Indicator of real-time perceptions of financial market stress based on machine classification of Economist Intelligence Unit monthly country reports.
Currently the Index is estimated for all EIU countries from 2003 through 2011.
Responding to financial market disruptions is a defining challenge for policymakers and a central topic of political research. Yet established measures of financial conditions have significant shortcomings. Annual binary crisis variables limit our ability to explore non-linear relationships and the political effects of rapidly changing conditions. Continuous indicators have their own flaws in operationalization and reproducability. We create a continuous measure of real-time perceived stress using a kernel principal component analysis (KPCA) of Economist monthly country reports. We demonstrate the usefulness of our measure by showing that it more accurately captures the effect of financial market stress levels on electoral volatility. We also show how KPCA can be used to efficiently summarize large quantities of texts into cross-sectional time-series variables.
The following figure shows a selection of financial market stress perceptions scores (solid grey lines). It also compares these scores to other measures of financial market stress and crisis. Dashed lines show Romer and Romer (2015). Red boxes are for Reinhart and Rogoff (2009). Yellow boxes are for Laeven and Valencia (2013).
