Were real wages in the Yangzi delta and Bengal comparable to England's before 1750?

The date of the Great Divergence decides between rival explanations of why industrialisation began in north-western Europe. If the Yangzi delta and Bengal matched England until about 1750 or 1800, as Pomeranz and Parthasarathi argued, the divergence is best explained by late and contingent factors such as coal and access to New World land and markets; if they had fallen behind by 1600 or 1700, longer-run explanations based on institutions, demography or innovation gain ground. The answer also shapes judgments about the economic effects of Qing rule and of East India Company rule in Bengal after 1757.

The Chinese and Indian real-wage series rest on comparatively few quotations, often for different occupations, places and decades, drawn from construction regulations, merchant account books, gazetteers and European company records. Wages paid partly in kind, uncertain days worked per year, multiple monies (silver by weight, copper cash, rupees of varying standard) and local units of grain make each observation hard to convert. Results also move with the choice of consumption basket and deflator, so silver wages, grain wages and welfare ratios have supported different conclusions from much the same evidence, and critics such as Deng and O'Brien question whether the data can bear the comparison at all.

Welfare-ratio series for the Yangzi delta and for Bengal, each built from at least two independent record types that agree within stated error, decade by decade from 1600 to 1800, with the point at which they fall below England located within a stated interval that holds under alternative baskets and deflators.

• The positions are well defined. Pomeranz (2000) and Parthasarathi (1998, 2011) argued that the advanced regions of Asia matched England until the later eighteenth century; Broadberry and Gupta (2006) answered that grain wages were similar but silver wages much lower, and Allen et al. (2011) placed eighteenth-century Chinese building workers alongside the poorer parts of Europe. Allen (2009), Li and van Zanden (2012) and Broadberry, Guan and Li (2018) compared the Yangzi delta directly with England and the Netherlands, while Roy (2010), Sivramkrishna (2009) and de Zwart and Lucassen (2020) did the same for Bengal and other Indian regions.
• The first step is a single, citable register of every wage and price quotation already used, linked to its archival source, with original units and currencies recorded. Deng and O'Brien (2016) showed how thin and heterogeneous the Chinese base is, and the files gathered by the Global Price and Income History Group and the Historical Prices and Wages archive, including the Qing wage regulations, are the obvious starting point.
• AI research agents could then extract new quotations at scale from records that are digitized but not tabulated: prices from the Qing Grain Price Database and the palace memorials in the First Historical Archives, wages and purchases in Huizhou documents, and payments to labourers, weavers and boatmen in the Kasimbazar, Dacca and Hugli factory diaries and in the VOC's Overgekomen Brieven en Papieren now being transcribed by GLOBALISE. Every conversion of units and monies should be stated and reversible.
• Independent series should then be tested against each other: official construction wages against wages paid in merchant account books, company wages against Mughal and regional price data, and grain-price trends against silver-copper exchange rates. Liu (2023) extended Chinese wages back to 1530 by combining sources, and the disagreement between Rawski (2025) and Broadberry, Guan and Li over error margins shows why uncertainty must be modelled explicitly.
• With the series in hand, the crossover with England can be estimated under the respectability and bare-bones baskets, with and without climate and household adjustments, to see whether the date is robust. Progress depends on wider imaging of Huizhou account books and Bengal factory records and on economic historians who read classical Chinese, Persian, Bengali and early modern Dutch checking extracted values before they enter the series.

economists

Rebuild Yangzi delta and Bengal welfare ratios decade by decade for 1600 to 1800 under several baskets and deflators, reporting where each places the crossover with England.

archivists and librarians

Identify and image the Huizhou account books and Bengal factory diaries that record wages and prices, with item-level finding aids so each quotation can be traced.

statisticians and data scientists

Fit a model that pools wage and price quotations of different kinds, places and units, and propagate measurement and conversion uncertainty into each decade's welfare ratio.
