This article provides for the first time a robust quantitative estimate of the amount of syphilis infection in the population of London in the later eighteenth century. A measure of the cumulative incidence of having ever been treated for the pox by the age of 35 is constructed, providing an indicator of over 20 per cent syphilitic infection. The principal primary sources are hospital admissions registers, augmented with an analysis of London's workhouse infirmaries. A range of potentially confounding factors are taken into account, including the contemporary conflation between syphilis and other sexually transmitted infections, patients who shunned hospitals in favour of private treatment, possible double‐counting of patients, institutional patients who may have hailed from outside London, and the complexity of establishing what should constitute the 'at‐risk' population of London for this period. Cultural and medical historians have demonstrated considerable pre‐occupation with venereal disease in the texts of the eighteenth century, while demographic and epidemiological historians, lacking any quantitative evidence, have tended to ignore the disease. This article can now demonstrate for the first time just how extensive syphilis was likely to have been and, by doing so, offer an original contribution to major debates in the history of sexuality and the demography of early modern London.

This article provides new information and data on the work and pay of skilled and semi‐skilled men on a large London construction project in the early 1700s. It offers firm‐level evidence on the employment relation in the construction industry at the time and sheds some light on the number of days worked per year and per week, showing that employment was more irregular and seasonal than current estimates of income infer. The patterns are considered in the context of new debates about industriousness and economic growth. [ABSTRACT FROM AUTHOR]

This article draws on quantitative and descriptive data from Robert Campbell's manual for prospective apprentices, The London tradesman (1747), to demonstrate the responsiveness of apprenticeship premiums in mid-eighteenth-century London to market forces of supply and demand. It first shows that Campbell's data on mid-eighteenth-century journeymen wages, apprenticeship premiums, and masters' set-up costs in London are consistent with other sources. It then applies instrumental variable regressions to estimate the elasticity of apprenticeship premiums with respect to journeymen wages and set-up costs, using Campbell's education and ability requirements by trade to instrument for wages. We find an elasticity of one with respect to wages, and of 0.25 with respect to set-up costs, both statistically significant at a p-value less than 0.1%. We interpret these findings as supporting the thesis that apprenticeship played an important role in adapting the English workforce to the skill requirements of the industrial revolution in its early stages, insofar as the institution of apprenticeship in London was representative of other parts of England. Furthermore, by demonstrating the internal and external consistency of Campbell's observations, our findings should encourage their use as an unparalleled source of detailed, trade-specific wage data from the early years of the industrial revolution.

This article examines the impact of information asymmetry on the movement of London- Antwerp exchange rates against the backdrop of the Great Debasement of 1544-51. The case of the revaluation of gold coins in the Habsburg Netherlands in 1539, about which the sovereign and the public possessed similar information, is used as the benchmark to judge how far the speed of adjustment was affected by information asymmetry. This article is also part of the recent literature that estimates the degree of financial market integration in late medieval and early modern Europe. In the framework of the threshold autoregressive model, the speed of adjustment and the transaction costs associated with arbitrage are estimated, and the results are judged using the speed of communication as a benchmark since the flow of information played a critical role in financial arbitrage. The results reveal that the sixteenth-century London- Antwerp exchange markets were already as integrated as that during the late nineteenth century, but information asymmetry severely disturbed the effectiveness of exchange arbitrage.

This article uses newspaper advertisements to chart the changes in speeds and fares of stage coaches, identifying the main periods of increasing speeds among London coaches as the 1760s-80s and 1810s-20s, separated by a period when speeds declined. It then measures productivity growth. Fares of London coaches in 1835-6 were about 27 per cent of what they would have been but for improvements in horses, vehicles, and roads from 1750, and the two main periods of productivity growth correspond to those of rising speeds. Speeds and productivity of regional coaches increased more smoothly. The rising productivity firmly identifies road transport as one of the modernizing sectors of the economy. New figures are put forward for the growing number of London and regional coaches, indicating rapid growth in passenger miles. While turnpike trusts had little impact before the 1750s, their increasing effectiveness, together with the use of steel springs and improved horses, was crucial to the rising productivity of the 1760s-80s, and even more so to that of the 1810s-20s. The cross roads were apparently poorer than London roads in the late eighteenth century, but thereafter the gap narrowed. [ABSTRACT FROM AUTHOR]
