description: This paper analyses the time consistency of open-loop equilibria, in the cases
of Nash and Stackelberg behaviour. We define a class of games where the
strong time-consistency of the open-loop Nash equilibrium associates with
the time consistency of the open-loop Stackelberg equilibrium. We label
these games as ‘perfect uncontrollable’. We provide one example based on a
model of oligopolistic competition in advertising efforts. We also present two
oligopoly games where one property holds while the other does not, so that
either (i) the open-loop Nash equilibrium is subgame perfect while the stackelberg
one is time inconsistent, or (ii) the open-loop Nash and Stackelberg
equilibria are only weakly time consistent.

description: We examine the endogenous choice between price and quantity behaviour
in a duopoly supergame with product differentiation. We find
that (i) if cartel profits are evenly split between firms, then only symmetric
equilibria obtains; (i) if instead the additional profits available
through collusion are split according to the Nash bargaining solution,
there are parameter regions where all subgame perfect equilibria are
asymmetric, with firms colluding in price-quantity supergames.

Optimal monetary policy in a simple distorted economy

Subjects: SECS-P/06 Economia applicata

description: In this paper I search for an optimal con�gurations of parameters for
variants of the Taylor rule by using an Accurate Second-Order Welfare based method within
a fully microfounded Dynamic Stochastic model, with price rigidities, without capital accu-
mulation. Money is inserted via a transaction cost function, price rigidities are modelled
via quadratic cost of price adjustment. A version of the model with distortionary taxation is
also explicitly tested. The model is solved up to Second Order solution. Optimal rules are
obtained by maximizing a conditional welfare measure, di¤erently from what has been done
in the current literature. Optimal monetary policy functions turn out to be characterized by
in�ation targeting parameter lower than in empirical studies. In general, the optimal values
for moentary policy parameters depend from the degree of nominal rigidities and from the role
of �scal policy. When nominal rigidities are higher, optimal monetary policy becomes more
aggressive towards in�ation. With a tigther �scal policy, optimal monetary policy turns out to
be less in�ation-aggressive. Moreover, the results show that relying conditional welfare mea-
sure avoids the problems related with �rst-order or unconditional welfare measures. Impulse
Response functions based on second order model solution show a non-a¢ ne pattern when the
economy is hit by shocks of di¤erent magnitude.

description: We present and analyze $F_σ$-Mathias forcing, which is similar but tamer than Mathias forcing. In particular, we show that this forcing preserves certain weak subsystems of second-order arithmetic such as $\mathsf{ACA}_0$ and $\mathsf{WKL}_0 + \mathsf{I}Σ^0_2$, whereas Mathias forcing does not. We also show that the needed reals for $F_σ$-Mathias forcing (in the sense of Blass) are just the computable reals, as opposed to the hyperarithmetic reals for Mathias forcing.

description: A key feature of the EU harmonization of technical barriers to trade (TBT’s) is that exporting firms may entail a compliance costs. This paper provides theoretical and empirical work. In a simple Cournot duopoly with trade, we pursue the idea that process R&D has a positive spillover effect (with different intensities) in lowering the compliance cost and investigate the impact of an R&D subsidy. Using a self-constructed database, which specifically identifies sectors where the EU has sought to introduce harmonized environmental regulations, we find evidence that support this prediction of the theory.
Topological flat band models with arbitrary Chern numbers

description: We report the theoretical discovery of a systematic scheme to produce topological flat bands (TFBs) with arbitrary Chern numbers. We find that generically a multi-orbital high Chern number TFB model can be constructed by considering multi-layer Chern number C=1 TFB models with enhanced translational symmetry. A series of models are presented as examples, including a two-band model on a triangular lattice with a Chern number C=3 and an $N$-band square lattice model with $C=N$ for an arbitrary integer $N$. In all these models, the flatness ratio for the TFBs is larger than 30 and increases with increasing Chern number. In the presence of appropriate inter-particle interactions, these models are likely to lead to the formation of novel Abelian and Non-Abelian fractional Chern insulators. As a simple example, we test the C=2 model with hardcore bosons at 1/3 filling and an intriguing fractional quantum Hall state is observed.

description: We investigate a dynamic Cournot duopoly with intraindustry trade, where firms invest in R&D to reduce the level of iceberg transportation costs. We adopt both open-loop and closed-loop equilibrium concepts, showing that a unique (saddle point) steady state exists in both cases. In the open-loop model, optimal investments and the resulting efficiency of transportation technology are independent of the relative size of the two countries. On the contrary, in the closed-loop case, a home market effect operates so that thefirm located in the larger country invests more than the rival located in the smaller one. Policy implications are also evaluated.
Gibrat’s law and market selection in the radio, tv & telecommunications equipment industry

Subjects: SECS-P/02 Politica economica

description: According to Gibrat’s Law of Proportionate Effect, the growth rate of a given firm is independent of its size at the beginning of the period examined. In contrast to the previous literature on the subject, this paper seeks to test the Law by taking account of both the entry process and the role of survival/failure in reshaping a given population of firms over time. It does so by focusing on the entire population of firms (including newborn ones) in the Italian Radio, TV & Telecommunications equipment industry and tracking them over seven years. Consistently with the previous literature, it finds that - in general - Gibrat’s Law is to be rejected, since smaller firms tend to grow faster than their larger counterparts. However, the paper’s main finding is that this rejection of Gibrat’s Law may be due to market dynamics and selection. In other words, it is due to the entry process and the presence of transient smaller firms. Indeed, whilst it is found that Gibrat’s Law has to be rejected over a seven-year period during which both incumbent and newborn firms are considered, for both sub-populations of surviving firms a convergence towards Gibrat-like behavior over time can be detected. Thus, market selection "cleans" the original population of firms and the resulting industrial "core" (mature, larger, well-established and most efficient firms) does not seem to depart from a Gibrat-like pattern of growth.

description: In a three-dimensional Fermi liquid, quasiparticles near the Fermi surface may possess a Berry curvature. We show that if the Berry curvature has a nonvanishing flux through the Fermi surface, the particle number associated with this Fermi surface has a triangle anomaly in external electromagnetic fields. We show how Landau's Fermi liquid theory should be modified to take into account the Berry curvature. We show that the "chiral magnetic effect" also emerges from the Berry curvature flux.

Rational destabilising speculation and the riding of bubbles

Year: 2003
Subjects: SECS-P/11 Economia degli intermediari finanziari

description: We present a model where it can be optimal for rational informed speculators/arbitragers to ride the bubble instead of using their information for stabilising purposes. This result stems from the interaction of speculators with behavioural traders. These latter in each period of time either discover the true fundamental value of the asset, or use a positive feedback strategy. We study the equilibrium strategy profiles of speculators in the case of short and long horizons and derive the resulting average expected excess deviation of the asset price. Further we consider the possibility of market manipulation and its consequences on the market efficiency.
Quantum Dynamics of a Bose Superfluid Vortex

description: We derive a fully quantum-mechanical equation of motion for a vortex in a 2-dimensional Bose superfluid, in the temperature regime where the normal fluid density $ρ_n(T)$ is small. The coupling between the vortex "zero mode" and the quasiparticles has no term linear in the quasiparticle variables -- the lowest-order coupling is quadratic. We find that as a function of the dimensionless frequency $\tilde Ω= \hbar Ω/k_BT$, the standard Hall-Vinen/Iordanskii equations are valid when $\tilde Ω\ll 1$ (the "classical regime"), but elsewhere, the equations of motion become highly retarded, with significant experimental implications when $\tilde Ω\gtrsim 1$.

description: We present an analysis of sets of matrices with rank less than or equal to a specified number $s$. We provide a simple formula for the normal cone to such sets, and use this to show that these sets are prox-regular at all points with rank exactly equal to $s$. The normal cone formula appears to be new. This allows for easy application of prior results guaranteeing local linear convergence of the fundamental alternating projection algorithm between sets, one of which is a rank constraint set. We apply this to show local linear convergence of another fundamental algorithm, approximate steepest descent. Our results apply not only to linear systems with rank constraints, as has been treated extensively in the literature, but also nonconvex systems with rank constraints.

Astrocytes in psychotic disorder
Creators: name: Feresten, Abigail Helms
Publisher: name: University of British Columbia
Year: 2013

description: Astrocyte dysregulation has been implicated in the pathophysiology of schizophrenia (SCZ) and bipolar disorder (BPD), however the exact nature of astrocytic alterations remains to be identified. I investigated whether levels of four astrocyte-specific proteins; glial fibrillary acidic protein (GFAP), aldehyde dehydrogenase type 1L1 (ALDH1L1), vimentin, and excitatory amino acid transporter type 1 (EAAT1) are altered in SCZ and BPD. Immunohistochemical staining of ALDH1L1 and GFAP in human grey and white matter was also performed, and staining patterns compared qualitatively. Relative concentrations of GFAP, ALDH1L1, vimentin, and EAAT1 were assessed post-mortem in the dorsolateral prefrontal cortex in SCZ (n=35), BPD (n=34) and non-psychiatric control (n=35) groups by western blotting. The same proteins were also quantified in the cingulate cortex of rats administered the antipsychotics haloperidol and clozapine. Elevated levels of GFAP were observed in SCZ and BPD, when compared to controls. GFAP was also significantly increased in individuals with psychotic symptoms, when compared to those without. Vimentin, ALDH1L1 and EAAT1 levels did not differ between groups. Rats exposed to antipsychotics did not exhibit significant overall differences in any astrocytic protein, suggesting that increased GFAP in SCZ is not attributable to antipsychotic treatment. Our findings indicate that astrocyte pathology may be associated with psychotic symptoms. Lack of ALDH1L1 and vimentin variability, paired with increased GFAP levels, may imply that astrocyte numbers are unchanged but astrocytes are partially activated, or may indicate a specific dysregulation of GFAP. Immunohistochemical results suggest that ALDH1L1 may be a more reliable marker of astrocytes than GFAP in human grey matter.

description: We study the interactions between technological innovation, investment in human capital and child labor. In our setting new technologies require new skills and new skills can be developed only through schooling. In a two-stage game, first firms decide on innovation, then households decide on education. In equilibrium the presence of inefficient child labor depends on parameters related to technology, parents’ altruism and the diffusion of firm property. When child labor exists, it is due to either firms reluctance to innovate or households’ unwillingness to educate or both. The optimal policy to eliminate child labor depends crucially on its underlying cause. We show that, in some cases, compulsory schooling laws or a ban on child labor are welfare reducing, while a subsidy to innovation is the right tool to eliminate child labor and increase welfare.

Subjects: SECS-P/01 Economia politica

description: This paper investigates the economic consequences of international migration from the point of view of destination countries. Consistently with international evidence on migration flows, we build a model where the migration rate is higher among the highly-educated. A negative relationship is shown to exist between the domestic wage level and the percentage of educated workers among immigrants, which raises interesting policy implications. In particular, the optimal immigration policy from the point of view of natives requires an immigration quota above a certain minimum level. Extending the analysis to a dynamic setting, we highlight additional effects of the immigration quota on human capital accumulation among natives.

description: We call attention to the intermediate constructions $\T_n F$ in Goodwillie's Calculus of homotopy functors, giving a new model which naturally gives rise to a family of towers filtering the Taylor Tower of a functor. We also establish a surprising equivalence between the homotopy inverse limits of these towers and the homotopy inverse limits of certain cosimplicial resolutions. This equivalence gives a greatly simplified construction for the homotopy inverse limit of the Taylor tower of a functor $F$ under general assumptions.

Subjects: SECS-P/02 Politica economica

description: This paper deals with the aggregate effects of small, exogenous but idiosyncratic technological shocks on locally interacting firms. Its main purpose is to model a situation in which technological paradigms emerge through endogenous propagation and diffusion of information leading to an aggregate pattern. We develop a theoretical framework in which large technological correlations emerge due to localised interaction of single firms. The paper states some simple results on spill-over dynamics determined by firms trying to improve their current technology and thus generating new information through investment in R&D and through localised technological search. The first part shows that different growth regimes can arise from the general framework of interaction that we propose. The second part shows that an interesting regime characterised both by long run innovation growth and endogenous short run fluctuations emerges spontaneously.

description: We present a Scanning Tunneling Microscopy (STM) investigation of gold deposited at the magnetite Fe3O4(001) surface at room temperature. This surface forms a reconstruction with (\surd2\times\surd2)R45° symmetry, where pairs of Fe and neighboring O ions are slightly displaced laterally, forming undulating rows with 'narrow' and 'wide' adsorption sites. At fractional monolayer coverages, single Au adatoms adsorb exclusively at the narrow sites, with no significant sintering up to annealing temperatures of 400 °C. The strong preference for this site is possibly related to charge and orbital ordering within the first subsurface layer of the reconstructed Fe3O4(001) surface. Because of their high thermal stability, the ordered Au atoms at Fe3O4(001)- (\surd2\times\surd2)R45° could provide useful for probing the chemical reactivity of single atomic species.

description: Consider a marketing division of a monopoly firm that faces two marketing options: Market enlargement and elasticity improvement. These options are conceived in terms of the target of the firm’s advertising campaigns: Potential new consumers versus existing consumers. Using a CES demand function in a simple model, we demonstrate that the two activities are complementary, so that for some cost configurations, the firm will find it profitable to implement the two options together when either option alone would result in a loss. This calls for the marketing division to be integrated, rather than decentralized.

description: In the time since a merger of quantum mechanics and game theory was proposed formally in 1999, the two distinct perspectives apparent in this merger of applying quantum mechanics to game theory, referred to henceforth as the theory of "quantized games", and of applying game theory to quantum mechanics, referred to henceforth as "gaming the quantum", have become synonymous under the single ill-defined term "quantum game". Here, these two perspectives are delineated and a game-theoretically proper description of what makes a multi-player, non-cooperative game quantum mechanical, is given. Within the context of this description, finding a Nash equilibrium in a strictly competitive quantum game is shown to be equivalent to finding a solution to a simultaneous best approximation problem in the state space of quantum objects, thus setting up a framework for a game theory inspired study of "equilibrium" behavior of quantum physical systems such as those utilized in quantum information processing and computation.

Creators: name: Dunbar, Robin R.
Publisher: name: Old Dominion University Libraries
Year: 2021

description: This project focuses on mentoring children to help reduce marine debris in their local river by implementing one of ten lessons from an inquiry-based Riverology curriculum to empower youth voice, increase geo-literacy, and spatial thinking. Eighteen participants aged seven and eight, piloted Riverology Lesson 2: What Do I Know or Imagine about the Elizabeth River? that includes six steps: inquire, visualize, draw, share, act, and reflect. The children were asked to make drawings before and after viewing an Elizabeth River Story Map presentation (Dunbar, 2021a). The drawings were then compared to see if the participants included marine debris, stewardship solutions, and a mental map of the river with branches. This study addresses four questions 1.) Why should we teach youth about rivers? 2.) How can creating art and stories serve as a communication tool for students to share their ideas? 3.) How can visualization activities be utilized to connect youth to their local rivers? 4.) What barriers do students face on their journey to act and participate in the public sphere? Scholars, such as Jürgen Habermas (1974), Sibel Ozsoy and Berat Ahi (2014), Tom Cockburn (2019), Lynda Barry (2019), and Millie Kerr (2016) have advocated for a citizen democracy fueled by youth participation in the arts. Some of these efforts have been applied to environmental conservation, but no such inquiry-based effort has been undertaken to address the stewardship of the Elizabeth River in Virginia. The scale of the marine debris issue sometimes creates the impression that local actions are futile, but research shows people using their own expertise and knowledge as stewards is a driver for change (N. Bennett, et al., 2017). To foster river stewards these young participants completed Riverology Lesson 2 and although none of their pre- drawings included marine debris or stewardship actions, 83% of the post- drawings did. In addition, only 11% drew a mental map of the river in their pre- drawings, but 44% did after viewing maps and images. An unexpected finding showed none of the drawings included people and this may relate to youth empowerment issues, the inquiry question wording, or COVID-19 isolation.

description: The debate about the origins of the war remains a vibrant area of historical research. It has been characterised by a number of features. First, from the outset, political concerns shaped the debate, though these preoccupations have become less significant as the war recedes into the past. Second, the debate is international, though with distinct national emphases. This international character owes much to political concerns, but it also reflects how historians work. Third, the debate has contributed to and been shaped by historiographical developments. This article presents these arguments in a narrative of the debate since 1914.

description: We perform a detailed study of the bispectrum of the Sunyaev-Zel'dovich effect. Using an analytical model for the pressure profiles of the intracluster medium, we demonstrate the SZ bispectrum to be a sensitive probe of the amplitude of the matter power spectrum parameter sigma_8. We find that the bispectrum amplitude scales as B_SZ ~ sigma_8^{11-12}, compared to that of the power spectrum, which scales as A_tSZ ~ sigma_8^{7-9}. We show that the SZ bispectrum is principally sourced by massive clusters at redshifts around z~0.4, which have been well-studied observationally. This is in contrast to the SZ power spectrum, which receives a significant contribution from less-well understood low-mass and high-redshift groups and clusters. Therefore, the amplitude of the bispectrum at l~3000 is less sensitive to astrophysical uncertainties than the SZ power spectrum. We show that current high resolution CMB experiments should be able to detect the SZ bispectrum amplitude with high significance, in part due to the low contamination from extra-galactic foregrounds. A combination of the SZ bispectrum and the power spectrum can sharpen the measurements of thermal and kinetic SZ components and help distinguish cosmological and astrophysical information from high-resolution CMB maps.

description: We analyze various possible superconducting pairing states and their relative stabilities in lightly doped graphene. We show that, when inter-sublattice electron-electron attractive interaction dominates and Fermi level is close to Dirac points, the system will favor intra-valley spin-triplet $p+\mathrm{i}p$ pairing state. Based on the novel pairing state, we further propose a scheme for doing topological quantum computation in graphene by engineering local strain fields and external magnetic fields.

description: Electron doping of a 122-type iron pnictide BaFe2As2 by substituting the Ba site with an aliovalent ion (indirect doping), which had been unsuccessful by conventional solid-state synthesis methods, was achieved by a non-equilibrium film growth process. The substitution with La was substantiated by a systematic shrinkage of the c-axis lattice parameter due to the smaller ionic radius of La3+ than that of Ba2+. A negative Hall coefficient indicated that the majority carriers were electrons, as is consistent with this aliovalent ion doping. The La substitution suppressed an antiferromagnetic transition and induced bulk superconductivity at a maximum onset critical temperature (Tc) of 22.4 K. The electronic phase diagram for (Ba1-xLax)Fe2As2 was built, which revealed that the indirect electron doping at the Ba site with La [(Ba1-xLax)Fe2As2] exhibits almost the same Tc - doping level relation as that of the direct electron-doping at the Fe site with Co [Ba(Fe1-xCox)2As2]. This finding clarified that Tc in 122-type compounds is not affected by a crystallographic doping site, which is in sharp contrast to the 1111-type compounds, REFeAsO (RE = rare earth). It is tentatively attributed to the differences in their dimensionality of electronic structures and electron pairing symmetries.

description: Recent efforts to classify representations of supersymmetry with no central charge have focused on supermultiplets that are aptly depicted by Adinkras, wherein every supersymmetry generator transforms each component field into precisely one other component field or its derivative. Herein, we study gauge-quotients of direct sums of Adinkras by a supersymmetric image of another Adinkra and thus solve a puzzle from Ref.[2]: The so-defined supermultiplets do not produce Adinkras but more general types of supermultiplets, each depicted as a connected network of Adinkras. Iterating this gauge-quotient construction then yields an indefinite sequence of ever larger supermultiplets, reminiscent of Weyl's construction that is known to produce all finite-dimensional unitary representations in Lie algebras.

description: A phenomenological theory of the fluctuations of velocity occurring in a fully developed homogeneous and isotropic turbulent flow is presented. The focus is made on the fluctuations of the spatial (Eulerian) and temporal (Lagrangian) velocity increments. The universal nature of the intermittency phenomenon as observed in experimental measurements and numerical simulations is shown to be fully taken into account by the multiscale picture proposed by the multifractal formalism, and its extensions to the dissipative scales and to the Lagrangian framework. The article is devoted to the presentation of these arguments and to their comparisons against empirical data. In particular, explicit predictions of the statistics, such as probability density functions and high order moments, of the velocity gradients and acceleration are derived. In the Eulerian framework, at a given Reynolds number, they are shown to depend on a single parameter function called the singularity spectrum and to a universal constant governing the transition between the inertial and dissipative ranges. The Lagrangian singularity spectrum compares well with its Eulerian counterpart by a transformation based on incompressibility, homogeneity and isotropy and the remaining constant is shown to be difficult to estimate on empirical data. It is finally underlined the limitations of the increment to quantify accurately the singular nature of Lagrangian velocity. This is confirmed using higher order increments unbiased by the presence of linear trends, as they are observed on velocity along a trajectory.

Volatility matters: Taylor rules and capital accumulation

description: The operational performance of a set of simple monetary pol-
icy rules à la Taylor in a model with capital accumulation and nominal and real
rigidities is discussed with a special emphasis on the volatility of output, nominal
rate and inflation rate. Within an enriched modelling framework it is shown that
output targeting plays a more crucial role than what has been assessed in the current
literature for models without capital accumulation. In fact, with a small value of
the output targeting coe¢ cient, monetary authority is not completely successfull in
stabilizing the volatility of output, nominal rate and inflation rate only by acting on
inflation targeting. Moreover, a too strong concerns towards inflation relatively to
output translates into a lower ability to control inflation volatility, together with a
strong policy reaction with respect to an exogenous shock hitting the economy. Im-
pulse response analysis shows that the risk of an excessive concerns towards inflation
might end up in counterproductive results on output, after a positive technological
shock. The model also shows a better internal propagation mechanism than what
has been previously showed. Finally, the results show that it is no longer possible
to miss capital accumulation in modelling monetary policy analyses and calls for
further generalizations of the existing modelling framework.

description: On-line content delivery and vertical alliances between conduit
and content providers are nowadays crucial issues in digital markets. In this paper,
we discuss and compare a push and a pull model for on-line content delivery in the
case of non-zero marginal cost for network transits because of network services for
content delivery (like data caching). Under both models, we show that rationales
for vertical strategic integration between conduit and content providers phase out in
successive monopolies and Bertrand duopolies.
Testing exogeneity in the bivariate probit model: Monte Carlo evidence and an application to health economics

description: Many economic applications involve the modeling of a binary variable
as simultaneously determined with one of its dycotomous regressors. In
this paper we deal with a prominent health economics case study, that of
cesarean section delivery utilization across public and private hospitals.
Estimating the probability of cesarean section in a univariate framework
neglecting the potential endogeneity of the hospital type dummy might
lead to invalid inference. Since little is known about the exact sampling
properties of alternative statistics for testing exogeneity of a dycotomous
regressor in probit models, we conduct an extensive Monte Carlo experiment.
Equipped with the simulation results we apply a comprehensive
battery of tests to an Italian sample of women and find clear evidence
against exogeneity of the hospital type dummy. We speculate on the
economic implications of these results and discuss the misleading interpretation
arising from the adoption of either univariate probit model or
seemingly unrelated bivariate probit model.
Nonequilibrium thermodynamics of interacting tunneling transport: variational grand potential, density-functional formulation, and nature of steady-state forces

description: The standard formulation of tunneling transport rests on an open-boundary modeling. There, conserving approximations to nonequilibrium Green function or quantum-statistical mechanics provide consistent but computational costly approaches; alternatively, use of density-dependent ballistic-transport calculations [e.g., Phys. Rev. B 52, 5335 (1995)], here denoted `DBT', provide computationally efficient (approximate) atomistic characterizations of the electron behavior but has until now lacked a formal justification. This paper presents an exact, variational nonequilibrium thermodynamic theory for fully interacting tunneling and provides a rigorous foundation for frozen-nuclei DBT calculations as a lowest order approximation to an exact nonequilibrium thermodynamics density functional evaluation. The theory starts from the complete electron nonequilibrium quantum statistical mechanics and I identify the operator for the nonequilibrium Gibbs free energy. I demonstrate a minimal property of a functional for the nonequilibrium thermodynamic grand potential which thus uniquely identifies the solution as the exact nonequilibrium density matrix. I also show that a uniqueness-of-density proof from a closely related study [Phys. Rev. B 78, 165109 (2008)] makes it possible to provide a single-particle formulation based on universal electron-density functionals. I illustrate a formal evaluation of the thermodynamics grand potential value which is closely related to the variation in scattering phase shifts and hence to Friedel density oscillations. This paper also discusses the difference between the here-presented exact thermodynamics forces and the often-used electrostatic forces. Finally the paper documents an inherent adiabatic nature of the thermodynamics forces and observes that these are suited for a nonequilibrium implementation of the Born-Oppenheimer approximation.
