Purpose

The implications of trade on developing economies have generated substantial debates with most studies focussed on “openness in the policy”. Hence, the purpose of this study is to focus on “openness in practice”.

Design/methodology/approach

This study uses two models and employed the vector error correction model and structural vector autoregression, first, to examine the sectoral effects; second, to investigate the efficacy of neoclassical and new trade theories; and third, to analyse the effect of trade openness shock on Nigerian labour market performance.

Findings

The results of the first model showed that trade openness has an adverse effect on employment and wages in both the agriculture and manufacturing sectors. Likewise, the study concludes that the new trade theory explains trade's behaviour on employment and wages in Nigeria. The second model showed that the effect of error shock from trade openness affected wages more than employment.

Research limitations/implications

The study ignores the distributional effects due to unavailability of data.

Practical implications

The study suggested, amongst others, the need for policies mix on the labour market via a coherent set of initiatives in other to increase the competitiveness of Nigeria in the international market.

Originality/value

Most studies focussed on openness in policy through the channels identified in the literature. However, this study investigates these channels in “openness in practice” and investigates trade theories' efficacy on manufacturing and agricultural sectors in Nigeria, which has been neglected in the literature.

贸易开放渠道和劳动力市场表现：来自尼日利亚的证据

目的

贸易对发展中经济体的影响引发了大量辩论，大多数研究都集中在“政策的开放性”上。因此，本研究的目的是关注“实践中的开放性”。

设计/方法/方法

本研究采用两种模型，分别采用向量误差修正模型和结构向量自回归模型，首先考察部门效应；第二，考察新古典主义和新贸易理论的有效性；第三，分析贸易开放冲击对尼日利亚劳动力市场表现的影响。

发现

第一个模型的结果表明，贸易开放对农业和制造业的就业和工资都有不利影响。同样，该研究得出的结论是，新贸易理论解释了贸易对尼日利亚就业和工资的影响。第二个模型表明，贸易开放的误差冲击对工资的影响大于对就业的影响。

研究限制/影响

由于数据不可用，该研究忽略了分布效应。

实际影响

该研究表明，除其他外，需要通过一系列连贯的举措在劳动力市场上进行政策组合，以提高尼日利亚在国际市场上的竞争力。

原创性/价值

大多数研究都通过文献中确定的渠道关注政策的开放性。然而，这项研究在“实践中的开放性”中调查了这些渠道，并调查了贸易理论对尼日利亚制造业和农业部门的有效性，这在文献中被忽视了。
