Abstract
We study the correlation of monthly excess returns for seven major countries over the period 1960-1990. The correlation is unstable over time and this instability can be explained by a time-trend, the influence of economic variables and a threshold effect (which proves that the correlation is higher when we expect a high level of volatility).
