Abstract

Working Paper available here

Empirical investigations of many information systems phenomena are complicated by endogeneity. The Covid-19 pandemic prompted a wide range of policy and societal changes that seem to present a natural experiment. Researchers have attempted to use these changes, such as mandated closures of non-essential businesses, as exogenous shocks or instrumental variables in causal inference, with the goal of evaluating a theory or phenomenon not related to the pandemic. However, the rationale that the Covid-19 response prompted changes (such as business and school closures) that were decided by an agent “outside the unit of analysis” is not sufficient to meet the criteria for exogeneity. We concisely describe and demonstrate via simulation that the wide-ranging impacts of Covid-19—which were driven by politics, personality, and socioeconomics, and implemented in bundles—violate the parallel trends assumption for difference-in-differences analyses and the exclusion restriction for instrumental variable analyses. Our hope is that this analysis helps IS researchers avoid such problems moving forward.

Abstract

The in-kind wages paid to pre-industrial workers have recently received new attention by economic historians interested in understanding long-term living standards. However, in-kind wages are difficult to quantify leading historians to either ignore them entirely or use proxies such as consumer price index baskets of goods to capture their value. In this paper, we take a different approach by using a new dataset to directly measure the quantity, composition, and value of grain wages paid to late medieval agricultural workers across the period 1270 to 1440. This allows us to precisely measure remuneration, and the value of its cash and in-kind components, at the level of the individual worker. We use this information to evaluate the mechanisms which led to changes in labour remuneration in the period following the Black Death and differences in the effects between workers. Our results clearly demonstrate that the wages of the average adult male worker rose in the wake of the Plague, but only after a thirty-year hiatus, showing that changes in labour relations, rather than worker productivity in and of itself, drove the ‘golden age of labour’. However, preliminary investigations of variation between workers suggest a more complex story: while in the aggregate wages appear to have been similar across different manors held by the same estate, inequality in the wages paid between different types of worker were persistent, suggesting a rigidity in occupational hierarchies that was not overturned by the Plague. 

The paper is a collaboration with Jordan Claridge (LSE) and Vincent Delabastita (Radboud)

Abstract

Disciplines such as history are anthropocentric, viewing the natural world as a stage on which humans, whether “Great Men” or struggling classes, play out their roles. This talk brings together research from a range of disciplines – microbiology, anthropology, and sociology; genomics, classics, and economics – to explore the role that pathogens have played in the past. We will take a brisk ride through the recent history of our species, to see how infectious diseases played critical roles in many of the great social, political and economic transformations, from the emergence of Christianity and Islam as world religions, to the transition from feudalism to capitalism.
