Episodes of major market volatility are rarely out of the headlines today. Their ramifications, though considerable, are discussed as if these were somehow new, and that they are the result of how economies are structured in our globalised world. Yet prices in international markets in the late middle ages could be just as volatile and have just as far-reaching consequences.

The wine trade between Gascony and England is one key example. Gascony, in modern southwestern France, was part of the medieval duchy of Aquitaine: a territory ruled by the English crown almost without interruption from 1154 to 1453.

Geography and geology permitted the production of just one commodity, wine, and as a result the region was dependent, like so many modern states specialised in fossil fuels or mining, on export earnings to pay for the purchase and import of food and all other goods from distant markets.

My research provides a better understanding of the possible factors that influenced fluctuations in prices, and their knock-on effects. To achieve this, I use wholesale prices in Bordeaux and Libourne from between 1337 and 1466, largely sourced from surviving original documents stored both in the Archives départementales de la Gironde in Bordeaux and the National Archives in London.

As today, extreme climactic events, as well as disruption by war, or demographic catastrophes such as disease or famines, can be understood to cause sudden shifts in supply. Likewise there were abrupt changes in local demand, for example, in 1356 the arrival of a victorious Edward, the Black Prince, with his army laden with ransoms and plunder after the battle of Poitiers, can be observed in the data.

Volatility was exacerbated by government intervention: particularly a 1353 English law that had constrained certain merchants from buying up stock in advance at pre-agreed prices, as would be done in modern markets. Likewise, ill-considered price controls at retail in England probably caused suppressed trade.

Critically, wine was a luxury in northern European ale-drinking societies, where only the rich would tolerate high prices, so any brief disruptions in supply or local demand disproportionately affected the level of exports.

Such characteristics also meant that wine prices were responsive to wider economic shocks in ways that would be well understood today. Monetary policy mattered. England and Gascony used different currencies with a changing exchange rate. As the Gascon livre appreciated against sterling in the two decades after the Black Death (1348-9), prices rose for foreign buyers, then later devaluations, such as in c.1370, 1413-4 and c.1440, made purchases suddenly cheaper, and triggered noticeable increases in English wine imports.

Yet, for Gascony, as in Venezuela today, an over-dependence on foreign imports meant such surges or falls in the value of one single exported commodity resulted in sudden strong trade surpluses or deficits. Foreign currency, then in the form of precious metals, poured in and out of the economy with fluctuations in the wine trade.

This made prices, and by extension, the duchy of Aquitaine’s whole economy, even more unstable. In the end inflation set in as production declined and later years of English Gascony were mired in an economic depression that contributed to the region’s loss to the French crown in 1453 at the end of the Hundred Years’ War.

Late Marriage as a Contributor to the Industrial Revolution in England

A central question of economics is why some nations experienced economic growth and are now rich, when others have not and are poor. We go some way to answering this core question by estimating and testing a model of the English economy beginning four or five centuries before the first Industrial Revolution. Western Europe experienced the earliest modern economic growth and also showed a uniquely high female age at first marriage – around 25 – from at the latest the 15th century. Whereas real wages actually began a sustained rise during the first Industrial Revolution, without the contribution of late marriage, average living standards in England would not have risen by 1870.

We utilise long time series evidence, some dating back to 1300, and test the hypothesis that this West European Marriage Pattern was an essential reason for England’s precocious economic development. Persistent high mortality in the 14th and 15th centuries and massive mortality shocks such as the Black Death lowered life expectations. Subsequently as survival chances improved, especially for children, a given completed family size could be achieved with a smaller number of births. In an environment without artificial birth control, a rise in the age at first marriage of females ensured this reduction in fertility.

Later marriage not only constrained the number of births but also provided greater opportunities for female informal learning, especially through ‘service’. A high proportion of unmarried females between the ages of 15 and 25 left home and worked elsewhere, instead of bearing children, as in other societies. This widened female horizons compared with a passage from the parental household directly into demanding motherhood and housekeeping. Throughout this period the family was the principal institution for educating and training future workers. Schooling was not compulsory until 1880 in England. In the early nineteenth century few children attended any school regularly and few remained at school for more than one and a half years. Such skills and work discipline as were learned were passed on and built up over the generations primarily by the family. Our paper shows how, over the centuries, the gradual rise of this human capital raised productivity and eventually brought about the Industrial Revolution.

Over past centuries marriage and the family were an important engine of economic growth. Whether they still have any comparable contribution in an economy where the state has assumed so much responsibility for education and training remains an open question.        .

Safe-haven asset: property speculation in medieval England

by Adrian Bell, Chris Brooks and Helen Killick (ICMA Centre, University of Reading)


While we might imagine the medieval English property market to have been predominantly ‘feudal’ in nature and therefore relatively static, this research reveals that in the fourteenth and fifteenth centuries, it demonstrated increasing signs of commercialisation.

The study, funded by the Leverhulme Trust, finds that a series of demographic crises in the fourteenth century caused an increase in market activity, as opportunities for property ownership were opened up to new sections of society.

Chief among these was the Black Death of 1348-50, which wiped out over a third of the population. In contrast with previous research, this research shows that after a brief downturn in the immediate aftermath of the plague, the English market in freehold property experienced a surge in activity; between 1353 and 1370, the number of transactions per year almost doubled in number.

The Black Death prompted aristocratic landowners to dispose of their estates, as the high death toll meant that they no longer had access to the labour with which to cultivate them. At the same time, the gentry and professional classes sought to buy up land as a means of social advancement, resulting in a widespread downward redistribution of land.

In light of the fact that during this period labour shortages made land much less profitable in terms of agricultural production, we might expect property prices to have fallen.

Instead, this research demonstrates that this was not the case: the price of freehold land remained robust and certain types of property (such as manors and residential buildings) even rose in value. This is attributed to the fact that increasing geographical and social mobility during this period allowed for greater opportunities for property acquisition, and thus the development of property as a commercial asset.

This is indicated by changes in patterns of behaviour among buyers. The data suggest that an increasing number of people from the late fourteenth century onwards engaged in property speculation – in other words, purchase for the purposes of investment rather than consumption.

These investors purchased multiple properties, often at a considerable distance from their place of residence, and sometimes clubbed together with other buyers to form syndicates. They were often wealthy London merchants, who had acquired large amounts of disposable capital through their commercial activities.

The commodification of housing is a subject that has been much debated in recent years. By exploring the origins of property as an ‘asset class’ in the pre-modern economy, this research draws inevitable comparisons with the modern context: in medieval times, much as now, ‘bricks and mortar’ were viewed as a secure financial investment.

From The Conversation: No, the Black Death did not create more jobs for women

by Jane Humphries, Professor of Economic History, University of Oxford
Published on 8 April 2014

The plague known as the Black Death which tore through 14th century Europe is traditionally held to have had at least one upside. Women, the theory runs, were able to exploit the labour shortages of post-plague England to find themselves in a richer and more stable position than before. However the idea that women of the era were forerunners of the post World War I generation doesn’t stand up to much scrutiny, as new research shows.

Medievalists have long debated the extent to which women shared in the “golden age” of the English peasantry that followed the demographic catastrophe of the Black Death. The plague killed between 30% and 45% of the population in its first wave 1348-59. Recurrences meant that by the 1370s England’s population had been halved.

The silver lining, for the peasantry at least, was the dramatic increase in workers’ remuneration as landowners struggled to recruit and retain labourers. The results are apparent in a rapid increase in male casual (nominal and real) wages from about 1349.


Some historians have argued that women’s gains were even more marked as they could find employment in hitherto male-dominated jobs, or migrate to towns to work in the growing textile industries and commercial services and so enjoy “economic independence”.

Others however have suggested that whatever the implications of the Black Death for male workers, the sexual division of labour prevented women from seizing the opportunities created by the labour shortage. As one account puts it: “Women tended to work in low-skilled, low-paid jobs … This was true in 1300 and it remained true in 1700”.

The debate has significant implications as optimists have gone further in arguing that women’s improved wages changed demographic behaviour by delaying marriage, promoting celibacy and reducing fertility, with the resulting so-called north-west European Marriage Pattern raising incomes and promoting further growth.
