Using combined data from population censuses and Urban Household Surveys, we study the effects of demographic structural changes on the rise in household saving in China. Variations in fines across provinces on unauthorized births under the one-child policy and in cohort-specific fertility...

This paper studies the aggregate substitution and expansion effects triggered by changes in input prices, in a context where firms supply a homogenous commodity and compete in quantities à la Cournot. We derive a sufficient condition for the existence of a Cournot equilibrium and show that this...

This paper argues that the conventional definition of the elasticity of complementarity is not well suited to deal with the case of increasing returns. It proposes a slightly different formula, that uses a distance function formulation instead of a production function. The proposed definition...

At the firm level, revenue and costs are well measured but prices and quantities are not. This paper shows that because of these data limitations estimates of returns to scale at the firm level are for the revenue function, not production function. Given this observation, the paper argues that,...

Attempts can be found in the DEA literature to identify returns to scale at efficient interior points of the production possibility set on the basis of returns to scale at points of the corresponding reference sets. However, an opposite approach is put forward in this paper, advocating that...

Assessing the migration potential and predicting future migration streams are among the most relevant, yet least well understood topics of migration research. The usual approach taken to address aggregate-level prediction problems is to fit ad hoc specifications to historical data, and to...

Population ageing and decline are inescapable facts for Germany which are expected to have - especially due to the labour force decrease - negative impacts on the economy. In this context it is often referred to the possibility of countering potentially negative economic effects of population...

This study investigates the influence of the demographic ageing process in Germany on the long-term economic growth path. For this purpose a macroeconomic simulation model which combines demographic forecasts with a modified Ramsey growth model is applied. Special focus is put on the consumption...

This paper considers a setting in which the acquisition of human capital entails a change of location in social space that causes individuals to revise their comparison groups. Skill levels are viewed as occupational groups, and moving up the skill ladder by acquiring additional human capital,...
