Fudan University Lecture 3 1

The Role of Agriculture in Economic Growth

• Standard belief was that growth of agricultural productivity was a prerequisite for industrialization. This had three effects:

1. Released labor and other factors of production to be used in manufacturing.

2. Provided a market for industrial and other non-agricultural goods.

3. Provided Manufacturing with cheap raw materials and fuel.

Fudan University Lecture 3 2

The problem is that this is true for a closed economy

• In an open economy, it works differently:

• High agricultural productivity signals to the economy that this is its comparative advantage, and it might specialize in it.

• However, if the rate of technological progress in manufacturing is higher, this could be a “correct” but very costly decision since the economy might get “locked into” a bad equilibrium.

Fudan University Lecture 3 3

Agriculture and the Industrial Revolution

• What role did agricultural innovation play in the economic modernization of Britain?

• The paradox is, that Britain was very efficient in producing agricultural goods, yet it did not have a comparative advantage in it, and thus after 1870 it increasingly abandoned it.

• Britain fed with a little help a population that grew by a factor of 2.5 between 1750 and 1850.

Fudan University Lecture 3 4

Controversy:

• Was there an “agricultural revolution” that occurred side-by-side with the Industrial Revolution?

• Some scholars still insist that there was one, most others have come to deny it.

• Why is this so hard to decide?

Page 5: Fudan University Lecture 31 The Role of Agriculture in Economic Growth Standard belief was that growth of agricultural productivity was a prerequisite.

Fudan University Lecture 3 5

One problem is the lack of data

• We do not really know how much was either produced or consumed, since few farm products were taxed or paid a tariff (which is where most information comes from)

• We have data from some farms that kept good accounts that survived, but the problem is that these may not have been representative.

• To make things more confused, Britain imports agricultural goods from Ireland, but the Union of 1800 meant that after 1830 there are no more trade statistics.

Page 6: Fudan University Lecture 31 The Role of Agriculture in Economic Growth Standard belief was that growth of agricultural productivity was a prerequisite.

Fudan University Lecture 3 6

• One interesting thing to examine is the effect of the Enlightenment on agriculture, or the “agricultural enlightenment.”

Page 7: Fudan University Lecture 31 The Role of Agriculture in Economic Growth Standard belief was that growth of agricultural productivity was a prerequisite.

Fudan University Lecture 3 7

In some ways the attempt to improve farming symbolizes the essence of the movement: the belief in the ability of

knowledge to bring about progress

In the eighteenth century there is a lot of activity trying to improve agriculture through systematic Enlightenment kind of activities: meetings and associations; publications; prizes and awards. French refer to this as agromanie.

Some of which were well-known like the Honourable Society of Improvers in the Knowledge of Agriculture in Scotland in Edinburgh in 1723. A lot of good will, but its members were intellectuals, politicians, and local nobility.

During the eighteenth century many such societies were founded in Scotland and England, as well as informal gatherings such as the annual ceremonial sheep-shearing

hosted by Coke of Holkham.

Page 8: Fudan University Lecture 31 The Role of Agriculture in Economic Growth Standard belief was that growth of agricultural productivity was a prerequisite.

Fudan University Lecture 3 8

A large number of publications, both books and periodicals on farming appeared

• Many of these tried to spread agricultural knowledge and techniques.

• William Ellis’s Modern Husbandman or Practice of Farming (8 vols.) first published in 1731 gave a month-by-month set of suggestions, much like Arthur Young’s most successful book, The Farmer’s Kalendar (1770).

• Many of the leading scientists such as the geologist James Hutton, the physician-botanist Erasmus Darwin, the physicist Archibald Cochrane, and the chemist Humphry Davy wrote books on agriculture.

Page 9: Fudan University Lecture 31 The Role of Agriculture in Economic Growth Standard belief was that growth of agricultural productivity was a prerequisite.

Fudan University Lecture 3 9

Some of these were professionals

Most famous, of course, Arthur Young, his nemesis William Marshall, and John Sinclair (President of the Board of Agriculture, f. 1793).

But many others. Here is a man named David Henry:

Fudan University Lecture 3 12

Much like the medical enlightenment, the agricultural enlightenment did not yield much in the eighteenth century

• Voltaire in his famed Philosophical Dictionary (1816, Vol. 3, p. 91) caustically remarked that after 1750 many useful books on agriculture were read by everyone but the farmers.

• Charles Gillispie (1980, p. 367) concluded that the impact of information flows “beyond the circle of persons who wrote, printed, and read the books,” was probably small.”

• Most important: most scholars looking for large and dramatic improvements in British agriculture at the time cannot find it.

Page 13: Fudan University Lecture 31 The Role of Agriculture in Economic Growth Standard belief was that growth of agricultural productivity was a prerequisite.

Fudan University Lecture 3 13

Bottom line on agricultural enlightenment:

Some successes (e.g. in selective breeding and improved tools).

But on the whole the entire project was disappointing, at least before the 1840s.

Page 14: Fudan University Lecture 31 The Role of Agriculture in Economic Growth Standard belief was that growth of agricultural productivity was a prerequisite.

Fudan University Lecture 3 14

Contemporaries were aware of this:

“Agriculture, though it depends very much on the powers of machinery, yet I'll venture to affirm, that it has a greater dependence on chemistry. Without a knowledge in the latter science, its principles can never be settled”

(Lord Kames, The Gentleman Farmer, 1776, p. 5).

Page 15: Fudan University Lecture 31 The Role of Agriculture in Economic Growth Standard belief was that growth of agricultural productivity was a prerequisite.

Fudan University Lecture 3 15

What seems to be clear:• British agriculture was quite productive by the standards

of the time. Recent estimates find that output per worker around 1750 was 4.3 times that of France, and output per acre 2.5 times higher. But that could have many reasons: more capital, better quality soil, better workers, or superior organization.

• One mechanism that worked for British farming (much like that in the Low Countries) was a synergy between “arable” and “husbandry” --- that is, products of the land and those of animals. Much of European agriculture depended on this interaction, but in Britain between 1700 and 1850 it was brought to perfection, a system known as “high farming.”

Page 16: Fudan University Lecture 31 The Role of Agriculture in Economic Growth Standard belief was that growth of agricultural productivity was a prerequisite.

Fudan University Lecture 3 16

European Agriculture:Synergy between arable and husbandry

• Animals helped arable:• Through haulage (both on the field and in transport).

• Producing manure as fertilizer

• Generated cash from meat, dairy products, wool, leather.

• Arable helped husbandry:• By letting animals graze on the stubble after harvest

• By letting animals graze on fallow lands.

• By producing fodder crops, esp. after 1700. Turnips, clover, Mangel-wurzels, hay.

Page 17: Fudan University Lecture 31 The Role of Agriculture in Economic Growth Standard belief was that growth of agricultural productivity was a prerequisite.

Fudan University Lecture 3 17

The other element was crop rotations

• Why rotate?

• Growing the same crops on the same plots exhausts the soil from nutrients (primarily nitrogen).

• It also causes diseases and pests; alternating crops helps to get rid of them.

• Fallowing used to “rest” the land (restore some minerals and break pest-cycles), used for grazing but it does not grow a crop, so good rotations are land-augmenting innovations.

Page 18: Fudan University Lecture 31 The Role of Agriculture in Economic Growth Standard belief was that growth of agricultural productivity was a prerequisite.

Fudan University Lecture 3 18

Other important technological changes:

• Better tools and implements, • Especially plows e.g. the Rotherham plow, which had a blade of

steel and was much lighter and stronger.

• Better threshing machines first developed in 1784 (run on steam after 1825).

• Seed-drill (Jethro Tull)

• Larger, stronger, and healthier animals through selective breeding (Robert Bakewell).

Page 22: Fudan University Lecture 31 The Role of Agriculture in Economic Growth Standard belief was that growth of agricultural productivity was a prerequisite.

Fudan University Lecture 3 22

Yet progress in productivity was slow

• One reason is that agricultural technology is not like manufacturing: it needs local “tweaking” and adaptation to specific microclimates and topographical conditions.

• Another is that competition between farmers is not so tight that each farmer must adopt best-practice techniques or disappear. There is enormous variation in the level of efficiency across Britain, even among adjacent farms.

Page 23: Fudan University Lecture 31 The Role of Agriculture in Economic Growth Standard belief was that growth of agricultural productivity was a prerequisite.

Fudan University Lecture 3 23

• Clearly Britain was able to feed a much larger population in 1850 than it did in 1700, so where did this food come from?

• One factor, not stressed enough, is that it added many acres to land under cultivation, by converting some pasture to arable, and by cultivating previous un- or undercultivated “wastelands.” Moreover it accumulated farm capital and the quality of capital improved (larger sheep and cows).

• That means that land was not a “fixed” factor, so the dangers of diminishing returns are overestimated. Yet the new lands were marginal, so productivity gains would be limited.

Fudan University Lecture 3 27

What the data show:

• Until 1800 or so, British agriculture kept more or less pace with rapid population growth.

• After that it fell behind a bit, and imported more and more food, esp. from Ireland and the Baltic areas.

• Britain achieved its agricultural growth without an agricultural revolution, without a risky dependence on a single high-yield crop (e.g. Irish potatoes), without increasing the number of people working on the land, and without spectacular macroinventions that turned production upside-down (such as nitrate-fixing).

Page 28: Fudan University Lecture 31 The Role of Agriculture in Economic Growth Standard belief was that growth of agricultural productivity was a prerequisite.

Fudan University Lecture 3 28

• What was critical was organization and farm-size: British farms got bigger and gradually turned to be capitalist enterprises. Widely believed: there were economies of scale in management.

• By 1800 most of British agriculture is run in relatively large units (over 100 acres) that were owned by a landlord, often absentee. This is classical capitalist agriculture: the landlord hired a “farmer” or capitalist entrepreneur, who rented the farm from him and managed it, hired laborers, and owned or rented the equipment and livestock needed to run the farm, made all the decisions, paid the workers and the rents and kept the rest as profits.

• Labor came primarily from a landless or semi-landless rural “proletariat.” But was this necessarily bad?

Page 29: Fudan University Lecture 31 The Role of Agriculture in Economic Growth Standard belief was that growth of agricultural productivity was a prerequisite.

Fudan University Lecture 3 29

What happened to small owner-proprietors (yeomen)

• Part of the answer is that they vanished due to the enclosures.

• What were the enclosures?

• They were the elimination of “open field agriculture.”

• To understand open fields we must first understand traditional property rights in open-field agriculture.

Page 30: Fudan University Lecture 31 The Role of Agriculture in Economic Growth Standard belief was that growth of agricultural productivity was a prerequisite.

Fudan University Lecture 3 30

Traditionally, the lord “owned” the land

• But the tenants in the common law that ruled Britain had many rights that were traditional and that could not be taken away. For instance, “copyholders” held land more or less in perpetuity even if they owned rent and other services. Freeholders paid a rent but basically had perpetual rights.

• So consider a village owned by a lord, what would it look like?

Fudan University Lecture 3 32

• So what does farmer j subsist on?

1. He grows field crops on the rectangles he owns (if they are not fallowed)

2. He gets some vegetables and pulses from his small garden3. He gets the right to use the commons and waste, to graze his

animals and collect other valuables (timber, fish).4. He has the right to graze his cattle on the fields of farmer k

(and all other fields) after the harvest is in.5. He gets the right to graze his cattle on all of a field if it is

fallowed that year.

Page 33: Fudan University Lecture 31 The Role of Agriculture in Economic Growth Standard belief was that growth of agricultural productivity was a prerequisite.

Fudan University Lecture 3 33

Open fields were thought to have been inefficient

• The system was reputed to be inefficient since coordination was difficult to achieve and it maximized “neighborhood effects.”

• The commons was supposed to be overgrazed and overexploited because no one owned it (“tragedy of the commons”).

• It was also said to be an obstacle in the way of technological change because the entire village had to cooperate if new crops or rotations were introduced.

Page 34: Fudan University Lecture 31 The Role of Agriculture in Economic Growth Standard belief was that growth of agricultural productivity was a prerequisite.

Fudan University Lecture 3 34

Modern research has shed new light on this

• In recent years economic historians have come to doubt this, and shown that open field agriculture was more flexible and capable of improvement than had hitherto been believed. Commons were “managed” and not as overgrazed as was once believed.

• All the same, open fields had basically disappeared by 1820 through enclosures.

• Why were there enclosures, and how did they work?

Page 35: Fudan University Lecture 31 The Role of Agriculture in Economic Growth Standard belief was that growth of agricultural productivity was a prerequisite.

Fudan University Lecture 3 35

Voluntary enclosure

• In most cases, the landlord takes the initiative.

• If a supermajority of tenants agrees, the village can enclose on its own. They then consolidate the holdings so that each farmer gets one contiguous field that he then has to enclose (by fences or hedges). The commons and wastes are largely eliminated and divvied up between the tenants or taken by the landlord. Rights of grazing on fields not directly owned are eliminated.

• If no majority can be achieved, voluntary enclosure cannot be attained, so need a third party.

Page 36: Fudan University Lecture 31 The Role of Agriculture in Economic Growth Standard belief was that growth of agricultural productivity was a prerequisite.

Fudan University Lecture 3 36

This produced Parliamentary enclosures.

• Landlords could petition Parliament to enclose the land. If granted, professional surveyors and attorneys decided on how to divide up the village, along the same line as above. All rental contracts were rewritten.

• After 1750, over 1,800 such bills were passed to enclose the 30% of British land that had resisted enclosures.

• The procedure clearly discriminated against smallholders.

Page 37: Fudan University Lecture 31 The Role of Agriculture in Economic Growth Standard belief was that growth of agricultural productivity was a prerequisite.

Fudan University Lecture 3 37

Why?

• Smallholders were less likely to have documented rights and could not afford lawyers.

• They are the ones that depended most on wastes and commons.

• Since fencing in one’s land was mandatory, the costs per acre fell in larger plots (since the costs of a square piece of land are 4cn/n2 = 4c/n), where c is the unit cost of fencing.

Page 38: Fudan University Lecture 31 The Role of Agriculture in Economic Growth Standard belief was that growth of agricultural productivity was a prerequisite.

Fudan University Lecture 3 38

As a result, a large number of smallholders lost their land.

• Many of those became a landless proletariat, who worked for wages on others’s farms.

• What complicated the matter was the disappearance of cottage industries where men and women produced manuf. goods in the offseason.

• How can we model this?

Page 39: Fudan University Lecture 31 The Role of Agriculture in Economic Growth Standard belief was that growth of agricultural productivity was a prerequisite.

Fudan University Lecture 3 39

Consider an individual peasant

• There are two seasons, H (“high”) and L (“low) of equal length. In both of them he faces a small piece of land that is responsible for diminishing returns to labor.

• There is another activity, call it “Z” in which the family can make a manufactured good, but because it uses only labor (by assumption), there are no diminishing returns.

• The family then decides to allocate its labor between agricultural work and Z-production.

• The result is a “kinked” demand for labor curve.

Fudan University Lecture 3 41

• In this world, the peasant will work in the Low season the distance FEL in Z-production, whereas in the High season he will specialize in agriculture (when he earns G)

• The rise of the competition of mechanized industry means that the price of Z falls (if Z and the good that is mechanized are substitutes, which they not always were).

• If the price of Z falls below a certain level, it will disappear altogether. By 1850, this is more or less what happened.

Page 42: Fudan University Lecture 31 The Role of Agriculture in Economic Growth Standard belief was that growth of agricultural productivity was a prerequisite.

Fudan University Lecture 3 42

• This, too, contributed to the disappearance of British agriculture, because for many rural worker being able to “moonlight” in the off-season in cottage industries made it worth their while to stay in rural areas. Once this was no longer available, they had no reason to stay in the countryside.

• Another factor was the Poor Law, which subsidized them in the off-season if nothing else was available, but was abolished in 1834.

• As a result, people migrate --- either to the cities and after 1845, increasingly to North America.

Page 43: Fudan University Lecture 31 The Role of Agriculture in Economic Growth Standard belief was that growth of agricultural productivity was a prerequisite.

Fudan University Lecture 3 43

The “service sector”• Something of an anachronism.

• Basically includes everything that is not in manufacturing or agriculture. Not sure that makes fully sense in this economy since a lot of people sold what they made or grew.

• The British economy during the Industrial Revolution is a reasonably sophisticated economy, with a large retail sector, extensive transportation, financial services, as well as personal services such as doctors, lawyers, surgeons.

Page 44: Fudan University Lecture 31 The Role of Agriculture in Economic Growth Standard belief was that growth of agricultural productivity was a prerequisite.

Fudan University Lecture 3 44

The importance of transportation costs

• The gains from trade are limited by “trading costs”.

• Trading costs consist of three basic elements:

• Physical transport costs

• Artificial costs such as tariffs and tolls

• Frictional costs such as lack of information, contract enforcement, insurance, and such.

Page 45: Fudan University Lecture 31 The Role of Agriculture in Economic Growth Standard belief was that growth of agricultural productivity was a prerequisite.

Fudan University Lecture 3 45

• In many of these respects, Britain was very fortunately situated:

• No internal tariffs within England and after 1707 not with Scotland either. Ireland only fully joins in in 1830.

• It has good ports and the best facilities for coastal shipping in Europe.

• A few decent navigable rivers, but not as good as Germany.

Page 46: Fudan University Lecture 31 The Role of Agriculture in Economic Growth Standard belief was that growth of agricultural productivity was a prerequisite.

Fudan University Lecture 3 46

Transportation economics is unusual

• Often regarded as at the boundary between the private sector and the public sector. In most modes, the private and the public sector seem to bounce ownership and control back and forth. Thus airlines are regulated and deregulated, highways are built by the public sectors but tolls farmed out, railroads are built by private sector entrepreneurs, then nationalized and then privatized back again

• In this “grey area” Britain between 1700-1850 took an extreme position: private initiative was predominant and government played a passive and secondary role. Different from other European nations.

Page 47: Fudan University Lecture 31 The Role of Agriculture in Economic Growth Standard belief was that growth of agricultural productivity was a prerequisite.

Fudan University Lecture 3 47

Consider road-building• Traditionally had been the responsibility of local authorities, but that created classic

free rider problem (“race to the bottom”).

• After 1750, private roads are being built everywhere, known as “turnpikes”. These had to be established by Parliament but when they were, they were entitled to levy tolls and thus pay for themselves.

• By 1830, 22,000 miles of road had been turnpiked (about 17 percent of the total roads, but included the most important roads).

• These roads were much improved and provided significantly faster transport. Average speed on roads increased from about 4 m/ph to 8 mph between 1700 and 1830.

• Before the railroad, stage-coaching provided a reasonably comfortable and reliable means of travelling for those who could afford it.

Fudan University Lecture 3 48

Three famous names of the road transportation revolution:

John Metcalfe (1717-1810)

John Loudon McAdam (1756-1836)

Thomas Telford (1757-1834).

Fudan University Lecture 3 49

Two Examples:

• In 1754 the trip from London to Manchester was done in 4 days, in 1784, it could be done in two days.

• The longer trip from London to Edinburgh took 12 days in winter and 10 days in summer; in 1836 it could be done in 45 ½ hours.

Page 50: Fudan University Lecture 31 The Role of Agriculture in Economic Growth Standard belief was that growth of agricultural productivity was a prerequisite.

Fudan University Lecture 3 50

What contributed to the improvement of road transport?

• Better designed and lighter carriages (but still a long shot away from modern pneumatic tires and asphalt roads).

• Better built roads: better drained, longer-lasting, less exertion on horses.

• Better organization (more competition, more effective horse-relays)

• Better and larger bridges: some magnificent achievements of British engineers.

Fudan University Lecture 3 52

A similar effort took place with canals

• Canal age preceded the railways. In some sense this was an inefficient investment because its effective life was cut short by the unanticipated emergence of trains in the 1830s.

• Not very glamorous: bulky goods, mostly short trips.

• Like turnpikes, they were built by private entrepreneurs, after obtaining Parliamentary approval.

Page 53: Fudan University Lecture 31 The Role of Agriculture in Economic Growth Standard belief was that growth of agricultural productivity was a prerequisite.

Fudan University Lecture 3 53

• Bridgewater canal: initiated by the Duke of Bridgewater who owned coal mines in Worsley and wanted to transport the coal cheaper to its customers in Manchester. It had an aqueduct and 10 locks and built by the brilliant engineer James Brindley, one of the towering geniuses of engineering in the early Industrial Revolution. Originally about 7 miles long, but soon extended to about 14 and widely regarded the first of the “canal mania”.

Fudan University Lecture 3 55

• A large network of canals were built between 1770 and 1820, coinciding with the Industrial Revolution.

• One example: Leeds-Liverpool Canal.

• Commenced in 1770, extended to 127 miles across the Pennines.

• Canal has 91 locks plus a 1630 ft long tunnel. Yet it cut transport cost from Leeds to Liverpool by 80%.

Fudan University Lecture 3 58

Shipping

• Took two forms: coastal and long-distance ocean shipping (canal barges are a different technique).

• Major breakthroughs in shipping are limited. Little radical change in ship design before 1815.

• But advances in navigation technology (marine chronometer).

Fudan University Lecture 3 61

Ship design:

• After 1820 things change. First, wooden sailing ships improve as the rigging becomes more sophisticated (“clipper ships”).

Page 62: Fudan University Lecture 31 The Role of Agriculture in Economic Growth Standard belief was that growth of agricultural productivity was a prerequisite.

Fudan University Lecture 3 62

With the decline in the price of iron, people get interested in iron ships.

• These ships were more rigid and had stronger structure, although other problems emerged that required further development.

• First attempts in the 1780s, but slow progress. By the middle of the nineteenth century most of the hulk is made of iron. After Bessemer and the appearance of cheap steel, ships are made of steel.

Page 63: Fudan University Lecture 31 The Role of Agriculture in Economic Growth Standard belief was that growth of agricultural productivity was a prerequisite.

That led to creations such as this:

• “Great Eastern”, largest ship built in the nineteenth century, 32,000 tons, room for 4,000 passengers. Still was hybrid, with six masts.

• Improvements in ship engine design and cooling (had special need, because supply of fresh water on board is limited). This led to the surface condenser, which separated the water that cooled the condenser and the water in it, was developed in the 1830s and came into general use in about 1850.

• McNaught’s compound marine steam engine.

In the compound engine, high pressure steam from the boiler expands in a high pressure (HP) cylinder and then enters one or more subsequent lower pressure (LP) cylinders. The complete expansion of the steam now occurs across multiple cylinders and as less expansion now occurs in each cylinder so less heat is lost by the steam in each. This reduces the magnitude of cylinder heating and cooling, increasing the efficiency of the engine.

• Or the slow development of the screw propellor.

[one telling example: in 1837 a British engineer, Francis Pettit Smith launched a steam ship with a screw-propellor made out of wood; in one of the trials half of it broke off. It was noted with amazement that this accident actually increased the speed of the vessel.]

Railroads

• Not really an “invention” but a recombination of existing techniques, above all High Pressure steam Engine and the idea of rails, plus scores of other technical issues dealing with coupling, braking, power transmission, etc.

• Not really feasible until work on High Pressure engines had started.

• Between 1805 and 1830, scores of British engineers and mechanics work on the problem of applying steam to cheap land transport --- not clear what form it would take.

Page 72: Fudan University Lecture 31 The Role of Agriculture in Economic Growth Standard belief was that growth of agricultural productivity was a prerequisite.

Fudan University Lecture 3 72

First “real railroad”

• Stockton & Darlington, 1825 (but in part pulled by horses).

• After the famed “rainhill” competition, won clearly by the design proposed by George and Robert Stephenson, railroads “take off”

• In 1830 Britain has 200 km of railroad track, most of it pulled by horses. In 1850 it has 9800 km, in 1900 30,000.

Fudan University Lecture 3 75

Railroads: while the technology was not “revolutionary”, the economic impact was.

• Huge capital investment in tracks, rolling stocks, and stations. At its peak, absorbed more than half the annual capital formation of the country. Requires institutional innovations in capital markets, leading to boom 1844-46, and crash of 1847.

• Network externalities. Need to coordinate between different railroad companies (railroad gauge, schedules). Concerns about safety.

• Enhanced labor mobility, both SR and LR. Higher degree of competitiveness.

Fudan University Lecture 3 76

Railroad Linkages

• “Backward Linkages.” Effects on industries that supplied railroad with intermediate goods, such as engines, machinery, coaches, iron, timber, construction materials. If there were learning effects or economies of scale, the railroad helped to realize them. If not, however, this a cost, not a benefit.

• Forward linkages: the positive effect that a decline in transport cost has on the economy, which includes 1) direct effect on consumers through cheaper transport costs of people and goods and 2) indirect effects on specialization and the geographical division of labor.

Forward linkages

• Since Fogel (1964), scholars have tried to estimate the “net social savings” of railroads, that is, how much would it have cost society to ship the volumes of goods with the railroads using the next best mode?

• Fogel attack on the “indispensability axiom.”

• The idea of social savings is quite simple: what is the value of a new product? This can only be assessed in relation with the previous technology.

Page 80: Fudan University Lecture 31 The Role of Agriculture in Economic Growth Standard belief was that growth of agricultural productivity was a prerequisite.

Page 81: Fudan University Lecture 31 The Role of Agriculture in Economic Growth Standard belief was that growth of agricultural productivity was a prerequisite.

Fudan University Lecture 3 81

• So the social savings are the “red trapezoid” which requires us to know the shape of the demand curve, and the difference in costs of the “old” and the “new”.

• To actually calculate this, one needs to make many assumptions, since the actual demand curve is not observed. So estimate the entire red rectangle which is larger than the trapezoid we want to measure. So we get an overestimate. If it’s still true that it’s not very large, than social savings are limited.

• But: Railroads were not only cheaper but also more dependable, faster etc. Is all that accounted for?

• It turns out that it’s easier to compute this for freight than for passengers, since for the latter comfort and speed may have been more important. Overall, the estimates show that freight social savings were about 4% of GDP in 1860, while passengers might have added 2-6% depending on the assumptions one makes about the costs of earlier techniques.

Page 82: Fudan University Lecture 31 The Role of Agriculture in Economic Growth Standard belief was that growth of agricultural productivity was a prerequisite.

Fudan University Lecture 3 82

This does not mean that railroad were not important:

• Direct cost-saving effects may have been relatively small.

• But it made the economy more competitive because trains connected markets with one another. It also allowed more regional specialization and just fostered “gains from trade” effects.

• It increased the mobility of labor and thus increased the efficiency of the allocation of resources and reduced seasonal unemployment.

• It made central control by government more effective (not so important in Britain, but very important in countries like Russia)

• It brought technological progress and a sense of dynamism to many places where previously little had happened. By 1840, steam was everywhere.

Page 83: Fudan University Lecture 31 The Role of Agriculture in Economic Growth Standard belief was that growth of agricultural productivity was a prerequisite.

Fudan University Lecture 3 83

In addition to railroads, there was the telegraph

• Much smaller in its impact, but in some senses a more impressive innovation.

• Information flowed much faster than under previous systems.

• Depended much more on scientific breakthroughs (Hans Oersted, 1819, and the further experiments of Andre-Marie Ampère showed that electrical current could affect a magnetic needle).

• The research that led to the telegraph was truly international (unlike the railroad which was largely British). Joseph Henry, an American has been claimed to be the true inventor.

Fudan University Lecture 3 86

• In 1831 Henry built and successfully operated, over a distance of one mile (1.6 kilometres), a telegraph of his own design.

• The only claim that Samuel Morse has to be the inventor was the invention of the eponymous Morse Code (one of many codes proposed) --- and even that was due to his partner Alfred Vail. Still, in the US his patent was upheld so he became rich and famous.

Page 87: Fudan University Lecture 31 The Role of Agriculture in Economic Growth Standard belief was that growth of agricultural productivity was a prerequisite.

Fudan University Lecture 3 87

• All the same, the first successful telegraph company was established by two Brits, Charles Wheatstone and William Cooke.

• This couple is a classic “pairing” of a learned scientist and a hyperactive entrepreneur. Cooke was the enthusiastic entrepreneur but had no scientific knowledge; Wheatstone as a trained scientist knew about Henry’s work and was the brain behind the project.

• Took a while before people got used to the idea. But in 1844 the Queen had a baby boy and the news was transmitted to London by telegraph. Then two criminals fleeing by train were apprehended by information traveling by telegraph.

• Cooke founded the Electr. Telegraph Co. with a financier named John Lewis Ricardo which bought their patent rights and by 1852 had laid 4000 miles of cable.

Fudan University Lecture 3 90

But the technique was far from perfect and required many microinventions

• The main problem turned out to be wear and tear of cables due to inadequate insulation. Of the 18,000 km laid before 1861, only 4,800 were operational that year; the famous transatlantic cable of 1858 ceased working after a 3 months.

• Other problems had to do with the physics of electric impulses. They were large solved by this man:

Fudan University Lecture 3 92

In the next two decades people tried to use this for long-distance communications

• First successful cables laid in 1837 (Cooke & Wheatstone) but system takes off only in the 1840s.

• Complementary with railroads, but also considerable impact on the speed and efficiency with which markets worked.

• In terms of innovation: more radical than most, typical macroinvention, compared with previous technologies (e.g., battle of New Orleans).

Page 93: Fudan University Lecture 31 The Role of Agriculture in Economic Growth Standard belief was that growth of agricultural productivity was a prerequisite.

Fudan University Lecture 3 93

The Financial Sector

• Not very large in terms of employment or value added but very important as “lubricant.”

• Worked quite differently from our own time. There was a stock exchange but it bought and sold mostly government securities and bonds issued by commercial enterprises such as the East India Company, or debt issued by canals, turnpikes, and other public ventures.

Page 94: Fudan University Lecture 31 The Role of Agriculture in Economic Growth Standard belief was that growth of agricultural productivity was a prerequisite.

Fudan University Lecture 3 94

The Stock Exchange

• Started in the late 17th century in the famous coffee houses off Lombard Street.

• In 1773 they moved into a specific building and after 1801 only “members” could trade.

• But the new manufacturing firms that sprung up during the Industrial Revolution did not have access to the stock market. Even after the Bubble Act was repealed (1825) they made no use of it.

Page 95: Fudan University Lecture 31 The Role of Agriculture in Economic Growth Standard belief was that growth of agricultural productivity was a prerequisite.

Fudan University Lecture 3 95

Stock market was trading in limited securities

• Shares and bonds of some utilities (canals etc.), Bank of England and East India Company shares, and various government securities.

Page 96: Fudan University Lecture 31 The Role of Agriculture in Economic Growth Standard belief was that growth of agricultural productivity was a prerequisite.

Fudan University Lecture 3 96

Banking in Britain, 1700-1900

• Most prominent bank is the BoE, f. 1694.

• Typical product of the age of mercantilism and rent-seeking. It was a private institution. The only joint-stock bank in Britain [until 1826], and after 1720 dominated public finances through being the sole fiscal agent of the Crown, lending it money and placing its securities.

• It was a private bank, and as such issued notes that circulated as means of payment.

Page 97: Fudan University Lecture 31 The Role of Agriculture in Economic Growth Standard belief was that growth of agricultural productivity was a prerequisite.

Fudan University Lecture 3 97

Slowly, over time, it morphed into a central bank

• It received a monopoly on issuing bank notes (after 1844) that circulated as cash.

• These notes were declared “legal tender.”

• Bank charter act of 1844, provided some indication that the B of E was a “public institution”: it was ordered to separate its note-issuing business from the rest, and expected to keep an eye on the Money Supply and prevent it from over-expanding (as feared by the “currency school.”).

• Some elements of its function as a lender of last resort emerge in 1825 and again in 1844. But little power to carry out “monetary policy.”

Page 98: Fudan University Lecture 31 The Role of Agriculture in Economic Growth Standard belief was that growth of agricultural productivity was a prerequisite.

Fudan University Lecture 3 98

Other Banks beside the B of E• Private London “Merchant” Banks (descending from the goldsmiths of London)

family operated, not joint-stock), basically took deposits and made loans. Often founded by emigrants (Baring, Rothschild). Were “correspondent banks” for country banks.

• Country Banks --- replaced notaries and attorneys as intermediaries. Grew from almost none in 1750 to 800 in 1815 and 1100 in 1838. Lent to people they knew to two degrees of separation. Mostly small affairs, but critical in discounting bills of exchange.

• They could issue notes, provided they had six partners or fewer. This was important because of the need for low-denomination bills.

• Could not incorporate before 1826 (and even then only if they were more than 65 miles from London).

• These rules were mostly passed at the pressure of the B of E. These Banks were very vulnerable and many of them failed during “panics.”

Page 99: Fudan University Lecture 31 The Role of Agriculture in Economic Growth Standard belief was that growth of agricultural productivity was a prerequisite.

Fudan University Lecture 3 99

How important was the Banking system for economic development?

• People who study banks like to think they were essential.

• But in this age, they were only one means to attain the most important thing: credit. There were many other sources.

• L-T Capital accumulation: mostly from re-invested profits, circumvents formal credit market altogether.

• S-T loans: “inland” bills of exchange or letters of credit.

Page 100: Fudan University Lecture 31 The Role of Agriculture in Economic Growth Standard belief was that growth of agricultural productivity was a prerequisite.

Fudan University Lecture 3 100

Financial Sector also includes insurance

• Maritime Insurance important in a seafaring nation.

• Started in a coffeehouse owned by Thomas Lloyd, who moved to Lombard St. in 1692. Competitive industry of many small underwriters, quite well organized.

• Moves to the Royal Exchange in 1774.

• Lloyd’s of London, an umbrella association of small and unincorporated underwriters, sets the rules for others.

Fudan University Lecture 3 101

Fire and Life Insurance

• Volume of Fire insurance grows rapidly, but the risks grew even faster with urbanization, since many of the early urban dwellings were built from wood.

• Life insurance also grew, but not clear if people became more prudent or whether this was a lugubrious form of gambling. Needed sophisticate mathematicians to compute actuarial values of life-insurance policies, affected by changes in mortality. Such people actually did this work, e.g. Richard Price and Benjamin Gompertz.

Page 102: Fudan University Lecture 31 The Role of Agriculture in Economic Growth Standard belief was that growth of agricultural productivity was a prerequisite.

Fudan University Lecture 3 102

Retail sector

• “England is a Nation of shopkeepers” --- Adam Smith.

• Occupational specialization meant that people depended on exchange, that is buying things from stores.

• Sharp increase in that due to the “Industrious Revolution” as well as growing consumption of imported goods. Growing popularity of off-the-rack clothing, sold in specialty stores.

Page 103: Fudan University Lecture 31 The Role of Agriculture in Economic Growth Standard belief was that growth of agricultural productivity was a prerequisite.

Fudan University Lecture 3 103

• Many artisans were also “retail outlets” in 1700, but by 1850 much of that has become specialized. Still, bakers, shoemakers, tailors etc. were clearly in both categories.

• In the 1841 census, over 16 percent of employed males older than 20 declared occupations such as “grocer,” “dealer,” and “broker.” [For women much lower, but that figure is clearly biased].

• With urbanization, increasing trade between “strangers” so consumer less and less protected by reputation and “caveat emptor” rules.

• Number of shopkeepers in 1688 about 9.6% of all households, in 1841 perhaps 16%, numbers are hard hard to compare but they indicate a deepening of commercialization.

Page 104: Fudan University Lecture 31 The Role of Agriculture in Economic Growth Standard belief was that growth of agricultural productivity was a prerequisite.

Fudan University Lecture 3 104

Advances in the “techniques” of selling

• Specialization between “wholesale” and “retail” merchants.

• Opening of showroom and employing traveling salesmen.

• Standardization of quality (e,g, shoe and cloth sizes).

Page 105: Fudan University Lecture 31 The Role of Agriculture in Economic Growth Standard belief was that growth of agricultural productivity was a prerequisite.

Fudan University Lecture 3 105

Emergence of marketing and advertising

• Contemporaries were increasingly bombarded with ads for goods.

• Aggressive marketing strategies can be discerned in other industries such as printing, cutlery, clocks, high-end textiles, household implements, to say nothing of medical doctors and pharmacists selling miracle drugs.

• “Promise, large promise, is the soul of advertisement.. . . The trade of advertising is now so near perfection that it is not easy to propose any improvement” (Dr. Samuel Johnson, 1759)

Fudan University Lecture 3 107

Highly innovative entrepreneur

• In addition to major inventions in the pottery industry, was a pioneer in skillful advertising and consumer manipulation (through name dropping and appeal to snobbery).

• Famous for “creamware” ---a fine white earthenware substitute for Chinese porcelain with a rich yellowish glaze; ideal for domestic ware. The cream colour was considered a fault at the time, and Wedgwood introduced a white to bluish white product called pearl ware in 1779. Supplied a tea-service set for Empress Catharina consisting of 952 pieces.

• Clever use of “fashion” and fads in textile and home decoration created demand.

Page 108: Fudan University Lecture 31 The Role of Agriculture in Economic Growth Standard belief was that growth of agricultural productivity was a prerequisite.

Fudan University Lecture 3 108

Other services:

• Medicine and Law. In medicine we have a whole range from official members of the establishment to country surgeons and quacks. Other medical professionals: accoucheurs (male midwives) and apothecaries.

• Practically no government regulation or quality control despite serious informational asymmetries. [Royal Coll. Of Medicine was an antiquated body].

• In the end, local associations of physicians merge to form the British Medical Association (1855) which eventually starts controlling entry.

Page 109: Fudan University Lecture 31 The Role of Agriculture in Economic Growth Standard belief was that growth of agricultural productivity was a prerequisite.

Fudan University Lecture 3 109

Legal Professionals

• Only “barristers” were called to the bar and could appear in courts. But otherwise unregulated, and ruled by caveat emptor.

• Most legal work done by “solicitors” and “attorneys.”

• In 1730, there are 5,500-6,000 legal professionals in Britain, in 1841 around 14,000 --- less than the rate of population growth. Society becomes less litigious?

Page 110: Fudan University Lecture 31 The Role of Agriculture in Economic Growth Standard belief was that growth of agricultural productivity was a prerequisite.

Fudan University Lecture 3 110

• In the eighteenth century courts and police protection are quite weak in Britain. Most courts were slow, judges were unpaid, no professional police except London.

• “Law and Order” was very strict when it came to crimes against property --- deterrent effect?

• For most economic transactions and contracts, enforcement relied on private order institutions rather than “third-party” enforcement.

• Property rights are very important for economic development, and are typically associated with “the state” and “government” --- but there are alternatives such as reputation mechanisms and a culture in which honesty is a dominant cultural value.

Page 111: Fudan University Lecture 31 The Role of Agriculture in Economic Growth Standard belief was that growth of agricultural productivity was a prerequisite.

Fudan University Lecture 3 111

This changes over time

• In the 1830s most judges were paid, police were professionals and clearly this system had to be modernized as the economy became more modernized.

• This is closely associated with a growth in the mobility of people and goods, and rapid urbanization.
