This paper examines whether the real exchange rates of commodity-exporting countries and the real prices of their commodity exports move together over time. Using International Monetary Fund (IMF) data on the world prices of 44 commodities and national commodity export shares, we construct new monthly indices of national commodity export prices for 58 commodity-exporting countries over 1980 -2002. Evidence of a long-run relationship between national real exchange rate and real commodity prices is found for about one-third of the commodity-exporting countries. The long-run real exchange rate of these 'commodity currencies' is not constant (as would be implied by purchasing power parity-based models) but is time varying, being dependent on movements in the real price of commodity exports.

This paper develops an endogenous growth model of the influence of public investment, public transfers, and distortionary taxation on the rate of economic growth. The growth-enhancing effects of investment in public capital and transfer payments are modeled, as is the growth-inhibiting influence of the levying of distortionary taxes which are used to fund such expenditure. The theoretical implications of the model are then tested with data from 23 developed countries between 1971 and 1988, and time seriescross sectional results are obtained which support the proposed influence of the public finance variables on economic growth.

This paper employs a dynamic multi-country framework to analyze the international macroeconomic transmission of El Niño weather shocks. This framework comprises 21 country/region-specific models, estimated over the period 1979Q2 to 2013Q1, and accounts for not only direct exposures of countries to El Niño shocks but also indirect effects through third-markets. We contribute to the climate-macroeconomy literature by exploiting exogenous variation in El Niño weather events over time, and their impact on different regions cross-sectionally, to causatively identify the effects of El Niño shocks on growth, inflation, energy and non-fuel commodity prices. The results show that there are considerable heterogeneities in the responses of different countries to El Niño shocks. While Australia, Chile, Indonesia, India, Japan, New Zealand and South Africa face a short-lived fall in economic activity in response to an El Niño shock, for other countries (including the United States and European region), an El Niño occurrence has a growth-enhancing effect. Furthermore, most countries in our sample experience short-run inflationary pressures as both energy and non-fuel commodity prices increase. Given these findings, macroeconomic policy formulation should take into consideration the likelihood and effects of El Niño weather episodes.

We employ a set of sign restrictions on the generalized impulse responses of a Global VAR model, estimated for 38 countries/regions over the period 1979Q2-2011Q2, to discriminate between supply-driven and demand-driven oil-price shocks and to study the time pro…le of their macroeconomic e¤ects for di¤erent countries. The results indicate that the economic consequences of a supply-driven oil-price shock are very di¤erent from those of an oil-demand shock driven by global economic activity, and vary for oil-importing countries compared to energy exporters. While oil importers typically face a long-lived fall in economic activity in response to a supply-driven surge in oil prices, the impact is positive for energy-exporting countries that possess large proven oil/gas reserves. However, in response to an oil-demand disturbance, almost all countries in our sample experience long-run in ‡ationary pressures and a short-run increase in real output.
