Pathways to African Export Sustainability

By: Paul Brenton,Olivier Cadot,Martha Denisse Pierola

African export ventures often fail early, a trend that causes waste, uncertainty, and discouragement. This book shows how governments and donors can help boost African export sustainability through a mixture of traditional policy prescriptions and selected proactive interventions.

The Intensive Margin in Trade

By: Ana Fernandes,Peter J. Klenow,Sergii Meleshchuk,Martha Denisse Pierola,Andres Rodriguez-Clare

The Melitz model highlights the importance of the extensive margin (the number of firms exporting) for trade flows. Using the World Bank’s Exporter Dynamics Database (EDD) featuring firm-level exports from 50 countries, we find that around 50 percent of variation in exports is along the extensive margin—a quantitative victory for the Melitz framework. The remaining 50 percent on the intensive margin (exports per exporting firm) contradicts a special case of Melitz with Pareto-distributed firm productivity, which has become a tractable benchmark. This benchmark model predicts that, conditional on the fixed costs of exporting, all variation in exports across trading partners should occur on the extensive margin. We find that moving from a Pareto to a lognormal distribution allows the Melitz model to match the role of the intensive margin in the EDD. We use likelihood methods and the EDD to estimate a generalized Melitz model with a joint lognormal distribution for firm-level productivity, fixed costs and demand shifters, and use “exact hat algebra” to quantify the effects of a decline in trade costs on trade flows and welfare in the estimated model. The welfare effects turn out to be quite close to those in the standard Melitz-Pareto model when we choose the Pareto shape parameter to fit the average trade elasticity implied by our estimated Melitz-lognormal model, although there are significant differences regarding the effects on trade flows.

Trade in Zimbabwe

Changing Incentives to Enhance Competitiveness

By: Richard Newfarmer,Martha Denisse Pierola

In Zimbabwe, trade has been a driver of economic growth, rising incomes, and progressive empowerment of Zimbabweans through rising standards of living and the promise of better jobs. Since 1980, through good years and bad years, increases in exports have been positively associated with increases in national income. Zimbabwe's location and resource base, together with a low-cost but relatively well educated labor force, have endowed it with a naturally high trade ratio built on a diversified base that facilitates using trade as an engine of growth. While trade volumes have rebounded smartly from the deep recession of 2007-2008, these do not offset other worrisome longer-term trends: • Export growth during the last decade has been lacklustre and failed to drive high growth. • Agricultural exports, other than tobacco, have lost their once dominant role in the region, and are no longer a source of diversification. • Manufacturing has withered in a continuing secular decline. • Zimbabwe’s export basket has become less diversified and more dependent on a narrow range of mineral and, to a lesser extent, agricultural products. In short, exports have become less diversified, less-technologically sophisticated, and less labor-intensive - and ever more dependent on a few large mining activities to provide foreign exchange and employment. This report traces the roots of this poor performance to several policy issues: poor predictability of macroeconomic policy and economic governance has created an unfavorable climate for private investment and trade; a tariff structure that dampens export profitability; industrial policies - indigenization policy in particular - that undermine investor confidence and inhibits private investment; and finally, competition-limiting policies toward services that limit connectivity of Zimbabweans and raise trade costs. The good news arising from the study is that the remedies for these policy shortcomings lie in Zimbabwean hands. If the government were to adopt reforms that reconfigure economy-wide incentives and trade and industrial policies, it could promote sustained growth, economic diversification and empowerment of poor people.
