Communication Infrastructure and Stabilizing Food Prices: Evidence from the Telegraph Network in China
- (pp. 65-101)
Abstract
This paper exploits a unique historical setting―the expansion of the telegraph network in nineteenth-century China when railroads were limited―to examine whether the reduction of information frictions stabilizes grain prices. Employing a difference-in-difference (DID) strategy, we find that the telegraph access (i) reduced both the magnitude and the incidence of extreme prices; (ii) mitigated price responses to local weather shocks but increased the responsiveness to shocks in other telegraph-connected regions; (iii) affected the price volatility in a mean-reverting pattern; i.e., volatility rose in previously price-stable regions, and volatility decreased in price-unstable regions.Citation
