This study assesses the asymmetric impact of financial development, trade openness, and environmental degradation on economic growth in Venezuela between 1980 and 2019 using the nonlinear autoregressive distributed lag model. Findings from the bounds test indicate the presence of cointegration between the series in the model. Further findings from the study showed evidence of a significant negative long-run impact of negative shocks to financial development on long-run economic growth, thereby confirming that declining financial development hinders economic growth in Venezuela. Furthermore, positive and negative shocks of trade openness show a positive impact on economic growth in the long run. Meanwhile, in the short-run, negative shocks to financial development negatively impacts economic growth, while one year lagged negative shocks to financial development improve the short-run economic growth. More so, results from the long-run asymmetric test reveal that only financial development has a significant asymmetric effect on economic growth. However, errors to the system are adjusted at a speed of 38%. This study, thus, recommends the improvement of the financial sector and removing barriers to trade where possible, while adopting low carbon emissions for economic growth.
本研究使用非线性自回归分布滞后模型评估了 1980 年至 2019 年期间委内瑞拉金融发展、贸易开放和环境恶化对经济增长的非对称影响。边界检验结果表明模型中各序列之间存在协整关系。研究的进一步结果表明,金融发展的负冲击对长期经济增长有显著的负向长期影响,从而证实了金融发展的下降阻碍了委内瑞拉的经济增长。此外,贸易开放的正负冲击在长期内对经济增长都有正向影响。同时,在短期,金融发展的负冲击对经济增长有负面影响,而金融发展的滞后一年的负冲击则会改善短期经济增长。此外,长期非对称检验的结果表明,只有金融发展对经济增长有显著的非对称影响。然而,系统误差以 38%的速度进行调整。因此,本研究建议改善金融部门,尽可能消除贸易壁垒,同时采用低碳排放以促进经济增长。
