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...

Unified growth theory predicts that the timing of the fertility transition is a key determinant of contemporary comparative development, as it marks the onset of the take-off to sustained growth. Neoclassical growth theory presupposes a take-off, and explains comparative development by...

Workers in the US and other developed countries retire no later than a century ago and spend a significantly longer part of their life in school, implying that they stay less years in the work force. The facts of longer schooling and simultaneously shorter working life are seemingly hard to...

Most of the discussion about fiscal stimulus focuses on the multiplier of government spending on impact. In this paper we shift the focus to the multiplier at the end, i.e. to the period in which a deficit spending program terminates. We show that recent time series analyses as well as models of...

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...

During the World Cup 2006 Germany experienced a surge of revealed patriotism unseen so far after World War II. How can this unexpected and spontaneous change of social behavior be explained given that preference (for patriotism) are stable over time? This essay introduces and discusses three...

This paper provides a unified growth theory, i.e. a model that explains the very long-run economic and demographic development path of industrialized economies, stretching from the pre-industrial era to present-day and beyond. Making strict use of Malthus' (1798) so-called preventive check...

In the present paper we advance a theory of pre-industrial growth where body size and population size are endogenously determined. Despite the fact that parents invest in both child quantity and productivity enhancing child quality, a take-off does not occur due to a key "physiological check":...

This note extends the theory of optimal aging and death (Dalgaard and Strulik, 2010) towards uncertain death. Specifically, it is assumed that at any age the probability to survive depends on the number of health deficits accumulated. It is shown that the results in Dalgaard and Strulik (2011)...

This study presents a novel view on education and health behavior of individuals constrained by aging bodies. The aging process, i.e. the accumulation of health deficits over time, is built on recent insights from gerontology. The loss of body functionality, which eventually leads to death, can...
