Ben Muse links to a pair of interesting World Bank papers about exports and development that were recently posted. Nicita (2006) evaluates the impact of Madagascar’s growing textile export industry upon its poor (in short, urban skilled laborers gain the most from the sector’s expansion). Djankov, Freund, and Pham (2006, pdf) examine the impact of administrative delays upon export volume (hint: rent-seeking opportunities greatly reduce exports).
