The combination of rising current account surpluses in Asia and a growing current account deficit in the United States has raised concerns that the resulting imbalances pose a threat to the world economy, especially if they are reversed in a disorderly manner. Some experts believe that normal market forces will resolve these imbalances over time; others argue that policy-makers should facilitate the adjustment with policies that curb domestic demand in deficit countries and stimulate it in surplus countries. Little and Lafrance provide a guide to the major issues and controversies involved in the debate.

The ongoing process of price discovery in foreign exchange markets provides valuable information to certain market participants. Recent empirical findings suggest that aggregate measures of order flow convey information about the fundamental value of the exchange rate. Using a market microstructure approach, D'Souza reports on a two-year study of completed transactions within the Canadian and Australian exchange rate markets to examine the relationship between exchange rate returns and trades initiated in different locations. Based on the information content of the trades, he finds that geographic location and hours of operation are two of the factors driving informed interdealer trading.

The author examines recent trends in sterilized intervention among emerging-market economies, to determine the size and extent of this policy in relation to earlier periods of heavy reserve accumulation. He then analyzes whether the domestic costs and risks of substantial and prolonged sterilization are beginning to manifest themselves.

World economic growth has been remarkably strong over the past three years, averaging close to 4 1/4 per cent, and it is expected to stay around 4 per cent this year and next.

We develop a five-region version (Canada, an oil exporter, the United States, emerging Asia and Japan plus the euro area) of the Global Economy Model (GEM) encompassing production and trade of crude oil, and use it to study the international transmission mechanism of shocks that drive oil prices.

The authors explore the usefulness of macroeconomic models in analyzing global economic developments by examining movements in commodity prices between July 2007 and July 2008. They use the Bank of Canada's version of the Global Economy Model and investigate the longer-term outlook for commodity prices by constructing two different, globally consistent, scenarios for emerging Asia.

In this article, the authors explain the methodology used to construct real exchange rate (RER) indexes. They also compare and assess various Canadian RER indexes from both an empirical and conceptual standpoint. The authors conclude that both theory and empirical evidence suggest that the best RER indexes are those based on unit labour costs. They note, however, that, for practical reasons, policy-makers should also consider RER indexes based on prices when formulating monetary policy.
