Effects of Road Infrastructure on Employment, Productivity and Growth: An Empirical Analysis at Country Level

Abstract

This article estimates the effect of transport infrastructure at country level, on employment, productivity (total factor productivity (TFP), and their components technical efficiency–pure and the scale—and technological change) and economic growth, using a dynamic panel approach. We focus on two broad categories of transport infrastructure: (1) road density and (2) road paved. Using dynamic panel GMM system estimation, we find positive effects of road density and road paved on total factor productivity (TFP) in countries with middle low and low income (using parametric and non-parametric estimations). On the other hand, and taking into account the Deng’s hypothesis of a nonlinearity relationship between transport infrastructure and economic growth (Deng, 2013, Transport Reviews 33(6): 686–99), we found empirical evidence about a Kuznets curve when we consider the percentage of roads paved. In countries with middle low and low income, we also found a Kuznets curve between road density and unemployment. JEL Classification: H54, R42, O47, O4, C23

Determinant of Capital Efficiency and Its Impact on Economic Growth: Empirical Evidence in East Java

“…These results indicate that regions with access to adequate or inadequate road infrastructure do not have significant differences in capital efficiency. The findings of this study are different from the Dwi Budi Santoso Determinant of Capital Efficiency and Its Impact on Economic Growth research conducted by Álvarez et al (2016), Arbués et al (2015), Deng (2013), Laborda & Sotelsek (2019), Melo et al (2013). One plausible explanation is that increasing the availability of steady access roads (good and medium quality) does not necessarily reduce transportation and logistics costs in the movement of goods.…”

“…This infrastructure can reduce transportation and logistics costs borne by the business world, both in the mobility of production factors and final demand. (Álvarez et al, 2016;Arbués et al, 2015;Deng, 2013;Laborda & Sotelsek, 2019;Melo et al, 2013). Providing stable roads is considered necessary in reducing transportation and logistics costs because most of the mobilization of goods and services in East Java still relies on land transportation modes.…”

Does Implementing Trade Facilitation Improve Social Welfare? In Case of ASEAN

“…Transport infrastructure is one of the issues that needs to be improved in TF. People from various places can quickly obtain employment prospects due to the ease with which they can move around them (Chakrabarti, 2018;Glaeser & Ponzetto, 2018;Hernandez et al, 2020;Laborda & Sotelsek, 2019; H. Nguyen, 2020;Yu & Luu, 2022). They can find occupations that match their abilities, allowing them to enhance their income and provide better educational possibilities for their children (Jouanjean et al, 2016;Sakyi et al, 2018).…”

Transport Infrastructure Impact on Regional Unemployment – Evidence from Vietnam

“…A well-developed transport system can both increase the number of workers and minimize income inequality (Zhang et al, 2017). Transport infrastructure is critical for developing countries because it provides many options for people to access jobs (Hernandez et al, 2020;Laborda & Sotelsek, 2019). As a result, the Vietnamese government has consistently prioritized transport infrastructure construction and upgrades.…”

“…The System Generalized Method of Moments (SGMM) estimator is used with data on transport infrastructure and unemployment across Vietnam's 63 provinces and regions to analyze this effect. Many studies have employed this estimator in recent years (Laborda & Sotelsek, 2019;Onuoha & Agbede, 2019;Tsaurai, 2020;Yakubu & Muhammed, 2021;Yu & Luu, 2022). The findings of the baseline regression ordinary least squares (OLS) and fixed effects (FE) models reveal that this impact exists.…”
