According to gottman's couple typology, which type of couple handles disagreements in a way that is open, but discussions tend to be competitive rather than cooperative?

I  believe the answer is: Volatile.
Volatile couple much more likely to happen if both partners in the relationship have a strong character and domineering tendencies.
So rather than seeking the best solution when arguing with the partner, they seek a way to obtain some sort of victory toward another in order to obtain the dominant hand in the relationship.

In financial aspects, a depression is a sustained, long haul downturn in monetary movement in one or more economies. it is a more extreme monetary downturn than a recession, which is a slowdown in financial action through the span of a typical business cycle. a depression is an irregular and extreme type of recession. so depression is always followed by recession but it is not correct to state that a depression always follow a recession.
