* Firm Adaptation in Production Networks: Evidence from Extreme Weather Events in Pakistan
écrit avec Johannes Boehm & Mazhar Waseem
This paper considers how far private adaptation may reduce future vulnerability to climate
change. Firms’ climate risk exposure depends not only on the location of production, but also
on network effects via the flood risk profile of suppliers and transportation links connecting
trading partners. We use data on monthly firm-to-firm transactions for the near-universe of
formal sector manufacturing firms in Pakistan and more than six billion observations from
commercial trucks traveling on the road network from 2011 to 2018 to study adaptation of
firms in production networks. We find that firms affected by major floods relocate to less flood-prone
areas, diversify their supplier base, and shift the composition of their suppliers towards
those located in less flood-prone regions and reached via less flood-prone roads. Identification
strategies that exploit both firm- and route-level flooding suggest that these responses reflect
forward-looking actions to reduce future vulnerability to flood risk rather than direct effects of
flooding, and are consistent with experience-based updating. We develop a quantitative spatial
model of endogenous production network formation among firms that learn about flood risk
from realized flood events. We estimate the model to quantify the importance of the adaptive
responses identified for the aggregate vulnerability of the economy to future flood risk. The
results suggest that the impacts of climate change will be mediated as firms learn from the
experience of increasingly frequent climate disasters

Growth, Prosperity and Inequality in a Pre-Modern Complex Agrarian Economy: the Case of Babylonia in the Age of Empires (6th Cent. BCE)"
This paper presents quantitative and qualitative economic data from Ancient Babylonia in the Iron Age, arguing that it is possible to describe macro-economic trends that led to economic growth, greater
(median) prosperity and, concomittantly, to greater inequality. This is possibly the earliest test case for studying the nexus between these phenomena based on statistically (more or less) sound reasoning.

Early Life Conditions and Old Age Mortality
This presentation will summarize ongoing work examining impacts of early life environments in the early 20th Century in the US and associated effects on longevity for these cohorts using newly released linked data between the 1940 Complete Count Census and Death Records. Specific examples include in utero exposure to pollution, natural disasters, and clean water.
