Sheilagh Ogilvie on Epidemics, Guilds, and the Persistence of Bad Institutions

Economic historian Sheilagh Ogilvie, author of Controlling Contagion: Epidemics and Institutions from the Black Death to COVID, talks with Tyler Cowen about why the Black Death’s ‘silver lining’ is mostly myth, how 18th-century England ran a franchise industry in smallpox variolation, why local government beat central government at epidemic control, and why guilds — like the European marriage pattern — persisted for centuries despite doing more harm than good.

Key ideas

1. Historical epidemics inflicted a genuine ‘double whammy’. People withdrew from markets voluntarily out of fear, and formal containment measures piled a second, separate cost on top — a pattern Ogilvie finds was proportionally larger in medieval and early modern epidemics than in COVID, partly because pre-modern households had no savings cushion and no state support for observing lockdown.
2. The Black Death’s ‘silver lining’ is mostly a comforting story. Wages did eventually rise in Western Europe, but only decades later, and the story ignores that Eastern Europe’s response to the same labour shortage was the opposite: landlords tightened coercive control over serfs, producing the ‘second serfdom’ rather than a free bargain.
3. 18th-century England ran variolation like a franchise business. Village friendship groups paid commercial variolators to inoculate them together as a rite of passage before moving to London, on an openly stated cost-benefit calculation — roughly 1.6 percent mortality from variolation against 10–20 percent mortality from natural smallpox.
4. Local government consistently outperformed central government at epidemic control. Local authorities had better information about neighbours’ behaviour and local welfare needs; central government’s chief value was coordinating across localities, since epidemics generate cross-border effects no single village has an incentive to manage.
5. Guilds and the European marriage pattern both persisted well past the point of net harm. Guilds functioned largely as entry-restricting cartels — excluding women, Jews, migrants, and, in one documented Spanish case, anyone with skin darker than quince jelly — while the European marriage pattern’s link to economic growth breaks down once Ogilvie compares stagnant serf economies that shared the same demographic profile as England and the Netherlands.

Epidemics as a double economic shock

Ogilvie frames historical epidemics as inflicting damage through two separate channels: voluntary market withdrawal, driven by fear, and formal restrictions imposed to limit contagion. Quantifying the balance is hard — the surviving evidence is fragmentary micro-data, such as a 90 percent collapse in merchants’ use of the postal system in 17th-century Italian cities during plague, rather than usable whole-economy GDP figures. What data exists suggests voluntary withdrawal was proportionally larger in medieval and early modern epidemics than in 20th- or 21st-century ones, because pre-modern populations had thinner savings cushions and no institutional income support for observing lockdown until the late medieval period. Asked why the 1969 ‘Hong Kong flu’ pandemic left so little economic or cultural trace, she admits it is a genuinely open question — even people who lived through it, herself included, barely remember it happening.

The Black Death’s silver lining, examined

The claim that the Black Death was secretly good for Europe — killing enough workers to raise wages and spur labour-saving innovation — Ogilvie calls ‘mostly a happy story.’ The scale of death (30–60 percent of the European and Middle Eastern population, worse than any pandemic for which records exist) meant survivors spent years amid deserted villages and dead employers before any wage gain materialised; the redistribution toward workers did not properly begin until the later 14th or early 15th century. Crucially, the outcome diverged by region. Western Europe saw a genuinely freer labour bargain, including outrage at women demanding higher wages to stay in their villages. Eastern Europe saw the opposite: facing the same labour scarcity, feudal landlords strengthened control over unfree peasants, producing the ‘second serfdom.’ Pressed on the theoretical puzzle — falling labour demand should offset falling labour supply — Ogilvie points to employers’ own contemporary lobbying for wage-suppression laws as evidence that upward wage pressure was real, whatever the pure supply-and-demand arithmetic suggests.

Variolation: the franchise industry that predated vaccination

Variolation — deliberate inoculation with a weakened dose of live smallpox, distinct from Jenner’s later cowpox-based vaccination — appears to have arisen independently in multiple societies; the earliest documented practice, complete with a hereditary dynasty of commercial variolators, is in 1560s China. It reached England in the early 18th century via two simultaneous channels: an East India Company surgeon’s letter to the Royal Society, and Lady Mary Wortley Montagu, who had witnessed it in Constantinople, variolated her own children, and then made it fashionable among the English aristocracy — an early instance of social ‘influencing.’ The individual cost-benefit case, openly stated by contemporary doctors, was compelling: roughly 1.6 percent mortality from variolation against 10–20 percent from natural smallpox. England developed a genuine commercial franchise industry around it — the Sutton family’s operation being the most famous — that later spread to continental Europe and North America; teenage friendship groups would get variolated together before leaving their village for London. Asked whether the same ‘variolation’ logic should have been applied to COVID-19, as Robin Hanson suggested, Ogilvie is doubtful: COVID is viral, and variolation was a genuine immunisation mechanism rather than a herd-immunity strategy.

Local versus central authority in epidemic control

Against the state-capacity literature’s emphasis on central government effectiveness, Ogilvie argues the historical record favours local autonomy for epidemic control specifically. Local authorities had superior information — about who was keeping their well clean, who was getting variolated, who genuinely needed welfare support to observe quarantine — sustained by informal neighbourly monitoring she calls the ‘curtain-twitching effect.’ The limitation is that epidemics generate cross-border externalities no single village has an incentive to internalise; higher levels of government added most value by coordinating across localities rather than by direct intervention. On COVID-era Britain, she credits the rapid Oxford vaccine rollout but criticises the ‘Eat Out to Help Out’ restaurant subsidy — linked by a Warwick economist’s analysis to a subsequent spike in infections and deaths — and Britain’s slow, age-cohort vaccine queue, contrasted with market-based access she observed in Germany, France, Canada, and the US. She reads this as a historical reversal: Britain pioneered market-provided variolation in the 18th century but did not mobilise market provision of vaccination in the 21st.

Why people opposed inoculation, then and now

Historical opposition to variolation and vaccination, Ogilvie argues, came disproportionately from religious extremes — Jansenist Catholics in France, dissenting Protestant sects in Germany and Scandinavia — rather than from a generic distrust of authority, since these groups held strong convictions about their own authority. She models religion as a bundled ‘platform’, comparable to Amazon: accepting anti-vaccination doctrine can be the entry price for the spiritual consolation, charitable relief, and social networking a religious community otherwise supplies. In France and Spain, medical guilds allied with the Catholic Church to lobby successfully for variolation bans, protecting members’ fee income from treating smallpox patients — an alliance she regards modern medical associations as not comparably prone to, despite scattered contemporary ‘renegade’ anti-vaccine medics.

Dastardly guilds

Ogilvie’s own research area gets its most direct airing here. Steelmanning guilds, she credits some — notably Dutch and English — with genuinely effective vocational training, and singles out London’s guild system as unusually flexible: apprenticeship in any one guilded trade conferred the right to practise any other. The case against dominates. Guilds fundamentally excluded on grounds of sex, religion, poverty, and migration status; an 18th-century Spanish cobblers’ guild excluded any boy whose skin was darker than quince jelly, a literal, merit-blind colour bar. Her general diagnosis is that guilds functioned as cartels, restricting entry to sustain members’ prices, and enforced quality standards that priced out the cheaper, lower-quality goods poorer consumers would have preferred. Asked about guilds’ cultural legacy — Florentine art, Hanseatic architecture — she judges the economic damage clearly outweighed the benefit, comparing the surviving beauty to Versailles: splendid monuments built on rents nobody would want to restore the underlying social order to obtain.

The European marriage pattern, English growth, and social mobility

The European marriage pattern — late female marriage, high lifelong celibacy, nuclear households — is often credited with enabling England’s and the Dutch Republic’s economic take-off, since both exhibited the pattern beforehand. Ogilvie’s counter-evidence: the same pattern also prevailed in stagnant, serf-based economies across Eastern, central, and Nordic Europe that did not industrialise until the late 19th century, which undercuts a simple causal story. Her preferred account, at least partly speculative, reverses the arrow for the least-developed cases: extreme early and universal marriage may substitute for missing institutions — pensions, welfare, secure property rights — rather than independently causing stagnation, a frame she extends cautiously to contemporary Sub-Saharan Africa. On England’s own take-off, she is comfortable dating sustained growth to the 17th century, driven by a cluster of institutional changes — a livelier market, rising but non-authoritarian and largely local state capacity, a strong legal system with minimal bureaucracy, and weakening guilds — that had already appeared in the 16th-century Low Countries. The Dutch Republic’s subsequent 18th-century stagnation she attributes to institutional ossification: guilds re-restricted after their 16th-century liberalisation, and the Dutch East India Company’s dominance let entrenched producers block innovation. She largely disagrees with Greg Clark’s thesis of persistently low English social mobility, arguing that against her own comparison set — German-speaking central Europe, where legal social status was formally entrenched — England looks comparatively mobile.
