The Policy Research Working Paper Series disseminates the findings of work in progress to encourage the exchange of ideas about development issues. An objective of the series is to get the findings out quickly, even if the presentations are less than fully polished. The papers carry the names of the authors and should be cited accordingly. The findings, interpretations, and conclusions expressed in this paper are entirely those of the authors. They do not necessarily represent the views of the International Bank for Reconstruction and Development/World Bank and its affiliated organizations, or those of the Executive Directors of the World Bank or the governments they represent.

Mitigating the impact of the economic crisis will require using all the tools necessary to regain a sustainable path to growth. This includes measures to support trade expansion, including in developing countries, such as those in Africa. This paper provides context for understanding why trade facilitation and lowering trade costs matter to Africa both today and over the long term. Trade costs are higher in Africa than in other regions. Using gravity-model estimates, the authors compute ad-valorem equivalents of improvements in trade indicators for a sample of African countries. The evidence suggests that the gains for African exporters from cutting trade costs half-way to the level of Mauritius has a greater effect on trade flows than a substantial cut in tariff barriers. As an example, improving logistics so that Ethiopia cuts its costs of trading a standardized container of goods half-way to the level in Mauritius would be roughly equivalent to a 7.6 % cut in tariffs faced by Ethiopian exporters across all importers. *

Using a new database on standards in China, we estimate the impact of voluntary and mandatory standards -either harmonized to international norms or purely domestic -on Chinese food exports. The dataset covers seven Chinese products over the period 1992-2008. We find that standards have a positive effect on China's export performance, as the benefits to standardization in terms of reducing potential information asymmetry and signaling enhance food safety, and quality in foreign markets seem to surpass compliance costs. Our estimation results show that the positive effect of Chinese standards is larger when they are harmonized to international measures. The results suggest that there are clear benefits to China's steps to base their domestic standards and regulations on international measures.
