Hardie, I. 2005. The power of the markets? The international bond markets and the 2002 elections in Brazil. Review of International Political Economy 13, no. 1: 53-77.
"The data show that international bond market investors did not exit Brazil before the elections, putting in question whether they were the source of the riser in the cost of government borrowing that Mosley and others see as indicative of the market's strength. This suggests that our understanding of the actors responsible for market movements remains incomplete. The article, therefore, challenges the idea, common within international political economy, of 'the market' as a single entity, with common actions and policy preferences. The data presented here strongly suggest 'the market' is in reality made up of multiple heterogeneous actors often lacking any unity of opinion or purpose. After Lula's election victory, market prices recovered and the data show that international investors increased their investments in Brazil, despite slower policy implementation than market practitioners desired and the new government's social agenda. This supports a questioning of the true breadth of investors' policy interests and, therefore, influence" (53; from abstract)
Mosley (2003) makes the claim that developed countries experience narrow constraints from financial markets and that developing countries experience broad constraints. This piece criticizes whether or not developing countries really experience broad constraints, arguing that Brazil was still able to operationalize its social policies. "Instead, the dramatic negative fall in market prices before the Brazilian election, which caused not only an increase in the cost of international borrowing but also a severe, at times total, reduction in its availability, suggests that the distinction between developed and developing world may more significantly be seen in the strength of overall market constraint than in its breadth" (55).
One key aspect of this study, and building upon Mosely again and others, is the disaggregation of financial and market actors and an attempt to explore their separate motivations.
