This paper proposes an integrated approach to fiscal policy analysis in oil producing countries (OPCs) geared towards addressing their unique and complex policy challenges. First, an accurate assessment of the fiscal stance in OPCs can be obscured by large and volatile oil revenue flows. Second,...

This paper analyzes Solomon Islands’ ongoing reforms concerning of the mineral taxation regime and the fiscal impact of mineral resources. The analysis shows that mineral revenue could be substantial, provided that mineral prices remain strong in the medium term. Enforcing the tax...

This paper suggests that it is essential to save a substantial portion of mineral revenues now to ensure fiscal sustainability for a post-diamond period. Taking the non-mineral primary balance into account can help clarify desirable fiscal policies. Botswana’s real effective exchange rate...

Oil-producing countries have benefited from rising oil prices in recent years. The increase in oil exports and oil revenues has had major implications for these countries. These developments have revealed how governments manage their fiscal policies in light of changing oil-market conditions and...

Payments for ecosystem services should be informed by how both the providing-resource and the downstream resource are managed. We develop an integrated model that jointly optimizes conservation investment in a watershed that recharges a downstream aquifer and groundwater extraction from the...

Optimal recycling of minerals can be thought of as an integral part of the theory of the mine. In this paper, we consider the role that wastewater recycling plays in the optimal extraction of groundwater, a renewable resource. We develop a two-sector dynamic optimization model to solve for the...

Inasmuch as water demand is multifaceted, infrastructure planning should be part of a general specification of efficient quantities and qualities of water deliveries over time. Accordingly, we develop a two-sector dynamic optimization model to solve for the optimal trajectories of groundwater...

General principles of groundwater management for a single aquifer are extended to the management of multiple water resources, including additional aquifers, recycled wastewater, and desalinated seawater. Optimal groundwater extraction can be incentivized by pricing according to the Pearce...

We provide a synthesis of the economics of groundwater with a focus on optimal management and the Pearce equation for renewable resources. General management principles developed through the solution of a single aquifer optimization problem are extended to the management of multiple resources...

This paper fills a gap in the macroeconomic literature on renewable sources of energy. It offers a definition of green investment and analyzes the trends and determinants of this investment over the last decade for 35 advanced and emerging countries. We use a new multi-country historical dataset...
