title: Credit Risk and Collateral Demand in a Retail Payment System
Creators: name: Saiz, Héctor Pérez
name: Xerri, Gabriel
Publisher: name: Bank of Canada
Year: 2016

description: The recent financial crisis has led to the development of new regulations to control risk in designated payment systems, and the implementation of new credit risk management standards is one of the key issues. In this paper, we study various credit risk management schemes for the Canadian retail payment system (ACSS) that are designed to cover the exposure of a defaulting member. We consider schemes that use a collateral pool calculated using a rolling time window. Our simulations show that the size of the window has a very significant effect on the average level of collateral and its variability day to day, creating an interesting trade-off. Collateral levels and variability may be important for ACSS participants because they could affect the opportunity costs of pledging collateral, and also the costs of managing it over time. Our results contribute to understanding the practical implementation of risk management schemes in the current and future generations of payment systems in Canada.
description: La récente crise financière a donné lieu à l’élaboration de nouvelles règles visant à contrôler les risques dans les systèmes de paiement désignés, et la mise en oeuvre de nouvelles normes de gestion du risque de crédit revêt à cet égard une grande importance. Nous étudions dans le présent document plusieurs méthodes de gestion du risque de crédit pour le système canadien de paiement de détail, à savoir le Système automatisé de compensation et de règlement (SACR), qui sont conçues pour couvrir l’exposition au risque de crédit pouvant résulter de la défaillance d’un participant. Nous examinons des méthodes faisant appel à un fonds commun de sûretés calculé sur une période mobile dans le temps. Nos simulations montrent que la longueur de la période a une incidence très significative sur le niveau moyen de sûretés et sur sa variabilité d’une journée à l’autre, produisant un arbitrage intéressant entre ces deux éléments. Les niveaux de sûretés et leur variabilité peuvent s’avérer importants pour les participants au SACR, car ils pourraient influer sur les coûts d’opportunité de la mise en gage des sûretés, ainsi que sur les coûts de gestion de ces sûretés au fil du temps. Nos résultats permettent de mieux comprendre l’application pratique de méthodes de gestion du risque au sein des générations actuelles et futures de systèmes de paiement au Canada.
title: The Role of Central Banks in Promoting Financial Stability: An International Perspective
Creators: name: Cunningham, Rose

Publisher: name: Bank of Canada
Year: 2016

description: The 2007–09 global financial crisis has led policy-makers around the world, including central banks, to refocus their efforts to promote financial stability. As part of this process, central banks became quite active in supporting financial stability in a variety of ways, such as publicly sharing their assessments of financial system vulnerabilities and risks and helping to strengthen regulation, supervision and macroprudential measures. However, the use of monetary policy instruments for managing financial stability risks is more widely debated because central banks may face a trade-off between attaining their inflation targets in a timely manner and exacerbating financial stability risks. Recent research suggests that central banks that tend to have stronger financial stability mandates and less influence over regulatory and macroprudential tools are more likely to use monetary policy to address financial stability risks.
description: La crise financière mondiale de 2007-2009 a amené les décideurs publics du monde entier, y compris les banques centrales, à réorienter les efforts déployés pour favoriser la stabilité financière. Dans le cadre de ce processus, les banques centrales se sont appliquées à soutenir la stabilité financière de diverses façons, notamment en communiquant publiquement leurs évaluations des vulnérabilités et des risques du système financier et en contribuant à renforcer la réglementation, la surveillance et les mesures macroprudentielles. Le recours à des mesures de politique monétaire dans le but de gérer les risques menaçant la stabilité du système financier est toutefois plus largement débattu, les banques centrales devant éventuellement trouver un arbitrage entre l’atteinte en temps voulu de leurs cibles en matière d’inflation et l’aggravation des risques liés à la stabilité financière. D’après des études récentes, les banques centrales qui tendent à accorder une place prépondérante à la stabilité financière au sein de leur mandat et à influer dans une moindre mesure sur les outils réglementaires et macroprudentiels sont plus susceptibles de se tourner vers les mesures de politique monétaire pour contrer les risques liés à la stabilité financière.
Turbulent drag reduction by anisotropic permeable substrates $-$ analysis and direct numerical simulations

description: We explore the ability of anisotropic permeable substrates to reduce turbulent skin-friction, studying the influence that these substrates have on the overlying turbulence. For this, we perform DNSs of channel flows bounded by permeable substrates. The results confirm theoretical predictions, and the resulting drag curves are similar to those of riblets. For small permeabilities, the drag reduction is proportional to the difference between the streamwise and spanwise permeabilities. This linear regime breaks down for a critical value of the wall-normal permeability, beyond which the performance begins to degrade. We observe that the degradation is associated with the appearance of spanwise-coherent structures, attributed to a Kelvin-Helmholtz-like instability of the mean flow. This feature is common to a variety of obstructed flows, and linear stability analysis can be used to predict it. For large permeabilities, these structures become prevalent in the flow, outweighing the drag-reducing effect of slip and eventually leading to an increase of drag. For the substrate configurations considered, the largest drag reduction observed is $\approx 20-25\%$ at a friction Reynolds number $δ^+ = 180$.

We perform a systematic expansion around the mean-field solution, obtaining the universal crossover curves and their leading corrections. In particular we show that, in three dimensions, the leading correction scales as $R^{-3}, R$ being the range of the interactions. We compare our results with the existing numerical ones obtained by Monte Carlo simulations and present a critical discussion of other approaches.

description: The structure of a nonuniform Lennard-Jones (LJ) liquid near a hard wall is approximated by that of a reference fluid with repulsive intermolecular forces in a self-consistently determined external mean field incorporating the effects of attractive forces. We calculate the reference fluid structure by first determining the response to the slowly varying part of the field alone, followed by the response to the harshly repulsive part. Both steps can be carried out very accurately, as confirmed by MC simulations, and good agreement with the structure of the full LJ fluid is found.

description: The peak effect (PE) has been observed in a twinned crystal of YBa$_2$Cu$_3$O$_{7-δ}$ for H$\parallel$c in the low field range, close to the zero field superconducting transition temperature (T$_c$(0)) . A sharp depinning transition succeeds the peak temperature T$_p$ of the PE. The PE phenomenon broadens and its internal structure smoothens out as the field is increased or decreased beyond the interval between 250 Oe and 1000 Oe. Moreover, the PE could not be observed above 10 kOe and below 20 Oe. The locus of the T$_p$(H) values shows a reentrant characteristic with a nose like feature located at T$_p$(H)/T$_c$(0)$\approx$0.99 and H$\approx$100 Oe (where the FLL constant a$_0$$\approx$penetration depth $λ$).

description: Recent DFT (density functional theory) simulations showed that metals have a hitherto overlooked symmetry termed "hidden scale invariance" [Hummel {\em et al.}, Phys. Rev. B {\bf{92}}, 174116 (2015)]. According to isomorph theory, this scaling property implies the existence of lines in the thermodynamic phase diagram, so-called isomorphs, along which structure and dynamics are invariant to a good approximation when given in properly reduced units. This means that the phase diagram becomes effectively one-dimensional with regard to several physical properties. This paper investigates consequences and implications of the isomorph theory in six metallic crystals; Au, Ni, Cu, Pd, Ag and Pt. The data are obtained from molecular dynamics simulations employing many body 'effective medium theory' (EMT) to model the atomic interactions realistically. We test the predictions from isomorph theory for structure and dynamics by means of the radial distribution and the velocity autocorrelation functions, as well as the rather dramatic prediction of instantaneous equilibration after a jump between two isomorphic points. Many properties of crystals tend to be dominated by defects and many of the properties associated with these defects are expected to be isomorph invariant as well. This is investigated in this paper for the case of vacancy diffusion. We find the predicted invariance of structure and also of dynamics, though less rigorous. We show results on the variation of the density scaling exponent $γ$, which can be related to the Grüneisen-parameter, for all six metals. We consider large density changes up to a factor of two, corresponding to very high pressures. Unlike systems modelled using the Lennard-Jones potential where the density scaling-exponent $γ$ is almost constant, it varies substantially when using the EMT potential and is also strongly material dependent.

description: We study the small-world networks recently introduced by Watts and Strogatz [Nature {\bf 393}, 440 (1998)], using analytical as well as numerical tools. We characterize the geometrical properties resulting from the coexistence of a local structure and random long-range connections, and we examine their evolution with size and disorder strength. We show that any finite value of the disorder is able to trigger a ``small-world'' behaviour as soon as the initial lattice is big enough, and study the crossover between a regular lattice and a ``small-world'' one. These results are corroborated by the investigation of an Ising model defined on the network, showing for every finite disorder fraction a crossover from a high-temperature region dominated by the underlying one-dimensional structure to a mean-field like low-temperature region. In particular there exists a finite-temperature ferromagnetic phase transition as soon as the disorder strength is finite.

description: Information technology (IT) is an increasingly integral part of everyday business and personal life reflecting the ongoing and accelerating digital transformation of the economy. In this paper, we present information gathered from a survey with export-oriented firms in the Canadian IT service industry and consultations with industry associations aimed at shedding light on this small but highly dynamic sector. Our main findings from this survey are: (i) IT service firms experience strong sales growth and tend to be very positive about their outlook, driven by the solid exports that comprise the majority of their sales; (ii) in this context, firms overwhelmingly view the weaker Canadian dollar as favourable, boosting their margins on foreign sales; (iii) because of the knowledge-intensive nature of the industry, firms report investing in human capital more than in physical capital. This often comes with strong employment and R&D investment intentions, although firms in some regions face difficulties in recruiting qualified staff. The survey results provide initial insight in the context of our broader agenda to better understand the implications of digitalization for the Canadian economy.
description: Les technologies de l’information (TI) font de plus en plus partie intégrante de nos activités professionnelles et personnelles, sous l’effet de la transformation numérique permanente et accélérée de l’économie. Dans cette étude, nous présentons l’information recueillie lors d’une enquête menée auprès d’entreprises à vocation exportatrice du secteur canadien des services TI ainsi que de consultations auprès d’associations industrielles dans le but de mieux cerner ce secteur, petit mais très dynamique. L’enquête nous a permis de faire les principaux constats suivants : 1) les entreprises de services TI connaissent une forte croissance des ventes et sont généralement très optimistes quant à leurs perspectives, portées par les exportations vigoureuses qui représentent la plus grande partie de leurs ventes; 2) dans ce contexte, une immense majorité des entreprises considèrent que le niveau plus bas du dollar canadien est avantageux, puisqu’il leur permet de dégager des marges bénéficiaires plus importantes sur les exportations; 3) compte tenu de la nature du secteur, qui dépend fortement du savoir, les entreprises déclarent investir davantage dans le capital humain que dans le capital physique. Cet état de fait se traduit souvent par une ferme intention d’embaucher du personnel et d’investir dans la recherche-développement. Dans certaines régions, les entreprises ont toutefois de la difficulté à recruter du personnel qualifié. Cette enquête apporte de premiers enseignements dans le cadre du programme que nous nous sommes fixé en vue de mieux comprendre les implications de la numérisation pour l’économie canadienne.

description: The survey for DUST In Nearby Galaxies with Spitzer (DUSTiNGS) has identified hundreds of candidate dust-producing Asymptotic Giant Branch (AGB) stars in several nearby metal-poor galaxies. We have obtained multi-epoch follow-up observations for these candidates with the Spitzer Space Telescope and measured their infrared (IR) lightcurves. This has allowed us to confirm their AGB nature and investigate pulsation behavior at very low metallicity. We have obtained high-confidence pulsation periods for 88 sources in seven galaxies. We have confirmed DUSTiNGS variable star candidates with a 20% success rate, and determined the pulsation properties of 19 sources already identified as Thermally-Pulsing AGB (TP-AGB) stars. We find that the AGB pulsation properties are similar in all galaxies surveyed here, with no discernible difference between the DUSTiNGS galaxies (down to 1.4% solar metallicity; [Fe/H]=-1.85) and the far more metal-rich Magellanic Clouds (up to 50% solar metallicity; [Fe/H]=-0.38). These results strengthen the link between dust production and pulsation in AGB stars and establish the IR Period-Luminosity (P - L) relation as a reliable tool (+/- 4%) for determining distances to galaxies, regardless of metallicity.

title: Implementing Cross-Border Interbank Lending in BoC-GEM-FIN

Year: 2016

description: BIS interbank lending data show that the Great Recession generated large and persistent changes in the international interbank lending positions of various countries. The main objective of this study is to understand the role of changes in international interbank credit flows in transmitting shocks across borders. To accomplish this task, we needed a global structural model with an international interbank market. Our search for a suitable structural model revealed that the Bank of Canada version of the global economy model (BoC-GEM-FIN) comes closest to our needs. BoC-GEM-FIN includes region-specific interbank markets, as well as some international borrowing and lending, but abstracts from the international interbank lending. This paper describes the modifications we made in order to introduce the international interbank market into BoC-GEM-FIN. The modified model is calibrated to match the changes in international interbank lending positions and the decline in the business lending of US banks that took place after the fourth quarter of 2008. Our simulations show that the international interbank market amplifies spillover effects of demand shocks but does not systematically alter the effects of supply shocks, including those for commodities.
description: Les données de la Banque des Règlements Internationaux relatives au financement interbancaire montrent que la Grande Récession a changé considérablement et durablement les positions de financement interbancaire internationales de plusieurs pays. La présente étude a pour principal objectif de comprendre l’incidence des changements de flux de crédit interbancaires internationaux sur la transmission transfrontière des chocs. Ainsi, il nous fallait un modèle structurel mondial intégrant un marché interbancaire international. Nous avons trouvé que la version du modèle économique mondial de la Banque du Canada – soit le modèle BoC-GEMFIN – répondait le mieux à nos besoins. Ce modèle tient compte de marchés interbancaires propres à une région ainsi que de certaines activités internationales d’emprunt et de prêt, mais fait abstraction du financement interbancaire international. Dans les lignes qui suivent, nous décrivons les modifications que nous avons apportées au modèle BoC-GEM-FIN pour y intégrer le marché interbancaire international. Nous avons calibré le modèle modifié pour faire correspondre les changements de positions de financement interbancaire internationales à la diminution du nombre de prêts consentis aux entreprises par les banques américaines qui est survenue après le quatrième trimestre de 2008. D’après nos simulations, le marché interbancaire international amplifie les effets de débordement des chocs de demande, mais ne modifie pas systématiquement les effets des chocs d’offre ni ceux des chocs liés aux produits de base.

description: The present study aimed to assess the role of miR-1275 in cardiac ischemia reperfusion injury. H9 human embryonic stem cell (hESC)-derived cardiomyocytes stimulated by oxygen-glucose deprivation/reoxygenation (OGD/R) were used to simulate myocardial injury in vitro. miR-1275 expression levels in cells were measured by RT-qPCR. The release of lactate dehydrogenase (LDH) and creatine kinase (CK) was examined through LDH and CK ELISA kits. Cell apoptosis was detected through flow cytometry. A Fura-2 Calcium Flux Assay Kit and a Fluo-4 assay kit were used to determine the Ca2+ concentration. Expression levels of proteins were tested by Western blotting. The binding effect of miR-1275 and neuromedin U type 1 receptor (NMUR1) was detected by dual-luciferase activity assay. The results showed that miR-1275 was upregulated in OGD/R-stimulated cardiomyocytes. Inhibition of miR-1275 suppressed the increased activity of LDH and CK, cell apoptosis, reactive oxygen species (ROS) production, intracellular Ca2+ concentration and sarcoplasmic reticulum (SR) Ca2+ leak induced by OGD/R treatment in cardiomyocytes. miR-1275 directly targets 3ʹUTR of NMUR1 and negatively regulates NMUR1 expression. Silence of NMUR1 abolished the protecting effect of the miR-1275 antagomir on myocardial OGD/R injury. Our study indicated that the miR-1275 antagomir protects cardiomyocytes from OGD/R injury through the promotion of NMUR1.

description: An approximate relativistic two-component Hamiltonian for use in molecular electronic structure calculations is derived in the form of a sum of fixed atom-centered kinetic and spin-orbit operators added to the non-relativistic Hamiltonian. Starting from the well-known zeroth-order regular approximation, further steps are taken to get rid of its nonlinearity in the potential, ending up with a simple formulation with easily computable integrals that can seamlessly work with any traditional electronic structure method. Molecular tests show a good accuracy of this approximation.

Creators: name: Gao, Jeffrey

Publisher: name: Bank of Canada
Year: 2018

description: This paper finds that Government of Canada benchmark bonds tend to be more illiquid over the subsequent month when there is a large increase in government debt supply. The result is both statistically and economically significant, stronger for the long-term than the short-term sector, and is robust when other macro factors are controlled for. The result is consistent with the interpretation that risk-averse dealers tend to provide less liquidity to the market when facing increased duration risks brought by large debt issuance. The fact that the newly issued bonds are much less liquid may also contribute to the impact of debt supply on market liquidity.
description: Dans cette étude, les auteurs constatent que les obligations de référence du gouvernement du Canada sont généralement moins liquides dans le mois qui suit une forte hausse des émissions de titres de dette publique. Le résultat, qui est statistiquement et économiquement significatif, et plus probant à long terme qu’à court terme, se confirme lorsqu’on neutralise l’effet d’autres facteurs macroéconomiques. Ce résultat cadre avec la thèse selon laquelle des courtiers réfractaires au risque sont moins enclins à fournir des liquidités au marché lorsqu’ils encourent des risques de durée accrus en raison d’une importante émission de titres de créance. Le caractère beaucoup moins liquide des nouvelles obligations pourrait aussi contribuer à l’incidence des émissions des titres de dette sur la liquidité du marché.

Furthermore, we present triangle-like inequality for the convex-roof extended negativity for any states of rank 2, which gives a positive answer to a conjecture raised in [Phys. Rev. A 96, 062308 (2017)]. Detailed examples are given to illustrate the relations characterized by the triangle-like inequalities.

description: It is well known that the Fractional Quantum Hall Effect (FQHE) may be effectively represented by a Chern-Simons theory. In order to incorporate QH Skyrmions, we couple this theory to the topological spin current, and include the Hopf term. The cancellation of anomalies for chiral edge states, and the proviso that Skyrmions may be created and destroyed at the edge, fixes the coefficients of these new terms. Consequently, the charge and the spin of the Skyrmion are uniquely determined. For those two quantities we find the values $eνN_{Sky}$ and $νN_{Sky}/2$, respectively, where $e$ is electron charge, $ν$ is the filling fraction and $N_{Sky}$ is the Skyrmion winding number. We also add terms to the action so that the classical spin fluctuations in the bulk satisfy the standard equations of a ferromagnet, with spin waves that propagate with the classical drift velocity of the electron.

Faraday rotation in the jet of M87 inside the Bondi radius: indication of winds from hot accretion flows confining the relativistic jet

description: We study Faraday rotation in the jet of M87 inside the Bondi radius using eight Very Long Baseline Array data sets, one at 8 GHz, four at 5 GHz, and three at 2 GHz. We obtain Faraday rotation measures (RMs) measured across the bandwidth of each data set. We find that the magnitude of RM systematically decreases with increasing distance from the black hole from 5,000 to 200,000 Schwarzschild radii. The data, showing predominantly negative RM sign without significant difference of the RMs on the northern and southern jet edges, suggest that the spatial extent of the Faraday screen is much larger than the jet. We apply models of hot accretion flows, thought to be prevalent in active galactic nuclei having relatively low luminosity such as M87, and find that the decrease of RM is described well by a gas density profile $ρ\propto r^{-1}$. This behavior matches the theoretically expected signature of substantial winds, nonrelativistic un-collimated gas outflows from hot accretion flows, which is consistent with the results of various numerical simulations. The pressure profile inferred from the density profile is flat enough to collimate the jet, which can result in gradual acceleration of the jet in a magneto-hydrodynamical process. This picture is in good agreement with the observed gradual collimation and acceleration of the M87 jet inside the Bondi radius. The dominance of negative RMs suggests that jet and wind axis are misaligned such that the jet emission exposes only one side of the toroidal magnetic fields permeating the winds.

title: Incentive Compatibility on the Blockchain

Publisher: name: Bank of Canada

description: A blockchain is a digital ledger that keeps track of a record of ownership without the need for a designated party to update and enforce changes to the record. The updating of the ledger is done directly by the users of the blockchain and is traditionally governed by a proof-of-work (PoW) protocol. We formalize this protocol as a Cournot game where users compete to update the blockchain for a reward. Cheating occurs in the form of “double spending” when users try to tamper with ownership records in order to defraud their counterparties. Ruling out incentives to cheat can be summarized in the form of a “no double-spending constraint.” These constraints put restrictions on the design of a blockchain and, thus, play a role akin to incentive compatibility constraints in classic mechanism design.
description: Une chaîne de blocs est un grand registre numérique qui suit l’évolution des opérations faites par les auteurs de transactions sans devoir faire appel à un tiers chargé de mettre à jour et à exécution les changements consignés. La mise à jour du registre est faite directement par les utilisateurs de la chaîne de blocs et est habituellement régie par un protocole, la preuve de travail. Nous formalisons ce protocole comme un jeu de Cournot où les utilisateurs s’affrontent pour mettre à jour la chaîne en échange d’une récompense. Il y a tricherie – sous la forme d’une « double dépense » – lorsque les utilisateurs tentent de falsifier les transactions consignées afin d’escroquer leurs contreparties. Il est possible d’écarter ces incitations à tricher en empêchant l’inscription en double des dépenses. Cette entrave soumet à des restrictions la conception d’une chaîne de blocs et, par conséquent, joue un rôle analogue à celui des contraintes de compatibilité incitative auxquelles est assujettie la conception des mécanismes classiques.

description: The accurate measurement of security metrics is a critical research problem because an improper or inaccurate measurement process can ruin the usefulness of the metrics, no matter how well they are defined. This is a highly challenging problem particularly when the ground truth is unknown or noisy. In contrast to the well perceived importance of defining security metrics, the measurement of security metrics has been little understood in the literature. In this paper, we measure five malware detection metrics in the {\em absence} of ground truth, which is a realistic setting that imposes many technical challenges. The ultimate goal is to develop principled, automated methods for measuring these metrics at the maximum accuracy possible. The problem naturally calls for investigations into statistical estimators by casting the measurement problem as a {\em statistical estimation} problem. We propose statistical estimators for these five malware detection metrics. By investigating the statistical properties of these estimators, we are able to characterize when the estimators are accurate, and what adjustments can be made to improve them under what circumstances. We use synthetic data with known ground truth to validate these statistical estimators. Then, we employ these estimators to measure five metrics with respect to a large dataset collected from VirusTotal. We believe our study touches upon a vital problem that has not been paid due attention and will inspire many future investigations.

description: Soliton microcombs offer the prospect of advanced optical metrology and timing systems in compact form factors. In these applications, pumping of microcombs directly from a semiconductor laser without amplification or triggering components is desirable for reduced power operation and to simplify system design. At the same time, low repetition rate microcombs are required in many comb applications for interface to detectors and electronics, but their increased mode volume makes them challenging to pump at low power. Here, 10 GHz repetition rate soliton microcombs are directly pumped by low-power (< 20 mW) diode lasers. High-Q silica microresonators are used for this low power operation and are packaged into fiber-connectorized modules that feature temperature control for improved long-term frequency stability.
