This paper characterizes the short- and long-run Cournot equilibrium with heterogeneous firms and stochastic technological change. In our model, firms have different technologies with heterogeneous fixed and variable costs and various degrees of markups. In a framework with homogeneous firms,...

We study the impact of office and computing machinery (OCM) on the demands for workers with different educational levels. The empirical analysis relies on a system of demand equations that nests the translog, the generalised Leontief and the normalised quadratic specifications. Using panel data...

In order to simplify the representation of a technological relationship between inputs and outputs, a production unit's technology must typically satisfy some restrictive conditions, some of them being well known in the literature. This paper presents new results for aggregating labour inputs...

Birth rates differ strongly across European states, despite the deep economic harmonisation process related to European integration. This study uses large scale administrative data from France and Germany to analyse and directly compare fertility patterns in two major European economies over a...

This paper examines the effects that purchased services and imported intermediate materials have on the labour demand for different skills in the manufacturing sector. We derive and estimate a factor demand system based on the generalised Box-Cox cost function nesting both the normalised...

This paper derives the structure of a production function which is necessary and sufficient for generating a fixed cost. We extend the classical production function in order to allow each input to have a fixed and a variable part. We characterize and estimates both fixed and variable components...

Obvious differences between countries regarding their economic performance have led to the question whether the size, structure, and organisation of the public sector contribute to cross-country income levels and growth gaps. Public sector activities may have an effect on overall productivity...
