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...

R&D-based growth theory suggests that a larger population size raises either the long-run rate of economic growth (strong scale effect) or the level of per capita income (weak scale effect), with far-reaching policy implications. However, for modern times there is little empirical support for...

In the paper, the sources of productivity growth are investigated by an empirical analysis with micro data for West-German manufacturing firms. The theoretical framework corresponds to an augmented growth accounting approach based on a production function. The empirical results reveal that...

In his 1966 Inaugural Lecture at Cambridge, entitled On the Causes of the Slow Rate of Economic Growth in the UK, the Hungarian-born British economist, Nicholas Kaldor presented a series of "laws" to account for the growth rate differences between Britain on the one hand, and the more successful...

We examine the contribution of human capital to economy-wide technological improvements through the two channels of innovation and imitation. We develop a theoretical model showing that skilled labor has a higher growth-enhancing effect closer to the technological frontier under the reasonable...

This paper analyses macroeconomic aspects of exit from aid-dependence. By 'exit from aid', we mean substantial and enduring decline over time in Official Development Assistance (ODA) as a share of Gross Domestic Product (GDP). The relevant macroeconomic variables are identified by systematically...
