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...

We show that vector error correction models encompass different approaches to analysing market integration; we illustrate our method using English weekly wheat prices, 1770–1820. Price variation decomposes into: (i) magnitude of price shocks; (ii) correlation of price shocks; (iii)...

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...
