HISTORICAL NATIONAL ACCOUNTING • Until surprisingly recently, there was no systematic quantitative overview of the basic contours of long run economic development • Although there were a few isolated studies with data on individual parts of a number of European economies, there had been no attempt to pull them together • The pioneer here was Angus Maddison, who spent a lifetime developing an approach known as “Historical National Accounting” 5 Historical National Accounting • I will end up suggesting that Maddison’s estimates are seriously misleading and are in the process of being replaced • But that should not take away from the magnitude of his achievement. He was unambiguously the pioneer of a great project, which remains to be completed 6 1. THE MADDISON DATA SET • Quantification of world economic history received a major boost with the publication of Maddison’s (2001), World Economy: A Millennial Perspective • Until the early 1990s, data on comparative levels of per capita income were largely restricted to the “Maddison 16” of rich industrialised countries and covering only the period since 1870 7 The Maddison data set • Following an explosion of interest in the production of historical national accounts, by 1995 Maddison was able to extend estimates back to 1820 for many rich industrialised countries and back to 1870 for many other countries • Maddison’s 2001 volume is much more ambitious, and aims to provide global coverage for the period back to 1820 and rough estimates back to 1000 for selected economies • Final version from 2010 available on GGDC website 8 What Maddison’s data show • TABLES 1 & 2: Between 1000 and 1998, population rose 22-fold, per capita income rose 13-fold. In previous millennium, population increased by onesixth and per capita income fell slightly. • Two distinct epochs in 2nd Millennium: – Between 1000 and 1820, p.c. income increased by 50%, population rose by a factor of four. Growth was largely extensive – Since 1820, more intensive development (g of p.c. income > g of pop). Pop increased by factor of < 6, p.c. income increased by factor of > 8 9 TABLE 1: Level and rate of growth of population: World and major regions, 0-1998 A.D. 0 1000 1820 1998 (million) 15.4 132.9 2.0 11.2 7.5 31.0 34.9 175.1 388 323 126 838 0-1000 100018201820 1998 (annual average growth) 0.00 0.20 0.60 0.05 0.21 1.91 0.09 0.17 0.79 0.02 0.20 0.88 Western Europe Western Offshoots Japan Total Group A 24.7 1.2 3.0 28.9 Latin America E.

Offshoots, Japan – Group B: Latin America, E.Europe & Former USSR, Asia (except Japan), Africa • Growth of p.c. income 4 times as fast in Group A as in Group B. – – – – Group B was ahead in 1000 (after fall of Roman Empire). By 1820 p.c. income in Group A twice level in Group B. By 1998 ratio had increased to 7:1 In 1998, p.c. income ratio between W.Offshoots and Africa more than 19:1. Africa today at W.European level of 1820 12 What Maddison’s data show • For Group A countries, at least, Malthus was clearly too pessimistic about the possibility of increasing living standards in the long run • TABLE 3: Changing regional shares of GDP: – In 1000, Asia produced two-thirds of world GDP and W.Europe less than 9% – By 1820, W.Europe’s share 24%, Asia’s share 56% – By 1998, Asia’s share 30%, W.Europe and W.Offshoots 46% 13 TABLE 3: Level and rate of growth of GDP: World and major regions, 0-1998 A.D. 0 Western Europe Western Offshoots Japan Total Group A Latin America E.

Pattern is sometimes described as the Little Divergence • Italy had highest per capita income during 1000-1500 • After “voyages of discovery”, brief Iberian boom, but opening up of Atlantic economy led eventually to economic leadership of NW Europe: first NL, then GB 15 TABLE 4: GDP per capita in UK and selected countries, 1500-1820 (1990 international dollars) Belgium France Italy Netherlands Portugal Spain United Kingdom Total Western Europe 1500 875 727 1,100 754 632 698 714 774 1600 976 841 1,100 1,368 773 900 974 894 1700 1,144 986 1,100 2,110 854 900 1,250 1,024 1820 1,319 1,230 1,117 1,821 963 1,063 1,707 1,232 16 2. BASIS OF THE POPULATION ESTIMATES • Data from the past exist largely as a result of government efforts to raise taxes • China: bureaucracy kept population registers going back more than 2000 years. Designed to assess taxable capacity, also included information on cultivated area and crop production • Roman Empire: conducted censuses for fiscal purposes 17 Population • England: Domesday Book 1086 extraordinarily detailed survey of whole country, broken down by estate. • A number of economic historians have used Domesday data to estimate English population in 1086 (Russell, 1948; Darby, 1977) • Others have also used Domesday Book to estimate national income for England in 1086 (Snooks, 1995; Mayhew, 1995; Walker, 2015) 18 Population • Parish registers in many countries record births, marriages & deaths • Decadal censuses now the norm in many countries • Scope for disagreement small after 1700 • Even between 1000 and 1700, fair amount of agreement between scholars • There is some scope for improving on Maddison’s population estimates, but it is probably more about increasing the frequency of observations than changing the trends 19 3. BASIS OF THE INCOME ESTIMATES • For many countries, historical national accounts have been reconstructed since about 1870 • Going back further in time, for “core” countries there is quite a lot of hard evidence that can be derived from archives: – cultivated land use, crop yields and animal numbers from farm accounts and tithe receipts – population living in towns and labour force occupations – extent of foreign trade – wages, prices and real wage trends – government spending and revenue 20 Basis of the income estimates • However, despite encouraging economic historians to produce GDP estimates based on hard data, Maddison preferred to rely largely on “guesstimates” for the pre-1870 period • His approach was to use some basic assumptions, particularly about the subsistence level of income, and make some freehand adjustments on the basis of the qualitative literature • This is best understood if we consider how Maddison made his international comparisons and established the subsistence level of income 21 4. INTERNATIONAL COMPARISONS • It is important to compare wages and GDP per capita at Purchasing Power Parity (PPP) • British wages will be in £, while US wages will be in $ • Cannot simply compare at the exchange rate, which may move to clear international asset markets, rather than reflecting the price of goods and services that people living in the 2 countries buy 22 International comparisons • Compute the PPP by comparing prices of individual products, weighted by their importance in the GDP of the 2 countries • Would get a different PPP if use UK weights rather than US weights • A compromise estimate is obtained by using the geometric mean of UK and US weights • However, a series of bilateral comparisons made this way may not be transitive 23 International comparisons • Maddison therefore chose to use a set of international weights for comparing all countries • Most international comparisons are now carried out in 1990 GK international dollars (named after Geary and Khamis who derived the weighting scheme) 24 1990 international dollars • Using PPPs for 1990, we can convert GDP per capita for all countries to 1990 international dollars • This provides a convenient standard for comparing per capita incomes over space and time • World Bank standard in 1990 suggested “bare bones subsistence” is $1 per day, or $365 per year • Since any society has a rich elite, minimum average per capita income for any society likely to be around $400 • This is widely regarded as “bare bones subsistence” 25 1990 international dollars • Now look at the early observations in the Maddison data set and notice how many are at or very close to $400 in the early years • Better off economies are put slightly above this level, at $425 or $450 • Observations between 1000 and 1820 are then more or less drawn in freehand, so as to conform to Maddison’s views on the major controversies in global economic history 26 5. INTERNATIONAL COMPARISONS BEFORE 1870: THE GREAT DIVERGENCE DEBATE • A central issue in international comparisons before 1870 concerns the Great Divergence of living standards between Europe and Asia • But which Asian regions should be compared with which European countries? • Maddison compares W.Europe with China, but the Yangzi Delta region of China may not have been so far behind even by 1800 27 Maddison’s Great Divergence • Pomeranz claims the Yangzi delta was on a par with GB & NL in 1800, but this has not been widely accepted • Maddison’s figures for W.Europe and China show a more conventional picture (TABLE 5): – After the fall of the Roman Empire, W.European p.c. income fell to a low point circa 1000. – Chinese incomes were stagnant, so W.Europe fell behind 28 TABLE 5: Comparative levels of GDP per capita in China and Western Europe, 400-1998 A.D. (1990 international dollars) 400 700 1000 1300 1500 1700 1820 1870 1913 1950 1973 1998 W.

Venice), then Portugal & Spain, then NL, then GB – A growth rate of 0.14% p.a. was not very fast but by 1820 p.c. income in W.Europe had tripled (compound interest) – Chinese p.c income also grew between 1000 and 1300, but more slowly than W.Europe. So W.Europe caught up with China by C14th 30 Maddison’s Great Divergence – Chinese p.c. income then stagnated until 1820. Initially due to internal policies and institutions (e.g. self-imposed isolation), then reinforced by colonial exploitation by West – China fell far behind as W.Europe continued to grow. By 1820, p.c. income in W.Europe twice Chinese level – From early 19th to mid-20th century, Chinese p.c. income fell, while W.European growth accelerated 31 Maddison’s Great Divergence – By 1950, W.Europe’s p.c. income more than 10 times Chinese level – Since 1950, and esp since 1973, China has been catching up. By 1998, W.European income level less than 6 times Chinese level 32 6. IMPROVING ON MADDISON • Many of Maddison’s GDP per capita observations before 1820 are “guesstimates”, but it doesn’t have to be this way • Since Maddison died in 2010, the Maddison Project has begun the process of improving upon the original Maddison data set • Bolt and van Zanden (2014) represents the first round of improvement, and incorporates a number of series for the pre-1820 period based on hard data • Figure 2 shows the results for 4 European economies 33 TABLE 6: GDP per capita levels in Europe (1990 international dollars) 1750 1800 England/ GB 754 759 755 777 1,090 1,055 1,114 1,143 1,123 1,100 1,630 1,563 1,710 2,080 1820 1850 2,133 2,997 1086 1270 1300 1348 1400 1450 1500 1570 1600 1650 1700 Holland/ NL 876 1,245 1,432 1,483 1,783 2,372 2,171 2,403 2,440 2,617 1,752 1,953 2,397 Italy Spain 1,482 1,376 1,601 1,668 1,403 1,337 1,244 1,271 1,350 957 957 1,030 885 889 889 990 944 820 880 1,403 1,244 910 962 1,376 1,350 1,087 1,144 Sources: Broadberry et al. (2015); van Zanden and van Leeuwen (2012); Malanima (2011); Alvarez-Nogal and Prados de la Escosura (2013) 34 Improving on Maddison • The most obvious change is that levels of per capita income were substantially higher in 1500 than suggested by Maddison • Projecting back further suggests that per capita incomes in Western Europe were already well above bare bones subsistence in the 13th century, and indeed even earlier – English p.c. GDP in 1086 was about the same as in 1300 35 Improving on Maddison • In the second half of this lecture, we will explore the new British historical national accounts: – Explain where the estimates come from – Explore the implications for understanding the transition to modern economic growth 36 TOPIC 1: ECONOMIC GROWTH, 1000-1870 LECTURE OUTLINE • • • • • • • • • B.

AGRICULTURE • Data sources for 3 periods yield information on land use, arable yields, animal stocking densities etc: – Medieval period: Bruce Campbell’s Manorial Accounts Database – Early modern period: Mark Overton’s Probate Inventories Database – Modern period: Turner, Beckett and Afton’s farm accounts database 45 Agricultual output trends • FIGURE 1: Constant price output for arable and livestock sectors • Medieval period: arable output trended down, livestock output stable. Total agricultural output showed modest decline • From mid-C16th livestock first grew slower then faster than arable from mid-C17th • Total agricultural output growth increased but only modestly 46 FIGURE 1: Indexed output in English arable and livestock agriculture (log scale, 1700=100) 640 arable output pastoral output 320 160 80 40 20 10 1270 1370 1470 1570 1670 1770 1870 47 Share of livestock agriculture • Share of livestock sector rising in constant price terms, but with setback 1450-1650 • Price of livestock products declined relative to arable products 1450-1650, so share of livestock sector declined much further in current prices • Note very high share of livestock sector in late medieval period in both current and constant prices • Although kilocalories per person not particularly high, expensive kilocalories (meat, dairy produce, ale) 48 TABLE 5: Output shares in English agriculture, in current prices, 10-year averages (%) 1270s 1300s 1350s 1400s 1450s 1550s 1600s 1650s 1700s 1750s 1800s 1850s 1860s Current prices Arable Pastoral 60.1 39.9 51.2 48.8 48.8 51.2 46.3 53.7 38.4 61.6 58.1 58.1 64.5 59.7 57.8 48.5 44.8 40.0 41.9 41.9 35.5 40.3 42.2 51.5 55.2 60.0 Constant 1700 prices Arable Pastoral 69.2 30.8 66.4 33.6 53.3 46.7 57.5 42.5 53.1 46.9 60.5 58.8 64.0 61.5 54.6 45.3 44.2 44.3 39.5 41.2 36.0 38.5 45.4 54.7 55.8 55.7 49 FIGURE 2: Indexed output of agriculture, industry and services, England (1270-1700) and Great Britain (1700-1870), (log scale, 1700 = 100) 2048 1024 512 256 128 64 agricultural output 32 industrial output 16 services output 8 4 1270 1310 1350 1390 1430 1470 1510 1550 1590 1630 1670 1710 1750 1790 1830 1870 50 2.

CONSUMPTION AND OUTPUT • Can check level of consumption per head in kilocalories • Livi-Bacci: need 2,000 kilocalories per day, but some of this from home-raised and wild sources • Slavin estimates 300 kcals from poultry, fish etc. before Black Death, 200 kcals thereafter, which matches with estimates for c.1900 from Prest • Note that total kcals per head does not trend upwards, but remains constant at around 2,000. Improvements to diet come through growing share of meat and growth in the extent of processing 64 Per capita daily kilocalorie consumption of major arable crops and animal products in England 1270/79 1300/09 1310/19 1380/89 1420/29 1450/59 1600/09 1650/59 1700/09 1750/59 1800/09 1830-09 1840/49 1850/59 1861/70 Population (millions) Kcal net of seed 4.40 4.72 4.63 2.36 2.03 1.93 4.27 5.35 5.26 6.07 9.06 13.83 15.58 17.47 20.07 3,628 3,017 2,938 4,170 3,662 3,594 3,226 3,026 3,451 4,051 3,337 2,825 2,908 2,382 2,233 Arable % food Kcal from Kcal net grain of seed, extraction imports rate losses & fodder 0 49 1,771 0 53 1,610 0 53 1,561 0 49 2,056 0 46 1,702 0 47 1,698 0 52 1,677 0 51 1,540 0 51 1,752 20 42 1,709 166 42 1,414 157 45 1,279 304 46 1,342 516 44 1,050 917 45 1,013 Kcal from poultry, fish 300 300 300 200 200 200 200 200 200 200 200 200 200 200 200 Pastoral Kcal from Kcal from meat meat & imports dairy produce 0 117 0 131 0 122 0 191 0 230 0 264 0 206 0 169 0 210 0 319 0 385 0 311 6 308 10 328 22 320 Total Kcal 2,188 2,041 1,983 2,447 2,132 2,162 2,082 1,909 2,162 2,248 2,165 1,947 2,160 2,104 2,471 65 Consumption • English society under pressure in half century before Black Death. Difficult to see how bigger population could have survived • Further periods of pressure in C17th as population recovered and early C19th before substantial grain imports • Large livestock sector provided varied diet but not many more kilocalories, so English population does not seem well off if assess living standards in terms of kilocalories • But large proportion of population able to consume meat, dairy produce and ale • In a strongly Malthusian economy, with real wages driven down to bare bones subsistence, bulk of population would derive most of their kilocalories from inferior grains with little processing (e.g. oatmeal) • Social tables suggest 24.2% unable to afford respectability basket in 1688, 39% in 1290 66 7. INCOME AND OUTPUT-BASED MEASURES • Per capita GDP plotted together with real wages of unskilled building workers in FIGURE 5 • There are differences between the Clark and Allen series, but bigger difference is between both real wage series and GDP per capita • 2 main periods of divergence: “golden age” of C15th and “Engels’ pause” of 2nd half of C18th 67 FIGURE 5: Indexed daily real wage of an unskilled building worker and GDP per capita (10-year moving averages, mean of 1270-1870=100, log scale) 320 160 80 Allen Clark 40 GDP/cap 20 1270 1320 1370 1420 1470 1520 1570 1620 1670 1720 1770 1820 1870 68 Golden Age of C15th and Engels’ Pause • Real wages increased faster than GDP p.c. 1340s-1450s then declined between 1450s and 1650s while GDP p.c. remained stable • Peak wage rates of mid-C15th not seen again before mid-C19th, hence important in creating impression of no long run progress • During 2nd half of C18th, real wages flatlined while GDP p.c. continued to grow steadily 69 Real wages and GDP per capita • Angeles (2008) relates changes in real wages to changes in GDP p.c., labour’s share of income, labour supply per person and relative prices: (𝑤 /𝑝 𝐶 )1 (𝑤 /𝑝 𝐶 )0 = −1 −1 𝐶 𝑌 (𝑌/𝑁)1 (𝛼 1 ) (𝐿/𝑁)1 (𝑝 /𝑝 )1 (𝑌/𝑁)0 (𝛼 0 ) (𝐿/𝑁)0 (𝑝 𝐶 /𝑝 𝑌 )0 70 Real wages and GDP per capita • Daily real wage could stagnate while GDP per capita increases if: • (1) Labour’s share of national income falls • (2) People work more days per year • (3) Price of basic consumption goods rises relative to price of all goods 71 Real wages and GDP per capita • TABLE 11: Uses the Angeles decomposition to simulate change in annual days worked, given trends in real wages, GDP p.c., labour’s share and relative prices • Results for 1750s-1800s consistent with those of Angeles: labour supply is most important factor in reconciling positive p.c. GDP growth with falling real wages, although rising relative price of consumer goods also plays a role 72 TABLE 11: Explaining the divergence between GDP per capita and real wages (1700=100) Real wage (w/pC) GDP per capita (Y/N) Labour’s share (α) Relative prices (pC/pY) Simulated labour supply (L/N) 1300s– 1340s 5.5 2.8 -5.1 4.4 -11.5 Percentage change over the period 1340s– 1450s– 1650s– 1750s– 1450s 1650s 1750s 1800s 75.0 -50.4 15.2 -3.6 30.6 4.2 48.3 19.6 15.3 -8.5 -1.7 -0.2 -6.4 8.0 -0.7 9.2 -8.0 78.0 27.4 13.4 1800s– 1860s 59.7 46.5 12.1 1.6 1.2 73 “Golden Age” of C15th • 1340s to 1450s: real wages able to grow faster than GDP per capita mainly because of labour’s rising share, but also because food was becoming relatively cheap • 1450s to 1650s: GDP p.c. stable while real wages fell largely because of “industrious revolution” • Subsidiary roles for increase in relative price of food and fall in labour’s share 74 Variations in Labour Supply • TABLE 12: Independent estimates of days worked per year broadly consistent with this picture of an industrious revolution • Voth uses court records to suggest sharp increase between 1760 and 1800 • Clark and van der Werf use daily and annual wage rates to suggest similar scale of increase, but more gradual process 75 TABLE 12: Estimates of annual days worked per person Period 1433 1536 1560-1599 1578 1584 1598 1600-1649 1650-1699 1685 1700-1732 1733-1736 1760 1771 1800 1830 1867-1869 1870 Blanchard/Allen and Weisdorf 165 180 Clark and van der Werf Voth 257 260 210 259 266 276 312 286 295 258 280 333 336 293-311 318 76 Variations in Labour Supply • Allen and Weisdorf use Blanchard’s data on workers who combined farming and mining in the Mendips to show similar level of days worked in late C16th to Clark and van der Werf • Also show much smaller number of days worked in period before post-Reformation reduction in holy days • Growth of annual incomes thus consistent with stagnation in daily real wages because of “industrious revolution” 77 8. BRITAIN IN A COMPARATIVE PERSPECTIVE • Projecting back from Maddison’s 1850 figure of p.c. income in 1990 international dollars suggests for Late Middle Ages a figure of around $1,100 • This is well above Maddison’s $400 subsistence income, observed for many poorer countries in 20th century • Little Divergence: Holland and then GB forged ahead of Italy and Spain during C17th and C18th • Asian GDP per capita already much lower in early modern period 78 GDP per capita levels in 1990 international dollars England/ GB 725 900 980 1020 1050 1086 1120 1150 1280 1300 1348 1400 1450 1500 1570 1600 1650 1700 1750 1800 1850 Holland/ NL Italy Spain Japan China India 551 476 1,247 1,518 1,458 1,204 1,063 754 679 755 777 1,090 1,055 1,114 1,143 1,123 1,110 1,563 1,710 2,080 2,997 876 1,245 1,432 1,483 1,783 2,372 2,171 2,403 2,440 1,752 2,397 1,482 1,376 1,601 1,668 1,403 1,337 1,244 1,271 1,350 1,403 1,244 1,350 957 957 1,030 885 889 889 990 944 820 880 910 962 1,144 508 552 552 605 619 597 622 703 777 960 983 1,127 968 977 841 685 597 594 682 638 622 573 569 556 79 Europe before the Industrial Revolution • Importance of mixed agriculture with a large livestock sector in North Sea area • This meant production had a number of characteristics important for development: – – – – high value added capital intensive non-human energy intensive enhanced employment opportunities for females, underpinning European marriage pattern • NW Europe pulled ahead as these production techniques spread to industry and services and EMP encouraged human capital formation 80
