Financial Intermediation, Heterogeneous Investors, and Asset Pricing

description: This dissertation consists of three essays in financial intermediation, heterogeneous agents, and asset pricing. In the first essay, I extract mutual fund flows that respond to the active change in equity share of mutual funds and show that they have significant predictability of market return. These “market timing-sensitive (MT-sensitive) flows” have predictability of the overall market over the next two to twelve months, without evidence of reversal. This predictability holds even when controlling for other macroeconomic variables and market sentiment index. I report that mutual fund managers who enjoy MT-sensitive inflows outperform the managers with MT-sensitive outflows over the next quarter. Also, I show that investors whose mutual fund investments mimic MT-sensitive flows have market timing ability, and outperform investors with mutual fund investments in the opposite direction to MT-sensitive flows.
      In the second essay, I analyze mutual fund investors' responses to changes in funds' allocations to emerging markets. I show that such flows predict positive abnormal returns in emerging markets at quarterly and annual horizons. When there is one standard deviation shock to the EMT-sensitive flows, a six-month equal-weighted emerging market return is expected to be 3.58% in excess of risk-free rate in the US, and 1.69% in excess of US stock market excess return. This predictability holds even when controlling for other macroeconomic variables. The evidence suggests fund investors collectively possess valuable information about emerging markets.
      The third essay proposes a general equilibrium model with bounded rationality that explains both endogenous learning and price. If agents are bounded rational, in that they do not have complete processing capacity as assumed in rational expectations models, there is a role for endogenous allocation of resources to learning about the economy. Investors trade off learning about different elements, such as terminal dividend (asset fundamental) vs. market structure (aggregate demand schedules). I found that investors prefer to learn what others do not learn, and this explains why there is specialization in the investment. Investors tend to be fundamentalists when market is uncertain, but learning also depends on capacity, ratio of sophisticated investors, risk aversion, etc. I analyze the trade-off between these information sources, and the implications for price efficiency, risk, and return, in a general equilibrium.

description: Sequence transformations are important tools for the convergence acceleration of slowly convergent scalar sequences or series and for the summation of divergent series. Transformations that depend not only on the sequence elements or partial sums $s_n$ but also on an auxiliary sequence of so-called remainder estimates $ω_n$ are of Levin-type if they are linear in the $s_n$, and nonlinear in the $ω_n$. Known Levin-type sequence transformations are reviewed and put into a common theoretical framework. It is discussed how such transformations may be constructed by either a model sequence approach or by iteration of simple transformations. As illustration, two new sequence transformations are derived. Common properties and results on convergence acceleration and stability are given. For important special cases, extensions of the general results are presented. Also, guidelines for the application of Levin-type sequence transformations are discussed, and a few numerical examples are given.

description: As service robots become more general-purpose, they will need to adapt to their users' preferences over a large set of all possible tasks that they can perform. This includes preferences regarding which actions the users prefer to delegate to robots as opposed to doing themselves. Existing personalization approaches require task-specific data for each user. To handle diversity across all household tasks and users, and nuances in user preferences across tasks, we propose to learn a task adaptation function independently, which can be used in tandem with any universal robot policy to customize robot behavior. We create Task Adaptation using Abstract Concepts (TAACo) framework. TAACo can learn to predict the user's preferred manner of assistance with any given task, by mediating reasoning through a representation composed of abstract concepts built based on user feedback. TAACo can generalize to an open set of household tasks from small amount of user feedback and explain its inferences through intuitive concepts. We evaluate our model on a dataset we collected of 5 people's preferences, and show that TAACo outperforms GPT-4 by 16% and a rule-based system by 54%, on prediction accuracy, with 40 samples of user feedback.

description: L' Agenzia Nazionale di Valutazione del sistema Universitario e della Ricerca (ANVUR) può essere considerata un'autorità indipendente dal potere esecutivo? I suoi membri esprimono libere idee scientifiche sulla valutazione od opinioni di funzionari amministrativi gerarchicamente sottoposti al potere esecutivo?

Alla prima domanda si deve rispondere in senso negativo: ANVUR non è un'autorità indipendente dal potere esecutivo, è piuttosto un'agenzia dipendente dal potere del Ministero dell'Università e della Ricerca (MUR).

Al secondo quesito occorre rispondere che i funzionari dell'agenzia, quando esprimono idee sulla valutazione e sulla stessa agenzia, non godono della libertà e dell'autonomia di altre categorie di soggetti come i professori e i ricercatori universitari.

description: Detecting obstructive sleep apnea (OSA) is essential for diagnosing and managing sleep health. Traditionally, this involves clinical settings with hardly accessible processes. We propose that the automated detection of OSA events is achievable using features extracted from fingertip photoplethysmography (PPG) signals combined with modern deep learning (DL) techniques. Utilizing two benchmark data sets with extensive PPG recordings, we introduce ApSense, a DL model designed for the OSA event onset recognition from PPG features. ApSense presents a custom neural architecture and domain-specific feature extraction from PPG waveforms. We benchmark it against the state-of-the-art (SOTA) algorithms, including RRWaveNet, PPGNetSA, AIOSA, DRIVEN, and LeNet-5. In our evaluations, ApSense demonstrated improved sensitivity, specificity, and area under the receiver operating characteristic (AUROC) on the test data sets. Furthermore, an ablation study highlighted strategic customizations of ApSense, enhancing its performance and adaptability to different data sets. ApSense demonstrates high reliability, as its outstanding results were confirmed even in high-variance data sets. By detecting OSA events, ApSense enables the estimation of the predicted apnea-hypopnea index (pAHI), which can be used for prescreening individuals for sleep apnea in a low-cost setup. ApSense shows the potential for the PPG-based OSA detection and clinical applications for prescreening in the future.

description: In this study, we provide a full experimental characterization of the parametric longitudinal coupling between a CMOS charge qubit and an off-chip RF resonator. Following Corrigan et al, Phys. Rev. Applied 20, 064005 (2023), we activate parametric longitudinal coupling by driving the charge qubit at the resonator frequency. Managing the crosstalk between the drive applied to the qubit and the resonator allows for the systematic study of the dependence of the longitudinal and dispersive charge-photon couplings on the qubit-resonator detuning and the applied drive. Our experimental estimations of the charge-photon couplings are perfectly reproduced by theoretical simple formulas, without relying on any fitting parameter. We go further by showing a parametric displacement of the resonator's steady state, conditional on the qubit state, and the insensitivity of the longitudinal coupling constant on the photon population of the resonator. Our results open to the exploration of the photon-mediated longitudinal readout and coupling of multiple and distant spins, with long coherent times, in hybrid CMOS cQED architectures.

description: We investigate thick-brane solutions within the five-dimensional bumblebee gravity in the presence of a real scalar field. Specifically, we implement the Lorentz symmetry breaking scenario within this context and obtain brane-like structures. Since the contribution of the bumblebee field is expected to be weak, we solve the field equations in the small-parameter regime. In this situation, we develop a first-order framework to describe the brane. The results show that the function which drives the bumblebee field may engender a lumplike structure whose shape depends on the parameters. On one hand, the effect of the non-minimal coupling, controlled by $ξ$, between the bumblebee field and gravity shifts the field from the vacuum expectation value. On the other hand, the aether parameter, $β$, is responsible for modifying the solution inside the brane.

description: Large assemblies of nonlinear dynamical units driven by a long-wave fluctuating external field are found to generate strong turbulence with scaling properties. This type of turbulence is so robust that it persists over a finite parameter range with parameter-dependent exponents of singularity, and is insensitive to the specific nature of the dynamical units involved. Whether or not the units are coupled with their neighborhood is also unimportant. It is discovered numerically that the derivative of the field exhibits strong spatial intermittency with multifractal structure.

Phraseological units, including idioms, proverbs, and set expressions, play a significant role in both languages and carry deep cultural and linguistic meaning. The study investigates the similarities and differences between the two languages in terms of the meanings and usages of these units. Additionally, the paper explores how cultural, historical, and social factors influence the formation and interpretation of phraseological units in English and Uzbek. Effective strategies for teaching and translating phraseological units between these two languages are also discussed.

description: Revegetation trials were established in 1979 on BP Canada's Sukunka Coal property in the Northeast Coal Block. The trials were designed to test the effects of four levels of fertilizer application on alpine revegetation and to determine the optimum fertilizer treatments for revegetation of subalpine disturbances. The use of native species grown from locally collected seed was also tested in both alpine and subalpine environments. Field assessments were undertaken in August 1980 and 1981. In the alpine the greatest first year response to fertilization was on xeric sites. Heavy first year growth resulted in excessive mulching retarding second year emergence. In the subalpine heavy fertilization resulted in reduced legume establishment, thus, reducing second year cover. Establishment of native species in the alpine was very poor while there was a good establishment in the subalpine. Further assessments are planned as part of BP Canada's ongoing reclamation research program.

Since these sequences can then be described as model sets with ell-adic internal space, we add an approach to ``visualize'' such internal spaces.

Subjects: subject: Competency-Based Assessment

description: Assessment in Vocational Education and Training (VET) is complex and contentious. Assessment policies and practices in VET have been the subject of much debate over the last twenty years. A number of registered training organisations supplemented the traditional competency-based assessment model with graded assessment in the early 2000s, only to reverse their assessment policy in recent years. Debate about assessment practices within VET is often focussed on the technical or policy implications, rather than the lived experiences of students. Research about assessment in Arts courses within the VET sector offers a sound focal point for investigation. The focus of the research reported here is a VET creative arts capstone unit of work, where students were asked to produce assessment submissions that evidence the full extent of their skills and knowledge acquired throughout the course. This research examines how two different assessment models – competency-based assessment and graded assessment – are experienced by a specific cohort of students undertaking a final capstone unit in an Advanced Diploma of Visual Arts (Focus on Photography) course offered at a TAFE Institute in Queensland. Using a phenomenological lens this research explores the lived experiences of six students whose photographic work was evaluated through both assessment processes. The findings show each student’s assessment experience to be different, though all research participants found graded assessment to be a more worthwhile experience. The graded assessment approach also had a positive impact on participants’ confidence and identity as emerging professional photographers. The findings of this research could be used to inform VET educators how they might approach assessment to create a better overall experience for students, and add to evidence on the student experience of different assessment models, which could be considered for assessment policy review.

description: The analogy between frictional cracks, propagating along interfaces in frictional contact, and ordinary cracks in bulk materials is important in various fields. We consider a stress-controlled frictional crack propagating at a velocity $c_{\rm r}$ along an interface separating two strips, each of height $H$, the frictional counterpart of the classical problem of a displacement-controlled crack in a strip, which played central roles in understanding material failure. We show that steady-state frictional cracks in a strip geometry require a nonmonotonic dependence of the frictional strength on the slip velocity and, in sharp contrast to their classical counterparts, feature a vanishing stress drop. Here, rupture is driven by energy flowing to its edge from behind, generated by an excess power of the external stress, and to be accompanied by an increase in the stored elastic energy, in qualitative contrast to the classical counterpart that is driven by the release of elastic energy stored ahead of the propagating edge. Finally, we derive a complete set of mesoscopic and macroscopic scaling relations for frictional cracks in a strip geometry and demonstrate that the stress singularity near their edges is proportional to $(Δ{v}/c_{\rm r})\sqrt{H}$, where $Δ{v}$ is the slip velocity rise accompanying their propagation.

description: Evaluating, ranking, and clustering (ERC) stand as fundamental tasks in scientific research, each requiring a mathematical foundation. This study presents an ERC system anchored in the CCHZ-DISO system.

Previous research underscores the optimality achieved by the CCHZ-DISO system (Hu et al., 2022). Since the inception of CCHZ-DISO-series research by Hu et al. (2019), DISO has found extensive applications across various domains including geography, hydrology, and economics. Analogous to the CCHZ-DISO system's construction, the ERC system employs the Euclidean distance to perform evaluating, ranking, and clustering tasks.

Furthermore, illustrative examples are provided to elucidate the application of the ERC system. In fact, the ERC system unified the evaluating, ranking, and clustering tasks in one simple equation which is more flexible and simpler than the present system. It will have a more widely application than CCHZ-DISO in diverse scientific domains.

We consider the sine-Gordon/massive Thirring model (sG/mT) in a periodic box of length $L$ using the light-cone approach, in which the sG/mT model is obtained as the continuum limit of an inhomogeneous six vertex model. This NLIE is an useful starting point to compute the spectrum of excited states both analytically in the large $L$ (perturbative) and small $L$ (conformal) regimes as well as numerically.

description: Model sets (also called cut and project sets) are generalizations of lattices, and multi-component model sets are generalizations of lattices with colourings. In this paper, we study self-similarities of multi-component model sets. The main point may be simply summarized: whenever there is a self-similarity, there are also naturally related density functions. As in the case of ordinary model sets, we show that invariant densities exist and that they produce absolutely continuous invariant measures in internal space, these features now appearing in matrix form. We establish a close connection between the theory of invariant densities and the spectral theory of matrix continuous refinement operators.

description: At the intersection of quantum theory and relativity lies the possibility of a clock experiencing a superposition of proper times. We consider quantum clocks constructed from the internal degrees of relativistic particles that move through curved spacetime. The probability that one clock reads a given proper time conditioned on another clock reading a different proper time is derived. From this conditional probability distribution, it is shown that when the center-of-mass of these clocks move in localized momentum wave packets they observe classical time dilation. We then illustrate a quantum correction to the time dilation observed by a clock moving in a superposition of localized momentum wave packets that has the potential to be observed in experiment. The Helstrom-Holevo lower bound is used to derive a proper time-energy/mass uncertainty relation.

Financing The Health Care Safety Net: How Federalism And Medicaid's Funding Formula Shape State Budgets And American Welfare

description: This dissertation explores the political development of Medicaid financing, specifically its federal-state cost sharing formula. This dissertation traverses a half-century of congressional policymaking and an original 30-year dataset of state-level Medicaid expenditure and enrollment figures to provide a positivist account of how the federal and state governments' shared financial responsibilities for Medicaid affect overall Medicaid expenditures and state budget priorities. This dissertation also considers the direct and indirect financial burden that Medicaid's costs impose on taxpayers--both in their capacity as Americans and as residents of individual states.
      This dissertation argues that the growth in Medicaid costs is attributed to the resiliency of a funding formula that subsidizes the states' policies and redistributes liability for Medicaid expenditures between the states and federal governments. By subsidizing the costs of a state's Medicaid program, a state's Federal Medical Assistance Percentage (FMAP) reduces the effective fiscal burden of its Medicaid policies, thereby incentivizing policymakers to expand Medicaid beyond what is warranted by the policy preference of the state's residents. As a result, state budgets are likely to reflect an intentionally inefficient, yet politically rational, allocation of public resources. Compounded over decades, and exasperated by more recent adjustments that reduce the states' direct fiscal responsibilities for their Medicaid policies, the fiscal imperative imposed by Medicaid's financing institution has compelled states to maintain a rate of growth in Medicaid expenditures that now threatens to overwhelm the states' ability to adequately fund its other public commitments.
Real Time Quarkonium Transport Coefficients in Open Quantum Systems from Euclidean QCD

description: Recent open quantum system studies showed that quarkonium time evolution inside the quark-gluon plasma is determined by transport coefficients that are defined in terms of a gauge invariant correlator of two chromoelectric field operators connected by an adjoint Wilson line. We study the Euclidean version of the correlator for quarkonium evolution and discuss the extraction of the transport coefficients from this Euclidean correlator, highlighting its difference from other problems that also require reconstructing a spectral function, such as the calculation of the heavy quark diffusion coefficient. Along the way, we explain why the transport coefficient $γ_{\rm adj}$ differs from $γ_{\rm fund}$ at finite temperature at $\mathcal{O}(g^4)$, in spite of the fact that their corresponding spectral functions differ only by a temperature-independent term at the same order. We then discuss how to evaluate the Euclidean correlator via lattice QCD methods, with a focus on reducing the uncertainty caused by infrared renormalons in determining the renormalization factor nonperturbatively.

Riemannian theory of Hamiltonian chaos and Lyapunov exponents

description: This paper deals with the problem of analytically computing the largest Lyapunov exponent for many degrees of freedom Hamiltonian systems. This aim is succesfully reached within a theoretical framework that makes use of a geometrization of newtonian dynamics in the language of Riemannian geometry. A new point of view about the origin of chaos in these systems is obtained independently of homoclinic intersections. Chaos is here related to curvature fluctuations of the manifolds whose geodesics are natural motions and is described by means of Jacobi equation for geodesic spread. Under general conditions ane effective stability equation is derived; an analytic formula for the growth-rate of its solutions is worked out and applied to the Fermi-Pasta-Ulam beta model and to a chain of coupled rotators. An excellent agreement is found the theoretical prediction and the values of the Lyapunov exponent obtained by numerical simulations for both models.

description: In 2023, the 12th edition of Global Trajectory Competition was organised around the problem referred to as "Sustainable Asteroid Mining". This paper reports the developments that led to the solution proposed by ESA's Advanced Concepts Team. Beyond the fact that the proposed approach failed to rank higher than fourth in the final competition leader-board, several innovative fundamental methodologies were developed which have a broader application. In particular, new methods based on machine learning as well as on manipulating the fundamental laws of astrodynamics were developed and able to fill with remarkable accuracy the gap between full low-thrust trajectories and their representation as impulsive Lambert transfers. A novel technique was devised to formulate the challenge of optimal subset selection from a repository of pre-existing optimal mining trajectories as an integer linear programming problem. Finally, the fundamental problem of searching for single optimal mining trajectories (mining and collecting all resources), albeit ignoring the possibility of having intra-ship collaboration and thus sub-optimal in the case of the GTOC12 problem, was efficiently solved by means of a novel search based on a look-ahead score and thus making sure to select asteroids that had chances to be re-visited later on.

description: The increasing use and cost of high performance computing (HPC) requires new easy-to-use tools to enable HPC users and HPC systems engineers to transparently understand the utilization of resources. The MIT Lincoln Laboratory Supercomputing Center (LLSC) has developed a simple command, LLload, to monitor and characterize HPC workloads. LLload plays an important role in identifying opportunities for better utilization of compute resources. LLload can be used to monitor jobs both programmatically and interactively. LLload can characterize users' jobs using various LLload options to achieve better efficiency. This information can be used to inform the user to optimize HPC workloads and improve both CPU and GPU utilization. This includes improvements using judicious oversubscription of the computing resources. Preliminary results suggest significant improvement in GPU utilization and overall throughput performance with GPU overloading in some cases. By enabling users to observe and fix incorrect job submission and/or inappropriate execution setups, LLload can increase the resource usage and improve the overall throughput performance. LLload is a light-weight, easy-to-use tool for both HPC users and HPC systems engineers to monitor HPC workloads to improve system utilization and efficiency.

description: The electronic structure and photophysical properties of three iridium(III) complexes bearing tridentate chromophoric chelate have been theoretically studied by using the DFT/TDDFT. The lowest lying singlet→singlet absorptions of all studied complexes are respectively located at 363 nm, 394 nm and 353 nm. The calculated emission wavelengths for all studied complexes are 503 nm, 486 nm and 493 nm, respectively. The calculated results show that the electron-accepting and electron-donating substituent groups have the important effect on the electronic structure and photophysical properties of all studied iridium complexes with tridentate ligands.
