Notes: This table reports the estimated change in aggregate volatility in absolute terms (∆σA2 ), while evaluating σ2 ,
ρ, and h at the 25th and 75th percentiles of their respective distributions. It also reports the ratio of the two. The
trade opening used in this table is equivalent to moving from the 25
th to 75th percentile of trade openness in the
sample.
