Market integration of European inland regions such as Germany caught up on North-Western Europe from the seventeenth century onwards. As many studies rely on grain prices and the pre-industrial era was a period of climate change, a relevant question is in how far changing weather shocks impact on the measurement of convergence trends. We create a new high-quality grain price dataset and apply four methodologies to quantify market integration robust to weather shocks and climate change. Population growth and river transport turn out as plausible explanations for price convergence rather than climate change.

工业化前德国的气候变化、天气冲击和价格趋同

从 17 世纪起，德国等欧洲内陆地区的市场一体化赶上了西北欧。由于许多研究依赖于谷物价格，而前工业时代是一个气候变化时期，一个相关的问题是天气冲击的变化对收敛趋势的测量有多大影响。我们创建了一个新的高质量谷物价格数据集，并应用四种方法来量化市场整合对天气冲击和气候变化的稳健性。人口增长和河流交通成为价格趋同而非气候变化的合理解释。
