This paper explores the Kaldorian approach to endogenous growth theory. The central principles of this approach are explored, including the claims that growth is: (a) demand-led, with trade playing a central role in aggregate demand formation; and (b) path-dependent. It is shown that both the...

This work introduces firm heterogeneity in a dynamic model of growth with both process and product innovations. Deliberate R&D is undertaken to create new varieties of products that contribute to welfare through consumer's love of variety. Long-run growth is fuelled by process innovations that...

We develop a model that incorporates salient features of growth in modern economies. We combine the expanding-variety growth model through horizontal innovations with a hierarchy of basic and applied research. The former extends the knowledge base, while the latter commercializes it. Two-way...

A new technology is a bold new combination of production factors that potentially yields a higher level of total factor productivity. The optimal combination of input factors is unknown when an innovation is pursued. A larger targeted innovation may require a greater change in the optimal...

This paper demonstrates that increasing returns to scale can be sustained when agents care about praiseworthiness of their conduct. Unlike the desire to attain approbation from external sources, the notion of praiseworthiness seems to have been neglected by contemporary economic literature. Yet...

This article contributes to the debate on skill-biased technical change by studying the dynamics of skill supply and wage inequality in an endogenous growth model with ability-biased technical progress. Due to a discouragement effect, rising within groups inequality reduces incentives to become...

We contribute to the debate on skill-biased technical change by studying the long-run dynamics of skill premia in an endogenous growth model in which technical change can be directed towards different factors. We show that R&D resources tend to be directed alternately towards skill-intensive and...

Mobile industry is characterized by a sharp fall in megabyte price which highly benefi ts to consumers. This article aims to identify the main parameters that lead to such a fall and shows that the growth of traffic is by far the main cause. It proposes a parametric model that explains the...

We study the welfare consequences of a government regulation that forces a patented equipment to be supplied by n independent producers. On the one hand, such a regulation hurts the value of a patent and therefore reduces activities in the R&D sector. On the other hand, the enhanced competition...

In this paper we build an endogenous growth model where human capital and ideas are complements in the long-run equilibrium and technological progress takes the form of a continuous increase in the number of horizontally differentiated varieties of intermediate inputs. One peculiarity of the...
