Econometric work by Jean-Daniel Boyer, Magali Jaoul-Grammare, and Sylvie Rivot (all participating)  has shed new light on price formation in eighteenth century French grain markets, indicating how their results can inform our understanding of contemporary arguments regarding price movements and policy appropriate for either moderating fluctuations, or compensating for them. We aim to generalise some aspects of their work both in regard to contemporary debate and in respect to the assembly of adequate data sets and the application to them of appropriate analytical techniques. Gauthier Lanot (Umeå) and Marten Seppel (Tartu) are also participating.
