 'rainy' day as they say, for they do not know which data would be useful when.

Notwithstanding this sad state of affairs in organizations,… Continue

Since the beginning of…

Believe it or not, the concept of data quality has been touted as important since the beginning of the relational database. The original concept of a relational database came from Dr. Edgar Codd, who worked for IBM in the 1960s and 70s. Dr. Codd’s ideas about relational databases, storing data in cross-referenced tables, were…

Here's a Thought - BI Nuggets from SmartData Collective

An occasional series in which a review of recent posts on SmartData Collective reveals the following nuggets:

Who’s in charge here?

A recent survey of business and IT leaders carried out by Kalido shows that over two thirds of businesses have no clear data governance program, and have no plans to implement one — and 13% are unclear as to what data governance even is. The research also reveals that nobody knows…

MECE Approach to Business Intelligence (BI) initiative

by Kesavan, H.

"MECE" stands for "Mutually Exclusive, Collectively Exhaustive". I am sure you must have guessed by now where that term comes from. If you said "Mckinsey", bingo! You can pat yourself on your back.

MECE is an approach that Mckinsey consultants religiously follow to find professional solutions to all their client problems. Given a problem statement, MECE addresses the problem by listing at the top level all issues making up that problem. Once the list… Continue

Hidden Decision Trees - A Better Approach to Scoring

Hidden Decision Trees is a statistical and data mining methodology (just like logistic regression, SVM, neural networks or decision trees) to handle problems with large amounts of data, non-linearities and strongly correlated independent variables.

The technique is easy to implement in any programming language. It is more robust than decision trees or logistic regression. Implementations typically rely heavily on large, granular hash tables.

No decision tree is… Continue

Common Sense approach to Consulting

by Kesavan,H

As consultants, we are expected to provide solutions to problems by application of (i)methodical approach to business analysis (ii)experience gained earlier from the same industry and (iii) the knowledge of industry best practices documented across the enterprise. It is a given that big Consulting companies recruit some of the best talent available around them and they also have a rich knowledge base that can be harvested for any new projects. Despite these… Continue

Closing the loop in BI

by Kesavan,H.

The significance of Business Intelligence (BI) has gained lot of currency over the last few years and lots of companies have jumped onto the BI bandwagon in the hope of finding the proverbial needle - namely, "actionable intelligence" - in the haystack of "data".

With a deluge of data confronting the companies nowadays, people at all levels of an enterprise have started realizing that implementing a BI system is more a necessity than a luxury. But… Continue

What am I doing with my blogging? A Theory Forge for Quantitative Risk Management!

Is it a vanity project? Am I writing a story with a beginning a middle and an end? In a way Yes! I really started blogging here on Analytic Bridge, Vincent Granville encouraged me, back in the day when Analytic Bridge had few members. I thought Analytic Bridge was an optimal place to blog references to banking supervision papers which had a quantitative orientation generally and I think I was correct in that. Now I have to blog corporately, I have to support the company in which I am a partner.… Continue

Beware of using ATS when applying for Jobs Online!

Today practically every company has some sort of ATS (Applicant Tracking System). With unemployment heading north and Job Candidates sending sometime 70 to 80 resumes out per week there are a couple of things you need to know.

Sending your resume using many of the largest online job boards like Monster and CareerBuilder might not help you as much as you think with finding a new job!

Today more than ever, companies are trying to grab as many resumes into their database as… Continue

Thomas Breuer Martin Jandacka

Klaus Rheinberger Martin Summer

[The authors] give a precise operational definition to three requirements the Basel Committee on Banking Supervision specifics for stress tests: Plausibility and severity of stress scenarios as well as suggestiveness of risk reducing actions. The basic idea of our approach is to define a suitable region of plausibility in terms of the risk factor distribution and search systematically for the worst portfolio loss over… Continue

Are Banks Different? Evidence from the CDS Market - Oesterreichische Nationalbank (OeNB)

Burkhard Raunig and Martin Scheicher Oesterreichische Nationalbank (OeNB)

February 16, 2009

This paper uses regression analysis to compare the market pricing of the default risk of banks to that of other firms. The authors study how CDS traders discriminate between banks and other type of firms and how their judgement changes over time, in particular, since the start of the recent financial turmoil. The authors use monthly data on the Credit Default Swaps (CDS) of 41 major banks… Continue
