Constructing an agricultural output series requires a rational economic basis on which to convert one crop into another, and a conversion method using only the information which we have at our disposal. The traditional method fails on both counts. We develop two alternative methods. The first is...

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...

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...

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...

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...

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...
