title: Anticipated Technology Shocks: A Re‐Evaluation Using Cointegrated Technologies
Creators: name: Wagner, Joel
Publisher: name: Bank of Canada
Year: 2017

description: Two approaches have been taken in the literature to evaluate the relative importance of news shocks as a source of business cycle volatility. The first is an empirical approach that performs a structural vector autoregression to assess the relative importance of news shocks, while the second is a structural-model-based approach. The first approach suggests that anticipated technology shocks are an important source of business cycle volatility; the second finds anticipated technology shocks are incapable of generating any business cycle volatility. This paper challenges the latter conclusion by presenting a structural news shock model adapted to reproduce the cointegrating relationship between total factor productivity and the relative price of investment. With cointegrated neutral and investment-specific technology, anticipated shocks to the common stochastic trend explain approximately 22%, 32%, 34% and 20% of the variance of output, investment, hours and consumption in the United States, respectively, reconciling the discrepancy between theory and data.
description: Dans la littérature, deux approches méthodologiques ont servi à évaluer l’importance relative des chocs induits par de nouvelles informations sur le futur comme source de volatilité du cycle économique. La première est une approche empirique qui fait appel à une spécification en termes de vecteur autorégressif structurel afin d’évaluer l’importance relative de pareils chocs, tandis que la seconde se fonde sur un modèle structurel d’équilibre général. Les résultats de la première approche portent à croire que les chocs technologiques attendus constituent une source importante de volatilité du cycle économique, alors que selon la deuxième, les chocs technologiques attendus ne sont pas susceptibles de provoquer une quelconque volatilité du cycle économique. La présente étude remet en question cette dernière conclusion en exposant un modèle structurel d’équilibre général comprenant des chocs induits par de nouvelles informations, adapté de façon à reproduire la relation de cointégration entre la productivité totale des facteurs et le prix relatif de l’investissement. Si l’on tient compte de la cointégration des technologies neutres et des technologies spécifiques à l’investissement, les chocs attendus en déviation par rapport à la tendance stochastique commune expliquent respectivement environ 22, 32, 34 et 20 % de la variance de la production, de l’investissement, des heures et de la consommation aux États-Unis, ce qui concilie les prédictions de la théorie avec les données.
A Historical Look at the Pittsburgh Crawfords and the Impact of Black Baseball on American Society

Publisher: name: Carnegie Mellon University

Subjects: History

description: The history and impact of Black Baseball in Pittsburgh is by no means something to be forgotten. The accomplishments in the game of its "Forgotten Heroes" alone, deserves to be recognized. Known as one of the greatest baseball clubs in the Negro leagues, the Pittsburgh Crawfords , began as a team made up of youth from the Hill District but later acquired names like Harold "Hooks" Tinker, and Hall of Famers, Josh Gibson, Satchel Paige, "Cool" Papa Bell, Judy Johnson, and Oscar Charleston. These men, through their efforts on the sandlots of Pittsburgh, paved the way for your Jackie Robinsons and Larry Dobys, who were able to break to color barriers of baseball in America. Not only did the integration of major league baseball bring about the downfall of Black baseball, but it ignited a flame for social reform in America that dominoed into the Civil Rights Movement. For years, historians have debated over the origins of integration in our society. Now, with scholarly works like Rob Ruck's Sandlot Seasons; Sport in Black Pittsburgh, Jules Tygiel's Baseball's Great Experiment; Jackie Robinson and His Legacy, and the documentary, Kings on the Hill: Baseball's Forgotten Heroes, there exist new hypotheses to engage. Finally, these gifts create a window in which we can look back and remember the rich history of Black baseball, its players, and its impact on American society.
A QCD Relation Between Hyperfine Splittings in Isospin doublets - A Light Quark Symmetry?

description: Recent data on the $D^*$ masses confirm the QCD prediction based on the \REF{\ICHJL}{Isaac Cohen and Harry J. Lipkin, \plb{84}{323}{1979}} very general assumption $\({\ICHJL}\)$ that the spin-dependence of the quark couplings to photons and gluons have the same structure and differ only in the value of the coupling constants, This prediction with no free parameters and using the $Ξ$ and $Ξ^*$ masses as input follows from noting that the charmed antiquark $\bar c$ and the strange diquark (ss) have exactly the same couplings to both the photon (Q=-2/3) and to the gluon (both are color antitriplets). New predictions are obtained with this approach. Corrections to the naive model are investigated and shown to be small.

title: Small‐Sample Tests for Stock Return Predictability with Possibly Non‐Stationary Regressors and GARCH‐Type Effects
Creators: name: Gungor, Sermin
name: Luger, Richard
Publisher: name: Bank of Canada
Year: 2017

description: We develop a simulation-based procedure to test for stock return predictability with multiple regressors. The process governing the regressors is left completely free and the test procedure remains valid in small samples even in the presence of non-normalities and GARCH-type effects in the stock returns. The usefulness of the new procedure is demonstrated both in a simulation study and by examining the ability of a group of financial variables to predict excess stock returns. We find robust evidence of predictability during the period 1948–2014, driven entirely by the term spread. This empirical evidence, however, is much weaker over subsamples.
description: Nous développons une méthode de simulation pour tester la prévisibilité du rendement des actions à l’aide de multiples variables de régression. Le processus déterminant les variables de régression n’est aucunement restreint et la méthode de simulation reste valide à distance finie même en présence de distributions autres que la loi normale et d’effets GARCH sur le rendement des actions. L’utilité de la nouvelle méthode est démontrée à la fois dans une étude de simulation et par l’examen de la capacité d’un ensemble de variables financières à prévoir le rendement excédentaire des actions. Nous observons, pour la période 1948-2014, des signes probants de prévisibilité qui s’expliquent entièrement par l’écart de taux. Toutefois, ces résultats empiriques sont beaucoup plus faibles dans le cas des sous-échantillons.

description: The Intermediate Palomar Transient Factory reported the discovery of an unusual type II-P supernova iPTF14hls. Instead of a ~100-day plateau as observed for ordinary type II-P supernovae, the light curve of iPTF14hls has at least five distinct peaks, followed by a steep decline at ~1000 days since discovery. Until 500 days since discovery, the effective temperature of iPTF14hls is roughly constant at 5000-6000K . In this paper we propose that iPTF14hls is likely powered by intermittent fallback accretion. It is found that the light curve of iPTF14hls can be well fit by the usual t^{-5/3} accretion law until ~1000 days post discovery when the light curve transitions to a steep decline. To account for this steep decline, we suggest a power-law density profile for the late accreted material, rather than the constant profile as appropriated for the t^{-5/3} accretion law. Detailed modeling indicates that the total fallback mass is ~0.2M_{sun}, with an ejecta mass M_{ej}~21M_{sun}. We find the third peak of the light curve cannot be well fit by the fallback model, indicating that there could be some extra rapid energy injection. We suggest that this extra energy injection may be a result of a magnetic outburst if the central object is a neutron star. These results indicate that the progenitor of iPTF14hls could be a massive red supergiant.

Shakespeare’s Tragic Heroines

description: Shakespeare's attitudes towards and portrayals of women have long been discussed and analyzed in many contexts, and often it seems as though sweeping generalizations are made about how he felt towards women. Based on such plays as Macbeth, Hamlet, The Taming of the Shrew, and some characters in A Midsummer Night's Dream, one might be able to conclude that Shakespeare generally did not view women as moral equals to men, and only that he viewed them as weak, manipulative, deceptive, submissive, or downright cruel. Also, in recent years, the women's movement has badmouthed his plays, claiming that even if the women he portrays are good and virtuous, they are always weak and under the control of men (such as Hamlet's Ophelia). However, statements like that become dangerous when his plays are looked at in a broader scope and when one is reminded of the time period that he wrote in. In fact, some plays actually (though somewhat subtly) end up having women as the most heroic persons in the play. And although these women do not rebel against wrongdoings in a militant and warlike fashion (as perhaps their male counterparts would), they successfully maintain their beliefs, convictions, and strengths in a quieter, but no less effectual, way.

description: Cannibals are dark matter particles with a scattering process that allows three particles to annihilate to two. This exothermic process keeps the gas of the remaining particles warm long after they become non-relativistic. A cannibalizing dark sector which is decoupled from the Standard Model naturally arises from a pure-glue confining hidden sector. It has an effective field theory description with a single massive interacting real scalar field, the lightest glueball. Since warm dark matter strongly suppresses growth of structure cannibals cannot be all of the dark matter. Thus we propose a scenario where most dark matter is non-interacting and cold but about 1 percent is cannibalistic. We review the cannibals' unusual scaling of the temperature and energy and number densities with redshift and generalize the equations for the growth of matter density perturbations to the case of cannibals. We solve the equations numerically to predict the scaling of the Hubble parameter and the characteristic shape of the linear matter power spectrum as a function of model parameters. Our results may have implications for the $σ_8$ and $H_0$ problems.

Year: 2017

description: Previously reported effects of institutional quality and political risks on foreign direct investment (FDI) are mixed and, therefore, difficult to interpret. We present empirical evidence suggesting a relatively clear, statistically robust, and intuitive characterization. Institutional factors that affect the likelihood of an abrupt and total loss of foreigners’ capital (i.e., return of capital) dominate those that affect rates of return conditional on a strictly positive terminal investment value (i.e., return on capital). A one-standarddeviation reduction in expropriation risk is associated with a 72 per cent increase in FDI, which is substantially larger than the effects of any other dimensions of institutional quality simultaneously controlled for in our empirical models of FDI inflows. This evidence is consistent with the predictions of a standard theory of FDI under imperfect contract enforcement. We show in the context of a simple model with endogenous expropriation that, when there is a binding threat of expropriation, foreign investors can become unresponsive to differences in other dimensions of institutions and political risk, and may even reduce optimal investment as these institutions improve.
description: Les effets signalés antérieurement qu’exercent la qualité des institutions et les risques politiques sur l’investissement direct étranger (IDE) sont contrastés et, par conséquent, difficiles à interpréter. Nous présentons des données empiriques qui font ressortir une caractérisation intuitive statistiquement solide. Les facteurs institutionnels ayant une incidence sur la probabilité d’une perte soudaine et totale du capital détenu par des étrangers (remboursement de capital) l’emportent sur ceux touchant les taux de rendement subordonnés à une valeur nue finale strictement positive (rendement du capital investi). Une réduction de un écart-type du risque d’expropriation est associée à une augmentation de 72 % de l’IDE, une hausse nettement supérieure à celles engendrées par n’importe quels autres aspects de la qualité des institutions pris en compte simultanément dans nos modèles empiriques d’entrées d’IDE. Ce résultat cadre avec les prédictions d’une théorie classique de l’IDE où l’exécution des contrats est imparfaite. Dans un modèle simple intégrant un facteur d’expropriation endogène, nous démontrons que, en cas de menace d’expropriation à caractère exécutoire, les investisseurs étrangers peuvent devenir indifférents aux divergences entre les autres aspects des institutions et du risque politique, et qu’ils pourraient même réduire l’investissement optimal à mesure que ces institutions s’améliorent.
Majorana oscillations modulated by Fano interference and dregree of non-locality in a topological superconducting nanowire-quantum dot system

description: We explore theoretically the influence of Fano interference in the so-called Majorana oscillations in a T-shaped hybrid setup formed by a quantum dot (QD) placed between conducting leads and side-coupled to a topological superconducting nanowire (TSNW) hosting zero-energy Majorana bound states (MBSs) at the ends. Differential conductance as a function of the external magnetic field reveals oscillatory behavior. Both the shape and amplitude of the oscillations depend on the bias-voltage, degree of MBSs non-locality and Fano parameter of the system determining the regime of interference. When the latter is such that direct lead-lead path dominates over lead-QD-lead path and the bias is tuned in resonance with QD zero-energy, pronounced fractional Fano-like resonances are observed around zero-bias for highly non-local geometries. Further, the conductance profiles as a function of both bias-voltage and QD energy level display "bowtie" and "diamond" shapes, in qualitative agreement with both previous theoretical and experimental works. These findings ensure that our proposal can be used to estimate the degree of MBS non-locality, thus allowing to investigate their topological properties.

description: We work in a general framework where the state of a physical system is defined by its behaviour under measurement and the global state is constrained by no-signalling conditions. We show that the marginals of symmetric states in such theories can be approximated by convex combinations of independent and identical conditional probability distributions, generalizing the classical finite de Finetti theorem of Diaconis and Freedman. Our results apply to correlations obtained from quantum states even when there is no bound on the local dimension, so that known quantum de Finetti theorems cannot be used.

description: In 1936, Albert Einstein wrote a brief article where he suggested the possibility that a massive object acted as a lens, amplifying the brightness of a star. As time went by, this phenomenon, known as gravitational lensing, has become a powerful research tool in astrophysics. The simplest and symmetrical expression of a gravitational lens is known as Einstein ring. This model has recently allowed the measurement of the mass of a star, the white dwarf Stein 2051 B. The purpose of this work is to show an accessible and uptodate introduction to the effect of gravitational lensing, focused on the Einstein ring and the measurement of the mass of Stein 2051 B. The intended audience of this article are non-graduate students of physics and similar fields of study, and requires only basic knowledge of classical physics, modern physics, algebra and trigonometry.

description: The discrete choice to adopt a financial innovation affects a household’s exposure to inflation and transactions costs. We model this adoption decision as being subject to an unobserved cost. Estimating the cost requires a dynamic structural model, to which we apply a conditional choice simulation estimator. A novel feature of our method is that preference parameters are estimated separately, from the Euler equations of a shopping-time model, to aid statistical efficiency. We apply this method to study ATM card adoption in the Bank of Italy’s Survey of Household Income and Wealth. There, the implicit adoption cost is too large to be consistent with standard models of rational choice, even when sorted by age, cohort, education or region.
description: Le choix discret d’adopter une innovation financière influe sur l’exposition d’un ménage à l’inflation et aux coûts de transaction. Nous modélisons cette décision d’adoption en considérant un coût non observé. L’estimation du coût nécessite un modèle structurel dynamique, auquel nous appliquons un estimateur de simulation de choix conditionnel. Notre méthode est nouvelle en ce qu’elle permet d’estimer séparément les paramètres de préférences, à partir des équations d’Euler d’un modèle portant sur le temps passé à faire les magasins. Notre démarche vise à améliorer l’efficience statistique. Nous appliquons cette méthode pour étudier l’adoption d’une carte bancaire en nous appuyant sur l’enquête sur le revenu et la richesse des ménages (Survey of Household Income and Wealth) menée par la Banque d’Italie. D’après les données d’enquête, le coût implicite d’adoption est trop élevé pour être compatible avec les résultats des modèles standard de choix rationnel, et ce, même lorsqu’un tri est opéré selon l’âge, la cohorte, le niveau d’instruction ou la région.

description: We study constrained-efficient bank capital regulation in a model with market-imposed equity requirements. Banks hold equity buffers to insure against sudden loss of access to funding. However, in the model, banks choose to only partially self-insure because equity is privately costly. As a result, equity requirements are occasionally binding. Constrained-efficient regulation requires banks to build up additional equity buffers and compensates them for the cost of equity with a permanent increase in lending margins. When buffers are depleted, regulation relaxes the market-imposed equity requirements by raising bank future prospects through temporarily elevated lending margins.
description: Nous étudions la réglementation sur les fonds propres des banques assortie d’une contrainte d’efficience dans un modèle intégrant des exigences de fonds propres imposées par le marché. Les banques détiennent des volants de fonds propres pour se protéger contre une perte soudaine d’accès au financement. Toutefois, dans le modèle, les banques décident de se protéger en partie seulement, car la formation de capital bancaire s’avère coûteuse pour elles. Par conséquent, les exigences de fonds propres sont parfois contraignantes. La réglementation assortie d’une contrainte d’efficience oblige les banques à constituer des volants de fonds propres supplémentaires et à en contrebalancer le coût par une augmentation permanente des marges d’intermédiation. Lorsque les volants sont épuisés, la réglementation assouplit les exigences de fonds propres imposées par le marché en améliorant les perspectives des banques par la hausse temporaire des marges d’intermédiation.

description: We study the possible scaling limits of percolation interfaces in two dimensions on the triangular lattice. When one lets the percolation parameter p(N) vary with the size N of the box that one is considering, three possibilities arise in the large-scale limit. It is known that when p(N) does not converge to 1/2 fast enough, then the scaling limits are degenerate, whereas if p(N) - 1 / 2 goes to zero quickly, the scaling limits are SLE(6) as when p=1/2. We study some properties of the (non-void) intermediate regime where the large scale behavior is neither SLE(6) nor degenerate. We prove that in this case, the law of any scaling limit is singular with respect to that of SLE(6), even if it is still supported on the set of curves with Hausdorff dimension equal to 7/4.

description: Many loss functions in representation learning are invariant under a continuous symmetry transformation. For example, the loss function of word embeddings (Mikolov et al., 2013) remains unchanged if we simultaneously rotate all word and context embedding vectors. We show that representation learning models for time series possess an approximate continuous symmetry that leads to slow convergence of gradient descent. We propose a new optimization algorithm that speeds up convergence using ideas from gauge theory in physics. Our algorithm leads to orders of magnitude faster convergence and to more interpretable representations, as we show for dynamic extensions of matrix factorization and word embedding models. We further present an example application of our proposed algorithm that translates modern words into their historic equivalents.

The type of ``gap equation'' which can systematically lead to extra negative contributions to the so--called $ρ$--parameter is emphasized. Furthermore general model independent features are discussed and it is shown how electro--weak precision measurements can be sensitive to the fermion content and/or dynamical features of a given theory.

These theories are realized in terms of free scalar fields starting from the simple $b-c$ systems and scalar fields on algebraic curves. The Knizhnik-Zamolodchikov equations for the conformal blocks can be explicitly solved. Besides of the fact that one obtains in this way an entire class of theories in which the operators obey a nonstandard statistics, these systems are interesting in exploring the connection between statistics and curved space-times, at least in the two dimensional case.

description: Hard optimization problems are often approached by finding approximate solutions. Here, we highlight the concept of proportional sampling and discuss how it can be used to improve the performance of stochastic algorithms for optimization. We introduce an NP-Hard problem called Max-Haf and show that Gaussian boson sampling (GBS) can be used to enhance any stochastic algorithm for this problem. These results are applied by enhancing the random search, simulated annealing, and greedy algorithms. With numerical simulations, we confirm that all algorithms are improved when employing GBS, and that GBS-enhanced random search performs the best despite being the one with the simplest underlying classical routine.

description: In 2007, the M-type binary asteroid 22 Kalliope reached one of its annual equinoxes. As a consequence, the orbit plane of its small moon, Linus, was aligned closely to the Sun's line of sight, giving rise to a mutual eclipse season. A dedicated international campaign of photometric observations, based on amateur-professional collaboration, was organized and coordinated by the IMCCE in order to catch several of these events. The set of the compiled observations is released in this work. We developed a relevant model of these events, including a topographic shape model of Kalliope refined in the present work, the orbit solution of Linus as well as the photometric effect of the shadow of one component falling on the other. By fitting this model to the only two full recorded events, we derived a new estimation of the equivalent diameter of Kalliope of 166.2+/-2.8km, 8% smaller than its IRAS diameter. As to the diameter of Linus, considered as purely spherical, it is estimated to 28+/-2 km. This substantial "shortening" of Kalliope gives a bulk density of 3.35+/-0.33g/cm3, significantly higher than past determinations but more consistent with its taxonomic type. Some constraints can be inferred on the composition.

description: Large non-saturating magnetoresistance has been observed in various materials and electron-hole compensation has been regarded as one of the main mechanisms. Here we present a detailed study of the angle-dependent Shubnikov -de Haas effect on large magnetoresistance material pyrite-type PtBi$_{2}$, which allows us to experimentally reconstruct its Fermi-surface structure and extract the physical properties of each pocket. We find its Fermi surface contains four types of pockets in the Brillouin zone: three ellipsoid-like hole pockets $α$ with C$_4$ symmetry located on the edges (M points), one intricate electron pocket $β$ merged from four ellipsoids along [111] located on the corners (R points), two smooth and cambered octahedrons $γ$ (electron) and $δ$ (hole) on the center ($Γ$ point). The deduced carrier densities of electrons and holes from the volume of pockets prove carrier compensation. This compensation at low temperatures is also supported by fitting the field dependence of Hall and magnetoresistance at different temperatures. We conclude that the compensation is the main mechanism for the large non-saturating magnetoresistance in pyrite-type PtBi$_{2}$. We found the hole pockets α may contribute major mobility because of their light masses and anisotropy to relatively avoid large-angle scattering at low temperature. This may be a common feature of semimetals with large magnetoresistance. The found sub-quadratic magnetoresistance in high field is probably due to field-dependent mobilities, another feature of semimetals under high magnetic fields.

description: This paper proposes a new non-oscillatory {\em energy-splitting} conservative algorithm for computing multi-fluid flows in the Eulerian framework. In comparison with existing multi-fluid algorithms in literatures, it is shown that the mass fraction model with isobaric hypothesis is a plausible choice for designing numerical methods for multi-fluid flows. Then we construct a conservative Godunov-based scheme with the high order accurate extension by using the generalized Riemann problem (GRP) solver, through the detailed analysis of kinetic energy exchange when fluids are mixed under the hypothesis of isobaric equilibrium. Numerical experiments are carried out for the shock-interface interaction and shock-bubble interaction problems, which display the excellent performance of this type of schemes and demonstrate that nonphysical oscillations are suppressed around material interfaces substantially.

title: Stability and Efficiency in Decentralized Two‐Sided Markets with Weak Preferences
Creators: name: Raykov, Radoslav
Publisher: name: Bank of Canada

description: Many decentralized markets are able to attain a stable outcome despite the absence of a central authority (Roth and Vande Vate, 1990). A stable matching, however, need not be efficient if preferences are weak. This raises the question whether a decentralized market with weak preferences can attain Pareto efficiency in the absence of a central matchmaker. I show that when agent tastes are independent, the random stable match in a large-enough market is asymptotically Pareto efficient even with weak preferences. In fact, even moderate-sized markets can attain good efficiency levels. The average fraction of agents who can Pareto improve is below 10% in a market of size n = 79 when one side of the market has weak preferences; when both sides have weak preferences, the inefficiency falls below 10% for n > 158. This implies that approximate Pareto efficiency is attainable in a decentralized market even in the absence of a central matchmaker.
description: Beaucoup de marchés décentralisés peuvent atteindre un état stable malgré l’absence d’autorité centrale (Roth et Vande Vate, 1990). Un jumelage stable, toutefois, n’a pas besoin d’être efficient si les préférences sont peu marquées. On peut dès lors se demander si un marché décentralisé caractérisé par des préférences peu marquées peut atteindre une efficience parétienne en l’absence d’un planificateur. L’auteur montre que, lorsque les goûts des agents économiques sont indépendants, le jumelage aléatoire stable dans un marché suffisamment important est efficient asymptotiquement au sens de Pareto même si les préférences sont peu marquées. En fait, les marchés de taille modeste peuvent eux aussi atteindre un degré d’efficience raisonnable. La proportion d’agents dont la situation est susceptible de s’améliorer au sens de Pareto est, en moyenne, inférieure à 10 % dans un marché de taille n = 79 lorsque les offreurs ou les demandeurs du marché ont des préférences peu marquées; si les deux groupes ont des préférences peu marquées, l’inefficience tombe au-dessous de 10 % pour n > 158. Ces résultats portent à croire qu’un marché décentralisé peut se rapprocher d’une efficience parétienne même en l’absence de planificateur.

description: L'ensemble de ces notes ont été crée par John Baldwin lors d'une de ses premières périodes de résidence à Paris. Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.
Les données ainsi que les images des fiches sont accessibles sur le site Internet à l'adresse suivante : http://studium-baldwin.lamop.fr/.
Les transcriptions des fiches ont été effectuées par des étudiants de Paris 1 Panthéon - Sorbonne mais elles n'ont pas été corrigées par la suite.

description: The decay $Z^{0}\rightarrow Q+ \ell^{+}\ell^{-}$, where $Q$ is a $J^{PC}=1^{--}$ quarkonium state, has a very clean final state, which should make it easy to detect. The branching ratio of this mode is greater than $10^{-6}$ for $ρ$, $ϕ$, and $ψ$, indicating that these processes may be detectable at LEP.

description: Matrix coordinate transformations are defined as substitution operators without requiring an ordering prescription or an inclusion function from the Abelian coordinate transformations. We construct transforming objects mimicking most of the properties of tensors. We point out some problems with the matrix generalization of contravariant vectors. We suggest to use the substitution operators to search for an inclusion function.

Form Factors for Integrable Lagrangian Field Theories, the Sinh-Gordon Model

description: Using Watson's and the recursive equations satisfied by matrix elements of local operators in two-dimensional integrable models, we compute the form factors of the elementary field $ϕ(x)$ and the stress-energy tensor $T_{μν}(x)$ of Sinh-Gordon theory. Form factors of operators with higher spin or with different asymptotic behaviour can easily be deduced from them. The value of the correlation functions are saturated by the form factors with lowest number of particle terms. This is illustrated by an application of the form factors of the trace of $T_{μν}(x)$ to the sum rule of the $c$-theorem.

title: Price-Level Dispersion versus Inflation-Rate Dispersion: Evidence from Three Countries
Creators: name: Fielding, David

description: Inflation can affect both the dispersion of commodity-specific price levels across locations (relative price variability, RPV) and the dispersion of inflation rates (relative inflation variability, RIV). Some menu-cost models and models of consumer search suggest that the RIV-inflation relationship could differ from the RPV-inflation relationship. However, most empirical studies examine only RIV, finding that RIV is high when inflation is high. We examine city-level retail price data from Japan, Canada and Nigeria, and find that the impact of inflation on RIV differs from its effect on RPV. In particular, positive inflation shocks reduce RPV but raise RIV.
description: L’inflation peut avoir un effet sur la dispersion des niveaux de prix de certains produits dans plusieurs régions du monde (variabilité des prix relatifs, VPR) et sur la dispersion des taux d’inflation (variabilité de l’inflation relative, VIR). D’après une partie des modèles de coûts d’affichage et des modèles de prospection qui illustrent les démarches des consommateurs, la relation entre inflation et VIR pourrait différer de la relation entre inflation et VPR. Or, la plupart des études empiriques sont focalisées sur la VIR : elles déterminent que la VIR est élevée quand l’inflation est forte. Nous nous intéressons à l’évolution des prix de détail dans un échantillon de villes japonaises, canadiennes et nigérianes. L’inflation a des effets différents sur la VIR et sur la VPR. En particulier, des chocs d’inflation positifs font baisser la VPR mais monter la VIR.
