Do intermediate goods help explain relative and aggregate productivity differences across countries? Three observations suggest they do: (i) intermediates are relatively expensive in poor countries; (ii) goods industries demand intermediates more intensively than service industries; (iii) goods...

Funding adaptation requires adequate governance and there are different ways to organise and channel the funds to where it is most efficient and most necessary. This paper investigates this issue and studies the practical implementation of a development under conditionality, namely...

The paper develops a model in which a country with better technology for abatement of Green House Gas (GHG) emission (the North) commits to an international protocol to keep the global GHG emission within a specified limit while it helps the mitigation effort in the other country (the South)...

The United Nations General Assembly declared 2012 the “International Year of Sustainable Energy for All”, officially recognising the urgent need to put energy at the centre of the global development agenda. In parallel, a strong international policy effort is being made to achieve the goal...

The paper considers a situation where two countries – the North and the South – use a non-traded polluting input to produce the goods for final consumption. The North is more efficient in both, production and abatement processes. The study compares the effects of the transfer of abatement...

This paper examines the macroeconomic effects of an environmental tax reform in a growing economy. A model of endogenous growth based on human capital accumulation is used to numerically simulate the growth effects of different environmental tax reforms and compute their impact on welfare in the...

This paper looks at the interplay between human capital and innovation in the presence of climate and educational policies. Using recent empirical estimates, human capital and general purpose R&D are introduced in an integrated assessment model that has been extensively applied to study climate...

Given disparate beliefs about economic growth, technical change and damage caused by climate change, this paper starts with the seeming impossibility of determining a unique time profile of the social costs of carbon as a benchmark for climate negotiations and for infrastructure decisions that...

Is pollution a dirty word? To answer this question we develop an endogenous growth model à la Rebelo (1991) where dirtiness becomes a fundamental choice variable for the economy to grow. Conclusions to our analysis say that a positive sustainable economic growth is attainable only if polluting...

WITCH – World Induced Technical Change Hybrid – is a regionally disaggregated hard-link hybrid global model with a neoclassical optimal growth structure (top-down) and a detailed energy input component (bottom-up). The model endogenously accounts for technological change, both through...
