Comments on IMF Working Paper on Estimating the Size of Shadow Economy in Europe



This post is a continuation of a series of the difficulties of modelling illicit financial activity and the need to understand that the results of such models are estimates not facts when we use those results.


On 13 Dec 2019 the IMF published Working Paper 19/278 Explaining the Shadow Economy in Europe: Size, Causes and Policy Options written by B. Kelmanson, K. Kirabaeva, L. Medina, B. Mircheva and J. Weiss.

Before discussing this publication, just a note that IMF WPs do not represent the IMF’s official position, but report on research in progress and are designed to elicit comment and feedback.

While the WP is “rich” in content, I’d like to highlight a few points for comment. Because as usual AA has an axe to grind.

Defining and Measuring the “Shadow Economy”  (Pages 5-6)

There are several key take-ways here.
  1. Different Definitions - There are different definitions of the “shadow economy”.  And so, it’s important to know which definition is being used in an estimate.  It’s like Transparency International’s Corruption Perception Index.  Are we measuring all corruption in a country or just a subset?
  2. Estimates Not Measurement - What is actually going on is not measurement in a formal sense.  But an attempt to estimate the size. A critical difference.  One can directly measure AA’s weight.  Or the distance from Bayt Meri to Beirut. But one can’t directly measure this or that person’s intelligence.  One has to estimate it.
  3. There is No Single Infallible Method for Such Estimations – in the authors’ words “There is no ideal or leading method to measure the shadow economy, each of them have some conceptual or practical strengths and weaknesses. The choice of the methodology can be governed by data availability, or the research objectives. Multiple methods can be employed to improve accuracy of the estimations.”
  4. Each Model has its Limitations - In discussing the model they used (MIMIC), the authors state: “The shortcomings of this method include sensitivity to changes in data and specifications, the sample used, calibration procedures, and starting values (Breusch 2005).”
Results – False Precision
  1. The tables of results are on page 25 and 26.
  2. The results appear very precise.
  3. The authors have come up with results to the tenth of one percent.  Or in non percentage terms .001.  That is some pretty fine parsing for estimates of the size of something that is unknown.
  4. Not only that but they have been able to order the sizes of the shadow economies among various countries.
  5. In the first table (page 25), France is 15.3% while in Germany is at  15.9%.  In the second table, the scores are 15.0% and 16.7% respectively.
  6. Is this precision really possible?
  7. What about the caveats about models and estimates in the previous section?
  8. Shouldn’t we expect to see less precision?
  9. Use of ranges?  Grouping of countries into similar baskets.  For example, Germany and France have roughly the same size shadow economies.
  10. AA has his axe out now. I made the argument in an earlier post on Transparency International’s CPI that when valuing the credit worthiness of an issuer rating agencies place similar firms in broad categories, AAA, AA, A etc.  They don’t parse creditworthiness of individual firms within a category. And since I have a habit of repeating myself made the same arguments in another post about modelling illicit financial flows.
  11. Similarly in valuing firms, stock analysts come up with a range for the value of stock, not a single point estimate.
  12. The point I want to make yet again is that we need to treat results from such modelling efforts as directional not locational. They are not precise but only give an indication of the real state of affairs. And when we use them, we need to keep that in mind.
Implications: Likely Underreporting of “Total” GDP

Ignoring the shadow economy means that we are likely underreporting the total or “true” GDP of a country – that is the GDP from its formal sector and that from its informal or shadow sector.  

Where the shadow economy is relatively small, this probably doesn't make much of a difference. 

But if the authors’ estimates that the shadow economy in the CIS countries is around 40% of formal GDP (page 7) are correct, then typical characterizations of CIS “dismal” economic performance based on only formal GDP are probably less true than they appear.

This does not of course “excuse” the fact that a good portion of this activity is taking place “off the books”.

BIS Releases Discussion Paper on Designing Prudential Treatment for Crypto-Assets



Yesterday the BIS Basel Committee on Banking Supervision (BCBS) released a discussion paper on “Designing a Prudential Treatment for Crypto-Assets”.

The purpose of the paper is to solicit comments about several principles that the BIS BCBS proposes to employ in designing such a framework.

It’s important to note that the BCBS does not have the legal authority to compel national jurisdictions to accept its rules and regulations.

Rather it relies on its influence as a multi-national organization to secure voluntary co-operation.

In that regard, it is like the FATF/GAFI—which develops standards for anti-money laundering and countering the financing of terrorism. Both are the primary global standard setters for their respective areas of expertise.

The BCBS’s clout derives from its membership – 45 regulators and banking supervisors from 28 jurisdictions across the globe.

Failure of a national jurisdiction to accept BIS or FATF/GAFI standards generally places it “outside” of what are generally accepted norms and places it at a disadvantage to those jurisdictions that accept the standards.

It’s also important to note that the BCBS sets standards for financial institutions and their regulators.

So this exercise doesn’t seek to directly regulate Crypto-Assets but rather banks involvement with this asset class and how national regulators would assess and control the risks that these assets pose to individual banks and national and global banking systems.

Key elements from this paper are:
  1. The BCBS assessment that Crypto-Assets do not meet the definition of currency – medium of exchange, store of value, unit of account. Hence the BCBS’s use of the term Crypto-Assets instead of Crypto-Currencies. That may seem like arguing over semantics.  But if the BCBS pronounces that Bitcoin et al are not currencies, it is likely that national regulators will adopt a similar view with consequences for their treatment of these assets.
  2. The BCBS view of risks of these assets.
  3. The proposed prudential (regulatory) treatment of banking exposures to these assets in view of the perceived risks.
This paper isn’t the final word.  Rather it’s the first step in the process.

The BCBS will publish comments it receives.  Those interested in crypto-assets will find these replies useful in furthering their understanding of this asset class.

Turning Point in the War on Christmas

AA Engages the Enemies of Christmas 
"You'll Have to Pry Christmas from my Cold Dead Hands"
AA can now report that there has been a major victory in the War on Christmas – a victory so stunning that it almost certainly marks a turning point in this long-lived bitter conflict.

We have a new experience. We have victory - a remarkable and definite victory.

Now this is not the end. It is not even the beginning of the end. But, it is, perhaps, the end of the beginning.

One remarkably achieved in non-Christian Asia.  And like another Asian battle, that of Midway, likely to prove just as significant.

Arqala Major—AA’s brother recounted to this reporter that on a flight from Bangkok to Phnom Penh on Asia’s Boutique Airline he witnessed or rather heard this glorious victory unfold first hand.

Experts in matters of foreign policy and the military arts know that this flight is under one hour.

Scarcely time it would seem for a real battle. Yet in that scant amount of time a dramatic rout occurred.

Because the flight time is one hour, there really is not time enough for typical in-flight entertainment.  So the airline showed some short comedic films of hidden camera pranks to lull the adversaries and catch them off their guard.

Then suddenly the faint sounds of “Sleigh Ride Together” followed by “Winter Wonderland”. Admittedly, not religious songs.  Yet songs about Christmas.

The first salvo in a string of songs which softened up the fortified positions of those who would take Christmas away from us. The decisive blow came with a rousing instrumental of “Joy to the World”.

Just as the plane touched down, an instrumental version of “Christmas Don’t Be Late” by Alvin and the Chipmunks completed the theological codex.

Victory! Glorious Victory!

But there is more.

AA’s brother further reported that later that day he went to a mall celebrating “Black Friday” with discounts up to 70% on selected merchandise for shoppers.  Yet another fundamental aspect of the Christmas Holiday Season – sales and discounts – in full swing.

But as one battle ends another begins.

We cannot rest until final victory.

On to theThanksgiving Front!
