Does population aging and the associated increase in the old-age dependency ratio affect economic growth ? The answer is given in a novel analytical framework that allows for population aging to affect endogenous capital- and labor-saving technical change. The short-run analysis reveals that...

We study the effect of a declining labor force on the incentives to engage in labor-saving technical change and ask how this effect is influenced by institutional characteristics of the pension scheme. When labor is scarcer it becomes more expensive and innovation investments that increase labor...

Uzawa’s steady-state growth theorem (Uzawa (1961)) is generalized to a neoclassical economy that uses current output, e. g., to create technical progress or to manufacture intermediates. The difference between aggregate final-good production and these resources is referred to as net output....

The Inada (1963) conditions constitute a defining property of the neoclassical production function with capital and labor as arguments. Are these conditions justifiable on economic grounds? Yes, they are: we show that a production function with positive, yet diminishing marginal products and...

We study the link between public enforcement of property rights, innovation investments, and economic growth in an endogenous growth framework with an expanding set of product varieties. We find that a government may assure positive equilibrium growth through public employment in the enforcement...

Von dem vierten Gesetz für moderne Dienstleistungen am Arbeitsmarkt (Hartz IV), das mit dem 1. Januar 2005 in Kraft trat, erhoffte sich der Gesetzgeber eine Stärkung der Anreize, Arbeit anzubieten. Dieser Aufsatz analysiert die Beschäftigungswirkungen einer Senkung staatlicher...

In a neoclassical economy with endogenous capital- and labor-augmenting technical change the steady-state growth rate of output per worker is shown to increase in the elasticity of substitution between capital and labor. This confirms the assessment of Klump and de La Grandville (2000) that a...

We study the impact of an offshore financial center on the economy in the presence or absence of bank secrecy in a two-country setting with heterogeneous investors who choose where to deposit their savings. Rather than focussing on tax competition, we acknowledge that countries use two...

We study how the level of trade costs and the intensity of competition interact to explain the nature and intensity of trade within a given industry and the location of firms across countries. As trade costs decrease from very high to very low values, the global economy moves from autarky to...
