         13-14 Sept 2016  Invited Speaker at Financial Risk and Network Theory Workshop

                 Centre for Risk Studies and FNA, Judge Business School, Cambridge

          Sheri presents new work (with Inacio Manjama and Qi Zhang) on why granular global macro-net
                  models are needed :

         Unsustainable Global Macroeconomic Trends : New Granular Macro-net
                Models for Macroeconomics and Macro Prudential Policy

           The talk identifies 3 major sources of economic malaise and unsustainable trends, which, if not addressed in the medium term
              can derail OECD economies for the foreseeable future.  Firstly, the longstanding offshoring of supply chains in leading OECD
              countries has made the domestic production networks to become fragile and suffer loss of connectivity with growing holes. Sheri 
              compares this to a diseased brain with Alzheimer's that loses functionality. There is also reduced capacity of domestic systems
              to sustain wage growth in many sectors. Secondly, financialization which has increased the size of the financial sector and the
              arrogation of a very large percentage of corporate surpluses (over 60% in the US ) underscores the paucity of real investment in
              these economies and also the growing income inequality.  Using the Ghosh inverse function, we show the GDP loss from

            increasing financial sector share of gross operating profits in the US will be 6 times more in 2011 than in 1997.  Thirdly, QE

            which was ushered in as a fire fighting exercise has become a semi-permanent fixture with the close to zero or negative

            interest  rate regimes unleashing a ‘money- go- round’ series  of carry  trades and asset bubbles which exacerbate the unstable
               trends that are already endemic. We apply the network based granular macroeconomics of Acemoglu-Carvalho-Gabaix, as well

            as the Markose et. al. macro-net approach to identify the disproportionate size of economic actors/sectors such as the financial

            sector as being the major cause of  extreme GDP volatility and macro-prudential instability.

         31May- June 4  Sheri Visits IMF and Office of Financial Research (OFR), 

              USA, Washington DC             

             While there, Sheri delivered a number of talks on the need to use more data
               driven granular and interconnected models in macroeconomic and macro-

                prudential models.
               She also spoke about the financial network modelling for systemic risk
               management: Applications to cross border banking system and over the counter
               derivatives reforms.

               The talk was followed by technical discussions with IMF staff on:

bullet            Network methods for systemic risk indices for early warning
bullet            The integration of systemic risk analysis and stress testing
bullet            Carry trades and agent based models.


           For Sheri's critique on why there are serious legacy problems at institutions such
               as the IMF to move on from perspectives and models (heavy with implausible
               assumptions and poor data resolution ) that got us into deep trouble with the 2007

           22 January 2016  Bruegel, Brussels, Belgium 

             The Bank of England in Europe: Does EU membership constrain non-                  Euro central banks?

             The ECB and its response to crises in the euro area have been in the spotlight recently.
                       But, how does EU membership affect the central banks of non-Euro member states? This
                      question is especially pertinent in the UK, whose relationship with the EU is at a vital

              crossroads .  

              Bruegel welcomes Jon Cunliffe, Deputy Governor for Financial Stability at
                       the Bank of England, who will present the Bank’s report. This will be followed by a
                       discussion of the findings with Sheri Markose, University of Essex, and Matt Holmes,
                       Deutsche Bank.



               24 November 2015 Bruegel, Brussels, Belgium

                Post-Crisis Financial Stability: Vulnerabilities, Legacies, Policies

            IMF Director José Viñals will discuss the 2015 October IMF Global Financial
                     Stability Report. He will suggest that an urgent policy upgrade is vital to normalise

            monetary and financial conditions and to anchor financial stability. 

            This will be followed by a discussion with Sheri Markose from the University of Essex

             and a representative from business, chaired by Bruegel Senior Fellow Nicolas Véron

              Lectures at Leading Chinese Universities : Agent based Computational Economics, Digital
                       Economics and Digital Network Models of the Economy     


                     Considerable swathes of the economy from retail trade, financial markets, money and
                     information have gone digital.  However, Economics Departments in the UK  curtailed in their
                     capacity to innovate and embrace diversity due to the so called REF (Research Excellence
                     Framework) which restricts analysis to traditional economic models, have been slow on the
                     uptake.  The lectures I did for the Chinese Universities (and at the HMT mini-conference)
                     summarizes the vast software developments I with co-authors (mostly CCFEA PhD students) have
                    done to date on smart markets and digital network models.

                     Essex University Economics Department is the only UK Economics Department where there is
                     PG training
in  Agent based Computational Economics and data driven Digital network models
                     of the economy.

             Sheri will be a speaker at the 2015 ECMI Conference at the National Bank of Belgium on
                        the 20 October to discuss the new EC financial market infrastructure developments in the
                        context of the European Capital Markets Union.  Sheri’s contributions will focus on her
                        work on reforming the Over-the-Counter (OTC) derivatives reforms which were implicated
                        in the 2008 financial crisis.  This is a high level conference, which includes policy makers
                        such as Lord Jonathan Hill, European Commissioner for Financial Stability, Financial
                        Services and Capital Markets Union. 

                       Following the conference, she has been invited to contribute to a  closed door meeting with
                       representatives of the European Commission to discuss the European Capital Market Union
                       on the 21 October.

            Monday 6 July 2015

                     Morning (2 hours):  Introduction to Systemic Risk and Macro-prudential Modelling: Market Prices Based
                     Methods v Network Analysis of Financial Interconnections

                     This lecture covers the desirable characteristics that one needs from systemic risk indexes.  Early warning
                     signal (avoiding false negatives) is upheld to be high on this list.  Market price based systemic risk indexes
                     lack early warning and may mislead about systemic risk as volatility indexes do. Bilateral asset-liability data
                     based network models for financial systems are needed to see how procyclical liabilities exceed financial
                     buffers, leading to system wide instability. 

                     Afternoon (2 hours): Why Topology Matters in Financial Networks: Granularity, Stability and Tipping

                      Many influential models have been misleading about the stability of financial networks by considering
                     only  their connectivity and assuming homogeneity in the number and size of links of nodes. Real world
                      networks are highly heterogeneous in the number and size of links, increasing connectivity in such systems

                      can be dangerous.   I show how the Robert May characterization of stability of a network system in terms of
                       its spectral properties as a dynamical system gives us a handle in determining financial stability and
                       points. Both the index of stability of the financial network and the rank order of systemic importance and

                       vulnerability can be obtained simultaneously as part of the eigen-pair solution.  

                     Tuesday 7 July 2015

              Morning (2 hours) : New Global Granular Macro-Net Models for Macruprudential Policy

                      The challenge is to marry, at a high level of data granularity, the financial networks with the real sectors of

                       economies, along with a global/cross border dimension for both.  Ignoring cross border imbalances in macro-                       prudential policy and systemic risk modelling is a fatal error. Hence, it is important to combine cross
                       border imbalances with
within country sectoral imbalances that have emerged with the growing size of the
                       financial sector (including housing and mortgages) a la Carvalho-Gabaix-Acemeglu granular macro-economics.
                       Specific analysis of the Euro zone core-periphery crisis will be done.

              Afternoon (2 hours) :  Complexity and Computability in Economics
                      There is a fundamental non-computability at the heart of economic interactions that economists have hitherto
                       ignored. It is the basis of organized complexity that produces highly contextual innovations and structure
                       changing dynamics as in arms races.
It is produced by the interactions of highly sophisticated mentalizing
                       agents who can perceive opposition or contrarian/anti-coordinated structures. Fixed points involving
                        contrarian interactions cannot be computed.  These can become launch pads for protean behaviours that can
                       produce novel objects and surprises. Evidence for such mutual mentalizing is given from latest discoveries in
                       neuroscience on mirror neurons by Vittorio Gallesse et. al. and also from the work of Scot Kelso, who
                        identified neuro markers for anti-coordination and opposition.

                 ESRC Conference on Diversity in macroeconomics: New perspectives from
                agent-based computational, complexity and behavioural economics

                     Conference Report now available conference report

             University of Essex , UK
                     24-25 February 2014

                     This ESRC conference, cohosted with the Economics Department of the University of Essex and organized by
                     Sheri Markose
, will critically examine established thinking and bring together a range of new perspectives on
                     identifying future directions  for macroeconomics and policy. It will address developments from at least three
                     new branches of economics:  agent-based computational, complexity and behavioural economics - arising
                      from highly interdisciplinary studies of computational and digital technologies, complexity sciences and
                     neuro-physiology of the brain.


                 Topics cover behavioural macroeconomics, financial macro-nets, agent based models for systemic risk and
                    how to deal with uncertainty and complexity in policy.  Speakers include  practitioners such as Neil Erickson
                     (Fed Reserve), Sujit Kapadia (Bank of England), David Miles (Monetary Policy Committee)  and James
                     Richardson (HMT, ESRC Council), and academics, Michelle Baddeley, Doyne Farmer, Charles Goodhart, Ithzak                     Gilboa, Paul de Grauwe, Sheri Markose, Marcus Miller and KathyYuan.

                 In order to better understand herding and anti-herding that are key to boom-bust cycles, leading neuro-
  scientists Vittorio Gallese and Scot Kelso will speak on mirror neurons and their role in social cognition,
                     mimetic behaviours and also anti-coordination necessary for innovation.

Sheri Markose Interview at GES

          March 2011- 30 Dec 2011 Systemic Risk From Global Financial Derivatives IMF Project

Sheri Markose was appointed by the Department of Monetary and Capital Markets of the
            International Monetary Fund to lead research on a project on modelling systemic risk from financial
           derivatives. She visited the IMF, 6-9 December 2011 to present her results. She has characterized
 the phenomenon of too interconnected to fail (TITF) as one in which the failure of a highly
     connected large complex financial intermediary (FI) can bring down the top tier of 22 clustered
         similarly  connected FIs. She has designed a super-spreader tax based on the eigenvector centrality
     of  the LCFIs so that they internalize the cost of their systemic risk to the rest of the system. The
      highly  tiered structure of the derivatives market enables her to construct a lite superspreader tax
               escrow  fund of only $40 bn which can prevent the failure of the highly unstable $650 trillion global derivatives market.

    Sheri Markose and Amadeo Alentorn  have finally got their paper in press The Generalized Extreme Value (GEV)Distribution, Implied Tail Index and Option Pricing
Journal of Derivatives
. Spring edition, Volume 18, No 3, 2011.

              Stephen Figlewski (JOD Editor) and a referee said that the paper was very
                         'illuminating'  about the behaviour of  fat tailed (GEV Frechet ) distributions for asset returns under extreme market conditions.

Markose & Alentorn obtain a close form solution for the GEV option price. They say:
We find that the traded option price implied GEV model for the Risk Neutral Density (RND)yields results that
               strongly  challenge traditionally held views on tail behaviour of asset returns based on Gaussian distributions
              which predicate  simultaneous existence of thin tails in both directions during all market conditions. The GEV
               distribution for asset   prices  which is governed by the tail shape parameter is found to switch tail shape with
       underlying market conditions. Further, a non-zero value for the tail shape parameter results in significant
                 skewness in the probability mass of the GEV density function during extreme market conditions which implies
                    large one directional movements and truncation in the     probability mass in the other direction. During extreme
               market drawdowns, a positive value for the tail shape parameter of the GEV RND function for losses implies
                  extreme price drops with the large probability mass on the right and a finite tail in the other direction implying
              an upper bound on possible gains. To date, proposed option pricing models intended to deal with both the
            fat tail and the skew in asset returns have failed to highlight the above characteristic features of fat tailed distributions."

               All  Matlab codes for the GEV option pricing model, GEV RND implied statistics such as volatility, Extreme Economic VaR  etc.   will soon be available  at  .       .
