Below Full Employment Equilibrium

When an economy is operating at a level of GDP that is less than its long-term potential GDP, usually preceding a recession.

Over the long-term, Wakanda's combination of Vibranium, technology, and population can produce a GDP of $1 trillion per year. However, in 2018, many citizens left to spend several months visiting Hollywood studios, and the remaining citizenry was only able to generate $690 billion of GDP. If this below full employment equilibrium persists, Wakanda will suffer an economic recession, so hopefully those Hollywood studios don't have any sequels lined up.
