Question

Based on the Balassa-Samuelson model, when the growth of productivity in the domestic tradable goods sector relative to the non-tradable goods sector exceeds that of the foreign tradable goods sector relative to its non-tradable goods sector, what phenomenon will this cause?
(A) The real exchange rate appreciates.
(B) The real exchange rate depreciates.
(C) Inflation rises.
(D) Inflation falls.

Accepted Answer

正確答案為 A。 Balassa-Samuelson 模型：本國貿易財部門生產力相對成長較快→實質匯率升值。 (A) 【BS效應核心】正解。BS 模型指出，當本國貿易財部門相對非貿易財部門的生產力成長，超過外國對應比率時，本國非貿易財價格上漲較快，整體物價水準相對上升，導致實質匯率升值 (appreciation)。 (B) 【方向顛倒】錯誤。方向顛倒。生產力較高的國家實質匯率應升值而非貶值，這正是為何已開發國家物價水準普遍高於開發中國家的原因。
