This paper presents an endogenous growth model of directed technical change with vertical and horizontal R&D to study an analytical mechanism that is consistent with the coexistence of aggregate stability and structural change. We focus on changes in the share of the high- versus the low-tech...

This paper analyses the e¤ect of a resource discovery on an open economy with endogenous directed technical change. Technical progress depends on entrepreneurs who produce (or adopt) technology, and endogenously choose which sector to operate in. The static e¤ect of a resource discovery is de-...

We analyze a multi-sector growth model with directed technical change where man-made capital and exhaustible resources are essen- tial for production. The relative profitability of factor-specific inno- vations endogenously determines whether technical progress will be capital- or...

Sectoral data features (i) changing relative expenditures of different sectors, (ii) non-constancy in relative prices and (iii) long-run trends in relative TFP growth rates across sectors. We provide a tractable theory of industry directed technical change, which is able to reconcile these...

This paper reports research focused on the inter-temporal resource allocation requirements of a program of technological changes that would halt global warming by completing the transition to a "green" production regime (i.e., zero net CO2-emissions) within the possibly brief finite interval...

We analyze recent contributions to growth theory based on the model of expanding variety of Romer [Romer, P. (1990). “Endogenous technological change”. Journal of Political Economy 98, 71–102]. In the first part, we present different versions of the benchmark linear model with imperfect...
