This paper presents long term projections of the German pension system that are based on a general equilibrium model with overlapping generations (OLG). This framework takes into account the two way feedback of both micro and macroeconomic relationships, meaning that households, for example,...

This paper shows that demographic change plays an important role in the formation of a country's net foreign asset position. An ageing population both lowers the demand and increases the supply of capital in an economy. Fewer workers reduce the required capital stock. As a longer life span leads...

Although information and communication technologies (ICT) consume energy themselves, they are considered to have the potential to reduce overall energy intensity within economic sectors. While previous empirical evidence is based on aggregated data, this is the first large-scale empirical study...

Artificial Intelligence (AI) represents a set of techniques that enable new ways of innovation and allows firms to offer new features of products and services, to improve production, marketing and administration processes, and to introduce new business models. This paper analyses the extent to...

This paper shows that 19th-century industrialization is an important determinant of the significant changes in Germany’s economic geography observed in recent decades. Using novel data on economic activity in 163 labor market regions in West Germany, we establish that nearly half of them...

We apply the boosting estimation method to investigate to what ex-tent and at what horizons macroeconomic time series have nonlinearpredictability coming from their own history. Our results indicate thatthe U.S. macroeconomic time series have more exploitable nonlinearpredictability than...

While recurring and regular variations of weather conditions are implicitly addressed by standard seasonal adjustment procedures of economic time series, extraordinary weather outcomes are not. We propose a way of measuring aggregate abnormal weather conditions based on available local...

The currently observed demographic change consists of two independent develop-ments that differ in structure and persistence: (1) A slow, monotonic and (presum-ably) permanent ageing effect caused by an increasing life expectancy; (2) a morerapidly changing, non-monotonic and less permanent...

In an a priori view, it is usually assumed that the business cycle of manufacturing industries leads the business cycle of the service sector. This seems to be even more plausible for the relationship between business-related services, whose high growth rates in recent years were largely due to...
