The geographical sources of innovation of firms have been hotly debated. While the traditional view is that physical proximity within city-regions is key for the innovative capacity of firms, the literature on ‘global pipelines’ has been stressing the importance of establishing communication...

The outcome of the 15th conference of the Parties to the UNFCC showed a shift from a top-down approach with a collective target favoring environmental objectives to a bottom-up accord favoring political feasibility with no meaningful binding agreement in sight as the global climate regime and...

We estimate how random weather fluctuations affected infant mortality across 28 African countries in the past, combining high-resolution data from retrospective fertility surveys (DHS) and climate-model reanalysis (ERA-40). We find that infants were much more likely to die when exposed in utero...

We propose a dynamic spatial theory to analyze the geographic impact of climate change. Agricultural and manufacturing firms locate on a hemisphere. Trade across locations is costly, firms innovate, and technology diffuses over space. Energy used in production leads to emissions that contribute...

Tropical deforestation accounts for almost one-fifth of greenhouse gas emissions worldwide and threatens the world's most diverse ecosystems. The prevalence of illegal forest extraction in the tropics suggests that understanding the incentives of local bureaucrats and politicians who enforce...

This paper examines future energy and emissions scenarios in China generated by the Integrated Assessment Model WITCH. A Business-as-Usual scenario is compared with five scenarios in which Greenhouse Gases emissions are taxed, at different levels. The elasticity of China’s emissions is...

This paper builds a two-country (North, South), two-sector (polluting, nonpolluting) trade model with directed technical change, examining whether unilateral environmental policies can ensure sustainable growth. The polluting good is produced with a clean and a dirty input. I show that a...
