Abstract
Risky Business: The Social Construction of Country Risk Ratings
By: Diogo Lemieszek Pinheiro
The objective of this project is to understand the origins and impact of Sovereign
and Country risk ratings. These ratings were created by key financial agencies and serve
as a way of guiding a significant part of investment in developing nations. This project
focuses on three key issues related to these risk ratings: their adoption, their
implementation, and their current impact on policy. The first issue addresses how an
abstract idea ( i.e., how financial risks should be measured) gained support and spread
throughout the world. The second issue concerns how this idea was implemented by
numerous financial service agencies. Finally, the third issue is about the impact that these
ratings have on a nation's ability to borrow money, therefore influencing policy.
Theoretically, this project deals with one of the key debates in the social sciences: are
markets rational and efficient, or does uncertainty lead to the adoption of certain
measures and policies because they are culturally and politically legitimate? To answer
this question, this dissertation employs quantitative analyses, looking at both the
statistical trends and the substantive discussions that involve the creation of these ratings.
More specifically, I use different statistical techniques to show that the spread of risk
ratings are not solely driven by market factors, and that these ratings persist despite
known inaccuracies in their methodology. They are measures of compliance with the
existing policy paradigm, and fail to adequately capture investment risk. As such, they
play a key role in the adoption of certain policies even in the face of financial crises
worldwide.
