When you fly from Norman Manley airport to Miami, your J$50 000 doesn't go very far at the duty-free counter. The exchange rate (J$155 = US$1) shrinks your wallet immediately. Meanwhile, that 2018 Toyota Corolla you bought new for $4M? It's now worth only $2.5M, depreciation in action. Both are CSEC favourites. Memory Hook / Mnemonic: AD & EX.
