Si tratta di un testo che analizza i trend di spesa e di consumo in una particolare regione.
Questo il contesto:
With the acquisition of wealth, concomitant spending has evolved through a younger generation. Fuelled by half a decade of strong population growth, the Gulf’s society is predominantly a youthful one. About 26 million people, 55% of the overall population, are below 30 years of age. It is within this generational divide that the difference in the way luxury is perceived can be witnessed.

Trovo qualche hit per concomitant spending e concomitant expenditure, quindi mi sembra che si tratti di un'espressione specifica.
Grazie
