A monotonicity conjecture for real cubic maps

This is an outline of work in progress. We study the conjecture that the topological entropy of a real cubic map depends ``monotonely'' on its parameters, in the sense that each locus of constant entropy in parameter space is a connected set. This material will be presented in more detail in a later paper

Impacts of the EU sugar policy reforms on developing countries

This report analyses the impacts of the Commission's July 2004 proposal for sugar policy reforms on developing countries. The study uses three approaches that complement each other: model simulations, literature review and country case studies. Model simulations indicate that the consequences of the EU policy reform on EU imports are rather modest: imports from LDCs increase but to a lesser extent than the Commission and other studies indicate. Important trigger points in the evaluation of the impact on trade flows are the degree of substitutability between domestic EU sugar and imported sugar, and potential 'swap' or trade diversion effects. Welfare effects are minor to ACP countries as a group, but country effects may differ strongly. The study includes three case studies - Ethiopia, Mauritius and Brazil, representing an EBA, an ACP and a net exporting country with no preferences to the EU market - to show how EU policy changes may affect the sugar industry in each of these countries.Agricultural and Food Policy,
