Production risks in agriculture due to biotic elements such as pests create biodiversity effects that impede productivity. Pesticides reduce these effects but are damaging for the environment and human health. When regulating farming practices, governments weigh these side-effects against the competitiveness of their agriculture. In a Ricardian two-country setup, we show that free trade results in an incomplete production specialization, that restrictions on pesticides are generally more stringent than under autarky and that trade increases the price volatility of crops produced by both countries and some of the specialized crops. If biodiversity effects are large, the price volatility of all crops is larger than under autarky.

We examine the importance of production risks in agriculture due to biotic elements such as pests in determining the pattern of trade and the distribution of prices in a Ricardian two-country setup. These elements create biodiversity eff ects that result in an incomplete specialization at the free trade equilibrium. Their influence on idiosyncratic production risks evolves depending on the countries' openness to trade. Pesticides allow these eff ects to diminish but they are damaging for the environment and human health. When regulating farming practices, governments have to counterbalance these side-eff ects with the competitiveness of their agricultural sector on international markets. Nevertheless, restrictions on pesticides under free trade are generally more stringent than under autarky.

The new European Commission, chaired by Ursula Von der Leyen, has made the environment and climate the central parameters of European policy, both internal and international, for the period 2020-2025. As such, the European Green Deal has set itself the goal of making Europe the "first climate neutral" continent by 2050. It has been five years since the Paris Agreements was agreed. This working Paper analyzes the trade policy options available to the EU for a low-carbon international trading system.

Nous analysons l'impact et les déterminants d'une taxe carbone globale dans une économie imparfaitement intégrée composée de pays de différente taille. A l'aide d'un modèle de commerce et de localisation, nous montrons tout d'abord que la concentration de firmes dans le pays disposant d'un avantage de taille de marché accroît les émissions totales de CO2. L'intro- duction d'une taxe carbone globale conduit alors à des délocalisations de fi…rmes du grand pays vers le petit pays de sorte que même …fixée à un taux unique, une …fiscalité carbone ne serait pas neutre du point de vue de la géographie économique. Enfin, parce qu'elles conduisent à une réduction des émissions mondiales de CO2, ces relocalisations améliorent l'efficacité environnementale de la taxe carbone.

This paper investigates the ability of a fully harmonized carbon tax to curb carbon emissions in a globalized economy characterized by an uneven spatial distribution of heterogeneous firms. The level of the carbon tax matters for the direction of the relocation and its impact on global emissions. When the carbon tax is low enough, emissions are reduced as firms relocate to the smaller country to pay lower taxes by reducing their output. If the carbon tax is too high, then firms react by relocating to the larger country to maintain their export activity, so that the most environmentally friendly spatial configurations can be removed.
