No wheat crisis: trade liberalization and transportation innovation in Quebec during the 1830s and 1840s
研究了19世纪上半叶下加拿大小麦生产崩溃的原因，发现主要是1831年殖民地贸易法案带来的贸易冲击和加拿大殖民地间运费下降导致的调整，而非土壤枯竭或文化保守主义。
Abstract In the first half of the nineteenth century, the wheat oriented agrarian economy of Lower Canada saw a rapid collapse in wheat production. These developments have been blamed on factors ranging from soil exhaustion to cultural conservatism and used to infer falling living standards in the colony. We provide evidence suggesting this collapse was largely the result of adjustment to the trade shock that followed the Colonial Trade Act of 1831 and a rapid reduction in freight costs between the Canadian colonies. Areas more exposed to external markets—as proxied by road access—shifted away from wheat production.
