Between 1700 and 1850, English grain yields were substantially higher than those attained in other countries. It is widely believed that yields were constrained by the availability of nitrogen, and that supplies of nitrogen were effectively limited to animal dung produced on the farm. This paper...

Wheat was the single most important product of the British economy during the Industrial Revolution, being both the largest component of national income and the primary determinant of caloric intake. This paper offers new estimates of annual wheat production during industrialisation. Whereas...

The Industrial Revolution in England was characterised by early and rapid labour release from agriculture to industry. This was facilitated by rising levels of labour productivity in agriculture which permitted labour to be released without excessive upward pressure on food prices. New...

Using a large panel of weekly wheat prices, we infer the annual rate of return on capital in each county in England and Wales in the period 1770-1820. Throughout this period markets were efficient in the sense that weekly returns were serially uncorrelated. We show that the interest rate...

We estimate a model of wheat yields for eighteenth century England using village-level data. This is an entirely new approach to quantifying progress during the Agricultural Revolution and enables us to consider both environmental and technological inputs. We find that climate was a crucial...

Interpretation of historic grain price data may be hazardous owing to systematic grain quality variation – both cross sectionally and over varying time horizons (intra-year, inter-year, long run). We use the English wheat market, 1750-1914, as an example to quantify this issue. First, we show...

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...
