INTERNATIONAL TRADE AND GROWTH: AN OVERVIEW FROM THE PERSPECTIVE OF THE NEW GROWTH THEORY AgEcon
Roe, Terry L.; Mohtadi, Hamid.
The role of international trade in the new growth theory is investigated from several perspectives. Following a historical outline and a brief analytical sketch of the R&D based models, the results from fitting three structural models to data are presented. Results show the relative impacts on growth from trade and R&D based policies including technological spillovers from trade. The mechanism of inter-sectoral adjustments to the long-run growth path are also discussed. Results from selected econometric studies are reviewed. With emphasis on agriculture, this includes evidence of technological spillovers from trade, the effect of R&D expenditures on growth in total factor productivity, and the extent to which the stock of technological...

The Environment and Directed Technical Change: Comment AgEcon
Hourcade, Jean-Charles; Pottier, Antonin; Espagne, Etienne.
This paper discusses the growth model with environmental constraints recently presented in (Acemoglu et al., 2011) which focuses on the redirection of technical change by climate policies with research subsidies and a carbon tax. First, Acemoglu et al.'s model and chosen parameters yield numerical results that do not support the conclusion that ambitious climate policies can be conducted “without sacrificing (much or any) long-run growth”. Second, they select unrealistic key parameters for carbon sinks and elasticity of substitution. We find that more realistic parameters lead to very different results. Third, the model leads to an unrealistic conclusion when used to analyse endogenous growth, suggesting specification problems.
