Purpose

The purpose of this paper is to investigate the resource rents–quality-adjusted human capital nexus and the impact of quality of institutions.

Design/methodology/approach

For a large data set of 161 countries for the period 1996–2018 (yearly and 4-year periods), fixed effect estimation method is applied to investigate the impact of resource rents on quality-adjusted human capital and the role of quality of institutions on this relationship.

Findings

The paper found little evidence on the negative, significant and direct impact of total resource rents on quality-adjusted human capital. However, the results show that the negative effect of resource rents can be mediated by the quality of institutions. This result is robust to a long list of controls, different specifications and estimation techniques, as well as several robustness checks. Therefore, institutional quality seems to play a critical role in determining the indirect impact of natural resources on human capital. Moreover, the obtained results demonstrate that this resource adverse effect depends on the type of resource rents; in particular, high dependency on oil rents in developing countries appears to harm human capital.

Research limitations/implications

The paper shows that it is not obvious that total resource rents decrease human capital and found that the coefficient is no longer significant in the two-way fixed effects model. However, the analysis has emphasized the crucial role of political institutions in this relationship and has shown that countries with higher quality of institutions make the most of their resource rents transiting to a better human capital environment. This result is found to be robust to a list of controls, different specifications and estimation techniques, as well as several robustness checks. In addition, we demonstrate that not all resources affect human capital in the same way and found that oil rents have a significant negative effect on human capital. This is an important distinction since several countries are blessing from oil rents. From this we conclude that the effect of natural resources on human capital varies across different types of commodities. On the other hand, the interaction between institutions and the sub-categories of resource rents shows that oil rents can increase human capital only in developing countries with higher quality of institutions (above the threshold). This result is also still hold while using alternative measures of political institutions.

Practical implications

The results in this paper have important policy implications. In particular, results highlight important heterogeneities in the role resource rents to the economy. As international commodity prices have shown high volatility in recent years, it is important for policy makers to understand the rents. Rents which are the difference between the price of a commodity and the average cost of producing it can have different effects in the economy, including the human capital. It is shown that in countries with low-quality institutions, natural resource rents negatively affect institutional quality, leading to conflicts, corruption and fostering rent-seeking activities. Overall, this reinforces the elite at the power that, obviously, is interested in preserving the status quo. In other words, there is a vicious circle between resource rents and low-quality institutions that impedes institutional change. How to regulate this in the best possible way requires a good understanding of how resource rents are generated and appropriated for different sectors, their different effects and how people react to these rents. The evidence suggests the policy toward better political institutions may help countries to improve social outcomes such as health and education which offer high social returns.
