Let us briefly look at some figures: a)  as a result, the degree of real economic openness of many countries has increased significantly (as measured by total exports and imports of goods and services as a ratio of GDP).
For example, in the German case, the relevant figure amounts to roughly 75% at the current juncture, compared with just over 60% in 1990.  b)  global trade is also boosted by the ongoing internalisation of production structures. These are most visible by looking at the growing stock of FDI.
