Abstract
How large are the bene ts of transportation infrastructure projects, and what explains
these bene ts? To shed new light on these questions, this paper uses archival data from
colonial India to investigate the impact of India's vast railroad network. Guided by four
predictions from a general equilibrium trade model, I nd that railroads: (1) decreased
trade costs and interregional price gaps; (2) increased interregional and international
trade; (3) increased real income levels; and (4), that a sucient statistic for the e ect
of railroads on welfare in the model (an e ect that is purely due to newly exploited
gains from trade) accounts for virtually all of the observed reduced-form impact of
railroads on real income in the data. I nd no spurious e ects from over 40,000 km of
lines that were approved but|for four di erent reasons|were never built.
我第一次看到这篇论文的时候还不知道它已经投到了ARE，但觉得非常有趣味性，而且做了大量工作，值得分享给大家。
我们可以与另外一篇论文On the Road对比着读。https://bbs.pinggu.org/thread-1113189-1-1.html
