Data & Publications


Most of my research is related to National Transfer Accounts (NTAs), an accounting framework that provides comprehensive and detailed information on the age-patterns of production, consumption and saving, and on public and private transfers between age groups.

Austrian NTAs: Austrian NTAs include information on income, transfers, consumption and saving by age and gender. Included in Austrian NTAs are also production, transfers and consumption through services that are produced by unpaid work. The Austrian NTA data for 2015 and a detailed description is available at: Hammer (2020), National Transfer Accounts for Austria 2015,

Global NTAs: The development of NTAs is coordinated within the global NTA network, a global research network with teams from more than 50 countires. The web page of the NTA network provides detailed information on NTAs. Data data for about 50 countries around the world can be accessed via the database of the NTA project.

European NTAs: Gender-specific NTA datasets for 25 European countries and base year 2010 have been constructed as part of the AGENTA research project. The European NTAs are based on publicly available and harmonised data from Eurostat and can be accessed using the AGENTA data explorer.

The broken generational contract. The concept of an generational contract describes the relation between the intergenerational transfers to the child generation and the transfers
to the elderly population. This relation is out of balance in all European countries: (too) little investments in children, (too) high transfers to the elderly population.

Sustainability of the public transfer system. The Human Capital Investment Gap contrasts the public net benefits that are expected by the members of a certain cohort in old age with the projected public transfers that are made by the children of this cohort.

The rush hour of life. Between age 25 and 45 people face the highest work burden, when unpaid work for children is added to high levels of paid work. However, the total level of work differs considerably between genders, across countries and between different work arrangements.

Subjective cost of children. How does the birth of a child affect the subjective wellbeing of the parents? Although the reduced labour income is compensated by public transfers in most countries, additional child-related expenditure temporarily reduces the perceived economic wellbeing of parents.

Quantifying economic dependency. The demographic dependency ratio measures old and young persons relative to the working age population, interpreting both old and young as “dependent”. We use alternative measures that are based on economic characteristics and better reflect actual economic dependency.
