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...

Giffen reported that, in the late nineteenth century, English wheat consumption rose when its price increased – the first recorded “Giffen good”. Using Giffen’s data, I explain how he reached his conclusion. I then show that his analysis was faulty: price elasticity of demand appears...

Cointegration analysis has been used widely to quantify market integration through price arbitrage. We show that total price variability can be decomposed into: (i) magnitude of price shocks; (ii) correlation of price shocks; (iii) between-period arbitrage. All three measures depend upon data...

In 1795 the British took control of the Cape colony (South Africa) from the Dutch; and in 1843 they exogenously changed the legal basis of landholding, giving more secure property rights to landholders. Since endowments and other factors were held constant, these changes offer clean tests of the...

We examine prizes as an inducement for innovation using a novel dataset of awards for inventiveness offered by the Royal Agricultural Society of England from 1839 to 1939. At annual shows the RASE held competitive trials and awarded medals and monetary prizes (exceeding one million pounds in...

We estimate a time series model of weather shocks on English wheat yields for the early nineteenth century and use it to predict weather effects on yield levels from 1697 to 1871. This reveals that yields in the 1690s were depressed by unusually poor weather; and those in the late 1850s were...
