F15 Economic Integration

December 5, 2011

We study how credit supply shocks in the US, the euro area and Japan are transmitted to other economies. We use the recently-developed GVAR approach to model financial variables jointly with macroeconomic variables in 33 countries for the period 1983-2009. We experiment with inter-country links that distinguish bilateral trade, portfolio investment, foreign direct investment and banking exposures, as well as asset-side vs. liability-side financial channels. Capturing both bilateral trade and inward foreign direct investment or outward banking claim exposures in a GVAR fits the data better than using trade weights only. We use sign restrictions on the short-run impulse responses to financial shocks that have the effect of reducing credit supply to the private sector. We find that negative US credit supply shocks have stronger negative effects on domestic and foreign GDP, compared to credit supply shocks from the euro area and Japan. Domestic and foreign credit and equity markets respond clearly to the credit supply shocks. Exchange rate responses are consistent with a "flight to quality" to the US dollar. The UK, another international financial centre, is also responsive to the shocks. These results are robust to the exclusion of the 2007-09 crisis episode from the sample.

Since the 1970s the characteristics of international business cycles have changed and deeper economic integration has modified the features of cross-country comovement. We formally test for correlation shifts in measures of real economic activity and economic/financial integration. In Europe we find evidence of significantly higher correlations following the creation of the EMU in 1999 for several subgroups of countries. We detect significantly more pronounced correlations between Mexico and the US and between Mexico and Canada in North America after the enforcement of the NAFTA in 1994. Results are derived from an econometric framework based on nonparametric iterated stationary bootstrap methods, whose statistical reliability and performance we assess through Monte Carlo simulations.
