«  Particle Monte-Carlo simulation: improvements using Hamiltonian Dynamics»

Abstract: « We present particle techniques, the principle of which could be intuitively thought of as an adaptive importance sampling, alternating with resampling in order to control the actual number of draws. It applied to the case of hidden variables and rare events simulation. Bayesian estimates of posterior distribution require filtering techniques, we shall show a method based on the Hamiltonian property of the geodesic flow on the statistical manifold to improve on exploration of a state space, It turns out to be particularly efficient in high dimensional problems. »

You are most welcome to invite the students from other axis/ Universities.

Warning: The PhD Lunch Seminar will be followed at 1pm by the seminar of the Finance and Modeling axis, with guest Matthieu Garcin, Quant Crédit at Natixis.

NORMES COMPTABLES EUROPÉENNES : L’EFRAG APRÈS LE RAPPORT MAYSTADT, NOUVELLE FEUILLE DE ROUTE

 

En janvier 2014, Philippe Maystadt était venu présenter ses propositions transmises à Michel Barnier pour que l’Europe maîtrise sa stratégie en matière de normalisation comptable dans le cadre de la convergence internationale ordonnancée par l’IASB. Il s’agissait alors de donner une nouvelle dimension à l’EFRAG et définir une gouvernance sur la base d’analyse des propositions de l’IASB et la transmission  d’avis à la Commission Européenne pour décision.

La France a toujours été très attachée aux  interrelations entre les normes comptables et leur impact économique et prudentiel sur les entreprises concernées. Au-delà du seul objectif de comparabilité qu’elles visent, on s’intéresse à la dimension « politique » que présupposent ces normes, comme c’est d’ailleurs le cas avec les USGAAP aux Etats-Unis.

Abstract

Le « minage » du Bitcoin apparaît au premier abord absurde : une colossale quantité de moyens (puces spécialisées, installations, électricité) est dépensée pour décider qui gagnera chaque 10 minutes les quelques Bitcoins créés par le protocole de Satoshi Nakamoto, et non pas pour participer à la gestion de la blockchain et à la surveillance des transactions qui ont un coût négligeable comparé à la course pour le calcul du « hash ». Pourtant une analyse plus fine montre que ces calculs apparemment absurdes se retrouvent « contenus » dans la blockchain et contribuent à la rendre infalsifiable, ce qui est essentiel pour la robustesse du protocole général. En cas de « fork » c’est d’ailleurs ce contenu en calcul qui permet de résoudre l’état incohérent du réseau dû à la présence de plusieurs blockchains valides concurrentes. Nous étudierons cette étrange situation mal théorisée aujourd’hui, nous parlerons de la notion mathématique de « contenu en calcul » (la « profondeur logique de Bennett » liée mais différente de la « complexité de Kolmogorov ») qui aide à penser proprement le problème des algorithmes de consensus, dont on ne sait pas aujourd’hui s’ils peuvent réellement éviter ce coût du minage d’une blockchain publique et ouverte comme celle du Bitcoin.

Public Authority and Finance:

What is the Relevant Scale and Scope of Deregulation and Re-Regulation?

Abstract submission by February 15, 2017

PRESENTATION

This conference seeks to contribute to the ongoing research into financial regulation, combining approaches by economists, legal experts, political scientists, geographers and historians. It aims to adopt an empirical approach from a comparative and historical perspective to characterize public authority and its relationship to the financial sector.

Learn more

Since the late 1960s, major changes have taken place in this relationship: the Chicago school of economics and public choice theory have challenged the legitimacy of government action; progress in communications and convergence of technological levels between countries and territories have undermined national regulations; jurisdictions engage in regulatory competition to attract resources; representative democratic politics is often captured by financial interests, etc.

The broad concepts of deregulation and globalization are usually viewed as the main processes that have led to the dismantling of the authority of nation-states while new regulatory entities have emerged, with the financial sector playing a leading role in these phenomena. For instance, capital controls were substantially lowered during the 1980s, while some regulatory areas have been delegated to supranational bodies such as the Basel committee on banking supervision or the International Accounting Standards Board. Since the 2008 crisis, national governments have regained some initiative in exercising public authority over finance, as with the Dodd-Frank Act in the US, or the set of normative texts adopted by the European Union during the term of EU Commissioner Barnier. Many initiatives are still being driven by international bodies such as the G20 or the Financial Stability Board, while some regulatory power is being delegated to foreign authorities under “equivalence regimes” justified by international frameworks. These complex developments suggest that national governments are no longer the only relevant decision-making level, and that regulation is not only a matter of competition. As a result, views about “regulatory competition” might be flawed because they wrongly focus too much on competition between national public authorities.

Interdisciplinary research is essential to understanding the dislocation and the reconstitution of public authority, in order to shed light on: legal and institutional changes; the behavior of actors that makes such changes possible; the scientific and electoral arguments put forward concerning regulation; the economic consequences of regulatory change and their perception by the public; and also the emergence of a new regulatory geography based on national governments, international agreements and international bodies. In place of a fragmented world of nationally-partitioned zones, a heterogeneous continuum is emerging in which the authority of public agencies acts within a global jurisdiction: for example when a French bank is fined in New York for dollar operations in Africa and Asia. The topology of such pan-national regulation needs to be made intelligible, and its political legitimacy assessed, especially in view of rising nationalist politics.

Overall, developments since the crisis thus suggest there is still the need for future changes in order to realign the interests of finance with the broader interests of national and global economies, as well as the public interest more generally.

We invite papers from different disciplines to examine three main areas, to understand better the various aspects of the relationship between public authority and finance today:

  1. Ideology, Technology and Regulatory Effectiveness
    Learn more

    This area covers the ideological justifications of deregulation (public choice, corruption and political distortions), and the technological developments permitting rules to be circumvented: well before “fintech” became fashionable, alternative exchange platforms had undermined market regulation and given rise to high frequency trading. Now, unregulated crypto-currencies evade money laundering regulations, etc. Precise timelines of the relations between these technological (or ideological) changes and their legal consequences (like the repeal of the Glass-Steagall Act) are required. More generally, it may be asked on what political-theoretical grounds public authority should act today?

  2. The Role of New Regulatory Players and the New Frontiers of Public Authority
    Learn more

    Case studies could analyze the recent history, showing for instance how the traditional public authorities handed over their regulatory powers to new independent entities, either private (such as FINRA and PCAOB) or public (as it is mainly the case in continental Europe, such as the European Supervisory Authorities), be they national or international. Forward looking contributions, for instance on the possible form and impact of the global financial registry suggested by Thomas Piketty, or indeed on the possible deregulation by the Trump administration, are appreciated. More theoretical contributions could address general questions such as the legitimacy (collective and/or individual) of such authorities. Under what principles do they operate? What kind of financial activities (especially the diverse shadow banking sector) should be optimally covered by different kinds of authorities? Will they be able to adapt to further financial innovation? How can the capture of public authorities be better dealt with?

  3. Changes in the (Territorial) Scope of Financial Regulation
    Learn more

    Do financial markets working in parallel reflect a multi-polar world or a continuum? What areas of homogeneity can be identified? What is the present situation, and what is desirable? What, for example, would be the effects of a global financial registry on tax evasion of financial wealth-related inequalities? Do we need global regulators or supervisors for financial institutions (such as banks) in order to prevent the capture or leniency of national authorities? Or is a global framework with national implementation (as initiated by the Financial Stability Board, FSB) enough to prevent systemic risk? Only the United States seems to have shown its authority over international banks by clearly fining them for misconduct. So what are the theoretical foundations for having authorities encompassing multiple jurisdictions? Does such an authority need to be the universal expression of one state or an effective public authority reflecting true multilateral commitments? Alternative constructions of finance may be examined within this framework: for instance, does Islamic finance offer a consistent international rule of law, or is it an expression of local idiosyncrasies?
