An interesting paper (link here) from Andrew Rose titled International Financial Integration and Crisis Intensity (ADBI Working Paper 341 ).
The study looked at the causes of the 2008–2009 financial crisis "together with its manifestations", using a Multiple Indicator Multiple Cause (MIMIC) model that allows for simultaneous causality effects across a number of variables.
The analysis is conducted on a cross-section of 85 economies. The study focuses "on international financial linkages that may have both allowed the crisis to spread across economies, and/or provided insurance. The model of the cross-economy incidence of the crisis combines 2008–2009 changes in real gross domestic product (GDP), the stock market, economy credit ratings, and the exchange rate. The key domestic determinants of crisis incidence that [considered] are taken from the literature, and are measured in 2006: real GDP per capita; the degree of credit market regulation; and the current account, measured as a fraction of GDP. Above and beyond these three national sources of crisis vulnerability, [Rose added] a number of measures of both multilateral and bilateral financial linkages to investigate the effects of international financial integration on crisis incidence."
The study covers three questions:
- First, did the degree of an economy’s multilateral financial integration help explain its crisis?
- Second, what about the strength of its bilateral financial ties with the United States and the key Asian economics of the People’s Republic of China, Japan, and the Republic of Korea?
- Third, did the presence of a bilateral swap line with the Federal Reserve affect the intensity of an economy’s crisis?
Core conclusion: "more financially integrated economies do not seem to have suffered more during the most serious macroeconomic crisis in decades. This strengthens the case for international financial integration; if the costs of international financial integration were not great during the Great Recession, when could we ever expect them to be larger?"
Here's a snapshot of top 50 countries by the crisis impact:
Quite thought provoking. One caveat - data covers periods outside Sovereign Debt crisis period of 2010-present and the study can benefit from expanded data coverage, imo.
