Development economics in retrospect and prospect
回顾1990年以来发展经济学的巨变：发展中国家概念过时，多数穷国已趋同于富国；剩余领域聚焦未走上趋同之路的少数穷国，学科重心转向新经济地理、定量实证和新政治经济学，经济心理学也有机会。
Development economics has changed radically since 1990. The very concept of ‘developing countries’ has become antiquated as most previously poor countries have converged on rich ones, becoming less distinctive in consequence. The remaining domain of a distinctive development economics is the minority of poor countries that are not securely on a path to convergence. In addition, intellectual fashions have radically shifted. The previous focus on macro-structural issues has given way to new economic geography, quantitative empiricism, and new political economy, with considerable opportunities for economic psychology.
