We scrutinize the impact of international productivity gains (spillovers) induced by imports and exports on optimal tariffs. First, we solve a stylized 2x2 trade model of a large open economy and show that (a) productivity gains via exports and imports both reduce the strategically optimal...

This North-South model of Schumpeterian endogenous growth combines a market, productivity and knowledge effect. A set of various convergent and divergent growth paths is derived that is much richer than in the literature so far. South-North convergence based on North-South technology diffusion...

Concerns have been raised that demographic ageing may weaken the competitiveness of knowledge-based economies and increase regional disparities. The age-creativity link is however far from clear at the aggregate level. Contributing to this debate, we estimate the causal effect of the workforce...

Numerous studies have evaluated the effect of nutrition early in life on health much later in life by comparing individuals born during a famine to others. Nutritional intake is typically unobserved and endogenous, whereas famines arguably provide exogenous variation in the provision of...

Demographic change is expected to affect labour markets in very different ways on a regional scale. The objective of this paper is to explore the spatio-temporal patterns of recent distributional changes in the workers age structure, innovation output and skill composition for German regions by...

This paper investigates the long-run relationships between the size and age composition of a city's population and the price of local housing. For estimation purposes, we combine city-level demographic information with housing price data for 87 cities in Germany over the period 1995-2012....

In most industrialised countries, the workforce is ageing rapidly. If ageing workforces affect sectors differently, the total impact of ageing will depend on the industrial structure of an economy. This paper measures the impact of changes in the age structure of establishments on productivity...

In this study, we investigate the effect of five specific human resource measures for old employees (SMOE) on their relative productivity. Despite the fact that SMOE are applied in the majority of establishments, this is the first representative study on the effectiveness of these measures. We...

We exploit the cross?country and time variation in the demographics and education structure of 11 European countries to study how cohort size has affected real earnings in Europe. When we pool the data of all countries, we find that cohort size has a negative and statistically significant effect...

The paper surveys the state of German pension system after a sequence of reforms aimed at achieving long-term sustainability. We argue that the latest reforms have moved pension provision in Germany in principle from a defined benefit to a defined contribution scheme, and that this move has...
