Few data sources provide information on private transfers between generations and gender. We use a novel approach based on the National Transfer Accounts methodology to estimate the value of intra-family transfers between generations by age, gender and parental status in Austria 2015. The paper considers monetary transfers together with transfers o...

This study analyses age-specific differences in income trends in nine European countries. Based on data from National Accounts and the European Union Statistics on Income and Living Conditions, we quantify age-specific changes in income between 2008 and 2017 and decompose these changes into employment, wages, and public transfer components. Results...

Objectives Test the behavior of the case fatality rate in a mixed population of vaccinated and unvaccinated individuals by illustrating the role of both the effectiveness of vaccines in preventing deaths and the detection of infections among both the vaccinated (breakthrough infections) and unvaccinated individuals. Methods We simulate three hypot...

New estimates of economic flows by age combined with population projections show that in the coming decades (1) global GDP growth could be slower by about 1 percentage point per year, declining more sharply than population growth; (2) GDP will shift toward sub‐Saharan Africa more than population trends suggest; (3) living standards of working‐age a...

Most nations have responded to the COVID-19 pandemic by locking down parts of their economies starting in early 2020 to reduce the infectious spread. The optimal timing of the beginning and end of the lockdown, together with its intensity, is determined by the tradeoff between economic losses and improved health outcomes. These choices can be model...

One of the principal ways nations are responding to the COVID-19 pandemic is by locking down portions of their economies to reduce infectious spread. This is expensive in terms of lost jobs, lost economic productivity, and lost freedoms. So it is of interest to ask: What is the optimal intensity with which to lockdown, and how should that intensity...

The number of COVID-19 infections is key for accurately monitoring the pandemics. However, due to differential testing policies, asymptomatic individuals and limited large-scale testing availability, it is challenging to detect all cases. Seroprevalence studies aim to address this gap by retrospectively assessing the number of infections, but they...

Nations struggled to decide when and how to end COVID-19 inspired lockdowns, with sharply divergent views between those arguing for a resumption of economic activity and those arguing for continuing the lockdown in some form. We examine the choice between continuing or ending a full lockdown within a simple optimal control model that encompasses bo...

We set up a lifecycle model of a retired scholar who chooses optimally the time devoted to different activities including physical activity, continued work and social engagement. While time spent in physical activity increases life expectancy, continued scientific publications increases the knowledge stock. We show the optimal trade off between the...

In this work, we assess the global impact of COVID-19 showing how demographic factors, testing policies and herd immunity are key for saving lives. We extend a standard epidemiological SEIR model in order to: (a) identify the role of demographics (population size and population age distribution) on COVID-19 fatality rates; (b) quantify the maximum...

We propose a general analytical framework to model the redistributive features of alternative pension systems when individuals face ex ante differences in mortality. Differences in life expectancy between high and low socioeconomic groups are often large and have widened recently in many countries. Such longevity gaps affect the actuarial fairness...

We investigate the impact of a reduction in the pension replacement rate on the schooling choice and on inequality in an overlapping generations model in which individuals differ by their life expectancy and in their cost of attending schooling. Within our framework we illustrate that many pension systems are ex ante regressive due to the differenc...

We provide a broad overview of population changes in Central and Eastern Europe during the last three decades. We review the transformation towards lower and later fertility and smaller family size, recent improvements in mortality and high rates of outmigration to richer regions in Europe. Trends in fertility, mortality and migration since the 199...

Flooding events can affect businesses close to rivers, lakes or coasts. This paper provides an economic partial equilibrium model, which helps to understand the optimal location choice for a firm in flood risk areas and its investment strategies. How often, when and how much are firms willing to invest in flood risk protection measures? We apply Im...

We evaluate the sustainability of the public transfer systems in 24 EU countries using a new cohort-specific indicator, the Human Capital Investment Gap (HKIG). The indicator measures for a certain cohort the difference between the public benefits in old age and the public contributions of the child generation. Calculating the HKIG for the cohort b...

This book highlights the independent causal effects by which human capital accumulation has the potential to affect economic growth. It explains how fertility choices, education investments, and health investments determine the human capital stock, and examines human capital decisions and their relations with wage inequality, the environment and re...

We analyze the optimal life-cycle education decision of a single atomistic individual and show that the standard result of part-time education and part-time work throughout the life-cycle holds only under very special and unrealistic assumptions. Once these assumptions are relaxed, different education strategies become optimal. These range from swi...

This article builds on time use data to explore cross-country differences between Austria, Italy and Slovenia in unpaid labour and its implications in terms of gender distribution of total work. A contribution of this paper is to measure the ‘rush hour of life’ (RHOL) based on age spans in which individuals’ working time (including paid and unpaid...

We explain the simultaneous presence of i) increasing per capita output, ii) declining real wages of low-skilled workers, and iii) a rising wage premium of higher education within a model of economic growth in the age of automation. The theoretical implications are consistent with the data for the United States since the 1970s. Thus, automation con...

Significance Global environmental change and discussions about the drivers of international migration lead to renewed interest in population growth and global demographic change. The notion of the demographic dividend was introduced to highlight the benefits of fertility decline, yet, among African leaders, it is also often interpreted as describin...

By combining an economic two-sector general equilibrium model with a material flow model we study the coupled human-resource-environment feedbacks associated with phosphorus use and recycling, and the economic and environmental effects of implementing phosphorus recovering technologies from waste water. Using recycled phosphorus as fertilizer incre...

Understanding the relationship between drought and population dynamics is increasingly important, particularly in areas where high population growth corresponds with increasing drought risk due to climate change. We examine the relationship between drought events and population dynamics using a stylized hydrology-demography model that has been cali...

In this article, we investigate the effect of demography on wealth inequality. We propose an economic growth model with overlapping generations in which individuals are altruistic towards their children and differ with respect to the age of their parent. We denote the age gap between the parent and their child as generational gap. The introduction...

In general, the spreading of gender egalitarianism has often been associated with a decline in fertility. However, recently a rebound in fertility has been observed in several industrialized countries. A possible explanation of this trend may be the spread of egalitarian values that induced institutional changes - such as expansion of child care fa...

We investigate the differential impact that pension systems have on the labor supply and the accumulation of physical and human capital for individuals that differ by their learning ability and levels of life expectancy. Using a general equilibrium model populated by overlapping generations, in which all population groups interact through the pensi...

In this paper we compare several types of economic dependency ratios for a selection of European countries. These dependency ratios take into account not only the demographic structure of the population, but also the differences in age-specific economic behaviour such as labour market activity, income and consumption as well as age-specific public...

Background: Uninformed generalizations about how many elderly people have ever lived, based on a poor understanding of demography, are found in a surprising number of important publications. Objective: We extend the methodology applied to the controversial question “how many people have ever been born?” initiated by Fucks, Winkler, and Keyfitz, to t...

Background: Between 2000 and 2010, the labor force participation (LFP) of European men stayed mostly constant, whereas the participation of women continued to increase. Participation rates of people close to normal retirement ages rose almost universally. At the same time, the education composition shifted toward higher levels of educational attain...

Interdisciplinary research and education programmes in water science are intended to produce groundbreaking research, often with an emphasis on societal relevance, and prepare future water resource experts to work across disciplines. This paper explores the emerging outcomes from an ongoing doctoral programme currently in its seventh year. Within t...

Individual demographic behaviour cannot be understood in isolation from the social network one is linked to. However, formal models of demographic behaviour lag behind the empirical evidence. In this chapter we demonstrate how agent-based models can be applied to investigate the role of social interactions to explain macro-level demographic pattern...

According to prior studies, female researchers in Austria exhibit a very high level of childlessness and, consequentially, a low mean number of children. Following up on these studies, we analyse childlessness intentions of young female researchers and compare them to those of other highly educated women in other occupations. We examine factors tha...

This paper presents an analysis of the differential role of mortality for the optimal schooling and retirement age when the accumulation of human capital follows the so-called “Ben–Porath mechanism”. We set up a life-cycle model of consumption and labor supply at the extensive margin that allows for endogenous human capital formation. This paper ma...

As many European countries have to cope with a shrinking and aging labor force, one important goal of redistributing work is to increase female labor force participation. In some countries, however, this increase could come at the cost of a reduced fertility rate as childcare facilities might be rare or institutional settings and social support are...

Recently socio-hydrology models have been proposed to analyze the interplay of community risk-coping culture, flooding damage and economic growth. These models descriptively explain the feedbacks between socio-economic development and natural disasters such as floods. Complementary to these descriptive models, we develop a dynamic optimization mode...

With population growth, increasing water demands and climate change the need to understand the current and future pathways to water security is becoming more pressing. To contribute to addressing this challenge, we examine the link between water stress and society through socio-hydrological modeling. We conceptualize the interactions between an agr...

This article introduces a social planner version of a central microfounded New Economic Geography model for explicitly answering whether the symmetric equilibrium of the decentralized market economy is socially desirable. We find that savings incentives are too weak, resulting in an inefficiently low capital stock and therefore an inadequate number...

We examine within a life-cycle set-up the simultaneous choice of health care and retirement (together with consumption), when health care contributes to both a reduction in mortality and in morbidity. Health tends to impact on retire-ment via morbidity, determining the disutility of work, and through longevity, determining the need to accumulate re...

We compare selected European countries using an economic dependency ratio which emphasizes the role of age-specific levels of production and consumption. Our analysis reveals large differences in the age- and gender-specific level and type of production activities across selected European countries and identifies possible strategies to adjust age-s...

Longer lives and fertility far below the replacement level of 2.1 births per woman are leading to rapid population aging in many countries. Many observers are concerned that aging will adversely affect public finances and standards of living. Analysis of newly available National Transfer Accounts data for 40 countries shows that fertility well abov...

The probably biggest challenge for climate change mitigation is to find a secure low-carbon energy supply, which especially is difficult as the supply of renewable sources underlies strong volatility and storage possibilities are limited. We therefore consider the energy sector of a small country that optimizes a portfolio consisting of fossil and/...
