Overview and Paper
Dario Caldara and Matteo Iacoviello construct a measure of adverse
geopolitical events and associated risks based on a tally of newspaper
articles covering geopolitical tensions, and examine its evolution and
economic effects since 1900. The geopolitical risk (GPR) index spikes
around the two world wars, at the beginning of the Korean War, during
the Cuban Missile Crisis, and after 9/11. Higher geopolitical risk
foreshadows lower investment, stock prices, and employment. Higher
geopolitical risk is also associated with higher probability of economic
disasters and with larger downside risks to the global economy.
The Recent GPR Index uses 10 newspapers and starts in 1985.
The Historical Index uses 3 newspapers and starts in 1900.
Country-specific indexes are
also constructed for 44 different countries.

Description
The Caldara and Iacoviello GPR index reflects automated text-search
results of the electronic archives of 10 newspapers: Chicago Tribune,
the Daily Telegraph, Financial Times, The Globe and Mail, The Guardian,
the Los Angeles Times, The New York Times, USA Today, The Wall Street
Journal, and The Washington Post. Caldara and Iacoviello calculate the
index by counting the number of articles related to adverse geopolitical
events in each newspaper for each month (as a share of the total number
of news articles).
The search is organized in eight categories:
War Threats (Category 1), Peace Threats (Category 2), Military Buildups
(Category 3), Nuclear Threats (Category 4), Terror Threats (Category 5),
Beginning of War (Category 6), Escalation of War (Category 7), Terror
Acts (Category 8). Based on the search groups above, Caldara and
Iacoviello also constructs two subindexes. The Geopolitical Threats
(GPRT) includes words belonging to categories 1 to 5 above. The
Geopolitical Acts (GPRA) index includes words belonging to categories 6
to 8.
