Résumé :

We use a large sample of export transactions from customs files across six developing countries and several years to explore the extent of pricing to market and volume responses to exchange-rate variations in the East African Community (EAC), a customs union, and a control group of exporters from developing countries outside the region. We find that, relative to the control group, EAC exporters seem to have a stronger ability to price to market on the CU market, suggesting the existence of market power. This market power does not seem to relate to usual proxies for firm size, but is more marked for manufactured products. We also find that the supply (volume) response to exchange-rate variations is more subdued for EAC exporters than for the control group, suggesting the existence of supply constraints.

"Uncertainty and Decision in Climate Change Economics" (with Antony Millner, London School of Economics)

Abstract : Uncertainty is intrinsic to climate change : we know that the climate is changing, but not how fast or in precisely what ways. Nor do we understand fully the social and economic consequences of these changes, or the options that will be available for reducing climate change. Furthermore the uncertainty about these issues is not readily quantified and expressed in probabilistic terms : we are facing deep uncertainty or ambiguity rather than risk in the classical sense, rendering the classical expected utility framework of limited value. We review the sources of uncertainty about all aspects of climate change and resolve these into various components, commenting on their relative importance. Then we review the decision-making frameworks that are appropriate given the absence of quantitative probabilistic information, including both non-probabilistic approaches and those based on multiple priors.
