The demographic change is one of the most important challenges for many developed economies in the twenty-first century. This paper examines the effect of workforce demographics and the distribution of skills on aggregated productivity and output. Population aging may lead to secular stagnation...

The value chain of the telecommunication industry is subject to a continuing disintegration which is caused by outsourced network operation, the provisioning of wholesale interfaces to competing service providers and the cooperative provisioning of broadband access. Thus, many companies regard...

We present experimental evidence that illuminates the trade-off between efficiency considerations and social identity concerns in an inter-city multilevel public goods game. In total, 616 inhabitants of Heidelberg and Mannheim take part in an online experiment in which they can allocate an...

Structural innovations are typically hidden and often identified by means of a-priori economic reasoning. Under multivariate Gaussian model innovations there is no loss measure available to distinguish between particular identifying restrictions and rotations thereof. Based on a non Gaussian...

This paper complements research on how {\em love of wealth} bears on key variables in a Ramsey-Cass-Koopmans growth framework. It is shown that for an optimum the social planner cannot have an excessive {\em love of wealth}. If the planner has the `right' {\em love of wealth} an optimum exists...

This paper sets up a unified growth model and explores the impact of gender differences in the desire for sex and the distribution of power in the household for the onset of the demographic transition and the take-off to growth. Depending on the price and efficacy of modern contraceptives, the...

We propose a unified growth theory to investigate the mechanics generating the economic and demographic transition, and the role of mortality differences for comparative development. The framework can replicate the quantitative patterns in historical time series data and in contemporaneous...

A core mechanism of unified growth theory is that accelerating technological progress induces mass education and, in interaction with child quantity-quality substitution, a decline in fertility. Using unique new data for 21 OECD countries over the period 1750-2000, we test, for the first time,...
