“…Nevertheless, we analyze the wheat market for the following reasons: The most important one is that the modern literature on the suspension of the Berlin produce exchange use wheat prices (e.g., Jacks, 2007). Additionally, the related literature on the integration of early commodity markets (see, e.g., Bateman, 2011; Sharp & Weisdorf, 2013; Uebele, 2011), and on the influence of speculation in commodity markets (see, e.g., Gilbert & Pfuderer, 2014; Hamilton & Wu, 2015; Irwin & Sanders, 2011, 2012; Kim, 2015; Manera et al, 2013, 2016) is usually based on or incorporates wheat prices, while rye is used much less frequently. In an effort to provide comparability and continuity with the literature, we therefore rely on an analysis of wheat prices.…”
