Abstract

This paper investigates whether infrastructure development helps poor economies escape low‐income traps or transition to higher‐income levels. Infrastructure has always been central to development policies and is critical for achieving the SDGs. While empirical studies have explored infrastructure's effects on growth, inequality, and poverty, this paper takes a different approach. We adopt a new country classification and infrastructure index to examine infrastructure's role in 91 countries from 1985 to 2014, using probabilistic choice models. Our results show that although infrastructure development does not have a statistically significant effect on the likelihood of countries falling into poverty traps, it plays a crucial role in differentiating high‐income countries from poor and emerging economies. We also find that for infrastructure to be effective, other conditions, such as human capital and institutional quality, must be met. Therefore, infrastructure alone is insufficient to drive economic transformation. These findings have important policy implications for low‐income countries, emphasizing that infrastructure must be integrated with other enabling factors to foster economic development. For high‐income countries, infrastructure investment helps sustain progress and resilience. 本文探讨基础设施发展是否有助于贫困经济体摆脱低收入陷阱或向高收入水平转型。基础设施一直是发展政策的核心, 对实现可持续发展目标至关重要。尽管实证研究已经探讨了基础设施对经济增长、不平等和贫困的影响, 但本文采取了不同的方法。我们采用新的国家分类和基础设施指数, 运用概率选择模型, 考察了1985年至2014年91个国家的基础设施作用。结果表明, 尽管基础设施发展对国家陷入贫困陷阱的可能性没有统计学上的显著影响, 但它在区分高收入国家与贫困和新兴经济体方面发挥着至关重要的作用。我们还发现, 基础设施要发挥作用, 必须满足其他条件, 例如人力资本和制度质量。因此, 仅靠基础设施不足以推动经济转型。这些发现对低收入国家具有重要的政策意义, 强调基础设施必须与其他促进经济发展的有利因素相结合。对于高收入国家而言, 基础设施投资有助于维持经济发展的持续性和韧性。 Este artículo investiga si el desarrollo de infraestructura ayuda a las economías pobres a superar las trampas de la pobreza o a acceder a niveles de ingresos más altos. La infraestructura siempre ha sido fundamental para las políticas de desarrollo y es crucial para el logro de los ODS. Si bien estudios empíricos han explorado los efectos de la infraestructura en el crecimiento, la desigualdad y la pobreza, este artículo adopta un enfoque diferente. Adoptamos una nueva clasificación de países e índice de infraestructura para examinar el papel de la infraestructura en 91 países entre 1985 y 2014, utilizando modelos de elección probabilística. Nuestros resultados muestran que, si bien el desarrollo de infraestructura no tiene un efecto estadísticamente significativo en la probabilidad de que los países caigan en trampas de pobreza, desempeña un papel crucial para diferenciar a los países de altos ingresos de las economías pobres y emergentes. También observamos que, para que la infraestructura sea eficaz, se deben cumplir otras condiciones, como el capital humano y la calidad institucional. Por lo tanto, la infraestructura por sí sola no es suficiente para impulsar la transformación económica. Estos hallazgos tienen importantes implicaciones políticas para los países de bajos ingresos, ya que enfatizan que la infraestructura debe integrarse con otros factores facilitadores para fomentar el desarrollo económico. Para los países de altos ingresos, la inversión en infraestructura ayuda a mantener el progreso y la resiliencia.
