We provide a general theoretical characterization of how technology choice affects the long-run elasticity of substitution between capital and labour. While the shape of the technology frontier determines the long-run growth path and the long-run elasticity, adjustment costs in technology choice...

We present a simple production technology in which the choice of production technique results in a balanced growth path even in the presence of capital-augmenting technical progress. Given a particular choice of technique, the production function is CES with a less than unitary elasticity of...

We show that allowing firms a choice of CES production techniques (via the distribution parameter between capital and labor) can result in a new class of production functions that produces short-run capital-labor complementarity but yields a long-run unit elasticity of substitution. This is...

Empirical studies on aggregate export behaviour have recently emphasised the role played by innovation as the main force driving product differentiation and competitiveness for developed countries. These studies treat foreign innovation as a variable that affects negatively national export...

One of the key determinants of potential growth are productivity gains. Total factor productivity (TFP) differences are the main determinant of per capita income differences between countries. A key factor to understand TFP is misallocation: the aggregate productivity loss from microeconomic...

This paper presents an extended model of cumulative growth in which the effects of innovation and catching-up are considered. The effect of innovation adds another source of cumulative growth to that of the traditional models and allows for the consideration of the importance of non-price...
