Optimal Consumption and Portfolio Choice: The Impact of Health and Health Risk

This paper investigates the effect of health and health risk on households’ optimal consumption and portfolio allocations over the life cycle. The simulation results show that consumption, savings in bonds, and savings in stocks all increase in health. Compared with poor health households, the healthy households consume 49% higher, invest 27% and 39% more in bonds and in stocks, respectively. The risky portfolio share, which is the ratio of stocks to the total financial assets is positively related with health for most of the lifetime. Regarding the age profile, it demonstrates the same tendency for both health levels: at the very young age, the risky portfolio share is relatively high. Starting from the middle age, this share falls significantly and keeps steady until the end of life. These results emphasize the importance of health and its associated risk in consumption and portfolio decisions. With all other things equal, households’ consumption and investment behaviors are heterogenous across health. It also provides significant policy applications: by promoting health and reducing health risk, it would largely improve households’ well-being: higher consumption, and more savings in financial assets.

Personality Traits Across the Life Cycle: Disentangling Age, Period, and Cohort Effects

Economists increasingly recognise the importance of personality traits for socio-economic outcomes, but little is known about the stability of these traits over the life cycle. Existing empirical contributions typically focus on age patterns and disregard cohort and period influences. This paper contributes novel evidence for the separability of age, period, and cohort effects for a broad range of personality traits based on systematic specification tests for disentangling age, period and cohort influences. Our estimates document that for different cohorts, the evolution of personality traits across the life cycle follows a stable, though non-constant, age profile, while there are sizeable differences across time periods.

A change is (not) gonna come: a 20-year overview of Italian grandparent–grandchild exchanges

Levels of coresidence, residential proximity, face-to-face contacts and intergenerational support exchanges remain overall high and stable across European countries. However, to date, few studies have focused on trends in grandparent–grandchild relations. Therefore, this study aims to investigate whether and to what extent grandparent–grandchild exchanges have changed over time. We used data from the Italian Family and Social Subjects (FSS) Surveys, covering the years 1998–2016, and considered three different currencies of exchanges between grandparents and their grandchildren (coresidence, face-to-face contacts, and grandchild care provision). Our results showed stability over time in coresidence, a small reduction in daily contacts (from 47% in 1998 to 39% in 2016) and an increase in grandchildren care (from 78% in 1998 to 82% in 2016). In addition, we found little changes in the associations between such indicators of intergenerational exchanges and the demographic and socio-economic determinants usually used to explain them. Despite changes among Italian grandparents such as increases in their age profile, in education, and in marital disruption, the relations between grandparents and their grandchildren have so far remained stable over time, with generally high levels of intergenerational exchanges.

The Impact on Ambulance Mobilisations of an Increasing Age Profile of Telecare Service Users Receiving Advanced Proactive, Personalised Telecare in Spain—a Longitudinal Study 2014–2018

Advanced proactive personalised telecare services in Spain have helped service users to live independently in their own homes for longer. Concern was however noted regarding potential impacts on ambulance mobilisations as time in the service, and mean age at cessation, increased. The purpose of this study was to investigate these impacts.A longitudinal study of a telecare service user population in Spain (n = 202.1 k to 247.9 k) was undertaken using anonymised operational data collected in the delivery of proactive and personalised telecare services over the period 2014–2018.For the studied population, ambulance mobilisation on a per-person/per-annum (pp/pa) basis reduced despite the increasing age profile at cessation and with the characteristics of the population at registration remaining otherwise similar over the period. The study identified the positive correlation coefficient between ambulance mobilisations and service user’s dependency levels, and marginal negative correlation in older age bands.In conclusion, the increasing age at cessation has not correlated with an increased proportion of higher dependency service users. Indeed, the share of those over 85 years in the high dependency level decreased. This indicates that the changes in the telecare service which appear to have contributed to increased time living independently may also have helped ensure those continuing to live independently remain in lower risk bands.

Assessment of the COVID-19 epidemiological situation in St. Petersburg

Aim. Identification of epidemiological patterns of the SARS-CoV-2 spread among the population of St. Petersburg during the one-year COVID-19 pandemic period.Materials and methods. The performed analysis focused on the dynamics of COVID-19 cases in St. Petersburg from 2/3/2020 to 4/4/2021 and on the gender-age profile of patients. The information about patients (age, gender, type of the disease, hospitalization, social, and occupational status) was obtained from the database containing the materials from statistical data form No. 058/u.Results. After one year, the dynamics of reported cases of COVID-19 in St. Petersburg shows two cycles of seasonal surge (spring and autumn-winter) and 8 epidemic periods. It has been found that there are no gender-age differences among COVID-19 patients, which can be seen from the relatively similar number of cases among men and women per 100,000 people in each age group during specific epidemic periods. The strong association between clinical manifestations of COVID-19 and the patients' age was detected: Severe cases were more frequently diagnosed in patients over 70 years, regardless of their gender identity. Based on the social and occupational status, the people who were most exposed to the COVID-19 epidemic process were retirees and people whose occupation was associated with health and safety of St. Petersburg. Among the COVID-19 patients, retirees accounted for 13.69% (men) and 17.67% (women). The proportion of healthcare workers was 3.67% (men) and 9.41% (women).Conclusion. It has been assumed that COVID-19 tends to be a seasonal disease featuring annual autumn-winter epidemic cycles. The study addressed prospects of preventive vaccination against COVID-19 in Russia and the importance of tracking the complications pathogenetically associated with the acute phase of the disease in the system of epidemiological surveillance.

Meso-Cenozoic Exhumation of the Linqing Sub-Basin, Bohai Bay Basin: Implications for Cratonic Destruction

The relationship between the tectonic event of the Linqing Sub-basin and the destruction of the North China Craton (NCC) is an important factor to consider when studying geodynamic mechanisms in eastern China. In the current study, we present a low-temperature apatite thermochronological analysis of 14 samples to study the tectonic event of the Linqing Sub-basin. Our data showed that the apatite fission track (AFT) ages were in the range of 53.5–124.4 Ma, and the average track lengths were 8.00–11.24 μm. The grain ages showed that 10 samples had mixed ages and were characterized by discordant distribution. The minimum ages decomposed from AFT ages mainly ranged from 105.3 to 40.8 Ma. We identified a break-in-slope from the depth-minimum age profile, which was related to the Meso-Cenozoic tectonic event. The AFT age data could be decomposed into three age groups, namely, P3 (394.8–215.7 Ma), P2 (124.6–83.4 Ma), and P1 (70.7–40.8 Ma), indicating three significant tectonic events in the NCC. P3 is related to the uplift of the NCC at 445.0–315.0 Ma and deformation and magmatism at 320.0–200.0 Ma. P2 corresponds to the Mesozoic tectonic activities, such as the closure of the Mongol–Okhotsk Ocean, the turning of the Izanagi plate and mantle convection. P1 mainly corresponds to the Izanagi–Pacific ridge, the closure of the Tethys Ocean, and the rotation of the Philippine Sea plate in the Cenozoic. Our study provides evidence for the destruction of the NCC, and has significance for the understanding of the deep mechanism.

Image of deputies of regional parliaments in popular social networks: equality in the era of digitalization

The article examines popular social networks from the standpoint of the gender specificity of the authors and the age profile of users with the aim of further qualitative consideration of the accounts of deputies the analysis of the accounts of the deputies of regional parliaments from a visual and linguistic discursive point of view in the era of the global trend for digitalization is carried out. In the course of the study, the main and gender features of the effective filling of accounts of social networks VKontakte, Instagram, Twitter, Facebook, YouTube, TikTok and Telegram are identified. The empirical basis for the study of the network image was the text and visual content of accounts, as well as threads of comments and user discussions in the accounts of the following regional deputies for the period September 2020 - February 2021. The analysis focuses on the gender specificity of the content of the studied accounts and the reaction of subscribers of both genders to various popular topics in the posts of MPs. For each of the selected social networks, the formed network image of the deputies is analyzed. Also, the article analyzes the gender specificity in the legislative bodies of power among the deputies of regional parliaments, fixes the tendencies of an increase in the number of women in power structures at the regional level. On the basis of the study, conclusions are drawn about the unequal ratio of the representation of women and men in legislative bodies, in contrast to foreign power structures. Gender specificity in the filling of accounts is noted: creation of the image of a “strong woman-deputy”; adherence to personal "family values" in the posts of male deputies. At the end of the article, the main conclusion is given about the low level of efficiency of communications of deputies in the Internet space on the most popular social platforms; recommendations are proposed for changing the indicators of the activity of deputies in social networks at the level of government and each individual deputy.

Unravelling the Taphonomic Stories of Bird Bones from the Middle Pleistocene Layer VIII of Grotte Vaufrey, France

In recent years, several studies have significantly changed our knowledge concerning the use of birds by Neanderthals. However, what remains to be clarified is the geographical and chronological variability of this human behaviour. The present case study provides new information on this topic/debate. The Grotte Vaufrey was discovered during the 1930s and was excavated during different periods. Work carried out by J.-P. Rigaud during the 1980s motivated many multidisciplinary studies in the cave, but accurate studies were not focused on avian remains. In this work, we provide new data on the bird remains from layer VIII (MIS 7), which is the richest among all the sequences and which has an important Mousterian component. Corvids are predominant in the assemblage and are associated with medium-sized birds and small Passeriformes, among others. Most of the remains present modern fractures, which hinder taphonomic interpretation. However, some alterations associated with raptor or mammalian carnivore activities, together with the anatomical representation and age profile, suggest a non-human accumulation of the majority of the bird remains, especially in the case of corvids that naturally died in the cave. However, at least some bones show evidence of anthropic activity, suggesting the occasional use of large- and medium-sized birds by human populations.
