Since the mid-nineteenth century, the average height of adult British men increased by 11 centimetres. This increase in final height reflects improvements in living standards and health, and provides insights on the growth pattern of children which has been comparatively neglected. Child growth is very sensitive to economic and social conditions: children with limited nutrition or who suffer from chronic disease, grow more slowly than healthy children. Thus, to achieve such a large increase in adult height, health conditions must have improved dramatically for children since the mid-nineteenth century.
Our paper seeks to understand how child growth changed over time as adult height was increasing. Child growth follows a typical pattern shown in Figure 1. The graph on the left shows the height by age curve for modern healthy children, and the graph on the right shows the change in height at each age (height velocity). We look at three dimensions of the growth pattern of children: the final adult height that children achieve, i.e. what historians have predominantly focused on to date; the timing (age) when the growth velocity peaks during puberty, and, finally, the overall speed of maturation which affects the velocity of growth across all ages and the length of the growing years.
Figure 1. Weights and Heights for boys who trained on HMS Indefatigable, 1860s-1990s.
To understand how growth changed over time, we collected information about 11,548 boys who were admitted to the training ship Indefatigable from the 1860s to 1990s (Figure 2). This ship was located on the River Mersey near Liverpool for much of its history and it trained boys for careers in the merchant marine and navy. Crucially, the administrators recorded the boys’ heights and weights at admission and discharge, allowing us to calculate growth velocities for each individual.
Figure 2. HMS ios能用的梯子2022
We trace the boys’ heights over time (grouping them by birth decade) and find that they grew most rapidly during the interwar period. In addition, the most novel finding was that for boys born in the nineteenth century there is little evidence that they experienced a strong pubertal growth spurt unlike healthy boys today. Their growth velocity was relatively flat across puberty. However, starting with the 1910 birth decade, boys began experiencing more rapid pubertal growth similar to the right-hand graph in Figure 1. The appearance of rapid pubertal growth is a product of two factors: an increase in the speed of maturation, which meant that boys grew more rapidly during puberty than before and, secondly, a decrease in the variation in the timing of the pubertal growth spurt, which meant that boys were experiencing their pubertal growth at more similar ages.
Figure 3. Adjusted height-velocity for boys who trained on HMS Indefatigable.
This sudden change in the growth pattern of children is a new finding that is not predicted by the historical or medical literature. In the paper, we show that this change cannot be explained by improvements in living standards on the ship and that it is robust to a number of potential alternative explanations. We argue that reductions in disease exposure and illness were likely the biggest contributing factor. Infant mortality rates, an indicator of chronic illness in childhood, declined only after 1900 in England and Wales, so a decline in illness in childhood could have mattered. In addition, although general levels of nutrition were more than adequate by the turn of the twentieth century, the introduction of free school meals and the milk-in-schools programme in the early twentieth century, likely also helped ensure that children had access to key protein and nutrients necessary for growth.

The full article from this blog is forthcoming in the Economic History Review.
By 1914, Egypt’s large agricultural sector was negatively hit by declining yields in cotton production. Egypt at the time was a textbook case of export-led development. The decline in cotton yields — the ‘cotton crisis’ — was coupled with two other constraints: land scarcity and high population density. Nonethless, Egyptian agriculture was able to overcome this crisis in the interwar period, despite unfavourable price shocks. The output stagnation between 1900 and the 1920s clearly contrasts with the following recovery (Figure 1). In this paper, we empirically examine how this happened, by focusing on the role of government investment in irrigation infrastructure, farmers crop choices (intra-cotton shifts), and access to credit.
Figure 1: Cotton output, acreage and yields, 1895-1940
The decline in yields was caused by expanded irrigation without sufficient drainage, leading to a higher water table, increased salination, and increased pest attacks on cotton (Radwan, 1974; Owen, 1968; Richards, 1982). The government introduced an extensive public works programme, to reverse soil degradation and restore production. Simultaneously, Egypt’s farmers changed the type of cotton they were cultivating, shifting from the long staple and low yielding Sakellaridis to the medium-short staple and high yielding Achmouni, which reflected income maximizing preferences (Goldberg 2004 and 2006). Another important feature of the Egyptian economy between the 1920s and 1940s, was the expansion of credit facilities and the connected increase in farmers’ accessibility to agricultural loans. The interwar years witnessed the establishment of cooperatives to facilitate small landowners’ access to inputs (Issawi,1954), and the foundation of the Crèdit Agricole in 1931, offering small loans (Eshag and Kamal, 1967). These credit institutions coexisted with a number of mortgage banks, among which the 手机怎么搭梯子到外网 was the largest, servicing predominantly large owners. Figure 2 illustrates the average annual real value of Credit Foncièr land mortgages in 1,000 Egyptian pounds (1926-1939).
Figure 2: Average annual real value of Credit Foncièr land mortgages in 1,000 Egyptian pounds (1926-1939)
Our work investigates the extent to which these factors contributed to the recovery of the raw cotton industry. Specifically: to what extent can intra-cotton shifts explain changes in total output? How did the increase in public works, mainly investment in the canal and drainage network, help boost production? And what role did differential access to credit play? To answer these questions, we construct a new dataset by exploiting official statistics (Annuaire Statistique de l’Egypte) covering 11 provinces and 17 years during 1923-1939. These data allow us to provide the first empirical estimates of Egyptian cotton output at the province level.
Access to finance and improved seeds significantly increased cotton output. The declining price premium of Sakellaridis led to a large-scale switch to Achmouni, which indicates that farmers responded to market incentives in their cultivation choices. Our study shows that cultivators’ response to market changes was fundamental in the recovery of the cotton sector. Access to credit was also a strong determinant of cotton output, especially to the benefit of large landowners. That access to credit plays a vital role in enabling the adoption of productivity-enhancing innovations is consonant with the literature on the Green Revolution, (Glaeser, 2010).
The structure of land ownership, specifically the presence of large landowners, contributed to output recovery. Thus, despite institutional innovations designed to give small farmers better access to credit, large landowners benefitted disproportionally from credit availability. This is not a surprising finding: extreme inequality of land holdings had been a central feature of the country’s agricultural system for centuries.

This article will be published in the Economic History Review and is currently available on Early View.
For a long time the plantation colonies of the Americas were seen as backward and undeveloped, dependent for their wealth on the grinding enslavement of hundreds of thousands of people. This was only part of the story, albeit a major one. Sugar, coffee, cotton, tobacco and indigo plantations were also some of the largest and most complex economic enterprises of the early industrial revolution, exceeding many textile factories in size and relying upon sophisticated technologies for the processing of raw materials. My article looks at the patent system of Jamaica and the British Atlantic which supported this system, arguing that it facilitated a process of transatlantic invention, innovation and technological diffusion.
The first key finding concerns the nature of the patent system in Jamaica. As in British America, patents were granted by colonial legislatures rather than by the Crown, and besides merely registering the proprietary right to an invention they often included further powers, to facilitate the process of licensing and diffusion. They were therefore more akin to industrial subsidies than modern patents. The corollary was that inventors had to demonstrate not just novelty but practicality and utility; in 1786, when two inventors competed to patent the same invention, the prize went to the one who provided a successful demonstration (Figure 1). As a result, the bar was higher, and only about sixty patents were passed in Jamaica between 1664 and 1857, compared to the many thousands in Britain and the United States.
Figure 1. ‘Elevation & Plan of an Improved SUGAR MILL by Edward Woollery Esq of Jamaica’
However, the second key finding is that this ‘bar’ was enough to make Jamaica one of the centres of colonial technological innovation before 1770, along with Barbados and South Carolina, which accounted for about two-thirds of the patents passed in that period. All three were successful plantation colonies, where planters earned large amounts of money and had both the incentive and the means to invest heavily in technological innovations intended to improve efficiency and profits. Patenting peaked in Jamaica between the 1760s and 1780s, as the island adapted to sudden economic change, as part of a package of measures that included opening up new lands, experimenting with new cane varieties, engaging in closer accounting, importing more slaves and developing new ways of working them harder.
A further finding of the article is that the English and Jamaican patent systems until 1852 were complementary. Inventors in Britain could purchase an English patent with a ‘colonial clause’ extending it to colonial territories, but a Jamaican patent offered them additional powers and flexibility as they brought their inventions to Jamaica and adapted it to local conditions. Inventors in Jamaica could obtain a local patent to protect their invention while they perfected it and prepared to market it in Britain. The article shows how inventors used varies strategies within the two systems to help support the process of turning their inventions into viable technologies.
Finally, the colonial patents operated alongside a system of grants, premiums and prizes operated by the Jamaican Assembly, which helped to support innovation by plugging the gaps left by the patent system. Inventors who felt that their designs were too easily pirated, or that they themselves lacked the capacity to develop them properly, could ask for a grant instead that recompensed them for the costs of invention and made the new technology widely available. Like the imperial and colonial patents, the grants were part of the strategies used to promote invention.
The article therefore argues that Jamaican patents were part of wider transatlantic system that acted to facilitate invention, innovation and technological diffusion in support of the plantation economy and slave society.

This blog is part of a series of New Researcher blogs.
A large share of the working population in developing countries is still engaged in agricultural activities. In India, for instance, over 40% of the employed population works in the agricultural sector and nearly three-quarters of the households depend on rural incomes (World Bank[1]). In addition, the agricultural sector in developing countries is plagued with low investments, forcing workers to rely on natural sources for irrigation as opposed to perennial man-made sources. Gadgil and Gadgil (2006) study the agricultural sector in India during 1951-2003 and find that despite a decline in share of agriculture in GDP in India, severe droughts still adversely impact GDP by 2-5%. In such a context, any unanticipated deviation from normal in rainfall is bound to have adverse effects on productivity and consequently, on incomes of these workers. In this paper, I study whether workers adopt migration as a coping strategy in response to income risks arising out of negative shocks to agriculture. And, if local institutions facilitate or hinder the use of this strategy. In a nutshell, the answers are yes and yes.
Using a unique dataset on annual district-level outflows of indentured migrants from colonial lndia to several British colonies in the period 1860-1912, I find that famines increased indentures. However, this effect varied according to the land-revenue collection system established by the British. Using the year the district was annexed by Britain to construct an instrument for the land revenue system (Banerjee and Iyer, 2005), I find that emigration responded less to famines in British districts where landlords collected revenue (as opposed to places where individual was responsible for revenue payments). I also find this to be the case in Princely States. However, the reasons for these results are markedly different. Qualitative evidence suggests that landlords were unlikely to grant remissions to their tenants; this increased tenant debt, preventing them from migrating. Interlinked transactions and a general fear of the landlords prevented the tenants from defaulting on their debts. Such coercion was not witnessed in areas where landlords were not the revenue collectors making it easier for people to migrate in times of distress. On the other hand, in Princely states, local rulers adopted liberal measures during famine years in order to help the population. These findings are robust to various placebo and robustness checks. The results are in line with Persaud (2024) who shows that people engaged in indentured migration to escape local price volatility.

While it plays a key role in theories of the transition to modern economic growth, there are few estimates of the quantity-quality trade-off from before the demographic transition. Using a uniquely suitable new dataset of vital records, I use two instrumental variable (IV) strategies to estimate the trade-off in Quebec between 1620 and 1850. I find that one additional child who survived past age one decreased the literacy rate (proxied by signatures) of their older siblings by 5 percentage points.
The first strategy exploits the fact that twin births, conditional on mother’s age and parity, are a random increase in family size. While twins are often used to identify the trade-off in contemporary studies, sufficiently large and reliable historical datasets containing twins are rare. I compare two families, one whose mother gave birth to twins and one whose mother gave birth to a singleton, both at the same parity and age. I then look at the probability that each older non-twin sibling signed their marriage record.
For the second strategy, I posit that aggregate, province-wide infant mortality rate during the year a younger child was born is exogenous to individual family characteristics. I compare two families, one whose mother gave birth during a year with relatively high infant mortality rate, both at the same parity and age. I then look at older siblings from both families who were born in the same year, controlling for potential time trends in literacy. As the two different IV techniques result in very similar estimates, I argue there is strong evidence of a modest trade-off.
By using two instruments, I am able to rule out one major source of potential bias. In many settings, IV estimates of the trade-off may be biased if parents reallocate resources towards (reinforcement) or away from (compensation) children with higher birth endowments. I show that both twins and children born in high mortality years have, on average, lower literacy rates than their older siblings. As one shock increases and one shock decreases family size, but both result in older siblings having relatively higher human capital, reinforcement or compensation would bias the estimates in different directions. As the estimates are very similar, I conclude there is no evidence that my estimates suffer from this bias.
Is the estimated trade-off economically significant? I compare Quebec to a society with similar culture and institutions: pre-Revolutionary rural France. Between 1628 and 1788, a woman surviving to age 40 in Quebec would expect to have 1.7 additional children surviving past age one compared to her rural French peers. The average literacy rate (again proxied by signatures) in France was about 9.5 percentage points higher than in Quebec. Assuming my estimate of the trade-off is a linear and constant effect (instead of just a local average), reducing family sizes to French levels would have increased literacy by 8.6 percentage points in the next generation, thereby eliminating most of the gap.
However, pre-Revolutionary France was hardly a human capital-rich society. Proxying for the presence of the primary educators of the period (clergy and members of religious orders) with unmarried adults, I find plausible evidence that the trade-off was steeper in boroughs and decades with greater access to education. Altogether, I interpret my results as evidence that a trade-off existed which explains some of the differences across societies.

This research is due to be presented in the third New Researcher Online Session: ‘Human Capital & Development’.
Oxford colleges were among the earliest employers in England to offer organised pension schemes for their workers. These schemes were remarkable for several reasons: they were early, the first was established in 1852; they included domestic servants, rather than white-collar workers; and colleges were unlike typical early adopters of pension schemes, which tended to be large bureaucratic organisations, such as railways or the civil service.
The schemes developed from various motives: from preventing poverty in workers’ old age to promoting middle-class values, like thrift and sobriety, through compulsory savings.
Until the Second World War, college servants were often described as a ‘labour aristocracy’, and while there were many successful senior servants, equally there were many casual, part-time and seasonal workers. The experience of these workers provides an unusually detailed look at the precarity of working-class life in the nineteenth and early twentieth centuries, and the strategies that workers developed to manage uncertainty, especially in old age.
My research uses a wide variety of archival sources, many previously unknown, from 19 Oxford colleges to consider why these colleges decided to overhaul servants’ pension provisions during this period, how retirement savings schemes were designed and implemented, and to try and understand what workers thought of these fundamental changes to the labour contract.
During this period, Oxford was a highly seasonal, low-waged economy. It was hard for many people to find enough work during the year to earn an adequate living, much less save for an old age they usually did not expect to see. Most men and women worked as long as they were capable, often past what we think of as a typical retirement age today.
It’s no surprise then that the protections against illness, disability, old age and death offered by these paternalistic employers encouraged a highly competitive labour market for college work, and the promise of an 梯子国外, or traditional non-contributory pension, was one of the most attractive features of college employment.
For centuries, colleges awarded these traditional pensions to workers. Rights to these pensions, which usually replaced about a quarter to a third of a worker’s total earnings, were insecure and awards were made entirely at the discretion of the college.
The earliest savings schemes mandated the purchase of life insurance policies. These were intended not only to protect a servant’s dependent family members, but also to limit the college’s financial liability in the event of a servant’s death. Servants were similarly risk-averse and often purchased multiple policies when they could afford to; many joined friendly societies and purchased insurance privately, in addition to employer-directed schemes.
The popularity of these schemes among Oxford colleges mirrors the growth of the insurance industry and the development of actuarial science during this period. By the 1870s, nearly all schemes included annuities or endowment assurance policies, which provided a guaranteed income for servants, usually at age 60-65, and facilitated the introduction of mandatory retirement ages for these workers.
Traditional paternalism remained influential throughout the period. Colleges insisted on controlling insurance policies, naming themselves as beneficiaries and directing the proceeds. Women, who were more likely to be in low-waged seasonal work, were nearly always excluded from these schemes and had to depend on ex gratia pension awards much longer than their male colleagues.
These early pension schemes offered no protection against inflation and colleges were usually slow to increase pension awards in response to rising prices. By the end of the Great War, dissatisfaction with inadequate pensions was one of several factors that pushed college servants to form a trade union in 1919.
To do so, I go back to the early 20th century, when futures trading in the Viennese grain market was, unlike at other trade locations at the time, such as Germany, England, or Texas, banned permanently. The 1903 parliament-enforced prohibition of futures trading was the consequence of an aversion against speculators, who were blamed for “never having held actual grain in their hands”. Putting an end to the vibrant futures market of the Agricultural Products Exchange, the city’s gathering place for farmers, millers, large-scale customers, and speculators, was thought to be the last resort to curb undue speculation. Up to the present day, futures trading has not been resumed. The uniqueness of this ban makes it an ideally suited natural experiment to test the effects of futures trading and its abolishment on spot price volatility. Prices from the Budapest Stock and Commodity Exchange, which was not affected by the ban, are used as a synthetic control. The Budapest market, as part of the Austro-Hungarian Empire, operated under similar legal-economic and geographic conditions, and was, in addition to Vienna, the only Austro-Hungarian market offering a trade in futures. This makes Budapest an ideally suited control.

With world population forecasted at 9 billion by 2050, and climate change hazards, maintaining the capacity to provide food becomes paramount for national governments, especially in developing countries. After the Second War World and the Oil Crises, food aid and trade liberalisation helped to distribute food from surplus countries to those in deficit. (Dithmer, J., & Abdulai, A. 2017).
Nonetheless, some scholars suggest that trade liberalization and agro-export specialization threaten domestic food security in developing countries (Kumar Sharma, 2016), for the following reasons: it promotes increasing dependence on food exporters, increases vulnerability when confronting volatile agrarian prices, and jeopardizes domestic production by promoting agro-exports. Moreover, the rise of agrarian trade contributes to rising consumption of fossil-fuel-based inputs like nutrients, fuel, machinery, and intensifies the use of natural resources, thereby contributing to soil erosion, greenhouse gas emissions and the loss of biodiversity. (D’Odorico et al., 2014).
Nonetheless, little is known about how the relationship between trade, food availability, and food production has evolved. This research contributes to the food security debate at the national level by introducing a historic long-rung approach and comparing the two main periods of food trade, the First and the Second Globalization in a developing context.
Figure 1. Food trade balance (1916-2016)
I analyse the long-run trend of food security in Colombia, a relevant developing country and one of the most biodiverse countries on the planet. I build on data from the early 20th century to the present, on agrarian trade, food availability, and self-sufficiency (SS) -understood as the capacity of the agrarian system to meet domestic demand.
I find that the country shifted from tropical exporter to food-dependent importer between the First and Second Globalisations. However, this change has not led to setting tropical exports aside, but to an increase in the amount of food imported from abroad. New cash crops like tropical fruits and sugar cane took the role of coffee under the FMI’s structural reforms (Figure 1). In ecological terms, this meant a change towards more intensive farming in water, land, fuel, and the use of fertilisers.
Although the import of wheat and rice served to face food shortages at the end of the 1920s and in the early 1950s, importing maize has become the rule to guarantee the availability of food during the Second Globalization. This increase in imports allowed the gains in per capita consumption but eroded the SS capacity of the domestic agrarian system to provide food. On the other side, the long-rung agro-export specialisation led to increasing the capacity to supply international markets with tropical products (Figure 2).

After its first commercial usage in 1879, Switzerland experienced a drastic increase in electricity production reflected in it having the highest per capita production in the world by 1900. During the same time period, Swiss GDP growth accelerated considerably compared with other industrialising countries (see Figure 1).
ios能用的梯子2022 Real GDP per capita in 1990US$ across leading industrial countries from 1850-1970. 1879 reflects the first commercial usage of electricity in Switzerland.
In line with this observation, the diffusion of general-purpose technologies (such as the steam engine, electricity and information technologies) is seen as a main driver of economic growth at the global level. But much less is known about the local effect of adopting these technologies. This raises the question to which extend the early adoption of electricity contributed to industrialisation and economic development in the short and long run?
My research, to be presented at the annual conference of the Economic History Society in Oxford in April 2024, answers these questions by analysing the impact of the early adoption of electricity across Switzerland on economic development through exploiting the quasi-random potential to generate electricity from waterpower.
My study finds that the adoption of electricity between 1880 and 1900 considerably increased the contemporaneous manufacturing employment share. This initial effect persists up to today with the average district observing a 1.5% higher manufacturing employment share in 2011 due to the adoption of electricity up to 1900.
This effect of early electricity adoption on employment shares in agriculture, manufacturing and services in the long run is depicted in Figure 2. Notably, the growth in manufacturing employment observed can be attributed in particular to chemical industries, which relied on access to electricity for newly developed production processes.
This effect on economic development is also observable in incomes across districts with a one standard deviation higher exposure to electricity between 1880 and 1900 leading to a 1949 Swiss Francs ($2004) higher yearly median income in 2010.

For the analysis, I newly digitised historic information on electricity production by waterpower plants across the whole of Switzerland and construct geocoded data on all potential waterpower plants that could be built as estimated by a plan of Swiss government engineers at the time.
These data are illustrated in Figure 3. Combining this information allows me to use the potential to produce electricity across districts to infer the causal impact of electricity adoption on economic development across Switzerland.
Figure 3: The map shows the exploited and potential waterpower in Switzerland in 1914. Blue-dots represent exploited waterpower, red-dots represent potential waterpower, both of existing natural sources and grey-dots represent existing and potential water-power plants that requires the building of an embankment dam. The sites are coded into 5 categories: 20-99HP, 100-999HP, 1000-4999HP, 5000-9999HP and above 10000HP.
These results provide new insight into how early access to electricity at the end of the nineteenth century helps to explain differences in economic development today. Interestingly, the long-run effect of electricity appears not to be explained by persistent differences in electricity consumption across Switzerland after the roll-out of the electricity grid in the 1920s, but rather due to increased investment into education that was complementary to the newly industries that had newly developed.

This research is due to be presented in the second New Researcher Online Session: ‘Industry, Trade & Technology’
Northern Rhodesia joined Southern Rhodesia and Nyasaland to form the Central African Federation(CAF), which lasted from 1953 to 1963 (Figure 1). During this period, two contrasting images were formed about the Federation’s economic prospects. The first depicts the exploitation of the revenue surpluses of Northern Rhodesia in favour of Southern Rhodesia, (Figure 2). The second typifies Kitwe, one of the main mining-town in the Copperbelt in Northern Rhodesia, as the most rapidly developed town in terms of industrial and commercial sectors (Figure 3). My research examines whether the Federation stimulated or undermined manufacturing growth.
Figure 1: Map of the Central African Federation, 1953-1963
This paper argues that, despite protests to the contrary, manufacturing in Northern Rhodesia grew rapidly under the Federal tariff and might be attributed to the natural protection for some industries against the high costs of transport goods from remote suppliers and to the Federal tariff against South Africa imports.

My research offers new insights into the rapid growth of the market in Northern Rhodesia. Specifically, to what extent did local industry respond to the mining-led economic expansion in Northern Rhodesia. The first census of industrial production occurred in 1947, which provides a benchmark against which to measure growth rates before and during the Federal tariff system. Industrial production in Northern and Southern Rhodesia grew from 3.3 percent to 6 percent, and from 12 percent to 16.3 percent, respectively, between 1954 and 1963. The net value added of manufacturing in Northern Rhodesia grew from less than £1 million in 1947 to £6.40 million in 1955, then it reached £12.68 million in 1963. Southern Rhodesia witnessed a significant increase in the net value added of manufacturing, from £20 million in 1953 to £50.2 million in 1963.
The composition of manufacturing output before and during the Federation reveals that rapid growth in Northern Rhodesia’s production of food, drinks, textiles, and chemicals — which constituted the majority of domestically manufactured goods (Table 2).

My research suggests a more nuanced interpretation is required of the importance of Northern Rhodesia to the South. The Federation curbed Northern Rhodesia’s development of specific industries that existed in Southern Rhodesia, especially steel and textiles, thereby disrupting the optimum allocation resources to industrial production in the South.
However, Northern Rhodesia’s net value added of manufacturing output benefited from the application of Federal tariffs in certain consumer industries that grew rapidly, such as processed foods and drinks. Consequently, the Federation was beneficial to the growth of manufacturing in Northern Rhodesia (Zambia).
