title: Macroeconomics and asset pricing
Creators: name: Zhang, Yu
Publisher: name: University of Reading
Year: 2025

description: This thesis investigates asset pricing with macroeconomics. Chapter 1 gives an
overview of this thesis, including background, motivations and contributions. Chapter 2 documents the economic momentum effects in country-level equity indices. Momentum is a well-known and studied artefact of financial markets. In this paper, we
investigate whether momentum in a country’s macroeconomic variables is related to
the future performance of equities. We find that the past economic trends of a country’s fundamentals are positively associated with the equity market index returns,
termed the economic momentum effects. Based on that, an economic momentum
portfolio of buying (selling) equity index in countries with relatively strong (weak)
economic past trends exhibits an annualised Sharpe ratio of 0.87. The economic
momentum portfolio outperforms benchmarks regarding rewards to variability and
maximum drawdown and yields an annualised alpha of 3.5%
Chapter 3 examines the trading behaviour of noise traders in response to macro announcements. By employing direct and indirect proxies to capture their attention,
we show that noise traders’ market-concentrated attention on macro-announcement
days spills over to individual firms during post-macro-announcement periods, denoted as attention spillover effects. Both retail and institutional noise traders exhibit rising abnormal attention on stocks following the macro-announcements. Furthermore, we find that the attention spillover effects are more pronounced among
stocks without earnings announcements and are particularly noticeable in FOMC
announcements.
Chapter 4 examines the performance of equity options surrounding the scheduled meetings of the Federal Open Market Committee (FOMC). We document significant excess returns on equity options after the FOMC, denoted as the post-FOMC
drift, which the standard asset pricing models cannot explain. Upon investigating
the mechanisms, we find that this pattern is particularly pronounced in the context
of FOMC announcements accompanied by economic surprises, as investors tend to
overreact to such shocks. Additionally, we identify that options’ illiquidity plays a
significant role in driving this drift, as market participants demand higher expected
returns to compensate for the heightened illiquidity risk during post-FOMC periods. Furthermore, our analysis leads us to conclude that the observed drift is more
pronounced among put options than call options.
Lastly, Chapter 5 concludes the thesis and discusses future research.

description: The Interior Exploration using Seismic Investigations, Geodesy and Heat Transport mission, to be launched in 2018, will perform a comprehensive geophysical investigation of Mars in situ. The Seismic Experiment for Interior Structure package aims to detect global and regional seismic events and in turn offer constraints on core size, crustal thickness, and core, mantle, and crustal composition. In this study, we estimate the present‐day amount and distribution of seismicity using 3‐D numerical thermal evolution models of Mars, taking into account contributions from convective stresses as well as from stresses associated with cooling and planetary contraction. Defining the seismogenic lithosphere by an isotherm and assuming two end‐member cases of 573 K and the 1073 K, we determine the seismogenic lithosphere thickness. Assuming a seismic efficiency between 0.025 and 1, this thickness is used to estimate the total annual seismic moment budget, and our models show values between 5.7 × 1016 and 3.9 × 1019 Nm.

description: Nano-encapsulation is a technology used to pack substances in order to enhance their stability and bioavailability, but this packing may interact with living systems, causing unexpected toxicity. Vitamin A (vit A) is a substance that has received attention, because in developed countries, the increasing availability of supplements is leading to its excessive intake. This study aims to compare teratogenic effects caused by exposure to the traditional formulation of vit A versus nano-encapsulated vit A. We used ascidian embryos as an alternative model. Ascidians are marine organisms closely related to vertebrates that share with them a body plan and developmental programme, including the morphogenetic role of retinoic acid (RA). Our data showed that the adverse effects of exposure to the same concentration of the two formulations were different, suggesting that the nano-encapsulation increased the bioavailability of the molecule, which could be better absorbed and metabolised to RA, the effective teratogenic substance.

description: Im Jahre 2008 beging man das hundertjährige Jubiläum der archäologischen Ausgrabungen in der griechisch-römischen Stadt Ampurias. Gerade die damaligen Forschungen besaßen eine große kulturelle und symbolische Bedeutung für die Entwicklung und das Selbstverständnis Kataloniens zu Beginn des 20. Jhs. Der vorliegende Artikel macht nun jedoch darauf aufmerksam, dass die eigentlichen Anfänge der Erforschung der antiken Stadt sehr viel weiter zurückreichen. Konzentriert man sich bei der Betrachtung auf die durch öffentliche Stellen geförderten Maßnahmen – Freilegungen von privater Seite waren zu allen Zeiten üblich –, so begannen die wissenschaftlichen Grabungen bereits sieben Dekaden früher. Verantwortlich zeichnete die ‘Comisión de Monumentos de Girona’, die sich auf die finanzielle Hilfe der ‘Diputación provincial’ stützte.

description: Recurrent networks of dynamic elements frequently exhibit emergent collective oscillations, which can display substantial regularity even when the individual elements are considerably noisy. How noise-induced dynamics at the local level coexists with regular oscillations at the global level is still unclear. Here we show that a combination of stochastic recurrence-based initiation with deterministic refractoriness in an excitable network can reconcile these two features, leading to maximum collective coherence for an intermediate noise level. We report this behavior in the slow oscillation regime exhibited by a cerebral cortex network under dynamical conditions resembling slow-wave sleep and anaesthesia. Computational analysis of a biologically realistic network model reveals that an intermediate level of background noise leads to quasi-regular dynamics. We verify this prediction experimentally in cortical slices subject to varying amounts of extracellular potassium, which modulates neuronal excitability and thus synaptic noise. The model also predicts that this effectively regular state should exhibit noise-induced memory of the spatial propagation profile of the collective oscillations, which is also verified experimentally. Taken together, these results allow us to construe the enhanced regularity observed experimentally in the brain as an instance of collective stochastic coherence.

description: Citado por varios autores como un importante santuario rupestre, el lugar de Mogueira constituye un paradigma de las dificultades a las que nos enfrentamos al estudiar este tipo de lugares. Su excavación, realizada en 2009, permitió no sólo refutar la cronología castreña y romana para lo que se suponía un santuario rupestre y que en realidad es una fortificación medieval, sino también identificar el santuario que efectivamente existió, no en la cima del monte, como siempre se había pensado, sino junto a una línea de vaguada, relacionado con un pequeño arroyo, donde se sitúan varios grabados e inscripciones rupestres. En este trabajo se pretende contar lo que puede haber sido la verdadera historia del sitio de Mogueira a través de una rigurosa exposición de los datos arqueológicos.

description: En el año 1992 emprendí la restitución de la inscripción monumental de ambas caras del magnífico Acueducto de Segovia, formada por letras de bronce. Éstas fueron fijadas a los bloques de granito por medio de espigas y en épocas posteriores fueron desmontadas por lo que sólo se conservaron los agujeros de las espigas. El examen de estos paupérrimos restos de la inscripción como medio para reconstruir las letras, junto con las dificultades para acceder a la misma, a una altura de 20 m, constituyó en si mismo lo que podría llamarse una ‘aventura epigráfica’. Los resultados de esta empresa se publicaron ese mismo año en un informe provisional, pero el estudio detallado del acueducto no vio la luz hasta 1997. Este trabajo redactado en lengua alemana no se tradujo al español hasta el año 2010, cuando se editó como libro. Los resultados llamaron mucho la atención no sólo en el mundo científico, sino en círculos más amplios, sobre todo en España. La mayoría de los especialistas en epigrafía, arqueología e historia aceptaron los resultados presentados en la publicación; muchos de ellos con entusiamo, sobre todo los habitantes de Segovia. Sin embargo algunos especialistas fueron escépticos y manifestaron sus críticas, circunstancia que requería una respuesta. Al mismo tiempo, en el transcurso de los 20 años pasados desde la ‘aventura epigráfica’, la observación de las numerosas reconstrucciones con parecidas técnicas, de inscripciones del mundo romano, así como nuevos documentos epigráficos de la Hispania romana, y concretamente de la ciudad romana de Segovia, verifican la validez del método para restituir el texto y apoyan la argumentación dada. También aportan nuevos conocimientos sobre la técnica de restitución de inscripciones con letras de bronce, sobre las iniciativas imperiales para la construcción y renovación del acueducto y sobre su contexto histórico. Por todo ello es legítima la tarea de dedicar un nuevo artículo al Acueducto y su inscripción dos decenios después de la ‘aventura epigráfica’.

description: Die Untersuchung der Figurenfriese und Prozessionsdarstellungen auf westhispanischen Denkmälern zeigt deutlich, dass nahezu sämtliche Stücke unter römischem Einfluss entstanden sind. Ihre Entstehung kann also erst zu einem Zeitpunkt erfolgt sein, als die römische Kunst in der Region hinreichend bekannt war. Gleichwohl zeigt keine einzige Darstellung die Suovetaurilia in der bekannten, kanonisch römischen Ikonographie: Weder die Dreizahl der Tiere noch ihrer Rassen oder auch die Gottheit Mars, welche dieses Opfer üblicherweise erhält, sind stets vorhanden. Der Grund dafür mag darin liegen, dass es sich um ein altes Opfer aus indoeuropäischer Tradition handelt, das in Hispania seit Urzeiten vollzogen wurde, so dass die Darstellung in späterer, römischer Zeit nicht unbedingt dem stadtrömischen Kanon der Suovetaurilia folgen musste.

description: In this paper, we explain the nomination of ethnic minority candidates for lower house elections. We argue that these nominations are explained by the incentives that different parties face in different districts. Center-left parties reap greater electoral rewards when they offer descriptive representation, and that they also experience fewer difficulties in recruiting ethnic minority candidates. Therefore we argue that center-left parties have a greater incentive and ability to make their nominations more responsive to district demographics. More specifically, our hypothesis is that district-level ethnic diversity will increase the probability that any party will nominate an ethnic minority candidate, but this increase will be greatest for center-left parties. We look at multiple elections in Australia, the UK, and the US, and find consistent evidence in favor of this hypothesis. Even when center-left and center-right parties are nominating similar overall numbers of ethnic minority candidates, center-left parties’ descriptive representation patterns are more closely connected to district demographics. We argue that this helps explain how descriptive representation effects political competition more broadly.
Hölder continuity of Tauberian constants associated with discrete and ergodic strong maximal operators

Subjects: subject: Classical Analysis and ODEs (math.CA)

description: This paper concerns the smoothness of Tauberian constants of maximal operators in the discrete and ergodic settings. In particular, we define the discrete strong maximal operator $\tilde{M}_S$ on $\mathbb{Z}^n$ by \[ \tilde{M}_S f(m) := \sup_{0 \in R \subset \mathbb{R}^n}\frac{1}{\#(R \cap \mathbb{Z}^n)}\sum_{ j\in R \cap \mathbb{Z}^n} |f(m+j)|,\qquad m\in \mathbb{Z}^n, \] where the supremum is taken over all open rectangles in $\mathbb{R}^n$ containing the origin whose sides are parallel to the coordinate axes. We show that the associated Tauberian constant $\tilde{C}_S(α)$, defined by \[ \tilde{C}_S(α) := \sup_{\substack{E \subset \mathbb{Z}^n \\ 0 < \#E < \infty} } \frac{1}{\#E}\#\{m \in \mathbb{Z}^n:\, \tilde{M}_Sχ_E(m) > α\}, \] is Hölder continuous of order $1/n$. Moreover, letting $U_1, \ldots, U_n$ denote a non-periodic collection of commuting invertible transformations on the non-atomic probability space $(Ω, Σ, μ)$ we define the associated maximal operator $M_S^\ast$ by \[ M^\ast_{S}f(ω) := \sup_{0 \in R \subset \mathbb{R}^n}\frac{1}{\#(R \cap \mathbb{Z}^n)}\sum_{(j_1, \ldots, j_n)\in R}|f(U_1^{j_1}\cdots U_n^{j_n}ω)|,\qquad ω\inΩ. \] Then the corresponding Tauberian constant $C^\ast_S(α)$, defined by \[ C^\ast_S(α) := \sup_{\substack{E \subset Ω\\ μ(E) > 0}} \frac{1}{μ(E)}μ(\{ω\in Ω:\, M^\ast_Sχ_E(ω) > α\}), \] also satisfies $C^\ast_S \in C^{1/n}(0,1).$ We will also see that, in the case $n=1$, that is in the case of a single invertible, measure preserving transformation, the smoothness of the corresponding Tauberian constant is characterized by the operator enabling arbitrarily long orbits of sets of positive measure.

description: The DDI Alliance Technical Committee hosted a Webinar on February 2028, 2024 presenting the recently released DDI-Lifecycle 4.0 Beta 1.

DDI Lifecycle 4.0 is managed using a Model First development approach. Content additions and changes are added to the model and the serialization formats are automatically generated. The metadata content of DDI 3.3 has been converted into the new 4.0 model.

The ddi-lifecycle-4.0-beta.1.zip package includes:

schema.xsd - XML Schema

jsonSchema.json - JSON Schema

ddi4.xmi - OMG's UML XMI 2.5

ddi4.owl - RDF OWL (closed with restrictions)

ddi4.owl.ttl - RDF OWL (open)

ddi4.shex - ShEx

ddi4.shacl- SHACL

Other formats are also available but are not included in the official release. The beta package is available at: https://github.com/ddialliance/ddimodel/releases

The documentation for DDI Lifecycle 4.0 is also autogenerated from the model, and can be viewed at: https://ddialliance.github.io/ddimodel-web/

The Technical Committee is looking for feedback on the community's preference between the different OWL serializations and general comments about the XML and JSON. One version of the OWL models restrictions, the other is open and uses RDF shape languages to define rules. Ordering of lists in the OWL is handled using normal predicate relations combined with the addition of enumerable slots with index positions to keep the vocabularies in OWL-DL, we would like to hear the community's feedback on this approach to ordering as shown in the Sequence item type.

Los horrea eran edificios que requerían de una protección especial, pues estaban expuestos a grandes peligros, como los incendios, las plagas, la propia putrefacción del grano y los frecuentes robos. La amenaza que estos infortunios suponía para la población se explica por el hecho de que la base de la alimentación era el cereal y su ausencia provocaba el hambre. Como consecuencia de ello, no sólo se recurría a la protección de los graneros y las reservas de alimentos de un modo físico, sino que también se apelaba a las divinidades protectoras de las cosechas, del comercio y de los almacenes. Esta veneración tenía una dimensión pública notable, tal y como han puesto de manifiesto los textos y la documentación arqueológica, pero también se restringe al ámbito privado, pues la supervivencia y la prosperidad de la familia dependía enormemente de la buena conservación y protección de los alimentos.

description: In addition to the well known case of spherical coordinates the hydrogen atom separates in three further coordinate systems. Separating in a particular coordinate system defines a system of three commuting operators. We show that the joint spectrum of the Hamilton operator, and the $z$-components of the angular momentum and quantum Laplace-Runge-Lenz vectors obtained from separation in prolate spheroidal coordinates has quantum monodromy for energies sufficiently close to the ionization threshold. This means that one cannot globally assign quantum numbers to the joint spectrum. Whereas the principal quantum number $n$ and the magnetic quantum number $m$ correspond to the Bohr-Sommerfeld quantization of globally defined classical actions a third quantum number cannot be globally defined because the third action is globally multi valued.

description: Large eddy simulations (LES) are a powerful tool in understanding processes that are inaccessible by direct simulations due to their complexity, for example, in the highly turbulent regime. However, their accuracy and success depends on a proper subgrid-scale (SGS) model that accounts for the unresolved scales in the simulation. We evaluate the applicability of two traditional SGS models, namely the eddy-viscosity (EV) and the scale-similarity (SS) model, and one recently proposed nonlinear (NL) SGS model in the realm of compressible MHD turbulence. Using 209 simulations of decaying, supersonic (initial sonic Mach number of ~3) MHD turbulence with a shock-capturing scheme and varying resolution, SGS model and filter, we analyze the ensemble statistics of kinetic and magnetic energy spectra and structure functions. Furthermore, we compare the temporal evolution of lower and higher order statistical moments of the spatial distributions of kinetic and magnetic energy, vorticity, current density, and dilatation magnitudes. We find no statistical influence on the evolution of the flow by any model if grid-scale quantities are used to calculate SGS contributions. In addition, the SS models, which employ an explicit filter, have no impact in general. On the contrary, both EV and NL models change the statistics if an explicit filter is used. For example, they slightly increase the dissipation on the smallest scales. We demonstrate that the nonlinear model improves higher order statistics already with a small explicit filter, i.e. a three-point stencil. The results of e.g. the structure functions or the skewness and kurtosis of the current density distribution are closer to the ones obtained from simulations at higher resolution. We conclude that the nonlinear model with a small explicit filter is suitable for application in more complex scenarios when higher order statistics are important.

Validated quantitative analysis show that syringin (2.52%) and rutin (1.13%) are the main phenolic compounds in bark and leaf, respectively. Notable radical scavenging and antinociceptive activities of the bark and leaf extracts were confirmed by in vitro DPPH● and ABTS●+ assays and by in vivo hot-plate method in mice, respectively. Our results could lay the scientific basic of future clinical perspectives of lilac bark and leaf.

description: Für die neuen Forschungen wurde der Südteil des Lagers V ausgewählt und geomagnetisch begangen. Diese Prospektion im Jahre 2009 hatte zum Ziel, die Eignung des angewandten Verfahrens für eine Erkundung des gesamten, rund 60 ha großen Lagergeländes zu überprüfen. Die Größe der hierzu untersuchten Fläche betrug 3,6 ha. Die Messungen wurden für den Testzweck mit einem größeren Raster als üblich durchgeführt, erbrachten aber dennoch den Nachweis von zahlreichen römischen Strukturen, die als Mauerzüge von Gebäuden interpretiert werden können. In einem ausgewählten Teilbereich erfolgte 2010 eine Testgrabung. Es gelang dabei die Dokumentation von mehreren römischen Mauerzügen, die teilweise noch überraschend gut erhalten waren und eindeutig mit Grabungsbefunden der Untersuchungen unter der Leitung von Schulten 1911/12 in Übereinstimmung gebracht werden konnten. Allerdings müssen nun die damals gemachten Angaben erheblich modifiziert werden. Auch die Suchschnitte der damaligen Ausgrabungen waren nachweisbar.

description: We consider evolving networks in which each node can have various associated properties (a state) in addition to those that arise from network structure. For example, each node can have a spatial location and a velocity, or some more abstract internal property that describes something like social trait. Edges between nodes are created and destroyed, and new nodes enter the system. We introduce a "local state degree distribution" (LSDD) as the degree distribution at a particular point in state space. We then make a mean-field assumption and thereby derive an integro-partial differential equation that is satisfied by the LSDD. We perform numerical experiments and find good agreement between solutions of the integro-differential equation and the LSDD from stochastic simulations of the full model. To illustrate our theory, we apply it to a simple continuum model for osteocyte network formation within bones, with a view to understanding changes that may take place during cancer. Our results suggest that increased rates of differentiation lead to higher densities of osteocytes but with a lower number of dendrites. To help provide biological context, we also include an introduction to osteocytes, the formation of osteocyte networks, and the role of osteocytes in bona metastasis.

description: This paper presents the discovery of the oldest Roman camp on the Iberian Peninsula, a camp from the Second Punic War situated in La Palma (Tarragona, Spain), by the mouth of the River Ebro. Although no structural remains have been found, the site’s strategic interest along with many coins, arms and fragments of amphoras and other objects indicate that a military camp was established here between 218 and 209 BC. Written sources, mainly Polybius and Livy, suggest that La Palma was where the legions of Publius Cornelius Scipio gathered before the attack on Carthago Nova in 209 BC. The paper ends by suggesting that La Palma may be the Roman camp of Nova Classis mentioned by Livy during the events of the war in 217 BC.

description: The aim of the present work is an attempt to define computable measure of similarity between different endpoints. The similarity of structural alerts of different biochemical endpoints can be used to solve tasks of medicinal chemistry. Optimal descriptors are a tool to build up models for different endpoints. The optimal descriptor is calculated with simplified molecular input-line entry system (SMILES). A group of elements (single symbol or pair of symbols) can represent any SMILES. Each element of SMILES can be represented by so-called correlation weight i.e. coefficient that should be used to calculate descriptor. Numerical data on the correlation weights are calculated by the Monte Carlo method, i.e. by optimization procedure, which gives maximal correlation coefficient between the optimal descriptor and endpoint for the training set. Statistically stable correlation weights observed in several runs of the optimization can be examined as structural alerts, which are promoters of the increase or the decrease of a biochemical activity of a substance. Having data on several runs of the optimization correlation weights, one can extract list of promoters of increase and list of promoters of decrease for an endpoint. The study of similarity and dissimilarity of the above lists has been carried out for the following pairs of endpoints: (i) mutagenicity and anticancer activity; (ii) mutagenicity and blood brain barrier; and (iii) blood brain barrier and anticancer activity. The computational experiment confirms that similarity and dissimilarity for pairs of endpoints can be measured.

description: Upcoming HI surveys will deliver such large datasets that automated processing using the full 3-D information to find and characterize HI objects is unavoidable. Full 3-D visualization is an essential tool for enabling qualitative and quantitative inspection and analysis of the 3-D data, which is often complex in nature. Here we present $\tt{SlicerAstro}$, an open-source extension of 3DSlicer, a multi-platform open source software package for visualization and medical image processing, which we developed for the inspection and analysis of HI spectral line data. We describe its initial capabilities, including 3-D filtering, 3-D selection and comparative modelling.

description: We investigate the feasibility of detecting water molecules (H2O) and water ions (H20+) from the Europa plumes from a flyby mission. A Monte Carlo particle tracing method is used to simulate the trajectories of neutral particles under the influence of Europa's gravity field and ionized particles under the influence of Jupiter's magnetic field and the convectional electric field. As an example mission case we investigate the detection of neutral and ionized molecules using the Particle Environment Package (PEP), which is part of the scientific payload of the future JUpiter ICy moon Explorer mission (JUICE). We consider plumes that have a mass flux that is three orders of magnitude lower than what has been inferred from recent Hubble observations (Roth et al., 2014a). We demonstrate that the in-situ detection of H2O and H2O+ from these low mass flux plumes is possible by the instruments with large margins with respect to background and instrument noise. The signal to noise ratio for neutrals is up to ~5700 and ~33 for ions. We also show that the geometry of the plume source, either a point source or 1000 km-long crack, does not influence the density distributions, and thus, their detectability. Furthermore, we discuss how to separate the plume-originating H2O and H2O+ from exospheric H2O and H2O+ . The separation depends strongly on knowledge of the density distribution of Europa's exosphere.

description: We investigate a generalized spherical means operator, viz. generalized spherical mean Radon transform, acting on radial functions. We establish an integral representation of this operator and find precise estimates of the corresponding kernel. As the main result, we prove two-weight mixed norm estimates for the integral operator, with general power weights involved. This leads to weighted Strichartz type estimates for solutions to certain Cauchy problems for classical Euler-Poisson-Darboux and wave equations with radial initial data.

description: The gravitational waves emitted by binary systems with extreme mass ratios carry unique astrophysical information expected to be probed by the next generation of gravitational wave detectors such as LISA. The detection of these binaries rely on an accurate modeling of the gravitational self-force that drives their orbital evolution. Although the theoretical formalism to compute the self-force has been largely established, the mathematical tools needed to implement it are still under development, and the self-force computation remains an open problem. We present here a frequency-domain implementation of the particle-without-particle (PwP) technique previously developed for the computation of the scalar self-force -- a helpful testbed for the gravitational self-force.

description: The growth of digital creative industries has received increasing interest in economic geography, but our knowledge of factors shaping the longer-term growth and decline of digital creative industry clusters remains limited. We address this issue through a longitudinal case study of the Japanese video game software industry during the last three decades. Drawing on a theoretical framework emphasizing the link between differentiation of game intellectual properties (IPs) and competitiveness in creative industries, we suggest that an important role in the growth and subsequent decline of the Japanese video game industry could be attributed to enabling and constraining changing technological and market conditions related to the Japanese cluster’s ability to produce differentiated game IPs. A previously highly competitive system lost much of its competitiveness. Technological change in the industry made it difficult for the Japanese cluster to maintain previous levels of differentiation when facing increasing development costs and less cross-sectoral cultural skill transfer.
