This paper studies the effects of demand and supply shocks in the global crude oil market on several measures of countries' external balance, including the oil and non-oil trade balances, the current account, and changes in net foreign assets (NFA) during 1975-2004. We explicitly take a global...

Global oil markets were roiled by sharp price swings in 2008, and economists are still divided over the reasons for the unusual volatility. Those emphasizing fundamentals point to inelastic supply and demand curves, others view the phenomenon mostly as a result of financial investors flocking...

This paper investigates the causes of extreme fluctuations in commodity prices from 1990 to 2010. Analyzing two very distinct commodities-crude oil and fine wine, we find that macroeconomic factors are the main determinants of commodity prices. Although supply constraints have the expected...

Analyzing macroeconomic impacts of oil price changes requires first to investigate different sources of these changes and their distinct effects. Kilian (2009) analyzes the effects of an oil supply shock, an aggregate demand shock, and a precautionary oil demand shock. The paper's aim is to...

Assuming a social welfare function that smoothes expenditure, this paper calculates a sustainability benchmark for the non-mineral balance in Botswana that is based on a notion of a "permanent income" from non-renewable resources. It is derived by constructing a hypothetical annuity from...

This paper examines the environmental effects of mineral taxes in a framework that recognizes the importance of rates and cumulative externalities and proposes an appropriate corrective tax. It concludes that mineral resources taxation should combine neutral taxes with a dynamic Pigovian type...

This paper provides an overview of diamond mining in sub-Saharan African countries, and explores the reasons for substantial differences in their tax rates and fiscal revenues from the sector, which mainly arise from differences in the incentives for smuggling. In a theoretical model, we show...

Mali’s gold sector is an enclave with weak forward and backward linkages with the rest of the economy. Given the predominance of the fiscal transmission channel, it is important that the design of the mineral tax regime gives the state a fair share of the benefits. Using optimal control...

This paper takes stock of the economic performance of resource rich countries in the Middle East and North Africa (MENA) over the past forty years. While those countries have maintained high levels of income per capita, they have performed poorly when going beyond the assessment based on...

This paper, using a six-region DSGE model of the world economy, assesses the GDP and current account implications of permanent oil supply shocks hitting the world economy at an unspecified future date. For modest-sized shocks and conventional production technologies the effects are modest. But...
