This analysis employs cointegration methods and semiparametric regression in order to assess the integration of maize markets and the factors determining national and cross-national transmission of price signals in Sub-Saharan Africa. We use a rich dataset of 16 series of wholesale maize prices...

We study backstop adoption and carbon dioxide emission paths in a two-region model with unilateral climate policy and non-renewable resource consumption. The regions have an equal endowment of the internationally tradable resource and a backstop technology. We first study the case of a...

Well-intended policies aimed at reducing greenhouse gas emissions may have unintended undesirable consequences. Recently, a large literature has emerged showing under what conditions this so-called ‘Green Paradox’ may occur. We review this literature and identify the key mechanisms behind...

Has the Kyoto Protocol induced carbon leakage? We conduct the first empirical ex-post evaluation of the Protocol. We derive a theoretical gravity equation for the CO2 content of trade, which accounts for intermediate inputs, both domestic and imported. The structure of our new panel database of...

This paper develops a model of trade and CO2 emissions with heterogenous firms, where firms make abatement investments and thereby have an impact on their level of emissions. The model shows that investments in abatements are positively related to firm productivity and firm exports. Emission...

Carbon tariffs are one prominently discussed climate policy. The proponents stress the carbon tariffs’ ability to restore competitiveness, avoid carbon leakage, and reduce world carbon emissions. We analyze the effects of carbon tariffs on trade, welfare, and carbon emissions in a structural...

This paper studies the relationship between export policy and food prices. We show that, when individuals are loss averse, food exporters may use trade policy to shield the domestic economy from large price shocks. This creates a complementarity between the price of food in international markets...

This article presents a Ricardian model of trade with learning-by-doing to study the effect of barriers to trade in products with low growth potential on the long-run economic growth. The model shows that, when elasticity of demand for the product with a lower learning potential is lower than...

The SSM is a proposal from the G-33 Group in the Doha Round negotiations in which developing countries would be allowed to use contingent tariffs to control import surges of food commodities and/or downward spikes in their border prices. The principal objective is to safeguard the livelihood...

In the basic model of international environmental agreements (IEAs) (Barrett 1994, Rubio and Ulph 2006) extended by international trade, self-enforcing - or stable - IEAs may comprise up to 60% of all countries (Eichner and Pethig 2013). But these IEAs reduce total emissions only slightly...
