Globular clusters host a variety of lower-luminosity (L
X < 1035 erg s−1) X-ray sources, including accreting neutron stars (NSs) and  black holes (BHs), millisecond pulsars (MSPs), cataclysmic variables, and chromospherically active binaries. In this paper, we provide a comprehensive catalog of more than 1100 X-ray sources in 38 Galactic globular clusters (GCs) observed by the Chandra X-ray Observatory’s Chandra/ACIS detector. The targets are selected to complement the MAVERIC survey’s deep radio continuum maps of Galactic GCs. We perform photometry and spectral analysis for each source, determine a best-fit model, and assess the possibility of it being a foreground or background source based on its spectral properties and location in the cluster. We also provide basic assessments of variability. We discuss the distribution of X-ray binaries in GCs and their X-ray luminosity function, and we carefully analyze systems with L
X > 1033 erg s−1. Among these moderately bright systems, we discover a new source in NGC 6539 that may be a candidate accreting stellar-mass BH or a transitional MSP. We show that quiescent NS low-mass X-ray binaries in GCs may spend ∼2% of their lifetimes as transitional MSPs in their active (L
X > 1033 erg s−1) state. Finally, we identify a substantial underabundance of bright (L
X > 1033 erg s−1) intermediate polars in GCs compared to the Galactic field, in contrast with the literature of the past two decades.
Star-forming versus Quiescent Regions in the Galaxy: A Case Study of ISM Properties Based on 18 cm OH and 12CO (1–0) Observations
Authors: Engelke Philip D. , Allen Ronald J. , Busch Michael P.
Published: September 2020

We infer the density of hydrogen nuclei and optical depths associated with molecular gas in front of a star-forming region and in a quiescent region of the Galactic interstellar medium (ISM) using 18 cm OH and archival 3 mm 12CO observations, together with a diffuse cloud model from the literature. The results indicate that the volume densities of hydrogen nuclei are greatest near the star-forming region, intermediate in the CO-bright portions of the quiescent region, and lowest in the CO-dark portions of the quiescent region. Low volume density and low column density appear to be correlated with the presence of CO-dark molecular gas, which is primarily located in the vast space outside of star-forming regions. Molecular gas containing CO may exist in similar quantities both outside of and in the vicinity of star-forming regions; however, the CO emission radiates more efficiently in regions where the ISM is locally compressed, leading to the observational phenomenon of CO-dark and CO-bright molecular gas. We suggest that processes occurring as a natural consequence of star formation such as shock waves and stellar winds lead to compression of the gas into smaller pockets of higher volume density, and such “clumpy” structures will naturally emit more efficiently in CO owing to higher rates of collisional excitation. In this picture, the apparent prominence of CO emission in and near star-forming regions is itself a by-product of the star formation process.
Clinical Characteristics and Prognostic Factors of Visual Outcomes in Childhood Glaucoma
Authors: Tansuebchueasai Natchada , Kiddee Weerawat , Wangsupadilok Boonchai
Published: September 2020

Purpose:

To determine the prognostic factors for poor visual outcomes in childhood glaucoma.

Methods:

The medical records of patients with childhood glaucoma diagnosed at age 4 years or younger who were treated surgically from 2002 to 2019 at Songklanagarind Hospital, Hatyai, Thailand, were retrospectively reviewed. Glaucoma subtypes, clinical characteristics, final visual acuity, and etiology of visual impairment were recorded. The generalized estimating equation for logistic regression analysis was used to determine prognostic factors for final visual acuity of worse than 20/200.

Results:

Forty-five eyes of 31 patients were included (33.3% had primary glaucoma and 66.7% had secondary glaucoma). At the final visit (mean: 6.8 years), 20.5% had good visual acuity (20/50 or better), 15.9% had fair visual acuity (worse than 20/50 to 20/200), and 63.6% had poor visual acuity (worse than 20/200). The major cause of visual impairment (worse than 20/50) was deprivation amblyopia. Prognostic factors for poor final visual acuity (worse than 20/200) were secondary glaucoma, age at diagnosis of younger than 3 months, and interval to surgery of more than 3 months. Eyes with a final visual acuity of better than 20/200 had higher mean intraocular pressure preoperatively that tended to increase postoperatively and every visit afterward compared to the other group.

Conclusions:

Two-thirds of eyes with childhood glaucoma ended up with poor final vision. Early surgery to control intraocular pressure, along with amblyopia treatment, should be considered to prevent poor visual outcome. The prognostic factors for poor visual outcome can contribute to parental advice and planning of patient care.

P
< .001] compared to older infants. The relative risk of developing any type of ROP in infants with BW of less than 1,200 g was 2.41 (95% CI: 1.35 to 4.29;
P
= .003] and developing type 2 or worse ROP was 2.05 (95% CI: 0.99 to 4.25;
P
= .05).

Conclusions:

Infants in Mongolia with heavier BW and older GA who fall outside of current United States screening guidelines of GA of 30 weeks or younger and/or BW of 1,500 g or less developed clinically relevant ROP.

Immediate Sequential Bilateral Vitreoretinal Surgery: Descriptive Case Series and Literature Review
Authors: Rubowitz Alexander H. , Rosenblatt Hadar Naidorf
Published: September 2020

BACKGROUND AND OBJECTIVE:

Bilateral vision-threatening disease necessitating urgent surgery in both eyes is challenging in vitreoretinal disorders, where surgeries are often longer and higher risk than in other ocular disorders. The authors present a case series of patients undergoing immediate sequential bilateral vitreoretinal surgery (ISBVS) on the same day.

PATIENTS AND METHODS:

Retrospective case series and literature review. Main outcome measures were surgical indications, systemic diseases, presenting and final visual acuity, and adverse events or complications during or after surgery.

RESULTS:

During the time period searched, 14 patients underwent ISBVS, without significant adverse events, infections, or complications. Illustrative cases are presented.

CONCLUSION:

The authors recommend considering ISBVS under certain conditions, such as in patients who are unable to undergo local anesthesia surgery, and in those who definitely require urgent or semi-urgent bilateral vitreoretinal surgery requiring a second general anesthesia in the near future if performed separately, especially in cases where the anesthesia is considered high risk.

Published: September 2020

BACKGROUND AND OBJECTIVE:

Non-causal macular holes (MHs) can occur concurrently with rhegmatogenous retinal detachments (RRDs). The visual outcomes and surgical approach for these eyes are variable.

PATIENTS AND METHODS:

This was a multi-institutional, retrospective review of all primary retinal detachment surgeries from January 1, 2015, through December 31, 2015. Pre-, intra-, and postoperative metrics were recorded.

RESULTS:

There were 2,242 eyes that had pars plana vitrectomy for primary RRD, 43 (1.9%) of which had a MH at the time of surgery. The mean postoperative logMAR visual acuity (VA) for the MH cohort was 0.87 ± 0.64 (20/148) and for eyes without a MH was 0.47 ± 0.63 (20/59;
P
< .0001). The single-surgery re-attachment rate for the MH cohort and no MH cohort was 86.1% and 84.9%, respectively (
P
= 1.0000).

CONCLUSIONS:

Patients with noncausal MHs and RRD had significantly worse VA than patients without a MH. Preoperative counseling is imperative in patients with both RRD and MH.

A conservative semi-Lagrangian finite difference WENO scheme based on exponential integrator for one-dimensional scalar nonlinear hyperbolic equations
Authors: Zhang Guoliang , Zheng Shaoqin , Xiong Tao
Published: September 2020

In this paper, we propose a conservative semi-Lagrangian finite difference (SLFD) weighted essentially non-oscillatory (WENO) scheme, based on Runge-Kutta exponential integrator (RKEI) method, to solve one-dimensional scalar nonlinear hyperbolic equations. Conservative semi-Lagrangian schemes, under the finite difference framework, usually are designed only for linear or quasilinear conservative hyperbolic equations. Here we combine a conservative SLFD scheme developed in [21], with a high order RKEI method [7], to design conservative SLFD schemes, which can be applied to nonlinear hyperbolic equations. Our new approach will enjoy several good properties as the scheme for the linear or quasilinear case, such as, conservation, high order and large time steps. The new ingredient is that it can be applied to nonlinear hyperbolic equations, e.g., the Burgers' equation. Numerical tests will be performed to illustrate the effectiveness of our proposed schemes.
Paralyzed by Fear: Rigid and Discrete Pricing Under Demand Uncertainty
Authors: Ilut Cosmin , Valchev Rosen , Vincent Nicolas
Published: September 2020

We propose a new theory of price rigidity based on firms' Knightian uncertainty about their competitive environment. This uncertainty has two key implications. First, firms learn about the shape of their demand function from past observations of quantities sold. This learning gives rise to kinks in the expected profit function at previously observed prices, making those prices both sticky and more likely to reoccur. Second, uncertainty about the relationship between aggregate and industry‐level inflation generates nominal rigidity. We prove the main insights analytically and quantify the effects of our mechanism. Our estimated quantitative model is consistent with a wide range of micro‐level pricing facts that are typically challenging to match jointly. It also implies significantly more persistent monetary non‐neutrality than in standard models, allowing it to generate large real effects from nominal shocks.
Eliminating Uncertainty in Market Access: The Impact of New Bridges in Rural Nicaragua
Authors: Brooks Wyatt , Donovan Kevin
Published: September 2020

We measure the impact of increasing integration between rural villages and outside labor markets. Seasonal flash floods cause exogenous and unpredictable loss of market access. We study the impact of new bridges that eliminate this risk. Identification exploits variation in riverbank characteristics that preclude bridge construction in some villages, despite similar need. We collect detailed annual household surveys over three years, and weekly telephone followups to study contemporaneous effects of flooding. Floods decrease labor market income by 18 percent when no bridge is present. Bridges eliminate this effect. The indirect effects on labor market choice, farm investment, and savings are quantitatively important and consistent with the predictions of a general equilibrium model in which farm investment is risky, and households manage labor market risk and agricultural risk simultaneously. In the calibrated model, the increase in consumption‐equivalent welfare is substantially larger than the increase in income due to the ability to mitigate risk.
EFFECT OF POLYMER/CEMENT RATIO AND CURING REGIME ON POLYMER MODIFIED MORTAR PROPERTIES
Authors: Hatungimana Daniel , Yazıcı Şemsi , Mardani-Aghabaglou Ali
Published: September 2020

Cement is the most consumed building material in the world. However, cement manufacture is responsible for 5–7% of the world CO2 emissions. In this paper, cement was partially replaced by styrene-butadiene rubber (SBR) polymeric latex in order to reduce cement consumption. Besides, effects of SBR addition on the strength and physical properties of plain mortar exposed to three different curing regimes are presented. Three different curing regimes were applied to the 40 × 40 × 160 mm prismatic mortar specimens: (I): Specimens were cured in water until the test age (CW), (II): after demoulding, specimens were immersed in water for 2 days and kept in ambient temperature until the time of the test (2DWA) and (III) involved 2 days of water curing followed by 1 day in an oven at 50°C and subsequentely placing in ambient temperature until the test time (2W1OA). Results showed that combining 2 days of water curing followed by ambient temperature curing (2DWA) along with 3% SBR polymer content showed good performance in terms of compressive strength, water absorption and void content. Moreover, a good performance in terms of flexural strength was observed by combining 2W1OA curing regime with 2% SBR content. However, the detrimental effect of water curing regime (CW) in terms of compressive and flexural strength was also observed with the increase of SBR ratio.
CITIES, ENERGY AND CLIMATE: SEVEN REASONS TO QUESTION THE DENSE HIGH-RISE CITY
Authors: Butters Chris , Cheshmehzangi Ali , Sassi Paola
Published: September 2020

Dense high-rise cities offer some advantages in terms of sustainability but have considerable downsides. Low-dense and medium-rise typologies have been shown to offer good social qualities; their potential energy and carbon advantages have received less attention. As the energy consumption, emissions of cities and heat island effects increase; we question whether dense, high-rise cities offer optimal sustainability. We discuss seven areas where medium density and lower rise typologies offer advantages in terms of energy and climate including: land use/density; microclimate/green space; energy supply; transports; operational energy/carbon; embodied energy/carbon; and resilience.

The aim is to discuss the cumulative importance of these areas in the context of sustainable energy use and climate emissions. These areas are subject to ongoing research and are only discussed briefly, since the overarching synthesis perspective for urban planning is our focus. The picture that emerges when these points are seen together, suggests that medium density and lower rise options—like traditional European typologies—may offer, in addition to social qualities, very significant advantages in terms of energy, carbon and climate emissions.
TAKING THE “LEED” IN INDOOR AIR QUALITY: DOES CERTIFICATION RESULT IN HEALTHIER BUILDINGS?
Authors: Phillips Hannah , Handy Rod , Sleeth Darrah , Thiese Matthew S. , Schaefer Camie , Stubbs James
Published: September 2020

Indoor Air Quality (IAQ) has been an area of growing concern with the increasing knowledge of health hazards associated with contaminants, particularly in high occupancy buildings where residents may be exposed to high levels of nuisance dust and other contaminants. Leadership and Energy in Environmental Design (LEED®) certification, which is awarded to buildings that prioritize sustainability and efficient resource use, has been increasingly sought in new construction. As LEED-certified buildings become more commonplace, it is worthwhile to consider whether these new building practices improve IAQ for its occupants. This study compares particulate matter (PM) concentrations in 12 LEED-certified buildings to 12 analogous non-LEED certified buildings on the University of Utah campus. Real-time air sampling was conducted in each building for PM measurements and a Wilcoxon signed rank test was conducted to compare PM levels. A statistically significant difference was found between LEED certification and PM concentrations, with LEED-certified buildings containing, on average, approximately half the PM of their non-LEED counterparts. These findings suggest that LEED certification is worth the financial investment, as it may lead to improved IAQ for residents. However, further research on other contaminants is warranted, including the characterization and comparison of formaldehyde and carbon dioxide levels.
Temperature Effect on the Modal Frequencies of Aluminum Honeycomb Plate
Authors: Amri Redha
Published: September 2020

The aim of this paper is to perform a study on how the elevated temperature and gradient of temperature affect the natural frequencies of aluminum honeycomb plate. This study is carried out for temperature range between 200K and 800K, and gradient temperature (ΔT) across the thickness direction of the plate between [0-500K]. Different honeycomb plate geometries have been selected for the analysis, by changing the core thickness, skins thickness and cell size. The obtained results show that the effect of the temperature is noticeable. At temperature 800K, the natural frequencies decrease by 16.1% in comparison to their values at ambient temperature (300K). That means, high temperature makes the material suffers from weak rigidity, which furthermore contribute to high decrease of all the frequencies. In addition, investigations carried out in this work relate to the modal analysis of the honeycomb plate, under various gradients of temperature across the core of the plate. The obtained results show that the gradient of temperature has an effect on the modes of vibration of the honeycomb plate. This effect becomes significant when the gradient of temperature is very high. At ΔT equal 500K, the natural vibration modes decrease by 9.5% in comparison to the case where no gradient of temperature (ΔT = 0K) is applied between the two faces of the plate. Keywords: honeycomb panel; aluminum; natural frequency; finite element method; temperature.
Effect on Shear Strength and Hardness Properties of Tin Based Solder Alloy, Sn-50Bi, Sn-50Bi+2%TiO2 Nanoparticles
Authors: Amares Singh , Tchari Bandar
Published: September 2020

Solder alloys are important joining medium widely used in the electronics industry to connect components to printed circuit board PCB. The Sn-Pb solder alloys have been the cornerstone medium used for a long time. Unfortunately, the use of Pb was banned by the European Union due to the harmful environmental and health issues with Pb. Therefore, in this study, the Sn-50Bi and Sn-50Bi+2%TiO2 nanoparticles lead-free solder alloy is investigated based on their shear strength, Vickers hardness, and melting temperature. The investigation shows that the hypo eutectic Sn-50Bi has a low melting temperature of approximately 145°C, and the 2%TiO2 nanoparticles reinforced Sn-50Bi has a melting temperature of around 182°C, which is lower than the traditional Sn-Pb (Tm=183 °C) and Sn-Ag-Cu (Tm=227°C). Furthermore, the developed Sn-50Bi had a Vickers hardness and shear strength of 26.81 HV and 40.78 MPa respectively, higher than the other leaded and lead-free solders. However, after the reinforcement, the hardness increased by 12% (30 HV) and a slight increase of 2.5% (42.4MPa) in shear strength. Overall, the addition of the TiO2 nanoparticles showed a clear influence on the Sn-Bi properties. The results obtained from this study seem satisfactory to the electronic industry and the environment.
Synthesis of Modifiers in the System Cao-Sio2-H2O and their Influence on the Non-Autoclave Silicate Materials’ Properties Using Aluminosilicate Binder
Authors: Volodchenko Aleksandr
Published: September 2020

Improving the hydration hardening building materials’ operational properties is possible due to the stable macro-, micro-and nanostructures’ creation by the cementing material crystalline aggregate directed modification, which can be achieved through the use of various additives acting as crystallization centers. In the course of the studies, the synthesized modifier effect nature represented by the system was revealed CaO-SiO2-H2O (CSH) on the properties of non-autoclave silicate materials using aluminosilicate binder of various compositions. It has been established that the use of an aluminosilicate binder together with the addition of a CSH modifier increases the presence of a crystalline phase at all stages of hardening, as well as intensifies the synthesis of low-basic calcium hydro silicates with a higher crystallization degree in the system CaO-SiO2(Al2O3)-H2O represented by lime and clay rocks. This contributes to the micro-reinforced crystalline framework formation of the neoplasms with increased strength. Due to this, the pore space decreases and the amount of synthesized crystalline substance increases, which helps to increase the water resistance of the samples in all compositions. The samples using an aluminosilicate binder and the addition of a CSH modifier achieve maximum strength with a CaO content of not more than 10 wt. % The optimal CSH modifier addition is up to 1.5 wt. %, with 7 wt. %, CaO content in a mixture increase in strength is up to 6%.

The aim of the research was to study the activation technology of the materials for concrete by their surface modification in a high-voltage electric field. It is noted that the mineral additives modified in a high-voltage electric field are characterized by a higher activity of the calcium hydroxide absorption. It was established that, despite the presence of a large number of crystalline compounds in metakaolin, its pozzolanic activity in the absorption of calcium hydroxide from a saturated solution is quite high. The same value of the hydration activity coefficient is also determined for the ground slag.
The authors found that a characteristic feature of the dispersed mineral additives, surface-modified in a high-voltage electric field in comparison with control samples, are the lower values ​​of bulk density and repose angle. This is due to a change in the forces balance that occurs during the mutual contact of particles. The influence of the mineral additives’ surface modification in a high-voltage electric field on interparticle interactions in the “solid – liquid” system is evaluated. It is established that in the absence of a repulsion barrier, the particles form the aggregates that increase their sedimentation rate. During unipolar or bipolar charging of particles in an electric field, the sedimentation rate slows down or accelerates accordingly. These effects are used to modify the cement surface.

Concretes with frame structure produced by using the technology of separate concreting by immersing a coarse aggregate in a low-viscosity mortar matrix due to an increased concentration of coarse aggregate have an increased E-modulus, reduced creep coefficient and cement volume in concrete compared to traditional vibrational compaction concretes. Production concrete using separate concreting technology by immersing a coarse aggregate in a mortar matrix with low-viscosity allows to obtain a frame structure of concrete with a concentration of coarse aggregate up to 0.7 when a voidness of coarse aggregate is equal 0.28. The real concentration of coarse aggregate in a concrete structure depends on the particle size of the coarse aggregate, the cross-section dimensions of the structure, and the reinforcement coefficient. The influence of geometric dimensions and the coefficient of reinforcement on the concentration of coarse aggregate in the concrete with frame structure is studied. The concentration of coarse aggregate decreases with the growth of the S/V modulus (S – area, m2, V – volume, m3) and the reinforcement coefficient, but the decrease in the E-modulus does not exceed 5%. Conclusion: regardless of the type of construction and reinforcement, the concrete of the frame structure must have a sufficiently high uniformity of deformation properties.

The NLRP3 inflammasome is associated with a variety of human diseases, including cryopyrin-associated periodic syndrome (CAPS). CAPS is a dominantly inherited disease with NLRP3 missense mutations. Currently, most studies on the NLRP3-inflammasome have been performed with mice, but the activation patterns and the signaling pathways of the mouse NLRP3 inflammasome are not always identical with those in humans. The NLRP3 inflammasome activation in pigs is similar to that in humans. Therefore, pigs with precise NLRP3-point mutations may model human CAPS more accurately. In this study, an NLRP3 gain-of-function pig model carrying a homozygous R259W mutation was generated by combining CRISPR/Cpf1-mediated somatic cell genome editing with nuclear transfer. The newborn NLRP3 R259W homozygous piglets showed early mortality, poor growth, and spontaneous systemic inflammation symptoms, including skin lesion, joint inflammation, severe contracture, and inflammation-mediated multiorgan failure. Severe myocardial fibrosis was also observed. The tissues of inflamed skins and several organs showed significantly increased expressions of NLRP3, Caspase-1, and inflammation-associated cytokines and factors (i.e., IL-1β, TNF-α, IL-6, and IL-17). Notably, approximately half of the homozygous piglets grew up to adulthood and even gave birth to offspring. Although the F1 heterozygous piglets showed improved survival rate and normal weight gain, 39.1% (nine out of 23) of the piglets died early and exhibited spontaneous systemic inflammation symptoms. In addition, similar to homozygotes, adult heterozygotes showed increased delayed hypersensitivity response. Thus, the NLRP3 R259W pigs are similar to human CAPS and can serve as an ideal animal model to bridge the gap between rodents and humans.

Lung fibrosis and tissue remodeling are features of chronic diseases such as severe asthma, idiopathic pulmonary fibrosis, and systemic sclerosis. However, fibrosis-targeted therapies are currently limited. We demonstrate in mouse models of allergen- and bleomycin-driven airway inflammation that neutralization of the TNF family cytokine TL1A through Ab blocking or genetic deletion of its receptor DR3 restricted increases in peribronchial smooth muscle mass and accumulation of lung collagen, primary features of remodeling. TL1A was found as a soluble molecule in the airways and expressed on the surface of alveolar macrophages, dendritic cells, innate lymphoid type 2 cells, and subpopulations of lung structural cells. DR3 was found on CD4 T cells, innate lymphoid type 2 cells, macrophages, fibroblasts, and some epithelial cells. Suggesting in part a direct activity on lung structural cells, administration of recombinant TL1A into the naive mouse airways drove remodeling in the absence of other inflammatory stimuli, innate lymphoid cells, and adaptive immunity. Correspondingly, human lung fibroblasts and bronchial epithelial cells were found to express DR3 and responded to TL1A by proliferating and/or producing fibrotic molecules such as collagen and periostin. Reagents that disrupt the interaction of TL1A with DR3 then have the potential to prevent deregulated tissue cell activity in lung diseases that involve fibrosis and remodeling.
Immune Response Resetting as a Novel Strategy to Overcome SARS-CoV-2–Induced Cytokine Storm
Authors: Nowill Alexandre E. , de Campos-Lima Pedro O.
Published: September 2020

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) causes coronavirus disease 2019 (COVID-19), which rapidly became a pandemic of global proportions. Sepsis is commonly present with high lethality in the severe forms of the disease. The virus-induced cytokine storm puts the immune system in overdrive at the expense of the pathogen-specific immune response and is likely to underlie the most advanced COVID-19 clinical features, including sepsis-related multiple organ dysfunction as well as the pathophysiological changes found in the lungs. We review the major therapeutic strategies that have been considered for sepsis and might be amenable to repurposing for COVID-19. We also discuss two different immunization strategies that have the potential to confer antiviral heterologous protection: innate-induced trained immunity and adaptive-induced immune response resetting.
Fourier coefficients of minimal and next-to-minimal automorphic representations of simply-laced groups

Published: September 2020

In this paper, we analyze Fourier coefficients of automorphic forms on a finite cover G of an adelic split simply-laced group. Let
$\pi $
be a minimal or next-to-minimal automorphic representation of G. We prove that any
$\eta \in \pi $
is completely determined by its Whittaker coefficients with respect to (possibly degenerate) characters of the unipotent radical of a fixed Borel subgroup, analogously to the Piatetski-Shapiro–Shalika formula for cusp forms on
$\operatorname {GL}_n$
. We also derive explicit formulas expressing the form, as well as all its maximal parabolic Fourier coefficient, in terms of these Whittaker coefficients. A consequence of our results is the nonexistence of cusp forms in the minimal and next-to-minimal automorphic spectrum. We provide detailed examples for G of type
$D_5$
and
$E_8$
with a view toward applications to scattering amplitudes in string theory.
Fiscal policies in a monetary union: the eurozone case
Authors: Zezza Gennaro
Published: September 2020

We argue that the institutional framework of the eurozone was designed to deny a role for fiscal policy. However, the Great Recession of 2008–2009 forced governments to intervene, mainly to avoid the collapse of their financial systems. At the same time, the severe recession implied a decrease in tax revenues, and an increase in some components of public expenditure – such as unemployment benefits, which implied an increase in public deficits. When the crisis seemed to be over, the Maastricht rules gave priority to restoring fiscal targets, even at the cost of prolonged unemployment and stagnation in countries like Greece and Italy. Using the three-balances approach pioneered by Godley, we argue that such policies require the achievement of an external surplus, or else fiscal austerity will worsen the financial position of the private sector. We show that this is indeed how most eurozone countries moved, and argue that such policies are fragile, and possibly not sustainable in the medium term. We suggest the introduction of fiscal currencies as one way of introducing a degree of freedom in the sustainability of the eurozone.
The ECB's policy under the presidency of Mario Draghi: a curse or a blessing for Europe?
Authors: Bofinger Peter
Published: September 2020

The paper discusses the monetary policy of the European Central Bank (ECB) under the presidency of Mario Draghi. It first shows the serious mistakes made under his predecessor, Jean-Claude Trichet, during which period the ECB destabilized rather than stabilized. Draghi, on the other hand, embarked on a more expansive course immediately after taking office, thereby securing the existence of the euro in a very threatening situation. In 2014, he then identified the deflationary risks for the eurozone at an early stage and successfully countered them with massive bond purchases. The undesirable developments for the financial system and especially the banks predicted by his critics, who are to be found primarily among German economists, have not materialized.
