Abstract

From 1770 to 1914, the British Government collected weekly price and quantity data for all types of grain traded in many market towns; these ?Corn Returns? were published in the London Gazette. We computerised the data published 1770-1864, totalling around 6 million data points. Here we describe the nature of these data; discuss why, when and how they were collected; consider their accuracy and biases; describe how we computerised them; and offer caveats in using these ? and similar ? data. We highlight the problem of drawing valid inferences in the face of price impact from fluctuating grain quality and rising imports.
