Shifting Commodity Markets in a Globalized World
A survey of the complex and intertwined set of forces behind the various commodity markets and the interplay between these markets and the global economy. Summarizes a rich set of facts combined with in-depth analyses distillated in a nontechnical manner. Includes discussion of structural trends behind commodities markets, their future implications, and policy implications.
The Future of Oil and Fiscal Sustainability in the GCC Region
The oil market is undergoing fundamental change. New technologies are increasing the supply of oil from old and new sources, while rising concerns over the environment are seeing the world gradually moving away from oil. This spells a significant challenge for oil-exporting countries, including those of the Gulf Cooperation Council (GCC) who account for a fifth of the world’s oil production. The GCC countries have recognized the need to reduce their reliance on oil and are all implementing reforms to diversify their economies as well as fiscal and external revenues. Nevertheless, as global oil demand is expected to peak in the next two decades, the associated fiscal imperative could be both larger and more urgent than implied by the GCC countries’ existing plans.
International Risk Sharing During the Globalization Era
Though theory suggests financial globalization should improve international risk sharing, empirical support has been limited. We develop a simple welfare-based measure that captures how far countries are from the ideal of perfect risk sharing. We then take it to data and find international risk sharing has, indeed, improved during globalization. Improved risk sharing comes mostly from the convergence in rates of consumption growth among countries rather than from synchronization of consumption at the business cycle frequency. Our finding explains why many existing measures fail to detect improved risk sharing-they focus only on risk sharing at the business cycle frequency.
The International Diversification Puzzle when Goods Prices Are Sticky
This paper develops a two-country monetary DSGE model in which households choose a portfolio of home and foreign equities, and a forward position in foreign exchange. Some nominal goods prices are sticky. Trade in these assets achieves the same allocations as trade in a complete set of nominal state-contingent claims in our linearized model. When there is a high degree of price stickiness, we show that not much equity diversification is required to replicate the complete-markets equilibrium when agents are able to hedge foreign exchange risk sufficiently. Moreover, temporarily sticky nominal goods prices can have large effects on equity portfolios even when dividend processes are very persistent.
Oil Prices and the Global Economy
This paper presents a simple macroeconomic model of the oil market. The model incorporates features of oil supply such as depletion, endogenous oil exploration and extraction, as well as features of oil demand such as the secular increase in demand from emerging-market economies, usage efficiency, and endogenous demand responses. The model provides, inter alia, a useful analytical framework to explore the effects of: a change in world GDP growth; a change in the efficiency of oil usage; and a change in the supply of oil. Notwithstanding that shale oil production today is more responsive to prices than conventional oil, our analysis suggests that an era of prolonged low oil prices is likely to be followed by a period where oil prices overshoot their long-term upward trend.
Global Liquidity
What is global liquidity and how does it affect an economy? The paper addresses that question by looking at liquidity from two different perspectives: global liquidity as availability of funds in safe and risky asset markets. This distinction between safe and risky asset markets is important due to market segmentation, which called for unconventional monetary policy to restore a function of risky asset markets. To analyze the effect of global liquidity, I construct proxy variables and then asses how they affect an emerging economy whose interest rate is affected by a world risk-free rate and a risk premium. Using the data from four major Latin American countries, I find that these two aspects of global liquidity have similar effects on economic performance in emerging market economies except for their effect on inflation.
Excerpt: Shifting Commodity Markets in a Globalized World
This paper discusses developments and prospects for energy, metals, and food markets since the early 2000s, the start of what is termed a commodities supercycle—the rise of commodity prices over a decade or more as a result of a rapid urbanization and an expansion of infrastructure. Macroeconomists often assume that technological innovation is exogenous (driven largely by external factors or forces), but this volume documents how innovation in energy markets is directly affected by prices. When oil, natural gas, or fossil fuels become scarce, prices increase. This stimulates innovation and the adoption of new technologies and techniques for recovery and use of these resources. Conversely, ...
