description: The notion that flexible exchange rates insulate a country from foreign shocks is well grounded in theory, from the classics (Meade, 1951; Friedman 1953), to the more recent open economy literature (Obstfeld and Rogoff, 2000). We confront it with new evidence from Europe. Specifically, we study how shocks that originate in the euro area spill over to its neighboring countries. We exploit the variation of the exchange rate regime across time and countries to assess whether the regime alters the spillovers: it does not - flexible exchange rates fail to provide insulation against euro area shocks. This result is robust across a number of specifications and holds up once we control for global financial conditions. We show that the workhorse open-economy model can account for the lack of insulation under a float, assuming that central banks respond to headline consumer price inflation. However, it remains puzzling that policy makers are ready to forego stabilization of economic activity to the extent we found in the data.
The cost of uncoupling GB interconnectors

description: The UK left the EU Integrated Electricity Market on 31/12/20 and with it access to Single Day Ahead Coupling that clears local and cross-border trades jointly – interconnectors are implicitly auctioned. The new the Trade and Cooperation Agreement requires a replacement “Multi-region loose volume coupling” to be introduced before April 2022. Until then, interconnector capacity is allocated by an explicit day ahead auction before the EU auction with nomination after the EU results are known. The paper measures the risks posed by taking positions in each market separately and the resulting costs of uncoupling of GB’s interconnector trade. It compares four forecasts of price differences under two sequencing of markets and explicit auction, determining traders’ risk premia for each. The current timing leads to lower mistakes on the direction of flows, although higher profit volatility, arguing to retain the current timing. Competitive traders locking in their positions after the explicit auction (overstating costs as subsequent trading out of unprofitable positions is ignored) limit the total loss of interconnector revenue from uncoupling to €31 million/yr., and the social cost of uncoupling is €28 million/yr., considerably below earlier estimates in the literature.
Bound state in the vector channel of the extended Nambu--Jona-Lasinio model at fixed f_π

description: We show that, as a consequence of fixing f_π= 93 MeV: (1) a bound state pole in the J^P = 1^- scattering amplitude of the ENJL model exists for arbitrarily weak (positive) vector coupling G_2 so long as the constituent quark mass is sufficiently large; (2) there is a bound state for any quark mass when G_2 \geq 0.6/(8 f_π^2); (3) this bound state becomes massless at G_2 = 1/(8 f_π^2) and a tachyon for G_2 exceeding it. We show by way of an example that the model has no trouble fitting the ρmeson mass simultaneously with other observables.

description: Using the continuum model for low energy non-interacting electronic structure of moiré van der Waals heterostructures developed by Bistritzer and MacDonald [1], we study the competition between spin, charge, and superconducting order in twisted bilayer graphene. Surprisingly, we find that for a range of small angles inclusive of the so-called magic angle, this model features robust Fermi pockets that preclude any Mott insulating phase at weak coupling. However, a Fermi surface reconstruction at $θ\gtrsim 1.2^{\circ}$ gives emergent van Hove singularities without any Fermi pockets. Using a hot-spot model for Fermi surface patches around these emergent saddle points, we develop a random-phase approximation from which we obtain a phase diagram very similar to that obtained recently by Isobe, Yuan, and Fu using the parquet renormalization group [2] but with additional insights. For example, our model shows strong nesting around time-reversal symmetric points at a moderate doping of $\sim 2 \times 10^{11} \text{cm}^{-2}$ away from the van Hove singularity. When this nesting dominates, we predict that charge-order enhances singlet superconductivity, while spin-order suppresses superconductivity. Our theory also provides additional possibilities for the case of unnested Fermi surfaces.

description: Enthusiasm for ‘greening the financial system’ is welcome, but a fundamental challenge remains: financial decision makers lack the necessary information. It is not enough to know that climate change is bad. Markets need credible, digestible information on how climate change translates into material risks. To bridge the gap between climate science and real-world financial indicators, we simulate the effect of climate change on sovereign credit ratings for 108 countries, creating the world’s first climate-adjusted sovereign credit rating. Under various warming scenarios, we find evidence of climate-induced sovereign downgrades as early as 2030, increasing in intensity and across more countries over the century. We find strong evidence that stringent climate policy consistent with limiting warming to below 2°C, honouring the Paris Climate Agreement, and following RCP 2.6 could nearly eliminate the effect of climate change on ratings. In contrast, under higher emissions scenarios (i.e., RCP 8.5), 63 sovereigns experience climate-induced downgrades by 2030, with an average reduction of 1.02 notches, rising to 80 sovereigns facing an average downgrade of 2.48 notches by 2100. We calculate the effect of climate-induced sovereign downgrades on the cost of corporate and sovereign debt. Across the sample, climate change could increase the annual interest payments on sovereign debt by US$ 22–33 billion under RCP 2.6, rising to US$ 137–205 billion under RCP 8.5. The additional cost to corporates is US$ 7.2–12.6 billion under RCP 2.6, and US$ 35.8–62.6 billion under RCP 8.5.

description: We present a systematic analysis of ground state properties of a tunneling system coupled to an Ohmic bath. The nonadiabatic effects induced by coupling with tunneling particle , on the ground state properties of phonons are taken into account. For this we have considered both displacement and deformation of phonons via a variational treatment. The symmetry breaking transition , or the delocalization-localization transition of tunneling particle is presented and is compared with earlier known results. We also show that in the critical regime a gap will be opened near the zero momentum in the spectrum of the phonons. The modified phonon spectrum along with the phonon displacement field correlation functions have been calculated. It is shown that in the critical regime the tunneling system stabilizes the lattice against long wavelength fluctuations.

Vulnerable households and fuel poverty: policy targeting efficiency in Australia’s National Electricity Market

Customer Hardship Policy

description: When Australia established its National Electricity Market (NEM) during the 1990s, reforms were focused on maximising economic efficiency. Little thought was given to distributional outcomes. However, by the 2010s sluggish growth in household incomes, sharp rises in electricity prices and material increases in quantities consumed through surging uptake rates of air-conditioning units led to the possibility of (hot climate) fuel poverty. In the NEM’s Queensland region, longstanding customer hardship policy pre-dated the NEM. With the benefit of hindsight, the policy was poorly configured as it focused exclusively on the aged population and was delivered by way of fixed payment. Low income households in the family formation cohort were excluded from the policy despite obvious need. In this article, Queensland’s longstanding customer hardship policy is refined using pre-existing (meanstested) welfare mechanisms in order to target low income households including families, and the payment structure is altered from fixed ($ pa) to variable (% of the bill) while holding the budget constraint constant. Changes to policy targeting produce material improvements in horizontal and vertical efficiency while changes to payment structure further enhance vertical performance, with the incidence and depth of residual fuel poverty reduced.

Creators: name: Klein, Steven Mark
Publisher: name: George Mason University
Year: 1997

description: History is the study of the past in all its splendid messiness, writes the historian Simon Schama. And for a baseball fan, what more splendid mess could there be than the crooked World Series of 1919? F. Scott Fitzgerald, no great baseball fan despite his friendship with Ring Lardner, found the Black Sox scandal to be the perfect metaphor for American disillusionment after World War I. Fitzgerald wrote his great American novel, The Great Gatsby, with its memorable references to the fix, within easy memory of the scandal. Fitzgerald understood that the illegitimacy of the defining event of the Great American Pastime represented the ultimate deception of American popular culture that is so well articulated in the mythology, if not the reality, of baseball. Although most sportswriters of the day had a sense that the 1919 World Series between the heavily favored Chicago White Sox and underdog Cincinnati Reds was not on the square, only one among them had the courage at the time to write it. Hugh S. Fullerton, then 46-years old and considered among the leading baseball writers of his era, wrote the story that Lardner, given his cynicism, and Grantland Rice, in the sweetness of his nature and style, would not and could not write. “The fake world series of 1919 produced some of the worst newspaper reporting that the American press ever has been guilty of, and while all of us who were detailed to cover the show were not fired for missing the greatest sport story in 20 years is something that I have never understood. We were terrible,” wrote columnist Westbrook Pegler from the more convenient perspective of 1932. Yet today, we celebrate Lardner, revere Rice and barely remember Fullerton, who may have been more respected than either in their day.

description: With new high-resolution CO and HI data, we revisited the large-scale interstellar medium (ISM) environment toward the SS 433/W50 system. We find that two interesting molecular cloud (MC) concentrations, G39.315-1.155 and G40.331-4.302, are well aligned along the precession cone of SS 433 within a smaller opening angle of ~7deg. The kinematic features of the two MCs at ~73--84 km/s, as well as those of the corresponding atomic-gas counterparts, are consistent with the kinematic characteristics of SS 433. That is, the receding gas from SS 433 jet is probably responsible for the redshifted feature of G39.315-1.155 near the Galactic plane and the approaching one may power the blueshifted gas of G40.331-4.302 toward the observer. Moreover, the HI emission at VLSR~70--90 km/s displays the morphological resemblance with the radio nebula W50. We suggest that the VLSR=77\pm5 km/s gas is physically associated with SS 433/W50, leading to a near kinematic distance of 4.9\pm0.4 kpc for the system. The observed gas features, which are located outside the current radio boundaries of W50, are probably the fossil record of jet-ISM interactions at ~10^5 years ago. The energetic jets of the unique microquasar have profound effects on its ISM environment, which may facilitate the formation of molecular gas on the timescale of <0.1 Myr for the ram pressure of ~2x10^6 K cm-3.

The Gender Gap in Household Bargaining Power: A Portfolio-Choice Approach
Creators: name: Gu, R.

Publisher: name: Faculty of Economics, University of Cambridge
Year: 2021

description: We quantify how bargaining power is distributed when spouses make financial decisions together. We build a model in which each spouse has a risk preference and must bargain with each other to make asset decisions for the household. By structurally estimating the model with longitudinal data from Australian households, we show that the average household’s asset allocation reflects the husband’s risk preference 44% more than the wife’s. This gap in bargaining power is partially explained by gender differences in income and employment status, but is also due to gender effects. We provide further evidence that links the distribution of bargaining power to views on gender norms in the cross-section.

Untersuchung des Flammenfrontstreckungseffektes auf die laminare und turbulente Verbrennung unter variierten Druck- und Temperaturbedingungen

description: In der Mehrzahl der Verbrennungsanwendungen in der Praxis werden turbulente Flammen verwendet. Ein besseres Verständnis der Vorgänge, die in der turbulenten Verbrennung stattfinden, ist unabdingbare Voraussetzung für die Erhöhung des Wirkungsgrades von Brennern sowie für eine Reduzierung von Schadstoffen. Da die turbulente Brenngeschwindigkeit von der laminaren Brenngeschwindigkeit und der Intensität der Turbulenz abhängt, ist die laminare Brenngeschwindigkeit ein entscheidender Parameter für die Charakterisierung eines Kraftstoffes. Die turbulente Flamme kann unter bestimmten Bedingungen als Ensemble laminarer Flammen betrachtet werden (Flamelets-Ansatz). Demnach muss auch der Einfluss der Streckung, verursacht durch turbulenzen, auf die Flammenausbreitung berücksichtigt werden. Zu diesem Zweck kann die Markstein-Zahl verwendet werden, die die Reaktion einer laminaren Flamme auf die Flammenstreckung quantitativ bestimmt. Die experimentellen Daten der verbrennungstechnischen Parameter - laminare Brenngeschwindigkeit und Markstein-Zahl des konventionellen Brennstoffs (Kerosin Jet A-1) - sind insbesondere bei überatmosphärischen Drücken kaum vorhanden. Die Bestimmung der Parameter für überatmosphärische Bedingungen ist sehr wichtig, da sie nahe an den tatsächlichen Betriebsbedingungen liegen. Die Entwicklung neuer alternativer Brennstoffherstellungsverfahren ist für die Nachhaltigkeit der Energieversorgung von besonderer Bedeutung. Um konventionelle Kraftstoffe wie Kerosin durch so gewonnene alternative Kraftstoffe zu ersetzen, muss man deren Eigenschaften vergleichen, damit man den am besten geeigneten Ersatz ermittelt. Darüber hinaus können erhebliche Unterschiede im Flammenverhalten, die durch unterschiedliche Verbrennungseigenschaften erkannt werden können, zu einer Modifikation der derzeit verwendeten Brennkammer führen. Die Verbrennungseigenschaften (laminare Brenngeschwindigkeit und Markstein-Zahl) von Kerosin Jet A-1 und alternativen Kraftstoffen (GTL- und GTL-Mischungen) werden experimentell untersucht. In Rahmen dieser Arbeit wird der Einfluss von drei entscheidenden Parametern auf die Verbrennungseigenschaften bestimmt: Anfangstemperatur, Anfangsdruck und Gemischzusammensetzung. Die mit der laminaren Flamme ermittelte Markstein-Zahl wird für stationäre Strömungsbedingungen definiert. Es ist jedoch von Interesse zu verstehen, in wie fern eine so definierte Markstein-Zahl zur Erklärung der turbulenten Flammenfrontausbreitung verwendet werden kann. Desweiteren zeigt die Markstein-Zahl eine Abhängigkeit vom Druck. In der vorliegenden Arbeit wird der Einfluss von Druck und turbulenter Intensität auf den Markstein-Zahl-Effekt bei turbulenter Flammenausbreitung experimentell untersucht. Die Abhängigkeit der Effizienzparameter der Markstein-Zahl von den untersuchten Einflussfaktoren wird definiert.

This method gives theoretically consistent and phenomenologically useful results. Perturbation theory is well behaved, and the largest theoretical error in the predictions coming from the uncertainty in the quark mass is eliminated. The results are applied to the determination of $|V_{cb}|$, $|V_{ub}|$, and $λ_1$.

description: We attempt the numerical construction of an effective action in three dimensions for Ising spins which represent the Wilson lines in the four-dimensional SU(3) gauge theory at finite temperature. For each configuration of the gauge theory, each spin is determined by averaging the Wilson lines over a small neighborhood and then projecting the average to +/-1 according to whether the neighborhood is ordered or disordered. The effective Ising action, determined via the lattice Schwinger-Dyson equations, contains even (two-spin) and odd (one- and three-spin) terms with short range. We find that the truncation to Ising degrees of freedom produces an effective action which is discontinuous across the gauge theory's phase transition. This discontinuity may disappear if the effective action is made more elaborate.

description: Pharmaceutical contamination of surface waters across the United States has become an issue of increasing concern and study. These compounds can negatively impact the health of aquatic species and present an exposure risk to other species and humans who interact with contaminated water or use them as a source of drinking water. Pharmaceutical compounds and metabolites can enter streams from multiple sources including leaky sewer pipes, septic tanks, sewer overflow, and wastewater treatment plant effluent. Although human use is undoubtedly the main source of pharmaceutical loading to streams, stream contamination studies often focus on landscape point and non-point sources as it is difficult to geographically define populations affecting contamination in surface waters. This study develops a method to identify and define human populations contributing to environmental water contamination and additionally uses previous sampling efforts to apply this method at three scales: national, regional, and local. The method developed is also used to understand the relationships between population demographics and socioeconomic factors with type and concentration of pharmaceuticals at each scale using Classification and Regression Tree (CART) analysis. Results indicate that at the national scale, income is an important variable in determining presence of a variety of pharmaceutical groups while at the regional scale age and gender variables were most important. Results at the local scale were not able to be generated with the data available. The method presented and subsequent results may be useful in future study efforts to tailor sampling locations and lab efforts to pharmaceuticals of interest based on contributing populations.

description: Many electricity markets use capacity mechanisms to support generation owners. Capacity payments can mitigate imperfections associated with “missing money” in the spot market and solve transitory capacity shortages caused by investment cycles, regulatory changes, or technology shifts. We discuss capacity mechanisms used in different electricity markets around the world. We argue that strategic reserves, if correctly designed, are likely to be more efficient than market-wide capacity mechanisms. This is especially so in electricity markets that rely on substantial amounts of intermittent generation, hydro power, and energy storage whose available capacity varies with circumstances and is difficult to estimate.

description: We determine the magnetic phase diagram for the YBa$_2$Cu$_3$O$_{6+x}$ and La$_{2-x}$Sr$_x$CuO$_4$ systems from various NMR experiments. We discuss the possible interpretation of NMR and neutron scattering experiments in these systems in terms of both the non-linear $σ$-model of nearly localized spins and a nearly antiferromagnetic Fermi liquid description of magnetically coupled quasiparticles. We show for both the 2:1:4 and 1:2:3 systems that bulk properties, such as the spin susceptibiltiy, and probes at the antiferromagnetic wavevector $(π, π)$, such as $^{63}T_1$, the $ ^{63}Cu$ spin relaxation time, both display a crossover at a temperature $T_{cr}$, which increases linearly with decreasing hole concentration, from a non-universal regime to a $z=1$ scaling regime characterized by spin pseudogap behavior. We pursue the consequences of the ansatz that $T_{cr}$ corresponds to a fixed value of the antiferromagnetic correlation length, $ξ$, and show how this enables one to extract the magnitude and temperature dependence of $ξ$ from measurements of $T_1$ alone. We show that like $T_{cr}$, the temperature $T_*$ which marks a crossover at low temperatures from the $z=1$ scaling regime to a quantum disordered regime, exhibits the same dependence on doping for the 2:1:4 and 1:2:3 systems, and so arrive at a unified description of magnetic behavior in the cuprates, in which the determining factor is the planar hole concentration. We apply our quantitative results for YBa$_2$Cu$_3$O$_7$ to the recent neutron scattering experiments of Fong {\em et al}, and show that the spin excitation near $40 meV$ measured by them corresponds to a spin gap excitation, which is overdamped in the normal state, but becomes visible in the superconducting state.

description: This thesis describes Actuarial science and Fuzzy Logic as relatively recent fields of mathematics introducing methods for containing uncertainty and vagueness in the line of business in which it is being used. Whereas actuaries work on the financial risk in (re)insurance of future events, ‘Fuzzicists’ aim at modeling the degree to which such events may occur. In the process of researching and writing, the author conducted a literature search and review of Fuzzy Set Theory with a structural approach to actuarial modeling. Following the recent development and discoveries of fuzzy logic, life insurance actuaries gained ultramodern modeling techniques, replacing the sole use of probabilities that had started to become insufficient. This thesis is slated to span the applications of Fuzzy Mathematics in the actuarial modeling of Life Contingencies.

vaccination

description: Using daily data on vaccinations, disease spread, and measures of social interaction from Google Mobility reports aggregated at the country level for 112 countries, we present estimates of behavioral responses to the global rollout of COVID-19 vaccines. We first estimate correlates of the timing and intensity of the vaccination rollout, finding that countries which vaccinated more of their population earlier strongly tended to be richer, whereas measures of the state of pandemic or its death toll up to the time of the initial vaccine rollout had little predictive ability after controlling for income. Estimates of models of social distancing and disease spread suggest that countries which vaccinated more quickly also experienced decreases in some measures of social distancing, yet also lower incidence of disease, and in these countries policy makers relaxed social distancing measures relative to countries which rolled out vaccinations more slowly

description: This paper introduces an integrated research and design support tool, called Emergent Designer, developed at George Mason University. It is a tool that implements models of various complex systems, including cellular automata and evolutionary algorithms, to represent engineering systems and their related design processes. The system is intended for conducting design experiments in the area of structural design and for the analysis of their results. It implements state-of-the-art representations supporting generation of novel design concepts and efficient mechanisms for their subsequent optimization at the topological and sizing levels. The first part of this paper describes the overall system's architecture and the flow of information among its components. The actual system's implementation is discussed next and illustrated with several screen shots of the system's graphical user interface. Emergent Designer's novel approach to representing steel structural systems in tall buildings is also presented. It is based on the use of generative representations which utilize cellular automata to generate design concepts. Several design experiments are briefly described to demonstrate the feasibility of Emergent Designer in conceptual design as well as of design processes modeled by complex systems.
Supernova Nebular Spectroscopy Suggests a Hybrid Envelope-Stripping Mechanism for Massive Stars

description: When nuclear fuel in the core of a massive star with a zero-age main-sequence mass $M_{\rm ZAMS} \gtrsim 8M_\odot$ is exhausted, the central part of the iron or magnesium core collapses and forms a neutron star or a black hole. At the same time, the material above the collapsing core is rapidly ejected, leading to a stripped-envelope supernova (SESN) explosion if the outer hydrogen envelope of the star was removed before its explosion. The envelope is presumably stripped either via strong stellar winds or due to mass transfer to a companion star in a close binary orbit. It is not clear which process is dominant, and whether different mechanisms are at work for different classes of SESNe; type IIb, Ib, and Ic SNe in order of increasing degree of envelope stripping. In this work, a new analysis of late-time nebular spectra of SESNe is presented, which is more sensitive to differences in the core structure than early-phase spectral analysis. The results show that the progenitors of SNe IIb and Ib are indistinguishable except for the residual amount of hydrogen envelope while the progenitors of SNe Ic are not only deficient in hydrogen and helium, but are also distinctly more massive than SNe IIb and Ib. These findings strongly suggest that more than one mechanism is responsible for the removal of the outer hydrogen envelope and the deeper helium layer, with the former most likely due to binary interaction, and the latter involving a mass-dependent process such as strong stellar winds or episodic pre-explosion mass ejection.

description: Australia’s National Electricity Market operates in one of the world’s longest and stringiest transmission networks. The 2016-2020 investment supercycle, in which 13,000 MW of renewables were committed, is slowly revealing the limits of network hosting capacity for renewable plant. In this article, side-effects arising from the supercycle are analysed. The majority sources of renewable investment failure relate to deteriorating system strength, viz. associated connection lags, remediation and curtailment costs. Although a multi-zonal market, the NEMs locational investment signals remain visibly strong. A change to nodal arrangements may refine dispatch efficiency but the bigger policy problem is rapidly diminishing network hosting capacity for new renewables, imperfect regulation and regulatory lag associated with augmentation. Markets participants seek to move faster than regulatory frameworks allow. Renewable Energy Zones (REZ) are examined through both i). a consumer-funded regulatory model and ii). a renewable generator-funded market model. A ‘super-sized concessional mezzanine’ facility is presented as a critical element of REZ capital funding. It forms the means by which to optimise market-based REZ transmission augmentation and moderate sponsor risks of transient underutilisation.

description: This paper proposes the method of Specification-LASSO in a flexible semi-parametric regression model that allows for the interactive effects between different covariates. Specification-LASSO extends LASSO and Adaptive Group LASSO to achieve both relevant variable selection and model specification. Specification-LASSO also gives preliminary estimates that facilitate the estimation of the regression model. Monte Carlo simulations show that the Specification-LASSO can accurately specify partially linear additive models with interactive regressors. Finally, the proposed methods are applied in an empirical study, which examines the topic proposed by Freyberger et al. (2020), which argues that firms’ sizes may have interactive effects with other security-specific characteristics, which can explain the stocks excess returns together.

What is the effect of weather on household electricity consumption? Empirical evidence from Ireland

smart metering data

description: We explore the links between weather variables and residential electricity consumption using high-resolution smart metering data. While weather factors have been used for grid-level electricity demand estimations, the impact of different weather conditions on individual households has not been fully addressed. The deployment of smart meters enables us to analyse weather effects in different periods of the day using hourly panel datasets, which would previously have been impossible. To conduct the analysis, fixed-effects models are employed on half-hourly electricity consumption data from 3827 Irish household meters. We demonstrate that temperature has robust and relatively flat effects on electricity demand across all periods, whereas rain and sunshine duration show greater potential to affect individual behaviour and daily routines. The models show that the most sensitive periods differ for each weather variable. We also test the responses to weather factors for weekends and workdays. Weather sensitivities vary with the day of the week, which might be caused by different household patterns over the course of the week. The methodology employed in this study could be instructive for improving understanding behavioural response in household energy consumption. By using only weather indicators, this approach can be quicker and simpler than traditional methods —such as surveys or questionnaires — in identifying the periods when households are more responsive.
