This year, as in the previous years, Marc Lavoie and Gennaro Zezza will be presenting the Stock-Flow-Consistent modeling approach at the Minsky Summer Seminar at the Levy Institute.
Winter School on Agent Based and Stock Flow Consistent modelling.
Limerick, January 30th – February 7th
If you are a highly motivated student of economics at masters or Ph.D. level, or you are working with a research center or a public institution and want to spend one week studying, researching, discussing, and exchanging experiences in the nice atmosphere of an Irish University campus nurtured by international experts and fellow students from all around the world, our winter school offers you 7 working days of lectures, seminars, and labs on Stock-Flow Consistent and Agent Based approaches. For more information, see http://s120.ul.ie/drupal/winterSchool and Applied Macro-modelling – Call For Application.
The annual conference of the Research Network Macroeconomic and Macroeconomic Policies in Berlin had two sessions dedicated to stock-flow models, plus other papers using this approach in other sessions.
The program is available here
An excellent piece of analysis of Flow of Funds data at the Bank of England:
Richard Barwell and Oliver Burrows, “Growing fragilities? Balance sheets in The Great Moderation”, Financial Stability Paper No. 10 – April 2011
This article, “Flow-of-funds analysis at the ECB”, provides an excellent technical description of the European system for flow-of-fund statistics, and some good examples of how they are used at the ECB.
I would recommend it for anyone interesed in anyone doing SFC empirical modeling. It is a pity that the authors have not discovered yet the work of Godley and the book Monetary economics, which is well known at the Bank of England.

A wide variety of approaches, methodologies and topics were presented during the first workshop, allowing for interesting discussions and exchanges. Clearly, the complementarities of the Stock-Flow Consistent and Agent-Based approaches emerged, even if some were skeptical at first. The influence of finance, fiscal austerity and the construction of the euro zone are at the heart of applied work from both approaches. Furthermore, the topics and issues addressed by papers from both methodologies are similar. On the methodology side, SFC and ABM practitioners share issues regarding estimation or the role of expectations. On the first issue, the workshop has featured some presentations about methods that could be used to improve the matching between theory and data in both SFC and ABMs. An open issue there, and that could be developed in future workshop, is how far to go in the model calibration and estimation exercises. Indeed, both types of exercises impose strong restrictions on models (e.g. about the ergodicity of the dynamics) which could be limiting in terms of the ability of the model to catch salient features of the reality or that could be hard to detect into some models. Furthermore, the ABM literature has developed robustness checks and stability analysis that need to be further developed in SFC models. This highlights the interest of confronting the two approaches.
This workshop also showed us the importance of getting together and confronting our analysis and results. In particular, the workshop has highlighted the strong complementarities existing between ABM and SFC models. On one hand, SFC models have so far been developed as general aggregative models, i.e. as systems of stock-flow consistent equations describing the laws of motion of the economy at the aggregate level. On the other hand, ABMs provide explicit micro-foundations to macroeconomic relations that, in ABMs, are emergent properties of the disequilibrium interactions occurring among heterogeneous agents. However, the use of the stock-flow consistent approach in ABMs has so far been limited (few exceptions to this are represented by the models of Kinsella et al., 2012 and by Seppecher and Salle, 2012, Raberto et al. 2012). The use of the stock-flow consistent approach in ABMs could thus contribute to improve the rigor of the micro-foundations provided by these models. However, it could also help to micro-found many of the Keynesian dynamics emphasized by SFC models. This is important also because, as it was pointed out in the workshop, SFC models are particularly suitable to study the effects of imbalances at the aggregate level. However, by construction, they cannot study the factors underlying the emergence of those imbalances, such as for example the factors leading to bubble-and-burst dynamics in asset markets. Finally, we should mention the possibility of having some kind of mixed models where some sectors are agent based and others aggregated. Combining ABM and SFC allows thus to offer a wide variety of models with more or less complexity and different levels of aggregation, depending of the subject under scrutiny.

Public Debt Management in a Dynamic Stock-Flow Consistent Model: Implications for the Brazilian case
Authors: Breno Santana Lobo – José Luis Oreiro
The existence of floating-rate bonds in the composition of public debt is associated with some factors that tend to negatively affect the trajectory of the economy over time. The main objective of this article is to analyze the changes caused by a change in the public debt composition over the dynamics of a given economy. In order to do that , we built a dynamic stock-flow consistent post-keynesian model, in which the government bond market is modeled to reflect the main features of the Brazilian case. The parameters and initial conditions of the model are calibrated in order to form a baseline scenario that reflects in a satisfactory way the main stylized facts of modern economies. The simulation results indicate that the extinction of floating-rate bonds does not have negative effects on the economy in the short run. In the long run, however, uncontrolled public spending due to an increase in the debt service takes the economy to a path of instability. To stabilize the economy, government should adjust its economic policy to its debt management policy. Fiscal policy, monetary policy and income policy may be used by the government. A restrictive fiscal policy can be useful to stabilize the economy. However, it is associated with smaller growth rates. An active fiscal policy, associated with some specific objective, can reverse this result, suggesting that the fiscal policy can contribute to control inflation. Restrictive monetary policy can also be used to stabilize the economy. However, it is not the best policy to control inflation. Income policy has the best results.
After a first very fruitful workshop in Dijon (Going Further … Together: www.antoinegodin.eu/dijon) and a second venue in Limerick (Building a Common Language: www.antoinegodin.eu/limerick), which we hope to be highly stimulating, we will conclude this series of workshops in Berlin, during the FMM conference.
Indeed, two sessions (8 papers) will be dedicated to SFC modeling. We wish to remain within the areas described in the original call for papers (see attachment) and thus encourage papers addressing the following topics:
• The theory of employment and unemployment
• Possibilities and limitations of monetary and fiscal policy
• Labor market institutions, active labor market policies, and decent jobs
• Industrial policy, productivity and outsourcing
• Green jobs and limits to growth
• Working time and employment in a stagnating economy
However, papers treating other subjects related to the call for papers of the first two workshops (empirics, micro foundations, policy recommendation) will also be considered. Please note that all papers will be forwarded to the conference organizers should they decide to include SFC models in other sessions. Furthermore, more than one paper per author may be proposed, either via this call for paper or via the conference call for paper (firstname.lastname@example.org).
The deadline for paper proposals is 30 June 2013. Please send an abstract (one page) to email@example.com. Decisions will be made in early August. Registration forms for the introductory lectures and the conference will be made available online in mid-August. Accepted papers should be sent by 15 October to be posted on the conference web page.
Selected papers might be published after the conference in a special issue of the European Journal of Economics and Economic Policies: Intervention (EJEEP) dedicated to SFC modeling.

SFC Workshop, Kemmy Business School, University of Limerick, 26-27 of August 2013
After a first very fruitful workshop in Dijon, we now turn to a second workshop in Limerick.
A wide variety of approaches, methodologies and topics were presented during the first workshop, allowing for interesting discussions and exchanges. Clearly, the complementarities of the Stock-Flow Consistent and Agent-Based approaches emerged, even if some were sceptical at first. Furthermore, the topics and issues addressed by papers from both methodologies are similar. On the methodology side, SFC and ABM practitioners share issues regarding estimation or the role of expectations. The influence of finance, fiscal austerity and the construction of the euro zone are at the hart of applied work from both approaches.
This workshop also showed us the importance of getting together and confronting our analysis and results. The need to develop a common language surfaced. We will target this workshop, held at the University of Limerick, Ireland, to begin to work towards a common language for the posing of problems and the discovery of solutions to those problems.
Call for paper
We encourage papers building bridges between SFC and ABM methodologies. However any paper treating on either of the methodologies will be considered, as the goal is also to get together. The deadline for paper proposals is 30 June 2013. Please send an abstract (one page) to firstname.lastname@example.org. Decisions will be made by mid-July.
Hotel costs will be covered for all participants. Transportation costs will be covered for some participants (especially Ph.D. students), if requested when submitting a paper.
