This paper presents a multi‐sectoral general oligopolistic equilibrium trade model in which unionized and non‐unionized sectors interact. In our model, the proportion of unionized sectors is endogenously determined. We show that this proportion depends on exogenous parameters such as productivity, population, number of firms, union costs and labor union formation. We also show that trade openness between symmetric countries raises the competitive wage and lowers the proportion of unionized sectors.

工会和国际贸易的内生决策：一般寡头均衡模型分析

本文提出了一个多部门的一般寡头均衡贸易模型，其中工会化和非工会化的部门相互作用。在我们的模型中，工会部门的比例是内生确定的。我们表明，这一比例取决于外在参数，例如生产率，人口，公司数量，工会成本和工会组成。我们还表明，对称国家之间的贸易开放提高了竞争性工资，降低了工会部门的比例。
