Global banks, financial shocks and international business cycles: Evidence from an estimated model
This paper estimates a two-country model with a global bank, using US and Euro Area (EA) data, and Bayesian methods. The estimated model matches key US and EA business cycle statistics. Empirically, a model version with a bank capital requirement outperforms a structure without such a constraint. A loan loss originating in one country triggers a global output reduction. Banking shocks matter more for EA macro variables than for US real activity. Banking shocks account for about 3%-5% of the unconditional variance of US GDP and for 4%-14% of the variance of EA GDP. During the Great Recession (2007-09), banking shocks accounted for about 12%-20% of the fall in US and EA GDP, and for more than a third of the fall in EA investment and employment.
