Export Product Diversification and Public Revenue’s Dependence on Resource Revenue

This article tries to reconcile two major priorities for countries, notably resource-rich countries on the international development agenda: export product diversification with a view to helping them better integrate into the multilateral trading system and tax reforms with a view to reducing the dependence of total public revenue on resource revenue, and therefore developing a more sustainable stream of public revenue. The analysis therefore involves examining empirically the impact of export product diversification on countries’ overall public revenue dependence on resource revenue, this dependence being measured by the share of resource revenue in total public revenue. The empirical analysis shows that export product diversification exerts a negative and significant impact on resource revenue share of total public revenue, and therefore could help facilitate tax reforms towards lower resource revenue dependence. Hence, while tax policy is the main policy tool to conduct tax reforms, export product diversification would likely contribute to facilitating the implementation of these reforms.
