Published: March 2022

The article is concerned with consideration of the theoretical and methodological aspects of the management of competitiveness of insurance companies. It is specified that insurance activity belongs to the most profitable and risky types of business. Over the past few years, there has been a tendency to reduce the number of insurance companies in the insurance market, which will strengthen the processes of concentration, monopolization and competition between powerful players in the insurance market. Under such conditions, the issue of determining the level of competitiveness management of insurers, as well as their competitive advantages and factors that form a competitive position in the market, acquires special relevance and urgency. The versatility of the concept and the actualization of the study of the competitiveness of insurance companies in the insurance market of Ukraine, along with the significant achievements of Ukrainian scholars in this area, determine the need to apply a comprehensive methodology for assessing these processes. To analyze the state of competition in a certain segment of the market, it is proposed to focus on the concentration coefficients and on the Herfindahl-Hirschman Index. The next stage of the assessment is the study of the factors of influence and their ranking by the weight of the impact on the final result. A characterization of the quantitative, qualitative, matrix and graphic methods that can be used in the course of assessing the competitive position, competitive advantages and competitiveness of the insurance company are carried out. As the final stage, an analysis of the efficiency of the insurer’s competitiveness management process based on the SIX SIGMA concept is proposed. It is concluded that managing the competitiveness of an insurance company is a complex process that is formed under the influence of a number of changing and dynamic factors and components, and also has immense number of manifestation forms. That is why the assessment of the level of competitiveness management of insurance companies should be based both on the use of existing methodologies and on the introduction of innovative approaches to the analysis of the level of competitive advantages of business entities in the insurance market of Ukraine

Published: March 2022

The study focuses on the fact that the negative impact of some changes in the global financial and economic system, of course, is reflected in the choice of diagnostic objects, which is carried out in order to form an effective information system for the adaptation of economic entities to real conditions of functioning. The features of the selection of diagnostic objects, which are determined by the purpose, goals, objectives set in the design or acquisition of a diagnostic system of a particular economic system, are considered. It is noted that with the objects of diagnostics at the micro level, scholars mainly include the potential of the enterprise together with the appropriate subspecies (financial, personnel, production-technical, economic). Based on the study of the approaches of scientists, as well as the author’s own research on the choice of diagnostic objects, it is argued that these include: amalgamation of States, country, region, territorial community (TG) or amalgamated hromada (AH), industry, enterprise. Also, the carried out research reveals and visually demonstrates the hierarchical subordination of objects for diagnosing economic systems. It is determined that the objects of diagnostics presented in the study are interrelated and can affect each other. The article states that methodical and constructive content (choice of methods, procedures, coefficients, format of submission of results, etc.) of the diagnostic system depends on the choice of the object or groups of objects. It is considered that at each of the stages of diagnostics, to a certain extent, the qualitative and quantitative characteristics of the object are taken into account, which decisively affect the production of initial information by the diagnostic system and its application in making managerial decisions. It is proved that depending on the selected object of diagnostics, the diagnostic indicators of both internal and external will differ, and so will be their optimal values. It is noted that the indicators of diagnostics of the relevant object should be correlated with each other in order to obtain relevant information for the effective management of the object of diagnostics and forecasting the possible consequences of its change when changing a particular indicator

Published: March 2022

There are human activities that cause problems and affect other living beings negatively. One of these problems is environmental issues like depletion of resources, challenges with electricity, usage of toxic agents, pollution, and waste because of consumption. These aforementioned environmental problems have started to come to society’s concern with the natural environment; businesses have begun to modify their ways in an attempt to address these. A few developments have been integrated to address such issues. That's why green marketing and concepts emerged. Some businesses have been quick to accept concepts and have integrated concerns into all organizational activities. The changes awaken the business world and consumers regarding the responsibilities towards the environment. Consumers are now sensible to these and result preferably environment-friendly products or services. By this, it indicates that consumers are increasingly concerned and are changing their behavior. That means there is a growing market for sustainable and socially responsible products and services. In return for this behavior of the consumers, companies have started to form their marketing strategies so as to appeal to increasing awareness of this environment-friendliness named green marketing. Enterprises adopt green policies in their organizations and marketing mix, which are pricing, promotion, product, and places - distribution activities. Strategies targeting not only making a profit for the day but also for long-term profitability and environmentally friendly sustainability have started to become agendas of the companies. It holds the view that marketing which is a part of the business, not only has to satisfy customers in particular but also has to take into account the interests of society in general. This study will be conducted in order to determine what specific elements are involved with people’s choosing habits and what components do have an impact and effect on them choosing one rather than the other. It further highlights the consumer perception and awareness of green marketing in food enterprises to see how consumer behaviors are influenced and impacted by these practices. The study discusses the market for food enterprises to be utilized more within consumers that have pro-environmental preferences.

AZINLIK FIKHININ TEMELLENDİRİLMESİ
Authors: SEÇKİNER Mehmet Hicabi
Published: March 2022

İslam dünyasındaki siyasi kargaşa ve ekonomik krizler insanları göçe zorlamıştır. Bunun neticesinde Avrupa gibi kıtalarda Müslümanların nüfusu artmış ve gittikçe de artmaktadır. Bu durum, Müslümanların azınlık halinde yaşadığı ülkelerde azınlık fıkhını gündeme getirmiştir. Zira yabancı ülkelerde Müslümanlar mensup oldukları din ile tabi oldukları ülke kanunları arasında sıkışmış haldedirler. İslam tarihinde uluslararası ilişkiler bağlamında oluşturulan dârülislâm ve dârülharb hukukundan ilham alınarak ihdas edilmeye çalışılan azınlık fıkhının gerekçeleri; İslam’ın insanlığa gönderilmiş son din olması, her çağ ve coğrafyada fıkıh üretebilecek evrensel değerlere sahip bulunması, barış dini olan İslam’ın yaşadığı çevre ile iyi ilişkiler kurması olarak özetlenebilir. Azınlık fıkhının temel referans noktası fıkıh mirasının çağın gerçeklerini dikkate alarak yeniden değerlendirilmesi, nas ve kıyastan sonra ictihadın çalıştırıldığı maslahat ilkesinin temel alınmasıdır.

Bu araştırmada, genellikle akvaryumculukta, sıklıkla da pamuk ve elyaf gibi ürünlerin boyanmasında kullanılan toksik ve kanserojen bir boyar madde olan malahit yeşilinin atık sulardan Siirt/Koçpınar kili kullanılarak uzaklaştırılması incelenmiştir. Çalışmamızın ilk aşamasında adsorbent herhangi bir modifiyeye maruz bırakılmadan (K1) gerekli çalışmalarda kullanılmış, ardından aynı işlemler nitrik asit ile modifiye edilen adsorbent (K2) ile tekrar edilmiştir. Çalışmada başlangıç pH’ının (2.0 – 8.0 aralığı), adsorbent miktarının (0.05 g - 1 g aralığı), derişimin (50 ppm - 150 ppm aralığı), sıcaklığın (298 K - 323 K aralığı) ve temas süresinin (0 dk. - 120 dk. aralığı) etkinliği de araştırılmış ve elde edilen veriler Langmuir, Freundlich, D-R izoterm modellerine uygulanmıştır. Çalışma sonucunda en iyi verim pH 5 başlangıç değeri ile 0.2 g adsorbent kullanılarak yapılan çalışmalarda elde edilmiş ve çalışma neticesinde de K1 adsorbenti için %63.05, K2 adsorbentin de %91.99 giderim sağlanmıştır. İzoterm hesaplamaları sonucunda Freundlich izoterm modeline ait korelasyon katsayısı tüm sıcaklıklarda 0.98’den büyük bulunmuştur. D-R izoterm modeli yardımıyla hesaplanan D-R adsorpsiyon serbest enerjisi ise her iki kil ve tüm sıcaklıklar için 8 kJ/mol değerinden küçük bulunmuştur. Termodinamik hesaplamalar yardımıyla bulunan Gibbs serbest enerji değerlerinin negatif olması, adsorpsiyon işleminin kendiliğinden meydana geldiğini göstermiştir.

This study aims to analyze people's interest in traveling in the era of the Covid-19 pandemic, with a focus on online tourism as an alternative to overcoming concerns about exposure to the virus and the imposition of Large-Scale Social Restrictions and Micro and Community- Scale Social Restrictions. The economic downturn in the midst of the threat of the spread of the pandemic which is not yet known when it will end, is a challenge for the government and society to adjust to the existing conditions. Currently, economic activities are re-opening by implementing health protocols to prevent and control the spread of the virus. It is necessary to restore tourists' trust in the midst of anxiety and the need to travel. This study used a qualitative descriptive research design with a cross sectional approach. Through an analysis of people' s interest in traveling in the era of the Covid-19 pandemic, it was found that the community (local tourists) had quite a high interest in online tourism. This is because the community assesses the urgency of fulfilling tourism needs during the Covid-19 pandemic, of course by paying attention to applicable health protocols. In the future, online tourism needs to be developed and introduced to the wider community, of course, judging by the magnitude of tourist attraction and the importance of restoring Indonesian tourism after the Covid-19 pandemic. Furthermore, further research needs to be carried out whether the development of online tourism based on technology and digital platforms will affect tourist visits directly to recreational areas and the implications for commodity transportation service providers or travel agents.

In this study, the COVID-19 protocol is one of the important factors affecting tourist satisfaction and revisit intention.
MODEL MATEMATIKA UNTUK MENENTUKAN NAMA HARI PADA SIKLUS TUJUH, LIMA DAN TIGAPULUH LIMA HARI PADA KALENDER GREGORIAN DI INDONESIA
Authors: Prabowo Agung , Sukono  , Mamat Mustafa
Published: March 2022

Dalam Kalender Jawa (Anno Javanica) terdapat dua jenis nama hari yaitu hari saptawara dan pancawara. Pancawara merupakan siklus lima hari sekali (Legi, Paing, Pon, Wage dan Kliwon). Saptawara merupakan siklus tujuh hari sekali, seperti siklus mingguan pada Kalender Gregorian (Senin, Selasa, Rabu, Kamis, Jumat, Sabtu dan Minggu). Kalender Gregorian tidak mengenal siklus pancawara. Namun, penggunaan Kalender Gregorian di Indonesia menggabungkan siklus tujuh hari dengan siklus lima hari sehingga terdapat nama hari Senin-Legi, Selasa-Paing dan seterusnya. Hasilnya adalah kombinasi 35 hari yang disebut selapanan. Dengan metode kajian pustaka, akan dibangun model matematika untuk menentukan nama hari saptawara, pancawara dan selapanan untuk tanggal tertentu pada Kalender Gregorian. Selanjutnya, model-model matematika tersebut akan dinamakan model saptawara (empat model), model pancawara dan model selapanan (masing-masing dua model).

Published: March 2022

COVID-19 is a respiratory disease that can cause damage to multiple organs throughout the body. Cardiovascular complications related to COVID-19 mainly include acute myocardial injury, heart failure, acute coronary syndrome, arrhythmia, myocarditis. Among them, myocardial injury is the most common complication in COVID-19 hospitalized patients, and is associated with poor prognosis such as death and arrhythmias. There is a continuous relationship between myocardial injury and the severity of COVID-19. The incidence of myocardial injury is higher in critically ill patients and dead patients, and myocardial injury is more likely to occur in the elderly critically ill patients with comorbidities. Myocardial injury is usually accompanied by more electrocardiogram abnormalities, higher inflammation markers and more obvious echocardiographic abnormalities. According to reports, COVID-19 patients with a history of cardiovascular disease have a higher in-hospital mortality, especially in the elder patients. At present, the mechanism of myocardial injury in COVID-19 is still unclear. There may be direct injury of myocardial cells, systemic inflammatory response, hypoxia, prethrombotic and procoagulant state, myocardial interstitial fibrosis, interferon-mediated immune response and coronary artery plaque instability and other related factors, and angiotensin-converting enzyme-2 receptor may play a key role in the myocardial injury in COVID-19.

The output voltage of a photovoltaic (PV) system relies on temperature and solar irradiance; therefore, the PV system and a load cannot be connected directly. To control the output voltage, a DC-DC boost converter is required. However, regulating this converter is a very complicated problem due to its non-linear time-variant and non-minimum phase circuit. Furthermore, the problem becomes more challenging due to uncertainty about the output voltage of the PV system and variation in the load, which is a non-linear disturbance. In this study, an observer-based backstepping sliding mode control (OBSMC) is proposed to regulate the output voltage of a DC-DC boost converter. The input voltage of the converter can be a DC energy source such as PV-based microgrid systems. An adaptive scheme and sliding mode controller constructed from a dynamic model of the converter is used to design an observer. This observer estimates unmeasured system states such as inductor current, capacitor voltage, uncertainty output voltages of the PV cell, and variation of loads such that the system does not need any sensors. In addition, the backstepping technique has been combined with the SMC to make the controller more stable and robust. In addition, the Lyapunov direct method is employed to ensure the stability of the proposed method. By employing the proposed configuration, the control performance was improved. To verify the effectiveness of the proposed controller, a numerical simulation was conducted. The simulation results show that the proposed method is always able to accurately follow the desired voltage with more robustness, fewer steady-state errors, smaller overshoot, faster recovery time, and faster transient response time. In addition, the proposed method consistently produces the least value of integral absolute error.
COVID−19, Anti-NMDA Receptor Encephalitis and MicroRNA
Authors: Wang Hsiuying
Published: March 2022

The coronavirus disease 2019 (COVID-19) pandemic has had an enormous impact on the world, affecting people’s lifestyle, economy, and livelihood. Recently, with the development of vaccines, the number of infected cases has decreased. Many case reports have revealed that COVID-19 may induce other serious comorbidities such as anti-N-methyl-d-aspartate (anti-NMDA) receptor encephalitis. Anti-NMDA receptor encephalitis is an acute autoimmune disease that occurs more commonly in women than in men. To explore the association between COVID-19 and anti-NMDA receptor encephalitis, the microRNA (miRNA) biomarkers of COVID-19, anti-NMDA receptor encephalitis, and other related diseases from the literature are reviewed; then on the basis of these miRNA biomarkers, the relationship between COVID-19 and anti-NMDA receptor encephalitis is discussed. miRNAs are small non-coding RNAs that play important roles in cell differentiation, development, cell-cycle regulation, and apoptosis. miRNAs have been used as biological biomarkers for many diseases. The results in this study reveal that the relationship between anti-NMDA receptor encephalitis and COVID-19 infection or COVID-19 vaccination cannot be excluded; however, the risk that COVID-19 triggers the anti-NMDA receptor encephalitis is not high.

Published: March 2022

Objectives

The molecular subtype plays an important role in breast cancer, which is the main reference to guide treatment and is closely related to prognosis. The objective of this study was to explore the potential of the non-contrast-enhanced chest CT-based radiomics to predict breast cancer molecular subtypes non-invasively.

Methods

A total of 300 breast cancer patients (153 luminal types and 147 non-luminal types) who underwent routine chest CT examination were included in the study, of which 220 cases belonged to the training set and 80 cases to the time-independent test set. Identification of the molecular subtypes is based on immunohistochemical staining of postoperative tissue samples. The region of interest (ROI) of breast masses was delineated on the continuous slices of CT images. Forty-two models to predict the luminal type of breast cancer were established by the combination of six feature screening methods and seven machine learning classifiers; 5-fold cross-validation (cv) was used for internal validation. Finally, the optimal model was selected for external validation on the independent test set. In addition, we also took advantage of SHapley Additive exPlanations (SHAP) values to make explanations of the machine learning model.

Results

During internal validation, the area under the curve (AUC) values for different models ranged from 0.599 to 0.842, and the accuracy ranged from 0.540 to 0.775. Eventually, the LASSO_SVM combination was selected as the final model, which included 9 radiomics features. The AUC, accuracy, sensitivity, and specificity of the model to distinguish luminal from the non-luminal type were 0.842 [95% CI: 0.728−0.957], 0.773, 0.818, and 0.773 in the training set and 0.757 [95% CI: 0.640–0.866], 0.713, 0.767, and 0.676 in the test set.

Conclusion

The radiomics based on chest CT may provide a new idea for the identification of breast cancer molecular subtypes.
Language as a Window Into the Altered State of Consciousness Elicited by Psychedelic Drugs
Authors: Tagliazucchi Enzo
Published: March 2022

Psychedelics are drugs capable of eliciting profound alterations in the subjective experience of the users, sometimes with long-lasting consequences. Because of this, psychedelic research tends to focus on human subjects, given their capacity to construct detailed narratives about the contents of their consciousness experiences. In spite of its relevance, the interaction between serotonergic psychedelics and language production is comparatively understudied in the recent literature. This review is focused on two aspects of this interaction: how the acute effects of psychedelic drugs impact on speech organization regardless of its semantic content, and how to characterize the subjective effects of psychedelic drugs by analyzing the semantic content of written retrospective reports. We show that the computational characterization of language production is capable of partially predicting the therapeutic outcome of individual experiences, relate the effects elicited by psychedelics with those associated with other altered states of consciousness, draw comparisons between the psychedelic state and the symptomatology of certain psychiatric disorders, and investigate the neurochemical profile and mechanism of action of different psychedelic drugs. We conclude that researchers studying psychedelics can considerably expand the range of their potential scientific conclusions by analyzing brief interviews obtained before, during and after the acute effects. Finally, we list a series of questions and open problems that should be addressed to further consolidate this approach.

Published: March 2022

Periodontitis, an inflammatory disease that affects tooth-supporting tissues, is the result of a polymicrobial infection involving mainly Gram negative anaerobic bacteria. The aim of the present study was to investigate the effects of a phenolic-rich extract of cocoa (Theobroma cacao L.) beans on the pathogenic properties of Porphyromonas gingivalis, which is well-known as a keystone pathogen in the development of periodontitis. The effect of the cocoa extract on P. gingivalis-induced activation of the nuclear factor kappa B (NF-κB) transcription factor in a monocyte model was also assessed. The cocoa extract, whose major phenolic compound was epicatechin, inhibited the growth, hemolytic activity, proteolytic activities, and adherence properties (basement membrane matrix, erythrocytes) of P. gingivalis in a dose-dependent manner. It also protected the barrier function of a keratinocyte model against the deleterious effects mediated by P. gingivalis, and attenuated reactive oxygen species (ROS) production by oral keratinocytes treated with P. gingivalis. Lastly, the cocoa extract showed an anti-inflammatory property by preventing P. gingivalis-induced NF-κB activation in monocytes. In conclusion, this in vitro study highlighted the potential value of an epicatechin-rich extract of cocoa beans for preventing and/or treating periodontal diseases.

In this study the authors investigate the state of European financial culture compared to other regions of the world and the programmes launched / to be launched by different European countries to improve it. They discuss the relationship between general indicators of development and financial culture pointing out that a step-by-step development of financial literacy leads to further growth potential as well as the implementation of best practices learnt from different European countries. All that is highly topical, because the Covid-19 pandemic and ongoing digitisation are new challenges to be faced by the experts dealing with the development of financial literacy. Despite the new challenges, they must call attention to the importance of financial culture. By comparing five European countries it has become clear that complex programmes involving many actors are the most effective; in addition, school subjects involving financial culture should be made mandatory.

Successful training of highly qualified personnel is closely related to the preservation of health, improving the performance of students. The article analyzes the experience of using hygienic, pedagogical organization of the educational process in medical university students, as an indicator of increasing motivation to learn, revealing the subjectivity of students, increasing their stress resistance. The purpose of the work is to study the pedagogical hygienic means of the educational process in higher education, which increase the level of stress resistance of medical university students. The study involved respondents aged 20 years, students of the medical university in the number of 150 people. The diagnostic technique of the resilience test was used, which was adapted by D.A. Leontiev and E.I. Rasskazova on the basis of the Hardiness questionnaire, and such indicators of resilience as engagement, control and risk acceptance are analyzed. In the course of the work, it was found that in the general group, the number of students with high and average indicators of general resilience was 69 %, while 31 % of those who participated in the study had low indicators, respectively. Among them, 64 % of respondents showed high engagement parameters, 70 % control, and 87 % risk acceptance. During the experimental work, the group of students was divided into 2 subgroups of 75 people: control and experimental. The program of the formative experiment was thought out, where various pedagogical hygienic means of the educational process were used. The introduction of new pedagogical hygiene products has increased the level of overall resilience. So, the number of people with high parameters of resilience increased by 20 %, and the number of students with a low level of resilience before the experiment decreased to 11 %. In the experimental group, after the introduction of individualization tools, the overall index of resilience significantly increased from 69 % to 89 % (p < 0,05). In the control group, the increase in the index of resilience did not occur, it remained at the same level — 67 %.

La implementación de políticas macroprudenciales para mitigar el riesgo crediticio se ha utilizado en economías emergentes. De acuerdo con la evidencia, estas políticas podrían afectar otras variables financieras como el crecimiento de la cartera de crédito total bancario, la cartera de crédito de vivienda y el precio de los activos, en particular de la vivienda. En marzo de 2011, se modificó en México la constitución de las estimaciones preventivas de riesgos crediticios al crédito a la vivienda de la banca comercial, con base a las expectativas de pérdida de los créditos de hipoteca en lugar de las pérdidas registradas. En adición, entre 2014 y 2015 se realizaron modificaciones en el requerimiento de liquidez y de capital en vivienda. El objetivo de este estudio consiste en examinar si las herramientas de política macroprudencial afectaron el comportamiento de la cartera de crédito total de vivienda de la banca comercial, así como del índice SHF de precios de vivienda, a consecuencia de los cambios macroprudenciales aplicados referente a vivienda. Mediante la metodología de la presencia de cambios estructurales se encontró que estas políticas macroprudenciales, en la banca comercial, tuvo efectos en el crecimiento del crédito hipotecario y existe un proceso inflacionario en el índice SHF de precios de vivienda.
The Impact of Rapid Adoption of Online Assessment on Students’ Performance and Perceptions: Evidence from a Distance Learning University

One of the most sensitive changes faced by universities due to the COVID-19 crisis was the remote assessment of student learning. This research analysed the case of a massive distance learning university that rapidly changed the final assessment (N=126,653 undergraduate students in 2020) from face-to-face exams to entirely online exams. The research focused on the influence of online assessment on academic performance and students’ perception of the new method. Two data sources were used: the contrast of academic performance indicators (assessment, success and achievement rates, and average marks obtained) between the online examination call and the previous ones with face-to-face examinations; and a questionnaire to a sample of students (n=714) on their perception of the online assessment experience. The results show that all the academic performance indicators in the 28 Bachelor Degrees offered at the university increased when the final assessment method turned to online due to the pandemic crisis; and that a majority of students are more favourable to online assessment methods. The discussion places these findings in a context of rapid change, and concludes by identifying the possible implications of online assessment for student retention, organisational challenges, as well as possible further studies.
The Movement of Pure Hearts as the symbol and the road of maturing for pure love
Authors: Kluz Marek
Published: March 2022

Destructive tendencies inside our civilisation affect the virtue of purity in an unprecedented way. Various arguments are being put forward against living a life in chastity. The life in purity is frequently associated with “rejection” of one’s own freedom. It is also argued that chastity is an element of an bygone era. For this reason the issue of sexual purity becomes currently a challenge – there is a need for a strong opposition against the distortions concerning the virtue of purity. For it is purity that provides for the maturing and deepening of love and prepares best for the bodily and spiritual union of woman and man in matrimony. Thus, it is essential to show the beauty and value of chastity. It has to be noted that the Church faithful to the teachings of Jesus Christ promotes all initiatives which in today’s world present chastity as a positive moral value. One of these initiatives is the Movement of Pure Hearts which through appropriate formation helps young people to fight for the purity of heart and body.
Spanish flu and the “brilliant work” of drs Revoredo, Meira and Monteiro of the São Paulo academy of medicine
Authors: Bertucci Liane Maria
Published: March 2022

The foundation of the São Paulo Academy of Medicine (APM) coincided with the period when the deadly Spanish flu began to spread around the planet. During the epidemic in the city of São Paulo, members of the APM were among the doctors who acted in an attempt to minimize the spread of the disease and the multiplication of the fatal cases of this illness. When the number of victims of the flu fell in the city, Drs Galeno de Revoredo, Rubião Meira and Eduardo Monteiro drafted a report, presented at an APM session, with recommendations to combat the epidemic flu in the interior of the state. This article discusses aspects of this report through its contextualization with debates on the disease and the treatment of victims of the flu in the city of São Paulo.
Helicopter Money and Basic Income, or a Work-Based Society? : A Brief History of Wages, Benefits, Loans and Quantitative Easing
Authors: Vargha Bálint Tamás
Published: March 2022

Following the coronavirus outbreak, and especially before infl ation became a key factor in this period, several crisis management proposals raised the possibility of a universal basic income, which could be backed by the central bank’s money creation. Th e following paper is an essay that seeks to grasp the political economic meaning and implications of the propositions related to helicopter money and basic income. We cannot avoid observing the essence of these proposals, presented fundamentally as a distribution-related issue, in the historical context of value, work and money creation. Helicopter money appears in this light as a new paradigm of extensive growth, which at fi rst glance comes off as a fi nancial innovation, but paradoxically rather bears a relationship with a pre-capitalist conception of value. Moreover, helicopter money is a wage-substitute transfer that does not respond to the social and symbolic void that has replaced work. It appears to be a welfare instrument, while it can only rest on the separation of production and consumption on a global scale. Helicopter money is an extension of quantitative easing by other means, which unveils the motives for money creation. It is an overture to the thought experiments of ‘value without work’ and ‘economy without people’.
Special Difficulties in Forecasting GDP in the Pandemic Situation (2020–2021) : Is there a Keynesian resurgence?
Authors: Magas Antal István
Published: March 2022

Why was it extremely difficult to forecast GDP worldwide, especially in the years of 2020-2021? Mainly because a double shock hit both the aggregate demand and supply sides, and it had substantially changed the known behaviour of key participants. Reactions of households and firms became largely unpredictable. The IMF projections of April 2020 had to be revised sharply. It appears the world economy could recover from the biggest output drop since World War II only with the help of extensive public spending schemes. We ask if one can speak of a new wave of Keynesian policies. How long this present overwhelmingly loose fiscal and monetary stance can last? One cannot tell. There are visible threats, for instance in the inflationary environment.
A fiatal felnőttek és a hitelek (kockázatkerülési csapda)
Authors: Béres Dániel , Huzdik Katalin
Published: March 2022

Tanulmányunkban a 18–25 év közötti korosztály hitelekhez való hozzáállását vizsgáltuk két (2013 és 2020) nem reprezentatív felmérés eredményei alapján. A mintában szereplők száma mindkét esetben meghaladta a 1740 főt. Mindkét kérdőív hat blokkból állt, zárt és nyitott kérdéseket, valamint Likert-skálákat tartalmazott. Az eredmények alapján megállapítható, hogy a fiatal felnőttek hitelekhez való hozzáállása alapvetően negatív, ha tehetik, kerülik a hitelfelvételt. A két felmérés között eltelt időszakban a hitelek szélsőséges elutasítottsága mérséklődött. A megkérdezettek hitelfelvételi gyakorlata (a megvalósított hitelcél) tekintetében a pénzügyi kultúra szempontjából is megfelelő, a jövőbe történő befektetésnek is értékelhető. A jövőre vonatkozó várakozásnak jelentős szerepe van a hiteltermék utólagos értékelésekor. A hitelezés intézményének javuló megítélésében jelentős szerepet játszott a két vizsgált időszak között kibontakozó, újradefiniált fogyasztóbarát hitelezési környezet, valamint a támogatási programok hitelintézeti szektoron keresztül történő megvalósítása. A lakosság kockázatkerülő magatartása csapdahelyzetként jelentkezik hitelezés szempontjából.
A GDP-előrejelzés különös nehézségei a járványhelyzetben (2020–2021) : Van-e keynesiánusi újhullám?
Authors: Magas Antal István
Published: March 2022

A cikk tisztázni kívánja, hogy miért volt különösen nehéz a Covid–19-járvánnyal összefüggő outputvesztés mélységét és a visszaesés hosszát előre jelezni 2020–2021-ben. A kettős sokkhatás alapvetően változtatta meg az aggregált keresleti és a kínálati oldal legfőbb szereplőinek magatartását, és a „járványreakció” nehezen volt előre látható. A Nemzetközi Valutaalap (IMF) 2020. áprilisi GDP-becslései komoly korrekciókra szorultak. A világgazdaság a II. világháború utáni időszak legmélyebb visszaeséséből csak a kiterjedt fiskális élénkítések sorozatával tudott visszakapaszkodni a Covid–19 előtti szintjére. Ám a tartósnak ígérkező fiskális programok nyomán beszélhetünk-e az állami szerepvállalás keynesi ihletésű, újhullámáról? Az „ultralaza” fiskális és monetáris politikák veszélyei bizony már látszanak, például az inflációs környezetben.
