Abstract: Purpose - Despite the government’s efforts to protect domestic industries from foreign competition through tariffs, the industrial sector’s contribution to GDP continued to decline in Nigeria. Based on the scenario, this study assessed the symmetric and asymmetric effects of tariffs on industrial performance in Nigeria for the period 1988–2021. Tariff was captured with a tariff rate applied to the weighted mean of all products, while industry value added as a percent of GDP was used as a proxy for industrial performance. Design/methodology/approach - Linear and nonlinear ARDL techniques were used for the analysis. Findings - The symmetric (linear ARDL) results revealed that tariffs have a significant positive effect on industrial performance in both the short and long term. The asymmetric (nonlinear ARDL) results showed that a long-term asymmetry exists between tariffs and industrial performance. It revealed positive effects on industrial performance for both positive and negative tariff changes, with the negative change having a greater impact. Practical implications - Generally, the results showed that the use of tariffs to protect domestic industries in Nigeria promotes industrial performance. The implication is that the declining contribution of the industrial sector to GDP in Nigeria is not a result of the tariff policy. It shows that the government should look beyond tariff policy to enhance the industrial contribution to GDP. Originality/value - Nigeria should exercise caution in using tariff policies to protect domestic industries to avoid retaliation from their trade partners that could reverse the positive impacts.
