中文摘要 | 本文旨在說明,當勞動供給內生決定時,貿易自由化可能不再是小國的最適貿易政策。在要素稟賦外生給定的傳統貿易模型中,小國長期的最適選擇必然為自由貿易,故政策權衡的重點在於應緩慢或立即展開貿易自由化。但是,當休閒時數納入個人的經濟決策時,內生化的勞動供給將使得減稅對產出及福利的效果變得不確定,導致貿易政策的權衡取決於工資彈性與進口支出比例之間的關係,以及進出口部門的要素相對密集程度。由本文結論可知,除非工資的價格彈性大於進口支出比例,而且出口部門呈現相對資本密集的型態,否則貿易自由化不會是最適政策,政府應維持適當的貿易管制以極大化本國福利。 |
英文摘要 | This paper shows that trade liberalization may not the optimal commercial policy when labor supply is endogenous. In a typical Heckscher-Ohlin intertemporal framework with exogenous resources, the implementing program will focus on the optimal timing of trade liberalization, that is, to determine “shock” or “gradualism” in trade reform during the transitional finite period. Once individual agents can optimize their leisure time through utility-maximization, a tariff reduction will create ambiguous effects on the labor supply, the production of different goods, and the social welfare. As we present in this paper, the reform program depends on three conditions: the elasticity of wage with respect to import prices, the spending proportion on imports, and relative factor intensity. Trade liberalization is a contingent implementation only if the price elasticity of wage is more than the spending proportion on imports and exportable goods are capital-intensive. However, there is often a welfare gain from non-zero optimal tariff. |
