Economist article describing the size of the informal economy e.g. "4% GDP" in Europe

Bringing light to the grey economy

Mostly this article bemoans the loss of tax revenue and discusses how easy it will be to avoid it in the future, but in passing it hints at the importance of the informal economy -- and this does not include all the unpaid work people do (housework, child caring etc.).

Will informal value exchange develop in parallel with DIY constrution of items?

There are two movements around of interest:
  • The 'maker' movement of people customising and making their own devices, clothes etc. using the new technologies of 3D printers, computer-controlled lathes, Arduino boards etc. Here plans and expertise is often swapped freely without payment.
  • Alternative currencies and value exchange systems that pass around value without involving traditional money (bitcoin, ripplepay, baby sitting circles etc.)
It will be interesting to see if these two come together in any substantial way. Some makerspaces do have alternative currencies to lower the barriers to the involvement of cash-strapped participants, but that is localised and on a very small scale. Maybe non-traditional value-creation needs a non-traditional value exchange system - it will be interesting to see!

Blog post by David Hales on Labour Finance and Industry Group (LFIG) blog

I was asked to write a short blog post for the Labour Finance and Industry Group (LFIG) blog on P2P financial systems. The Labour Party (the main centre-left opposition political party here in the UK) is in the process of forming new policy for the next election and consults widely within academia and beyond. I was very glad to asked to write a post on P2P finance which I think could become a major countering force to large "to-big-to-fail" institutions.

Here is the post:

Supporting Peer-to-Peer Financial Services for Economic Resilience
by David Hales; 27 May 2013

The current monoculture

Financial services, particularly those provided by banks, are dominated by a small number of large players. This severely limits choice, competition and innovation. One of the most serious consequences of this, evidenced by the current crisis, is lack of resilience over the entire financial system.

How can new entrants be encouraged to provide innovation, diversity and choice to promote resilience?

Recently “peer-to-peer” (P2P) approaches to financial services have emerged that use innovative technology platforms and business models. Policy makers should proactively support these approaches since they potentially offer new levels of innovation and choice promoting the public good.

Peer-to-Peer innovation – two waves

In recent years there has been a growth of so-called “peer-to-peer” (P2P) approaches to financial functions. For example, P2P lending and more recently P2P money.

P2P lending (1)  removes the mediating role of a traditional bank by allowing savers to lend directly to borrowers. This leads to better interest rate deals for both parties although the default risk is borne by the lender. There are a number of P2P lending companies offering variants on how borrowers are matched to lenders and how risk is mitigated. P2P lending services distribute the process of borrowing and lending but rely on centralised online platforms (operated by the P2P lending companies) and on money created by traditional banks and supplied by lenders.  A more recent and radical P2P innovation is to provide money itself in a P2P way.

A P2P monetary system called Bitcoin (2)  has attracted much interest recently. Bitcoin does not rely on any centralised entity. The currency – Bitcoins – are created and tracked by each user within the system running a piece of software (called a client) on their computer. There is no organisation or company that owns or controls the system. Bitcoins can be exchanged using online exchanges or directly between users through their client software – similar to sending an e-mail. One way to think about Bitcoins is that they are like electronic cash without requiring an intermediary – such as a bank – to store or record transactions. It works by using a sophisticated computer algorithm based on cryptography and distributed computer concepts.

Put crudely, Bitcoin provides a distributed and trusted ledger or database. Every client program contains an up-to-date list of all accounts and how many coins they contain. Transactions are not allowed if they violate the data in the ledger – i.e. you cannot spend your coins more than once. But why would anyone trust this algorithm? Because it is open source meaning anyone can view the code to verify that it does what it claims.

Bitcoin does not depend on the whims of an owning corporation, a monetary policy committee or the political stability of a nation. It is a self-organised distributed software system. The innovations in Bitcoin could be as revolutionary as the invention of double entry bookkeeping and the joint stock company (3)  – because they can be freely adapted and applied within other systems. Bitcoin could become a competitor to traditional currencies but, more importantly, it has already inspired competitors and variants (4). I do not wish to promote Bitcoin per se but rather the open and innovative P2P model that allows for rapid innovation.

We might term P2P lending as a “first wave” innovation – the focus is on disruptive business models within a traditional company structure. Systems such as Bitcoin could be termed “second wave” innovations – they disrupt the very notion of a business model in the same way that open source operating systems based on Linux offer alternatives to Apple and Microsoft.

In the future new second wave systems might provide other services such as store of value, credit creation or fully distributed markets.

Supporting second wave P2P

First wave systems already have a UK trade body and productive interactions with regulators and the policy apparatus (5) .

Second wave systems are more amorphous. Anyone can create an open source system and recruit others to participate. No formal legal entities exist that are responsible for the code. Yet this is not a bug – it’s a feature. It drives high rates of experimentation and innovation.

On the other hand for new systems to gain wide use it is necessary to promote trust, interoperability and acceptance.

How can this be achieved?

One approach might be a voluntary certification process. Where certain desirable features are present, such as open source code transparency; transaction integrity; and support of interoperable standards; then various levels of certification could be awarded via a suitability composed organisation. Such an organisation should proactively support promising second wave projects providing the necessary expertise to examine the code and provide advice to developers if they wish to attain certain certification levels.

The Bitcoin community, through the recently created Bitcoin Foundation (6) , is already pursuing these goals for Bitcoin. Policy makers should proactively engage with these kinds of initiatives in order to support the development of second wave P2P approaches.

A key outcome of such a collaboration would be to provide the right regulatory environment and interoperable standards (7)  to allow for productive innovation and diversity by levelling the playing field with traditional banking – which receives huge implicit public subsidies yet provides limited resilience or choice.

Paper from Marseilles workshop participant, Guilherme da Fonseca-Statter: "The Edonomy as a Complex System"

Guilherme da Fonseca-Statter
The Economy as a Complex System
Contribution for a Marxian Inspired
ABM or AbCE Analysis

Guilherme gave a talk to the workshop on "Re-Evaluating Value" held last week in Marseilles, on The Labour Theory of Value.  This is the paper in which his ideas are explained in greater depth.

Part of the Introduction:

This paper is intended to be a very short version of an eventual future «doctoral thesis» on the
general theme of complexity sciences and to be dedicated to the specific theme of a certain
empirical law of behaviour of the capitalist system. As a consequence of the fundamental problem
indicated in the opening paragraphs no attempt has been made to actually develop or present
formal modelling specifications. The idea, at this stage, is to present the overall description of a
future model that should be developed within the next two years. In any case it is my firm belief
that a trained programmer could build a realistic model using just the specifications that are
provided here. It has been done before (with much less sophisticated tools and techniques), there
is no reason why it could not be done now.

Workshop on: "Re-evaluating Value...", Marseille June 17-18th 2013

Workshop on:
Re-evaluating Value – non-market value models for changing times
Mediterranean Institute for Advanced Research, Aix-Marseille University,
Marseille, France,, June 17-18th 2013

The Topic

Value is a major aspect of any economic theory: what it is, how it is produced, measured, stored and transferred between agents. Indeed, historically, these aspects characterise different schools of political economy.  Some approaches focus on an objective basis for value such as labour or physical resources. Others place emphasis on subjective judgments by individual agents and free exchange between them.

Recent, often ICT mediated, developments such as “commons based peer production”, “crowd funding”, “freecycling” and new virtual currencies do not fit easily into existing economic models of value.   On the other hand “complexity science” tools and approaches allow for a widening of traditional models of value.

Traditional models have focused on agents using either object or subjective notions of value and equilibrium points. Agent-based modelling allows for experimentation with new and hybrid notions of value in non-equilibrium conditions.  In these, value might be an emergent phenomena where agents construct notions of value through the interplay of subjective and objective factors supporting novel forms of exchange and cooperation.

In this workshop we aim to bring together researchers from different disciplines such as economics, philosophy, anthropology, law and computer science, who are working towards new conceptions of value, models that embody them and real world systems that depend on them.

Day 1 - Grand Challenges

The first day of this workshop is devoted to opening up the key issues to do with theories and approaches to understanding value at the present time.  It is open to all who are interested. The day will start at 9.30 and end at 4.30pm with an hour for lunch and two 30 min coffee breaks.  Talks will be 30 mins long plus 15 mins for discussion.

Day 2 – Developing Agent-Based Models to Meet the Challenges

The second day of the workshop is devoted to informal discussions about developing simulation models that start to address some of the different conceptions of value.  It is not expected that everyone will stay for day 2, or all of day 2, but is open to all who want to seriously discuss the development of relevant simulation models. The day will start at 10am and continue for the rest of the day, or until everyone is tired.

Speakers and Discussants

The following people are either invited speakers or will be leading a discussion session (in alphabetical order), followed by their talk title if available.
  • Bruno Vetel, “Who benefits from the value? Virtual currencies design for a massively multiplayer online role playing game.”

Hotels and food

Others at the workshop are staying at the hotel Lutetia ( You will need to book yourself into this, or at another hotel (e.g. via  On monday night, a dinner is planned at Les Panisses, please let Juliette ( know if you you plan to join us for this before 9th June (we think we can cover this and lunch for participants, assuming we do not get too many).


The Hotel

Hotel Lutetia, 38 Allée Gambetta, is easy to attain from the train station: go down the stairs, cross the street and walk down the street facing you (Boulevard d'Athènes). “Allée Gambetta” where the hotel is, is the second or third street on the left.

·        To go from the airport to the train station, the best solution is to take the shuttle from/to airport/gare Saint Charles (cheaper and nicer than taxis who are unpleasant thieves in their majority in Marseille) - buy a return ticket while going out of the terminal and get on the bus – in 25 minutes you can get to the train station at any time of the day.

The Meeting Venue

·        To go from the hotel to the meeting place you can walk (15-20 minutes) or take the tram for a part of the journey. The address to get in is 2 place Le Verrier and maps can be found on:

·        Walking: Walk up the Allée Gambetta to the top, turn left/right and carry more or less on in the same direction on Boulevard Longchamps. Go up to the end of the boulevard and when facing the palais (huge museum) turn left and carry on going up on a street with serious traffic, walking on the right side. carry on until the Place Le Verrier. On your right you will find a large black grid which will be open. Get in and find the building of the institute.

·        Tram: take the tram at Canebière Garibaldi and get down at Longchamps, then you will see the Palais Longchamps and turn around the palais on the left, as for the walking instructions.
      From the station, it is also possible to take the subway, and cross the Jardin du Palais Longchamps (a very nice park) and a maps can be found at:

In you get lost: beware : locals do not know the place so well – you have to refer to “Maison des Astronomes”, which is its old name, but is known to something like 10% of the population.
