We present a multi-country theory of economic growth in which countries are connected by a network of mutual knowledge exchange. Knowledge in any country depends on the human capital of the countries it exchanges knowledge with. The diffusion of knowledge throughout the world explains a period...

This paper introduces the Small World model (Watts and Strogatz, Nature, 1998) into the theory of economic growth and investigates how increasing economic integration affects firm size and effciency, norm enforcement, and aggregate economic performance. When economic integration is low and local...

We propose an innovation-driven growth model in which education is determined by family background and cognitive ability. We show that compulsory schooling can move a society from elite education to mass education, which then triggers market R&D. This means that our model rationalizes two...

This paper integrates into public economics a biologically founded, stochastic process of individual ageing. The novel approach enables us to investigate the interaction between health and retirement policy in order to quantitatively characterize the optimal joint design of the social insurance...

Für bestimmte Berufsgruppen untersuchen wir Gesundheit und Altern vor und nach der Pensionierung. Wir verwenden fünf Wellen des Survey of Health, Aging, and Retirement in Europe (SHARE) und erstellen einen Gebrechlichkeitsindex für ältere Männer und Frauen aus 10 europäischen Ländern....

We propose a model of aging and health deficit accumulation model with an infinite time horizon and a steady state of constant health. The time of death is uncertain and endogenous to lifestyle and health behavior. This setup can be conceptualized as a strive for immortality that is never...

In this paper we set up an overlapping generations model of gerontological founded human aging that takes the interaction between R&D-driven medical progress and access to health care into account. We use the model to explore potential futures of human health and longevity. For the baseline...

It is a well known fact that economic development and distance to the equator are positively correlated variables in the world today. It is perhaps less well known that as recently as 1500 C.E. it was the other way around. The present paper provides a theory of why the "latitude gradient"...

We discuss public pension systems in a multi-period overlapping generations model with gerontologically founded human aging and a special focus on occupation-specific morbidity and mortality. We examine how distinct replacement rates for white-collar and blue-collar workers and early retirement...

Successful economic development is usually characterized by two salient phenomena: industrialization and demographic transition. Chronologically both events happen so closely to each other that historians and economists alike suspect that they are interrelated. This paper develops a theory for...
