Porridge to Progress: Economic Development through
the Lens of Wage and Price History
Bob Allen
New York University Abu Dhabi
2015
Objectives today:
• Describe my project of writing wage and price history of the world
• Discuss implications for--– measuring market integration & globalization– Measuring standard of living– Incentives to adopt modern technology
Wage and price history
• First price histories written in mid19th century• Based on surviving accounts of institutions that lasted
hundreds of years• Historian abstracts prices from all transactions and
wages paid to all employees• Large tables in local money and units of weight and
measure in many languages.• Since 1980s, I have been putting them in spreadsheets
and converting units.• Data on my website (www.nuffield.ox.ac.uk) and
elsewhere.

Labourers' wages around the world
How do the wages map into living standards? We must measure the cost
of living:
• Collect prices of all of the important consumer goods.
• These must be converted to grams of silver per metric unit.
• A basket of goods must be specified and its cost computed.
What was the subsistence wage in England in the Industrial Revolution?
• Sir Frederick Eden, The State of the Poor, 1797, Vol. II, pp. 433-4, reports on an Ealing gardener.
• Aged 40, regularly employed, with a wife, and four children aged 8, 6, 4, and 1-1/2
• He seems fairly typical.

Measure living standard with ‘respectability ratio’
• Annual family income = 250 * daily wage• Cost of maintaining a family at subsistence
– Add 5% to budget for rent– Family = 3 adult male equivalents– Annual subsistence cost = 3.15 * cost of basket
• Respectability ratio = annual income/annual cost of subsistence
• In late 1790s, annual subsistence cost was about £25.5, so the Ealing gardner’s ratio= 28.75/25.5 = 1.12 on regular earnings.

The Rest Falls Behind Northwest Europein the standard of living of labourers
What would Malthus, Ricardo, and Marx say?
• Pleased that labourer’s real wage was just above subsistence and flat for 500 years
• However, English real wage was very much above wages elsewhere in the world.
• The Rest couldn’t afford the basket. How did they rest survive?
• Symptom: many proxy variables in Asian baskets
How did the poor survive?
• More people worked more– Not too effective since women & children earned
such low wages
• Spent less money– Got rid of expensive sources of calories– Diet reduced to cheapest available carbohydrate,
beans, very little meat and oil
• Other changes in basket– Calories set at 2100 per person– Four people per household
Such baskets correspond to the World Bank Poverty Line of $1.25 per person per day.
When the subsistence ratios are calculated with these baskets, the geometry is the same but the
absolute levels are lower.

Subsistence Ratio for Labourers
income/cost of subsistence basket
Roman Empire (Diocletian price edict 301 AD)
Some implications
• Real wage in poor countries in eighteenth century was at barebones subsistence = WBPL
• Classical economists’ idea of subsistence (respectability) was over twice the cost of barebones subsistence = WBPL.
• Great divergence preceded the Industrial Revolution (indeed, caused it).
We can apply these measures across time and space
Laborers’ wages at the exchange rate were much lower in countries
with large native populations.

Incentives to adopt modern technology
Since the Industrial Revolution, a lot of ‘modern’ technology has
• Raised labour productivity by increasing the capital-labour ratio
• Raised labour productivity by increasing the energy-labour ratio
• If ‘modern’ technology has different factor proportions from ‘older’ technology, then relative factor prices could—and did!—play a major role in the invention and diffusion of modernity.
Why do rich countries use highly mechanized power looms?
While 300,000 Ethiopians still weave cloth with handlooms?
Why is the K/L ratio high in placer gold mining in California?
While the K/L ratio is low in placer mining in Ghana?
The breakthrough technologies of the IR raised labour productivity by increasing K/L.
Not an accident: Eighteenth century Britain was unique because its labour was very expensive
relative to capital.

Since IR, incentives to adopt modern technology have been very different in rich countries and poor
countries.
