description: In leptogenesis scenario, the decays of heavy Majorana neutrinos generate lepton family asymmetries, $Y_e, Y_μ$ and $Y_τ$. They are sensitive to CP violating phases in seesaw models. The time evolution of the lepton family asymmetries are derived by solving Boltzmann equations. By taking a minimal seesaw model, we show how each family asymmetry varies with a CP violating phase. For instance, we find the case that the lepton asymmetry is dominated by $Y_μ$ or $Y_τ$ depending on the choice of the CP violating phase. We also find the case that the signs of lepton family asymmetries $Y_μ$ and $Y_τ$ are opposite each other. Their absolute values can be larger than the total lepton asymmetry and the baryon asymmetry may result from the cancellation of the lepton family asymmetries.

description: We report a comprehensive study of the maximization of the spin Hall ratio (θSH) in Pt thin films by the insertion of sub-monolayer layers of Ti to decrease carrier lifetime while minimizing the concurrent reduction in the spin Hall conductivity. We establish that the intrinsic spin Hall conductivity of Pt, while robust against the strain and the moderate interruption of crystal order caused by these insertions, begins to decrease rapidly at high resistivity level because of the shortening carrier lifetime. The unavoidable trade-off between the intrinsic spin Hall conductivity and carrier lifetime sets a practical upper bound of θSH >=0.8 for heterogeneous materials where the crystalline Pt component is the source of the spin Hall effect and the resistivity is increased by shortening carrier lifetime. This work also establishes a very promising spin-Hall metal of [Pt 0.75 nm/Ti 0.2 nm]7/Pt 0.75 nm for energy-efficient, high-endurance spin-orbit torque technologies (e.g., memories, oscillators, and logic) due to its combination of a giant θSH of 0.8, or equivalently a dampinglike spin torque efficiency per unit current density of 0.35, with a relatively low resistivity (90 uOhm cm) and high suitability for practical technology integration.

Alternative Approaches for the Numerical Simulation of Glass Structural Beams Reinforced with GFRP Laminates

Publisher: name: Challenging Glass Conference Proceedings
Year: 2018

description: This paper discusses alternative numerical approaches to the analysis of the structural behaviour of glass beams reinforced with GFRP laminates adhesively bonded, which were calibrated and validated from four-point bending tests available in the literature. For this purpose, smeared crack and damaged plasticity models were used to simulate the non-linear behaviour of glass, available in FEMIX and ABAQUS finite element softwares. The interaction between the materials in the composite beams, using polyurethane or epoxy adhesives, was defined thought different strategies. In all cases it was possible to simulate well the non-linear behaviour of glass-GFRP composite beams. However, while the FEMIX (smeared crack model) results showed greater resemblance to the experimental ones, ABAQUS models, showed to be able to capture in greater detail the effects of cracking in theses structural responses.

title: Evaluating Forecasts from Factor Models for Canadian GDP Growth and Core Inflation

name: Demers, Frédérick
Publisher: name: Bank of Canada
Year: 2007

description: This paper evaluates the performance of static and dynamic factor models for forecasting Canadian real output growth and core inflation on a quarterly basis. We extract the common component from a large number of macroeconomic indicators, and use the estimates to compute out-of-sample forecasts under a recursive and a rolling scheme with different window sizes. Forecasts from factor models are compared with those from AR(p) models as well as IS- and Phillips-curve models. We find that factor models can improve the forecast accuracy relative to standard benchmark models, for horizons of up to 8 quarters. Forecasts from our proposed factor models are also less prone to committing large errors, in particular when the horizon increases. We further show that the choice of the sampling-scheme has a large influence on the overall forecast accuracy, with smallest rolling-window samples generating superior results to larger samples, implying that using "limited-memory" estimators contribute to improve the quality of the forecasts.
description: Les auteurs évaluent la capacité de modèles factoriels statiques et dynamiques à prévoir, sur une base trimestrielle, la croissance du PIB réel du Canada et l'inflation mesurée par l'indice de référence. Une fois le facteur commun extrait d'un vaste ensemble d'indicateurs macro-économiques, ils utilisent les modèles estimés pour produire des prévisions hors échantillon au moyen de deux méthodes; l'une est de type récursif, et l'autre fait appel à une fenêtre glissante de longueur variable. Les prévisions issues des modèles factoriels sont comparées à celles tirées d'un modèle autorégressif d'ordre p, d'un modèle fondé sur une courbe IS et d'un modèle formalisant une courbe de Phillips. Les auteurs constatent qu'aux horizons inférieurs à neuf trimestres, les modèles factoriels donnent de meilleures prévisions que les modèles de prévision habituels. Les modèles factoriels proposés sont également moins susceptibles de générer de larges erreurs, en particulier quand l'horizon s'allonge. Les auteurs montrent en outre que le choix du schéma d'échantillonnage influe grandement sur la qualité générale des prévisions, les fenêtres glissantes de petite taille donnant de meilleurs résultats que les gros échantillons. L'emploi d'estimateurs à « mémoire limitée » contribuerait par conséquent à améliorer la qualité des prévisions.

description: Putative global minima have been located for clusters interacting with an aluminium glue potential for N<190. Virtually all the clusters have polytetrahedral structures, which for larger sizes involve an ordered array of disclinations that are similar to those in the Z, H and sigma Frank-Kasper phases. Comparisons of sequences of larger clusters suggest that the majority of the global minima will adopt the bulk face-centred-cubic structure beyond N=500.

description: Weight-balanced trees are a popular form of self-balancing binary search trees. Their popularity is due to desirable guarantees, for example regarding the required work to balance annotated trees. While usual weight-balanced trees perform their balancing operations in a bottom-up fashion after a modification to the tree is completed, there exists a top-down variant which performs these balancing operations during descend. This variant has so far received only little attention. We provide an in-depth analysis and engineering of these top-down weight-balanced trees, demonstrating their superior performance. We also gaining insights into how the balancing parameters necessary for a weight-balanced tree should be chosen - with the surprising observation that it is often beneficial to choose parameters which are not feasible in the sense of the correctness proofs for the rebalancing algorithm.

description: Surface modification of hollow mesoporous silica nanoparticles (HMSNs) with unique advantages are highly promising for drug delivery and have emerged for effective cancer treatment. In this study, functionalized nanoparticles for targeting and dual-responsive release of loaded doxorubicin hydrochloride (DOX·HCL) and indocyanine green (ICG) (labeled as ID@HCH). In addition, chitosan (CS) was conjugated onto the HMSNs as capping agents and then dialdehyde hyaluronic acid (HDA) was modified to endow the ability to target the CD44 receptor. The characterizations demonstrated that nanocarriers have been successfully constructed with excellent drug loading capacity (DL) and drug entrapment efficiency (EE). The in vitro DOX control release displayed pH/enzyme-response properties owing to the pH-dependent swelling effect of chitosan and the HDA degraded by hyaluronidases (HAase). Moreover, the results of in vitro cell experiments proved that the ID@HCH could inhibit the cancer cells viability via accurately targeting HepG2 cells and chemotherapy combined with photodynamic therapy. This study demonstrated that ID@HCH is a new promising dual-responsive drug delivery system for chemotherapy and photodynamic therapy.

Improved depth resolution and depth-of-field in temporal integral imaging systems through non-uniform and curved time-lens array

description: Observing and studying the evolution of rare non-repetitive natural phenomena such as optical rogue waves or dynamic chemical processes in living cells is a crucial necessity for developing science and technologies relating to them. One indispensable technique for investigating these fast evolutions is temporal imaging systems. However, just as conventional spatial imaging systems are incapable of capturing depth information of a three-dimensional scene, typical temporal imaging systems also lack this ability to retrieve depth information; different dispersions in a complex pulse. Therefore, enabling temporal imaging systems to provide these information with great detail would add a new facet to the analysis of ultrafast pulses. In this paper, after discussing how spatial three-dimensional integral imaging could be generalized to the time domain, two distinct methods have been proposed in order to compensate for its shortcomings such as relatively low depth resolution and limited depth-of-field. The first method utilizes a curved time-lens array instead of a flat one, which leads to an improved viewing zone and depth resolution, simultaneously. The second one which widens the depth-of-field is based on the non-uniformity of focal lengths of time-lenses in the time-lens array. It has been shown that compared with conventional setup for temporal integral imaging, depth resolution, i.e. dispersion resolvability, and depth-of-field, i.e. the range of resolvable dispersions, have been improved by a factor of 2.5 and 1.87, respectively.

description: Using high resolution N-body simulations we address the problem of emptiness of giant 20 Mpc/h diameter voids found in the distribution of bright galaxies. Are the voids filled by dwarf galaxies? Do cosmological models predict too many small dark matter haloes inside the voids? Can the problems of cosmological models on small scales be addressed by studying the abundance of dwarf galaxies inside voids? We find that voids in the distribution of 10^12 Msun/h haloes (expected galactic magnitudes ~ M_*) are almost the same as the voids in 10^11 Msun/h haloes. Yet, much smaller haloes with masses 10^9 Msun/h and circular velocities v_circ about 20 km/s readily fill the voids: there should be almost 1000 of these haloes in a 20 Mpc/h void. A typical void of diameter 20 Mpc/h contains about 50 haloes with v_circ > 50 km/s. The haloes are arranged in a pattern, which looks like a miniature Universe: it has the same structural elements as the large-scale structure of the galactic distribution of the Universe. There are filaments and voids; larger haloes are at the intersections of filaments. The only difference is that all masses are four orders of magnitude smaller. There is severe (anti)bias in the distribution of haloes, which depends on halo mass and on the distance from the centre of the void. Large haloes are more antibiased and have a tendency to form close to void boundaries. The mass function of haloes in voids is different from the ``normal'' mass function. It is much steeper for high masses resulting in very few M33-type galaxies (v_circ about 100 km/s). We present an analytical approximation for the mass function of haloes in voids.

description: Stars spend most of their lifetimes on the `main sequence' (MS) in the Hertzsprung--Russell diagram. The obvious double MSs seen in the equivalent color--magnitude diagrams characteristic of Milky Way open clusters pose a fundamental challenge to our traditional understanding of star clusters as `single stellar populations.' The clear MS bifurcation of early-type stars with masses greater than $\sim1.6 M_\odot$ is thought to result from a range in the stellar rotation rates. However, direct evidence connecting double MSs to stellar rotation properties has yet to emerge. Here, we show through analysis of the projected stellar rotational velocities ($v\sin i$, where $i$ represents the star's inclination angle) that the well-separated double MS in the young, $\sim200Myr$-old Milky Way open cluster NGC 2287 is tightly correlated with a dichotomous distribution of stellar rotation rates. We discuss whether our observations may reflect the effects of tidal locking affecting a fraction of the cluster's member stars in stellar binary systems. We show that the slow rotators could potentially be initially rapidly rotating stars that have been slowed down by tidal locking by a low mass-ratio companion in a cluster containing a large fraction of short-period, low-mass-ratio binaries. This demonstrates that stellar rotation drives the split MSs in young, $\lessapprox 300$Myr-old star clusters. However, special conditions, e.g., as regards the mass-ratio distribution, might be required for this scenario to hold.

title: Best Instruments for Market Discipline in Banking
Creators: name: Caldwell, Greg
Publisher: name: Bank of Canada
Year: 2007

description: The author develops a dynamic model of banking competition to determine which capital instrument is most effective in disciplining banks' risk choice. Comparisons are conducted between equity, subordinated debentures (SD), and uninsured deposits (UD) as funding sources. The model, adapted from Repullo (2004), analyzes the effectiveness of regulatory capital when banks incorporate charter value and competition for depositors into their risk-taking decision. The paper's main finding is that although all three instruments can induce market discipline on banks, equity weakly dominates SD and UD (with SD weakly dominating UD).
description: L'auteur construit un modèle dynamique de concurrence bancaire pour déterminer quelle source de capitaux constitue l'instrument de discipline le plus efficace pour limiter la prise de risques par les banques. Les sources de financement qu'il compare sont les capitaux propres, les titres de dette de rang inférieur et les dépôts non assurés. À partir d'une version adaptée du modèle de Repullo (2004), l'auteur évalue l'efficacité de la structure du capital réglementaire dans un cadre où les banques décident du niveau de risque assumé en tenant compte de la valeur de licence et de la concurrence dont les déposants sont l'objet. Sa principale conclusion est la suivante : bien que les trois sources de financement considérées puissent toutes être un vecteur de la discipline de marché, ce sont les capitaux propres qui dominent généralement, devant les titres de dette de rang inférieur, lesquels dépassent légèrement en efficacité les dépôts non assurés.

description: The effects of planar hole concentration, p, on the resistivity, r(T), of sintered Y1-xCaxBa2(Cu1-yZny)3O7-d samples were investigated over a wide range of Ca, Zn, and oxygen contents. Zn was used to suppress superconductivity and this enabled us to extract the characteristic pseudogap temperature, T*(p), from r(T,p) data below Tco(p) [ = Tc (y = 0)]. We have also located the characteristic temperature, Tscf, marking the onset of significant superconducting fluctuations above Tc, from the analysis of r(T,H,p) and r(T,p) data. This enabled us to identify T*(p) near the optimum doping level where the values of T*(p) and Tscf(p) are very close and hard to distinguish. We again found that T*(p) depends only on the hole concentration p, and not on the level of disorder associated with Zn or Ca substitutions. We conclude that (i) T*(p) (and therefore, the pseudogap) persists below Tco(p) on the overdoped side and does not merge with the Tco(p) line and (ii) T*(p), and thus the pseudogap energy, extrapolates to zero at the doping p = 0.19 +/- 0.01.

description: The paper examines three equity-based structural models to study the nonlinear relationship between equity and credit default swap (CDS) prices. These models differ in the specification of the default barrier. With cross-firm CDS premia and equity information, we are able to estimate and compare the three models. We find that the stochastic barrier model performs better than the constant and uncertain barrier models in terms of both in-sample fit and out-of-sample forecasting of CDS premia. In addition, we demonstrate a linkage between the default barrier, jump intensity, and barrier volatility estimated from our models and firm-specific variables related to default risk, such as credit ratings, equity volatility, and leverage ratios.

Ils constatent que le modèle à seuil stochastique présente une meilleure adéquation statistique et permet de mieux prévoir les primes de swaps hors échantillon que les modèles à seuil constant et à seuil incertain. Les auteurs mettent aussi en évidence l'existence d'un lien entre, d'une part, le seuil de défaillance, l'intensité du saut et la volatilité du seuil estimés à l'aide de leurs modèles et, d'autre part, des variables indicatrices du risque de défaillance propre à l'entreprise telles que la cote de crédit de celle-ci, la volatilité du prix de ses actions et ses ratios de levier.

title: Credit, Asset Prices, and Financial Stress in Canada
Creators: name: Misina, Miroslav

Publisher: name: Bank of Canada
Year: 2008

description: Historical narratives typically associate financial crises with credit expansions and asset price misalignments. The question is whether some combination of measures of credit and asset prices can be used to predict these events. Borio and Lowe (2002) answer this question in the affirmative for a sample of 34 countries, but the question is surprisingly difficult to answer for individual developed countries that have faced very few, if any, financial crises in the past. To circumvent this problem, we focus on financial stress and ask whether credit and asset price movements can help predict it. To measure financial stress, we use the Financial Stress Index (FSI) developed by Illing and Liu (2006). Other innovations include the estimation and forecasting using both linear and endogenous threshold models, and a wide range of asset prices (stock and housing prices, for example). The exercise is performed for Canada, but the methodology is suitable for any country that fits the above description.
description: Dans les analyses historiques, on associe généralement les crises financières aux périodes d'expansion du crédit et aux déséquilibres de prix sur le marché des actifs. Par conséquent, un groupe de variables réunissant à la fois des mesures du crédit et du prix des actifs pourrait-il servir à prévoir les crises? Borio et Lowe (2002) répondent à cette question par l'affirmative sur la base d'un échantillon de 34 pays. La réponse est loin d'être claire, toutefois, dans le cas isolé d'un pays développé qui a peu ou pas connu de crises financières dans le passé. Les auteurs contourn ent la difficulté en mettant plutôt l'accent sur le concept de tensions financières, mesurées au moyen de l'indice mis au point par Illing et Liu (2006), et examinent si les mouvements du crédit et du prix des actifs peuvent aider à prédire l'apparition de telles tensions. Entre autres innovations, ils procèdent à l'estimation de modèles linéaires et de modèles à seuils endogènes faisant intervenir un large éventail de prix d'actifs (comme ceux des actions et des maisons), de même qu'à l'élaboration de prévisions à l'aide de ces modèles. Ils étudient plus précisément le cas du Canada, mais leur méthodologie se prête à l'analyse de la situation de tout pays développé n'ayant jamais traversé de crise financière.

description: Artificial intelligence algorithms largely build on multi-layered neural networks. Coping with their increasing complexity and memory requirements calls for a paradigmatic change in the way these powerful algorithms are run. Quantum computing promises to solve certain tasks much more efficiently than any classical computing machine, and actual quantum processors are now becoming available through cloud access to perform experiments and testing also outside of research labs. Here we show in practice an experimental realization of an artificial feed-forward neural network implemented on a state-of-art superconducting quantum processor using up to 7 active qubits. The network is made of quantum artificial neurons, which individually display a potential advantage in storage capacity with respect to their classical counterpart, and it is able to carry out an elementary classification task which would be impossible to achieve with a single node. We demonstrate that this network can be equivalently operated either via classical control or in a completely coherent fashion, thus opening the way to hybrid as well as fully quantum solutions for artificial intelligence to be run on near-term intermediate-scale quantum hardware.

description: We study single-electron quantum dots on helium surface created by electrodes submerged into the helium. The intradot potential is electrostatically controlled. We find the electron energy spectrum and identify relaxation mechanisms. Strong in-plane confinement significantly slows down electron relaxation. Energy relaxation is due primarily to coupling to phonons in helium. Dephasing is determined by thermally excited ripplons and by noise from underlying electrodes. The decay rate can be further suppressed by a magnetic field normal to the helium surface. Slow relaxation in combination with control over the energy spectrum make localized electrons appealing as potential qubits of a quantum computer.

We also estimated the cluster metallicity which turned out to be over-solar ([Fe/H]=+0.14 +/-0.06). Our Li analysis evidenced that (i) late F-type stars (Teff > 6000 K) undergo a very small amount of Li depletion during the early phases on the ZAMS; (ii) G-type stars (6000 > Teff > 5500 K) instead do deplete lithium soon after arrival on the ZAMS. Whereas this result is not new, we show that the time scale for Li depletion in these stars is almost constant between 100 and 600 Myr; (iii) we confirm that the spread observed in early K-type stars in younger clusters has converged by 220 Myr. No constraints can be put on later-type stars. (iv) Finally, we investigate the effect of metallicity on Li depletion by comparing NGC 6475 with the similar age cluster M 34, but we show that the issue remains open, given the uncertain metallicity of the latter cluster. By using the combined NGC 6475 + M 34 sample together with the Hyades and the Pleiades, we compare quantitatively Li evolution from the ZAMS to 600 Myr with theoretical predictions of standard models.

description: The Odin satellite has been used to detect emission and absorption in the 557-GHz H2O line in the Galactic Centre towards the Sgr A* Circumnuclear Disk (CND), and the Sgr A +20 km/s and +50 km/s molecular clouds. Strong broad H2O emission lines have been detected in all three objects. Narrow H2O absorption lines are present at all three positions and originate along the lines of sight in the 3-kpc Spiral Arm, the -30 km/s Spiral Arm and the Local Sgr Spiral Arm. Broad H2O absorption lines near -130 km/s are also observed, originating in the Expanding Molecular Ring. A new molecular feature (the ``High Positive Velocity Gas'' - HPVG) has been identified in the positive velocity range of ~ +120 to +220 km/s, seen definitely in absorption against the stronger dust continuum emission from the +20 km/s and +50 km/s clouds and possibly in emission towards the position of Sgr A* CND. The 548-GHz H2_18O isotope line towards the CND is not detected at the 0.02 K (rms) level.

description: We present a detailed analysis of the projected stellar rotational velocities of the well-separated double main sequence (MS) in the young, $\sim200$Myr-old Milky Way open cluster NGC 2287 and suggest that stellar rotation may drive the split MSs in NGC 2287. We find that the observed distribution of projected stellar rotation velocities could result from a dichotomous distribution of stellar rotation rates. We discuss whether our observations may reflect the effects of tidal locking affecting a fraction of the cluster's member stars in stellar binary systems. The slow rotators are likely stars that initially rotated rapidly but subsequently slowed down through tidal locking induced by low-mass-ratio binary systems. However, the cluster may have a much larger population of short-period binaries than is usually seen in the literature, with relatively low secondary masses.

Extrinsic CPT Violation in Neutrino Oscillations

description: In this talk, we investigate extrinsic CPT violation in neutrino oscillations in matter with three flavors. Note that extrinsic CPT violation is different from intrinsic CPT violation. Extrinsic CPT violation is one way of quantifying matter effects, whereas intrinsic CPT violation would mean that the CPT invariance theorem is not valid. We present analytical formulas for the extrinsic CPT probability differences and discuss their implications for long-baseline experiments and neutrino factory setups.

description: 12 original articles concerning the Paleolithic development of woven-fiber technology, illustrated with 250+ photographs and pictures. This eBook is 300+ pages long. More than 100 years ago Gustave Chauvet wrote that he believed basketry and simple weaving were present in the Upper Paleolithic sites he had studied. Yet it took almost that long to convince experts that this was the case. The discovery of irrefutable evidence in the form of impressions of weaving in clay provided the proof. Now it is also clear that basket-weaving and textile-weaving were not incompatible with the hunter-gatherer Paleolithic lifestyle and did not require the sedentary settled Neolithic way of life as had been assumed. This opens up the idea that basket-weaving or woven-fiber technology as I have called it, could have begun even in the Lower Paleolithic, millions of years ago. In these 7 articles I outline how basketry could have begun perhaps two million years ago and then how it could have developed until the rise of the great civilizations of Sumer and Egypt which depended on this technology. I include ideas about how to find indirect evidence of basket-weaving in the Paleolithic era.

Dynamical geometry for multiscale dissipative particle dynamics
Creators: name: De Fabritiis, G.
name: Coveney, P. V.
Publisher: name: arXiv
Year: 2003
Subjects: subject: Soft Condensed Matter (cond-mat.soft)
subject: FOS: Physical sciences

description: In this paper, we review the computational aspects of a multiscale dissipative particle dynamics model for complex fluid simulations based on the feature-rich geometry of the Voronoi tessellation. The geometrical features of the model are critical since the mesh is directly connected to the physics by the interpretation of the Voronoi volumes of the tessellation as coarse-grained fluid clusters. The Voronoi tessellation is maintained dynamically in time to model the fluid in the Lagrangian frame of reference, including imposition of periodic boundary conditions. Several algorithms to construct and maintain the periodic Voronoi tessellations are reviewed in two and three spatial dimensions and their parallel performance discussed. The insertion of polymers and colloidal particles in the fluctuating hydrodynamic solvent is described using surface boundaries.

Chirality Induced Spin Selectivity -- The Role of Electron Correlations

description: Chirality induced spin selectivity, discovered about two decades ago in helical molecules, is a non-equilibrium effect that emerges from the interplay between geometrical helicity and spin-orbit interactions. Several model Hamiltonians building on this interplay have been proposed and while these can yield spin-polarized transport properties that agrees with experimental observations, they simultaneously depend on unrealistic values of the spin-orbit interaction parameters. It is likely, however, that a common deficit originates from the fact that all these models are uncorrelated, or, single-electron theories. Therefore, chirality induced spin selectivity is, here, addressed using a many-body approach, which allows for non-equilibrium conditions and a systematic treatment of the correlated state. The intrinsic molecular spin-polarization increases by two orders of magnitudes, or more, compared to the corresponding result in the uncorrelated model. In addition, the electronic structure responds to varying external magnetic conditions which, therefore, enables comparisons of the currents provided for different spin-polarizations in one of the (or both) leads between which the molecule is mounted. Using experimentally feasible parameters and room temperature, the obtained normalized difference between such currents may be as large as 5 - 10 % for short molecular chains, clearly suggesting the vital importance of including electron correlations when searching for explanations of the phenomenon.

Publisher: name: Bank of Canada
Year: 2008

description: This paper develops a model of settlement system to study the endogenous structure of settlement networks, and the welfare consequences of clearing agent failure. The equilibrium degree of tiering is endogenously determined by the cost structure and the information structure. The degree of tiering is decreasing in the fixed cost of operating the second-tier network and the availability of public credit history. Furthermore, the welfare effects of clearing agent failure can be decomposed into operational inefficiency and the loss of private information.
description: Les auteurs élaborent un modèle en vue d'étudier la structure endogène des systèmes de règlement et l'incidence de la défaillance d'un agent de compensation sur le bien-être. La mesure dans laquelle les débiteurs utilisent les services d'un agent de compensation à l'équilibre pour régler leurs paiements, c'est-à-dire le degré de participation indirecte au système, est déterminée de façon endogène par la structure de coûts et la structure informationnelle. Le degré de participation indirecte varie en raison inverse du coût fixe d'exploitation du deuxième niveau du système et de la disponibilité publique des antécédents de crédit. En outre, les coûts qu'entraîne la défaillance d'un agent de compensation sur le plan du bien-être peuvent être décomposés en deux éléments : l'inefficience opérationnelle et la perte d'information privée.
